Yes, exactly. In my case the missing piece is to only examine GetFldState 2 or 4. Thus I said I'm taking this piece as a basis for a new method which I want to invoke as a developer's tool. I'm just not exactly sure, how would I invoke this on Demand. The method that checks for changes is in the base VPM class and I want to fire the method I need only in particular instance for debugging purposes (I'm getting "Information saved" message when I'm only viewing the info).
