Courses - Microsoft Access 324
 Description: Advanced Access Recordsets Running Time: 84 minutes Pre-Requisites: Access 323 very strongly recommended Previous Lesson: Access 323 Next Lesson: Access 325 Main Topics: Loan Calculator, Amortization, PMT, Me.Filter, On Not In List Event, NewData Versions: This course is valid for Access 2000 through 2003. If you are using Access 2007 or 2010, you will still benefit from this course. You will find that the concepts are the same, but there are cosmetic differences between the versions.

NOTE: This class just covers the basics and calculates monthly payments. If you're looking to generate a complete amortization schedule (with principal, interest, start & end period balances, and the works) be sure to see my MICROSOFT ACCESS LOAN AMORTIZATION SEMINAR.

We'll begin by building a loan calculator where you can enter in the price of the loan, the down payment, interest rate, and number of years. Access will then be able to tell you what your monthly payments will be. We'll first see how this works in Excel.

Then we'll build an Access form to calculate the same basic results.

We'll make a "Create Payments" button which will use a Recordset to fill a subform with all of the payments we'll have to make over the life of this loan, including payment amount and due date.

We'll use a form footer total to be able to see the current and total balance of the loan.

Next we'll move to a very popular topic that lots of students ask me about: how to add an item to a combo box. To do that, we have to learn how to program for the Not In List event. We'll start with a simple list of customers with states.

We also need a simple State table.

We'll make a Customer form with a combo box to pick the state.

If the user types in a state that we didn't have in the State table, we'll give him the option to ADD it to the table and save it in the customer record.

It looks easy here, but there's actually a LOT of programming behind that one little Yes/No option. You'll see how to do it in class.
