How do I pass a variable as a parameter?

I am a newbie in Visual Basic and I got stuck while trying to program a Tic Tac Toe game. I was trying to pass a variable as a parameter for a subroutine but I have no idea how. Here is my code. 

    Private Sub btn1_Click(sender As Object, e As EventArgs) Handles btn1.Click
        ButtonDisable(btn1)

    End Sub
    Public Sub ButtonDisable(ByVal ButtonSelected As Object)
        ButtonSelected.enable = False

    End Sub

In the code, I am trying to disable btn1 by running the variable as a parameter in a subroutine. Every time I debug the program, Visual basic tells me "Public member 'enable' on type 'Button' not found."

The problem is that your parameter is of the type Object, so inside the subroutine you can only use the members that are known to exist for Object instances. Change the type to Button, or the base class Control, to access the members that are specific to buttons, or controls.

Public Sub ButtonDisable(ByVal ButtonSelected As Button)
  ButtonSelected.Enabled = False
End Sub
