    What are Disconnected Recordsets? Advantages?
    The ADO has the ability to work offline with recordsets.
    The ADO Maintains the informations such as Database name,Server in which the database reside,username and password etc…After loacting a recordset it disconnects and work with them and finally send it back to the database by re-establishing the connection by making use of the already stored informations about the connetion and the database.
    Advantage: Minimizes the Load on the SErver

    Hi,
    I was wondering if you could help me. I am developing a form in vb
    which has a MS Access db running behind it. On the from, I have a
    data grid which retrieves the information of customers (name, payment …..)
    From that db and outputs it to the screen.
    My problem is that I need to create a button on which I click
    And should give me the sum of payments (on a label) of all customers and another
    button for the sum of payments for each customer (on a label). I am sure that I have to use SQL but how to do it please.
    By the way I did the DB Access connection not in code , I did it manually in the properties of the adodc.
    Thank you very much.
