I then added the interface to my objects com map;

COM_INTERFACE_ENTRY(IPersistRegistry)
END_COM_MAP()

And finally the implementation template class to my object;

class ATL_NO_VTABLE CSomeObject:
...
...
public IPersistRegistryImpl<CSomeObject>

Now when I compile I get the following displayed

error C2078: too many initializers
error C2440: 'initializing' : cannot convert from
'ATL::_ATL_CREATORARGFUNC (__stdcall *)' to 'DWORD_PTR'
error C2440: 'static_cast' : cannot convert from
'CSomeObject::_ComMapClass *' to 'IPersistRegistry *'

The error message suggests that IPersistRegistryImpl, and hence
CSomeObject, does not in fact derive from IPersistRegistry.

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
