<h2>If I use this code , I can only see the last line in label.<br /></h2>

<pre><code>Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim RotateCount As String()
    For i As Integer = 0 To RichTextBox1.Lines.Length - 1
        Label1.Text = RichTextBox1.Lines(i)
    Next
End Sub

<p>I mean, assume that we have lines in richtextbox like..</p>

<pre><code>a1
