I am completely puzzeled on what exactly is happening. Here is the codes that I think have to be doing it some how so you don't have to typed them out from the video or anything.

Form Load:

Try
            TextBox2.Text = My.Settings.Friends
            TextBox2.Text.TrimEnd()
            Dim NewArray() As String = TextBox2.Text.Split(vbNewLine)
                For Each item As String In NewArray
                    If String.IsNullOrEmpty(item) Or String.IsNullOrWhiteSpace(item) Then
                    Else
                        ListBox1.Items.Add(item)
                    End If
                Next

        Catch ex As Exception
            MsgBox.Show()
            MsgBox.Label2.Text = MsgBox.Label2.Text + "E013 "
        End Try

Form Closing:

TextBox2.Text = ""
        For Each thing As Object In ListBox1.Items
            TextBox2.AppendText(thing.ToString & vbNewLine)
        Next
        TextBox2.Text.TrimEnd()
        My.Settings.Friends = TextBox2.Text

Selected Index Changed:

Try
            PictureBox2.ImageLocation = "http://avatar.xboxlive.com/avatar/" + ListBox1.SelectedItem + "/avatarpic-l.png"
            LinkLabel1.Text = ListBox1.SelectedItem
        Catch ex As Exception

        End Try
