外国人用vb写的ftp源代码，相当不错！

一个简单的聊天工具,可以实现多个用户同时上线聊天,目前已实现在局域网可以聊天.这是客户端程序.-A simple chat tool, multiple users can chat on-line at the same time, the current can be realized in the local area network chat. This is the client program.

设定系统网卡各种参数，如ip,dns,相关参数。在2000下立即改变网卡参数。-card system set various parameters, such as ip, dns, the relevant parameters. In 2000 card immediately change parameters.

网络通讯，客户端 VC++ CSocket-network communications, client VC CSocket

example for windows socket UDP.

自用java编制了一个能在局域网中实现internet一样的聊天功能-with java,working out a program whichcan achieve the chat fuction as internet in the LAN.

TCP网络客户端程序-TCP network client

双线程处理Socket，一个线程负责发一个负责 ，TCPDemo在具体实现时，设计了一个CTCPListener类专门用于服务器对特定TCP端口的侦听。另外，设计了一个CStreamSocket类专门用于TCP数据的传输。CStreamSocket作为基类，服务器程序从它派生出另一个类CSocketSender专门用于数据的发送，客户机程序从它派生出CSocketReceiver类专门用于数据的接收。这些类的继承结构如图3

通过消息传递数据,有服务端和客户端-through messaging data, services and clients

局域网内的点对点文件传输,运行前请先关闭防火墙.服务端和客户端要都启动-LAN peer-to-peer file transfer, run before the closure of the firewall. Server-side and client to have to start

一个 完成端口的例子。 结构明晰, 可用在服务端-a complete port example. Clarity structure, available on the server
