Hi Bela, NullEvents fires only when nothing happens. This means that the UDF fires only if the user doesn't touch the KB or the mouse. Right? What happens if the user runs an SQL and keep moving his mouse? I think u have to update the Thermometer during the normal events as well as the NullEvents. (It'll be slower!) BTW, How do you know in advance when the SQL is gonna complete? HTH, Biju > > > Hi everybody! > > I am working on a timer solution.
