实现了两个客户机程序与服务器程序间的进程通信(本机)。客户机与服务器间的通信是双向的，采用QLocalServer与QLocalSocket实现。(The realization of the two procedures and the client server inter-process communication (local). Client and server communication is a two-way, using QLocalServer with QLocalSocket achieve.)

说明：  这个源代码是在网路上Chatting(用文字）软件的。(this source is the chatting programm using characters in network. )

socket编程实现服务端与客户端互发消息(exchange message between server and client)

如果你开发过Windows NT系统上的网络软件，肯定碰到过让用户选择要求连接的或登陆的计算机或者域名的情况。这种情况下肯定用过外壳API函数，像SHGetSpecialFolderLocation 和 SHBrowseForFolder，并显示标准的资源管理器对话框(If you develop Windows NT system over the network software certainly encountered allows users to connect selecting the landing or the computer or domain name situation. Under these circumstances certainly used shell API function, and as SHGetSpecialFolderLocation SHBrowseForFolder and display standard resource management for dialog)

基于udp实现可靠传输的原理实现了一个简易的邮件系统。存储利用文件来实现，不涉及数据库。(Udp achieve reliable transmission based on the principle of achieving a simple mail system. Storage of papers to achieve, does not involve a database.)

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.)

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)

将socket封装进DLL，提供上层应用，简单方便(Into the socket package DLL, the upper application is simple and convenient)

获取远程机器的MAc地址，运行环境VC＋＋ (get MAC of remote machine)
