一个简单的点对点聊天程序，学习socket通讯编程时的练习程序。编译环境为VS2008(A simple peer-to-peer chat program, learning socket communication programming practice procedures. The compiled environment for VS2008)

在局域网内抓取所需要的IP数据包，使用VC++6.0工程编写。(Grab the required IP packets in the LAN.)

端口扫描工具 C++语言编写 代码简洁有效快捷！(Port scanning tool C++ language code is simple and effective and efficient!)

通达信自定义选股插件程序,嵌入通达信，输入某个参数，然后根据相关的股票行情数据计算，然后输出我需要的数据。(Letter custom stock access plug-ins, embedded access to the letter, enter a parameter, and then stocks in accordance with the relevant data, and then output the data I need.)

本代码是利用socket套接字实现点对点的简单聊天软件程序。语言是C++。内附源码，项目设计报告，和可执行文件。(This code is using socket to realize P2P-based simple chatting software. Program lauguage is C++. Besides source code, also Included program design report and executable files.)

vc++ 下的socket收发例程，tcp和udp例程(socket vc++)

这个源码涉及到网络编程，图像处理，数据压缩与传输。(source involved in the programming of the network, image processing, data compression and transmission.)

NAT(Network Address Translators)，网络地址转换：网络地址转换是在IP地址日益缺乏的情况下产生的，它的主要目的就是为了能够地址重用。NAT分为两大类，基本的NAT和NAPT(Network Address/Port Translator)。(The principle and implementation of UDP NAT through P2P )

说明：  关于Socket编程的实例，希望可以给大家提供一定的参考(Socket Programming for example, we hope to provide some reference)

我的毕业设计，一个简单的集聊天，文件传输于一体的vc源码，可选TCP或UDP传输模式！(My graduation project, a simple set chat, file transfer in one vc source, optional TCP or UDP transfer mode!)
