ASP.Net Help |
|
|
I'm hoping someone can help with a small problem I am encountering with an
ASP.NET app. Basically, I am trying to bind an Album's track list to a
datagrid. Things work fine, except that the first track information in the
datagrid is wrong. For example, it is listed as:
01 The Song Remains the Same
In addition, for the first track the album information, such as author,
album and duration is not displayed. It currently looks like the following
(this is for Led Zeppelin's album "Houses of the Holy" but it happens with
all albums).
Title Author Album Duration
01 The Song Remains the Same 0:00
The Rain Song Led Zeppelin Houses of the Holy 7:40
Over the Hills and Far Away Led Zeppelin Houses of the Holy 4:50
The Crunge Led Zeppelin Houses of the Holy 3:15
Dancing Days Led Zeppelin Houses of the Holy 3:45
D'Yer Mak'er Led Zeppelin Houses of the Holy 4:25
No Quarter Led Zeppelin Houses of the Holy 7:04
The Ocean Led Zeppelin Houses of the Holy 4:31
Here's the code that produces this. What's the problem? Thanks in advance.
Private Sub BindTracks()
Dim albumPath As String = Request.Item("albumpath")
Dim m As New WMPLib.WindowsMediaPlayer
Dim mi As WMPLib.IWMPMedia
Dim di As New IO.DirectoryInfo(albumPath)
For Each fi As IO.FileInfo In di.GetFiles("*.wma")
mi = m.newMedia(fi.FullName)
m.currentPlaylist.appendItem(mi)
Next
Dim table As New DataTable
table.Columns.Add("Title")
table.Columns.Add("Author")
table.Columns.Add("Album")
table.Columns.Add("Duration")
Dim row As DataRow
For i As Integer = 0 To m.currentPlaylist.count - 1
row = table.NewRow
row("Title") = m.currentPlaylist.Item(i).getItemInfo("Title")
row("Author") = m.currentPlaylist.Item(i).getItemInfo("Author")
row("Album") = m.currentPlaylist.Item(i).getItemInfo("Album")
row("Duration") = m.currentPlaylist.Item(i).durationString
table.Rows.Add(row)
Next
Me.dgTracks.DataSource = table
Me.dgTracks.DataBind()
End Sub

I can't see anything obvious - the code seems logical enough. What
happens if you move the 'row = table.NewRow' outside the loop (so that
you're just setting the attributes of the row on each iteration) ?
That's still valid ASP.Net, right ?
It looks to me like the fields in the first row of the datagrid are
misaligned, as I've not experienced any problem with WMP in this
regard (and you are using zero-indexed items, which is correct)

Thanks Neil.
I can move the row = table.NewRow outside the loop, but that's going to
cause a problem because there may be several tracks for an album and each
track should be stored in it's own row. Hmm. I'm beginning to wonder if this
may be a bug with the ActiveX control method. Who knows? Thanks again for
your help.

Well, therre's nothing wrong with the documented ActiveX controls,
cause I've been using them to extract similar data, but using
javascript ;-)
(My problem is currently processing huge XML files derived from the
media library, in an acceptable way - my server is barfing on them !)
