Why does this script use about 5% of the cpu?

If you want to run the whole thing put the second file in the same dir

My CPU usage bounces between 0% and 4% before running the script, and between 0% and 5% while running the script, but hits 5% only about 1/4 of the time. That's doesn't seem so bad.

System Specs:

XP SP1

P4, 3.06GHz

512MB RAM

Blah

Thanks for testing it.

it probably wont get better than that, i worked for a few hours trying to make mine take less CPU but i never could get it less than 0-5%

Alright, thanks

use a true "Deep Sleep"

include the following:

Func _DeepSleep ($timetowait)
; Call system KERNEL32's Sleep, $timetowait SEC
    local $timetowait_ms                    ; for conversion
    $timetowait_ms=$timetowait*1000; adjust to MS
    DllCall("KERNEL32.DLL","none","Sleep","int",$timetowait_ms)
EndFunc

just change your Sleep(10) statement with

if WinActive("iClock") then
        Sleep(10); to ensure "normal" GUI operations are not too sloowwww 
   Else
        _DeepSleep(10); wait before testing next "timer" here 10s (could be set hiher see comment below)
   EndIf

CPU using origial coding: 5 to 6%

CPU using _DeepSleep: almost "nothing" (except during GUI operations)

obviously depend on the time resolution set

timer parameters resolution should be set higher than "timetowait" not to miss them

Only Drawback: "WINDOWS+C" and "Tray Icon CLICK" should wait at least "1 timetowait" long (but y're nat changing alarm every seconde )

No adverse noticeable effect on other programs running or total CPU load on a W98 system

EDIT> CAUTION if you choose a high value for "timetowait" (say 10th of mn or hours) your script will not receive any message, nor could be interrupted using tray icon all that long!!! (to be stopped process has to be "Killed") so be careful <EDIT
