>>VFP 9 help says "Returns the current value for a property or program code for an event or method at design time" and says the return value is "Character, Currency, Date, DateTime, Numeric, or Logical." So it's not obvious - and, technically, not documented - that you can get an object reference. And, for instance, a container is not a property of a form, it would be an object placed on a form and a property of the container would be something like cnt.Width.

Taste should never be as important as engineering. :)
