Lotus Notes Automation: Notes.NotesSession doesn't implement Domino::ISession?

Question

I'm trying to improve my Lotus Notes client code:

Working:

#import "...\IBM\Lotus\Notes\notes32.tlb" no_dual_interfaces raw_native_types

CComPtr<IDispatch> session_dispatch;
if(FAILED(session_dispatch.CoCreateInstance(_T("Notes.NotesSession"))))
    ...
NOTESSESSION *session = static_cast<NOTESSESSION *>(*&session_dispatch);

This gives me a valid NOTESSESSION object that is aware that it needs to go through IDispatch to actually invoke methods.

I found some example code on the net, which looks a lot saner and assumes a later Notes version:

#import "...\IBM\Lotus\Notes\domobj.tlb" raw_interfaces_only raw_native_types

CComPtr<Domino::ISession> notes;
if(FAILED(notes.CoCreateInstance(_T("Notes.NotesSession"))))
    ...

However that returns E_NOINTERFACE. As others claim to have similar code working, I wonder what may be going on here, and humbly ask whether anyone else has working code to instantiate a Session object and get a working interface pointer.

Answer 1

With domobj.tlb, you should use "Domino.NotesSession" rather than "Notes.NotesSession".
