I feel like the biggest idiot, but why would this work after opening your source? But not work when I create a new project and C/P the EXACT source code. I have textbox1 and everything. But it doesn't work. I don't consider myself a great coder, but this is pissing me off that I can't figure it out. I tried it in .NET 2008 and 2010. I will post my project in a .rar and see if it does the same thing for you. Maybe I just need some sleep or something but I have never felt so stupid.
