vc C/S结构VC聊天室程序 的源码，感兴趣的可以看看！(vc C/S structure of VC chat program source code, can be of interest to see!)

利用WINSOCK在几台计算机之间互相传输屏幕图象 (WINSOCK use in several computer screen image transmission between)

UDP服务器程序，提供无连接不可靠的数据传输服务(UDP server program that provides connectionless unreliable data transmission service)

程序可以获取本机IP地址，需要先加载Socket库(Program can access the machine IP address, need to load the Socket Library)

ZXPortMap 端口映射源代码 一个很好的端口映射工具(ZXPortMap port mapping source code for a good port mapping tool)

说明：  客户机/服务器模式(Client/Server model)。该模式的建立基于以下两点：1、网络上主机的非对等作用；2、通信完全是异步的。()

实现可靠的UDP封装传输类，可以进行多点传输，采用超时重发机制(Reliable transmission of UDP encapsulation type, can be multi-point transmission, the use of timeout retransmission mechanism)

获得IP地址和MAC地址的对应关系网络课实验。 根据IP地址发送和接受ARP包获得对应MAC地址。(Access to correspondence between the experimental class network IP address and MAC address. Send and receive ARP packets to obtain the corresponding MAC addresses based on IP addresses.)

低电阻测试仪上位机程序，带参数设置功能自动量程、讯响、单次连续、报警上下限设置，及测量数据即时上传功能(Low resistance tester upper computer program, with parameter setting function, automatic range, sound, single continuous, alarm upper and lower settings, and measurement data immediate upload function)

raw socket编程，探测网络包。 vc++, win2000测试通过。(raw socket programming, detect network packets. vc++, win2000 test passed.)
