Object Oriented Programming & Objects

Object Oriented Programming:-
VBA is a structured programming language where sentences (called statements) are constructed of building blocks such as objects, methods, and properties. These VBA statements are grouped in larger blocks called procedures. A procedure is a set of VBA statements that performs a specific task or calculates a specific result. The first step to learning how to create procedures is to learn about the building blocks.

Objects:-
VBA is an object-oriented programming language, which means the statements you create in VBA act on specific objects rather than begin general commands. Excel is made of objects that you can manipulate through the VBA statements. The entire workbook file is an object, an individual sheet is an object, a range within a sheet can be an object, and an individual cell is an object. There are many more types of objects, and as you see objects can be containers for (called collections) other objects.
