Execute program during certain Windows® events.?

Question

I have a program that I made that I want to use when you get to the Windows® login screen, when you return from screen saver, and when you lock your computer. The program asks for a set password. Is there any way to have the program run at the certain events?

I know you can ask for password on screen saver resume, but I want to interrupt the login process.

Answer 1

yea i guess so
u make ur program calls in the ISR"interrupt service routine"

Answer 2

That feature is already built in! Go to your screensaver tab and look at the box "on resume, password protect". Just check the box.
