一本非常NB的关于计算机的离散数学与应用书籍！(Discrete Mathematics and its Applications is a focused introduction to the primary themes in a discrete mathematics course, as introduced through extensive applications, expansive discussion, and detailed exercise sets. These themes include mathematical reasoning, combinatorial analysis, discrete structures, algorithmic thinking, and enhanced problem-solving skills through modeling. Its intent is to demonstrate the relevance and practicality of discrete mathematics to all students. The Fifth Edition includes a more thorough and linear presentation of logic, proof types and proof writing, and mathematical reasoning. This enhanced coverage will provide students with a solid understanding of the material as it relates to their immediate field of study and other relevant subjects. The inclusion of applications and examples to key topics has been significantly addressed to add clarity to every subject. True to the Fourth Edition, the text-specific web site supplements the subject matter i)

用VB编写DirectX7.0游戏 　　DirectX7.0终于出现了，同前面DirectX6相同，版本7也带了一个庞大（129M）的SDK开发库，同DirectX6 SDK库相比，DirectX7的SDK库提供了以下新的功能： 　　＊ 对于Visual Basic的支持。用户可以使用类库在Visual Basic环境下开发基于DirectX的程序。 　　＊ 提供更多DirectX3D立即模式（Immediate Mode）下的API函数，以支持DirectX7中新的3D特效，包括立体环境映射、顶点混合等。 　　＊ DirectMusic支持DownLoadable Sound Level 2标准。 　　＊ DirectInput支持8按键的游戏杆设备，同时支持Microsoft的力反馈摇杆。SDK库提供了读取力反馈效果文件的方法。同时提供了Force Editor程序来建立效果。 　　对于VB爱好者来说，新的SDK库终于提供了完整的对VB的支持，现在终于可以使用Visual Basic来编写DirectX的程序了。 (err)
