Hi expert... if i may ask help please.... my app is already working fine... i just want to add a little feature... I have a database in my server, then i have to client computers... What i what to do is from the two client will insert data into the database in the server, then from time to time the server checks whether there are data input from the two client... like every minute checks new records added, or after two minutes or five minutes... the insertion of record is already done, but i dont know to check automatically if there are records inserted... thanks in advance...
