How to Timeout a Loop

5 posts in this topic

trying to run a progress metere through a loop until a process ends. Got that part working fine.

Issue is now that I need to time that out....

Tried the following....but it doesn't exit if Process ends

Excluded Variable sets.

Any ideas?

Thanks..

do

If $dif > 2100000 then

MsgBox (48, "ATTENTION",$dif)

MsgBox (48, "ATTENTION", "Process has timed out.")

ProcessClose("notepad.exe")

exitloop

endif

; Progress Meter

ProgressOn("PSTs Processing-Please be patient.", "DO NOT INTERRUPT THIS PROCESS.", "0")

For $i = 10 to 100 step 10

sleep(1000)

ProgressSet( $i, $i & "")

Next

ProgressSet(100 , "", "")

sleep(500)

ProgressOff()

Until $procpstrunning = 0

Tried the following....but it doesn't exit if Process ends

I do not see any code here that would help in exiting:

do 
   If $dif > 2100000 then
      MsgBox (48, "ATTENTION",$dif)
      MsgBox (48, "ATTENTION", "Process has timed out.")
      ProcessClose("notepad.exe")
      ExitLoop
   EndIf

  ; Progress Meter
   ProgressOn("PSTs Processing-Please be patient.", "DO NOT INTERRUPT THIS PROCESS.", "0")
   For $i = 10 to 100 step 10
      sleep(1000)
      ProgressSet( $i, $i & "")
   Next
   ProgressSet(100 , "", "")
   sleep(500)
   ProgressOff()
Until $procpstrunning = 0

You could try the following though:

dim $MaxTime, $StartSec

; Set the time out length here (in seconds)
$MaxTime = 0
$StartSec = @Sec
do 
   If @Sec = ($StartSec + $MaxTime) Then
     ; Loop timed out
      ExitLoop
   EndIf

   If $dif > 2100000 then
      MsgBox (48, "ATTENTION",$dif)
      MsgBox (48, "ATTENTION", "Process has timed out.")
      ProcessClose("notepad.exe")
      ExitLoop
   EndIf

  ; Progress Meter
   ProgressOn("PSTs Processing-Please be patient.", "DO NOT INTERRUPT THIS PROCESS.", "0")
   For $i = 10 to 100 step 10
      sleep(1000)
      ProgressSet( $i, $i & "")
   Next
   ProgressSet(100 , "", "")
   sleep(500)
   ProgressOff()
Until $procpstrunning = 0

Just remember to change the line $MaxTime=0 to $MaxTime=whatever timeout you want in seconds. I haven't tested it but the theory sounds clean to me. I hope this helps!

Hey Matt,

The DO and UNTIL...

The DO "progress meter" UNTIL the ProcessExits value= not exist works very well, and wil exit fine.

I excluded this Var set

$ProcPStRunning = Processexists ("notepad.exe")

But when I put the IF statement(as is example orignially posted) in, to timeout and exit loop it doesnt when Process ends early, but of course does when Timeout is reach. Will check your example.

Thanks Much..

I see now where you were attempting to do this, sorry I looked at it and just saw a couple msgboxes without looking at their content. I don't know what $dif contains though because it is not defined or initialized in the script you posted.

Looking at it now we may be doing the same things, but here is a new version with more understanding of the task:

dim $MaxTime, $StartSec

; Set the time out length here (in seconds)
$MaxTime = 0
$StartSec = @Sec
do 

   If @Sec = ($StartSec + $MaxTime) Then
    ; Loop timed out
      MsgBox (48, "ATTENTION",$dif)
      MsgBox (48, "ATTENTION", "Process has timed out.")
      ProcessClose("notepad.exe")
      ExitLoop
   EndIf

; Progress Meter
   ProgressOn("PSTs Processing-Please be patient.", "DO NOT INTERRUPT THIS PROCESS.", "0")
   For $i = 10 to 100 step 10
      sleep(1000)
      ProgressSet( $i, $i & "")
   Next
   ProgressSet(100 , "", "")
   sleep(500)
   ProgressOff()
Until Not ProcessExists("notepad.exe")

Hope that makes more sense.

Awesome Matt,

I actually wound up with the following. The Last line you added made a difference instead of relying on a variable. I got the Timerinit and Diff example from the help file and adapted it to this cause. Help file is awesome, but sometimes you need another Human Brain to put it all together.

Tested with Process closing before timeout, and tested with waiting for timeout. both worked.

Thanks again.

;Overall Variable Sets

;----------------------------------------------------------------------------------------------------

DIM $userprof = EnvGet("userprofile")

DIM $windir = EnvGet("windir")

;----------------------------------------------------------------------------------------------

; Starting Timer outside loop

Dim $begin = TimerInit()

Do

;Setting var(set happens each pass in loop) for time difference between this moment in script/loop and the timerinit set outside of loop.

$dif = TimerDiff($begin)

; Checking difference in loop and taking action if reached.

If $dif > 60000 then

MsgBox (48, "ATTENTION",$dif)

MsgBox (48, "ATTENTION", "Process has timed out.")

ProcessClose("notepad.exe")

exitloop

endif

; Progress Meter

ProgressOn("PSTs Processing-Please be patient.", "DO NOT INTERRUPT THIS PROCESS.", "0")

For $i = 10 to 100 step 10

sleep(1000)

ProgressSet( $i, $i & "")

Next

ProgressSet(100 , "", "")

sleep(500)

ProgressOff()

Until Not ProcessExists("notepad.exe")
