Four In A Row

This is a cool game that i loved to play when i was a bit younger... It's the popular 4 in a row game. I wrote this code because i'm new in vb and need as much expierience as possible! This is a to player game over the internet (uses mswinsock). the code is very very well commented so please give me feedback and credit if you use my code that's all i ask!! Thanx
