Multithread (Client Server) Problem (Repost)

[hkl]

Hi, Can anyone please give me any comment or solution to this situation?? In my program, I've used multithread (many clients) to send message to one thread(Server). However, I realized that only the first client can get access to the server from start to end, other clients are always blocked. Can anyone help me to solve this problem, so that all clients can access the server?? The following is the code of the server: if ( svrSocket.Accept(socket)) AfxMessageBox("Socket is created Succesfully"); while (...) flag = socket.Receive(buff,sizeof(buff)); .... Please HELP! Thank you!!:confused:

If you have the server thread processing the requests for one client in a tight loop, it can't accept other connections. Tim Smith I know what you're thinking punk, you're thinking did he spell check this document? Well, to tell you the truth I kinda forgot myself in all this excitement. But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?

You should probably use CAsyncSocket; it would probably meet your requirements better. Jon Sorry to dissapoint you all with my lack of a witty or poignant signature.

That is because the thread Accept()ing the connection is the same that Receive()s the request on the socket. You must dispatch the socket returned by Accept() first param to another thread, which will Receive(), preventing the server thread from blocking. If you have problem understanding this concept, I suggest that you read this: http://www.codeproject.com/useritems/winsockintro03.asp Michel If I am wrong or said something stupid, I apologize in advance ;)
