Is there a way using .Net to determine which applications are currently
running?  For example, in Windows, if you press Alt-Tab, you will see a list
of applications currently running.  I have looked at process.getprocesses,
but that returns all running processes instead of just applications.  I would
like to fill a listbox with a list of applications (not processes) that are
currently running.  Thanks.

I'm not sure what yoru definition of "application" is, but I believe
the Alt-Tab window is populated with top-level windows returned by the
EnumWindows Win32 API.

Thank you for pointing me in the right direction.  I have been searching the
Internet for sample code that uses VB .Net 2005 and the EnumWindows Win32
API.  If anyone has any code that shows this, I would appreciate it.  Thanks.

Unfortunately the signature it has for EnumWindows is incorrect. The
second parameter should be an IntPtr.
