I have a crystal report that I'm attempting to export to pdf programmatically from vb.net. I get the following error message at the 'rpt.export' line:

An unhandled exception of type 'CrystalDecisions.CrystalReports.Engine.LogOnExcep tion' occurred in crystaldecisions.crystalreports.engine.dll

Additional information: Error in File C:\DOCUME~1\RBOHLA~1.BHS\LOCALS~1\Temp\temp_ef3b28 56-3c2c-4602-af2b-66721660df17.rpt:
Unable to connect: incorrect log on parameters.

The crystal report is already displayed in the crviewer when I try to export via a button, so I've already passed by db credentials. Has anyone else seen this?

I have the same problem.. I tried giving access to aspnet account but still it didn't work.. but when I reboot my pc it work for a while.. After 4-5 tries the error reappeared again..

To avoid the above problem in asp.net....

Use the Follwing.......

cp means Crystal report(.rpt file)

 Dim myTable As CrystalDecisions.CrystalReports.Engine.Table
        Dim myLogin As CrystalDecisions.Shared.TableLogOnInfo
       cp.load()

        For Each myTable In cp.Database.Tables
            myLogin = myTable.LogOnInfo
            myLogin.ConnectionInfo.Password = "gis"
            myLogin.ConnectionInfo.UserID = "gis"
            myTable.ApplyLogOnInfo(myLogin)
        Next

wow!... thanks a lot.. it really works!!

Does anyone have a similar fix for VB.net and exporting a crystal report to a MS Word document?

I have the same problem as so many people seem to have and cannot solve it. I checked read/write permissions on my export folder. I even manually send logoninformation to the table I want to use as datasource for the report. I still don't get it.
I use the push model. Have a dataset called dataset1.xsd and crystalreport1.rpt. right mouse click on report: verify datasource works. So reports datasource is synchronized with dataset.

Here is my code:

Dim myConnection As New OleDb.OleDbConnection
        myConnection.ConnectionString = "provider=SQLOLEDB;data source=***;initial catalog=***;user id=***;password=***"
Dim MyCommand As New OleDb.OleDbCommand
MyCommand.Connection = myConnection
MyCommand.CommandText = "Select * From reporte_orden " & Filtro & " "
MyCommand.CommandType = CommandType.Text
Dim MyDA As New OleDb.OleDbDataAdapter
MyDA.SelectCommand = MyCommand
Dim DataSet4Report As New Dataset1
MyDA.Fill(DataSet4Report, "reporte_orden")

Dim crReportDocument As ReportDocument
Dim crExportOptions As ExportOptions
Dim crDiskFileDestinationOptions As DiskFileDestinationOptions

crReportDocument = New CrystalReport1

        Dim Logoninfo As TableLogOnInfo = New TableLogOnInfo
        Dim Conninfo As ConnectionInfo = New ConnectionInfo
        Dim crDatabase As CrystalDecisions.CrystalReports.Engine.Database
        Dim crTables As CrystalDecisions.CrystalReports.Engine.Tables
        Dim crTable As CrystalDecisions.CrystalReports.Engine.Table
        Conninfo.ServerName = "***"
        Conninfo.DatabaseName = "***"
        Conninfo.UserID = "***"
        Conninfo.Password = "***"
        crDatabase = crReportDocument.Database
        crTables = crDatabase.Tables
        crTable = crDatabase.Tables("reporte_orden")
        Logoninfo = crTable.LogOnInfo
        Logoninfo.ConnectionInfo = Conninfo
        crTable.ApplyLogOnInfo(Logoninfo)

        crReportDocument.SetDataSource(DataSet4Report)
        crReportDocument.Load("d:\inetpub\wwwroot\260105\C rystalReport1.rpt")

        crDiskFileDestinationOptions = New DiskFileDestinationOptions
        crDiskFileDestinationOptions.DiskFileName = "d:\exports\" & Session.SessionID.ToString & ".pdf"
        crExportOptions = crReportDocument.ExportOptions
        With crExportOptions
            .DestinationOptions = crDiskFileDestinationOptions
            .ExportDestinationType = ExportDestinationType.DiskFile
            .ExportFormatType = ExportFormatType.PortableDocFormat
        End With

        crReportDocument.Export()

Would be grateful for some help.

Exporting Crystal report ot PDF file use this code.

            CrDiskFileDestinationOptions.DiskFileName = _
                                        "c:\crystalExport.pdf"
            CrExportOptions = cryRpt.ExportOptions
            With CrExportOptions
