这是一个关于VC++双缓冲解析的示例源代码，以前经常在论坛上见到不少人在讨论双缓冲的问题，后来自己也在网上找过资料，但感觉有些凌乱，且大多是 DirectX 相关的，没有一个让新手们参考的实例，于是自己做了一个，主要说明双缓冲技术的原理以及双缓冲在 VC++ 的 GDI 绘图环境下的实现方法-This is a double-buffering on the VC++ sample source code analysis, previously often seen many people on the forum discussing the problem of double buffering, and later he himself was looked for information online, but it feels a little messy, and are mostly related to DirectX , there is no reference to an instance of rookies, so own one, mainly to explain the principles of double-buffering and double buffering in GDI VC++ for Implementation of the drawing environment
