Ok I am pretty new In the OLE business, so any info is welcome.

I am using Arena, wich is a simulation tool, and I am trying to make some
sort of a front-end in Delphi 3.
My goal is that the user can select a couple of things in the D3 Front-
end and the front end builds the model in Arena.

It's possible to communicatie with Arena using OLE and I managed to start
Arena and put a Object "module" on screen in Arena.
But How do I know what methodes and properties are available in the
various OLE-Arena objects that can be called through OLE???

I also use the CreateOleObject and put it in a Variant Type var, is this
the correct way?  Cause you also have the OleVariant Type!

Also resources of OLE / Active X / Why, when, how, are welcome. Like what
is Automation OLE, why is the OleContainer???

So if anyone knows an answer to any of my questions, please dont hasitate
to answer.

Thanks,
Ido de Lepper
