Use this format for submitting snippets

It may be used later to parse the snippets to a application (like the one in the VB Section)

If you're going to post a snippet in this thread then you should be posting it in the following format:

Snippet Name: ____________________
Keywords: ____,____,____ ...
Description(Optional): _______________________

MessageBox.Show("Did not find " + textToFind + ".");
}

I think I'll make an application that will give these snippets a home; and I think I'll make a DLL that contains them all. With everyone's permission of course.

Snippet Name: Files grouper
