problem using one connection string per application

Question

Hi everybody, I'm little confused with how to get the best solution to the problem below: I built a window forms application using dataAdapter's wizard in several forms. each of the dataAdapters brought an sqlConnection with it's own connection string, so each form (class) has it's own connection, all to the same datasource ! However, when I want to change the datasource I need to follow each of the connections and change it seperatly. It does not make sense - I want to change it just once, since they all have the same datasource. a clue ? moreno
