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.)

说明：  内容拖放的演示, 主要实现列表内容之间的拖放交换(Drag and drop the contents of the demonstration, list the contents of the main drag and drop between the exchange)

说明：  用VB建立透明的窗口，文件名：trans.rar(Using VB to establish a transparent window, the file name: trans.rar)

ffmpeg VC开发库,可以直接配置开发环境进行编译，调试。ffmpeg是个通用解码库。 (ffmpeg VC development libraries)

vb.net中chart的高级用法编程，很漂亮的曲线哦，赶的上LABVIEW的曲线界面。(vb.net how to use chart,beautiful line)

说明：  raised if this happens. These operations are almost always triggered by interrupts, as in Listing 10.5 for the SPI. I provide yet another thermometer as an example in Listing 10.13. This uses the ADC12 in the FG4618 to read the temperature using code from List
