VBA Automation for Excel 2019 Cookbook

By: Mike Van Niekerk

Overview of this book

Visual Basic for Applications (VBA) is a programming language developed by Microsoft to automate tasks in MS Office applications. This book will help you to focus on the essential aspects of your role by automating mundane tasks in Excel and other Office applications. With comprehensive coverage of VBA delivered in the form of practice problems and bite-sized recipes, this book will help you to hit the ground running. Unlike most books that assume prior programming experience, this book starts with the fundamentals and gradually progresses to solving bigger problems. You’ll start by becoming familiar with VBA so that you can start recording macros right away. With this foundation in place, you’ll advance to using the full capabilities of the language as you apply loops, functions, and custom dialog boxes to design your own automation programs. You'll also get to grips with embedded macros and other advanced tools to enhance productivity and explore topics relating to app performance and security. Throughout this VBA book, you’ll cover multiple practice projects in Excel, Word, and PowerPoint while exploring tips and best practices to hone your skills. By the end of this book, you’ll have developed the skills you need to use VBA to create your own programs that control MS Office applications.

Exploring various bugs

Before getting too excited about eliminating bugs, we need to understand what we're dealing with. Some errors are obvious, and therefore, easy to find and eliminate. The syntax and compile errors discussed in Chapter 11, Handling Errors, fall into this category, because we eliminate them before running the procedure.

What we're dealing with here is the typical runtime error, which will only rear its ugly head once we run the procedure.

This is a theoretical recipe, in the sense that we are going to identify and list various bugs. Other than making notes, either in Word or Excel, nothing else is needed.

Here is a list of the different categories of bugs:

  • Logic error bugs: The name says it all, meaning that whatever you're trying to do with your code doesn't make logical sense. A simple example would be when you assign the wrong value to a variable. All calculations related to that variable will result in incorrect results.
