Determining Source of Drag Operation (Control or App)

My question is fairly straight forward. I'm using .NET framework 1.5. I
want to do the following:
(1) Select a portion of an HTML document in an IE browser (either internally
hosted or an external app)
(2) When I drag that selection (possibly including images) onto my WinForm
(assume a hosted browser control) I want to be able to determine the URL from
the drag source. This implies being able to determine which browser instance
it came from and then drilling down to the current document URL.
(3) I would also like to be able to do the same sort of thing if the drag
source is an MS office document.
The question is can I determine the source of a drag operation? By source,
I mean any one of the following - external app (like a browser or ms word
doc), a hosted app (like ms word being hosted within my winform), or a
specific control within my app?

Thanks for any help,
