原创 transparentblt

透明位图的显示作者:王骏下载本文示例代码包含透明色的位图的绘制方法有多种，最简单的方法是调用现成的函数：TransparentBlt,也可以通过自己的代码实现类似TransparentBlt的功能，实现过程也有两种形式，一种是事先做一张掩码位图，另一种是动态生成掩码位图。本文将介绍动态生成掩码位图绘制具有透明区域位图的方法。一、TransparentBlt 函数的使用 TransparentBlt

原创队列化消息与非队列化消息 & & Windows消息机制要点

我们已经谈到过，Windows给窗口发送消息，这意味着Windows呼叫窗口消息处理程序。但是，Windows程序也有一个消息循环，它呼叫GetMessage从消息队列中取出消息，并且呼叫DispatchMessage将消息发送给窗口消息处理程序。那么，Windows程序是依次等待消息（类似于普通程序中相同的键盘输入），然后将消息送到某地方去的吗？或者，它是直接从程序外面接收消息的吗？

Creating Games in C++: A Step-by-Step Guide

Do you love video games? Ever wondered if you could create one of your own, with all the bells and whistles? It\'s not as complicated as you\'d think, and you don\'t need to be a math whiz or a programming genius to do it. In fact, everything you need to create your first game, \"Invasion of the Slugwroths,\" is included in this book and CD-ROM. Author David Conger starts at square one, introducing the tools of the trade and all the basic concepts for getting started programming with C++, the language that powers most current commercial games. Plus, he\'s put a wealth of top-notch (and free) tools on the CD-ROM, including the Dev-C++ compiler, linker, and debugger--and his own LlamaWorks2D game engine. Step-by-step instructions and ample illustrations take you through game program structure, integrating sound and music into games, floating-point math, C++ arrays, and much more. Using the sample programs and the source code to run them, you can follow along as you learn. Bio: David Conger has been programming professionally for over 23 years. Along with countless custom business applications, he has written several PC and online games. Conger also worked on graphics firmware for military aircraft, and taught computer science at the university level for four years. Conger has written numerous books on C, C++, and other computer-related topics. He lives in western Washington State and has also published a collection of Indian folk tales.<br>
