how to terminate a process on win32?

[Joe Wong]

Hi,

I am developing two app on Windows, one is a GUI using wxPython and the other is like a daemon process. The GUI app will have a start/stop button to control the excution of the daemon. While I know how to use os.popen2() to start my daemon, I can't figure out a way to stop it 'nicely'... Is there anything that I can do?

Regards,

You can use the win32process.TerminateProcess function to kill a
process... see the win32 docs

It depends on your OS. I remember once upon a time, in order to kill
processes sucessfully for all Windows platforms (from Win98 to NT to
2000/XP), I had to resort to using tlist.exe and kill.exe, plus
w9xpopen.exe for pipes in Windows 98. It was kind of annoying... I
seem to remember short name and long names were problem, too. At the
end, the killing logic became a small program in itself!

Mark Hammond's Python for Windows extensions includes a demonstration
of killing processes on Windows:

On my PC:
C:\Python23\Lib\site-packages\win32\scripts\killProcName.py

Python for Windows extensions:
http://starship.python.net/crew/mhammond/
https://sourceforge.net/projects/pywin32/

But calling TerminateProcess will stop the application right away. I need
someway that the process being killed get notified and thus to carry out
some procedure before shut down. On Linux, I can use kill(pid, signum) to
achive this but on windows?
