Chapter 11
Automatic Procedures and Events
In This Chapter
▶ Knowing the event types that can trigger an execution
▶ Finding out where to place your event-handler VBA code
▶ Executing a macro when a workbook is opened or closed
▶ Executing a macro when a workbook or worksheet is activated
You have a number of ways to execute a VBA Sub procedure. One way is
to arrange for the Sub to be executed automatically. In this chapter, I
cover the ins and outs of this potentially useful feature, explaining how to set
things up so that a macro is executed automatically when a particular event
occurs. (No, this chapter is not about capital punishment.)
Preparing for the Big Event
What types of events am I talking about here? Good question. An event is
basically something that happens in Excel. Following are a few examples of
the types of events that Excel can deal with:
✓ A workbook is opened or closed.
✓ A window is activated.
✓ A worksheet is activated or deactivated.
✓ Data is entered into a cell or the cell is edited.
✓ A workbook is saved.
✓ A worksheet is calculated.
✓ An object, such as a button, is clicked.
✓ A particular key or key combination is pressed.
✓ A particular time of day occurs.
✓ An error occurs.
