Help: GUI that stays on the bottom, i.e. on the desktop

[B4l4]

Hi, I'm trying to create a program that sits on the desktop, i.e. I want the program to be always be at the bottom.

I've tried using 

_WinAPI_SetWindowPos

with $HWND_BOTTOM, but it doesn't work. Can anyone help? Thanks.

Hi Francesco, here's the code, based on an example online:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <WinAPISysWin.au3>


BackgroundImage()

Func BackgroundImage()
    GUICreate("My background image", 1000, 300, -1, -1, $WS_SIZEBOX + $WS_SYSMENU) ; will create a dialog box that when displayed is centered
    Sleep(1000)
    $hWnd = WinGetHandle("[ACTIVE]")
    WinActivate($hWnd)

    GUISetBkColor(0xE0FFFF)
    Local $idPic = GUICtrlCreatePic("C:\Users\b4l4\Documents\misc\test.jpg", -1, -1, 1000, 1000)

    GUISetState(@SW_SHOW)


   _WinAPI_SetWindowPos($hWnd, $HWND_TOP, 0, 0, 0, 0, BitOR($SWP_FRAMECHANGED, $SWP_NOMOVE, $SWP_NOSIZE))

    ; Loop until the user exits.
    While 1
       _WinAPI_SetWindowPos($hWnd, $HWND_TOP, 0, 0, 0, 0, BitOR($SWP_FRAMECHANGED, $SWP_NOMOVE, $SWP_NOSIZE))
       ;WinActivate("Program Manager")
       Sleep(100)
        Switch GUIGetMsg()
            Case $GUI_EVENT_CLOSE
                ExitLoop
        EndSwitch
    WEnd

    GUIDelete()
 EndFunc   ;==>Example

Thanks.

Slight modification, seems to work

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <WinAPISysWin.au3>


BackgroundImage()

Func BackgroundImage()
    $hWnd = GUICreate("My background image", 1000, 300, -1, -1, $WS_SIZEBOX + $WS_SYSMENU) ; will create a dialog box that when displayed is centered
    Sleep(1000)
;~     $hWnd = WinGetHandle("[ACTIVE]")
;~     WinActivate($hWnd)

    GUISetBkColor(0xE0FFFF)
    Local $idPic = GUICtrlCreatePic("C:\Users\b4l4\Documents\misc\test.jpg", -1, -1, 1000, 1000)

    GUISetState(@SW_SHOW)


   _WinAPI_SetWindowPos($hWnd, $HWND_BOTTOM, 0, 0, 0, 0, BitOR($SWP_FRAMECHANGED, $SWP_NOMOVE, $SWP_NOSIZE))
   If @error Then ConsoleWrite("Error: " & @error & @CRLF)

    ; Loop until the user exits.
    While 1
       _WinAPI_SetWindowPos($hWnd, $HWND_BOTTOM, 0, 0, 0, 0, BitOR($SWP_FRAMECHANGED, $SWP_NOMOVE, $SWP_NOSIZE))
       If @error Then ConsoleWrite("Error: " & @error & @CRLF)
       ;WinActivate("Program Manager")
        Switch GUIGetMsg()
            Case $GUI_EVENT_CLOSE
                ExitLoop
        EndSwitch
    WEnd

    GUIDelete()
 EndFunc   ;==>Example

Oops, yes, my mistake then? Need to read the manual more closely. 

Can you tell me why the app flickers though? Any way to remove it? Thanks again!

@B4l4
Try to comment the _WinAPI_SetWindowPos in the While 1 loop

[careca]

Compare the position with the position you want, if = then skip the setwindowpos func, else, reposition the window.

This is how you avoid the flickering which is the constant and repeated window position set.
