I want my server to listen, when someone connects to it.. show a msg then close, at the bottom it listens, it even connects but it won't send the msg unless I put a Sleep command or msgbox (anything to make it halt), is it closing the program too fast to send the data or something? anyway to check if the data is sent so I know the exact amount of time to wait before ending the server?

Just enable the closesocket calls again and it should work.

hah, I was using RadASM and had the proc's folded (not collapsed). Thanks for pointing it out.
