You have one base class virtual function how will call that function from derived class?

class a
{
public virtual int m()
{
return 1;
}
}
class b:a
{
public int j()
{
return m();
}
}


Class a
Public Overridable Function m() As Integer
Return 1
End Function
End Class
Class b
Inherits a
Public Function j() As Integer
Return m()
End Function
End Class
