Best way to read from powershell script?

4 posts in this topic

Hello,

Currently I am running a script that calls a powershell script. To read the results of that I am reading StdOut. I am parsing things accordingly but unfortunately it doesn't parse correctly all the time and I end up missing parts of the string or other problems. My question then is, what is the best results for reading what is returned when running a powershell script or something similar?

Example how I use PS to create a mailbox and write all messages from StdOut and StdErr to a log file:

$sCMD = "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -command . <command goes here>"
    $pid = Run($sCMD, @SystemDir, @SW_HIDE, $STDIN_CHILD + $STDOUT_CHILD + $STDERR_CHILD)
    StdinWrite($pid, @CRLF)
    StdinWrite($pid)
    ; Process STDOUT
    $sSTDOUT = ""
    While 1
        $sOutput = StdoutRead($pid)
        If @error Then ExitLoop
        If $sOutput <> "" Then $sSTDOUT = $sSTDOUT & @CRLF & $sOutput
    WEnd
    ; Process STDERR
    $sSTDERR = ""
    While 1
        $sOutput = StderrRead($pid)
        If @error Then ExitLoop
        If $sOutput <> "" Then $sSTDERR = $sSTDERR & @CRLF & $sOutput
    WEnd

Thanks for the help! My problem was that I was attempting to process each line from StdoutRead as it was happening. What worked for me was to do like what is in the example in the help file (of course!) and use $sOutput &= StdoutRead($pid). Now I just parse the $sOuput after the While Loop. Problem solved!

      Hi all,
      I need to read a log file into an array, but the log file is encoded as $FO_UTF16_BE_NOBOM (2048) = Use Unicode UTF16 Big Endian (without BOM) per FileGetEncoding (it returns 2048).
      I have searched how to convert these log files to UTF-8 and finally found a Powershell command. Since then I have been racking my brain trying to get the function to work. The command itself works from a Powerscript prompt:
      C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -Command Get-Content C:\Logs\Myplayer_10-10-17-02-31.log | Set-Content -Encoding utf8 C:\Logs\Myplayer1.log This is my sandbox;
      #include <array.au3> #include <File.au3> Local $aArrayLogFile Local $sLogDir = "C:\Logs\" Local $sLogFile = "Myplayer_10-10-17-02-31.log" Local $sConvertedLog = "ConvertedLog.log" Local $sLogDirFile = $sLogDir&$sLogFile RunWait("C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -Command Get-Content "&$sLogDirFile&" | Set-Content -Encoding utf8 "&$sConvertedLog,$sLogDir) _FileReadToArray($sLogDirFile, $aArrayLogFile) _ArrayDisplay($aArrayLogFile) Also tried
      RunWait("C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -Command Get-Content "&$sLogDirFile&" | Set-Content -Encoding utf8 "&$sConvertedLog,$sLogDir) and
      ShellExecuteWait("C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe"," -Command Get-Content "&$sLogDirFile&" | Set-Content -Encoding utf8 "&$sConvertedLog,$sLogDir) Tried without -Command and a bunch of other parameters that were sprinkled throughout the internet from people trying to get this to work.
      Thanks

      Howdy All
      I've gone around and around in circles wasting hours trying to fix this problem to no avail so I thought I would try posting for help given there are some real smart people in this forum.
      Background
      I have 5 separate .au3 scripts that all do different basic tasks. For example:
      1.au3 = opens Chrome browser to obtain information from a specific website then closes
      2.au3 = opens an Excel workbook to run a macro then saves and closes
      3.au3 = Open two seperate workbooks and transfers data from one to the other then saves and closes
      4.au3 = .......etc
      5.au3 = .......etc
      These 5 separate scripts, doing completely different tasks, need to each run once per day at 5 different designated times within a day and then close. For example:
      1.au3 = 10am
      2.au3 = 12pm
      3.au3 = 2pm
      4.au3 = 4pm
      5.au3 = 5pm
      Problem
      I can not get these different scripts to reliably run at their designated times. When I manually run these scripts individually by using 'Go F5' they work perfectly. If I convert these scripts to an .exe and manually run each one they work about 98% of time.
      How can I schedule these different .au3 files or associated .exe files to reliably run each day at different times?
      Attempts To Fix The Issue
      1. I have tried converting each .au3 script into their own .exe file and use Window's Task Scheduler to run these .exe files at their designated time but the success rate  of running each .exe in full, to completion, without error is very low at about 30%. Things that commonly go wrong include a browser not opening but movement still continues on the desk top. Other times things just do not happen at all.
      2. I have Windows 7 64 bit and have tried creating and running both (x86) and (x64) .exe files but again reliability problems exist;
      3. I have also tried moving each .exe file to the My Documents folder as I read someone that keeping your files on your desktop ties your files to individual Windows user profiles which can cause AutoIt operating errors. Not sure if this is correct but thought I would try it anyway. It did not fix my issue.
      4. I installed a program called AlwaysUp which supposedly always reliably runs in the background and will reliably execute your AutoIt script or .exe files. Still have significant reliability issues.
      Therefore, can someone please provide advice on how I can get my 5 different .au3 files to run at 5 designated times through the day, every day, without fail? Overtime I will be creating more and more different .au3 files to run certain tasks throughout the day and do not want to create one large AutoIt file that continually runs and attempts to do all the different tasks itself.
      Any help is very appreciated.
      Thanks
      Dan

      Hi all,
      I built an AutoIt application that interacts with several other applications/software. Now, it's turn to interfact with Visual Studio Team Services (VSTS).
      Does anyone has a blog, demo, script to share?
      Thanks!

      This is my first time here so please dont bombard me that what a silly question I am asking!!
      I have 500 rows (A1:A500) in a spreadsheet and I just want to copy one by one row and then paste into another application and then press enter, loop should repeat this until finishes all 500 rows.
      I have looked at clipget(), clip(put() but dont know how to select next row in next turn. I also looked at Array to store but again no luck. Can some guide me please..
