实现窗口的构建，directX各个组件的初始化，定时器的创建，幕后缓存区的建立，通过自定义函数createddpla():便建立了一个包含位图的幕后暂存区ddpla[num]供程序使用，createdsbuf():建立一个包含声音数据的次缓存区dsbuf[num],就可以在程序中播放声音了。设置颜色键，用于实现镂空效果。在构造函数中实现背景音乐的播放和背景贴图的翻页。-achieve window Construction, directX various components of the initialization, the timer creation, behind the establishment of buffer zones, through createddpla-defined function () : They established a bitmap contains the behind-the-scenes buffer ddpla [num] procedures for the use, createdsbuf () : voices include the establishment of a data cache sub-district dsbuf [num], we can process the broadcast voices. The use of colored keys, openwork designs for achieving results. Constructors in achieving the background music and background map shows the flip.
