To be honest, the Released Programs sticky is more of a place to post programs that are extremely useful. Or at least, should be, but whatever.
The program's good, albeit a tad simple, but as a training program it's very good. Keep doing stuff like this, it helps your coding a lot.
I'm looking into learning .NET, since I haven't tried it yet, so I can't tell exactly how simple it is to make, but yeah.
Just a random question, what's the linecount of the program?
