System.Exception Error text:The operation completed successfully

Question

Hi
I have the this code :
try
oRpt1.PrintToPrinter(1, False, 0, 0)
Catch erros As CrystalDecisions.CrystalReports.Engine.InternalException
            WebConfig.Erro = "RPT: Engine: " & erros.Message
            Return False
        Catch erros2 As CrystalDecisions.CrystalReports.Engine.PrintException
            WebConfig.Erro = "RPT: Engine: " & erros2.Message
            Return False
        Catch erros4 As CrystalDecisions.CrystalReports.Engine.LogOnException
            WebConfig.Erro = "RPT: Engine: " & erros4.Message
            Return False
        Catch erros3 As CrystalReportsException
            WebConfig.Erro = "RPT: Engine: " & erros3.Message
            Return False
        Catch erros5 As CrystalDecisions.ReportSource.EnterpriseException
            WebConfig.Erro = "RPT: Engine: " & erros5.Message
            Return False
        Catch erros6 As CrystalDecisions.CrystalReports.Engine.OutOfLicenseException
            WebConfig.Erro = "RPT: Engine: " & erros6.Message
            Return False
        Catch erros7 As CrystalDecisions.CrystalReports.Engine.DataSourceException
            WebConfig.Erro = "RPT: Engine: " & erros7.Message
            Return False
        Catch erros8 As CrystalDecisions.CrystalReports.Engine.ExportException
            WebConfig.Erro = "RPT: Engine: " & erros8.Message
            Return False
        Catch erros9 As CrystalDecisions.CrystalReports.Engine.NoReportPartsException
            WebConfig.Erro = "RPT: Engine: " & erros9.Message
            Return False
        Catch erros10 As CrystalDecisions.CrystalReports.Engine.SubreportException
            WebConfig.Erro = "RPT: Engine: " & erros10.Message
            Return False
        Catch erros11 As CrystalDecisions.CrystalReports.Engine.FormulaException
            WebConfig.Erro = "RPT: Engine: " & erros11.Message
            Return False
        Catch erros12 As CrystalDecisions.CrystalReports.Engine.EngineException
            WebConfig.Erro = "RPT: Engine: " & erros12.Message
            Return False
            'Catch erros13 As CrystalDecisions.CrystalReports.Engine.ParameterFieldCurrentValueException
            '    WebConfig.Erro = "RPT: Engine: " & erros13.Message
            '    Return False
        Catch erros1 As System.Exception
            WebConfig.Erro = "RPT: Exception: " & erros1.Message & " " & Nome_Mapa & " " & NomeImpressora
            Return False
        End Try
And the code goes to Erros1 the the messege: -          erros1     {"The operation completed successfully"}     System.Exception
And doesnu2019t print on oRpt1.PrintToPrinter(1, False, 0, 0)
I working with visual studio 2008 (using framwork 2) and a I a impersonaction to print direct to the print, in a web page (ASPX).
This code works fine in visual studio 2005
Open the reports with:
Try
            oRpt1.Load(Nome_Mapa, OpenReportMethod.OpenReportByDefault)
        Catch ex As Exception
            WebConfig.Erro = "RPT ERRO carregar mapa: " & ex.Message & " " & Nome_Mapa & " " & Date.Now.ToString
            Return False
        End Try
I donu2019t recive any error in  this try.
I donu2019t know what do moreu2026

I'd like to see a simple win app work on that system first. You can keep it really simple by running a saved data report, saving you the database logon code. So all you'd need to do is load the report, then .printtoprinter. If that works, I'd like you to try run one of our sample apps, see what it does. The samples are here:
https://smpdl.sap-ag.de/~sapidp/012002523100006252812008E/net_web_smpl.exe
You will get a number of samples, use vbnet_win_printtoprinter. (see how to configure the web app in the readme that comes with the app).
