How do you first clear an image without resizing the control (as a function)? I'm not sure if this is a bug but if you compare clearing as a function vs as a global? it works differently? I need to clear the image first as sometimes no image file is found #include <ButtonConstants.au3> #include <EditConstants.au3> #include <GUIConstantsEx.au3> #include <ColorConstants.au3> #include <StaticConstants.au3> #include <WindowsConstants.au3> $hMain = GUICreate("Test", -1, 300, -1, -1, BitOr($WS_SIZEBOX, $WS_SYSMENU, $WS_MAXIMIZEBOX, $WS_MINIMIZEBOX), $WS_EX_ACCEPTFILES) $btn = GUICtrlCreateButton("Change", 120, 80, 75, 20, $BS_DEFPUSHBUTTON) $picUser = GUICtrlCreatePic("", 270, 10, 100, 80) $sImage = "C:\Windows\Web\Screen\img100.jpg" GUICtrlSetImage($picUser,""); - can be left alone without resizing control $sImage = "C:\Windows\Web\Screen\img104.jpg" GUICtrlSetImage($picUser, $sImage) GUISetState(@SW_SHOW) While True $nMsg = GUIGetMsg() Select Case $nMsg = $GUI_EVENT_CLOSE Exit Case $nMsg = $btn ButtonPressed("C:\Windows\Web\Screen\img102.jpg") EndSelect WEnd Func ButtonPressed($imagelocation) ;GUICtrlSetImage($picUser,""); - don't comment out - it will clear picture but resize control GUICtrlSetImage($picUser, $imagelocation) EndFunc
