VC++网络编程，图形编程实例，初学者可借鉴！-VC network programming, graphical programming examples, beginners can learn!

一个TCP聊天例子

vc实现udp传输实例，属于客户端。-vc achieve udp transmission example, belong to the client.

本程序是使用VC++语言编写的“聊天系统源代码”请站长检查。-this program is to use the VC language "chat system source code" Please check station.

关于TCP，UDP协议的网络编程，程序实现了客户端和服务器端的通信连接，通过socket建立连接，可以互相发送消息接收。-On TCP, UDP network programming protocols, procedures realize the client and server communications connections to establish a connection through the socket, you can send a message to receive each other.

利用MFC实现了Telnet协议,作为Telnet客户端工具,可以连接Telnet服务器.实现技术包括:1,创建Telnet连接.2,从Telnet服务器接收数据.3,向Telnet服务器发送数据.-use of Telnet Protocol, Telnet client as a tool, Telnet server can be connected. Technology include : 1. establish Telnet connection .2. Telnet servers from receiving data .3 to the Telnet server to send data.

代理服务器（Proxy Server）软件是一种常用的网络软件，常用于网吧、学校、公司等使用局域网的机构中。代理服务器的功能是接受过个客户端的网络请求，分析请求的内容，从远程的服务器上获取信息后返回给客户计算机。本例实现一个比较简单的HTTP代理服务器程序。-proxy server (Proxy Server) software is a common network software commonly used in Internet cafes, schools, companies use LAN institutions. Proxy server function is accepted-client network request, analyze the content of the request from the remote server access to the information and returned to the client computer. The cases to achieve a relatively simple HTTP proxy server.
