After a quick search, this showed up:
'?do=embed' frameborder='0' data-embedContent>>

and one of the comments suggested this:

GUIRegisterMsg($WM_QUERYENDSESSION, "Cancel_Shutdown")
GUICreate("PreventShutdownGUI")
GUISetSTate(@SW_HIDE)

; set highest notification level
If Not _SetProcessShutdownParameters(0xFFF) Then ; MSDN says maximum is 0x4FF, but it worked for me
    If Not _SetProcessShutdownParameters(0x4FF) Then ; MSDN says this is reserved for System, but worked for me
        _SetProcessShutdownParameters(0x3FF) ; highest not reserved number, if everything else does not work
    EndIf
EndIf

Global $b_ShutdownInitiated = False

While 1
    If $b_ShutdownInitiated = True then
        $b_ShutdownInitiated = False
        MsgBox(48 + 8192 + 262144, "Installer", "Ending your user session has been disabled to allow the installation to complete." _
        & @CRLF & @CRLF & "You will be able to shutdown/reboot/logoff once the installation process has completed." , 8)
    EndIf
    sleep(10)
WEnd

Func Cancel_Shutdown($hWndGUI, $MsgID, $WParam, $LParam)
    $b_ShutdownInitiated = True
    ; DO NOT ADD A MSGBOX HERE
    ; Windows shows a not responding box after ~5 secs and allows to kill your app.
    Return False
EndFunc


Func _SetProcessShutdownParameters($dwLevel, $dwFlags=0)
    ; <a href='http://msdn.microsoft.com/en-us/library/ms686227%28VS.85%29.aspx' class='bbc_url' title='External link' rel='nofollow external'>http://msdn.microsoft.com/en-us/library/ms686227%28VS.85%29.aspx</a>
    ; Prog@ndy
    Local $aResult = DllCall("Kernel32.dll", "int", "SetProcessShutdownParameters", "dword", $dwLevel, "dword", $dwFlags)
    If @error Then Return SetError(1,0,0)
    Return $aResult[0]
EndFunc

And not 100% sure what everything does, but i can't even test it because this comes up:
 

WARNING: $WM_QUERYENDSESSION: possibly used before declaration.
GUIRegisterMsg($WM_QUERYENDSESSION,
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^

and i don't know what i need to do to fix it.

Any suggestions?

Maffe811,

The WM_ suggests it is a "Windows Message" - and that is indeed where you find it. Just include WindowsConstants.au3. ;)

Can anyone explain me how to get, lets say a message box to pop up when the computer is shuttingdown/logging off ?
Cause i've tried making it work, but nothing makes it work.


GUIRegisterMsg($WM_QUERYENDSESSION, "Cancel_Shutdown")
GUICreate("PreventShutdownGUI")
GUISetSTate(@SW_HIDE)

; set highest notification level
If Not _SetProcessShutdownParameters(0xFFF) Then ; MSDN says maximum is 0x4FF, but it worked for me
    If Not _SetProcessShutdownParameters(0x4FF) Then ; MSDN says this is reserved for System, but worked for me
        _SetProcessShutdownParameters(0x3FF) ; highest not reserved number, if everything else does not work
    EndIf
EndIf

Global $b_ShutdownInitiated = False

While 1
    If $b_ShutdownInitiated = True then
        $b_ShutdownInitiated = False
        MsgBox(48 + 8192 + 262144, "Installer", "Ending your user session has been disabled to allow the installation to complete." _
        & @CRLF & @CRLF & "You will be able to shutdown/reboot/logoff once the installation process has completed." , 8)
    EndIf
    sleep(10)
WEnd

Func Cancel_Shutdown($hWndGUI, $MsgID, $WParam, $LParam)
    $b_ShutdownInitiated = True
    ; DO NOT ADD A MSGBOX HERE
    ; Windows shows a not responding box after ~5 secs and allows to kill your app.
    Return False
EndFunc

Maffe811,

See the example for function _WinAPI_SetProcessShutdownParameters.

This is in the UDF _WinAPIEx.au3, just search the forum for it.
