last year i started a diskussion about this http://vcampus.osisoft.com/discussion_hall/Generic_Forums/f/20/p/2706/14764.aspx#14764
The vcampus Members suggested some Vba Solution .... I would also appreciate if some Easy to use controls would exist....
I would say that an enhanced bar would be "easier" for OSIsoft to implement in Coresight than in ProcessBook.
Even with an off the shelf activex enhanced bar control for ProcessBook you are likely still going to need some VBA to feed data to the control on the display.
