Can VB determine the desktop has changed?

Say I took a screen capture of the desktop...is there a way to monitor the system to see if a user does anything to change the desktop.

I'm certain there must be but it may be in the way of callbacks. I am just hoping there is some Magic API that somehow has an event that fires when the desktop changes(i.e. window moved, mouse moved, typing, focus, etc.)

Any help is appreciated.

You could install a WH_JOURNALRECORD system wide hook to monitor the user's actions ...unfortunately this is onerous from VB without a third party dll - see AllApi.Net for how they do this.

HTH,

Thanks MerrionComputin...I forgot about the EventVb.Dll. Although, it has the event for JOURNALRECORD it fires all the time. I truly only need to know when the desktop "Visually" changes. I may be able to make it work though if I can't find a easier solution.

Any more ideas?
