VBA uses objects to control Excel behavior so if you want to master this programming language and make the most of it you need to get acquainted with objects and collections, as well as with their properties and methods. In this text, I will introduce you to the most frequently used Excel objects: Application, Workbooks, Worksheets, Cells … In some of the following articles, we will deal more closely with each of them.
Excel has a large number of objects, and the VBA allows us to easily create and manipulate them. We can declare variable as an object by specifying the variable name and the object name as a type. Then, using the Set command, we assign the actual object to a variable. Once this is done, we can change its properties or run methods – subroutines that allow further manipulation of objects.
When we declare a variable as an object or custom data type we can access its members in many ways. In the opinion of many, the easier way is to individually “frame” the object fields by the With structure. Instead of dividing the variable and field name by the „points“, it allows us to define a block of commands, enter values by specifying field names, and then closing a block that completes the value assignment process.
