Hello all,

I try to write an (OCX-) DLL with the CPP-Builder. I want to use this DLL
as an OLE InProcess-Server from Delphi.

The problem is, that Delphi reports an error "class not registered" when I
try to
access the com object.

I load the (OCX-)DLL in the Delphi program and call DllRegisterServer. This
function is exported from the (OCX-)DLL. This should register all ole
objects
residing in that DLL. I don't want to register the ole objects globally with
RegServ
(and I need not if I call DllRegisterServer).

I think the main problem is, that my CPP-Builder DLL does'nt create an
interface
for the ole automation object it exports and I don't know how to create one.
Also a Typelib would be usefull (how do I create one for C).

I wrote a similar (OCX-)DLL in Delphi (3) itself, and could call the ole
object
without problems (in the way I described above).

My first question is, how are you trying to access the COM object?  Are you
doing a
Variant::CreateObject or a CreateOleObject?

Where is it registering them?  According to the docs I've read, the
DllRegisterServer is used
to register the server and it's type library in the system registry.  Why
don't you wan the objects
to be registered globally?  If you really don't want them registered, create
at least one registered
object that can then be used to access the other non registered objects.
Just make sure the
instancing type is set to internal.

C++ builder does not support interfaces like Delphi 3 does.  In Delphi 3, a
type library
is generate for you and you can specify multiple interfaces that a COM
object supports.  You
can't do this in C++ builder.
