Program execution when quitting windows

[cpoore]

I have an application that runs from the Windows Startup menu so it executes when the user logs in and terminates when the user logs off. This application periodically saves changes the user makes to a database whenever they perform certain actions. However, I want to make sure all the user's changes are saved when they log out of windows.

How can my program detect that the user is logging out and force windows to wait until the program has made it's database updates?

I am using Windows XP Pro and CVI version 8.1

Thank you

Hi cpoore,

you may find useful reading this thread, especially the last post from ovrabek/CZ which explains how you can refuse to close the system so to let your program terminate all necessary shitdown actions.

>>terminate all necessary shitdown actions

Typos are a fact of life.  thanks for this one as it made me laugh hard.

That's scary, I read it without even noticing the typo until you pointed it out ...

I had never been able to get shutdown message detection to work with the message callback either.  Is the sum of this then that if the callback returns a 1, the close event is truly swallowed by the callback?

Thanks for the link. I'm going to go SITdown and try it out.
