Delay shutdown - Win7

[supraspecies]

Good day. I'm scripting Photoshop install. After the install is done, Photoshop may call for a system reboot. Problem is - there is still a bunch of stuff I'd like to do before that. So I need a UDF that would delay restart until the script finishes, or any advice on how to do it will work just as well. Tried OnAutoItExitRegister, but it delays reboot for XP only.

I've searched the forum, but failed to find a really reliable UDF that'd work on Win7. I could have easily overlooked, I'm relatively new, thats why I'm asking for help. Thanks in advance.

If you catch it in time you could use the dos command -->> shutdown -a (thought this was it???)

EDIT - not -s but -a, still looking, thought -a was abort

Yeah, I read about that. And how do I catch the time?

[nitekram]

You said photoshop is being installed - is there any window that pops up after it is complete and says that it is restarting - if you catch that window, then you can run that command?

[supraspecies]

Hm... No, no popup. Upon clicking "Finish", it closes the window and goes into restart. Could probably attach command by "WinWaitClose", supposedly by the time window closes, the command is already sent, I just can't be sure about that. Would thoroughly test it, but the damn thing installs/uninstalls for 20 minutes for me. So there is no real way to delay the shutdown until the script is done? At all?

[nitekram]

If, right after you press finish, you use the command shutdown -a -->> it should work?

My thought was that you were using AutoIt to install the application, right after you press the finish button, try the command and see what happens?

A few methods here for detecting the shutdown, the easiest is that application windows receive a WM_QUERYENDSESSION message, so if you have a GUI then just use GUIRegisterMsg.

To prevent the shutdown automatically occuring, you can just return false from WM_QUERYENDSESSION. That causes the screen to dim and gives the user the option to terminate the process (like when you try and shutdown and there are non-responsive programs).

Better would be to use the ShutdownBlockReasonCreate function.

@ nitekram

Yes, I was thinking the same thing, but I don't know how reliable that would be: after the window closes, both - Photoshop and my script would pass shutdown/abort shutdown command. What if my script passes "abort" BEFORE Photoshop passes "shutdown"? Theoretically it does that upon clicking "Finish" button, but practically... who knows. That's the general reason why I was looking for something more reliable.

@ Mat

Thanks! No, no GUI, but you pointed me in the right direction.

Sorry for a new post, couple of days have passed. Anyone has an idea why doesn't this work?

OnAutoItExitRegister("shut")

***My Script***

Func shut()

Run(@ComSpec & " /c shutdown.exe -a")

EndFunc

When Windows was shutting down, the script was running, so when Windows called it to exit, it was supposed to run this function. And yet no go. Any ideas why?

EDIT: Tried to abort the shutdown in progress with a BAT, got "The action has failed to initialize properly". Not a very reliable command, is it...
