UDT网络传输协议开源包，是基于UDP的可靠传输协议，支持P2P，有现成的文件传输函数，速度比TCP快。(Open source packages of the UDT network transport protocol is UDP-based reliable transport protocol to support P2P, there is a ready-made file transfer function, the speed is faster than TCP.)

VB开发的IP测试程序，这是在我工作中写的调试程序，在配置文件中只需要写上相应的IP，程序就会循环测试IP地址是否在线，不在线的话就会报警提醒(VB development of IP test program, which is written in my work debugger, just write in the configuration file on the corresponding IP, the program will loop test IP address is online, not online, then it will alarm to remind)

使用vc中的socket类实现的UDP通信程序源码(Using multi-threaded approach to achieve the source code of the UDP traffic)

回声消除代码实例，具有一定的参考价值，可以下载使用。(voice aec code example ,will be valuable to you work if you download it)

这是一个简单地使用WinSock传输文件的工具，分为服务端和客户端，先抛一块砖。(This is a simple way to transfer files using the WinSock tool is divided into server and client, first throw a brick.)

一个基于MFC的网络通信SOCKET程序，实现了接收SOCKET数据的同时，发送SOCKET数据。(An MFC-based network communication SOCKET procedure to achieve the same time to receive SOCKET data, send SOCKET data.)

说明：  MFC实现多线程 简单端口扫描程序 能自定义线程数量及扫描端口范围(MFC simple multi threaded port scanner can scan a custom port number and scope of the thread)

文件异步下载程序vb示例(document asynchronous sample download vb)

这个是我用ghost1.0修改出来源码，框架稳定，对IOCP进行了一定优化，更稳定(This is I with ghost1.0 modify out the source code, stable framework, IOCP, which must be optimized, more stable)

一套完整的在线升级程序，只需修改配置文件即可成为自己的升级程序。(A complete set of online upgrade program, simply modify the configuration file to become their own upgrade process.)
