Part II: How VBA Works with Excel
Using the Editor tab
Figure 3-5 shows the options accessed by clicking the Editor tab of the
Options dialog box. Use the options in the Editor tab to control how certain
things work in the VBE.
Figure 3-5:
This is the
Editor tab in
the Options
dialog box.
Auto Syntax Check option
The Auto Syntax Check setting determines whether the VBE pops up a dialog
box if it discovers a syntax error while you’re entering your VBA code. The
dialog box tells roughly what the problem is. If you don’t choose this setting,
VBE flags syntax errors by displaying them in a different color from the rest
of the code, and you don’t have to deal with any dialog boxes popping up on
your screen.
I usually keep this setting turned off because I find the dialog boxes annoying
and I can usually figure out what’s wrong with a statement. Before I was a
VBA veteran, I found this assistance quite helpful.
Require Variable Declaration option
If the Require Variable Declaration option is set, VBE inserts the following
statement at the beginning of each new VBA module you insert:
Option Explicit
Changing this setting affects only new modules, not existing modules. If this
statement appears in your module, you must explicitly define each variable
you use. In Chapter 7, I explain why you should develop this habit.
