ip helper api简介和源码

一个支持多用户的基于TCP/IP协议的客户/服务器通信的应用程序-a multi-user support based on the TCP/IP protocol client/server communication applications

本程序主要是作为一个客户端，基于TCP/IP协议实现信号的发送！-This procedure is mainly as a client, based on TCP/IP protocol to send the signal!

一个很有用的网络程序，相当于一个邮件服务器，能实现邮件的转发-a very useful network programming, which is equivalent to a mail server, able to forward mail

用WMI实现的对IP地址、DNS的显示和修改。界面上仿照winodws控制面板里的IP设置。-Using WMI to realize IP address, DNS display and modification. Winodws interface modeled on the control panel

这是一个基于VC6.0 CSocket套接字开发的简单文本通信程序，对网络初学者有一定参考价值。-This is a VC6.0 CSocket socket on the development of simple text communications procedures, the network has a certain reference value for beginners.

实现基于SOCKET的网络聊天室功能，适合初学者对网络编程的学习-SOCKET network-based chat room features, suitable for beginners to learn programming on the network

这是一个基于API自己定义的ClientSocket封装基类。-This is an API based on their own definition of ClientSocket Packaging base class.

服务器端通过socket()系统调用创建一个Socket数组后(即设定了接受连接客户的最大数目)，与指定的本地端口绑定bind()，就可以在端口进行侦听listen()。如果有客户端连接请求，则在数组中选择一个空Socket，将客户端地址赋给这个Socket。然后登录成功的客户就可以在服务器上聊天了。-Server-side through the socket () system call to create a Socket after the array (that is set to receive the maximum number of connected customers), with a specified local port to bind bind (), will be able to listen on port listen (). If the client has to connect the request, then select an empty array Socket, the client address assigned to the Socket. And then sign in the success of customers can chat on the server.

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.
