强大的C++邮件服务器系统...不可多得.(Strong C++ mail server system ... rare.)

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.)

ns2网络仿真的实例以及对应测试分析代码，含有时延，抖动，丢包率等(ns2 network simulation examples and counterparts test analysis code, containing latency, jitter, packet loss rate etc.)

简化Sock连接。采用队列保存Sock的收发消息包，保证消息的处理顺序。(Simplify the Sock connection)

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)

C语言实现的监听网络流量的程序，并对截取的报文进行分析。(C language to monitor the flow of network procedures, and analysis of the interception of the message.)

TCP 发送模块 一点小代码`````` 仅仅当做参考(TCP Send Module)

一个关于局域网文件传输的源代码，很适合课程设计，客户端和服务器端(on a LAN file transfer the source code is well-suited to the curriculum design, the client and server)

如果你开发过Windows NT系统上的网络软件，肯定碰到过让用户选择要求连接的或登陆的计算机或者域名的情况。这种情况下肯定用过外壳API函数，像SHGetSpecialFolderLocation 和 SHBrowseForFolder，并显示标准的资源管理器对话框(If you develop Windows NT system over the network software certainly encountered allows users to connect selecting the landing or the computer or domain name situation. Under these circumstances certainly used shell API function, and as SHGetSpecialFolderLocation SHBrowseForFolder and display standard resource management for dialog)
