How to detect windows shutdown

[Austin]

I wrote a program running on windows.
I put the link of the program in "Start up" folder and let it executed
minimized.
Every time when I open the computer, my program will be running in system
tray.

But if the user would like to shutdown the computer, the OS will show an
error about exception.

At first, I think windows will terminate all processes when it shutdown.
So, if python has the way to dectect shutdown process, I can kill the
process in advance.

Thanks a lot.

Programs that start at boot, run until shutdown and run in
background all the time under Windows are good candidates
for being turned into Windows Services. They respond to
shutdown commands properly and can be fine-grained scheduled
as well. For tutorial pick of a copy of Python Programming
on Win32 (Hammond and Robinson) and use Mark Hammonds Python
Windows extension library.

Important missing information: is this a GUI program or
a console program, and if it's a GUI program, what framework
did you use to write it (wxPython, PyQt, other...)? Also,
what is the exception that you got? (Always report the
specific error: we can't guess what exception you got,
and the answer could well point directly to a cause that
is different than you think it is.)

I wrote a GUI program with wxPython.
The error message is:

Unhandled exception
An unhandled exception occured. Press "Abort" to terminate the program,
"Retry" to exit the program normally and "Ignore" to try to continue.

Actually, besides the main program, there is another thread running
background.

Does this problem also occur when you "manually" exit the program (provided
you have a function to do so)?

If so, make sure you do something like self.tbicon.Destroy() -- with
self.tbicon being your instance of wx.TaskBarIcon() -- in your
event handler bound to wx.EVT_CLOSE.
