COleControl::InvalidateControl
Forces the control to redraw itself.
void InvalidateControl(
LPCRECT lpRect = NULL,
BOOL bErase = TRUE
);
Parameters
lpRect
A pointer to the region of the control to be invalidated.bErase
Specifies whether the background within the update region is to be erased when the update region is processed.
Remarks
If lpRect has a NULL value, the entire control will be redrawn. If lpRect is not NULL, this indicates the portion of the control's rectangle that is to be invalidated. In cases where the control has no window, or is currently not active, the rectangle is ignored, and a call is made to the client site's IAdviseSink::OnViewChange member function. Use this function instead of CWnd::InvalidateRect or InvalidateRect.
