> About addressing - I hope that internall address of call-back function inside of ActiveX object can be used by the way I described, and it will be different for different instanses of ActiveX objects in VFP. That is my main question: is it right?

This is not my area either, but I would think that you are right: functions in your control would be addressable externally. But they may not be COM methods...


> I doubt that Bela's FLL was written on Delphi. I have little of experiense in C++, so I feel not smart enough to write ActiveX in C++. My medium-level language is Delphi.

I doubt it too, especially since the LCK uses C++ code.
