First VB project done

[Jaepheth]

Well, I just finished my first Visual Basic program:

http://rapidshare.com/files/219993138/10key.exe.html

It allows you to practice and evaluate 10-key performance.

It's got a lot of room for improvement, and I'm not 100% sure the KSPH is accurate, but I'm itching to move onto more ambitious projects.
