Access Developer Level 8
Versions: This class was recorded with Microsoft Access 2016. The material is valid for Access 2007 up to 2021. Access has not changed that much over the years.
Pre-Requisites: Access Developer Level 7 strongly recommended, as you should watch all of my classes in order. However, if you're skipping around, you should have at least completed the Beginner series and the first 3 or 4 levels of the Expert series where I start to cover functions.
Running Time: 1 Hour, 20 Minutes
Cost: $41.99

This class continues our look at programming in Visual Basic for Applications in Microsoft Access (VBA, or Access VB). We will continue working with adding partial payments to invoices that we started on in Developer 7. We will begin by defaulting the amount of the next payment to the current amount due on the invoice. We'll see how to use the combo box DropDown method to automatically open the payment type combo box. We will refresh the total payments and amount due shown on the payments form and the order form after a payment is entered to avoid confusion. We'll learn about the On Unload event. We will check for overpayments and decide what to do in that case.

Next we will check to see if an invoice is PAID. If so, we will not allow additions, deletions, or edits unless a manager password is entered. We will learn how to create Public Global Functions so that we can use our IsManager function from anywhere in the database. We will see how to return a value from a function, and how to globally search and replace in our VBA code throughout the entire database project.

In the last lesson, we will take a break from the payments system and design something that I get lots of emails asking for: a Search As You Type feature. We will make a list box with all of our customers in it, and a text box that we can type a search criteria in. As we type each letter into the text box, the list of customers will automatically filter with each keystroke. In addition, we can search based on first name, last name, or company name. I cover this feature in more depth in my Search Seminar, but this is a simplified version that shows the basics of how to build something like this.
