The View in the Form must be found somehow - I have published two methods.
I generally prefer the second method I published tonight, but the previous one
is adequate and efficient for some circumstances - such as the case for the
'Palette Editor' example I started this long correspondence with.

Maybe there are better general methods.

Antony does scan for the View, but by using Views.Omnicast rather than
using his own code. This has three disadvantages:

1 - The Docu (see above) seems to imply that it is not a good technique.
2 - It is slow because is scans for every View in the entire system, not just
the first in your Form. It then sends every View a message which has to be handled.
3 - If there is more than one View of your type it fails to select only the
appropriate one, but updates all whether they are in your Form or not.

Cheers

Robert
