I am trying to write a script which will let programs run, but with blockinput and the screen black. I had a code which went something along the lines of: (I deleted original)

Code:

^a::
BlockInput, On
SendMessage 0x112, 0xF170, 1,,Program Manager
^!{delete}::Shutdown, 4   ; ?
BlockInput, Off
Exit


so basically, I wanted the computer to kill all programs and shut down right away. However, the control-alt-delete hotkey didn't work, so i tried just control, with this code:

Code:

^a::
BlockInput, On
SendMessage 0x112, 0xF170, 1,,Program Manager
^::Shutdown, 4   ; ?
BlockInput, Off
Exit


however, this did not work either. this leads me to believe that i wrote the command wrong, so how would you write that kind of code?

currently, i am using this code:

Code:

^a::
BlockInput, On
Gui, +AlwaysOnTop +LastFound +Owner -Caption
Gui, Color, Black
Gui, Show, x0 y0 Maximize
sleep, 18000000
BlockInput, Off
Exit


Which works, because the screen stays black until you somehow kill the script. How can I make a script which will basically turn the screen black and stop anyone from being able to recover the data in question without restarting the computer and finding the folder in which it is?


total: 3 questions:

Can Ctrl-Alt-Del be used as a hotkey?

How can I write a command that will terminate a script when a button is pressed at a point in the script?

Can someone help me make my script unterminateable by blocking access to task manager?

1. Nope.
2.
Code:
esc::
exitapp
return

(Escape exits script)
3. Search the forum.

Yes!

Code:
^!Del::MsgBox


But you cannot supress its native function - That is, the Task Manager

does Ctrl-Alt-Del pause the script? if it doesn't, you could have it be something like:

Code:

^!Del::
Sleep, 5
Send, {tab}
Sleep, 5
Send, {tab}
Sleep, 5
Send, {tab}
Sleep, 5
Send, {tab}
Sleep, 5
Send, {tab}
Sleep, 5
Send, {enter}
return


this would tab to the "cancel" button and press it.

the sleep 5 commands in the script are for compatibility with slower computers, or lag, because i have had my computer lag and not register some of the tabs.

EDIT: didn't work for me, anyone else?

what didnt work? or what worked exactly? whole script?
alt+F4 closes active window including task manager, which preferbaly is a better solution to closing the window.
or just use
Code:

WinWaitActive, TaskManager ;; waits for task manager win to be active
Winclose ;; then closes

thank you. missed that.

Code:
WinWait Windows Task Manager
WinClose


works, no need for WinWaitActive command, which might be circumvented by starting task manager is the background and pressing "end process" button on the script, since it would end the script first.
