Hi! I am searching for a way to display a transparent image (or Icon) over an Button. And the image should always stay on top. Here is what i have so far: At script start the picture is over the button..but if you move the mouse over the button it overlaps the image. And if i add $GUI_ONTOP to the picture, the transparency is gone Maybe someone has an idea.. Thanks in advance! #include <GUIConstantsEx.au3> #include <WindowsConstants.au3> #include <GUIConstantsEx.au3> #include <StaticConstants.au3> #include <WinAPIIcons.au3> #include <WinAPIShellEx.au3> GUICreate("GUI", 300, 300) $hbutton = GUICtrlCreateButton("This is a button", 20, 40, 150, 30,$WS_CLIPSIBLINGS) $hpic = GUICtrlCreatePic("", 10, 10, 128, 128) _SetIconAlpha($hpic,"shell32.dll", 12,128,128) GUICtrlSetState(-1, $GUI_DISABLE) ;~ GUICtrlSetState(-1,$GUI_ONTOP) ;If you uncomment this..the picture is on top...but the transparency is gone :( GUISetState() While 1 $Msg = GUIGetMsg() If $Msg = $GUI_EVENT_CLOSE Then ExitLoop WEnd Func _SetIconAlpha($hWnd, $sIcon, $iIndex, $iWidth, $iHeight) If Not IsHWnd($hWnd) Then $hWnd = GUICtrlGetHandle($hWnd) If $hWnd = 0 Then Return SetError(1, 0, 0) EndIf EndIf If $iIndex <> 0 Then $iIndex = $iIndex - 1 Local $hIcon = _WinAPI_ShellExtractIcon($sIcon, $iIndex, $iWidth, $iHeight) If $hIcon = 0 Then Return SetError(1, 0, 0) EndIf Local $hBitmap, $hObj, $hDC, $hMem, $hSv $hDC = _WinAPI_GetDC($hWnd) $hMem = _WinAPI_CreateCompatibleDC($hDC) $hBitmap = _WinAPI_CreateCompatibleBitmap($hDC, $iWidth, $iHeight) $hSv = _WinAPI_SelectObject($hMem, $hBitmap) _WinAPI_DrawIconEx($hMem, 0, 0, $hIcon, $iWidth, $iHeight, 0, 0, 2) _WinAPI_ReleaseDC($hWnd, $hDC) _WinAPI_SelectObject($hMem, $hSv) _WinAPI_DeleteDC($hMem) _WinAPI_DestroyIcon($hIcon) _WinAPI_DeleteObject(_SendMessage($hWnd, 0x0172, 0, 0)) _SendMessage($hWnd, 0x0172, 0, $hBitmap) $hObj = _SendMessage($hWnd, 0x0173) If $hObj <> $hBitmap Then _WinAPI_DeleteObject($hBitmap) EndIf Return 1 EndFunc ;==>_SetIconAlpha
