write return value of exe call to text file

[olmanRvr]

I have a compiled script :-timeStampSecs.exe which returns timestamp in seconds. I call it in FileWrite to write the time stamp in a text file.But it writes some other values instead of the timestamp. Please help.

thanks

olmar

The script is below:-

$kNum=run("timeStampSecs.exe","",1); also tried with flags 2,4,8,10
$hFile=FileOpen("timeStamp.txt",2)
FileWrite($hFile,"the key is: "&$kNum)
FileClose("$hFile")

;Code of thetimeStampSecs.exe:-
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

#include <Date.au3>

Func secFromEpoch()
Local $ts=_DateDiff( "s","1970/01/01 00:00:00",_NowCalc())
    $ts=String($ts)
    ConsoleWrite("timeStamp is: "&$ts&@CRLF)
        Return $ts
EndFunc
secFromEpoch()

olmanRvr,

Look at the help file for run.  RUN returns the PID if successful.  If you want to write the time stamp to a file you will have to do that in the script that calculates it.  You can pass in a file name as a command line parameter if you wish.

Hi, Thanks for the quick reply.Let me try your suggestion .Will let you know

olmanRvr,

Or you can read the return stream of the process like this:

#include <AutoItConstants.au3>
#include <MsgBoxConstants.au3>

Local $iPID = Run("timeStampSecs.exe", "", @SW_HIDE, $STDOUT_CHILD + $STDERR_CHILD)
Local $sOutput
While 1
    $sTemp = StdoutRead($iPID)
    $sTemp &= StderrRead($iPID)
    ; Exit the loop if the process closes or StdoutRead returns an error.
    If @error Then
        ExitLoop
    Else
        $sOutput &= $sTemp
    EndIf
    Sleep(10)
WEnd
MsgBox($MB_SYSTEMMODAL, "Stdout Read:", $sOutput)

Or simply use RunWait()?

FileClose("$hFile")

should rather be 

FileClose($hFile)

just a typo though.

When calling command line executables I quite often have more succes using:

Run(@ComSpec & " /c " & ...)

 

[olmanRvr]

Instead of Run used RunWait as per Jos .Same issue--- writing PID numbers in place of the time stamp as wanted.Also removes quotes from fileclose  like "$hFile"-->$hFile but doesn't help.

Working on reading the return stream(as per Melba23's suggestion).

 

see you.........

[olmanRvr]

Read stream of  run call to timeStampSecs.exe .But still getting blank output(in consoleWrite.See code below:--

#include <AutoItConstants.au3>
#include <MsgBoxConstants.au3>

Func readStream()
            Local $iPID = Run("timeStampSecs.exe", "", @SW_HIDE, $STDOUT_CHILD + $STDERR_CHILD)
        Local $sOutput
        While 1
            $sTemp = StdoutRead($iPID)
            $sTemp &= StderrRead($iPID)
            ; Exit the loop if the process closes or StdoutRead returns an error.
            If @error Then
                ExitLoop
            Else
                $sOutput &= $sTemp
            EndIf
            Sleep(10)
        WEnd
        MsgBox($MB_SYSTEMMODAL, "Stdout Read:", $sOutput)
        ConsoleWrite("ts is: "&$sOutput&@CRLF)
        Return $sOutput
EndFunc
readStream()

Nah, RunWait() returns the Returncode of the shelled program.

olmanRvr,

The  StdoutRead code worked for me with a compiled version of the script you posted in the OP, as did Jos' suggestion.

olmanRvr,

Works perfectly for me like this (M23 code modified)...

#include <AutoItConstants.au3>
#include <MsgBoxConstants.au3>

Local $iPID = Run(@scriptdir & "\timeStampSecs.exe", "", @SW_HIDE, $STDOUT_CHILD + $STDERR_CHILD)
Local $sOutput
While 1
    $sOutput &= StdoutRead($iPID)
    If @error Then ExitLoop
    Sleep(10)
WEnd
MsgBox($MB_SYSTEMMODAL, "Stdout Read:", $sOutput)

Hi kylomas,

Tried the code  you have shown.Yes, it is showing the timestamp in  a GUI window.Problem arises when I  add  the following line:-

ConsoleWrite("value is: "&$sOutput&@CRLF)

ConsoleWrite fails to write the value.Same issue occurs when writing the value of  $sOutput to a text file.Weird thing is if I replace the 

timeStampSecs.exe with  genKeyNum.exe it works fine !! Any idea, anyone please?

example below:

;Only difference to the previous function is that another  exe file is invoked
Func runExegenKeyNum();the exe fetches the physical drive number
        Local $iPID = Run(@scriptdir & "\genKeyNum.exe", "", @SW_HIDE, $STDOUT_CHILD + $STDERR_CHILD)
        Local $sOutput
        While 1
            $sOutput &= StdoutRead($iPID)
            If @error Then ExitLoop
            Sleep(10)
        WEnd
        MsgBox($MB_SYSTEMMODAL, "Stdout Read:", $sOutput)
        ConsoleWrite("value is; "&$sOutput&@CRLF)
        Return $sOutput
EndFunc
 runExegenKeyNum()
 ;XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
 ;code for genKeyNum.exe
 
 Func gtSrNo()
        $wbemFlagReturnImmediately = 0x10
        $wbemFlagForwardOnly = 0x20
        $colItems = ""
        $strComputer = "localhost"
        Global $Output=""
        $objWMIService = ObjGet("winmgmts:\\" & $strComputer & "\root\CIMV2")
        $colItems = $objWMIService.ExecQuery("SELECT * FROM Win32_DiskDrive", "WQL", _
        $wbemFlagReturnImmediately + $wbemFlagForwardOnly)
    For $oItm In $colItems
        $Output = $Output & $oItm.SerialNumber & @CRLF
    Next
        ConsoleWrite($Output&@CRLF)
    Return $Output;$Output is the serial; number
EndFunc

Sideways offer: why not including the various function in the main script instead of invoking them compiled as as many executables?

[olmanRvr]

Hi,

I would hard code these values(Hd srnum&timestamp) into the code for each user, basically to bind it to a single machine for a predefined period.Hence in the last moment, after user clicks download button,these values are fetched and incorporated into the script & then compiled .Which will, then be downloaded.

But thanks for your reply
