I have two classes in my project Parent and child.Child class inherits Parent class.I have two public data members of Parent ie a and b.I have two public members of child ie c and d.

I creates object of child and pass it to display method of Parent class and my this method will display values of c and d.I did in java but how it is possible in vb.net.

The VB equivalent of this is Me.

You might need to write a <parent>.Display method.
