Yes, but after then, from the module itself (for some general module not
part of your product that does the hooking) how do you find out where it
came from.
Someone already said earlier in this thread (I think) that Contents
Supervision -could- save all the necessary information, but it doesn't.
And yes, some other product -could- save all the necessary information,
and create a query interface that would return it.
But the question under consideration is, in today's environment, how can
a program tell with certainty where it was loaded from. And the answer
is that it can only tell for a subset of the cases, because the system
does not save enough information to provide the answer in the rest of
the cases.
