Music Player - Playlist - Split The Filelocation From The Filename In The Listbox?

I got some music player from the web, a cool one, and i tried to add him a playlist. i`ve change the entier interface.

I have like this
- play botton
- pause botton
- stop button
- TrackBar for song
- timer for song lenght
- a volume
- a button for PLAYLIST.

This code is for Play:

Private Sub PlaySong()
If (PlayerControl.URL <> "") Then
PlayerControl.Ctlcontrols.play()

[CODE]...

It's actualy a shortcut for the button event. It checks if Url isn't empty, and if it isn't, start playing the song from that url. This is the code of the play button:

Private Sub ToolStripButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ToolStripButton1.Click
PlaySong()
End Sub

Now i`m gonna talk about the Playlist button. When you enter the exe, the playlist is Visible, when you press the button it's hidden and so on.(it's made with if then condition).

The playlist it's actualy a ListBox called lplst and has some buttons:
- Add
- Delete
- Save
- Load
- Clear

I`m gonna talk about the Add button. This button pops up a dialog box to open mp3 files to that FIleBox. And it get's ONLY the FILENAME! (without the URL or Location of it) This is the code for the Add button:

Private Sub ToolStripButton7_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ToolStripButton7.Click
Dim openfile As New OpenFileDialog

[CODE]...

Before , the Add button was adding JUST the location (example: C:\blabla.mp3) and when i selected it and click play, it was playing the song. But now i wanted to show only the file name. I got some code on the listbox change too.

Private Sub lplst_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lplst.SelectedIndexChanged
PlayerControl.URL = lplst.SelectedItem
End Sub

This code changes the URL that plays. Depends what is the selecteditem. i browsed all the web , and i couldn't find anything.

Now the problem: I can change the Add button like this:

Private Sub ToolStripButton7_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ToolStripButton7.Click
Dim openfile As New OpenFileDialog

[CODE]...

And this will link me like this: Filename - Filelocation.

But now the PlayerControl.URL = lplst.SelectedItem. code won't run the mp3 file from that location. How do i have to split the Filelocation from the Filename in the listbox?
