Why while 1 to Wend CPU 100%

[autoitxp]

Hi

i want to to know y between While1 to Wend take 100% cpu usage sleep time will reduce cpu usage

but any one know any better solution for continue loop

If your loop is waiting for you to press a button or select something you could use GUIGetMsg

put a Sleep(100) in your While 1 Loop. That should not spike the CPU usage.

or

sleep(1)

it's enough.

sleep(1)

Yep! Depending on your hadware, this is a rather true statement.

AutoIt is trying it's best to do tasks the fastest it can, and that also counts

for loops. Also, if there's no point in the loop where the script gets any time

to "rest", the CPU-usage will go to 100%, which is understandable...

As the other people said, you will avoid this problem if you add a tiny Sleep

to your script. I personally use Sleep(1), and in some script I even use the

GUIGetMsg()..also for non-GUI scripts.

I did a time test on Sleep(1) to Sleep(9) and they were all the same as Sleep(10)

Hi

Thanks okay helge how to use GUIGETMSG() for non-GUI script

for example in this case here sleep(100) works but i really want to avoid sleep() so tell how GUIGETMSG() works here in non-GUI script

While 1
   If ProcessExists('NOTEPAD.EXE') Then ProcessClose('NOTEPAD.EXE')
WEnd

I did a time test on Sleep(1) to Sleep(9) and they were all the same as Sleep(10)

yup i agree i also test 1 to 9 same as 10 no differnce i feel

1000 = 1 second, what can sleep(10) possibly hurt? you'll never know the difference.

Here's my useles contribution

For $i = 1 To 100
    $Time = TimerInit()
    Sleep($i)
    ConsoleWrite('Time for Sleep(' & $i & ') = ' & TimerDiff($Time) / 1000 & @LF)
Next

...Thanks okay helge how to use GUIGETMSG() for non-GUI script

for example in this case here sleep(100) works but i really want to avoid sleep() so tell how GUIGETMSG() works here in non-GUI script...

Hmm...just put it in your script, where you would normally put the Sleep()

Note that I rarely use this method; it's basically only when speed really matter,

and when I also want to avoid using to much CPU-power, thanks to the auto-idle.

[pecloe]

i guess you don't need a gui to use guigetmsg() learn something everyday!
