Visual C++（后面简写为VC）网络编程是指用户使用MFC类库（微软基础类库）在VC编译器中编写程序，以实现网络应用。用户通过VC编程实现的网络软件可以在网络中不同的计算机之间互传文件、图像等信息。本章将向用户介绍基于Windows操作系统的网络编程基础知识，其开发环境是VC。在VC编译器中，使用Windows Socket进行网络程序开发是网络编程中非常重要的一部分。-The Visual C++ (behind abbreviated as VC) network programming user MFC Class Library (Microsoft Foundation Class Library) in VC compiler program to achieve network applications. User through the the VC programming network software between different computers in a network, transfer files, images, and other information. This chapter will introduce the basics of the Windows operating system-based network programming, the development environment is VC. VC compiler, use the Windows Socket network application development is a very important part of network programming.
