Hello All,
I've a batch file to be invoke using a python script. The batch file has
pause, and the time, I need to send some command to the batch file from my
scripts. I placed both, the batch file (test.bat) and the python script
(test.py) in the same folder. And executed 'test.py'
(Please find the source files and error below).
*I get the following error:*
Traceback (most recent call last):

WindowsError: [Error 6] The handle is invalid
*Python Script:*
*test.py*
import subprocess,os
my_bat = os.getcwd()+'\\test.bat'
proc = subprocess.Popen(my_bat,stdin=subprocess.PIPE)
input = '\n'
proc.communicate(input)
*Batch File*
*test.bat*
echo "START'
pause
echo 'END'
Please help me with this issue.
Thanks In Advance,
Tarun
subprocess.Popen() is expecting the name of a program, which should
normally have an extension of .exe You're handing it a .bat file,
which is not executable. It only executes in the context of a command
interpreter (shell), such as cmd.exe
You can probably do what you want by running "cmd.exe" and passing it
"test.bat" as a parameter
