           CrystalReportViewer.Search
         Dim eventLog As New EventLog("event.log")
         Dim eventMsg As String = _
         "Search event:" & vbCrLf & _
         "Direction: " & e.Direction().ToString & vbCrLf & _
         "PageNumberToBeginSearch: " & e.PageNumberToBeginSearch() & vbCrLf & _
         "TextToSearch: " & e.TextToSearch()
         eventLog.WriteEntry(eventMsg)
         e.Handled = False
      End Sub
      

      private void LogSearchEvent(Object source, 
      CrystalDecisions.Windows.Forms.SearchEventArgs e)
      {
