本书介绍了在Microsoft Windows 98、Microsoft Windows NT 4.0和Windows NT 5.0下程序写作的方法。这些程序用C语言编写并使用原始的Windows Application Programming Interface（API）。如在本章稍后所讨论的，这不是写作Windows程序的唯一方法。然而，无论最终您使用什么方式写作程序，了解Windows API都是非常重要的。(This book describes the procedures for writing under Microsoft Windows 98, Microsoft Windows, NT 4, and Windows NT 5. These programs are written in the C language and use the original Windows Application Programming Interface (API). As discussed later in this chapter, this is not the only way to write Windows programs. However, it's important to understand Windows API, regardless of the way you end up writing.)
