Use the standard "subprocess " module that comes in Python2.4.
Or, if you can't upgrade for some reason, it sounds to me
like os.popen() will do what you want... that's the older
standard technique.
No need to resort to lots of win32 stuff.

You'll need to pass security attributes with inherit=True
to CreateProcess also, and the file has to be opened with sharing.
(win32file.FILE _SHARE_READ|win 32file.FILE_SHA RE_WRITE)
Also, you shouldn't have FILE_FLAG_OVERL APPED set if you're
not passing an overlapped object into CreateFile.

If it got past the CreateFile call, the problem's not with the log file.
This error from CreateProcess means it can't find your executable.

Aweseome! Many many thanks Roger ! You've made my day.
The last thing that you may be able to help with...
I'm using
win32api.Termin ateProcess(hPro cess,3)
to kill this process if it gets outta hand...
but when i do so.. it seems that the stdout/stderr don't capture the
output.
here's my last chunk of code.
again.. thank you so much.
hProcess, hThread, dwProcessId, dwThreadId =
win32process.Cr eateProcess \
( None, self.RENDER_STR ING, sa, sa, 1,
win32con.NORMAL _PRIORITY_CLASS , None, None, startInfo)
while self.exitCode == 259:
if self.stop:
print "kill da process"
win32api.Termin ateProcess(hPro cess,3)
self.exitCode = win32process.Ge tExitCodeProces s(hProcess)
time.sleep(2)
TerminateProces s doesn't give it a chance to exit normally
and do any cleanup that would happen if it exited itself.
It may not have been able to flush its file buffers, etc.
Does the executable have any way to signal it to exit ?
