RegEx Builder

Update: February 21st, 2010

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. RegExBuilder is distributed under the Simplified BSD License.

    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.

    Not a big issue because I can run it in sandbox, but a x64 version would be nifty !
    Won’t run on my Win7 x64 as a user or an admin but I fixed the issue running it in a x86 XP VM.
    Thanks

    Jean Pierre, I’m glad you got it working (albeit in a round-about way). I’ve never run x64 OS’s successfully and don’t currently have any installed to debug this problem on. I’m sure that someday I’ll need to do this.

    I tried installing the RegEx Builder and it failed to launch. Tried it on two different XP machines as well as Vista.

    I love this program, but since moving to Windows 7 I can’t use it, it just keeps crashing when I try to load it. It won’t even work in compatibility mode :(

    Hi Erin, I apologize for it not working for you on Windows 7. I’m not entirely sure why not (it’s been working for me on Win7). I played around quite a bit with RegExBuilder today and found a few potential places that might cause problems. I’ve uploaded to new installer to the website. If you want to try this version, I’d sure appreciate knowing if it works for you or not. If not, I’d like to try to figure out what’s wrong.

    BTW: The new version requires .NET 3.5. Hope that’s not a problem.

    Try the latest version 2.0.2.0. I fixed one or two things that might prevent it from launching. However, it’s been working fine for me on both XP and Windows 7 for some time now. If this new version still doesn’t work, let me know.

    Awesome! The new version works on my Win7 installation fine. Thanks! :)

    I just bumped the version to 2.0.2.3 to fix an annoyance where the RegExFolder in the Start Menu could not be moved or renamed without the application recreating the original Start Menu entry the next time it was started.
