      Good morning,
      I am trying to read a Unicode utf8 string from a perl subprocess via StdoutRead.
      I use an AUtoIt GUI and display result in an 'Edit' control (see my code below) using 'Courier New', a font that can handle Unicode characters.
      I was expecting a result looking like (CMD console):
      ++$ chcp 65001>NUL: & perl -Mutf8 -CS -e "use 5.018; binmode STDOUT,q(:utf8); say qq(\x{03A9})" & chcp 850>NUL: Ω Instead I get someting like this (see downward the screen copy):
      ++$ chcp 1250>NUL: & perl -Mutf8 -CS -e "use 5.018; binmode STDOUT,q(:utf8); say qq(\x{03A9})" & chcp 850>NUL: Ω Obviously while I was expecting to receive an utf8 char, it seems to have been converted to Windows ANSI codepage 1250 (Windows default for Western/Central Europe, right ?)
      What am I doing wrong? Is there someone who could guide me?
      Here is my code and my output in the GUI.
      Creating and configuring the Edit control:
      Local $Edit1 = GUICtrlCreateEdit( "", 20, 110, 780, 500, BitOr($GUI_SS_DEFAULT_EDIT,$ES_MULTILINE,$ES_READONLY) ) GUICtrlSetData($Edit1, "This field will contain text result from external Perl command") GUICtrlSetFont($Edit1, 10, $FW_THIN, $GUI_FONTNORMAL, "Courier New")  
      Executing Perl command (note: `-Mutf8` and `-CS` garantees that I work in utf8 and STDOUT accepts wide-characters):
      local $ExePath = 'perl.exe -Mutf8 -CS ' ;~ if perl in PATH, no need for full path C:\Perl\bin\perl.exe local $Params = '-e "use 5.018; use utf8; use charnames q(:full); binmode STDOUT,q(:utf8);' & _ 'say scalar localtime; say qq(\N{GREEK CAPITAL LETTER OMEGA})"' local $Cmd = $ExePath & ' ' & $Params Local $iPID = Run($Cmd, "", @SW_HIDE, BitOR($STDERR_CHILD, $STDOUT_CHILD))  
      Reading STDOUT and displaying it into the Edit control:
      While 1 $sOutput &= StdoutRead($iPID) If @error Then ; Exit the loop if the process closes or StdoutRead returns an error. ExitLoop EndIf WEnd If $sOutput <> '' Then GUICtrlSetData($Edit1, $sOutput) EndIf  
      And now, what I get on my GUI:

        I would like to be able to write a script to send commands to the console for creation of Gstreamer pipelines.  I was thinking of something similar to this:
      Local $iPID = Run("C:\Windows\System32\cmd", "", @SW_MAXIMIZE) ;THIS OPENS THE CONSOLE...!!! if $iPID == 0 Then ConsoleWrite(@CRLF & "I DID NOT OPEN CMD...error: " & @error & @CRLF) if $iPID <> 0 Then ConsoleWrite(@CRLF & "I OPENED CMD...!!!" & @CRLF) $hCmd = WinGetHandle("C:\WINDOWS\system32\cmd.exe") if $hCmd <> 0 Then WinActivate($hCmd) ;ensure command console is active... $sOutput = Send("cd C:\gstreamer\1.0\x86_64\bin" & @CRLF, $SEND_RAW) $sOutput = Send("gst-launch-1.0 videotestsrc ! autovideosink" & @CRLF, $SEND_RAW) Sleep(3000) ControlSend($hCmd, "", "", "exit" & @CR) EndIf ;$hCmd NOT "0"... I don't really know if this is the best way to open the console and send commands into it.  I'm also not sure about how to best catch any errors that may occur...likely this needs to be accomplished with the STDOUTREAD command however I've not had experience using it before and therefore would appreciate some advice that anybody may offer. 
      Basically I'm seeking guidance on how to best automate the opening of the console, sending lines of commands to be executed, and handling any potential errors in the execution of those commands...I thank you in advance.  Regards.

      I have a Parent Script that starts multiple, concurrent child processes. I cannot figure out how to apply the technique for using StdoutRead in the examples in a way that listens to them all simultaneously.
      For reference, there can be any even number of, or single, child processes and there is an 1D array, $PIDS, that stores the PIDS of all the child processes and they should be outputting to another 1D array $sOutput.
      Thank you for your time. Please just point me in the right direction. I'm sorry if I missed another topic that covers this.

      Here is a small library (UDF) that I use all the time. Not transcendent, it’s just to simplify my life.
      When I use the ConsoleWrite function, more than 99.99 percent, I go to the line (Newline), more than 99.99 %, parameters à the same except information that i exam. _CW is born.
      The second one _CW_Fmt allows to display marks (Fmt for Formatting) and allows to evaluate the format the length of a variable and the position of some characters without counting too much :-).
      For the functions derived from MsgBox () again the same observation, always the same parameters following the context: Info, Error or Warning. Thus were born _MB_Info, _MB_Error and _MB_Warning.
      As for _MB_IsOk, the same observation about the logical answer we are interested in a question with two choices: agree or disagree and not much else (True or False).
      All your remarks, suggestions and constructive criticism are welcome.

      Hey Guys,

      I have a (i think) simple question, but i can't seem to get the answer though the help-files.
      Hope that you can help me with this issue.
      - I am opening a SSH Connection with the following function
      Func _Connect($session,$usr,$pass) $exec = @ScriptDir & "\PLINK.EXE" If Not FileExists($exec) Then _Err("PLINK.EXE Not Found!",0) $pid = Run($exec & " -load " & $session & " -l " & $usr & " -pw " & $pass, @ScriptDir, @SW_HIDE, 0x1 + 0x8) ;Run SSH.EXE If Not $pid Then _Err("Failed to connect",0) $currentpid = $pid ;$rtn = _Read($pid) ;Check for Login Success - Prompt ;MsgBox(48,"","1") ;sleep(5000) ;Wait for connection Return $pid EndFunc - This will connect to a CMS Server with a vt100 interface where a dynamic report is generated every 20 seconds.
      - Then i will read the contents with the following Function
      Func _Read($pid) $SSHREADTIMEOUT = 0 If Not $pid Then Return -1 Local $dataA Local $dataB Do $SSHREADTIMEOUT += 1 $dataB = $dataA sleep(100) $dataA &= StdOutRead($pid) If @error Then ExitLoop Until ($dataB = $dataA And $dataA And $dataB) OR $SSHREADTIMEOUT == 50 Return $dataA EndFunc This all goes correctly, but i can only read the contents once.
      When i try to read the contents again i get nothing.
      Maybe because the CMS isn't changing, but the values in the report is changing every 20 seconds.
      I need to somehow read al of the contents every time i perform a Read action, but how?
      Yes, i can use it in a While loop, but also then i get nothing or a small line of text and not the whole report.
      Any Idea?
      Thanks Guys!
      I have fixed the problem by changing the terminal session to a vt220 session.
      The only problem now is that i want to send the: "Data link escape" command and that is something i cannot fix,.
      I have tried;
      StdinWrite($Pid,Hex(0x10)) StdinWrite($Pid,Chr(16)) StdinWrite($Pid,{DLE}) But nothing seems to work.  
      -- Edit-2 --
      Guys, fixed that too!
      Forgot to add the number '5' to actually execute the assignment.
      So fixed it by using;
      StdinWrite($Pid,Chr(16)) StdinWrite($Pid,"5")
      Thanks for reading with me
