End process challenge
Dear experts,
I have a task to write a program that will be started
from the registry (Run) and ended with the Shut Down. The
problem is that I need to end the execution of the program gracefully, as it will do a lot of calculations, it needs
to save its data before the Shut Down.
It'd be also great if there was a way to save all data when user tries to terminate the process from the Task
Manager.
The program should be able to run on most Windows platforms.
I appreciate your help.

If it is a GUI app: Process 'WM_ENDSESSION' and 'WM_QUERYENDSESSION'

Actually, my app is an API executable that runs without any windows. On Terminate Process from Task Manager
it doesnt seem to receive any messages, nor at Shut Down.
Is there still a way to capture those messages?
I would've implemented this app as a Service, but my goal was to make it run on most Windows platforms.

First of all, I would abstract my startup and shutdown, and actually make it a service on nt/2k/xp. Secondly, on win9x, I think what you can do is create a window which is not visible. That should allow you to catch the messages that you will need. There's more info here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sysinfo/base/system_shutdown.asp

Thanks, Brian, that helped.
What about when a user tries to end the process from the Task Manager? I suppose no messages get posted in this case, right?
