Hi

Based on my research, we need to P/Invoke into Win32 API OpenDesktop to
determine if a desktop is running.

Here is a link about how to call OpenDesktop in C#

Steve,

In fact is VB Net not made for this. You are in an application, that is not
meant to intervent user settings.

You can bring yourself in big trouble additing this in your program, by
instance when a user has a all his passwords on screen from his accounts and
assumes that the password secured screensaver starts in 30 seconds and he
(after doing some simple things not at the screen) leaves the room for 2
hours.

Just my thought,

Cor

Hi Cor

I don't want to interfere with the screensaver, just detect when it runs to
go and do something else
