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.

Adding comments

In this recipe, we will be working with comments. Before we start, you need to understand three important principles about comments:

  • VBA code does not depend on comments, meaning that macros will run flawlessly without a single comment.
  • At the same time, comments are an important and often-ignored element in code.
  • The most important reason why you need to leave comments in code is two-fold.

    Comments, or notes, serve as a reminder to yourself. You sometimes create complex sequences for a client, save the file, and move on. When you later see that macro again and need to make adjustments, you will be shocked to realize how little you remember of the thinking process you went through to create that macro.

    Comments also serve as an explanation for someone else that might have to amend your coding. Instead of trying to waste time on trying to figure out your thought process, comments make a world of difference for that person.

  • Finally, when you record a...
