z-order of desktop's icons & child window

[Michel Claveau]

Hi, all!

I know insert a GUI (window) inside Desktop:

#include<guiconstants.au3>
#include<WindowsConstants.au3>
#Include <WinAPI.au3>
#Include <Constants.au3>

$hbureau=WinGetHandle("[CLASS:Progman]")
$hGui1 = GUICreate("GUI Embedder",420,300,-1,-1,$WS_POPUP)
$btclose=GUICtrlCreateButton("Fermer / Close",100,125,220,50)
GUISetState(@SW_SHOW)
$origParent1 = DllCall("user32.dll", "int", "SetParent", "hwnd", $hGui1, "hwnd",$hbureau)
WinMove($hGui1, "", 80,50)
While 1
    $Msg = GUIGetMsg()    
    If ($Msg=$GUI_EVENT_CLOSE) Or ($Msg=$btclose) Then
        DllCall("user32.dll", "int", "SetParent", "hwnd", $hGui1, "hwnd", $origParent1[0])
        ExitLoop
    EndIf
    sleep(12)
WEnd
GUIDelete($hGui1)
Exit

But the GUI is over icons. Now, I would want it below icons (like background-screen/wallpaper).

I tried

_WinAPI_SetWindowPos($hGui1, $HWND_BOTTOM, 80, 50, 420, 300, $SWP_NOACTIVATE)

to change z-order, but that works with a window inside desktop.

An idea?

I think that this is non-trivial task.

Thank you.

But the word "trivial" is not synonym of "impossible".

If it is possible, we can re-create (replace) the old (XP) ActiveDesktop, which does not exist any more in Vista & Win-7, with an Autoit's script.

I think you are unlikely to be able to do that. I suspect the desktop is continually updated to ensure that the z-order is kept as required.

Maybe instead you could create your window, and copy all the icons and shortcuts on the desktop into your window.
