VB and C++ clients declaring the same ActiveX .dll

 VB and C++ clients declaring the same ActiveX .dll

Hi, I am writing a COM ActiveX.dll using VB 5 enterprise. The .dll will
be used by VB clients and C++ clients.  This .dll will have functions in
it to connect to a database and retrieve data.  The data will consists
of name, address, state,
and zipcode, so it can be either a single record or a list of records
with these fields that get returned from the database.  I need to pass
this data along to VB clients and C++ clients.  For VB clients I can
pass them an n-dim array or a collection of objects(collection of
classes).  But what about C++ clients?

1. How would I pass this data to a C++ client, so they can extract out
the different fields of the data?

2. What do I need to do when creating this VB .dll in order for it to
pass data correctly to C++ clients?

3. What datatype or object type do I need return back for C++ clients
that will hold this knid of data?
