Hi
How can I quickly detect whether the data entered into the TextboxA will cause a duplicate in the database as soon as it losts focus?
I'd set the referencial integrity in the database but the referencial
integrity just take place when I'd completed all the fields and trying to
save the record. I want to have an immediate validation as well as the focus is shifted over to other controls. Should I use the Findfirst method to check duplicate on the textboxA_validate(keepfocus....) procedure ?
