Disable GUI in Taskbar and ALT+TAB dialog

[Jotos]

Hey!
I have created a GUI with

WinSetOnTop($Form1, "", 1)

So far everything works great, but now I would like the GUI to be displayed on the desktop, but not in the taskbar and also not in the ALT+TAB - dialog.

How can I realize this?

Have you tried this?

#include <WinAPI.au3>
#include <WindowsConstants.au3>

Local $hWnd = WinGetHandle($Form1)
Local $iStyle = BitOr(_WinAPI_GetWindowLong($hWnd, $GWL_EXSTYLE), $WS_EX_TOOLWINDOW)
_WinAPI_SetWindowLong($hWnd, $GWL_EXSTYLE, $iStyle)

WinSetOnTop($Form1, "", 1)

By setting the form's parent to AutoIt's hidden window, it will not be shown in the taskbar.

#include <GUIConstants.au3>

Global $ghParentForm = WinGetHandle(AutoItWinGetTitle()) ;Get handle to AutoIt's hidden window
Global $frmMain      = GUICreate("Example Form (Pres ESC to Close)", 500, 300, -1, -1, -1, -1, $ghParentForm)

GUISetState(@SW_SHOW, $frmMain)

WinSetOnTop($frmMain, "", 1)

Do
Until GUIGetMsg() = $GUI_EVENT_CLOSE

I also tried your suggestion. 
The GUI was no longer present in the taskbar, but it was still visible in the ALT+TAB dialog.
