Simulating mouse or keyboard inputs

[Robert34]

I have a program that runs indefinitely without any user inputs.  There are some scheduled OS activiities that want to kick in every few minutes like the screen saver or the monitor power shutdown.  Is there a way for a program to simulate a mouse or keyboard input every once in a while to make the OS think there has been a user input and prevent these scheduled activites?

Thanks,
Robert

Well, you could always have your program turn off the screensavers etc using the SystemParametersInfo API in the User32.dll.

But you can also simulate mouse movement using the MouseEventEx API in the User32.dll.  I was just looking at a sample for this somewhere on my system yesterday, but for the life of me I cant find it now...
