该代码展示了如何利用完成端口配合异步I/O开发可扩展服务端。(The code demonstrates how to complete port with the use of asynchronous I/O can be expanded development of the server.)

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)

用socket编程实现点对点通信，TCP客户端程序，TCP服务器程序，以及UDP点对点聊天通信。(Point to point communication, TCP client, TCP server, and UDP peer chat communication socket programming.)

利用socket实现简单文件传输,mfc实现，很简单(Simple file transfer using socket, mfc achieve)

课程设计自己编写的一个网络抓包软件，MFC界面，并且对包进行分析。很值得学习哦。(Design their own curriculum prepared by a network of ethereal, MFC interface, and the right package for analysis. Oh, very much worth learning.)

Pop3客户端接收信件的整个流程： 1。连接到pop3服务器（默认端口110） 2。发送用户名（user） 3。发送密码（pass） 4。查询当前邮箱状态（stat） 5。查询服务器上所有邮件UID列表（UIDL） 6。查询本地所有邮件的UID列表，从而罗列出新邮件列表（本地UID列表是POP3客户端记录在日志文件中的） 7。对所有新邮件查询其大小（LIST） 8。下载所有新邮件（RETR）利用List提供的邮件大小信息 9。如果有必要，对所有新邮件标志为删除（DELE） 10。结束对话（QUIT） 11。解析本地下载邮件。(Pop3 client receives the entire flow of letters: 1. Connect to the pop3 server (default port 110) 2. Send user name (user) 3. Send password (pass) 4. Query current mail status (stat) 5. Query server UID list of all messages (UIDL) 6. Query local UID list of all messages, which set out the new mailing list (local UID is a POP3 client list recorded in the log file) 7. For all new e-mail inquiries about their size (LIST) 8. Download all new messages (RETR) to use List of information provided by message size 9. If necessary, for all new signs for the delete message (DELE) 10. The end of the dialogue (QUIT) 11. Analysis of local download your mail.)

本程序以动态的方式给对话框加载背景图,给人耳目一新的感觉()

务器端基于select I/O模型。为防止程序界面阻塞，有一个子线程用于不断接收socket并select其中的处理。客户端只有一个线程函数，不过其利用率很高，可用于远程目录交换，请求文件大小，创建若干线程来下载文件。文件传输有上传和下载,还有对等传输，这个项目中，传输文件具体指下载。 (side is based on the Treasury select I/O model. To prevent the program interface obstruction, a son threaded socket for receiving continuous and select which of treatment. Only one client thread function, but its high efficiency, long-distance directory can be used to exchange documents requested size, creating a number of threads to download files. Upload a file transfer and downloading, and the transmission of the project, specifically referring to transfer files downloaded.)

雷达数据采集，日本urg-0.8包，采集2D数据，将雷达测出的长度信号转换成图形数据显示，库包里有C库以及c++库。((Radar data acquisition, Japan urg 0.8 package, 2 d data, the radar to measure the length of the signal into graphic data shows that there are C library and the library of C++ library package.))

类似Windows的netstat程序的程序 (An app which is like to windowss netstat)
