VC++内存绘图例子代码，包括了多个实用的VC++函数：比如DrawLine函数：将传入函数的值以图像的形式显示到对应的控件上（int AllNum：总的数据量，int Value[]:数据值数组，COLORREF PenColor：画笔的颜色，CWnd *pWnd:需要显示曲线的控件指针）；DrawWave函数，将传进函数的值以图像的形式显示到对应的控件上；DrawMultiLine函数：将传进函数的值以图像的形式显示到对应的控件上,可以显示多个数据段。-VC++ example code graphics memory, includes a number of practical VC++ function: for example DrawLine function: the value passed to the function is displayed in the form of images to the corresponding controls (int AllNum: the total amount of data, int Value []: Data an array of values, COLORREF PenColor: pen color, CWnd* pWnd: need to show the curve control pointers)　DrawWave function, will pass into the function values are shown in the form of an image to the corresponding controls　DrawMultiLine function: to pass into the function values are shown in the form of an image to the corresponding control, you can display multiple data segments.
