I would like to know the VBA basics (to Write Macro's) and also looking for few examples which is easy to understand to Macro's.

Using what application? VBA is different for each application that supports it. That is because VBA is a superset of the Visual Basic language containing extensions that are used to manipulate the objects particular to the application.

In some apps macros and VBA are the same, in others they aren't. So you need to be more specific about what you are using. You also need to be more specific about what you want to use VBA for. We can recommend ways to learn, but we can't tell you how to do things in general, that is beyond the scope of this medium.
