Can we get object size from the Interface pointer?

How can we determine the sizeof object from the interface pointer?

No, not unless the interface in question exposes a method for it. An interface pointer is just what it says - a pointer.

Nice. Can you tell that to the guy in my thread just below? ;)

Sometimes there is no object behind the interface pointer at all, only the set of functions.
