I suggest declaring it outside of the method, this way you can access it from other methods:

Private _Form2 as new Form2

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

 Me._Form2.Show()
 Me.Hide()

End Sub

Try this:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim newform as New Form2
    newform.Show()
    Me.Hide()
End Sub

You can have more than one of the same form open, so you need to create an 'instance' of the form, before you tell it to show that instance.
