定义一个基类MyGraph，要求有一个纯虚函数double Area()=0。从基类派生一个圆类Circle和矩形类Rectangle，再由Rectangle类派生出Square类，分别给出Area()实现。 重载“>>”，实现对图形信息的输入。在主函数中计算三种形状的面积，并显示输出。 (Define a base class MyGraph, requires a pure virtual function double Area () = 0. Derive a circle and a rectangle class Rectangle Circle class from the base class, and then by Square Rectangle class derived class, are given Area () implementation. Reload " > > " to achieve the input of graphical information. Calculate the shape of the three main functions in the area, and display output.)

VC 实现类似迅雷的悬浮窗，精选学习源码，很好的参考资料。(VC suspension window similar to the thunder, select learning source code, a good reference.)

介绍了窗口编程的几种特效显示的方法。比如动态切分，百叶窗等。(Introduction of the window show the effects of several programming approach. For example, dynamic segmentation, blinds and so on.)

说明：  这是一个清理VC工程文件的程序，和其他类似功能的程序不一样的是它只有一个2k的 批处理。 批处理里面演示了批处理文件的一些技巧。包括文件删除，自安装，导入注册表等实现 方法。 (This is a clear VC project documentation procedures, , and other similar functions of the same procedures that it is only one batch of 2k. Batch inside a batch file demonstrated some skills. Including documents deleted, since the installation, etc. into the registry method.)
