public SampleVirtualFile(string virtualPath, SamplePathProvider provider)
  : base(virtualPath)
  this.spp = provider;

protected void GetData()
  // Get the data from the SamplePathProvider
  DataSet ds = spp.GetVirtualData();

  // Get the virtual file from the resource table.
  DataTable files = ds.Tables["resource"];
  DataRow[] rows = files.Select(
    String.Format("(name = '{0}') AND (type='file')", this.Name));

  // If the select returned a row, store the file contents.
  if (rows.Length > 0)
    DataRow row = rows[0];

    content = row["content"].ToString();
