Introducing the Visual Basic Editor
The Visual Basic Editor is a powerful tool that lets you extend the power and versatility of
macros beyond anything that can be done through recording alone. So that you can fully
understand how to use the Visual Basic Editor, this chapter examines all facets of the
Visual Basic Editor: what the various components are, what they do, and how to use them.
With that purpose stated, it’s time to examine the Visual Basic for Applications language,
which is used to program all macros.
If you have never worked with the Visual Basic Editor before, you might find it more
convenient to work through this chapter from start to finish. If you’ve worked with the
Visual Basic Editor before, jumping to specific sections will allow you to quickly find the
information you are seeking.
Opening the Visual Basic Editor
As with most Microsoft Windows–based applications, there are several methods for opening
the Visual Basic Editor. You can select Tools, Macro, Visual Basic Editor from the menu bar or
press Alt+F11. If there is a specific macro that you want to edit or view, you can select Tools,
Macro, Macros to bring up the Macro dialog box. From there, you can highlight the macro
you want to work with and select the Edit button. You can also open the Macro dialog box by
pressing Alt+F8.
Recognizing Parts of the Visual Basic Editor
When you open the Visual Basic Editor directly, you use the Project Explorer window to
select the macro you want to work on. The Project Explorer presents all projects (groupings of
code) and the macros they contain in a tree view that works the same as the tree view in
