Adding a new watch expression
The easiest way to add a watch expression is to highlight the expression in
your code and then drag it to the Watches window. VBA automatically enters
all the correct information for you — you don’t need to do anything but look
at the value. You can also highlight the expression and click the Quick Watch
button on the toolbar. When you use this method, you see a Quick Watch
dialog box that tells you about the new watch expression. Click Add to add
the new watch or click Cancel to change your mind.
Using the Add Watch window
A watch expression might be more complex than a single variable or even an
expression in your code. Look at the first expression shown earlier, in Figure
6-6. This expression doesn’t come from the code — I created it by using the
Add Watch dialog box. The Add Watch dialog box (see Figure 6-7) gives you
full control over the expression. To display the Add Watch dialog box, high-
light any expression in your code, right-click the selection, and then choose
Add Watch from the context menu that appears.
You can modify an expression by changing the content of the Expression
field. For example, as you can see in Figure 6-6, I first highlighted the
FreeSpace
entry in the code and then added the 
CStr
part of the expres-
sion. You can also use the Add Watch dialog box to change the context of a
watch expression. It might help to have access to global variables in every
procedure and not just in the current procedure. A common local variable
could also appear in more than one 
Sub
or 
Function
.
