Crystal Report not Exporting On website

Hi Good Day All,

I have this code for exporting my crystal report to excel, but it doesn't export anything and it just tells me that it was successful, please what can i do. This is my code:

Protected Sub ImgBtExcel_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles ImgBtExcel.Click
        Dim objReportOptions As New ExportOptions
        Dim objDiskFileDestinationOptions As New DiskFileDestinationOptions()
        Dim objFormatTypeOptions As New ExcelFormatOptions
        Dim strFileName As String = "C:\Reports\WatchDog" & Now.ToLongDateString & ".xls"

        Try
            If strFileName IsNot Nothing Then

                If Not System.IO.Directory.Exists("C:\Reports\") Then
                    System.IO.Directory.CreateDirectory("C:\Reports\")
                End If

                objDiskFileDestinationOptions.DiskFileName = strFileName
                objReportOptions.ExportDestinationType = ExportDestinationType.DiskFile
                objReportOptions.ExportFormatType = ExportFormatType.Excel
                objFormatTypeOptions.ExcelUseConstantColumnWidth = False
                objReportOptions.DestinationOptions = objDiskFileDestinationOptions
                objReportOptions.FormatOptions = objFormatTypeOptions

                objReports.Export(objReportOptions)
                'MsgBox("Export Successful")
                Response.Write("Report Exported Successfully, Please check your C:\Reports\ Folder. Thanks")
            End If
        Catch ex As Exception

        End Try
    End Sub

Thanks
