Web Browser with Tabs and Bookmarks Help

Hey there,

I made an advanced web browser with tabs and bookmarks. But when I try to delete my bookmarks, it will not delete it after you close the program and open it again. I made the program with Visual Basic 2010.

Please help me someone who could fix this? Below is the Bookmarks program code:

Code:

---

Public Class Bookmarks
    Dim SW As IO.StreamWriter
    Dim Favorites As String = "C:\app.favorites.dat"

    Private Sub Bookmarks_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
        Form1.Load_Favorites()
    End Sub

    Private Sub Button3_Click(sender As System.Object, e As System.EventArgs) Handles Button3.Click
        ListBox1.Items.RemoveAt(ListBox1.SelectedIndex)
    End Sub

    Private Sub Button4_Click(sender As System.Object, e As System.EventArgs) Handles Button4.Click
        ListBox1.Items.Clear()
    End Sub

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        My.Settings.Bookmarks.Add(TextBox1.Text)
        ListBox1.Items.Add(TextBox1.Text)
        SW = System.IO.File.AppendText(Favorites)
        SW.WriteLine(TextBox1.Text)
        SW.Flush()
        SW.Close()
    End Sub

    Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click
        My.Settings.Save()
    End Sub

    Private Sub Button5_Click(sender As System.Object, e As System.EventArgs) Handles Button5.Click
        End
    End Sub
End Class

If you want me to include the entire code then please tell me. If you know how to fix it, then THANK YOU!

I see no deletion from My.Settings anywhere in this code so how were you expecting any other result?
