Log off option

Hi Guy

I want to add a function to a tool that I have to disable the log off option from windows XP and 2000, this tool is designed to update programs installed on the users machine, and after the update the user need to reboot their machines. the only thing that will kill the reboot screen after the update is done, its either by END TASK from the list of the processes or when the user chose to log off.

1- How can I disable the user from killing the tool when they log off?
2- Or can I add an option if the user chose to log off this will triger another EXE file that will warn the user or will stop the log off process?

Thanks

Disabling log off is not recommended as it is a dominant call your program should be rethought and act within the constraints. For instance if the user inplicitly wants to log off then your program stopping the user from doing it a fustration to the user.

Better to use query unload to save the status of the program then continue when the computer is logged back in.
