Autoit sometimes freezes when polling StdOutRead

[daledale]

How I searched for the hang-up place. I changed the code as follows.

; freezes randomly
#include <Date.au3>
#include <Constants.au3>

local $fDiff=0, $pid=0, $hTimer=0, $line=""

While 1
    ConsoleWrite('1 '&_NowTime()&@CRLF)
    $pid = Run("ipconfig", "", @SW_HIDE, 0x2)
    $line = ""
    ConsoleWrite('2 '&_NowTime()&@CRLF)
    $hTimer = TimerInit()
    While 1
        $fDiff = TimerDiff($hTimer)
        $line &= StdoutRead($pid)
        If @error or $fDiff>50 Then ExitLoop
    Wend
    ConsoleWrite('3 '&_NowTime()&@CRLF)
    if StringInStr($line,'0.1'&@CRLF)>1 then TraySetIcon("icon1.ico")
    if StringInStr($line,'0.2'&@CRLF)>1 then TraySetIcon("icon2.ico")
    ConsoleWrite('4 '&_NowTime()&@CRLF)
    sleep(20000)
    ConsoleWrite('5 '&_NowTime()&@CRLF)
WEnd

In general, in all cases of freezing, the last thing printed was, for example:

2 07:08:09

Something like that.

@daledale  I think your issue comes from the fact that you are not waiting for the stream to be ready to transmit correctly.  You should wait for the process to be up and running before reading the stream.  Here the right way to get the result of ipconfig.

#include <Date.au3>
#include <Constants.au3>

Local $pid, $line

While True
  ConsoleWrite('1 ' & _NowTime() & @CRLF)
  $pid = Run("ipconfig", "", @SW_HIDE, $STDERR_MERGED)
  ConsoleWrite('2 ' & _NowTime() & @CRLF)
  ProcessWaitClose($pid)
  $line = StdoutRead($pid)
  ConsoleWrite('3 ' & _NowTime() & StringLeft($line, 50) & @CRLF)
  ;If StringInStr($line, '0.1' & @CRLF) > 1 Then TraySetIcon("icon1.ico")
  ;If StringInStr($line, '0.2' & @CRLF) > 1 Then TraySetIcon("icon2.ico")
  ConsoleWrite('4 ' & _NowTime() & @CRLF)
  Sleep(2000) ; reduced sleep to get more occurences
  ConsoleWrite('5 ' & _NowTime() & @CRLF)
WEnd

Thanks for the answer. I don't want to challenge your competence in any way. I think when you wrote that "the stream is not ready to transmit" - you mean that the command RUN was not completely finished. If so, I want to focus your attention to - what is printed last, when it hangs (see my reply above).

This is not worked for me. I need gateway's ip from ipconfig. The above version of the program with ipconfig output does not do this, $line variable does not contain any ip addresses at all.

ps I hope you saw the beginning of my reply on the previous page? There I provided three programs, one of which definitely works for me and overall my problem is solved. I just wanted to share a possible solution with the forum members. Now I don't have any problem related to this and my issue is, I repeat, solved.

Fine, I just want to state (for any future readers) that the way you are doing it is not appropriate and they (future readers) should use my method instead.

I have no idea why it does not work for you and with your attitude I will not investigate further the reason.

Here what $line content in my case :

Nothing against it, the choice is up to the end users. I don't insist on my decision exclusively.

Checked again, your option really doesn't work for me. Again, I have win7x64 (maybe you have win10,11 and that's the reason) and also maybe the reason is that I do NOT have an English language windows.

I'm sorry. I translate all my replies with a translator - I wrote earlier. Perhaps there are some difficulties in translation and you thought I insulted you. I apologize again.

There is a stringleft (as I didn't want to show everything on every cycle).  Remove the stringleft and you will be fine !

Yeah, it's working now. Thank you.

ps Strange that I didn't realize it right away, indeed, stringleft)))
