Win XP: How to hide command window for sub processes?
Hi, I have a Python script which wants to start a subprocess and wait for it to finish. However I would like to have NO command window popping up during execution. My main Python script is started with the .pyw suffix, thus I got rid of the main console and I just see my GUI. So far I tried os.system() and subprocess.call() with os.system() the command window pops up and I see my commands output. with the subprocess.call() and stdin ./ stdout / stderr redirection I manage to get rid of stdout/stderr ( redirecting to the file 'NUL:' ) but the window stays. the subprocess is a call to a .exe file with multiple parameters. I would appreciate any hints bye Klaus -- http://mail.python.org/mailman/listinfo/python-list

You need to specify the hide parameter for windows.
import subprocess
kwargs = {}
if subprocess.mswindows:
su = subprocess.STARTUPINFO()
su.dwFlags |= subprocess.STARTF_USESHOWWINDOW
su.wShowWindow = subprocess.SW_HIDE
kwargs['startupinfo'] = su
process = subprocess.Popen( (r'c:\python25\python.exe',
r'd:\projekte\bar.py'), **kwargs )

if subprocess.mswindows:
su = subprocess.STARTUPINFO()
su.dwFlags |= subprocess.STARTF_USESHOWWINDOW
su.wShowWindow = subprocess.SW_HIDE

process = subprocess.Popen( (r'c:\python25\python.exe',
r'd:\projekte\bar.py'), **kwargs )
Interestingly, none of that appears to be documented. I smell a docs
bug waiting to be reported.
Cheers,

I was referring to the following bits of the subprocess module used in
the above code:
subprocess.mswindows
subprocess.STARTUPINFO()
subprocess.STARTF_USESHOWWINDOW
subprocess.SW_HIDE
none of which are mentioned in the module's docs:
http://docs.python.org/dev/py3k/library/subprocess.html

Chris

True, the Windows APIs are documented but it's not mentioned at all that they're accessible in a certain form from subprocess. Many other stdlib modules (e.g. `os` - http://docs.python.org/library/os.html) include and list platform-specific functions, I don't see why subprocess should be different.

Thanks Ruediger,
I'll try that immediately tomorrow, when working again on a windows
host.
Good to know, that the Python API supports this.
though this feature was not that easy to be found in the doc.
This will make my application much nicer.
