如何做成Office2000的助手窗体,速度要快,拖动时无闪烁，不能及时刷新？

The SetWindowRgn function sets the window region of a window. The window region determines the area within the window where the system permits drawing. The system does not display any portion of a window that lies outside of the window region

int SetWindowRgn(
HWND hWnd, // handle to window whose window region is to be set
HRGN hRgn, // handle to region
BOOL bRedraw // window redraw flag
);
试试吧,自己要做的事很多,如果用的好的话,效果非常不错,拖动没有闪烁.

直接使用Agent控件不行吗？
