Macros

And

Visual Basic For Applications

Personal Macro Workbook

• A workbook that opens automatically whenever Excel is opened

• Any macro stored in this workbook can be used by any open workbook

Macro

• Macro storing Excel commands (written in Visual Basic for Applications)

• Visual Basic Editor (VBE) creating, displaying, running, and debugging macro commands

• Project Explorer locating macro modules

• Code window displaying micro statements

Macro Statements

• Sub (subroutine) statement followed by the name of the macro– Defining the beginning of the macro

• Comments begin with apostrophe (’)– Providing documentation

• End Sub statement– Defining the end of the macro

The With Block

• Including With and End With

• Performing multiple actions on the same object

Absolute Cell References

• Referring to a specific cell

• Referred to by cell address or by range name

• Syntax: Range(“A1”).Select– Always selecting cell A1

Relative Cell Reference (I)

• Referring to a cell by its position relative to the active cell

• Offset: giving the position relative to the active cell– First number: indicating the offset in rows

• A positive number: rows below the active cell

– Second number: indicating the offset in columns• A positive number: columns to the right of the active cell

– Offset (2, 3) always refers to a cell two rows below and three columns to the right of the active cell

Relative Cell Reference (2)

• Range: dimensions of cell(s)– Range(“A1”): a single cell– Range(“A1:A3”): a range three rows by one

column

• Syntax: ActiveCell.Offset(2,1).Range(“A1”). Select– Always selecting a single cell two rows below

and one column to the right of the active cell

Data Management Macro

• Automating data list management tasks– Prompting user for input to populate a criteria

range– Filtering list or displaying database functions

based on those criteria

• Use range name for the list or the criteria range

Visual Basic for Applications

• Tool menu, Macro, Visual Basic Editor– Or Alt+F11

• VBA: a subset of Visual Basic

• Macro converted to VBA programs

• Creating macro using macro recorder

• Using Visual Basic Editor to modify

Custom Button – Standard Toolbar

• Creating custom button:• Tools menu, Customize, Command tab, selecting Macro

for the category, dragging custom button to the standard toolbar, selecting Modify Selection button, typing the name to replace “&name button” (do not press enter”, selecting Assign Macro to assign a macro, selecting This Workbook for Micro in, selecting Close

• Deleting a micro and its custom button:– Tools menu, Micro, selecting micro name, clicking Delete button– Dragging the corresponding custom button from the standard

toolbar to the worksheet area

Custom Button – Worksheet

• Creating:– View Menu, Toolbars, Forms, clicking Button tool, drawing a

button, assigning a associated macro, typing the name for the button

• Selecting– Ctrl key and clicking the button (releasing the Ctrl key right

away)• Coping

– Holding Ctrl key and clicking the button (+ sign)• Deleting the macro and its corresponding micro

– Tools menu, Macro, selecting the macro name, clicking Delete button, OK (performing this first)

– Selecting the custom button, right clicking the mouse, selecting Cut

Common VBA statements

• Underscore and ampersand: continuation

• MsgBox statement– Displaying information to the user

• InputBox statement– Accepting information from the user – Storing information in a cell or memory for

future usage in the program

Decision Making• “If-Then-Else-End If” statement• If testing a condition (true or false)• “Then” clause including a series of

commands to execute for the true condition– Then clause is necessity

• “Else” clause including commands to execute for the false condition– Else clause is optional

• Ends with End If statement

Loops

• Do Until -Loop statement– Executing statements repeatedly

• Begin with Do Until statement– Including a true or false condition after the

Until for evaluating

• End with Loop statement• Executing between Do and Loop

statements repeatedly until the condition is true

Points to Remember

• Personal Macro workbook

• Macro

• Visual Basic Editor

• VBA statements– Information: MsgBox and InputBox– Decision making: If – Repeating: Do
