>>>>Thank you, Sergey. The only thing I have to watch with your approach is to set .oProp to .NULL. in the form unload, in order to avoid dangling references. With form properties and arrays, nothing has to be done when the form is closed. But your approach is interesting.

In your original suggestion should it be
Thisform.AddProperty("oProp", NULL)

instead of
Thisform.AddProperty("oProp", "Empty")

or it doesn't really matter?
