Getting the Most Out of Visual Basic for Applications

As a developer, your goal is to write code that's fast, efficient, easy to read and maintain, and if possible, reusable. To do so, you must have a solid working knowledge of Microsoft® Visual Basic® for Applications (VBA) — what features the language includes and what you can do with it.

As you develop applications, you'll find that there are a number of operations that you must perform repeatedly — parsing a file path, for example, or returning all the files in a directory. Rather than rewriting these routines every time you require them, you can begin building an arsenal of procedures that solve common problems. This section gives you a head start by providing functions that perform some often-required operations on strings, numbers, dates and times, files, and arrays. It also explains the key aspects of each procedure and covers fundamental VBA programming issues so that you can continue to expand your code arsenal yourself. You can use these procedures not only in VBA code but also in Visual Basic Scripting Edition (VBScript) code in HTML documents.
