When do I need it? If you wish to use regular expressions in Visual Basic 5.0, 6.0 or VBA as if they were built in the language, you need RegExpr.

How do I learn them? We have written a tutorial in the help file. You may also read the introduction.

Can I just use VB's built-in Like and Replace? Sure you can - if you're happy with the features they support. Regular expressions are much more. They can search for all character combinations, allow "Or" rules, verify the number of character occurrences, and support zero-width concepts such as word boundaries, end-of-line and "not followed by".
