[求助]孙鑫多线程聊天程序

2007-11-5 21:07

孙鑫的MFC视频,有个例子是多线程聊天程序,我照视频一步一步打出来的,他的程序可运行,我的就不行。打开附带的例子也不行。
retval=bind(m_socket,(SOCKADDR*)&addrSock,sizeof(SOCKADDR));
    if(SOCKET_ERROR==retval)
        {
                closesocket(m_socket);
                MessageBox("绑定失败");
                return FALSE;
        }
就在这段程序出错,
显示“绑定失败”

程序太长 懒得看了 你检查一下套接字版本,1。1还是2。2 还有就是检查以下是UDP还是TCP的
