Closing an open program

I'm making a program that shuts off if the computer is idle for one minute. I have an idea for this. Have a program that turns on when the computer is idle and shuts down the program I need to shut off. When the idle run program is shut off, it reloads the program.

I need to know how to shut down a program in operation.
I know how to start a program.

OR

I need to know how to detect if the computer is idle from VB

You'd have to create a system wide hook.
For some nicely done sample visit www.vbaccelerator.com and browse that site.

Good luck.

I'm having trouble finding the page I need. So if anyone is reading this thread please post an answer.

if you dont wanna do that, just find the mouse x,y, and use a timer to see how long its been idle, then shutdown

Nooooooooooooooo ... just detecting mouse position wouldn't do ... There is a keyboard, background processing, file download, file copy, etc etc etc ...

It needs to be checking system idleness, not program idleness

I found the page...and I only half get it. Can someone explain it to me

Turiya,
here is what I think and I apologize if you take it offencively: if your VB6 level of expertise is somewhat of a beginner then I'd recommend you to stay away from subclassing and hooking for awhile until you get a good understanding how it works (and not just understanding someone else's code - there is much more involved than that). Sorry.

My best regards.

Then how else would I do it?
Remember what I need to know.
How to kill a program running if I know its path and caption and everything it does.

OR

How to detect idle time.

I don't think you can kill a process you didn't create.

So there is NO WAY to close an open program?

This code will kill an .exe, but it is not that easy to understand. The bottom line is how to call it.

You really should search for answers. If you work for them, they are worth more in the long run.
