[RESOLVED] Media Player forward function not working

Hello,

I have a form with a Media Player object embedded. In the bin folder I have a folder named Movies where are a couple of movie files. I want to read all the files in that folder and make media player run them. For that I created a forward() function that works fine when I press the right arrow key. The problem is that it doesn't work with PlayStateChange event. It simply stops and doesn't read the following file. But if I press the play button it plays the next file. The problem is that I want it to play automatically. Here is the script:

Imports AxWMPLib.AxWindowsMediaPlayer

Public Class Form1
Dim fileNames As New List(Of String)
Dim index As Integer = 0

Private Sub frmPrincipal_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim files = My.Computer.FileSystem.GetFiles("Movies")

fileNames.Clear()
index = 0
For i = 0 To files.Count - 1
fileNames.Add(files(i))
Next

play(index)
End Sub

Private Sub play(ByVal index As Integer)
AxWindowsMediaPlayer1.URL = fileNames(index)
AxWindowsMediaPlayer1.Ctlcontrols.play()
End Sub

Private Sub forward()
index += 1
If index > fileNames.Count - 1 Then
index = 0
End If
play(index)
End Sub

Private Sub backward()
index -= 1
If index < 0 Then
index = fileNames.Count - 1
End If
play(index)
End Sub

Private Sub AxWindowsMediaPlayer1_KeyUpEvent(ByVal sender As System.Object, ByVal e As AxWMPLib._WMPOCXEvents_KeyUpEvent) Handles AxWindowsMediaPlayer1.KeyUpEvent
Select Case e.nKeyCode
Case Keys.Right
forward()
Case Keys.Left
backward()
End Select
End Sub

Private Sub AxWindowsMediaPlayer1_PlayStateChange(ByVal sender As System.Object, ByVal e As AxWMPLib._WMPOCXEvents_PlayStateChangeEvent) Handles AxWindowsMediaPlayer1.PlayStateChange
If e.newState = WMPLib.WMPPlayState.wmppsMediaEnded Then
forward()
End If
End Sub

End Class

ANOTHER PROBLEM is that when in fullscreen mode the KeyUp event doesn't work anymore so I can't advance through the files.

Any help?
Thx

The problem is that it doesn't work with PlayStateChange event.

Have you checked to see that MediaEnded is the actual state at any point in proceedings? I think it unlikely. In any case this is completely the wrong way to go about creating a playlist and navigating through it. That's why they invented the Playlist!

vb.net Code:

Dim plist As IWMPPlaylist = Player.playlistCollection.newPlaylist("play") ' set up a new playlist called (unimaginatively) 'play'
 
        For Each u In urls ' an array of filepaths 
            plist.appendItem(Player.newMedia(u)) ' fill the playlist
        Next
 
        Player.currentPlaylist = plist ' set the media player
        Player.controls.play()  ' play the list
 
        ' to go forward
        Player.controls.next()
 
        ' to go back
        Player.controls.previous()

Helpful, as usual. Thank you. I had to change controls.play to Ctlcontrols.play() in order to make it work.

One last question remains for this subject. For the player "keyup" event I wrote this code:

Select Case e.nKeyCode
Case Keys.Right
player.Ctlcontrols.next()
Case Keys.Left
player.Ctlcontrols.previous()
End Select

This works only if I am not in full screen mode. Any ideea how to make it work also in full screen?

Thx.

I suspect that you'd need to register a hotkey combination for that. In full screen mode I believe the control is overridden to the extent that it is no longer a recipient of key events.

I understand. Now I'll have to figure out how to do that. Thanks.
