这里是我自己学习winsocket2 编程序时候所写的一个聊天室的程序，程序是一步一步完善过来的。 ChartSrv是服务器端 ChartCLient是客户端（可以开多个） 由于里面加入了获取hostname的东西所以速度有点慢，可以注释掉直接使用IP通信就快了。 代码展示了socket2的异步通信的实现，有兴趣的可以一起学习。-Here is my own time learning winsocket2 programmed written by a chat room procedures step by step procedure is to improve overnight. ChartSrv is a server-side ChartCLient the client (can be opened more than) as a result of which joined the hostname to obtain the speed of things so a bit slow, you can comment out the direct use of IP communications on faster. Code demonstrates the socket2 realize asynchronous communication, are interested in learning together.

首先，客户端的日志服务器，网络地址转换分布为本届会议的一个端口60000 ，那么伺服器收到了用户端的地址是202.187.45.3:60000 ，这是外部的客户网络地址。同样，客户乙登入伺服器， B至吨的NAT-First of all, Client A log server, NAT A distribution for the Session of a port 60000, then the Server S received the address of Client A is 202.187.45.3:60000, which is outside of the Client A network address. Likewise, Client B Login Server S, NAT B to the distribution of the Session of the port is 40000, then the Server S received B s address is 187.34.1.56:40000. At this time, Client A and Client B and Server S can be a communication. If Client A at this time would like to direct
