Reading from a child process

[Ravi1stop]

I am launching an interactive session with an application using the run command. The application stays active till the exit command is given. I can see the responses from the application in the debug window but cannot figure out how to get that data into the code so that I can detect that the process has been completed. here is the code

#include <constants.au3>

global $fname
$fname="11-6-11"

Run("c:program files3d3solutionsflexscan3d 3flexscan3d.exe interactive ","","",$STDIN_CHILD())
sleep(10000)
Global $PID = ProcessExists("Flexscan3d.exe")

StdinWrite($PID,'scriptline set("Scanning_WidePhase_Enabled","True") n'&@CRLF)
sleep(2000)
StdinWrite($PID,"scriptline scan() n" &@CRLF)

sleep(5000)


StdinWrite($PID,"exit" &@CRLF)
 

Here is the output:
>Running:(3.3.8.1):C:Program Files (x86)AutoIt3autoit3.exe "C:UsersNew AdministratorDesktopscriptflexscan.au3"    
--> Press Ctrl+Alt+F5 to Restart or Ctrl+Break to Stop
:interactive
<< scriptline set("Scanning_WidePhase_Enabled","True") n
>> :done scriptline set("Scanning_WidePhase_Enabled","True") n
<< scriptline scan() n
>> :done scriptline scan() n
+>14:39:30 AutoIt3.exe ended.rc:0
>Exit code: 0    Time: 18.978

 

Rather than use the sleep function and hope the process gets done in time, I would like to wait till the process is actually complete.

Thanks

I think you need to look up StdoutRead in the help.

My apologies for being relatively new at this. I did try the Stdoutread the best I could looking at the limited examples from the forum with not much success. There are not a lot of examples for it and my programming skills are unfortunately not very good. Appreciate any assistance or guidance.

Thanks

It doesn't matter if you get it wrong, but the help for stdoutread has an example, so could you try applying that then tell us what, if anything happens and then we can build from there.

Hi Ravi1stop

to catch the output from a dos program you have to run it with the $STDOUT_CHILD parameter and then use StdoutRead() to get the output

>here I posted some examples

Bye

Thank you I have it figured out now. May not be the best code but it works.

 

#include <constants.au3>

global $fname
$fname="11-6-11"

Run("c:program files3d3solutionsflexscan3d 3flexscan3d.exe interactive ","","",$STDIN_CHILD()+ $STDOUT_CHILD())

Global $PID = ProcessExists("Flexscan3d.exe")
check_std()
StdinWrite($PID,'scriptline set("Scanning_WidePhase_Enabled","True") n'&@CRLF)
check_start()
check_end()
;sleep(2000)
StdinWrite($PID,"scriptline scan() n" &@CRLF)
check_start()
;sleep(5000)
check_end()


StdinWrite($PID,"exit" &@CRLF)

Func check_std()
    Local $line

while 1
    $line = StdoutRead($PID)
    if StringLen($line)> 8 then ExitLoop
WEnd
EndFunc
Func check_start()
    Local $line2

while 1
    $line2 = StdoutRead($PID)
    if StringLen($line2) > 10 then ExitLoop
WEnd
EndFunc
Func check_end()
    Local $line2

while 1
    $line2 = StdoutRead($PID)
    if StringLeft($line2, 8) = ">> :done" then ExitLoop
WEnd
EndFunc

; Finished!
