Access Developer 16
Access Developer 16 covers Multi-Select List Boxes and Recordsets.
Developer 16 spends more time on List Boxes, specifically unbound list boxes (not bound to a table or query). You will learn how to manually add, delete, and edit items in the list. We'll see how to add colors and formatting to a list box - well, not really, but you'll learn a cool workaround. We will start learning Recordsets which are a very powerful tool for directly editing data in your tables in VBA code.
In Lesson 1, we will review the homework from Developer 15. We will see how to create select all and deselect all links below each of the list boxes with only one subroutine handling all four cases. We will create a status message saying "3 customers marked valid" or whatever the count may be. Finally, we'll use an IIF function to display "1 customer" or "2 customers."
In Lesson 2, we will fix a bug that crept into our list box form, and we'll see how to fix a visible glitch in the way Access displays list box values sometimes.
In Lesson 3, we will answer the question that I get asked all the time: "is it possible to put colors and formatting in list boxes?" I'm not going to ruin the surprise, but, take a look at the picture below. I will show you how to create something that looks very much like a colorized, formatted list box.
In Lesson 4, we are going to learn about a very powerful way to work with data directly in our tables using Recordsets. These are objects that we can use to read, write, add, delete, and manipulate data directly in VBA code without having to use SQL, which can be slow. We'll talk about what Recordsets are, why we want to use them, and we'll set up our first example.
In Lesson 5, we will learn how to loop through the records in a recordset, displaying whatever fields we want. We will then add those items from the recordset to an unbound "value list" list box. We'll also see how to manually add and delete records from the list box.
