Broadly speaking, Microsoft Visual Basic can be considered the sum of the Visual Basic for Applications library, plus a group of objects exposed by the Visual Basic library and the Visual Basic runtime. In this chapter, I focus on the VBA language, with an overview of its functions and commands, and some advanced or less obvious techniques that you can apply to it. You can browse most of the objects covered in this chapter by using the Object Browser utility and selecting the VBA library. In the last part of the chapter, I introduce a few important system objects, such as App and Clipboard, which are located in the VB library.
