MattH Posted September 13, 2007 Share Posted September 13, 2007 Just curious. Why is it suggested to use While 1 Sleep(1000) ; Idle around WEnd instead of Sleep(2147483647) for event driven scripts? The memory used by the loop is about three times than that of just sleep. Is there another drawback to using sleep other than the program will terminate in 24 days (at the max value)? Thanks for your help. Link to comment Share on other sites More sharing options...

enaiman Posted September 14, 2007 Share Posted September 14, 2007 Also you might consider the fact that during a Sleep - the script does nothing - it will be practically "frozen" for the amount of time specified - you can't even close it during sleep time. Hope it is a reason good enough Test this and you'll see the point in what I said: #include <GUIConstants.au3> $Form1 = GUICreate("AForm1", 468, 128, 193, 115) $Button1 = GUICtrlCreateButton("AButton1", 104, 40, 273, 41, 0) GUISetState(@SW_SHOW) While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit Case $Button1 Sleep(20000) EndSwitch WEnd SNMP_UDF ... for SNMPv1 and v2c so far, GetBulk and a new example script wannabe "Unbeatable" Tic-Tac-Toe Paper-Scissor-Rock ... try to beat it anyway :) Link to comment Share on other sites More sharing options...

Richard Robertson Posted September 14, 2007 Share Posted September 14, 2007 The script still wouldn't close though, I think. Not if it was sleeping. Link to comment Share on other sites More sharing options...

crash748 Posted September 14, 2007 Share Posted September 14, 2007 But this way, you don't need tight while loop... #include <GUIConstants.au3> Opt("GUIOnEventMode", 1) $Form1 = GUICreate("AForm1", 468, 128, 193, 115) GUISetOnEvent($GUI_EVENT_CLOSE, "CLOSE") GUICtrlCreateButton("AButton1", 104, 40, 273, 41, 0) GUICtrlSetOnEvent(-1, "button1") GUISetState(@SW_SHOW) While 1 Sleep(2147483647) WEnd Func button1() MsgBox(0, "AForm1", "Ouch! You press the button") EndFunc ;==>button1 Func CLOSE() Exit EndFunc ;==>CLOSE Link to comment Share on other sites More sharing options...
martin Posted September 14, 2007 Share Posted September 14, 2007 (edited) The script still wouldn't close though, I think. Not if it was sleeping.You should test it to see if what you think is correct.enaiman might like to know the result.

therks Posted September 15, 2007 Share Posted September 15, 2007 (edited) HotKeySet('{esc}', '_exit') Sleep(0x7fffffff) ; Equivalent to 2147483647 but easier to remember :P Func _exit() MsgBox(0,'Bye','Exit right now!') exit EndFunc*Edit: Whoa, emoticons work inside [autoit] tags?

enaiman Posted September 18, 2007 Share Posted September 18, 2007 (edited) HotKeys will always work when the script is put to sleep And about the Sleep inside the While loop I have to say that I'm a bit confused myself. My idea about the main loop was that the loop is executed over and over (and this is the behaviour of a While loop) when the control is passed back to it - script is idling. So it looks logical to me that once in the While loop the script should execute the instructions between. if the example is: #include <GUIConstants.au3> AutoItSetOption ("TrayIconDebug", 1) Opt("GUIOnEventMode", 1) $Form1 = GUICreate("AForm1", 327, 70, 193, 115) GUISetOnEvent($GUI_EVENT_CLOSE, "AForm1Close") $i=1 $Label1 = GUICtrlCreateLabel($i, 152, 16, 20, 17) GUISetState(@SW_SHOW) While 1 Sleep(1000) $i +=1 GUICtrlSetData($Label1, $i) WEnd Func AForm1Close() Exit EndFunc You can see that indeed the instructions are executed over and over and if you put a very long sleep then the other actions inside the while loop are delayed accordingly = this is the reason for using small Sleep times. Indeed the scipt answers to events if you put a long sleep between but you won't be able to do something inside the while loop. This way (small sleep) I consider to be more "appropriate" for learning and also a good practice (something like eliminating "go to" command). And to tease a little ... change the Sleep inside my loop to 2147483647 and let me know when it will change to next value ... I could wait 25 days for that ... just a little joke Edited September 18, 2007 by enaiman SNMP_UDF ... for SNMPv1 and v2c so far, GetBulk and a new example script wannabe "Unbeatable" Tic-Tac-Toe Paper-Scissor-Rock ... try to beat it anyway :) Link to comment Share on other sites More sharing options...
dpaynebrown Posted September 18, 2007 Share Posted September 18, 2007 While 1 Sleep(2147483647) WEndIf your OnEvent is going to be idle for that long, why even use a loop? Link to comment Share on other sites More sharing options...
