1. iThreadTimer ActiveX property editor crashing issue fixed. Would occur when

setting any timer Enabled property to True and clicking the Ok or Apply

button.

New Features:

1. Added support for Embarcadero XE7 (Delphi & C++ Builder).

2. Added support for Embarcadero XE8 (Delphi & C++ Builder).

3. Added full support for 32-Bit and 64-Bit application development...

o All Embarcadero Development Environments starting with XE2.

o Includes 32-Bit and 64-Bit OCX Builds.

o Includes 32-Bit and 64-Bit OPC Distribution Builds (iOPC5_32.dll &

iOPC5_64.dll)

o Supports 64-Bit Debugging on any Microsoft 64-Bit OS.

4. Upgraded iPlot control drawing routines for increased performance.


Bug Fixes:

1. None.

New Features:

1. Upgraded controls to support Embarcadero XE6 (Delphi + C++ Builder).


Bug Fixes:

1. Fixed mouse increment/decrement issue on the iSwitchQuad control. You

would not be able to change the ValueX or ValueY property value while the

CTRL or SHIFT key was being held down.

2. Fixed plot channel YMean calculation bug. The GetYMean function would

always return 0.

3. Fixed GetYInterpolated function return value issue. The return value is a

boolean indicating if the returned value is valid or not. For interpolated values,

the boolean return value was always correct. For the case where no

interpolation was necessary because the target x-value match the x-value of an

actual data-point and the data-point y-value was null, the returned value was

incorrectly reported as valid. Because the plot control data-cursor utilizes

the GetYInterpolated function, these fix also corrects the same issue with the

data-cursor.

New Features:





5. Upgraded design-time licensing manager to support development on 64-Bit

operating systems.


Bug Fixes:

1. Fixed iKeyBoard control SavePropertiesToFile issue. The control was not

saving out the settings for individual buttons.

2. Fixed various Unicode issues with using the Plot Control's

SavePropertiesToFile and LoadPropertiesFromFile methods.

New Features:

1. Added Transparent Support to iRotationDisplay rotated images.

2. Upgraded plot control channel running statistics to support nulls and empties.

3. Upgraded All Instrumentation Products to support C++ Builder XE.

4. Upgraded All Instrumentation Products to support Delphi XE.

5. Upgraded All Instrumentation Products to support RAD Studio XE.


Bug Fixes:

1. Fixed LoadPropertiesFromFile bug which would misinterpret carriage-

return/line-feed characters. The result would be multi-line text being corrupted

into single-line text strings.

2. Fixed iSwitchSlider Unicode display bug.

3. Fixed iSwitchRotary Unicode display bug.

4. Fixed data-cursor y-value issue when the channel was in Differential mode and

the Snap-To-Data-Point option was enabled. The data-cursor would display the

value for the previous data-point.

5. Fixed double key-press bug. Affected control's which support increasing or

decreasing their value through key presses. For example, pressing the up-arrow

key on the SwitchSlider or SwitchRotary would cause the value to increase by

2 steps. (Note: This bug would not occur on Vista or Windows 7).

6. Added ClipToAxes property to the Plot/XYPlot control ActiveX iPlotLimitX

interface. This property has always existed, was always accessible through the

property editor, but was missing on the ActiveX version iPlotLimitX COM

interface (Was not an issue with the VCL version).

New Features:

1. Added support for Delphi 2010.

2. Added support for C++ Builder 2010.

3. Added Support for RAD Studio 2010.

4. Upgraded all ActiveX controls to support Unicode.

5. Upgraded all property editors to display Unicode strings.

ActiveX and VCL Version 4.0.2 Service Pack 1

Bug Fixes:

1. Fixed bug on the Plot control DataCursor which would occur when multiple x-

axis where stacked end-to-end and the x-axis was in data-time mode. There

would be a small error when the data-cursor calculated the x-value to display in

the hint box.

2. Fixed AutoFrameRate issue which would result in the last frame not always

being painted. Previously, when data collection was suspended, it was

necessary to call the invalidate method to ensure the last frame was always

painted. With this fix, you no longer need to call the Invalidate method.

New Features:

1. Added PointerFillEnabled and PointerFillColor properties to the iSwitchSlider

control.

2. Added the OnTimeBaseSecDivChange event to the iScope control.

3. Added the OnMouseDownObject, OnMouseUpObject, OnMouseMoveObject,

and OnDblClickObject events to the iObjectCanvas control. These events will

fire when the specific mouse effect occurs on a object within the control. The

event parameters includes the handle for the specific object causing the event to

fire.

4. Added Support for CodeGear Delphi & C++ Builder 2009.

5. Added CustomizeLabelEventText property to the PlotAxis object. This new

property is used in conjunction with the OnXAxisCustomizeLabel event. It is

only necessary to use this property in VBScript and JavaScript applications

because HTML does not support passing text by reference. So in these types of

applications, do not use the ALabel parameter passed in the event to modify the

label text, and instead use this new property.


Bug Fixes:

1. None.

New Features:

1. Added Support For Borland's Turbo Delphi.

2. Added Support For Borland's Turbo C++.

3. Added Support For Borland's RAD Studio 2007.

4. Added Support for Borland's Delphi 2007.

5. Added Support For Borland's C++ Builder 2007.

6. Added PointerFillEnabled and PointerFillColor properties to the iSlider control.

7. Added the following events to the iPlot and iXYPlot controls...

o OnGetMouseCursorChannel

o OnGetMouseCursorXAxis

o OnGetMouseCursorYAxis

o OnGetMouseCursorDataCursor

o OnGetMouseCursorDataView

o OnGetMouseCursorLegend

o OnGetMouseCursorLimit

o OnGetMouseCursorTable

o OnGetMouseCursorAnnotation


Bug Fixes:

1. Fixed property editor lockup issues in ActiveX containers when using the

Color, Font, and etc dialogs.

2. Fixed scrolling issue with the plot legend. Would occur when the plot control

was first resized such that not all legend items could be displayed and the scroll

bars appeared. Then the user would need to

scroll the list down one or more items. When the plot control was then resized

large enough to fit all legend items, the list would still be scrolled and the scroll

buttons would disappear.

3. Added missing WordWrap checkbox in the iLabel property editor.

4. Fixed the Plot axis Master-UI-Input issue that caused other axes to not respond

to mouse-wheel movements.

5. Fixed Plot Annotation bug that would occur when the X-Axis was in DateTime

mode. There was an error in the span pixels calculation for the width of the

annotation.

6. Fixed PlotAnnotation OuterMargin being ignored when the style property is set

to ipasTextBox and multi-line text is displayed.

7. Fixed issue with the plot control axis labeling where when in the Prefix mode,

the 0.0 value tick label would show up as 2.78f (0.000000000000278) due to

floating point storage/rounding issues. The new code detects this rounding

issue and displays a hard-coded "0.0" string.

8. Fixed bug on the iXYPlot control data-cursor that would result in small

inaccuracies with the returned X&Y values.

9. Fixed bug with Instrumentation controls that support saving strings properties

to file and contained multi-line text. The symptoms would be when reloading

the properties, multi-line string properties would only load the first line and all

other lines would be dropped.

10. Fixed OnPositionOverMax and OnPositionUnderMin event not firing on

Position/Scale type components.

11. Fixed resource leak in iLedRound control. Would result in a HRGN object

being leaked each time the Led was drawn.

12. Fixed ALT key trapping problem on all controls in the ActiveX version.

New Features:

1. Added SpanMinimum, MaxMargin, and MinMargin properties to the axes

Tracking features. Use SpanMinimum to limit the minimum value for the Span.

Use the MaxMargin and MinMargin properties to provide a margin above or

below the data. These properties are also used when performing a ZoomToFit

operation.

2. Added the ResetStartTimeOnFirstDataPoint property to the iPlotChannel

object. This property is useful if you are adding data with an elapsed time using

the AddYElapsedTime or AddYElapsedSeconds methods and you want the

first data-point to start at zero.

3. Added AllowOutOfOrderXValues and DrawOutOfOrderXValues properties to

the Plot control Channel type (iPlotChannel for VCL and iPlotChannelX for

ActiveX). The iPlotChannel is designed assuming that the X-Values are

incremental. This allows for high-speed drawing of the channel data using the y

= f(x) formula. For a default plot control setup, you will not receive an error if

you add data-points with an out-of-order X-Value. Set the

AllowOutOfOrderXValues property to False so that an exception is raised

when an out-of-order X-Value is added. If you need to have out-of-order x-

values, set the DrawOutOfOrderXValues property to True, but you will loose

the high-speed drawing optimization capability.

4. Added the following events to the Plot control...

OnMouseWheelXAxis

OnMouseWheelYAxis

OnMouseWheelDataView

OnMouseWheelLegend

OnMouseWheelChannel

OnMouseWheelLimit

OnMouseWheelDataCursor

OnMouseWheelAnnotation

5. Added a CanFocus property to the follow plot sub-objects...

XAxis

YAxis

DataView

Legend

Channel

Limit

DataCursor

Annotation

6. Added ClickRectLeft, ClickRectRight, ClickRectTop, and ClickRectBottom

properties to the iPlotAnnotation object (All properties are in pixels). These

properties where added to allow you to determine the extents of annotations

like the Text and TextBox which have their extents determined by the Text,

Font, and etc. attributes. These new properties are not calculated until the plot

is repainted. If you need to position another object based on these property

values immediately, you will need to call the ReCalcLayout method to force a

recalculation of all pixel based property values.

7. Added UseCachedInerpolatedData property to the plot control iPlotDataCursor

object. This property is used to speed up calls to the GetInterpolatedYValue

method. When this property is set to False, each call to the

GetInterpolatedYValue method requires a ReCalcLayout method call. If you

are in a loop calling GetInterpolatedYValue many times, performance can

suffer significantly. Typically, this scenario applies when using a curve fitting

interpolation style like Cubic-Spline, Polynomial, and etc. where you want to

iterate over the visible data to get the displayed interpolated values. For this

case, set UseCachedInerpolatedData to True, make any other display settings,

and then call the ReCalcLayout method once before looping and calling

GetInterpolatedYValue. Note: You are restricted to visible data when using this

technique.

8. Added Scalar and Offset properties to all opc-items. Used for scaling and or

applying an offset correction to an opc-item's data. On new opc-data from the

opc-server, the data is multiplied by the scalar before the offset is applied. This

feature is only support on opc data that is of type real or integer. The scalar and

offset is not applied to data with types like Boolean, String, and etc. The

PlotChannel adds an OPCScalar and OPCOffset property that is used for the y-

value. The XYPlotChannel adds an OPCScalar, OPCOffset, OPCScalar2 and

OPCOffset2 property. The OPCItemName, OPCScalar, OPCOffset are used for

the x-value and the OPCItem2Name, OPCScalar2, OPCOffset2 are used for the

Y-value.

9. Added options to allow showing and customization of data-points hints to the

user. Set the channel ShowDataPointHints property to True to allow a hint box

to be shown next to the data-point. The plot must also be the select mode and

the data-point markers must also be visible for this option to be enabled. By

default, the x&y value for the data-point will be shown and will be formatted

using the respective axes labeling formatting. To provide your own formatting,

use the OnDataPointCustomizeHint event and change the AText parameter to

the desired text you want displayed.

10. Added OnMouseDownDataPoint, OnMouseMoveDataPoint, and

OnMouseUpDataPoint events to the plot channel objects. These events will

only fire when the channel is enabled, the plot is in the select mode, and data-

point markers are shown on the channel.

11. Added Image property to the Plot Annotation object. When this property is set

to a non null value, the ImageIndex and ImageListIndex properties are ignored

even if they point to a valid image in one of the three different imagelists. Note:

The Style of the annotation must also be set to "ipasImage" for the image to be

displayed. The lower left pixel of the image is used to set the transparent color

of the image. If you do not want the image to be transparent, make sure to set

this pixel to a color that does not match any other color in the image. You can

also use the new ImageLoadFromFile method to load the image directly from a

file. Also added an ImageClear method to make it easy to clear out the image in

many different ActiveX development environments.

12. Added None to the TiPlotAxesControlStyle which is used by the PlotDataView

AxesControlMouseStyle and AxesControlWheelStyle properties. These new

enumeration allows you to independently turn of the DataView Mouse and

Wheel axes control.

13. Added ability to load the iSwitchLed Glyph property image inside of the

Instrumentation design-time property editor.

14. Added ability to load the iRotationDisplay Picture property image inside of the

Instrumentation design-time property editor.

15. Added property ShowDisabledState to the iSwitchRotary, iSwitchSlider,

iSlider, and iKnob control. This property allows you to control whether the

control draws itself in a disabled state when the Enabled property is set to

False. This feature is helpful when you have background colors that do not

contrast will be disabled text and borders that are drawn using black and gray

colors.

16. Added Image rotation capability to the iObjectCanvas control. Use the

GetObjectImageRotation and SetObjectImageRotation methods on the

iObjectCanvas to Get or Set the rotation of the image object.

17. Added new PlotAnnotation style called ipasRectangle2. The ipasRectangle2

style uses the X, Y, X2, and Y2, properties of the annotation instead of the X,

Y, Width, and Height like on the ipasRectangle style. The main reason for this

addition is to eliminated the wobble in the annotation when resizing it. The

wobble occurs due to aliasing of the mouse movements along with dividing it

evenly into the new Width and or Height value.

18. Added a new property to the PlotAnnotation and PlotLimit called

SelectModeOnlyInteraction. This property is set to true by default meaning that

the plot object will not be mouse interactive will the plot data-view is not in the

select mode. Setting this property to a false will cause the object to be

interactive in any data-view mode (Select, Zoom-box, or Data-Cursor). The

main benefit of this property is to allow these objects to generate mouse-move

events regardless of the mode of the data-view.

19. Upgrade the AngularGauge to hide the last tick label when the

ArcRangeDegrees is set to 360 degrees. Before this upgrade, you would have

the Min label overlapped by the Max label. Only the Min label will now be

shown.

20. Added 2 additional color sections to the iLedBar and iLedSpiral controls. There

are 4 new properties called SectionColor4, SectionColor5, SectionEnd3, and

SectionEnd4. The SectionCount property upper limit has been changed from 3

to 5 to support the two addition color sections.

21. Added VK_APPS key support to plot object pop-up menu support. The pop-up

menu will now pop-up when hitting the menu-list keyboard key.

22. Addded OnAnnotationMoveUser event to the plot controls. This event will fire

anytime the user moves an annotation and the index of the annotation is passed

in the event handler parameters.

23. Addded OnAnnotationResizeUser event to the plot controls. This event will

fire anytime the user moves an annotation and the index of the annotation is

passed in the event handler parameters.

24. Added the following properties, methods, and events which were present on the

Plot control main VCL interface, but were missing on the ActiveX interface...

Properties : PrinterPaperHeightCentimeter, PrinterPaperHeightInches,

PrinterPaperHeightPixels,

PrinterPaperWidthCentimeters, PrinterPaperWidthInches,

PrinterPaperWidthPixels,

PrintXStart, PrintXStop.

Methods : PreviewChart, PrintAdjustXSpanToMinutesPerMillimeter,

PrintSizeToFillPage.

Events : OnBeforePrintPage

25. Add CloseAllServerConnections method to the iOPCManager component. This

method allows you to force all OPCServer connections to close. This method is

useful when the DCOM connection to the OPC server has been lost and you

wish to terminate all connections from the iOPCManger's point of view. After

this method has been called, re-add your opc-items, or call the Activate method

on the existing opc-items have the connect re-established.

26. Added TextLineAlignment property to the plot annotation sub-object. This

property allows you to specify how multiple lines of text are aligned

horizontally in the annotation. Applies to the Text and TextBox style of

annotation.

27. Added the ability for the user to zoom-box while in the scroll/zoom mode by

using the right mouse button. Before, the user had to switch the plot control

into the zoom-box mode to be able zoom into a specific area using the left

mouse button. The user can now perform a zoom-box operation using the right

mouse button while in the scroll/zoom mode. The left mouse button is still used

to scroll/zoom as before. The user must move the mouse more than 5 pixels in

either direction to initiate the zoom-box operation. If the user moves the mouse

less then 5 pixels in either direction while the mouse is down, then releases the

mouse, the pop-up menu will still appear as before.

28. Added the AxesControlAllowInSelectMode property to the Plot Data-View

object. This property allows scrolling and zooming of the plot control while in

the Select mode (Also assuming the AxesControlEnabled property is set to

True). Before, you had to turn off the select mode to be able to scroll or zoom

the view (Also assuming the Zoom-Box mode has not selected). The new right-

click zoom-box mode is supported by this option.

29. Added Visible, BackGroundColor, FontColor, and UseControlFontColor

properties to the Keyboard control button properties. With these properties, you

can hide or customize the look of a specific keyboard button.

30. Added support for adding 2 or more OPC-Items using the same property name

on the control. Typically, this option would be used to control 2 different

digital signal's on the OPC-Server.

31. Added OPCItem2Name, OPCScalar2, and OPCOffset2 properties to the Plot

control channel object. These properties give you the ability to have a separate

OPC item for the X and Y value for each data-point and also to scale and offset

the value. Normally, the OPCItemName property is used to specify the OPC-

Item for the Y-Value and the X-Value is generated based on the

OPCXValueSource property setting. When having the X & Y value sourced

from an OPC-Item, use the OPCItemName property to specify the OPC-Item

for the data-point X-Value and use the OPCItem2Name property to specify the

OPC-Item for the data-point Y-Value.

32. Added ability for the Plot control Label object to support images. Use the

ImageListIndex and ImageIndex property to use an image from one of the 3

internal ImageList's in the plot control. Or use the Image property or

ImageLoadFromFile method to load an image through code dynamically. Use

the ImageClear method to dynamically clear the image. The image will be

centered horizontally using the Alignment property of the label. The

MarginLeft property is used if the Alignment is set to iahLeft. The

MarginRight property is used if the Alignment is set to iahRight. Both the

MarginLeft and MarginRight properties are ignored if the Alignment is set to

iahCneter.


Bug Fixes:

1. Fixed property editor bug that would cause lockups in several different

development environments when click on Color, Font, Picture, and etc. dialogs.

2. Fixed tabbing problems with the ActiveX controls in Visual C++.

3. Fixed OPC Item browsing bug where an Access Violation would occur when

trying to browse more than 512 items in a given branch.

4. Fixed Plot data-cursor bug where delta cursors would always report 0 for the

measured value.

5. Fixed XYPlot data-cursor bug where the data-cursor would always measure the

first channel regardless of what channel was selected.

6. Fixed drawing error bug in the iPhonePad and iKeyBoard control where some

buttons would draw using the disabled control even if they were not disabled.

New Features:

iLinearGauge

Added GetPointersFocused and SetPointersFocused methods.

iLable

Added WordWrap property for multi-line support.

iPlot and iXYPlot

Added OnAddChannel event.

Added OnAddXAxis event.

Added OnAddYAxis event.

Added OnRemoveTable event.

Added OnRemoveAnnotation event.


Bug Fixes:

1. Fixed bug in PieChart and PercentBar where slices less than 1% would not

draw.

2. Fixed name conflict problem with Visual C++ wrapper generator. The

ItemCount property would conflict with the GetItemCount method. changed

GetItemCount method name to Get__ItemCount (note: Get is followed by a

double underscore).

3. Fixed hit test code for all plot objects. Plot objects on the bottom would

respond to the hit-test first. Plot objects on top now respond to the hit-test first.

4. Fixed Zoom-To-fit bug on the PlotAxis class. When the channels assigned to

the axes had no data, calling the ZoomToFit method on the axis would cause

the Span to be set to zero. The ZoomToFit method has been changed to not

modify the Span in this case.

5. Fixed X-Axis label formatting bug that caused the application/process to lock

up. when the Data-Time mode was enabled on the axis and the increment in

labels was in days, months, or years, for some cases, the label generation code

would enter an endless loop causing the application/process to lock up.

6. Fixed clipping problem when printing the plot control with a gradient

background.

7. Fixed bugs on Plot Data-Cursor that would result in a null being displayed if

the pointer was exactly over the first or last data-point in a channel.

8. Fixed Zoom-To-Fit bug on the axes that would occur when all data-points had

the same value. Would result in the application/process locking up.

9. AnalogOutput would always display a "." character for the decimal separator.

No Fixed to use the International settings on the operating system.

10. Fixed iPaintToDC method on all controls to use the correct X & Y offset.

11. Fixed data-cursor problems in displaying the correct values when the axes were

configured for logarithmic display.

Distribution Changes:

The "iOPC.dll" has now been renamed to "iOPC2.dll". The new "iOPC2.dll" has

interface changes to make it compatible with our .Net components/controls. Version 3

SP3 for ActiveX & VCL and Version 3 SP2 for .Net must now use the new iOPC2.dll

during development and distribution. If you have OPC applications developed with

our ActiveX or VCL controls prior to Version 3 SP3, you must still distribute them

with the older "iOPC.dll". It is recommended that both dll's be distributed to the

System32 directory on the client machine and they can coexist together.

prevent correct tracking when the tracking style was set to Expand/Collapse.

3. Fixed bug in table sizing if located on top or bottom of the DataView.

4. Fixed bug in the iPlotAxis Zoom-To-Fit feature that was using non-visible

points to determine the new min and span.

5. Fixed bug in all components that would prevent a window shutdown while the

components were running.

6. Fixed bug in Plot Pack Property editor regarding the addition of labels through

the layout manager. The incorrect label would be loaded when selecting

"Edit..." through the layout manager.

7. Fixed LoadPropertiesFromFile and Save PropertiesFromFile where the

RingBuffer property would be 0 regardless of your current setting or the setting

stored from the SavePropertiesFromFile method when loading the properties

when the channel is set to the FullFeature data style.

8. Fixed bug in iEdit, iAnalogOutput, and iIntegerOutput components that caused

the text displayed to be truncated when the text was wider than the width of the

control. You would be unable to scroll back to edit the text that was not in

view.

9. Fixed DataView gridline bug when using non solid lines. Colored lines would

sometimes be drawn between the dots or dashes.

10. Fixed Plot Pack runtime property editor bug where radio group titles would not

be translated.

11. Fixed bug with ActiveX property editors under the Citect SCADA development

environment where the property editor would lockup when clicking on buttons

when there was a list box on the same property editor tab.

12. Fixed ActiveX bug where SetWindowPos() call in Visual C++ would generate

an exception.

13. Fixed bug in iObjectCanvas where overlapped objects would be misidentified

in the OnClickObject event. The lowest ZOrder object would be identified in

the OnClickObject event as being clicked, even though an object with a higher

ZOrder that overlapped the object.

14. Fixed Plot Pack Data Cursor bug where a hidden hint would still be "clickable",

interfering with selection of the DataCursor line.

New Features:

1. Upgraded Plot Component Compact Interval Data Style to support Ring Buffer.

2. Upgraded Plot Component Compact Interval Data Style to support relocating

the origin X-Value of the Data Set by modifying the DataX[0] property of the

channel. The DataX value of the first data point (i.e. DataX[0]) dictates the

origin of the data set for that channel when using the Compact Interval Data

Style, since the interval between each data point is fixed to save memory

space. Modifying DataX[0], however, doesn't change the fixed interval set

after adding the first two data points. To change the interval, clear the channel

and re-add all channel data.

3. Improved Plot Pack draw performance for multiple Y-Axes.

4. Added DataFile Column Separator property to allow for text tabs or commas.

5. Added DataFile Format property to allow for Text or Compact Interval

(optimized for the Compact Interval Data Type) formatted files.

6. Added OnResize to the TiPlot and TiXYPlot VCL Event Handlers.

7. Added A3, A4, and A5 paper size support to the built-in Plot pack printing

feature.

8. Added ability to change Compact Interval start reference after data has already

been added to the channel by setting the X-Value of the first data point.

9. Added ChannelNameColorStyle to the iPlotLegend object. Allows the channel

name text that is displayed to track other object colors. Possible values are

Font, Channel Color, X-Axis Font Color, or Y-Axis Font Color.

10. Added PointerColor and PointerHighlightColor properties to the iSwitchRotary

and the iSwitchSlider components.

11. Added GetPointersVisible and SetPointersVisible to all Gauge Components.

12. Added to the Plot components two new properties: LastPropertiesFileName,

LastDataFileName and three additional events: OnAfterSaveProperties,

OnAfterLoadData, and OnAfterSaveData. Using these new three events in

addition to the existing event: OnAfterLoadProperties, you can be notified

when the user has saved/loaded data or property files. The two new properties

are useful for determining the filename used during the load or save operation.

13. Updated iImageDisplay to not draw the image as "disabled" when the Enabled

property is set to FALSE.

14. Updated iPlotAxis to include a new ZoomToFitFast method, and a new

TrackingStyle called ExpandCollapseFast. The older ZoomToFit and

ExpandCollapse features would iterate through the entire data set to find the

high and low point of the data when scaling. The new Fast methods use the

RunningXMax, RunningXMin, RunningYMin, and/or RunningYMin methods

of the channel object which cache the historical Max/Min values, thereby

greatly speeding up the ZoomToFit and ExpandCollapse features. Warning: do

not use this new feature if you modify historical data unless you manually call

the appropriate GetXMax/GetXMin or GetYMax/GetYMin functions to force

an update of the corresponding running totals. (e.g. if you modify the Y-value

of a previous data point, you must call GetYMax and GetYMin to update the

"RunningYMax" and "RunningYMin" for the new "Fast" features to work

correctly. ).

15. Updated iPlotLegend with two new properties: ViewStartIndex and

ViewStopIndex. These properties are useful when needing to know the topmost

and bottommost indexes of the visible channels in the Legend. For example, if

you have 100 channels in the chart, and the Legend is currently showing

channel 52-60, then ViewStartIndex=51 and ViewStopIndex=59.

16. Added Transparent and Stretch properties and features to the iImageDisplay

component.

17. Added Stretch property to iRotationDisplay component.

18. Upgraded iSwitchPanel AutoSize to take the height into consideration in

addition to the width when adjusting the KnobRadius property.

19. Added OnClickPointer event hander to the iAngularGauge, iLinearGauge,

iAngularLogGauge, and iLogGauge components. (Not currently supported

under CLX).

20. Added PointerBitmap property and ispsBitmap enumeration to the PointerStyle

property of the iSlider and iSwitchSlider components.

21. Added SetValueNoEvent method, ValueMax property, and ValueMin property

to the iIntegerOutput component.

22. Updated Precision property on the iAnalogDisplay and iAnalogOutput

components to support -1 to indicate the "G" formatting style. The "G"

formatting style will format numbers as the shortest possible string. It will

display the value either as a whole number or exponent, whichever is

shortest. If the precision is unknown at design-time this will ensure that all

digits to the right of the decimal place are shown.

23. Added OnAfterOpenEditor and OnAfterCloseEditor event handlers to the Plot

Pack components to notify when the run-time property editor is opened and

closed.

24. Added an Arc object to the iObjectCanvas component. The following methods

have been added to support this new object type...

AddArc

SetObjectAngles

SetObjectStartAngle

SetObjectStopAngle

GetObjectStartAngle

GetObjectStopAngle

25. Plot Pack iPlotChannel object was updated to support a new interpolation style:

Differential Terminated. This style is the same as the Differential interpolation

style, except there is no line drawn from the last data point out to infinity.

26. Added RotationDesiredSpacing property to the iSwitchRotary

component. Supports 22.5, 45, or 90 degree specification. The desired portion

means that it will only use the angle specified if the "number of positions" *

"desired angle" <= "360 degrees".

27. Added Candlestick option to the iPlot Channel High-Low feature. Below is a

list of new properties added to support this new feature...

HighLowStyle

HighLowShadowColor

HighLowBullishColor

HighLowBearishColor

28. Upgraded iCompass and iDualCompass to allow changing of the direction

captions. Added the following properties...

NCaption

SCaption

ECaption

WCaption

NECaption

NWCaption

SECaption

SWCaption

29. Upgraded Plot Pack Axes labeling to support rotated text. Can be set to 0, 90,

180, and 270 degree rotation.

30. Upgraded iObjectCanvas component to support polygons. Below are the

following methods added to support this feature...

AddPolygon

ObjectAddPolyPoint

ObjectClearPolyPoints

31. Added Print Preview support to the Plot Pack printing feature.

32. Added Plot Pack OnBeforeDataCursorUpdate event. Allows customization of

formatting or other customization before the actual strings are generated for

display on the cursor.

33. Added PNG image support to all components: SaveImageToPNG and

GetBytesPNG methods. Plot pack save dialog updated to support PNG.

34. Added JPEG image support to CLX components under Linux.

35. Added Plot Pack printing support for CLX components under Linux.

36. Added new iOPCManager non-visual component for use in conjunction with

our OPC-enabled components. Allows combining of OPC connections to

servers through a common connection. Previously, each individual component

would make its own connection to the OPC server and its own group. The new

iOPCManager along with the new iOPC.dll improves performance by utilizing

Shared Server Connections and now adds support fro adding groups that can be

shared among OPC Items of our components. The iOPCManager component

has a visual property editor for adding/removing groups as well as properties

and methods that can be used to modify groups at runtime. Two new events,

OnAfterGroupUpdate and OnBeforeGroupUpdate provide notification of

updates that occur among the OPC Items utilizing a particular group.

37. Added multi-line support to the Plot Pack Data Cursor Hint. Use chr(13) for

manual line breaks.

38. Added the following to OPCItems...

ActivateSuspend method

GroupName property

39. Added OPC DeleteItem method for deleting individual OPC Items at runtime.

40. Added new TextBox style (differs from TextRectangle) to Plot Pack

annotations.

41. Added 24 new event handlers to plot pack.

MouseDown

MouseMove

MouseUp

...events for all 8 basic Plot Objects: Channels, X-Axes, Y-Axes, Tables,

DataView, DataCursors, Legend, and Annotations.

42. Added transparency support to Tank.

43. Added three new styles to Tank: Cutout2, Large Window, and Custom.

44. Tank Custom cutout style uses two new methods: CustomPointsAdd,

CustomPointsClear. Use CustomPointsAdd to add at least three points to make

a closed polygon. Added points are in the range of 0-100, representing

percentage (%) of the width and height of the component. It is recommended

to restrict points between 10-90% when the tank is shown.

45. Added vertical and horizontal orientation to Tank.

46. Added scale reverse to Tank.

47. Added OPCActivateSuspend, OPCActive, OPCUpdateSuspend, and

OPCUpdateResume to the iPlot and iXYPlot component Channel objects.

48. Added HitTest method to all Plot Pack sub-objects (channel, y-axis, x-axis,

annotation, label, etc.). Allows you to test each sub-object and determine if an

x/y coordinate exists within the sub-object or not.

49. Added Theme support to the CLX version of the components under both

Windows and Linux.


Bug Fixes:

1. Fixed problem in iPlot and iXYPlot with adding null data points and the ring

buffer. In previous versions if you had enabled the ring-buffer and were adding

null data points to the channel, data would sometimes be corrupted.

2. Fixed bug in iSwitchLED where the accelerator key(& placed before

accelerator key), though it would still function, would not be shown with an

underline but would show the "&" character instead.

3. Fixed several issues with the CLX version of the Instrumentation and Plot Pack

components.

4. Help file corrections. Fixed VCL/CLX help file integration issue with Delphi

and C++ Builder where event help topics would not come up properly in the

object inspector when you press F1.

5. Fixed Plot Pack LoadPropertiesFromFile method where Label objects were not

properly loaded. If you would load properties from a file, you would get a miss

positioned, extra label object than expected.

6. Fixed memory leak in Plot Pack components which would occur only when the

component was destroyed.

7. Fixed border style bug in iPanel component. The border style property would

not properly stream this style property.

8. Fixed font size issues with the CLX component property editors under Linux.

New Features:

1. Added Table support for Plot Pack Components. Allows you to position

custom tables anywhere around the DataView. Allows unlimited number of

rows and columns with individual formatting for each column. Supports

scrolling if the number of rows exceeds the display area. Allows you to specify

the text in each cell.

2. Upgraded iAnalogOutput key-filter to support the current regional setting for

the decimal separator character.

3. Upgraded iLedMatrix indicator caption to support multiple lines of

text. Accepts line feed, carriage return, or both to indicate a break in the line.

4. Added methods and properties for customizing the tick labels on the Plot Pack

Axes. Now supports a custom mode where you can add your own custom

labels (specify the text) at specified locations.

5. Added RecalcLayout to recalculate all coordinates of all Plot sub-objects

without having to wait for the next repaint.

6. Added TransferChannelData method to Plot components to allow transferring

of data from one channel to another. Used to allow easy transfer of basic (Only

X, Y, null, and empty properties. All other data point and channel properties

are not transferred) data from one channel to another. {Appends Data. Need to

clear out destination channel for exact copy}.

7. Upgraded Plot Pack Annotations to support individual clip to axis property.

8. Upgraded LineX and LineY Plot Annotations to extend to the full extent of the

DataView by utilizing the new Annotation-specific clip to axes property.

9. Upgraded iPlot Plot Pack Channel to support High Low graphs/data

points. You must have the Channel Data Style set to Full Feature to utilize this

feature. Added the following methods and properties...

AddHighLow

DataHigh

DataLow

DataOpen

DataClose

HighLowEnabled

HighLowBarColor

HighLowBarWidth

HighLowOpenShow

HighLowOpenColor

HighLowOpenWidth

HighLowOpenHeight

HighLowCloseShow

HighLowCloseColor

HighLowCloseWidth

HighLowCloseHeight

10. Added ForceStacking property to Axes. During normal layout, only touching

ends of stacked axes would take the Stacking End Margin spacing into

account. By setting this property to True, then all axes will use the Stacking

End Margins on all ends. This was done to ensure that outer, stacked axes will

have the same end margins as all axes in the same ZOrder. If this property is

set to False (the default), then the axes will behave as previously indicated.

11. Added PasswordChar property to iEdit to support display of password

characters.

12. Added the following events to all visual ActiveX controls that were missing

them...

OnMouseDown

OnMouseMove

OnMouseUp

OnKeyDown

OnKeyPress

OnKeyUp

13. Added the following events to all visual VCL/CLX controls that were missing

them...

OnMouseDown

OnMouseMove

OnMouseUp

OnKeyDown

OnKeyPress

OnKeyUp

OnEnter

OnExit

14. Added Mouse Wheel Zooming support to the Plot Pack Axes.

15. Added CTRL key support to the Plot Pack Axes and DataView as a NOT

operator to switch between scrolling and zooming when clicking and dragging

the axes.

16. Added SHIFT key support to the Plot Pack. If the MouseStyle (or WheelStyle)

is not set to Both, then the SHIFT key will switch between the X-Axis or Y-

Axis style. If the MouseStyle (or WheelStyle) is set to Both, then the SHIFT

key is ignored. Simultaneous use of both the SHIFT key and CTRL key is

supported.

17. Plot Pack DataView upgraded to support mouse movements and mouse wheel

movements to support scrolling and zooming of the axes. This is similar to the

zooming and scrolling feature in our older iStripChart control. Added the

following properties to the DataView...

AxisControlEnabled (Default = False)

AxisControlMouseStyle (X-Axis, Y-Axis, or Both, Default = Both)

AxisControlWheelStyle (X-Axis, Y-Axis, or Both, Default = X-Axis)

18. Upgraded Right-Clicking Plot Pack code to support right-clicking channel trace

lines to bring up the channel pop-up menu. Supports clicking anywhere on the

trace line and within 10 pixels of the trace line.

19. Added OnXAxisMinSpanChange and OnYAxisMinSpanChange events to iPlot

and iXYPlot.

20. Updated help files for all new properties, methods, and events.

21. Improved HTML help file and Linux HTML help file by removing non-

converted "See Also" links and removing unnecessary double-line breaks.


Bug Fixes:

1. Fixed OptionSaveAllProperties property on Plot Pack components. The

property was previously ignored when saving properties to a file.

2. Fixed ModeComboBox where if you selected an item and then deleted all

items, the ItemIndex property would still point to the deleted item which would

cause errors when accessed.

3. Fixed tabbed-dialog bug in Visual C++ where the application would crash if

one of our components was on the tabbed-dialog and you alt-tabbed to another

application and then back to the Visual C++ application.

4. Fixed Plot Pack bug where if you delete an Axis and then re-add the same type

of Axis, the Channel's associated axis pointer would not reconnect to the new

axis until the next repaint. This would result in functions such as ZoomToFit on

the Axis not working correctly until after a control repaint.

5. Fixed Plot Pack bug where an extra margin would have been incorrectly added

for any plot object placed in-between the DataView and an axis, and that object

had its Visible property set to FALSE.

6. Fixed iXYPlotX Plot Pack ActiveX bug where the Image List and Translations

were not being streamed.

7. Fixed Help File integration into Borland Delphi and Borland C++ Builder

Versions 6 and higher.

8. Fixed bug in Strip Chart where the Auto Scale would malfunction, shifting data

out of view if the AutoScaleHysterisis property was non-zero and AutoScale

was enabled.

Plot Pack New Features:

1. Added the following properties to the Plot Pack Legend object to allow control

of the Legend Column Captions...

CaptionColumnTitle

CaptionColumnXAxisTitle

CaptionColumnYAxisTitle

CaptionColumnXValue

CaptionColumnYValue

CaptionColumnYMax

CaptionColumnYMin

CaptionColumnYMean

2. Added the following methods to the Plot Pack components to allow runtime

clearing and adding images to the built-in image list:

ImageListClear

ImageListLoadFromResourceID

ImageListLoadFromResourceName

3. Added runtime-only property MouseDownHandle to the Object Canvas

component to be used in conjunction with the following existing event handlers

to allow manipulation of objects.

OnMouseDownDisplay

OnMouseMoveDisplay

OnMouseUpDisplay

4. Added Additional Plot Channel Data Style: ipdsFullFeature. This new style

enables extended feature enhancement options of the channel object.

5. Added the following Plot Pack iPlotChannelCustom object (iPlot and iXYPlot)

properties for manipulation of individual data points (when data style is set to

ipdsFullFeature)...

DataMarkerShowing

DataMarkerSize

DataMarkerPenColor

DataMarkerPenStyle

DataMarkerPenWidth

DataMarkerBrushColor

DataMarkerBrushStyle

DataTraceLineColor

DataTraceLineWidth

DataTraceLineStyle

6. Added the following Plot Pack iPlotChannel object (iPlot component only)

properties for manipulation of individual data points (when data style is set to

ipdsFullFeature)...

DataBarVisible

DataBarReference

DataBarWidth

DataBarPenColor

DataBarPenWidth

DataBarPenStyle

DataBarBrushColor

DataBarBrushStyle

7. Updated Plot Pack channel fill routines to support digital channel option as well

as cubic-spline, polynomial, rational, and differential interpolation styles.

8. Updated Plot Pack cursor to support cubic-spline, polynomial, and rational

interpolation styles. Data Cursors already supported digital and differential

interpolation styles.

9. Added Layer Ordering support to all Plot Pack objects. Currently only has an

effect on objects that are displayed in the DataView area (e.g. channels,

annotations, limits, Axes setup as Cartesian, etc,). DataCursors are currently

always forced to the topmost layer and cannot be changed. The highest layer

number are drawn on top of lower layer numbers. If the layer numbers are the

same, then the Instrumentation internal layering order is preserved (i.e. the old

layering order is used from previous versions). By default, all objects are set to

a layer order of 100 for backwards compatibility.

10. Stats page upgraded to clear itself when changing channel objects in the

runtime property editor. It would previously show the previous channel's

information. The page is not refreshed automatically since auto refresh may

cause a performance decrease when refreshing information concerning very

large datasets.

11. Layout Viewer upgrade to support automatic resizing of objects when

attempting to stack using drag and drop. You can simply drag and drop a plot

object on another of the same type to have them proportionally sized and

stacked automatically. Previously you needed to manually size the objects

before you could stack them in the Layout Viewer.

12. Added PrinterName property to the Plot Pack components to specify which

printer to use when using the built-in printing facilities.

13. Upgraded Plot Pack Run-time Property Editor Channel Stats page speed.

14. Added new OnDataCursorCustomizeHint event to the Plot Pack

components.

15. Added FlatButtons and SmallButtons properties to the Plot Pack components

Toolbar object. Provides smaller and/or flat-button-styled buttons in the built-

in toolbar.

16. Upgraded the Plot Pack Layout Viewer in design-time property editor with new

right-click, context sensitive menu to provide add, delete, hide, and show

functions to Layout Viewer Plot Objects.

17. Plot Pack Data Cursor object upgraded to support pointing to all channels in

addition to pointing to individual channels. When pointing to all channels, the

Data Cursor is hidden, and by default, all channel cursor data is displayed in the

Legend. Optionally you can turn off the display of the data in the legend and

display the data in your own legend by reading the data directly from each

channel.

18. Added the following properties to the Plot Pack Data Cursor object...

ChannelAllowAll - Allows the user to specify that the Data Cursor points to

all channels using the popup menu on the Data Cursor.

ChannelShowAllInLegend - Specifies whether the Legend is used to

display the Data Cursor X and Y values when ALL channels have been

selected by the Data Cursor. The X and Y value columns will automatically

be shown if the Legend object and the Data Cursor objects are visible and

the Data Cursor's Channel reference is set to "All", even if the X and Y

columns have been hidden.

19. Added the following new properties to the Plot Pack Channel object for use

with the Data Cursor "All" Channel mode...

DataCursorXText - Read only property that obtains the text that would be

displayed in the data cursor hint for the X-Value.

DataCursorYText - Read only property that obtains the text that would be

displayed in the data cursor hint for the YValue.

DataCursorXValue - Read only property that obtains the numeric value

that would be displayed in the data cursor hint for the X-Value.

DataCursorYValue - Read only property that obtains the numeric value

that would be displayed in the data cursor hint for the Y-Value.

DataCursorStatus - Read only property that specifies whether the X and Y-

Values are valid, null, or empty.

20. Upgraded Plot Pack Legend to support horizontal and vertical

orientation. Upgraded Legend object to support multiple columns, automated

column wrapping and automated scrolling. New properties include...

WrapColDesiredCount - Specifies the number of legend columns to

reserve for the legend. If you specify a value of 3, then three columns will

be reserved even if they are not filled with channel entries. This is useful

when you will be varying the number of channels, but want to keep the

legend at a certain size and specified number of columns.

WrapColAutoCountEnabled - Specifies whether the legend automatically

adjusts the number of columns to take up the least amount of space within

the control. If increasing the number of columns decreases the "footprint" of

the legend, then the legend will automatically increase the number of

displayed columns. After the maximum has been exceeded, then scroll bars

will appear..

WrapColAutoCountMax - Specifies the maximum number of columns

that should be allotted when WrapColAutoCountEnabled is set to

TRUE. This actual number of columns will be equal or less than this value

depending on space requirements and the number and makeup of legend

entries. This property in effect causes the legend to display the scroll bars if

the maximum number of columns is reached, and the number of channel

legend entries exceeds the available space.

WrapColSpacingMin - Specifies the minimum amount of spacing between

legend entries (not the spacing between the channel name, channel X-Value,

channel Data Marker, etc. columns). When WrapColSpacingAuto is

FALSE, then this value is the fixed spacing between columns. When

WrapColSpacingAuto is TRUE, then the spacing will be adjusted to fully

justify the legend entries within the bounds of the legend, but the spacing

will never be less than the minimum spacing specified.

WrapColSpacingAuto - Specifies whether the spacing between the legend

column entries is automatically adjusted by the legend.

WrapRowDesiredCount - Specifies the number of legend rows to reserve

for the legend. If you specify a value of 10, then three rows will be reserved

even if they are not filled with channel entries. This is useful when you will

be varying the number of channels, but want to keep the legend at a certain

size and specified number of rows.

WrapRowAutoCountEnabled - Specifies whether the legend

automatically adjusts the number of rows to take up the least amount of

space within the control. If increasing the number of rows decreases the

"footprint" of the legend, then the legend will automatically increase the

number of displayed rows up to the maximum specified by

WrapRowAutoCountMax. After the maximum has been exceeded, then

scroll bars will appear..

WrapRowAutoCountMax - Specifies the maximum number of rows that

should be allotted when WrapRowAutoCountEnabled is set to TRUE. This

actual number of columns will be equal or less than this value depending on

space requirements and the number and makeup of legend entries. This

property in effect causes the legend to display the scroll bars if the

maximum number of rows is reached, and the number of channel legend

entries exceeds the available space.

WrapRowSpacingMin - Specifies the minimum amount of spacing

between legend entries. When WrapRowSpacingAuto is FALSE, then this

value is the fixed spacing between columns. When WrapColSpacingAuto is

TRUE, then the spacing will be adjusted to fully justify the legend entries

within the bounds of the legend, but the spacing will never be less than the

minimum spacing specified.

WrapRowSpacingAuto - Specifies whether the spacing between the

legend entry rows is automatically adjusted by the legend.

Important New Legend Properties Note and Discussion - Col is used in the

property names to distinguish between the references to Column in other

properties of the legend. When we refer to the property ColumnSpacing or

ColumnTitlesVisible, we are referring to the internal columns of each legend

entry such as "Marker", "Line", "Title" , "X-Value", "Max", "Min", "Mean",

etc.. The properties using "Col" refer to the multiple-column feature that we

have just added where multiple columns of channels (and their associated

displayed information) can be displayed instead of a single column in the

legend. For example, when a legend is horizontal, you will probably have an

average of 5 columns of channels displayed.

This features has also been added in such a way as to be backwards compatible

with previous versions of our Plot Pack components. Therefore, the new

properties above will default to emulate the behavior of the original

legend. However, to take full advantage of the "automated" nature of the new

legend, we recommend that you set the following properties to the following

values. In a future service pack release of Version 3.x, we will set the defaults

to these values, be can't right now due to backwards compatibility concerns...

WrapColDesiredCount = 1

WrapColAutoCountEnabled = True

WrapColAutoCountMax = 3 (for Vertical Legends) or

WrapColAutoCountMax = 100 (for Horizontal Legends)

WrapColSpacingMin = 2

WrapColSpacingAuto = True

WrapRowDesiredCount = 1

WrapRowAutoCountEnabled = True

WrapRowAutoCountMax = 100 (for Vertical Legends) or

WrapRowAutoCountMax = 5 (for Horizontal Legends)

WrapRowSpacingMin = 0.25

WrapRowSpacingAuto = True

21. Added new OPC event handler to all OPC-enabled components:

OnBeforeNewOPCData. This event passes the index of the OPC item and the

variant data value by reference (pointer reference) so that you can modify or

scale the value before it is passed to the component and before the standard

event handlers are called.

22. Added independent Cursor and Legend data point value formatting to the Plot

Pack axis objects. Each channel is associated with a Y-Axis and X-Axis. Each

axis is responsible for specifying the formatting of displayed data for values

associated for that axis. This goes for channel data displayed in other objects,

such as in the cursor and/or legend objects. By default, all objects display X

and Y values formatted as shown in the respective axis. For example, if the X-

Axis is formatted as date/time "hh:nn:ss", then X-values displayed in the Data

Cursor are displayed formatted the same way. You can now override this

default formatting, and specify that the formatting be different when displayed

in either the Legend or Data Cursor Objects. The following new properties in

the X and Y-Axis objects...

CursorUseDefaultFormat

CursorFormatStyle

CursorDateTimeFormat

CursorPrecisionStyle

CursorPrecision

CursorMinLength

CursorMinLengthAutoAdjust

LegendUseDefaultFormat

LegendFormatStyle

LegendDateTimeFormat

LegendPrecisionStyle

LegendPrecision

LegendMinLength

LegendMinLengthAutoAdjust

The following properties serve as the "Default Formatting" for the Legend and

Cursor Objects when the UseDefaultFormat properties are set to TRUE...

LabelsPrecision

LabelsPrecisionStyle

LabelsFormatStyle

DateTimeFormat

LabelsMinLength

LabelsMinLengthAutoAdjust

23. Updated installer to support Delphi 7 VCL and CLX components.

24. Upgraded Plot Pack to correctly display long labels in the X and Y-axes so that

they are not "cropped" when near the edge of the component. This has resulted

in a change in the layout of the plot component objects, particularly the Legend

and Label objects. Now, the Label object and Legend object

top/bottom/left/right margin properties are strictly interpreted. This will result

in the gap between the Legend and the Data View as well as Labels and the

Data View shrinking to be exactly the margin specified by the

top/bottom/left/right margin properties.

Since the default top/bottom/left/right margins for the Legend are set at a

default of one character, the margin between the Data View and the Legend

will now be exactly one character. Since the default top/bottom/left/right

margins for the Label is set at a default of zero characters, the margin between

the Data View and the label will now be exactly 0 characters (plus font specific

kerning). This means that with most fonts, there will be a kerning gap (extra

space added below the baseline to accommodate characters that are generally

drawn below the baseline such as "j" or "g"), but letters that go below the

kerning baseline will now touch the Data View. To fix this, we recommend

setting the margin nearest the Data View to 0.25 characters (or alternatively

setting all margins for all labels to 0.25 characters). This change should not

affect most users in a negative way, but will slightly change the visual layout of

some objects.

25. iObjectCanvas now supports loading images into a built-in image list that can

also stream into your form. You can also load image lists from resources using

name or ID.

26. Added GetDisplayXToPixelsX and GetDisplayYToPixelsY to

iObjectCanvas. Allows conversion between the component's display units and

pixels on the component.

27. Added new iImageDisplay component. Allows loading of multiple bitmap

frames, and controllable animation framerate.

28. Updated Plot Pack component backgrounds to support gradient colors.

29. Added new iPipe component. Includes 3d straight pipe and animation

capabilities.

30. Added new iPipeJoint component. To be used with the iPipe component.

31. Added new iIntegerOutput component. Similar to iAnalogOutput, but supports

Integer only output. Supports Integer, Hex, Binary, and Octal formatting

styles.

32. Added new iScope Component. True Analog/Digital Oscilloscope component

with built-in Trigger.

33. New VCL/CLX, ActiveX WinHelp, and ActiveX HTML Help for MSDN (Pre

January 2002 Edition) Files including many corrections.

34. Added new iLCDMatrix component. Includes 5x7 built-in character font for

displaying 5x7 dot-matrix display text. Also supports loading external

character sets of custom size. Several additional 5x8 character sets are

included. An external font editor is available for download from our website.

35. Added new iMotor component.


Bug Fixes:

1. Fixed "Interface Not Supported" exception in Visual Basic.NET and C#.NET

that occurred with the Plot Pack.

2. Fixed problem where popup dialogs and runtime property editors would block

other threads from accessing the component while they were

visible. Unnecessary Lock and Unlocks by these dialogs were removed.

3. Redesigned the Instrumentation Theme Panel component in the Instrumentation

Design-Time property editors to fix a bug under Windows 95/98/ME operating

systems when applying changes. Nested panel components within the theme

panel were causing conflicts with the Windows API combo boxes that were

used.

4. Redesigned the Instrumentation Theme Panel auto-centering code for

compatibility under CLX.

5. Fixed bug in iModeComboBox VCL component where the OnChange and

OnChangeUser events would not fire under Delphi 4-5 and C++ Builder 4-5.

6. Fixed bug in Plot Pack Annotations when used with logarithmic axes. The

annotation would size logarithmically instead of linearly when doing manual

sizing with the mouse at runtime.

7. Fixed ActiveX compatibility issues with Microsoft Visual

Studio.NET. Components now successfully stream and function with managed

VB.NET and C#.NET applications. ActiveX components already were

compatible with Visual C++ .NET. See the Instrumentation ActiveX Release

Notes for any issues with porting older Visual Basic 5/6 applications to

VB.NET using our ActiveX components.

8. Fixed absolute positioning bug in Internet Explorer. Component would always

be positioned at the origin (upper left-hand corner) of the web page if absolute

positioning was used with our components.

9. Fixed misspelling for default filename in the Plot Pack Save

JPEG/BITMAP/Metafile dialog.

10. Limited DateTime format dates to years between 1400 to 9000. This resolves

zooming errors that occurred when trying to zoom past these limits.

11. Fixed multiple pointer streaming issue in the ActiveX Gauge Components. If

multiple pointers were setup at Design-Time, they would not be streamed

correctly to the form.

12. Fixed problem with Plot Pack zooming when using Logarithmic scales.

13. Fixed Plot Pack Differential Interpolation drawing algorithm problem. The last

data point should draw to infinity. If the last data point went out of view, the

infinity line would incorrectly disappear.

14. Fixed problem where an additional pointer would be added to our gauge

components every time you loaded the project in Visual Basic.

15. Fixed Theme problem where width and height of preview component would be

switched if the orientation of the component was opposite of the default setting.

16. Fixed GetBytesJPEG memory leak and speed issues.

17. Fixed recursive painting bug when using stacked axes in the Plot Pack. This

only became obvious with large, viewable data sets.

18. Fixed OPCItem browser limitation of 256 computers when browsing a

Windows computer domain. The limit has been upgraded to support

approximately 1000 computers per domain when browsing.

19. Fixed bug during development under Windows 95a/b where the component

would appear to be unlicensed. This did not affect deployed applications under

Windows 95a/b, only development.

20. Fixed runtime property editor bug with plot pack when running under large

fonts. Form would not automatically scale properly to large fonts.

21. Fixed memory leak in iKeyboard drawing algorithm.

22. Corrected ActiveX sizing problem in RSView.

23. Fixed iObjectCanvas OnClickObject event. The event handler was not firing

correctly.

New Features:

1. Added to iPlotChannelCustom, DrawStartIndex and DrawStopIndex that

inform you of the data point indexes that are currently visible in the Data View.

2. Added OnBeforeLoadProperties and OnAfterLoadProperties events added to

Plot Pack Components.

3. Added Width, Height, Left, and Top properties for ActiveX containers that do

not provide these properties by default. These properties are specified in

pixels. If the container overrides these properties then the container will be

responsible for these properties. For example, Visual Basic overrides these

properties and replaces them with its own container properties. Its container

properties are specified in Twips by default and not in Pixels.

4. Added UserCanAddRemoveChannels property. This property controls whether

the Add/Remove buttons are shown in the Runtime Property Editor.

5. Added SaveAnnotationsToFile and LoadAnnotationsFromFile methods to the

Plot Pack Components. This method should be called after loading properties

from a file since the loading of properties clears out the entire control.

6. Added ZoomToFit context sensitive menu item and method to the X and Y-

Axis Objects

7. Added OnBeforeZoomBox event to Plot Pack Components.

VCL and CLX Components: Passes two parameters by pointer that you can

modify, ZoomRect and Cancel. ZoomRect has the pixel coordinates of the

zoom box that can be easily converted to Axes values. Cancel allows you to

cancel the Zoom Box if you wish.

ActiveX Components: Passes five parameters by pointer that you can modify,

Left, Right, Top, Bottom, and Cancel. The four coordinate parameters have the

pixel coordinates of the zoom box that can be easily converted to Axes

values. Cancel allows you to cancel the Zoom Box if you wish.

8. Added four new methods to Plot Pack Annotation Object: PositionXToPixels,

PositionYToPixels, PixelsXToPosition, PixelsYToPosition for converting pixel

coordinates to position values.

9. Added one new method to Plot Pack Annotation Object: UserCanSize which

allows the application end-user to resize the rectangle annotation objects.

10. Added two new styles to the Plot Pack Channel Data Marker Styles:

VerticalLine and HorizontalLine.

11. Updated Plot Pack Axes Tracking Style characteristics for

SmoothScroll. Before, this style would only scroll when the new value was

greater than the max of the axis. The new characteristic is to scroll when the

new value is greater than the max or less than the min.

12. Added new event handler to the Plot Pack: OnAnnotationCoordinatesChange

and OnAnnotationCoordinatesChangeFinished events which allows you to

handle changes of the X, Y, X2, Y2, Width, Height, or any other future

position/size property of Annotation. This event is generally used in

conjunction with the UserCanMove and UserCanSize properties which allows

your application end-users to move and size Annotation Objects. The event

will fire from user generated events as well as changes to the position/size of

annotations by your code.

13. Added Bar support to the iPlot component channel object.

14. Added LabelsVisible property to the Axis Objects (X and Y-Axes) of the Plot

Components. This property allows you to hade the axes labels, showing only

the axes tick marks

15. Added the following Grid Line properties to the DataView object of the Plot

Pack:

GridLineXMajorCustom

GridLineXMajorColor

GridLineXMajorWidth

GridLineXMajorStyle

GridLineXMinorCustom

GridLineXMinorColor

GridLineXMinorWidth

GridLineXMinorStyle

GridLineYMajorCustom

GridLineYMajorColor

GridLineYMajorWidth

GridLineYMajorStyle

GridLineYMinorCustom

GridLineYMinorColor

GridLineYMinorWidth

GridLineYMinorStyle

16. Added FocusHandle property to keyboard control. Allows setting the window

handle of the component that will receive keystrokes.

17. All ActiveX components upgraded to include Width, Height, Enabled, and

Visible properties. Non-visible components (such as the timer components) do

not contain these properties. These properties are provided for ActiveX

containers that do not already supply their own version of these properties.

18. Added Image Annotation style. Includes built-in image list for use with

Annotations and other future uses.

19. Added three built-in custom image lists that you can use with Image

Annotations. Images must be loaded at design-time.

20. Upgraded Plot Pack Data Cursor to convert Carriage Return and Line Feed

characters to a single space in the Data Cursor Tool Tip to avoid strange

characters.

21. Added new OPC methods to Instrumentation and Professional Pack

Components.

OPCItemUpdateSuspend which allow deactivation of updates from the server.

OPCItemUpdateResume which allow re-activation of updates from the server

after suspension by using OPCItemUpdateSuspend.

GetOPCItemData

GetOPCItemTimeStamp

GetOPCItemQuality

SetOPCItemData

22. Added new OPC event: OnOPCData which will notify you every time an

update is received from the OPC Server. The standard component events (such

as OnPositionChange in the iKnob control) are only fired when an update that

changes the current component property.

23. Added to MarkersTurnOffLimit iPlotChannelCustom object. This allows you

to suppress the drawing of DataMarkers according to the limit set here. If the

number of DataMarkers to display is greater than this value, all DataMarkers

for the channel will not be drawn. This speeds up drawing operations when

displaying large numbers of data points on the screen.

24. Added CopyToClipBoardFormat property to Plot Pack. Possible selections are

Bitmap, Metafile, and JPEG.

25. Added the following event handlers to the Plot Pack. Each event passes four

parameters: Index of the Object, Cancel Flag By Reference, ScreenX in Pixels,

and ScreenY in Pixels.

OnPopupMenuChannel

OnPopupMenuXAxis

OnPopupMenuYAxis

OnPopupMenuToolBar

OnPopupMenuLegend

OnPopupMenuLimit

OnPopupMenuAnnotation

26. Added Cartesian Coordinate Axes support to the Plot Pack components. Added

three new properties to the Axis objects...

CartesianStyle

CartesianChildRefAxesName

CartesianChildRefValue

27. Updated Plot Pack Digital Channel to support FastDraw.

28. Added new property to Axis object: GridLinesVisible.

29. Upgraded CubicSpline and Interpolation Trace styles to support empty and null

data points. Empty data points will be skipped. Null Data points will generate

a break in the trace line.

30. Added the following new properties and methods to the iPlotChannelCustom

(channel object for all Plot Components)...

DataPointSize - the number of bytes used by each data point added to the chart.

MaxDataPoints - the maximum theoretical number of data points that you can

fit into the chart. For 32-bit Windows, this represents the maximum theoretical

number of data points that will fit into the 2GBprocess memory limitation (

minus the applications' memory footprint) imposed by Windows.

Capacity - the number of data points that have been

MemoryUsed - the currently allocated memory used by the data buffer. This

value is in bytes.

DataStyle - specifies the features available to the data points. The Compact

Style uses 8 bytes per data point, and stores X and Y data point data with

Single Precision. This style loses features regarding individual data marker

styles in exchange for a smaller memory footprint. The Standard Style uses 24

bytes per data point, and stores X and Y data point data with Double

Precision. The Standard Style allows for use of the individual data point data

marker styles. The Full Feature Style has extended features that is open for

future expansion

31. iAnalogOutput, iAnalogDisplay, and iEdit have the following properties

added...

ErrorActive - When True, then the following three properties control the

display of the error drawn on the control.

ErrorFont

ErrorText

ErrorBackgroundColor

32. Added GetOPCItemActive to the ActiveX components.

33. Added AutoError to the OPC item. For VCL components, access the OPC item

object to access AutoError. For ActiveX, use the GetOPCItemAutoError and

SetOPCItemAutoError methods. If AutoError is True, then if the quality of the

OPC data received from the OPC Server is not good, then the ErrorActive

property of the component will be set to True. If the OPC Server data is good,

then the ErrorActive property of the component will be set to False. When the

OPC item is connected to the server, and AutoError is set to True, the

ErrorActive property is automatically set to True indicating that the component

is in an invalid state.

34. Optimized LoadDataFromFile method in the Plot Pack to be 500% faster than

previous versions.

35. Optimized Code for speed on Data, Axis, and FastDraw features of the Plot

Pack.

36. Added Compact Interval data type to Plot Pack. This style allows for the

storage of single-precision fixed x-interval data points resulting in the ability to

store approximately 538 million data points total in the chart (this represents

the 2GB limit of applications running under Windows. This value depends on

memory usage in other parts of your application, and the physical and virtual

memory of your computer).

37. Upgraded iEdit and iAnalogOutput to inherit from our own custom

iEditCustom control. Since these controls no longer inherit from the Windows

API or QT API Edit-box control, they no longer have the bugs and

inconsistencies that come along with the API controls.

38. Upgraded iModeComboBox control to inherit from our own custom combo

box control. Since this control no longer inherits from the Windows API or QT

API combo-box control, it no longer has the bugs and inconsistencies that come

along with the API control.

39. Added new TextRectangle Annotation style to the Plot Pack

components. Allows the display of a text string inside of a sizeable rectangle.

40. Added AddXYArray method to Plot Pack Channel object. Allows the addition

of 2-dimensional Variant Arrays to Channel that contain X and Y coordinate

data.

41. Limits upgraded to support streaming.

42. Annotations now clip to axes. Beneficial when you have stacked axes and you

don't want annotations dragging or bleeding into other axis regions.

43. Added PrintDocumentName property to Plot Pack components to specify the

name of the document that is displayed on compatible printers when the chart is

being printed.


Bug Fixes:

1. Fixed Plot Pack problem where a call to ClearAllElements method of the Limit

objects would not result in the component being repainted.

2. Fixed OPC problem where the initial callback would sometimes be ignored

during connection to an OPC server and would only affect static data on the

OPC server.

3. Fixed problem where the Legend Y-Value would incorrectly display the X-

Value column data.

4. Fixed ActiveX bug where license errors would occur if you were not logged in

as Administrator on a Windows NT4/2000/XP workstation at Design-

Time. Does not affect Run-Time.

5. Fixed iKeyboard problem where SecondRowMargin property was ignored

during the automatic height calculations of individual keys.

6. Fixed Plot Pack Interface memory leak. When Plot Pack sub object interfaces

were released, the connection point object was not released resulting in a

memory leak.

7. Fixed rounding error in iOdometer. Values would sometimes be incorrectly

rounded due to differences in floating point calculation results from different

processor manufacturer and models.

8. Fixed AddLimit property of gauge components. Pointer Size and Pointer

Margin properties were reversed. No interface change, only correction of

incorrect property assignment.

9. Fixed Limit events that were not functional in gauge components

10. Fixed OnPositionChange event that was not functional in gauge components.

11. Fixed Data Cursor "Divide By Zero" error in Plot Pack which would occur with

tightly packed data points (multiple data points that would fit into a single

pixel).

12. Fixed ActiveX ZOrder problem in Excel where the ZOrder would not be

preserved from last save.

13. Fixed transparency problems with iKnob, iSwitchLever, iCompass,

iSlidingScale, and iSlidingCompass components that utilize gradients.

14. Fixed resizing issues in RSView and Microsoft Word. Components would

change size when switching between design-time and run-time.

15. Fixed AddLimit method in gauge components. Pointer Size and Pointer

Margin parameters were flipped.

16. Fixed limit events in Gauge components; events were not firing.

17. Fixed OnPositionChange event in Gauges, event was not firing.

18. Fixed the over/under-range triangles in the Seven Segment

components. Would not display over/under-range triangles unless value was 1

above or below the max and min displayable range.

19. Fixed ActiveX painting corruption in iThermometer, iLinearGauge,

iLogGauge, iSlidingScale, and iSlidingCompass when switching between

horizontal and vertical orientations.

20. Fixed decay feature in iSpectrumDisplay component. Decay had not been

functioning since Service Pack 2.

21. Fixed iOdometer visual rotation "blip" problem when TenthsDigitCount = 0.

22. Fixed SavePropertiesToFile method in Plot Pack. Would previously only save

one cursor even if you had multiple cursors in the chart.

23. Fixed OnPositionChange property. Would not fire if changed by an OPC

Server.

24. Fixed HP VEE/Agilent VEE compatibility problem. Plot Pack Mouse events

were blocked by VEE during high CPU load. Symptom: Axis would continue

to move once mouse was released if there was a large CPU load.

New Features:

1. Added iEdit component with OPC string support.

2. Improved OPC browser panel. Browsing for computers is now hierarchical

according to domain. Included look-ahead feature on OPC items to see if sub

items exist below each item in the visible list.

3. Plot Pack now supports OPC connections to channels objects.

4. Keyboard upgraded to support Numeric Keypad style.

5. Add SelectActive property to Plot Pack Toolbar interface. This property allows

background feature.

9. Added CachedDrawing feature to Property Editor of iLedMatrix

10. Upgraded iSlider and iKnob to only write to an OPC server after a change has

finished (i.e. after the mouse button has been released).

11. Updated 7-Segment Analog to Round values instead of Trunc. This will

synchronize the behavior with our other double-value display

components. Clock components will continue to Trunc double values.

12. Added two new Annotation Reference styles: iprtXChannelYDataView

allowing the annotation's X coordinate to move with the channel and the Y

coordinate to be fixed to the DataView and iprtXDataViewYChannel, allowing

for the annotation's X coordinate to be fixed to the DataView and the Y

coordinate to move with the channel.


Bug Fixes:

1. Fixed Internet Explorer error where the visible, width, and height properties

would no longer function in VBScript.

2. Fixed iSwitchLed and iThermometer property editor bugs under ActiveX

which were preventing the property editors from allowing the user to hit the

OK button or to navigate to development environment specific property editor

tabs.

3. Fixed bug in Plot Pack Data Cursors where clicking on one cursor would cause

all other data cursors to be assigned to the same channel.

4. Fixed problem when using MoveWindow in Visual Basic to move component

causes components to redraw incorrectly. Usually happened when component

was moved off the form and then back onto the form. Components would

appear to disappear in some situations.

5. Several issues regarding resizing, moving, disappearing components, and IE

display issues have been fixed in our ActiveX components.

6. Increased compatibility of moving and resizing ActiveX components in

ActiveX containers.

7. Fixed Themes lockup bug in Visual Basic running under Windows 95/98/ME.

8. Fixed OPC where some servers would callback to the component after the

event handlers for the OPC connection were disconnected.

9. Fixed problem where legend would not display existing channels if removed

and then re-added.

10. Fixed legend up/down button scrolling issue.

11. Fixed problem where translations would not persist (stream out).

12. Fixed problem in iAngularGauge where If SectionEnd is less than PositionMin

then the entire section would be filled with that section's color.

13. Fixed OPC Boolean property support. Now supports strings "TRUE" and

"FALSE" (case insensitive) that come from OPC Servers.

New Features:

1. Added Axis Linking Support in Plot Pack.

2. Added FocusControl support to the iLabel component for VCL applications.

3. Added GetBytesJPEG method for use in obtaining a JPEG image for use in

Microsoft IIS server ASP web pages to all component except for iTimers,

4. Added multiple Label support to Plot Pack. Title properties depreciated in favor

of multiple Label support, but are provided for backwards compatibility.

5. Added multiple pointer support to iAngularGauge, iLinearGauge,

iAngularLogGauge, and iLogGauge. Original position and other pointer

specific properties provided for single-pointer applications and backwards

compatibility.

6. Added LoadPropertiesFromFile and SavePropertiesToFile methods to all

components except for TiTimers and TiThreadTimers. Allows streaming of

component properties to a text file for later retrieval.

11. Added CLX component versions of all of our components for use with Delphi

6 for Windows and Kylix 1-2 for Linux.

12. Improved OPC property editor dialog to remember the previous Computer

Name, OPC Server Name, and Update Rate for quicker setup of multiple items.

13. Added Mouse Wheel support to the Knob, Slider, Switch Slider, and Switch

Rotary components. Uses the KeyPageStepSize property to respond to Mouse

Wheel scrolls.

14. Added OnMouseDownDisplay, OnMouseMoveDisplay, and

OnMouseUpDisplay events to the Object Canvas to provide similar events to

OnMouseDown, OnMouseMove, and OnMouseUp but providing the Cartesian

coordinates of the Mouse instead of Pixel coordinates.

15. Added GetPixelsXToDisplayX and GetPixelsYToDisplayY methods to provide

a mechanism to convert between the 0,0 upper-left-hand corner pixel

coordinates provided by the Windows API or QT API and the Object Canvas'

0,0 Cartesian Coordinates.

16. Added FontColor property to ActiveX interface for the iModeComboBox

component.

17. Added CachedDrawing property to components that use background caching

for improved performance. This property should be left on unless the ActiveX

container doesn't properly support background caching (such as Microsoft

Internet Explorer).

18. Added Mouse Wheel support to iKnob, iSlider, iSwitchSlider, and

iSwitchRotary.

19. Added MouseWheelStepSize property to iKnob and iSlider.

20. Added RunningMin, RunningMax, and RunningMean properties. These

property values are only valid for continuous values. These values are invalid if

you add Null or Empty data points to the channel. If you modify previous data

points, these values will also become invalid, but you can force them to

revalidate by calling the Get method variations of these properties: GetYMax,

GetYMean, and GetYMin methods.

21. Added ChannelNameMaxWidth property to specify the maximum width of the

Channel Name column to allow word wrapping of long channel names.

22. Added New Legend Columns. Use the ShowColumnYMax,

ShowColumnYMin, ShowColumnYMean. These values display the running

Max, Min, and Mean of the channel.

23. Added PositionToPercent and PercentToPosition methods to Plot Pack Axis

objects.

30. Added AutoSelect property to the iAnalogOutput control.

ActiveX and VCL Version 2.0.6 Service Pack 3b

Bug Fixes:

1. Fixed Streaming issue with Font properties on sub objects (e.g. Font property

of Channel, axes, legend, etc.) when using Load Method of the plot component.

Problem existed reading in font sub properties.

2. Fixed LineX and LineY annotation styles would not correctly draw if

ReferenceStyle was set to DataView.

3. If the MinMaxUserCanMove property set to true, the Max pointer would not be

moveable if the Min pointer was not visible in angular gauge.

4. Fixed bug in iSwitchLed resulting in CaptionMargin property having no effect

when CaptionAlignment was set to OppositeSide.

5. Fixed Plot Pack components where zoom box would match the axes title font

color.

6. Fixed LineX annotation bug in Plot Pack where Y and Y2 values would be

swapped.

7. Fixed iSevenSegmentClock issue where control would not properly fire the

countdown event if the clock ran past midnight and would instead start

counting up after reaching 0 and would not fire the event.

8. Fixed iLEDRectangle where text caption would overlap the 3D border margins.

9. Fixed Internet Explorer bug where scrolling our ActiveX controls out of view

would cause unexpected resizing in all web pages or painting problems when

scrolled past another frame.

New Features:

1. ScaleMax and ScaleMin added to Spectrum Display.

2. Knob upgraded to allow turning off keyboard support.

3. Added DataEmpty property, AddXEmpty method to iPlot, AddEmpty method

to iXYPlot, and FastDrawEnabled property.

4. Added cursor keyboard support to Plot Pack components.

5. Added FastDrawEnabled property to Plot Pack components. Speeds up drawing

to screen with large data sets.

6. Added Glyph support to iSwitchLED and border support.

7. Integrated OPC client features into components. Please note that a nominal

distribution fee applies if you utilize the OPC features of our components. OPC

Features are not supported under CLX Applications for Delphi 6 and Kylix 1

for Linux. OPC or OLE for Process Control is a communications standard for

communicating with factory floor automation hardware via the network.

1. Updated Help Files

2. Updated Plot Pack Manual PDF (available

at http://www.Instrumentation.com/documentation)

Plot Pack Updates

1. Fixed memory leak when using Plot Pack component sub objects (ActiveX

only).

2. Fixed error in code where each plot component would create the runtime

property editor when the component is created, and not destroy the runtime

property editor after it was show in the component. The result would be that

each plot component would consume large amounts of system resources. Under

Windows 95/98 systems you could only use 2 plot components, and Windows

NT/2000 systems you could only use 3-4 plot components depending on

system resource use.

3. Fixed problem in runtime property editor. Layout editor would not function

properly if other properties in the runtime property editor were changed.

4. Fixed Visual C++ bug where having more than one plot component on form

causes Visual C++ to give errors when running application. Random access

violations occur when you have opened the property editors.

5. Fixed Datax, DataY, and DataNull properties. They previously had no effect.

6. Added Save to Tab Delimited File support to Plot Components.

7. Added automated logging per component and per channel.

8. Added Mouse Events to Plot Component main interface.

9. Added External Toolbar Support.

10. Added BeginUpdate, EndUpdate, Print, CopytoClipboard, Save,

GetSnapShotPicutre, RepaintAll, Lock, and Unlock methods added to Plot

Pack.

11. Added Date/Time calculator for property editor min and span properties.

http://www.iocomp.com/documentation

12. Added AddDataArray method for adding synchronous data from a one or two

dimensional array.

LoadPropertiesFromFile

Instrumentation and Professional Component Updates

1. iSwitchLed upgraded for word-wrap (New Property WordWrap)

2. Spectrum display upgraded to support setting individual colors for each bar.

3. Angular Gauges now support degree range between 0 and 360 (previously 0 to

355).

4. Phone Pad upgraded to support individually changing captions for each button

to a custom value.

5. Added show property for each button in the Phone Pad component.

6. Spectrum Display streaming problem in Visual Basic fixed. NOTE! The

BarValue property has been removed from the ActiveX interface. If you were

using this property before, use the SetBarValue method instead.

Installation

ActiveX Users

1. If you are upgrading from version 2.x, it is recommended to first install Version

2.x SP7 (or higher), open, modify, and save your existing projects. This step

will ensure that there are no compatibility problems with default component

properties that are changed in this version.

2. Visual C++ users must regenerate wrappers for components in existing projects

to utilize new features/methods.

3. ActiveX CAB files that have been digitally signed by Instrumentation Software

are available for download from our website

at http://www.Instrumentation.com/download.

VCL Users

1. If you are upgrading from version 2.x, it is recommended to first install Version

2.x SP7 (or higher), open, modify, and save your existing projects. This step

will ensure that there are no compatibility problems with default component

properties that are changed in this version.

2. Rebuild Library/Package for changes to take effect. This installer will reinstall

new package files and will automatically recompile the Library/Package for

you. If the automatic recompilation fails, you can manually recompile the

packages.

CLX Users [Delphi 6/7 and C++ Builder 6 for Windows]

1. Our VCL and CLX components are split into two different packages. The

installer will automatically compile and install the packages for you. If the

automatic compile and install fails, you will need to manually compile both

packages to use both the VCL and CLX versions of our components in Delphi

6/7 or C++ Builder 6.

logged in as ROOT. There are known issues with doing anything in

KDE/GNOME/KYLIX while logged in as ROOT. Either log in as a general

user or log in as a user with root privileges when using Kylix.

2. Open a shell and navigate to the folder where you downloaded our Linux

installer. Execute "./setup" file to execute the installer.

3. Follow the wizard in the installer to install our CLX component source code.

You will need the keycodes for your purchased product to complete the

installation.

4. All components are automatically installed into the IDE. Installation is

Complete!

5. Help Files are in the form of a local website, located inside the Instrumentation

Components folder you chose during installation. Use your favorite web

browser to view them.

6. If you have any bug reports or problems, please contact Instrumentation

Support directly or fill out a bug report online.

OPC

OPC deployment licensing is now enforced by our installer. If you previously

purchased an OPC Deployment license, and have not entered the OPC Deployment

License into the keycode manager during installation, you will need to do the

following to properly install the OPC Features...

1. Re-run our installer from the Add/Remove Control Panel

2. Select "Modify", click the NEXT button, and then enter your OPC Distribution

keycode where requested.

3. Continue and complete the installation, asking questions as needed.

4. You do not have to re-compile your Delphi or C++ Builder packages to install

OPC.

If you did not purchase an OPC Deployment license and are using the OPC features of

our components, you will be able to use the OPC features in "evaluation-mode" which

will allow you 10 minutes of OPC communication per run of your application. This

will be indicated by the appearance of "Evaluation" in the OPC property page tab of

our component custom property editors.

A new "iOPC.dll" file will be installed in your Window's System32 folder. This file

contains the OPC features of our components. You can determine if the iOPC.dll is

the Full or Evaluation version by right-clicking and viewing the Version Properties of

the file. The "Description" will contain the words "Instrumentation OPC DLL

(Evaluation)" if you are using the Evaluation Version. This file must be distributed

along with your application and any required OPC core dll's.

Note: Version Service Pack 3 and above must use the iOPC2.dll in order for the

controls to properly use the OPC connectivity features of our controls.

Please refer to the OPC Install Notes located in the Instrumentation Product

Directory. An "OPC Distributables" folder has been provided in the Instrumentation

Product Directory with all files that will need to be distributed to your clients. Also

see the OPC Foundation's website for official distribution packages for the required OPC

core files.
