Open file in application externally

[ElmoWatson]

I'm using VB.net 2005 - -
I have 2 questions, actually - - -
1. I remember, in VB6, there was a way, to set command line parameters or
something, so that, if you use the 'Open With' option, or dragged a file
onto the MDI interface, it would open inside the interface.

2. How can I make it so that, if the application is already open, trying to
do the above will not open a new instance, but open it with the currently
open instance?

Does anyone know how this all is done in VS.Net 2005?
