timer functions

[KAX 0]

Hi AutoIt fans!

I would like to use a timer service to get awaked when timer has expired.

But it should work without polling. Means using sleep and waiting in loops.

Has someone got a good idea ?

$Timer_Expiration_Time = 10000 ;10 seconds.
$Timer = TimerInit()

Do
    Sleep(500)
Until TimerDiff($Timer) >= $Timer_Expiration_Time

MsgBox(0, "Time Expired", "It has been " & $Timer_Expiration_Time / 1000 & " seconds.")

This is not the 'optimal' solution I'm loolking for. Because it doesn't allow you easily to add more timers.

My favorite structure looks like:

...
$timer1 = CreateTimer()
StartTimer($timer1, 1000)  ;starts timer1, time in ms
while $performMainLoop ; main loop

    $msg = GUIGetMsg(1)
    Select
        Case $msg[0] = $GUI_EVENT_CLOSE
            Exit

                Case $msg[0] = $TIMEREXPIRED
                        ; check which timer
                        ; perform appr. action
                         StartTimer($timer1, 500); restart it
                ....
    EndSelect
Wend

$Timer1_Expiration_Time = 10000 ;10 seconds.
$Timer2_Expiration_Time = 8000 ;8 seconds.
$Timer3_Expiration_Time = 30000 ;30 seconds.

$Timer1 = TimerInit()
$Timer2 = TimerInit()
$Timer3 = TimerInit()

While 1
    Select
        Case TimerDiff($Timer1) >= $Timer1_Expiration_Time
            ;Do something...
            
            $Timer1_Expiration_Time = 5000
            $Timer1 = TimerInit()
            
        Case TimerDiff($Timer2) >= $Timer2_Expiration_Time
            ;Do something else..
        
        Case TimerDiff($Timer3) >= $Timer3_Expiration_Time
            ;Do something else..
            
    EndSelect
WEnd

Something like this? Maybe I am not understanding correctly.

Thanks Zib,

this solution consumes the CPU-power inside the loop, because it polls the used timers at every loop step. I prefer a solution ala WM_TIMER. Which winds up the timers and then only waits for messages. (Hope the waiting for messages does not steal the CPU from all the concurrent running processes!)

unsolved questions to timer functions

The timer function:

DLLCall("user32.dll","int_ptr","SetTimer","hwnd",$gui,"int_ptr",$nID,"int",2000,"ptr",0)

generate repeated timeouts. So good so far. But it seems, that the timers haven't designed to be operated in start-stop mode. (To restart a timer only when a certain event has occured). An other point is to change the timeout.

Can someone help?
