detect changes in database

[Frank]

I have an application that is used by multiple people. They all see the same
table contents from a sql-db. If a user adds/changes or removes a record the
other users must refresh there dataset manually to see the changes. How can I
make my application aware of db-changes automaticly so that the users don't
have to manually refresh the screen.

Thanks,
Frank

The most easiest way should be a timer. Use the OnTick event to read
from the database. Now you can just refrech automaticaly your form by
calling the function or sub that you use, to update manually.

Hello Frank

if you use SQL 2000 or 2005 you can use notfication services to acomplish
this ( great new feature ) for sql 2000 this is a ( free ) adon you need
to install to get this working SQL 2005 has this functionality standard
onboard ... the database performs then a callback to your app when the
subscribed dataset changes

search on MSDN for notification services
