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)

说明：  MFC实现多线程 简单端口扫描程序 能自定义线程数量及扫描端口范围(MFC simple multi threaded port scanner can scan a custom port number and scope of the thread)

实现单线程文件传输，不支持断点传出，功能相对简单，但是性能很好。(Achieve single-threaded file transfer, does not support breakpoints spread, function is relatively simple, but the performance is very good.)
