how do you link variables through forms?

like i have form 1 and form 2
and i have a integer on form 1 called x
how do i get this to show up on form 2?

vb.net Code:

' Form 1 code
Friend x As Integer
 
Private Sub Button1_Click( _
    ByVal sender As System.Object, _
    ByVal e As System.EventArgs _
) Handles Button1.Click
 
    Dim frm2 As New Form2
    frm2.frm1 = Me
    frm2.ShowDialog()
    frm2.Dispose()
End Sub
 
 
' Form2 code
Friend frm1 As Form1
 
Private Sub Form2_Load( _
    ByVal sender As System.Object, _
    ByVal e As System.EventArgs _
) Handles MyBase.Load
 
    MessageBox.Show(frm1.x)
End Sub

That's the loosest possible solution short of putting everything in a module. If the second form requires just one piece of data from the first form then it's a far better idea to pass just that piece of data rather than a form reference. Passing the data to a constructor is preferable if the second form MUST have that data. Otherwise a public property of the second form should be set from the first form.
