Your goal is unclear. Inheriting buttons makes sense, but inheriting "any window forms" does not. What do you mean by inherit "any window forms"?

For inheriting buttons, it's quite simple:  add the pertinent buttons to the base form. When you inherit this base form, all the of the buttons you added to the base form should be accessible in the child form.

look my first question.

I have written my own class  "BasicFunctions.vb".  
I have created my own class named mybutton.vb.  it  inherits button. look my first question.
I have created my own class named myform.vb.  it inherits form. look my first question.  

BasicFunctions class should be inherited to myform.
BasicFunctions class should be inherited to mybutton.
how to achieve it ?

I want to inherit  this class  any of my custom input controls like(MyTextBox, MyComboBox,etc)

public class mytextbox
inherits textbox
end class

public class MyComboBox
inherits ComboBox
end class
