GDI+ Clear bitmaps drawed in window

[MrKris1224]

Hi, i'am making small application to my job. I need to draw some icons / bitmaps in another application window. I'am drawing icons by this code:

 

;(...)
$aPos = ControlGetPos($hWin, "", $hCtrl)
$hDC = _WinAPI_GetWindowDC($hWin)
$hGraphic = _GDIPlus_GraphicsCreateFromHDC($hDC)
_GDIPlus_GraphicsClear($hGraphics)
_GDIPlus_GraphicsDrawImage($hGraphic, $hIcon, $aPos[0] + $aPos[2] + 5, $aPos[1] + $aPos[3] - 5)
_GDIPlus_GraphicsDispose($hGraphic)
_WinAPI_ReleaseDC($hWin, $hDC)
;(...)

But now i must delete drawed bitmaps from window. I can't handle graphics objects all time because i'am closing and opening another windows of that application but sometimes i must draw icons then draw them again in another places. But there's problem because i can't delete older icons. _Winapi_RedrawWindow doesn't work.

There's any method to clear that icons? That's what i drawing for example in this window (info icon):
