Hi,

I have two questions:
1. Is it possible to load a module at runtime and instanciate some class
from an interface from this module (Like the good old LoadLibrary() call)

2. Is it possible to implement a dual DCOM interface in a way that other
programmers can use the interfaces from VB6?

It would also be nice to get a short hint of how it can be done (no simple
'yes' or 'no's please)

Thanks
Michael

Yes, read about Reflection in the docs.

Yes, read about COM interop in the docs.

Sample code is included with the Framework SDK, in the
\Samples\Technologies\Reflection and \Samples\Technologies\Interop
directories.
