外国人用vb写的ftp源代码，相当不错！

采用Microsoft Visual C++编写。界面基于对话框方式。通过对socket类继承实现软件中的服务端类serversocket和客户端类clientsocket。由于将服务端类和客户端类的调用在一个工程中实现，所以一个程序既可以作为服务端也可以作为客户端。代码中加入了基本的错误处理功能。-using Microsoft Visual C preparation. Based on the way the dialog interface. Socket type of software succession to the service changer serversocket and clientsocket changer. Due to the services changer and changer call in a project to achieve, so a procedure can be as server can be used as the client. Code by adding a basic error-handling capabilities.

代理服务器（Proxy Server）软件是一种常用的网络软件，常用于网吧、学校、公司等使用局域网的机构中。代理服务器的功能是接受过个客户端的网络请求，分析请求的内容，从远程的服务器上获取信息后返回给客户计算机。本例实现一个比较简单的HTTP代理服务器程序。-proxy server (Proxy Server) software is a common network software commonly used in Internet cafes, schools, companies use LAN institutions.

The cases to achieve a relatively simple HTTP proxy server.

此程序为外部升级程序(需要主程序的调用),具体代码这里就不罗列了,还是自己看源代码吧.此程序主要的思路是通过读取服务器文件获得升级版本及升级地址,有新版本则下载 如果想做成内部升级程序(在主程序内部自动检测及自动升级),只需要在主程序启动时相关的代码即可,大家不仿试试,主要的思路与这个是差不多的,不同之处是怎么处理主程序的自动关闭与启动问题.-This program is an external upgrade (requires the main program call), the specific code is not listed here, or to look up the source code for it. The main idea of this procedure is obtained by reading the file server upgrade and update address, a new version If you want to get inside is to download the upgrade process (in the main program within the auto-detection and auto-upgrade), just start in the main program code can be related, we do not try to imitate, the main idea and this is about the same, different The Department is how to deal with the main program automatically shut down and startup problems.
