I have a picture inside a panel. I have everything working the way I want except I am drawing a rectangle and I need the panel to autoscroll to the location of my rectangle as I draw it. Does anyone have any idea the best way to do this?

Thanks in advance

推荐答案

您可以在内存DC中以完整尺寸绘制它
然后将其区域复制到面板DC :)

You could draw it at full size in a memory DC
and then copy an its region to the panel DC :)
