本书是着名游戏程序设计类书籍作者André LaMothe的两卷本《Windows游戏编程大师技巧》中的第一卷的第二版。和作者撰写的其他畅销书一样，在书中随处可见许多有趣但又有一定难度的源程序。作者循循善诱地从程序设计的角度介绍了在Windows环境下进行游戏开发所需的全部知识，包括Win32编程以及DirectX中所有主要组件（包括DirectDraw、DirectSound、DirectInput和DirectMusic）。书中还用单独的章节详细讲授了2D图形学和光栅化技术、游戏算法、多线程编程、文本游戏和解析、人工智能（包括模糊逻辑、神经网络和遗传算法）、物理建模（完全碰撞反应、动量传递和正反向运动学）及实时模拟等游戏程序开发中的关键技术。光盘上带有两套完整的在线电子版书籍，内容涉及General 3D图形和算法以及Direct3D直接模式；此外，还有大量其他特约作者所着的关于游戏编程内容的文章。
光盘内容：
·本书中所有程序的代码，还包括一个新的16位引擎
·关于Direct3D和General 3D的文章和在线书籍
·通用游戏编程工具以及3D引擎的评定版本
·免费素材
·完整的Microsoft DirectX SDK
·Microsoft Visual C++入门版

300多m的是本书带的光盘内容。网上只找到第一版书的中文pdf，第二版是英文chm格式

Programming Windows 5th Edition Book/CD Package

作者简介：

Charles Petzold 从1984年开始编写个人计算机程序，从1985年开始编写Micrososft Windows程序。他在《Microsoft Systems Journal》1986年12月号上发表了第一篇关于Windows程序设计的杂志论文。从1986年到1995年，他为《PC Magazine》撰写“Environments”专栏，给读者介绍了Windows和OS/2程序设计的许多方面。

《Windows程序设计》由微软出版社在1988年首次出版，后来被认为是这方面最好的导论性读本。在1994年5月，Petzold作为仅有的七个人之一（并且是唯一的作家）被《Windows Magazine》和Microsoft公司授予Windows Pioneer奖，以表彰他对Microsoft Windows的成功做出的贡献。

在1999年秋天，微软出版社将出版Charles Petzold 面向普通读者的第一本书。暂时命名为《Code: The Hidden Language of Computer Hardware and Software》，这本书专门介绍数字信息的本质以及计算机处理数字信息的方式。
