So may happen that i change a value in the first tab (i.e : price) and in the second tab this value is used and performed a calculation.When i move between tabs i'm forced to execute "dbtable.refresh" everytime,spending so much time for the refresh and calculations. It's possible to implement a push mechanism to save updates? In other words,some mechanism that notify only the interested records that use the base data. A little example : TAB1 name,price chicken 50 salt 10 sugar 20(changed) milk 22 TAB2 name,price sweet milk 10+22=32 (interested to the change) salt chicken 60 (not interested) thanks [Edit by yeffa on Friday, December 14, 2007 @ 12:44:25]
