Windows Mobile Standard(aka – Smartphone)

Non-touch platform designed for one handed use (I do not agree with this)

• Both are great options for Mobile Messaging

~90% scope of

.NET Framework

• Unit testing support for managed device applications• Same experience as unit testing for desktop

applications• Integrates seamlessly with Team System and Team

Foundation Server• Lets you easily test your application across various

device configurations• Support for Test Execution from Command Line

Unit Testing for Devices

• Device security configuration– Understand and manage device security settings– Export security setting– Create custom security setting

• Manage certificates on the device– View certificates on the device– Add or remove certificates to/from the device

Security Aware IDE

• Build on top of existing core connectivity framework

• Internally used by our own tools (e.g., unit testing)

• Makes it easy to build your own remote tools• Add reference to:

– Microsoft.Smartdevice.Connectivity.dll

Managed Core Connectivity Framework

• Enhancements– Automation support – Access to interfaces via Visual Basic Script– Made it easy to add custom images in the

Device Emulator Manager– XML config file to configure emulator

instances

Mobile UI Challenges

• Screen– Size, orientation, resolution, layout

• Input– SIP, keyboard, dedicated buttons, stylus

• User Interaction– Standing up on a moving bus

• Understand System.Windows.Forms– Compactness– Form and Control classes

• Windows Mobile 2003 SE changed everythingo VGA, Square Screen, Landscape…

• CE Subsystem 4.21 and higher are aware; 4.20 and lower use emulation layer.– HI_RES_AWARE resource can override– Emulation is practical—not beautiful

Display Assumptions - history

• Apps that “assume” anything about the screen size of a device will have problems– Are you ready for high-res, square screen,

and landscape?• Video frame buffers may be non-linear

(direct access)• Emulation may mask some issues

Display Assumptions

• Don’t assume anything• Test on different devices/emulators• Upgrading to .NET Compact Framework 2.0 in Visual Studio

2005 makes you aware by default:

this.AutoScaleDimensions = new System.Drawing.SizeF(96F, 96F);

this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Dpi;

• Take advantage or docking and anchoring and state info (DisplayRotation) for simple needs

Display Assumptions - tips

Screen Layout• Do not try to create non-full screen forms• Top strip• Main Area• Bottom strip

Screen to Form• Top strip

– Don’t hide the title bar– Use the same title in owned forms

• Bottom strip– Don’t use a toolbar control– Don’t use more than two menus– Don’t hide the bottom strip

• Main Area– Place tappable controls near the bottom– TextBoxes or anything requiring the SIP, near the top

Form Basics• Startup• Hiding vs. Closing• Form Navigation• Application Termination

– By User– By platform (!)

• Application.Run• MinimizeBox• Show vs. ShowDialog• Remote Process Viewer• Running Programs List• MobileDevice.Hibernate

Screen-Aware• Size• Orientation• Resolution• UI design per form factor

– What platform am I on?• Patterns & Practices

– Mobile Client Software Factory/Mobile Application Blocks http://www.codeplex.com/smartclient / http://mobile.codeplex.com/

Orientation-Aware control

Demo – Form Basics

• Lifecycle of a form (& app) plus navigation

Handling Input• Keyboard• SIP

– Respond to Show/Hide

• Dedicated Buttons• Stylus or Finger

– Tap– Tap and Hold

• Typically for context menus• Don’t use this!

• InputPanel• HardwareButton• Tap events• Click, MouseDown,

MouseMove, MouseUp

Single-Handed Operation

• Design your app so it can be keyboard driven– Soft keys, D-Pad– Automatically, you are in a good place for

Smartphone

• Besides previous advice...– ...make it finger driven

Learn from Smartphone Model• Entirely Keyboard driven

– D-Pad (Left, Right, Up, Down, Enter)– Good use of Soft Keys are crucial

• Controls are stacked– Label, LinkLabel, CheckBox, ComboBox, TextBox,

DateTimePicker– TabIndex, TabStop

• ...or full screen– ListView, TreeView, DataGrid

Definitions (thanks Wikipedia )

GPS is a satellite navigation systems that provide autonomous geo-spatial positioning with global coverage (one of …) thus allows electronic receivers to determine their location (longitude, latitude, and altitude) to within a few meters using time signals transmitted along a line of sight by radio from satellites. Take Care: Time is accurate but not corrected!

NMEA 0183 (NMEA for short) is a combined electrical and data specification for communication between marine electronic devices such as echo sounder, sonars, anemometer, gyrocompass, autopilot, GPS receivers and many other. It has been defined by, and is controlled by, the U.S.-based National Marine Electronics Association.The standard uses a simple ASCII, serial communications protocol that defines how data is transmitted in a "sentence" from one "talker" to one "listener" at a time.

Windows Mobile & GPSGPS Intermediate Driver provides an intermediate layer that abstracts the actual GPS device from application developers. This intermediate layer also abstracts applications from GPS device manufacturers. Ideally, this enables application developers to write code that works with any GPS hardware, and GPS device manufacturers to produce hardware that works with any application.

FakeGPS (what is, install etc)• Fakes data received by the GPS APIs

– C:\Program Files\Windows Mobile 6 SDK\Tools\GPS• Reads NMEA data

– from \Program Files\FakeGPS\GPSFiles

Or you can do it the hard way:http://www.bbits.co.uk/blog/archive/2006/07/14/12027.aspx

Windows Mobile & GPSProgramming

Did you know that you have all in SDK?Out of the box and ready to use: C:\Program Files\Windows Mobile 6 SDK\Samples\PocketPC\CS\GPS

GPS Sample Classes (http://msdn.microsoft.com/en-us/library/ms881362.aspx)• Gps: The interface to the managed GPS API. use this

class to open, close, and query the device state, and to query the position data from your GPS hardware.

• GpsPosition: Contains the GPS position data received from the GPS hardware.

• GpsDevice: Contains the GPS device state data received from the GPS hardware.

• Utils: Native memory allocation utilities.
