Yes, it should be very similar to the code that you posted originally. Except, the parameters to the socket() call should be changed as you stated.
If you're getting nothing back, you should check the return code from recv. If it's a -1, that indicates an error. For Winsock, I believe WSAGetLastError() should give you the error code.
Well good news...I decided to combind the server and the client together by using multi threading....
i went to get the error code but now it works like it should??? Ill post the code up,
Thank you for your help/replies
