A new problem

Thank You Sir,

You can simply call display() here as it's a public method which the Book class inherits from Pub.

You only need to use MyBase to call the base class constructor or to call base class members which are hidden by similarly named members in the derived class.

There are some other problems I noticed in the program:

1. Sub Main() should be declared as 'Shared' to be a suitable entrypoint to the program.

2. In Sub display(), the Console.WriteLine() should use '&' rather than '+' to concatenate the strings.

3. In Class Book, Inherits Pub should be on a separate line.

Class Pub
    Public price As Single
    Public title As String
    Public Sub New(ByVal p As Single, ByVal t As String)
        price = p
        title = t
    End Sub
    Public Sub display()
        Console.WriteLine(price & " " & title)
    End Sub
   
End Class

Class Book
    Inherits Pub

    Public page As Integer
    Public Sub New(ByVal p As Single, ByVal t As String, ByVal p1 As Integer)
        MyBase.New(p, t)
        page = p1
    End Sub
    Public Sub Show()
        display()
        Console.WriteLine(page)

    End Sub
    Shared Sub Main()
        Dim b1 As Book = New Book(25.7, "Radheya", 51)
        b1.Show()
    End Sub
End Class
