Help running an exe with parameters and redirection

[jesternaut]

I have an executable with a parameter that I need to run to get the response text. I redirect it to a text file then I use filereadline to read in each line and stringInStr to look for the string "Changer". but when I run this the tapetest.txt is not generated. I don't think the parameter is being read. If I run the exectable and the parameter in a shell it works.

I have tried the shellexecute, and the run commands using the @stdio_child. I have gone so far as to create a bat file that runs the shell commands when called and called it via a run command inside the script. If I run it in a shell it runs but not from the Autoit script.

The code is...

Func is_changer()

; this function checks if a changer is connected

;This will generate a file with the output from the ca_devmgr -adapterinfo command

RunWait("C:\Program Files\CA\BrightStor ARCserve Backup\ca_devmgr -adapterinfo > tapetest.txt")

MsgBox(0, "check point 1:", "Is the tapetest.txt there")

$file = FileOpen("C:\Program Files\CA\BrightStor ARCserve Backup\tapetest.txt", 0)

; Check if file opened for reading OK

If $file = -1 Then

MsgBox(0, "Error", "Unable to open file.")

Exit

EndIf

; Read in lines of text until the EOF is reached

While 1

$result = "" ;reset result back to blank

$line = FileReadLine($file)

If @error = -1 Then ExitLoop

;MsgBox(0, "Line read:", $line)

$result = StringInStr($line, "Changer")

If $result <> 0 Then ;if true means a changer was found

$changer = "0" ;0 indicates the changer exists

MsgBox(0, "changer found:", "The $changer result is " & $line)

ExitLoop

EndIf

Wend

FileClose($file)

FileDelete("C:\Program Files\CA\BrightStor ARCserve Backup\tapetest.txt")

; Shows the GUI after the function completes

GUISetState(@SW_SHOW)

EndFunc

I would love a simpler way to get the response from the executable. But when I run this the tapetest.txt is not generated.

Try it this way and see if that isn't a little easier:

#include <Constants.au3>

Local $sDir = "C:\Program Files\CA\BrightStor ARCserve Backup"
Local $sExe = "ca_devmgr -adapterinfo"
Local $sOutput = ""
Local $PID = Run($sDir & "\" & $sExe, $sDir, @SW_MINIMIZE, $STDOUT_CHILD + $STDERR_CHILD)
Do
    Sleep(20)
    If StdoutRead($PID, 0, 1) Then $sOutput &= StdoutRead($PID)
    If StderrRead($PID, 0, 1) Then $sOutput &= StderrRead($PID)
Until Not ProcessExists($PID)
If StringInStr($sOutput, "changer") Then
    MsgBox(64, "Changer Detected", $sOutput)
Else
    MsgBox(16, "No Changer Detected", $sOutput)
EndIf
