Hi,

I'm learning C++/COM/DCOM at the moment and I don't know how to create
"nested classes" in my C++/COM server.  For example, I want to create
a COM server dll that can be used in a client tool (eg VB6) that can
do the following (the example is taken from Finance but could equally
be taken from any other field):

Dim oCallOption as InstrumentLib.Option.Call
Dim oPutOption as InstrumentLib.Option.Put

Set oCallOption = new InstrumentLib.Option.Call
Set oPutOption = new InstrumentLib.Option.Put


What do I do in C++/COM to create the "nested objects" Option.Call and
Option.Put?  How do I expose Properties/Methods on a COM object that
are Custom data types and not intrinsic data types?

Thanks
Mark
