knowing which application has focus

[Justin Creasy]

I am creating a program to monitor the open applications on a desktop
(kinda like "Applicatio ns" tab in the Windows Task Manager). You can
access all of the information you can see in the Task Manager, but I
want to add some functionality.

The main thing I want to be able to do is know which of the
applications currently has focus in Windows. I haven't found anything
in the Process class in .NET. Can anyone think of a way to know which
application currently has focus?

Re: knowing which application has focus

Justin,

You should be able to call the GetForegroundWi ndow API function through
the P/Invoke layer to determine which window is in the foreground (and
ultimately, what has the focus).

Hope this helps.
