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.

Correcting a runtime error

Runtime errors are by far the most common type of error you'll come across when working in VBA. As the name suggests, these errors only occur once you run the code. Unlike with syntax and compile errors, there is no way for VBA to check your code for actions that will happen after the procedure starts running.

To come up with a list of possible runtime errors is virtually impossible because situations and procedures are never the same.

One typical runtime error that occurs from time to time is when you create a link to an external file, and then accidentally delete that file. Only when you run the code will an error message be displayed. Another example is when you refer to a range that does not exist.

In this recipe, we will be correcting a runtime error.
