I know, I know ... you can see them using vlax-dump-object. I'm looking for something similar which can return a list of these so I can easily use "unknown" properties / methods of any ActiveX object (not just ACad ones).
It'll need to return the name, if it's read-only, and (in case of methods) how many arguments are needed. It must be possible since VLIDE's inspection does this as well. Not to mention the vlax-dump-object function itself.
