script uses ALOT of cpu ressources

Hello guys.

I made a little script which should run from the autostart and sets up some stuff for me all the time:

#include <Timers.au3>;same as Timers.au3
#include <reducemem.au3>
#include <Constants.au3>
#NoTrayIcon
_ReduceMemory()
sleep(5000)
run("C:\Program Files (x86)\Rainmeter\Rainmeter.exe")
sleep(1000)
run(@ScriptDir & "\wallpaperchanger\wallpaper.exe")
sleep(2000)



while 1


    If _Timer_GetIdleTime() > "600000" Then
        if WinActive("dvd") = 0 And WinActive("firefox") = 0 And WinActive("player") = 0 And ProcessExists("lock.exe") = 0 and WinActive("vmware") = 0 and WinActive("foobar") = 0 and ProcessExists("ET.exe") = 0 Then
            run(@scriptdir & "\lock\lock.exe")          
        EndIf
    EndIf
    
    ;If ProcessExists("ET.exe") Then
    sleep(5000)
    
WEnd


Exit

So it starts from the autostarter folder (useing viat sp2 x64 btw) and waits some seconds so the other programms can load first.. well that was my idea. dont know if the sleep function will really stop the programm from loading.

After some seconds it runs a programm called Rainmeter.. it had some widgeds on the desktop and doesnt use ressource at all. Then it start a little programm to change my wallpaper and after that the wallpaperchanger.exe quits.

So the while starts:

The programm lock.exe is a replacement for screensaver + turning display off. When there is no dvd player,browser,music player,etc active, lock.exe will start. It requires a pw to get acces to windows again (if u enter wrong pw it makes a screen with the webcam in my laptop :) ). And after 10 secs of innactivity lock.exe turns off. I have never checked how many ressources lock.exe uses cause taskmanager is also disabled and the only way to get acces to windows again is to torn off the power of the notebook. How ever here is my problem:

I booted my laptop, did some stuff and went to gym. When i came back i entered my password and lock.exe turned off. I was back on my desktop and reconized my cpu is at 60%.. i checked the ressource momnitor and mainscript.exe (the on in the quote) took 40% of my cpu. Why is that and is there any way to solve this?

btw reducemem.au3 includes this stuff:

Func _ReduceMemory($i_PID = -1)
    
    If $i_PID <> -1 Then
        Local $ai_Handle = DllCall("kernel32.dll", 'int', 'OpenProcess', 'int', 0x1f0fff, 'int', False, 'int', $i_PID)
        Local $ai_Return = DllCall("psapi.dll", 'int', 'EmptyWorkingSet', 'long', $ai_Handle[0])
        DllCall('kernel32.dll', 'int', 'CloseHandle', 'int', $ai_Handle[0])
    Else
        Local $ai_Return = DllCall("psapi.dll", 'int', 'EmptyWorkingSet', 'long', -1)
    EndIf
    
    Return $ai_Return[0]
EndFunc;==> _ReduceMemory()

thanks bb

There are many things wrong with both scripts, but start by adding a Sleep() to the mainloop of both to reduce cpu-usage and get rid of that _ReduceMemory(), it won't help if you call it that often. Use it once when the script start or remove it completely.

hi,

how about inserting a sleep(500) inside the while...wend?

by using 500, the loop will run every half a second. or you can even use sleep(5000) so that the loop executes every 5 seconds instead.

it may drop the cpu resource lower.

hope this helps.

ah great idea thanks.. i will use sleep(5000) in the while loop at the mainscript.exe then

and the redeucemem only when starting the script.

any other ideas?

for the lock.exe i cannot really add a sleep into the mainloop cause then he could start the taskmanager and use it aslong as i have the script sleeping.

@edit:

hmm now every 5 secs my cpu jumps up to 30-40%.. its lower than before but still not a nice solution.. is it the timer_getidletime which takes so much cpu ressources? :)

I cleaned up that Monitor() function a bit. You were checking things that didn't have to be checked.

Func Monitor($io_control = "on")
   Local $WM_SYSCommand = 274
   Local $SC_MonitorPower = 61808
   Local $iState = 2
   Local $HWND = WinGetHandle("Program Manager")
   If $io_control = "on" Then $iState = -1
   DllCall("user32.dll", "int", "SendMessage", "hwnd", $HWND, "int", _
         $WM_SYSCommand, "int", $SC_MonitorPower, "int", $iState)
EndFunc   ;<==> Monitor()
