Hello,

'VBA supports Polymorphism and Encapsulation but not inheritance'. But how? Can someone help me to understand.

Polymorphism : To implement polymorphism, class should implement methods or properties of other class (super class) but VBA does not support Inheritance. So how it is possible.

Encapsulation : We can declare variables as Private and to access those we can use get and set property. Is this Encapsulation?

Inheritance : We can use the variables or properties of class in Normal module, so the module is extending the class, isn't it?

Thanks.
 

Excel Facts

Which lookup functions find a value equal or greater than the lookup value?
MATCH uses -1 to find larger value (lookup table must be sorted ZA). XLOOKUP uses 1 to find values greater and does not need to be sorted.
Google'd the subject? You'll find a wealth of information.

Here's a start...https://www.google.com/search?newwindow=1&q=vba+polymorphism
