基于TCP/IP的网络通信技术实现了面向连接的用户与服务器间点对点异步通信，本代码在该基础上应用了多线程以及共享数据结构技术，使网络服务器具有了多用户间数据转发的功能，进而解决了局域网多用户间的通信问题。 使用时先建立ODBC，Server与ChatServer先运行，然后运行Client- Has realized based on the TCP/IP network communication face between the connection user and the server the point-to-point asynchronous communication, this code has applied multi-thread as well as the sharing construction of data technology in this foundation, enable the network server to have the function which the multiuser between data retransmitted, then has solved the local area network multiuser between correspondence problem. When use first establishes ODBC, Server and ChatServer first moves, then moves Client
