      private DateTimeFieldFormat getDateTimeFieldFormat
         (String reportObjectName)
      {
         FieldObject field;
         DateTimeFieldFormat dateTimeFormat = null;
         try
         {
            field = (FieldObject)Report.get_ReportDefinition()
               .get_ReportObjects().get_Item(reportObjectName);
            if (field.get_DataSource().get_ValueType() ==
               FieldValueType.DateTimeField)
               dateTimeFormat = field.get_FieldFormat().get_DateTimeFormat();
         }
         catch (Exception e)
         {
         }
         return dateTimeFormat;
      }
