I created a container class, with all PEM'S hidden except for
Top, Left, Name and a couple of user defined PEM's.

I dropped it onto a form, and in the Click of a button I typed:

ThisForm.cntMyContainer.

and at this point IntelliSense opened showing ALL PEM's, hidden
or not.

If I double click the container on the form, I only see the methods
that were not hidden, and the property sheet only shows non-hidden
PEM's.
