Fabio,

Verify what?

I gave you an explanation that I guess you just aren't satisfied with (no real suprise there *L*).

The bottom line is that VFP is never going to let you destroy the contained internals that are defined at the class level.

The solution is simple, if you want to dynamically destroy things, dynamically create them, then you are free to do as you please.
