RegEx Builder
Do you need to use regular expression on an occasional basis, but don’t use them enough to become a regular expressions expert. If you answered “yes”, then I have a great solution for you. RegEx Builder is a small utility to help you build regular expressions. Especially useful for those, like me, who don’t use regular expressions everyday, and therefore, don’t always remember all the details. RegEx Builder evaluates your expression as you type so you can see if it is going to match your target text in real-time. No more edit-compile-test loops. RegEx Builder is written in C# using Microsoft Visual Studio 2005 and .NET 2.0.
Features:
- Latest version 2.0.0.0
- Version 2.0.0.0 Adds: Spltter Panels allow for custom control of application panels.
- Version 2.0.0.0 Adds: Regular Expressions can be split to multiple lines for clarity.
- Version 2.0.0.0 Adds: Online Help.
- Simple and intuitive user interface. So simple that only minimal help is provided.
- Live as-you-type evaluation of your regular expression. See your matches in real time.
- Shows all matches in the target text by highlighting each match.
- If you use named matches, RegEx Builder will show you exactly what strings will match the names in your expression.
- Extensive context menu for inserting regular expression constructs into your expression. Just right-click when the mouse is located in the regular expression text box to get a cascading menu of available constructs.

I have been using v1.0.0.6 of RegExBuilder on my Vista machine for some time now without any issues. I’m rebuilding my machine, however, and was excited when I saw there was a new version. However, after installing, I notice that every time I launch the program, Windows tells me that it has stopped responding and I am forced to close it. The only solution to this, is to run the application with Administrator credentials. Why does your app require admin rights?
I’m a bit surprised by that. I don’t run Vista, but I haven’t really added anything between 1.0.0.6 and 2.0.0.0 that would change whether or not it would require Admin rights (obviuusly I did, I’m just not sure what, or why). You’re absolutely correct in assuming that it shouldn’t. The app does nothing that should require admin rights. I’ll look into it.
