How can I programatically take a file ID and get the URL to pass back to the browser?  So, for example, on Portal ID 0, I have a file in the file table called ball.jpg with an ID of 25.  How can I turn that into the URL the browser would need to download the file.  Security is not an issue.

Thanks.

Perfect - exactly what I was looking for.

Thanks.

Ok, hang on..... I got this from the downloads module, it should help me.

If objDocument.Url.ToLower.IndexOf("fileid=") >= 0 Then
              ' document is a file, check security
              Dim objFiles As New FileController
              Dim objFile As DotNetNuke.Services.FileSystem.FileInfo = objFiles.GetFileById(Integer.Parse(objDocument.Url.Split(Char.Parse("="))(1)), PortalId)

              If Not objFile Is Nothing AndAlso Not DotNetNuke.Security.PortalSecurity.IsInRoles(FileSystemUtils.GetRoles(objFile.Folder, PortalSettings.PortalId, "READ")) Then
                ' remove document from the list
                mobjDocumentList.Remove(objDocument)
              End If
            End If
