media player cannot play next song in listbox

Question

If AxWindowsMediaPlayer1.playState = WMPLib.WMPPlayState.wmppsMediaEnded Then

 ListBox1.SelectedIndex += 1

 AxWindowsMediaPlayer1.URL = ListBox1.SelectedItem

 AxWindowsMediaPlayer1.Ctlcontrols.play()
End If

It changes the index of the listbox, but it doesn't play the next file. The file exist and there's no problem playing it the normal way. Does anybody know what's wrong?

probably has to do with the `playState` test. The playstate goes thru many states when starting or stopping a media file. Where is that code located? — Ňɏssa Pøngjǣrdenlarp, Mar 16 '15 at 17:46

Solution is must to add timer"

Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As EventArgs) Handles Timer1.Tick
  Dim item As Integer
  item = ListBox1.SelectedIndex
  If Form1.AxWindowsMediaPlayer1.playState = WMPPlayState.wmppsStopped Then
    Me.ListBox1.SelectedIndex = item + 1
    Form1.AxWindowsMediaPlayer1.URL = FileUrls(ListBox1.SelectedIndex)
    Timer1.Start()
  Else
    Timer1.Start()
  End If
end sub

also the following code work . first add timer to playlist and past following code

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

    If Form1.AxWindowsMediaPlayer1.playState = WMPPlayState.wmppsStopped Then



        If ListBox1.SelectedIndex < ListBox1.Items.Count - 1 Then
            ListBox1.SelectedIndex = ListBox1.SelectedIndex + 1

               form1.axwindowmediaplayer1.url=listbox1.selectedindex
        Else
           'do nothing if no item to play 
        End If
    End If


End Sub

Why would you have to start a timer in a tick event? It's already running, no? — LarsTech, Feb 09 '17 at 18:45
