[RESOLVED] problem with music playlist

[957]

Here is the relevant code.

    Private Sub Add_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PLAdd.Click
        OpenFileDialog2.ShowDialog()
        Playlist.Items.Add(OpenFileDialog2.FileName)
    End Sub

    Private Sub Remove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PLRemove.Click
        Playlist.Items.Remove(Playlist.SelectedItem)
    End Sub

    Private Sub PLSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PLSave.Click
        IO.Directory.CreateDirectory("C:\Selector\Playlists")
        Dim w As New IO.StreamWriter("C:\Selector\Playlists\test.txt")
        Dim i As Integer
        For i = 0 To Playlist.Items.Count - 1
            w.WriteLine(Playlist.Items.Item(i))
        Next
        w.Close()
    End Sub

    Private Sub PLLoad_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PLLoad.Click
        Dim r As New IO.StreamReader("C:\Selector\Playlists\test.txt")
        While (r.Peek() > -1)
            Playlist.Items.Add(r.ReadLine)
        End While
        r.Close()
    End Sub

    Private Sub PLPlay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PLPlay.Click
        Process.Start(Playlist.SelectedItem)
    End Sub

I want to allow the user to name their own file for the playlist instead of it being "test.txt".

I want a way to avoid duplicate song files.

I want a way to shorten the file name to exclude the file path. (I'll probably have that figured out on my own)

I want to overwrite one playlist with a loaded one.

Finally, How can I make this symbol, ►, in vb.net? (for my play button)
