UdpClient

一个支持pop3的简单的邮件收发程序(a simple mail procedures)

说明：  vb做的局域网监控系统，同学的毕业设计，研究winsock很有用(vb to do the LAN monitoring system, students graduating from design, research useful winsock)

它是一个c/s网络编程框架，基于对boost.asio的包装（最低在boost-1.49.0上调试过），目的是快速的构建一个c/s系统；效率高、跨平台、完全异步，当然这是从boost.asio继承而来； 自动重连，数据透明传输，自动解决分包粘包问题（这一特性表现得与udp一样）； 只支持tcp和udp协议；(It is a c/s network programming framework, based on boost.asio package (minimum tried to increase the boost-1.49.0), the purpose is to build a fast c/s systems efficient, cross-platform, fully asynchronous, Of course, this is from boost.asio inherited Auto-reconnect, transparent data transmission, automatic sub-stick package to solve the problem (this feature behave the same with udp) Only supports tcp and udp protocol )

基于TCP/IP协议的MFC网络编程实例，适合windows网络编程的初学者(MFC network programming example based on TCP/IP protocol, adaptive for whose who starts to learn Windows network programming.)

程序记录并显示了数据报从源端机器传送到目标机器的过程中所经过的路由器的IP地址，并且记录了数据报到达每个路由器所需要的时间。认真观察到达每个路由器的时间有什么区别，从而熟练掌握traceroute的工作原理和ICMP报文协议。　(The program records and displays the IP addresses of routers through which the datagram sent from the source client machine to the target machine , and the recording of the data packets arrive at the time required by each router . )

一个网络后门程序。演示了通过Http通道的功能穿透安全级别非常高的防火墙，甚至硬件防火墙。()

说明：  一款与CuteFTP软件相媲美的源代码,非常值得下载，学习和参考Ftp工具VC++编程必不可少的源码，学习和使用FTP的朋友不仿下载一看!(A match with the CuteFTP software source code, very worth the download, Ftp tools for learning and reference VC++ Indispensable source programming, learning and use FTP to download the friend does not like a look!)

精通黑客编程光盘代码,适用于新手学习，不要用于非法用途，谢谢合作(CD proficient hackers programming code for beginners to learn, not for illegal purposes, thank you)

又一个使用ICMP.DLL实现ping的小例子 (Another example of using ICMP.DLL to implement ping)
