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)

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.)

用VC++编写一个简单的基于UDP通信实例！实现了客户端与服务器端的通信源代码！(Using VC++ to write a simple UDP based communication instance! To achieve the client and server-side communication source code! )

聊天程序的源码，对学习socket编程很有帮助。(Chat program source code, useful for learning socket programming.)

VC++流量监控程序，记录选择的接口号，得到接口号为interfaceNumber的接口流量。采用PDH技术对网卡的数据包进行测量，类似360的流量监控工具一样，可以实时观察上网流量的变化，包括上传流量与下载流量。(VC++ traffic monitor, record selection interface number to obtain the interface number of the interface traffic interfaceNumber. Using PDH technology for measuring card packet, similar 360 traffic monitoring tools, real-time observation of changes in Internet traffic, including download and upload traffic flow.)

这份源码可以让大家更清晰的知道编写网络通讯的技巧(This code can let everyone know more clearly written communication network techniques)

说明：  socket的服务器和客户端，实现点对点聊天功能(socket server and client, to achieve point-to-point chat)

自己写的一个http 客户端源代码，供大家学习参考。(http client source code for all to learn)
