利用MFC实现的对话框滚动条设置实例，刷新界面-Implemented using MFC scroll bar to set an instance of the dialog box, refresh interface

我在工作中需要使用一个对话框显示图表，还能进行放大与缩小。图像放大对滚动条CScrollView也进行了处理。-I m working on a dialog to display a type of chart.I figured I could easily find such a thing, or whip one up using the scroll functions of CWnd .
