Simple script with 30% CPU usage !

Hi all

this is a part from my script

#include <Misc.au3>
$dll = DllOpen("user32.dll")

    While 1
    If _IsPressed("31", $dll) Then one()
    If _IsPressed("32", $dll) Then two()
WEnd

Func one()
    MsgBox(0, "", "1")
    While _IsPressed("31") or _IsPressed("61")
        Sleep(1)
    WEnd
EndFunc

Func two()
    MsgBox(0,"", "2")
    While _IsPressed("32") or _IsPressed("62")
        Sleep(1)
    WEnd
EndFunc

it is working fine but it takes 30 % of the CPU usage and it is a small simple script

when i put sleep(100) in the while loop the CPU is 1%

i think that this is a good solution but not for my case cuz the rest of my script really depends on time and 100 msec will matter

can i reduce the CPU usage without using sleep ?

There's no sleep in your While loop unless you're pressing a key, actually there's no sleeps in any of your while loops unless a key is pressed.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

in HelpFile GUIGetMsg() from latest BETA

 

This function automatically idles the CPU when required so that it can be safely used in tight loops without hogging all the CPU.

 

Try to use this function GUIGetMsg().

Or don't, and use a sleep like you should, using GUIGetMsg on a script with no GUI is kind of pointless.
