VBA (Visual Basics of Applications) is an object oriented programming language that come from its parent language: VB (Visual Basics). In other words we can say that VB Language is extended to application level.
VBA is associated with the entire MS Office applications such as Word, Excel, Powerpoint, Access and outlook etc. So you can automate MS Office applications using VBA code.
VBA is also and event driven language. That means to say that nothing happens automatically unless it is instructed to happen.
In practical sense, OOP – Object oriented programming refers to live objects such as a chart, textbox, cell, sheet etc.
So why are we talking about objects now? The reason is that you will be coding for the objects in Excel.
There are only 2 things we will be doing in Excel:
1) Performing an action on or with the object.
2) Changing the properties of an object.
1) Performing an action can be referred to actions such as inserting, deleting and renaming worksheets. Inserting and deleting rows and columns etc.
2) Properties refer to object’s parameters or attributes such as size, height, width, color etc
So there are 2 entities associated with an object namely: Object Method &
Object Property
Refer the Excel VBA Reference: https://docs.microsoft.com/en-us/office/vba/api/overview/excel
Object Method refers to the actions that can be carried out on objects.
Object Properties refers to the attribute of an object.
It is said that there are around 200 objects and 5000 methods & properties in Excel.
Excel objects are arranged in a hierarchical pattern for programmatic convenience.
