inhouse application that tracks my time working on various projects.
In my case the duration takes into account possible breaks in an
otherwise contiguous work period (always getting phone calls etc while
I am trying to work), and so it cannot be conveniently calculated at
the client as it must scan other records in the same time peroid.
However because it is inhouse I am quite content for the update to
happen when I hit the commit button - I dont need it to happen quite
IMO the best solution for something of this dynamic nature would be to
use non-data-aware controls and a TIB_Cursor or similar in the
background (so you can take more explicit control over the timing).
However if you can it working the way you want so much the better.
