That's rather a lot of nuances you're asking for.

DCOM is death. COM+ is nice for database transaction management or for
specific threading sync needs, and COM is alive and kicking. If you compile
a VB6 activex object, you have already simple ready to use object.

What are you exactly trying to accomplish? (because getting info on death
technology is waste of time).

Well, my new employer is still using it. I need to get up to speed
with their old code before I can help upgrade it to .NET.

So do you use C++ and DCOM or is it all VB6?

At this point I don't know what this company is using for their COM
objects. I just wanted to go through a crash-course to get up to speed
with this kind of programming.

Sorry, there is no such thing.

DCOM is a separate theme, and because DCOM was so difficult to implement
(all about marshaling and networking protocols) COM+ was made, so if you
'configure' a simple COM component, the COM runtime (that is COM+ as well)
will do it all for you.
And if you use C++ 6 up to 8, and you write ATL COM components, it's very
easy to support COM+.

Now comes the difficult part, that is doing it all without COM+ but through
DCOM.


I think you --really-- should focus on your target by getting some samples
about the current enviroment before jumping 'wildly' in all those subjects.
I know through some experience that COM+ can be very widely spread with
possible technologies and settings etc, and the same applies to DCOM.

I would just advise you to use ebay and find a second hand book about COM+
and DCOM.
