So, I have now in svn implemented the following:
- Fixed the IClassFactory::CreateInstance method
- Implemented a Pythonic interface for it, also including
the nice 'dynamic=False' parameter.
This is (almost) what I was looking for. Thanks! However, there is one
issue. Currently, CreateInstance always tries to return the best
interface, even if the interface was explicitly specified. In my case, I
want a specific interface, but due to the fact that the typelib is not
registered on the system, comtypes ends up returning a dispatch, which
is not what I want. I've attached a patch against svn trunk to fix this.
Thanks.
