My script uses so much CPU Please help me!!

[Blastblood]

My script is using so much CPU

#include <Timers.au3>
$starttime = _Timer_Init();starts timer

while(1)
if _Timer_Diff($starttime)>3000 Then 
    MsgBox(0,"asdas","high time!"); show a message in every 5 secs "i was to use it for calling a func but it uses so much cpu"
    $starttime = _Timer_Init() ; to reset the timer
    EndIf
WEnd

i have a func which include while wend codes in my main script but i dont want the func to fulfill lines every time. But in every 3 sec. I write a script like this, it works but uses so much CPU (about 50%). I can't use sleep instead of timer method because i have a GUI window and edit fields during sleep they become inactive etc etc

Please suggest me some new methods to run a fucn every xx time or a method to reduce the usage of CPU.

Sorry for the bad english by the way

Note: is there any code like "local sleep()" which only sleeps the func not the whole script

Read up on the GUIGetMsg function under the Message Loop Mode in the help file.

Ok i solve the problem with this

$timer = TimerInit ()
While 1
    $nMsg = GUIGetMsg ();i dont know what are these codes for but it works =D
    Switch $nMsg
        Case - 3
            Exit
    EndSwitch
    If TimerDiff($timer) >= 5000 Then;5 Seconds
        $timer = TimerInit()
        MsgBox(0,"asd","asdasd")
    EndIf
WEnd

GUI Reference - MessageLoop Mode

$nMsg = GUIGetMsg ();i dont know what are these codes for but it works =D

Basic MessageLoop Format

The general layout of MessageLoop code is:

While 1
 $msg = GUIGetMsg()
 ...
 ... 
WEnd

Usually a tight loop like the one shown would send the CPU to 100% - fortunately the GUIGetMsg function automatically idles the CPU when there are no events waiting. Do not put a manual sleep in the loop for fear of stressing the CPU - this will only cause the GUI to become unresponsive.

Thanks for your advise

Just for the record: You use GUIGetMsg() when you want to "read" the messages from your GUI,.

In this case just simply put a Sleep(10) in the While...Wend loop.
