Yes. VB likes to see OLE Automation (implementing IDispatch) interfaces, which has restrictions on
which data types can be used.

But in VB I cannot see them, I see only the coclass...why?

I'm not sure what you mean by "see". Does the code you show compile and
run? If not, what's the error message? If yes, what exactly seems to be
the problem?

Hi Igor, you're right I didn't explain very well...
by "sse" I mean in the Objects Viewer (F2) and the code above doesn't
work because IATDevice and ITetra are not defined!

Maybe I have to derive them from IDispatch instead of IUnknown and
using COM_INTERFACE_ENTRY2(IDispatch, ITetraDisp)?

Thanks
Daniele.
