Turn off monitor and block keyboard & mouse

[temp00]

I'm trying to writing a script which should function like:

Press a hotkey, monitor is turned off and keyboard/mouse input is blocked (except the hotkey);

Press the hotkey again, monitor is turned on and blocking is removed.

For turning off monitor, I use function like:

Func _Monitor_OFF()
Local $Progman_hwnd = WinGetHandle('[CLASS:Progman]')
DllCall('user32.dll', 'int', 'SendMessage', _
'hwnd', $Progman_hwnd, _
'int', $WM_SYSCmd, _
'int', $SC_MonitorPower, _
'int', $Power_Off)
EndFunc

and for keyboard & mouse blocking, I tried _BlockInputEx().

However, the keyboard and mouse can be blocked but the monitor cannot stay turned-off when keyboard or mouse is touched. So, any solution?

Can you please tell us what you need this for? Sounds a bit strange.

It could be used for when you walk away from your PC you want it to go dark and locked. Seems logical to me.

The problem is - Ctrl-Alt-Del can't be blocked, so this idea is not 100% secure.

So why not use Ctrl-Alt-Del or - even faster - Win+L? That's what it was made for, wasn't it?

yep - The problem is the monitor does not go dark when you do this.

So he wants to kill two birds with one stone? Lock the screen and go into power saving mode (darken the screen)?

Temp00, I can see the monitor bit, and locking the screen if you don't want someone on the PC, but can you please explain why you want to completely block all user input?

Mainly for security, when monitor goes blank, any input except for the unlock hotkey should be deemed as invalid~

See the quote regarding "Ctrl-Alt-Del".

Autoit is just another program to windows ... it can block all input ... however Ctrl-Alt-Del will still work.

Only the windows OS can lock out a user.

So ... the question is ... why do you want to turn off the monitor?

A locked user shows the login screen only.

:

As for the monitor, i would use NirCmd, don't know how to do it in autoit,

never tried, Command is: nircmd.exe monitor off

Yes I know that, I believe the fact Ctrl-Alt-Del cannot be blocked is legitimate. I'd like the monitor be turned-off both for energy-saving and for work convenience. I don't like a bright monitor shining in front of me when I read paper work, it's distracting.

In which case - you do not need a hotkey .... this will do ...

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
local $gui = GUICreate("",@DesktopWidth+100,@DesktopHeight+100,Default,Default,$WS_POPUP)
GUISetBkColor(0x000000)
GUISetState()

While 1
    $msg = GUIGetMsg()

    If $msg = $GUI_EVENT_CLOSE Then ExitLoop
WEnd
GUIDelete()

Did you post this code in autoitcode? Because when i copy paste this, it will be a very long string, and the line feeds are not copied.

EDIT: btw theres a missing endif

I do not see a missing EndIf?

EDIT: btw theres a missing endif

There's no missing EndIf in that code, it's a single line If...Then statement which doesn't require, and can't use, an Endif statement.

The copy&paste missed the end bracket in the last line "GUIDelete(" ... which I have now fixed.

The code copies & pastes from the webpage fine for me.

I used the AutoIt code type from the forum editor "code" icon.

sounds phishy... like creating a temporary bug or more of a virus/hi-jack creation. If it doesn't accept user input; how will you turn the pc on to the stage where you can input user password?

Ah...we can call this a work-around, though not pretty

What do you mean by "phishy"? I think you should read my first post again~ A hotkey is excluded from blocking for toggle the monitor/keyboard&mouse

After your thread yesterday, where you refused to give the title of the window you were trying to manipulate, should you really be casting doubt on anyone else's post?
