一、引言 Internet客户应用程序是位于用户本地计算机上的网络应用程序,它作为用户访问Internet的接口,在HTTP、FTP、Gopher协议的支持下,从Internet上相应的服务器获取资源。传统的开发Internet客户端应用程序是利用Winsock开发,优点是高效率、独立于具体平台,但要求程序员必须要了解Winsock和TCP/IP的底层细节,这对开发复杂的应用程序带来了一定的难度;而VC++6.0MFC所提供的WinInet类集提供了开发Internet客户应用程序的简便快捷高效的方法,使得
I. INTRODUCTION Internet client application is a web application located on the user’s local computer. It acts as an interface for users to access the Internet and obtains resources from the corresponding server on the Internet with the support of HTTP, FTP and Gopher protocols. The traditional development of Internet client applications is the use of Winsock development, the advantage of high efficiency, independent of the specific platform, but requires programmers must understand the underlying details of Winsock and TCP / IP, which brings certain applications for the development of complex The difficulty; And VC ++ 6.0MFC provides WinInet class set provides an easy and efficient way to develop Internet client applications, making
