GDI plus help. Deleting an object

[Szhlopp]

If I use GDIplus to draw a rectangle. How do I delete this rectangle? I can use the clear function but it makes the whole screen go black.

Thanks!

If I just want to delete the rectangle. How would I do it?

Yes I can use "EEEEEE" as the background color on a clear. But if I have controls on the forum I have to put my mouse over them again the see them.

I want to be able to functionally call something like this up. And when ever I want be able to just delete it with any controls on the forum not being effected and the background color the same.

#include <gdiplus.au3>
#include <GUIConstants.au3>
;

_GDIPlus_Startup()
$mygui = GUICreate("tester", 400, 400)
$hWnd = WinGetHandle("tester")
GUISetState()
;WinSetTrans($hWnd, "", 50)
$hGraphic = _GDIPlus_GraphicsCreateFromHWND ($hWnd)






$hBrush1 = _GDIPlus_BrushCreateSolid(0xFF999999)
_GDIPlus_GraphicsFillRect($hGraphic, 10, 10, 50, 50, $hBrush1)






while 1 

$msg = GUIGetMsg()

Switch $msg
    
    Case $GUI_EVENT_CLOSE
        Exit
        
EndSwitch




WEnd

A rectangle isn't an object. It's a set of pixels that have been sent to the hardware after some software processing. The only way to delete them is to repaint the area you originally covered.
