If you are running win32-only you might as well use win32api. That way you can do pretty much whatever you want.
For reference, attached is parts of some code I used a while ago.
from __future__ import nested_scopes
import win32process
import win32event
import win32api
import win32con
import win32pdhutil
class ProcessUtil:
def create(self, cmd, rect=None):
si = win32process.STARTUPINFO()
if rect == None:
# No position given. Place in upper right corner, use 1/4 of screen size
si.dwX = 0
si.dwY = 0
si.dwX = win32api.GetSystemMetrics(win32con.SM_CXSCREEN) / 2
si.dwY = win32api.GetSystemMetrics(win32con.SM_CYSCREEN) / 2
else:
si.dwX, si.dwY, si.dwXSize, si.dwYSize = rect
si.dwFlags = win32process.STARTF_USEPOSITION | win32process.STARTF_USESIZE
self.pinfo = win32process.CreateProcess(None, cmd, None, None, 0, win32process.NORMAL_PRIORITY_CLASS, None, None, si)
self.handle = self.pinfo[0]
self.created = 1
def createAndWait(self, cmd, timeOut=-1):
self.create(cmd)
self.waitForProcess(timeOut)
def waitForProcess(self, timeout=-1):
"Wait for a process to terminate. If process is not terminated within given time, terminate it"
if self.created:
rc = win32event.WaitForSingleObject(self.handle, timeout)
if rc != win32event.WAIT_OBJECT_0:
self.terminate()
#self.running = 0
else:
rc = win32event.WaitForSingleObject(self.handle, timeout)
if rc != win32event.WAIT_OBJECT_0:
print "Process timed out"
def terminate(self):
"Terminate running process"
if self.created:
rc = win32process.TerminateProcess(self.handle, 0)
self.created = 0

Subject: [wxPython-users] Launch windows batch file from wxPython (2
requirements)
I want the following to happen when I launch a windows bat file from
wxPython:
1) No "dos-window" should appear on the screen.
2) My GUI should wait until the bat file finish.
So far I'm only able to satisfy 1 of the requirements:
os.system('my.bat > nul')
os.spawnv( os.P_WAIT, 'my.bat', ('my.bat',' > nul') )
dump = os.popen( 'my.bat' )
The first two waits for the process to finish, but display the anoying
dos-window.
The last one does not display the dos-window but don't wait for the bat file
to complete.
Is there a third option? Can Python/wxPython handle both requirements at the
same time?
Thanks for any help!
Jens
