Intercept Shutdown

[dantay9]

I was wondering if there was a way to intercept the shutdown function called when you click the red shutdown button. I saw TheSaint's Shutdown Options program, but I didn't see where the shutdown message was intercepted. How can I intercept the shutdown message with a script and then run the script?

I don't want to abort the shutdown, I just want to intercept the message the the shutdown sequence has begun.

Holy crap, did you not take note of what's happening in the script in the thread that I posted? Did you not bother to read it?

Because if you did read it, which I doubt, you would have noticed one thing.

THE MESSAGE WAS INTERCEPTED!

That is what you were asking correct?

So let me save you the trouble of looking for the script in that thread and post it here. All thanks to The Kandie Man...

Opt("TrayIconHide", 1)

$WM_QUERYENDSESSION = 0x0011
GUIRegisterMsg($WM_QUERYENDSESSION, "Cancel_Shutdown")
GUICreate("PreventShutdownGUI")
GUISetSTate(@SW_HIDE)
Global $b_ShutdownInitiated = False


While 1
    If $b_ShutdownInitiated = True then
        MsgBox (0, "", "OMG!")
       ;Do stuff here
       ;do some more stuff here
       ;DoTheShutDownStuff();maybe do some more stuff here wink.gif
       ;Shutdown();Maybe you want to shutdown the computer when done
        Exit;otherwise, you just exit this script
    EndIf
    sleep(10)
WEnd

Func Cancel_Shutdown($hWndGUI, $MsgID, $WParam, $LParam)
;~   run(@ScriptDir & "\killpgm.exe")
    $b_ShutdownInitiated = True
    Return False
EndFunc

SO HOW ABOUT YOU TAKE A CLOSER LOOK AT IT!

I'm sorry but I don't understand the script. Mainly these two lines:

$WM_QUERYENDSESSION = 0x0011

GUIRegisterMsg($WM_QUERYENDSESSION, "Cancel_Shutdown")

Can you explain what is happening here? I don't understand this at all.

[BrettF]

Google it.

Actually here. I will.

Oh! I get what the GUIRegisterMsg does now, but why is $WM_QUERYENDSESSION set to equal 0x0011? Thanks!

[dantay9]

I see now. That is just like declaring a variable. Thank you for your patience and help.

This code works great on Windows XP but not on Vista. Any ideas how to get something like this to work on Vista machines?

See the giberish? Try to use just the [code ][/code ] tags for that exact reason
