The Application Object
Introducing the Application Object . . . . 108
Visual Basic for Applications (VBA) uses objects to control Microsoft Excel. Whether you are
working with the Excel application ( Application object), workbooks ( Workbook object), or
individual cells ( Cell object), you do everything by manipulating an object. All of the objects
either contain other objects or are part of a larger object. For example, the Workbook object
contains Worksheets objects, which in turn contain Cell objects.
When working with an object, either a property is being set or read, or the object is told
to perform an action, called a method. If you wanted to select a worksheet named
Sheet2 in the active workbook, you would use the Select method of the Worksheet object,
Worksheets(“Sheet2”).Select .
The object model (shown in Figure 6-1) is used to describe how each object within Excel
relates to other objects. When you view the object model, you can see how one object contains
other objects, which contain other objects, which can contain even more objects. An object
might even contain multiple objects of the same type. For example, a workbook can contain
multiple worksheets.

in Excel.
