DAO vs ADO

Is DAO connectivity still used? and when would it be advantageous to use it over an ADO connection?

RE: DAO vs ADO

James,
Sorry, just picked up your query...

My understanding is that ADO does everything that DAO does, but in a more generic way. I think you would come across DAO only in code that's quite a few years old. If you were doing a major rewrite or enhancement, it might be worth migrating to ADO, but if it ain't broke ...

Access tip:

How To Find All Overdue Accounts?

To find overdue accounts create a filter that compares today's date with the Invoice Date in the table. To do this:

1. Open the Query in Design View
2. Select the field for the filter and in the criteria row enter:

<Date()

This filter returns records where the Invoice Date is before today's date.

This filter can be manipulated if, for instance, Invoices are due 15 days after the Invoice Date. For this the filter would be:

<Date()-15

This filter returns records where the Invoice Date is 15 days before today's date.
