That is how the do ActiveX, and how Delphi does multi-tier support with
MIDAS (using DCOM).
That is exactly why I think the *language-concept* (here a thingy
that provides reference counting, auto-creation and auto-deletion of
an instance etc of a classes instance) should be described
independently of COM, DCOM, Axtive X, MIDAS and such things that are
not related to the language itself, while the language concept/syntax
- being useful in itself, anyway, can *additionally* be used to allow
the programmer to handle COM, DCOM, Axtive X, MIDAS and such things.
It's also interesting to be able to state unambiguously whether the
use of interfaces in a program pulls in any external libraries or
attempts any external communication.
The use of interfaces themselves does not pull in any external libaries.
They are merely implemented in a way to simplyfy the use of certain
libraries.
Thanks for that clarification :-)
