Anyone here know C#?

Hi everyone, Im sorry for posting a non flash question on the forum. But Im in a desprate need of help with a C# program Im working on. I spend the whole night searching for something that could help me, but without any sucsess :(. If any anyone here reads this and think they could help me, i would be greatfull if they did :(.

Its about a Regex search and replace functions in a listBox…
It should look like the Ctrl + F search on a webbpage or text file…

Again, Im sorry for posting this **** on this good flash forum :wink:

//Regards Johan
