GUISetCursor trouble

[dejhost]

Hi everybody,

I have troubles using the function "GUISetCursor" properly.

My script generates a small GUI and opens an image in IrfanView. If the user hits the button "$p_coord" on the GUI, the GUI shall be hidden, IrfanView shall become active and the mousepointer shall turn into a cross (as long hovering over IrfanView). Once clicked into IrfanView, the cursor shall turn into a nordinary mousepointer again.

Unfortunately, the cross doesn't appear until the user clicks into IrfanView manually. Then the mousepointer changes for the duration of the click into the cross. Can anybody tell why this is happening?

Here is the relevant code:

GUISetState(@SW_SHOW, $hGUI)                                        ;the autoit gui is hidden

; Loop until the user exits:
    While 1
        Switch GUIGetMsg()
         Case $GUI_EVENT_CLOSE
                ExitLoop
         Case $p_coord
                WinSetState("Bicon Coordinator","",@SW_HIDE)        ;the autoit gui is hidden
                $Handle = WinActivate ( "IrfanView")                ; IrfanView is activated
                GUISetCursor (15,1,$Handle)                         ;Cursor should be turned into a cross - this is what fails :-(
                While 1                                         
                    If _IsPressed ("01", $hDLL) Then                ;Once a mousclick by the user is performed... 
                        GUISetCursor (2) 
                    EndIf
        EndSwitch
    WEnd

@dejhost,

are you sure GetSetCursor() is supposed to work on external windows? as i understand, it works on your script GUI.

if it does work on external windows, check that the WinActivate returns a valid handle.

I believe that GUI* functions work only on the AutoIt GUIs created in the same script that they're used in.

WinActivate returns a proper handle.  So obviously you're right:  GUISetCursor() only works on the autoit GUI. I see two options to solve this:

1. Replace IrfanView with GUICtrlCreatePic()
2. Change the windows registry entry: HKEY_CURRENT_USER\Control Panel\Cursors  and C:\Windows\Cursors respectively.

Thanks for your input. It is very much appreciated.
