In this article, I will explain you about
Inheritance with Forms in Visual Basic .NET.
In Visual Basic .NET when we want to inherit a
class from existing class we use Inheritance. Same as we inherit a class from
existing class we can inherit a form from existing form. I show you how we can
inherit a new form from an existing form. Suppose we have a Form1 with
some controls and we want to derive those controls in a new form from that
Form1. For this select Project->Add New Items from the main menu.
By this you open the Add New Item Window.
In this window select Windows Forms then select Inherited Form and
click on Add button to add inherited form in your Application.
When you click on add button Inheritance Picker Window will be opened. It looks like the image below:
Select Form1 in the
picker and click OK. When you click OK new form, Form2
which is derived from Form1 is opened. Everything on Form2 is same
as Form1 even the name is also same. The only difference between Form1
and Form2 is that every control on Form2 have the icon. That
indicates that the form is inherited from other form and the derived controls
are locked. It looks like the image below:

I hope this article help you
to understand about Inheritance with Forms in Visual Basic .NET.
