(1st post)

I'm trying to write a routine that functions like a screen saver but instead of popping up a screen saver, displays a msgbox(). Testing for mouse movement is easy enough, but testing for keyboard activity has proven to be much more of a challenge.

This snippet from my script seems to function fine except, even with sleep set as low as 1, it pegs CPU utilization. I have to bump sleep time way up before I see utilizaton drop, but then the loop misses keystrokes. I'm hoping to launch this to about 6000 workstations. Having the CPU at 99% would likely burn up a few. Does anyone have any ideas how I can make this work?

Thanks for looking.

.........
While 1
   For $y = 1 To $s_keys[0]
   If _IsPressed ($s_keys[$y], $dll) Then
      $LastKeyTime = TimerInit()
   Else
      If TimerDiff($LastKeyTime) > $TimeOut Then
         ExitLoop(2)
      EndIf
   EndIf
   Sleep($CPURelief)
   Next
WEnd
........

Hm I think you could work with HotKeySet(...), the keys don't work then, if you want to write something else, but if i understood your problem, you only want to stop your screensaver, when a key is pressed? Then it wouldn't matter if the keyboard works for other things.

You just have to do HotKeySet for every Key then with the "stopscreensaver" function.

I don't know if there are other ways to realize that with Autoit.

With C++ you can surely get a keyboardaction as a message (correct me, if i'm wrong^^) and autoit is C++ based, but i don't know, if you can get that message with autoit.

Dumb question, but why would one need something like this?

Is it really dumb? I think it's a real problem to check, if there was a keyboard action (without isPressed and HotKeySet), so why don't you just post a solution, if you know one, instead of call that dumb? Maybe you don't need that, for such a thing as Tim wanted it, but it's surely useful.

He said it was for a screen saver right?

Replace the msgboxes with whatever you need to turn off screen saver

EDIT: whoops I accidentally put 'thens' on my case statements :)

Or something like this:

#include <GUIConstants.au3>

Opt("GUIOnEventMode", 1)

$FakeWindow = GUICreate("")
$MainWindow = GUICreate("Screensaver", @DesktopWidth, @DesktopHeight, 0, 0, $WS_POPUP, $WS_EX_TOPMOST, $FakeWindow)

GUISetOnEvent(-11, "_EventHandler")

WinSetTrans($MainWindow, "", 1)

GUIRegisterMsg(0x0100, "KEYPRESS")
GUISetState()

While 1
    Sleep(1000)
WEnd

Func KEYPRESS()
    Exit
EndFunc

Func _EventHandler()
    Switch @GUI_CtrlId
        Case -11, -3
            Exit
    EndSwitch
EndFunc

Func OnAutoItExit()
    MsgBox(0, "Exit", "A key has been pressed or the mouse has been moved. Goodbye!")
EndFunc

?

As Tim said, that would need too much CPU, keyloggers surely better (how could i forget it?)^^

I'm not hoping to interact with the screen saver at all. My routine reads a text file on my company network into an array and displays it in a message box. I'd like it to display once every 4 hours ( twice per shift) but only display if the machine has been inactive for 10 minutes or so. I don't care if the screen saver comes on in the meantime since the user will see the pop-up message as soon as they touch the workstation.

The idea is that I can have someone in Marketing edit the message on some kind of routine basis. Everyone will see the message pop up once in a while and I don't have to be involve in the content of the message.

Everything functions fine the way I have it except for the CPU problem.

Thanks for your help.

Larry, that should do perfectly. I'm not sure how it's doing what it's doing, but the result are exactly what I'm looking for. Zero cpu utilization and accurate key or mouse movement sensing. I'll incorporate it into my script tomorrow and let you know how it works.

Thanks!

#include <misc.au3>
While 1
    sleep(10)
    For $i = 0 to 255
        if (_IsPressed(Hex($i))) Then
            MsgBox(0, "", "You pressed the: " & Chr($i) & " Key!")
        EndIf
    Next
WEnd

here is something to check ever key... Simpler than a case statement for every character...

here is a knockoff of something that gafrost did. It tooltips the amount of idle seconds that have gone by...

HotKeySet("{Esc}", "_Terminate")

Dim $last_active = 0
Dim $timer = TimerInit()

While (1)
    $not_idle = _CheckIdle($last_active)
    If $not_idle <> 0 Then $timer = TimerInit()
    ToolTip(Int(TimerDiff($timer)/1000))
    Sleep(200)
WEnd

Func _CheckIdle(ByRef $last_active, $start = 0)
    $struct = DllStructCreate("uint;dword");
    DllStructSetData($struct, 1, DllStructGetSize($struct));
    If $start Then
        DllCall("user32.dll", "int", "GetLastInputInfo", "ptr", DllStructGetPtr($struct))
        $last_active = DllStructGetData($struct, 2)
        Return $last_active
    Else
        DllCall("user32.dll", "int", "GetLastInputInfo", "ptr", DllStructGetPtr($struct))
        If $last_active <> DllStructGetData($struct, 2) Then
            Local $save = $last_active
            $last_active = DllStructGetData($struct, 2)
            Return $last_active - $save
        EndIf
    EndIf
EndFunc ;==>_CheckIdle

Func _Terminate()
    Exit

Or perhaps a simple timer..

$timer = TimerInit()
While 1
    Sleep(5)
    ToolTip(TimerDiff($timer))
    If TimerDiff($timer) > 5000 Then
        Msgbox(0,"","5 seconds have gone by, let's restart")
        $timer = 0
        $timer = TimerInit()
    EndIf
WEnd

I don't like using sleep if you want the script to stall for 10+ seconds. Reason: you check nothing/do nothing during a sleep, whereas a timer allows for you to control everything, even within the sleep period.

I too will be using this information, thank you very much gafrost you have clearly earned the title AutoIt MVP!!!

This should be put in the examples section to make it easier to find!
