    here is one more doubt of me. How can we broadcast a message actually using MFC socket programing. Is it a for loop and send to each one. Or any syntax is there to broadcast a message to all in a network or may be a set of IP address. I am a beginner

      I think you can but i have never worked with access so i can't help you with it. Plan your chat-protocol carefully, remember that your clients will probably need to be notified of certain events like someone going offline or coming online...

      oh ya that could be also one more problem. I haven't thought about it only. But I guess we can broadcast a special message(going offline) to all. Instead of events notifications. Am I correct? I am a beginner

        what is winsock2? is it for MFC? is there any advantage on normal socket functions like listen/bind/createsocket etc (which I have worked on little bit). I am a beginner

        lol. winsock is called - normal sockets. MFC just wraps around. You will get better understanding if you go for winsock API. I don't force you to leave MFC, but that's not my choice when it comes to sockets. Nishant Shivakumar has a neatly written TCP client server application. I'd recommend you to start with that. wait let me check it.

                thnaks could you please tell me if my design is correct. server ->Maintains a list of Ip_Address-user. Always in listen mode, so that if someone ask for the list it sends it. -> If the admin adds a new user, he will re-send the list to all (but I am not sure, how to do it,when if the clients are busy sending message. should i restart all or do something) client -> on boot/application start, it request server and get the list(His IP-username should be present in the list). And sends a message that he is online to all. ->if he goes offline- he will notify everyone and the go offline. so basically only those people who are listed in the server by admin can only chat

                  Your questions are at times too open & wide. :sigh: Try with simple implementation, once you get the picture you can design your complete application.
