Like so many others, the only way is QueryInterface for all possible interfaces. And this is exactly what the Microsoft OleView tool does for you.

In no case. The idea of ​​COM interfaces is that you request an object - "please give me the XYZ interface if you support it), and the object decides how to respond - provide a link to yourself or set the interface of some internal object, etc. .t knows which interfaces the object "supports" without asking for the object as described above. This was a constructive decision by COM designers.
