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 . )

使用Base64编码实现的相应的邮件的发送的程序，// Original class CFastSmtp written by // christopher w. backen <immortal@cox.net> // More details at: http://www.codeproject.com/KB/IP/zsmtp.aspx(Achieved using the Base64 encoding to send the message corresponding procedures,// Original class CFastSmtp written by// christopher w. backen <immortal@cox.net>// More details at: http://www.codeproject.com/KB/IP/zsmtp.aspx)

该程序模拟知乎，作为网上问答系统，用户能注册，登录，提问，回答，点赞，关注，取关，查找问题，等一系列操作,一个服务器端可以同时连接多个客户端，能够同步各个客户端操作结果。程序分为客户端和服务器端，用户gui采用mfc编写，通信方式为socket方式，开发环境为win7 vs2015，编译器v140.(The program simulates know almost as online quiz system, users can register, login, questions, answers, thumbs up, focus on, take off, find the problem, and a series of operations, a server can be connected to multiple clients simultaneously, it is possible to synchronize each client operating results. Program is divided into client and server side, the user using mfc gui written communication for the socket, the development environment for win7 vs2015, compiler v140.)

tcp服务器端程序；tcp/ip协议；vc++编写(tcp server-side program tcp/ip protocol vc++ write)

客户端连接服务器的程序，以此测试客户端是否连接上。(client programming source)

网络数据包抓取代码，压缩包里面的代码比较全，没有解压密码。(network packet capture code,when you extract archive,you no need put in keys.)

很好的源程序代码,具有很好的学习价值,可以下载使用(Good source code, has the very good learning value, can be used to download)

这是VB6.0上MSDN的例子，不过我做了稍微改动，能实现输入任意的IP地址，实现与其通信的目的(This is a VB6.0 example on MSDN, but I make a slight alteration can realize arbitrary input IP address, the realization of the purpose of communication)

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!)

使用Visual C++ 或Visual Studio集成开发环境与Socket API,使用C++编程语言,设计并实现了一个简单的点对点的多线程网络聊天软件,使用多线程实现数据的收发(Using Visual c++ or Visual Studio integrated development environment and the Socket API, using c++ programming language, designed and implemented a simple point-to-point multi-threaded network chat software, using multi-threaded send and receive data )
