Hi, since I am not a expert programmer, I need a clear explanation for windows socket programming with Visual C++ 6.0.
I wanna write a program to close the current open ports with VC6.0. I know how to call closesocket() function, but I am not sure how to define the port to close.
Also want to know if there is any difference for the programming codes to close ports between TCP and UDP..
Please let me know some tips. I really aapreciate your help and easy explanations!!

If a port is opened by another process I don't think you can get permission to actually close it. If you are concerned with security then see about getting a firewall.

Closing ports? Maybe you should get a socket tutorial first. (By the way, UDP is a connectionless protocol, you can't close anything but the socket)
