Is that other TLB registered? Check that its LIBID appears in the

Well, this might be my problem; the TLB which is produced during
compile time has no corresponding DLL. This is because it contains
only "pure interface" types with no implementation.

You can register a standalone TLB file.

Does this mean that I need to create "dummy" co-classes for those pure
interfaces, put them in a DLL, and register them on the target

No to dummy coclasses and put in a DLL. Yes to register the TLB file on
the target machine.

How do you implement IDispatch? Do you use IDispatchImpl? If so,
which LIBID do you pass as a parameter to it? Also, do you pass
correct version number?

Well, those types do not actually have coclasses (yet) ..

What do coclasses (or absence thereof) have to do with my question?

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
