局域网内的一个简单的聊天程序，分为服务器端与客户端两部分(LAN within a brief chat procedures, divided into server and client part 2)

winsock聊天室(winsock Chat Room)

说明：  监控本地网卡网络流量, 如果有多个网卡, 可分别统计每个网卡的进出网络流量, 并统计总的网络流量.(Monitoring the local LAN network traffic, if there are multiple network cards, network cards can access statistics for each network traffic and overall network traffic statistics.)

raw socket编程，探测网络包。 vc++, win2000测试通过。(raw socket programming, detect network packets. vc++, win2000 test passed.)

说明：  这是非常好的关于网络编程的例子，实现了ping程序，对于学习网络编程的人员来说是非常难得的材料。(It is a very good example of programming on the network to achieve the ping process, for learning network programming staff is very rare material.)

一个监控网卡的程序。功能如果网卡掉线，电脑自动关机(A monitoring procedure for the network card. Function if the network card offline, the computer automatically shuts down)

基于HTTP协议的支持断点续传的下载软件源码(HTTP protocol support for HTTP-based download software source)

TCP端口扫描，可以获得指定IP段内的主机名，mac地址，存活端口，并将这些信息保存在SQLITE数据库，下次可以直接读取数据库信息，移值性好！(CP port scan, you can get within the segment specified IP host name, mac address, survival ports, and the information stored in the SQLITE database, the next can be read directly, transfer value is good!)

说明：  Rip协议实现 仿真器， 技术上包括Qt TableView，UDPSocket。(Emulator Rip protocol implementation, technically, including Qt TableView, UDPSocket.)

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.)
