hi,

i am trying some multiuser case but at one case ,it's difficult for Me.
Datbase - SQL Server
From End - using SWING.

consider their are 2 form. one form A which will create new Area . & other form B will use to create new Supplier.new supplier should reuired area that is not a problem.in supplier form,area is display in COMBOBOX what i want to do is

1) at one PC ,one User open Supplier form to create new Supplier with details when he will doing this at the same time
2) at other PC (Multi User Case) - other user will open Area Form, & create New Area, Save Sucessfully,transction commit.

so Q-
when user save Area Details sucessfully - that new area should refelect to other user that new area is added.

i have try on Click on Combo/Select Index On Combo means every time combo fill with area/or gotfocus ,but if their are 1000 or More records then
every time fill that combo i think will take time.

so how this case is handle in real Life ?

thanks
