大致思路说说，就是在外部SRAM里面做了一个大数组[320][240]做了一帧缓冲，所有屏幕相关操作都是在这一帧上面实现的，使用DMA直接丢数据到FSMC接口上，比I/O快多了，然后就是资源的去背问题，所有的图片都是我从手机版上面截图下来的，然后背景色都是0X4DF9，然后因为jpg转换软件的关系，蓝色的背景色会有偏差所以直接判断把0x4df9不显示不可行，后来想到可以用RGB颜色来入手，虽然不是0x4df9但是还是蓝色，所以蓝色分量肯定比红色多，所以做了一个阈值判断(Roughly speaking, a large array [320] [240] is made in the external SRAM to do a frame buffer. All screen-related operations are implemented on this frame. Using DMA to drop data directly to the FSMC interface is much faster than I/O. Then it is the problem of resource backtracking. All the pictures are taken from the top of the mobile version, and then the background color is 0X4DF9. Later, because of the relationship between JPG conversion software, the blue background color will be biased, so it is not feasible to directly judge that 0x4df9 is not displayed. Later, I thought that RGB color can be used to start with. Although it is not 0x4df9, it is still blue, so the blue component must be more than red, so I made a threshold judgment, and then it is the transition between scene and scene.)

VC.NET 解压和压缩大文件的例子
VC.NET 解压和压缩大文件的例子，操作方法上可能和现在主流的WinRAR软件有些不一样，先设置好未压缩文件名、压缩后文件名、未解压文件名、解压后文件名方可进行操作。解压后的文件是mdb格式，压缩文件的格式为zip，用现在的Winrar就可以解压打开文件，本源码还是很有参考价值的。
