Oh......thanks for the advise....
I was really looking at COM and DCOM to help increase my knowledge in these
areas.
I will STILL have a play, but only so I know I can get it working....
Thanks, Jeremy Coulter

Subject: RE: [DUG]: DCOM in Delphi
After using COM objects in D3 and Automation Objects in D2 for about 3
years I can tell you quiet categorically -
DONT USE DCOM !!!!! EVER !!!!!!
With D3/4 you have the option of using the socket server. We have found
this to be as fast (if not faster) than DCOM, it works well on 95 and NT,
there is no NT security issues to worry about and it's simple. DCOM is a
pain in the rear at the best of times. I've never managed to get server
objects to "run as" a specific user under NT successfully, so you have to
leave the server logged in as a specific user. DCOM under 95 also requires
that the server objects are running as they will not auto-launch.
The downside of using sockets is that remote objects/servers have to be
implemented as Remote Data Modules which means you are using Midas but you
don't have to use TProvider - except for data access - so I don't know if
licensing is required.
If you want a demo some time, give me a call.
