[2008]how to include class.vb ?

[goldenix]

I cant find the answer nor in the google nor in the help file & not even in the faq-s. So How I do this?
How can I make my msgbox in form1.vb output this sampletext declared in class1.vb ?

I added item class1.vb this is how it looks inside.

Public Class Class1
    Dim sampletext As String = sampletext = "flowers"
End Class

in my form1.vb

 Public Class Form1
  Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        MsgBox(sampletext)
    End Sub
End Class
