这是完整的一个C/S的客户服务端程序！但是我希望加点功能！请大家帮帮忙，“我要做的是客户端和服务器正常运行的情况下，如果网络断了，（比如说我把网络弄掉了，然后再接好）过了一会网络恢复正常，客户端能自动连接到服务器端，不能人工干涉！ 我查了一些资料，在VC里有一个函数OnTimer(nIDEvent)可以定时产生事件！可以实现这个功能，但是我用了，还是连不上，请大家帮帮忙吧！做好后给我发到我的邮箱里！谢谢！-This is a complete C/S programe,but I hope put more function into it.Please help me.Fllowing is I ll want to do.When client is communicating with server normally,the network link is down. After while the link recovery(ie,I take the cable out from the computer then plug it in.)The Client can reconnect the server automatically not redo by human.I study some reference information to do it.There is a function OnTimer(nIDEvent) in VC can send event message periodically.But I still can t reconnect.Please help me to do it and then mail to me. Thanks.

TCP的客户服务器通信程序 一：程序运行过程 1、运行服务器程序，等待客户端发出请求 2、运行客户端程序，输入客户的IP地址，请求连接 3、若连接成功，服务器端显示客户的IP地址及端口号；客户端接收文件并保存在d:clientls.txt下，否则，显示错误信息。 二：程序实现原理 发送端：打开文件，逐一读取字符到缓冲区（缓冲区大小为1024），若文件大于1024，则成块发送；若小于，则直接发送。 接受端：与发送端同理。-TCP client-server communication program one : running a process, running the server and wait for the client to issue two requests, the client operating procedures, the importation of customer IP address, link request, if successful connection, the server-client shows the IP address and port number ; the client receives the document and preserve d : client ls.txt, otherwise an error message. 2 : Principle procedures transmitter : open the file, read each character to the buffer (buffer size for 1024), and if the document is greater than 1,024, then sent into pieces; If less, then sent directly. Receivers : Send-the same reason.
