用户在使用VC++开发应用程序时，主要有两种方法：调用Windows提供的API函数(Application Programming Interface)和直接使用Microsoft提供的MFC类库(Microsoft Foundation Class)。与MFC相比，API更贴近操作系统，也是每一个Windows程序员必须掌握的。



本文将以一个类似Windows的计算器程序为例，简述Windows API程序设计的方法和一些基本技巧。



思路和算法 -Users in the use of VC++ development and application of procedures, mainly in two ways: call the API function of Windows to provide (Application Programming Interface) and direct the use of Microsoft to provide the MFC class library (Microsoft Foundation Class). MFC compared with, API closer to the operating system, but also every Windows programmers must master. This article will be a calculator program similar to Windows as an example, on Windows API programming methods and some basic skills. Ideas and algorithms
