TCP

部署在服务器公网上 实现内外网通讯的源码，外部程序连接到这个程序，这个程序再连接内部服务器(Deployed on the server the public Internet to achieve internal and external network communication)

使用Winsocket API实现的网络通信功能，分客户端和服务器端。(Winsocket API to achieve the use of the network communication function, sub-client and server.)

说明：  一款与CuteFTP软件相媲美的源代码,非常值得下载，学习和参考Ftp工具VC++编程必不可少的源码，学习和使用FTP的朋友不仿下载一看!(A match with the CuteFTP software source code, very worth the download, Ftp tools for learning and reference VC++ Indispensable source programming, learning and use FTP to download the friend does not like a look!)

本程序以动态的方式给对话框加载背景图,给人耳目一新的感觉()

实现本地程序从远程服务器下载文件。保存到本地。同时，具备断点续传的功能。可以在下载一部分的情况下，再次下载从断点处继续下载。(Implement a local program to download files a remote server. Saved locally. At the same time, with the functions of HTTP. You can download a part in the case, once again download continue downloading the breakpoint.)

简易TCP通讯服务器端，QosClt为客户端。多个客户端间的通讯需要基于服务器，即通过服务器转发。(Simple TCP communication server, QosClt for the client. Communication between multiple clients need a server-based, that is transmitted through the server.)

SOCKET编程规范(SOCKET programming specification)

采用syn的扫描方式对一个网段的ip进行扫描，图形界面(Syn scan mode using a segment of ip scanning, graphical interface)
