In this lesson we show you how to setup and use the VB Case Statement as well as how to set up and use Combo Box Drop Down Lists.
In a variety of situations the "Case Statement" programming structure is much simpler and cleaner to use than a set of nested If...Else statements.
The Step by Step Guide which is available below for this lesson shows exactly what needs to be done.
Note that the example Lesson Images shown on this web page are basic Printscreens, whereas the actual original Images are of perfect clarity and quality in the downloadable PDF Guide for this lesson.

Watch the following YouTube Video Tutorial about Case Statements.
We recommend you use the RESOURCE MATERIALS available below

The YouTube Video is free to watch as many times as you want, and the Lesson Summary Guide, with full program code listing(s) are available at a small cost which can be paid for and downloaded using PayPal.
Before purchasing and downloading the following resources, check first with your Teacher or Instructor, as they may already have copies of these documents to give to you.
Our Programming Learning Modules are designed for complete beginners, and they have been extensively trialled with High School students learning Programming for the first time. They have a proven track record of being able to get everyone up and running with Microsoft Visual Basic - the world's most popular Beginner Programmer's language.
We highly recommend using the Step by Step Summary Guide as well as the other support materials to maximise learning outcomes.
Our students have found the Summary Guide to be far more useful than re-watching the Video, when it comes time for them to apply their newly acquired skills to Application Build tasks.

The Edge purchase will work okay, but it is probably best to do Pay Pal purchases using Google Chrome as your browser.
