Fundamental Question on DragDrop

P: n/a
Well, it seems fundamental to me anyway. Hopefully it is simple
enough.

The question is for when the source for the dragdrop is a different
application that the target for the dragdrop. How does the source for
the dragdrop operation know that a drop has been completed onto a
valid target? And then, how does the source know what the drop target
is?

I've got dragdrop working within my application but I can't see any
mechanism for handling a target that is in another application.
Specifically, I've got a Windows client app where each row in a
datagrid represents a file on a unix server. When files/rows are
dragged from the datagrid and dropped onto a directory in Windows
Explorer, the app will ftp the files to that directory. How does the
app know that the dragdrop completed and what the target is?

Thanks Much,
Gene H.
