GetLastPageNumber in .net

Hi, Here’s the error that I got. Since we’re working usually in French, I’ll leave the error as it appeared. It says, roughly translated: “Error in file […] operation not authorised on related parameter”

{" Erreur dans le fichier FaDetail 6436_7080_{916660D8-FDDF-4696-BBB3-3150E4351AAE}.rpt : Opération non autorisée effectuée sur un paramètre relié."}

With the following line :

i = crReport.FormatEngine.GetLastPageNumber(New CrystalDecisions.Shared.ReportPageRequestContext) So, just for you to know, my reports contains a lot of sub-reports (approx. 20)

Here’s a sample code in vb.net:

Private Sub Form1_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load       

Dim crDiskFileDestinationOptions As New DiskFileDestinationOptions        

Dim crReportDetail As New CrystalDecisions.CrystalReports.Engine.ReportDocument       

Dim crReportSommr As New CrystalDecisions.CrystalReports.Engine.ReportDocument       

Dim i As Integer       

Try           

     crReportDetail.Load("D:\Applprod\Sige\Rapport\FaDetail.rpt", OpenReportMethod.OpenReportByTempCopy)            

     SetDBLogonForReport(crReportDetail)            

     bFactDetlInitParams(crReportDetail)           

     i = crReportDetail.FormatEngine.GetLastPageNumber(New CrystalDecisions.Shared.ReportPageRequestContext)                  crReportDetail.ExportToDisk(ExportFormatType.PortableDocFormat, "D:\Applprod\Sige\TEMP\Detail.pdf")       

Catch ex As Exception           

     MsgBox(ex.Message)       

End Try

End Sub

Thanks lot.
