Hi CoolBlue

Yes that's exactly the problem. I did try the same way as you showed, and in case of your last example it can be done, because it's simple and you can calculate the required bytes. But usually it's unpredictable the requirement of an object to copy, and therefore it won't work, - that way.

Now I gave some more thoughts to the function ObjectFromPointer(). That's because, what do I gain by copying the contents assigned to a pointer? Sure if still pointing to the same object (as in the example with objRange) I can ask if "Nothing" or use a property of the initial object to identify it. But in case the pointer is already assigned something else it will give me a hard time to keep the macro out of trouble.
Therefore I wonder if it would make sense to read always a fix parameter of length for example 32 and just compare the results. If they show a difference, it will tell that something else got assigned to the pointer, and that's good enough.

Just to avoid missunderstanding: I didn't say, that the reference count doesn't work at all. It's just as Bob put it "there might be circumstances when it doesn't".
In the moment we do with simple structures because it's about figuring out a way to keep track on ongoing things within memory. Therefore I'm expecting reference count doing allright and would be dissapointed if failing (though creating a new instance of an object was said in former times might be already to much for automatic deallocation, the same as for not handled errors).
