无连接的VC++网络通信 源代码，输入本机端口号、目标端口号、目标机IP地址，可以发送消息，并不建立连接。(Connectionless network communications VC++ source code, enter the local port number, destination port number, destination IP address, you can send a message, does not establish a connection.)

VB开发的IP测试程序，这是在我工作中写的调试程序，在配置文件中只需要写上相应的IP，程序就会循环测试IP地址是否在线，不在线的话就会报警提醒(VB development of IP test program, which is written in my work debugger, just write in the configuration file on the corresponding IP, the program will loop test IP address is online, not online, then it will alarm to remind)

局域网聊天，包含语音和视频，是很好的学习资料，值得大家采纳(LAN chat, including voice and video, is a good learning materials, it is worth to adopt)

Visual C++ 网络编程精选实例。TCP/IP,串口网络通信。配书光盘。(Visual C++ network programming selected examples. TCP/IP, serial network communications. CD-ROM with the book.)

CPing依据ICMP协议实现, 可解析域名和IP, 可设置发包数量,统计丢包率(CPing based on ICMP protocol implementation can resolve domain names and IP, you can set the number of contracting, statistical packet loss rate)

一个完善的升级程序，可供编写自动升级程序模块参考。(A complete update program solution.)

说明：  MFC界面，服务器端可通过TCP socket的链接使client和sever端建立链接，然后可以对客户端的相关文件实现监听功能。并显示在服务器相应位置。(client sever )

服务器与客户端分开的简单聊天程序，对于初学者有很大帮助。(Separate client and server simple chat program, very helpful for beginners.)

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!)

网络抓包与协议分析，实现图形用户界面，能利用原始套接字编程接口（winpcap）进行抓包，能对抓包的内容进行分层显示和各字段数值显示，可对抓包进行过滤，将抓包的内容存入数据库。 (Network packet capture and protocol analysis, graphical user interface, to use raw socket programming interface (winpcap) conducted capture, able to capture and display the contents of each field value hierarchical display, capture can be filtered, The capture of the content stored in the database.)
