Crystal Reports exportation Error (Urgent)

Hello. I have an application that utilises crystal reports and displays the report in the report viewer. I have written code that export the report into an excel file.

code:

Code:

---

Private Sub tsbtnExcel_Click(sender As System.Object, e As System.EventArgs) Handles tsbtnExcel.Click

        Try
            Dim CrExportOptions As ExportOptions
            Dim CrDiskFileDestinationOptions As New DiskFileDestinationOptions()
            Dim CrFormatTypeOptions As New ExcelFormatOptions()
            CrDiskFileDestinationOptions.DiskFileName = "bakelist.xls"
            CrExportOptions = cryRpt.ExportOptions
            CrExportOptions.ExportDestinationType = ExportDestinationType.DiskFile
            CrExportOptions.ExportFormatType = ExportFormatType.Excel
            CrExportOptions.DestinationOptions = CrDiskFileDestinationOptions
            CrExportOptions.FormatOptions = CrFormatTypeOptions
            cryRpt.Export()
        Catch ex As Exception
            Throw (ex)
        End Try

    End Sub

---

However the button fails to execute. The code keeps catching and throwing the exception, plus I keep getting the following following error message:

Method not found: 'CrystalDecisions.ReportAppServer.DataDefModel.PropertyBag CrystalDecisions.ReportAppServer.ReportDefModel.ISCRExportOptions.get_ExportOptionsEx()

Does anybody now how to combat this error.

Never used it, but I would point out that you have supplied a filename, but no path.
