#include <WinAPIGdi.au3>
_WinAPI_DwmInvalidateIconicBitmaps ( $hWnd )


$hWnd Handle to the window or tab whose bitmaps are being invalidated through this call.

Return Value

Success: 1.

Calling this function causes the Desktop Window Manager (DWM) to invalidate its current bitmaps for the window and request new bitmaps from the window when they are next needed. _WinAPI_DwmInvalidateIconicBitmaps() should not be called frequently.
Doing so can lead to poor performance as new bitmaps are created and retrieved.

This function requires Windows 7 or later.
