Hello,
I have a moodest mp3 player which has a playlist as listbox1 which
shows full path or each inserted file.

The problem is, when a media playing is ended, i want my listbox to
select automatically next (under/below) item to continue.

What things can i add to that code:

If Me.AxWindowsMediaPlayer1.playState =
WMPLib.WMPPlayState.wmppsMediaEnded Then


End if

Shouldn't it be:

Me.ListBox1.SelectedIndex = Me.ListBox1.SelectedIndex + 1

You might want to do an if..then test to make sure you aren't at the
end of the List however.

Thanks,

Hi Seth Rowe,
Great it worked for selection next item, but i couldn't make out how
to automatize. Which event or action can it be assigned to?

If the playing media is stopped due to end of stream:

If Me.AxWindowsMediaPlayer1.playState =
WMPLib.WMPPlayState.wmppsMediaStopped Then
Me.ListBox1.SelectedIndex = Me.ListBox1.SelectedIndex + 1

That code works for a button click action for example, but i want to
automatize selecting next item, without needing to user prompt or user
mouse action. (Like in Windows Media Player's playlist, Winamp's
playlist)
 
kimiraikkonen,

You need an event from your mediaplayer for this which then can be handled.

Have a look in intelisense of the mediaplayer which there are.

Hi,
I looked avaible events with the help of intellisense but only
AxWindowsMediaPlayer1.enter seems valid, but it does not produce
automatize which i want. But a button click does what i wanted if you
assign button1.click action but, as i said i don't want any user
action as normal.

Thanks for the interest.

Hmm... unfortunately I've never to to use the AxWindowsMediaPlayer
active X object so I can't tell you what event to subscribe to. You
might go through the Object Browser and see if you can find any other
events or possible a field or property you can poll to find when it's
finished playing.

Thanks,

Then use that button click and place a label before it, "Next to play".

But everytime song finishes, user is forced to click next button to go
to next selected song. I want it automatic. Possible?

As Cor and Seth said, if there is no event available, it is not possible
automatically.

You could add a Timer and check the state in it's Tick event. If it is
ended, select the next item (as shown).

Hey, I am working on a similar project.
Porting my site http://FullCd.Sytes.Net to asp .net.

This code sniplet handles the media player events, but the events(PlayStateChange & StatusChange) seem to fire off 5 or 6 times for some strange reason, and I do not know ghow to sink these(possibly removeHandler() ). Also I had to use a Session Variable to store the Media Player Object Reference otherwise it loses itself. Please add a reference to WMPLib.dll to the vs2005 project

If I've understood correctly I would have thought the following should do
the trick:

Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged

Dim Filename As String = ListBox1.SelectedItem
AxWindowsMediaPlayer1.URL = Filename
AxWindowsMediaPlayer1.Ctlcontrols.play()
End Sub

Private Sub AxWindowsMediaPlayer1_PlayStateChange(ByVal sender As Object,
ByVal e As AxWMPLib._WMPOCXEvents_PlayStateChangeEvent) Handles
AxWindowsMediaPlayer1.PlayStateChange
If AxWindowsMediaPlayer1.playState = WMPLib.WMPPlayState.wmppsMediaEnded
Then
If ListBox1.SelectedIndex < ListBox1.Items.Count - 1 Then
ListBox1.SelectedIndex = ListBox1.SelectedIndex + 1
Else

'Start at the top of the list again if needed

ListBox1.SelectedIndex = 0

End If

End If

End Sub
