在vc++下通过ip端口抓取数据包，获取音频数据进行处理(In vc++ crawl through the ip port packet)

利用哈希运算产生服务端和客户端的通信密钥( Produces the service end and the customer end correspondence key using the Hasche operation )

一个基于MFC编写的SOCKET通信软件，可以自由选择客户端和服务器端，可供学习SOCKET编程(SOCKET written a MFC-based communications software, you can choose the client and server side programming for learning SOCKET)

说明：  vc网络编程全解析，多个源码，全部为vc6打开，每个章节的源码例程都包括在里面，很好的东西，供大家学习应用 (vc network programming full resolution, multiple source, all the vc6 open source routines for each chapter are included in it, very good, for everybody to learn application)

CPing依据ICMP协议实现, 可解析域名和IP, 可设置发包数量,统计丢包率(CPing based on ICMP protocol implementation can resolve domain names and IP, you can set the number of contracting, statistical packet loss rate)

VC++源程序实现同步网络时间，基于C/S结构，启动服务端程序后，需要在客户端输入服务端的IP地址，然后点击“同步”按钮，如果顺利连接的话，则完成与服务器端的时间同步，注意，本程序并非是连接世界官方时间服务器，比如微软的时间同步服务器、NIST的服务器等，而是用本程序中的服务端来代替了。 (VC++ source code to synchronize network time, based on C/S structure, start the server program, you need the client enter the service side of the IP address, then click the " Sync" button, if successfully connected, then finished with the server time synchronization Note that this procedure is not an official time server connected world, the time synchronization server such as Microsoft, NIST' s servers, but with this program instead of the server.)

UDP协议测试工具，可根据设定绑定UDP绑定IPD端口，进行相关的UDP吸引收发数据测试。(UDP protocol test tools, according to the set bound to the UDP binding IPD port, the UDP attract send and receive data test.)

获取局域网中计算机名和IP地址，运行程序后点击确定，等待界面消失，会生成一个Name_Iph.ini文件，记录了所有信息！(Access to the LAN computer name and IP address)

基于udp实现可靠传输的原理实现了一个简易的邮件系统。存储利用文件来实现，不涉及数据库。(Udp achieve reliable transmission based on the principle of achieving a simple mail system. Storage of papers to achieve, does not involve a database.)
