Problem when exporting to Excel

I have written a simple .rpt viewer using the Crystal Report Viewer control in VB.net 2003. When reports are exported using the export button on the control, several alignment and spacing errors are present. However, these formatting errors are not present if I view and export a report using the Crystal Reports software that I use to design the reports. I'm pretty sure that the problem lies with my report viewer program not using the proper .dll. How do I tell my program to use a different dll to export files? Thanks.

The problem is not with the dll.  To get a report to export as you want you need to set it up correctly.  Crystal tries to export the report as it is to Excell but Excel coulmns cause trouble.

I have seen that article, and I don't think it is any help for me, since my reports export to Excel without problems using Crystal Reports 8.5. When I export a program via the Report Viewer control in my viewer application, there are formatting errors, merged cells, misaligned column headers, etc. Also, the gridlines do not appear in the exported excel file. I would rather not have to redesign a large number of reports if I can avoid it. Is there a way to expand the export options packed in with the CrystalReportViewer control in VB.net to be more consistent with the export options present in Crystal Reports?

I don't think so since CR.Net is a stripped down version of CR9.

Also Crystal deliberately limited the export options on some of the viewers to encourage use of the RDC.

I figured out a way to come pretty close to the "data only" export option a la the full Crystal Reports software, using the "Export()" method and adjusting settings that way. In case anyone is interested, my code looked like:

If SaveFileDialog1.ShowDialog() = DialogResult.OK Then
            Dim OpenFile As String
            OpenFile = SaveFileDialog1.FileName

            Report1.ExportOptions.ExportDestinationType = CrystalDecisions.[Shared].ExportDestinationType.DiskFile
            Dim fileOptions As New CrystalDecisions.Shared.DiskFileDestinationOptions
            fileOptions.DiskFileName = OpenFile
            Report1.ExportOptions.DestinationOptions = fileOptions
            Report1.ExportOptions.ExportFormatType = CrystalDecisions.[Shared].ExportFormatType.Excel
            Dim excelOptions As New CrystalDecisions.Shared.ExcelFormatOptions
            excelOptions.ExcelUseConstantColumnWidth = False
            excelOptions.ExcelTabHasColumnHeadings = False
            Report1.ExportOptions.FormatOptions = excelOptions

            Report1.Export()
        End If
