No, I'm sorry to say that IMO you did not. I looked at your code.

It simply works by accident in Delphi, because you are calling a method of the 
same object as the caller. Try calling a method of another object, and displaying 
the classname and make sure you trash the registers between the assignment
of the method pointer and actually calling it.
