It was also built into Office applications up to version 2004 for Apple's Mac OS X, other Microsoft applications such as Microsoft MapPoint and Microsoft Visio as well as being at least partially implemented in some other applications such as AutoCAD, WordPerfect and ArcGIS. VBA enables developers to build user defined functions, automate processes, and access Win32 and other low level functionality through DLLs.

If you really want to master RegExp, then I suggest Mastering Regular Expressions, by Friedl.Visual Basic for Applications ( VBA) is an implementation of Microsoft's event-driven programming language Visual Basic 6, and associated integrated development environment (IDE), which is built into most Microsoft Office applications. (For example, the book makes no mention of submatches or 'look ahead'.)

Its descriptions of the various RegExp-related objects, properties, and methods are useful, but are a bit incomplete. I keep the following book at my desk for quick reference on RegExp and other VBScript matters: VBScript in a Nutshell, written by Lomax, Childs, and Petrusha. This site provides a very complete listing of the syntax for RegExp as implemented in VBScript and Jscript: 'Regular Expression Syntax (Scripting)', (VS.85).aspxДЇor general information on VBScript RegExp: 'Microsoft Beefs Up VBScript with Regular Expressions', ДЄnother site for general information: 'An Introduction to Regular Expression with VBScript',

Then, a colon or forward slash followed by zero or more characters of any type (?!) If the input string is '1234, 2345x, 3456', it matches '1234' and '3456'.ДЇor further reading, I recommend the following web sites and books:ДЇor an excellent tutorial on RegExp, including information on the various language-specific implementations, go to: 'Using Regular Expressions with Client Side Scripting', Suppose that, for each entry, you had to extract the site address (e.g., You could use the following pattern, replacing all text matching that pattern with a zero-length string: RegExpFind(MyText, '+(?=)',, False) Returns 'ball', 'ran', 'cheering', 'feel', 'energized'ДЇor another example (based on EE question ), suppose you had the following log entries: Using a wrapper function, this returns an array of the last word in each sentence: In a look ahead, RegExp checks to see whether the look ahead condition is met, but does not include the look ahead in the match that gets returned Then, a 'look ahead' to see if it is followed by a period, exclamation point, or question mark. If you are a Microsoft Office user, you can even use these functions in worksheet formulas for Microsoft Excel or in queries in Microsoft Access. (This article includes a sample Excel workbook that provides examples for each function.) By adding these functions to your VB6/VBA projects, you can quickly and easily incorporate RegExp functionality into your applications. While this article may be most useful to users with intermediate or advanced programming skills, users of all skill levels (beginners included) can benefit from using RegExp by implementing the 'wrapper' functions included in this article. With a little knowledge of the rules and some imagination, you can build incredibly flexible and/or complex patterns. This article provides basic information on the VBScript implementation of RegExp, and how you can use it to gain robust text parsing capabilities in Visual Basic 6 (VB6) and Visual Basic for Applications (VBA) projects. Regular Expressions (RegExp) is a class that offers incredibly powerful text parsing capabilities, in particular allowing users to find (and even replace) substrings within larger text entries that fit a particular pattern.
