Good catch and nice follow-up, — and were right that the full path must be kept somewhere. The two-ListBox trick works, but it’s fragile and hard to maintain. A cleaner pattern is to keep one list of objects (or a bound list) where each item carries both the display text and the full path. The UI shows the friendly name while your playback code always uses the stored absolute path.

A minimal, safe pattern (VB.NET) is to store a small class for each track and bind it to the ListBox:

Public Class TrackItem
    Public Property Title As String
    Public Property FullPath As String
    Public Overrides Function ToString() As String
        Return Title
    End Function
End Class

' Build a List(Of TrackItem) and set it as the ListBox DataSource

On selection, read the stored full path and hand that to your player. Always guard against nulls and missing files before attempting playback:

Dim chosenPath As String = TryCast(listBox.SelectedItem?.FullPath, String)
If Not String.IsNullOrEmpty(chosenPath) AndAlso IO.File.Exists(chosenPath) Then
    mediaPlayer.URL = chosenPath   ' or set your player source appropriately
End If

Troubleshooting tips: verify the file actually exists (IO.File.Exists), prefer SelectedIndex synchronization if you must keep two controls (sync indices rather than copying item strings), and watch for permission/lock issues on network drives. If a player rejects local paths with spaces, try passing a file URI (New Uri(path).AbsoluteUri). For richer UIs use DisplayMember/ValueMember or a ListView with a Tag to hold the path. This keeps the UI clean and makes playback logic reliable.

x = system.io.path.getfilename(track) will only give you the filename.

If you want to display only the filename, but still have access to the full path, then I suggest that you add a second, hidden, ListBox where you store the full path and filename.
And every time that you add another track to the playlist, then at the same time add the full path to the second ListBox using the "track" string.

So, when you click the song in the playlist, the song gets played from the second ListBox.

You could also use a ArrayList to store the FullPath of a file.
.Check out this thread for some basic info on using a ArrayList.

thanks guys but I already solve the problem using two listbox the first listbox use the system.io.path.getfilename and the other one not use and in the selected listbox which use the system.io.path.getfilename when the item is selected it will also select the lsitbox2------> [code] listbox1.selecteditem = listbox2.selecteditem [\code] same idea with you oxiegen:) and also codeorder thank to the link another algorithm:)
