catch Media Player Error

[sonia sardana]

I m selecting the folder & playing all the files in the media player, of that folder. As u know folder contains all types of files including text,zip,image & so on.

So I want that when URL that is assigned to Media Player is .txt,then i assign any default image from resources.

I do not want to check extensions-
Currently I m checking the extension of each file before paying but i dont want dat.

Catch the media player error

' Try to play a text file
AxWindowsMediaPlayer1.URL = "D:\test.txt"
.
.
Private Sub AxWindowsMediaPlayer1_ErrorEvent(ByVal sender As Object, ByVal e As System.EventArgs) Handles AxWindowsMediaPlayer1.ErrorEvent
  ' Catch player errors
  Dim oErrorItem As WMPLib.IWMPErrorItem

  If CType(sender, AxWMPLib.AxWindowsMediaPlayer).Error.errorCount > 0 Then
    oErrorItem = CType(sender, AxWMPLib.AxWindowsMediaPlayer).Error.Item(0)
    If oErrorItem.errorCode = -1072885353 Then
      MsgBox("Invalid file")
    End If
  End If

End Sub

That error code was returned when the media player couldn't decode the file (text file in this case). I didn't check any documentation or test the code any further, but the same error code may be returned by some other error condition.

Sir its not working..

its not working

In what way it isn't working? Any error messages? Please be more specific.

Or do you mean it's not working "as is". It wasn't suppose to. You have to modify it slightly for your application. Instead of MsgBox("Invalid file") , write AxWindowsMediaPlayer1.URL = My.Resources.PlayListImage .

[Teme64]

By the way. You can't assign Image type to String type like you do in WindowsMediaPlayer.URL = My.Resources.PlayListImage . Url property takes a path to a file. Save your image resource first to some temporary file.

Private m_TempImageFileName As String

Private Sub Form2_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
  ' 
  m_TempImageFileName = My.Computer.FileSystem.GetTempFileName & ".jpg"
  Try
    My.Resources.BlogImage.Save(m_TempImageFileName, System.Drawing.Imaging.ImageFormat.Jpeg)
  Catch ex As Exception
    ' Handle I/O error(s)
  End Try

End Sub

Private Sub AxWindowsMediaPlayer1_ErrorEvent(ByVal sender As Object, ByVal e As System.EventArgs) Handles AxWindowsMediaPlayer1.ErrorEvent
  ' Catch player errors
  Dim oErrorItem As WMPLib.IWMPErrorItem

  If CType(sender, AxWMPLib.AxWindowsMediaPlayer).Error.errorCount > 0 Then
    oErrorItem = CType(sender, AxWMPLib.AxWindowsMediaPlayer).Error.Item(0)
    If oErrorItem.errorCode = -1072885353 Then
      CType(sender, AxWMPLib.AxWindowsMediaPlayer).Error.clearErrorQueue()
      CType(sender, AxWMPLib.AxWindowsMediaPlayer).URL = m_TempImageFileName
    End If
  End If

End Sub

Y u r right i cannot assign resource image to URL...Oops i was wrong...

    End Sub

    Private Sub AxWindowsMediaPlayer1_ErrorEvent(ByVal sender As Object, ByVal e As System.EventArgs) Handles AxWindowsMediaPlayer1.ErrorEvent
        Dim oErrorItem As WMPLib.IWMPErrorItem
        If CType(sender, AxWMPLib.AxWindowsMediaPlayer).Error.errorCount > 0 Then
            oErrorItem = CType(sender, AxWMPLib.AxWindowsMediaPlayer).Error.Item(0)
            If oErrorItem.errorCode = -1072885353 Then
                MsgBox("Invalid file")
            End If
        End If

When the form is loaded,error is there which is thrown by media player,

file you ware attempting to play has an extension .txt that does not match the file format.

Control never goes to WIndows Media error event.....

[Teme64]

file you ware attempting to play has an extension .txt that does not match the file format.

Yes, that's not exactly an error. It's more like a warning that media player control can't decode the file. If you press Yes-button, the player will try to play the file and ends up raising the error.

You don't want any user interaction, am I right? I don't know how to suppress that warning and force the player to play the file anyway (I'm sure there's a way to do that).

In your original post you declared each acceptable file extension as a separate string. You could use an array instead, load extension from a text file and loop the extension array to determine (by file's extension) if the control will try to play it. And by the way, the original If...Then...Else...End If will fail with (legal) extensions like .Avi or .AVI. Instead of trimming (it's obsolete, there's no spaces) you should make a not case-sensitive comparison like sExtension.ToUpper = sExe_avi.ToUpper .
