SOCKET通信，一个服务端，一个客户端的通信。(SOCKET communications, a server, a client communication.)

通过此程序,可以获得本地计算机的IP地址,并以提示框的形式显示出来.(Through this process, access to the local computer' s IP address, and the form of prompt box is displayed.)

ping工具，基于控制台应用程序，类似cmd的ping功能(ping tools, console-based application)

c++聊天软件客户端代码，可以实现和双方互相聊天，必须客户端后启动(c++ chat software client code)

仿照TCP协议的UDP封装,用ACK，和滑动窗口(Modeled on the TCP protocol UDP encapsulation, with ACK, and sliding window)

获得IP地址和MAC地址的对应关系网络课实验。 根据IP地址发送和接受ARP包获得对应MAC地址。(Access to correspondence between the experimental class network IP address and MAC address. Send and receive ARP packets to obtain the corresponding MAC addresses based on IP addresses.)

广告墙纸.本程序包含一个发布端(把端纸发布到sql server中),客户端会自动读取墙纸,并设置为本机墙纸,还可设置图标排列方式. 目前做为机房的文告发布使用.(Advertising wallpaper.
