You raise a good point, Bob,
I gave a presentation in my last class on objects and classes
(it was an addition to the normal material in the text), and
I think the students got it by relating to the VB environment.
It helped a lot to point to an object on a form, point to its
properties (attributes), and change an attribute (watching the
object change in the process in some cases).
It is a key to not get lost in the language as opposed to the
The "Objects and Classes" presentation is on my website as well.
