1. Introducing VBA Macros
Applications of Spreadsheets
C51BR

2. Automating A Workbook with Macros
A macro enables you to combine multiple commands and keystrokes and execute them as a single command.
If you perform a particular task frequently, creating a macro to use can be time-saving and improves the consistency and accuracy of repetitive procedures.
C51BR

3. Automating A Workbook with Macros
The macro recorder looks at the results of your keystrokes and creates a subroutine in Visual Basic for Applications (VBA) which produces the same results as your keystrokes.
Using a macro, you can execute a sequence of instructions by simply clicking a button, pressing a key combination, or selecting a name from a list box.
C51BR

4. Automating Tasks with Macros
Macros are viewed and edited using the Visual Basic Editor.
fine-tune the macro code
delete lines from incorrect keystrokes
create programs from scratch
C51BR

5. Preparing to Record a Macro
Before you can record a macro, you need to decide what to name the macro and where to store it.
A macro name must start with a letter and can contain numbers, letters and the underscore character – but no spaces!
C51BR

6. Preparing to Record a Macro
You may store your macro
In the current workbook
In a new workbook
In the personal macro workbook so that it is available to use in any existing or future workbook.
You can assign a shortcut key to your macro.
Type a letter in the Shortcut key text box within the Record Macro dialog box.
C51BR

7. Recording a Macro Provide a descriptive one-word name for the macro
Provide a shortcut key for executing the macro quickly
Select a storage location for the macro. Where you store a macro determines its availability to other workbooks
Enter a description specifying the purpose of the macro. Excel 2003 enters a description like this one automatically
C51BR

8. Completing the Record Macro Dialog Box
Select a storage location for the macro. Where you store a macro determines its availability to other workbooks.
C51BR

9. Recording & Playing a Macro
Once you’ve established a name and storage location for your macro, you can begin the recording process.
Once you are recording, just perform the task as you normally would.
When finished, stop recording.
After a macro has been recorded, you can run (or play) it at any time.

11. More About Macros To run a macro using the shortcut key
Press and hold the Control key and press the letter you assigned to the macro.
If your letter is uppercase, you need to press both the control key and the shift key and then press the letter.
To delete a macro, select the macro from the list in the Macro dialog box and click the Delete button.

14. Protecting Yourself From Macro Viruses
Most users will specify the “Medium” security setting if they also have antivirus software installed on their system. If you do not have a virus scanner, consider selecting the High or Very High security
For more information about security settings, trusted publishers, and digital signing, click the Help button in the Title bar

16. Introducing the VBA Environment
Microsoft Visual Basic for Applications (VBA) is the shared and fully integrated macro development environment available in Microsoft Office System 2003.
VBA is itself an independent software program.
VBA provides a subset of the features found in the Microsoft Visual Basic programming language.
Visual Basic creates stand-alone applications
VBA must be run within a host application

29. Working with ActiveX Controls
Formerly known as OLE controls, ActiveX controls are prebuilt, reusable software components that you can use to add interface elements and functionality to your workbooks.
command buttons
drop-down list boxes, etc.
You place these controls directly on a worksheet or display them in a custom user form.
There are thousands of ActiveX controls, produced by Microsoft and third-party developers, that you can take advantage of in Excel 2003.

50. Controlling Your Procedures
One of the greatest benefits of writing your own procedures is the ability to control how, when, and what code executes.
VBA provides several control structures that allow you to test conditions for processing and to perform looping operations, which run the same lines of code repeatedly.
These structures let you work within a dynamic environment, engage the user, and make processing decisions within your code.
