Re: How to spawn a windows process without blocking?

[David Morris-Oliveros <david.morrisoliveros@...>]

You can call "start" first:

os.execute('start "window title" "notepad.exe"')

The problem with start.exe is that the first quoted parameter is the 
title of the window, so, doing this:

os.execute('start "c:\\full path\\to\\notepad.exe"')

Will open up a console window with the title bar as "c:\\full 
path\\to\\notepad.exe", so, you have to put whatever infront of it, it 
can just this:

os.execute('start "blah" "c:\\full path\\to\\notepad.exe"')

HTH.
