Re: [Py2exe-users] Starting 3 Programs from One Shell

Hi Mike,

Start your programs using the 'subprocess' module. It has a couple of
very easy to use convenience functions and should be easier to use than
either os.popen or os.system.

(I recently was faced with a similar problem, but my need to stop using
os.system was that the shell started by os.system cannot change to UNC
network paths, and the software I need to run - from my
py2exe-executable with wxPython GUI - is installed on a network volume)

Success,

Subject: [Py2exe-users] Starting 3 Programs from One Shell

=20

I've created a wxPython launcher GUI, converted with py2exe, that starts
3 other programs. However, it also starts up three shell windows as
well. My boss wants me to reduce the number of shell windows to 0 or 1.

    Currently, my program starts them using:
os.system("start \B [program name & arguments")

    And I convert it to an exe using this setup.py script:
# setup.py
from distutils.core import setup
import py2exe
setup(windows=3D["launcher.py"], zipfile=3DNone)

    I've tried changing windows to console; that works (it only opens up
one shell), but it also removes all graphics/text from the GUI. I'm
thinking of trying:
1. Setting it to console, but importing certain wxPython libraries, or
2. Upgrading to subsystem commands and tacking on the CREATE_NO_WINDOW
flag.
Option 2 looks like my best bet, but I'm unsure if the spawned programs
will still run if the launcher's killed. (They need to.)

Any suggestions on how I can reduce the number of shells?
