Как изменить свойства подключения Crystal Reports в коде?

Question

Назад, когда Crystal Reports по-прежнему поддерживает ActiveX, у нас есть Crystal Reports, созданные для использования источника данных ODBC, указывающего на базу данных Access или SQL. Во время выполнения мы изменили бы отчет, чтобы использовать OLE DB (ADO) вместо ODBC, изменили имя сервера, имя базы данных, имя пользователя и пароль на индивидуальные для пользователя, и запустили отчет, он работал нормально.

Теперь, когда Crystal Reports 2008 больше не поддерживает ActiveX, мы пытаемся сделать то же самое в .NET, но безуспешно.

Вот код на данный момент:

Public Function ChangeConnectionInfo() As ReportDocument
        Dim boReportDocument As New ReportDocument
        '**EDIT** Change the path and report name to the report you want to change.
        boReportDocument.Load("c:\CustomerListSQL.Rpt", OpenReportMethod.OpenReportByTempCopy)

        'Create a new Command Table to replace the reports current table.
        Dim boTable As New CrystalDecisions.ReportAppServer.DataDefModel.CommandTable

        'boMainPropertyBag: These hold the attributes of the tables ConnectionInfo object
        Dim boMainPropertyBag As New PropertyBag
        'boInnerPropertyBag: These hold the attributes for the QE_LogonProperties
        'In the main property bag (boMainPropertyBag)
        Dim boInnerPropertyBag As New PropertyBag

        'Set the attributes for the boInnerPropertyBag
        boInnerPropertyBag.Add("Auto Translate", "-1")
        boInnerPropertyBag.Add("Connect Timeout", "15")
        boInnerPropertyBag.Add("Data Source", "K2")
        boInnerPropertyBag.Add("General Timeout", "0")
        boInnerPropertyBag.Add("Initial Catalog", "DBNAME")
        boInnerPropertyBag.Add("Integrated Security", "True")
        boInnerPropertyBag.Add("Locale Identifier", "5129")
        boInnerPropertyBag.Add("OLE DB Services", "-5")
        boInnerPropertyBag.Add("Provider", "SQLOLEDB")
        boInnerPropertyBag.Add("Tag with column collation when possible", "0")
        boInnerPropertyBag.Add("Use DSN Default Properties", "False")
        boInnerPropertyBag.Add("Use Encryption for Data", "0")

        'Set the attributes for the boMainPropertyBag
        boMainPropertyBag.Add("Database DLL", "crdb_ado.dll")
        boMainPropertyBag.Add("QE_DatabaseName", "DBNAME")
        boMainPropertyBag.Add("QE_DatabaseType", "OLE DB (ADO)")
        'Add the QE_LogonProperties we set in the boInnerPropertyBag Object
        boMainPropertyBag.Add("QE_LogonProperties", boInnerPropertyBag)
        boMainPropertyBag.Add("QE_ServerDescription", "K2")
        boMainPropertyBag.Add("QE_SQLDB", "True")
        boMainPropertyBag.Add("SSO Enabled", "False")

        'Create a new ConnectionInfo object
        Dim boConnectionInfo As New CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo
        'Pass the database properties to a connection info object
        boConnectionInfo.Attributes = boMainPropertyBag
        'Set the connection kind
        boConnectionInfo.Kind = CrConnectionInfoKindEnum.crConnectionInfoKindCRQE
        '**EDIT** Set the User Name and Password if required.
        'boConnectionInfo.UserName = "UserName"
        'boConnectionInfo.Password = "Password"
        'Pass the connection information to the table
        boTable.ConnectionInfo = boConnectionInfo

        'Get the Database Tables Collection for your report
        Dim boTables As CrystalDecisions.ReportAppServer.DataDefModel.Tables = _
           boReportDocument.ReportClientDocument.DatabaseController.Database.Tables    

        'For each table in the report:
        ' - Set the Table Name properties.
        ' - Set the Command table's command text.
        ' - Set the table location in the report to use the new modified table
        For Each boReportTable In boTables
            boTable.Name = boReportTable.Name
            boTable.QualifiedName = "DBNAME.dbo." + boReportTable.Name 'boReportTable.QualifiedName
            boTable.Alias = boReportTable.Alias    
            boReportDocument.ReportClientDocument.DatabaseController.SetTableLocation(boReportTable, boTable)
        Next

        'Verify the database after adding substituting the new table.
        'To ensure that the table updates properly when adding Command tables or Stored Procedures.
        boReportDocument.VerifyDatabase()

        Return boReportDocument
    End Function

Код работает, пока не доходит до boReportDocument.VerifyDatabase (), вот тогда я получаю ошибку «Ошибка входа в систему».

Я тоже пытался использовать код здесь:

Динамически изменить подключение Crystal Report

Это тоже не сработало, я не знаю, связано ли это с переключением с ODBC на OLE DB (ADO)

Answer 1

Я понимаю, что этому вопросу уже 3 года, и ОП, вероятно, уже перешел, но, возможно, это может помочь кому-то еще искать ответы.

Это полный пример загрузки отчета из VB.NET с изменением информации о соединении и других вещей, таких как значения параметров, взятых и упрощенных из рабочего приложения, которое ежедневно используется для составления отчетов из нескольких источников данных:

Private Sub ReportGo()
        'Main Report 
        Dim crxRpt As New CrystalDecisions.CrystalReports.Engine.ReportDocument
        'Subreport objects, if you need them
        Dim crxSubrpt1 As New CrystalDecisions.CrystalReports.Engine.ReportDocument, crxSubrpt2 As New CrystalDecisions.CrystalReports.Engine.ReportDocument
        'Parameter fields objects and values, if you need them
        Dim crxPar1 As New CrystalDecisions.Shared.ParameterField
        Dim crxVal1 As New CrystalDecisions.Shared.ParameterDiscreteValue

        'Load report file
        crxRpt.Load("myreport.rpt")

        'Load subreports, if you have them. Otherwise comment these lines
        crxSubrpt1 = crxRpt.OpenSubreport("MySubr1")
        crxSubrpt2 = crxRpt.OpenSubreport("MySubr2")

        'Login Main Report
        Dim myTables As CrystalDecisions.CrystalReports.Engine.Tables = crxRpt.Database.Tables
        crxRpt.SetDatabaseLogon("Username", "Password", "Servername", "Database") 
        Dim crConnInfo1 As CrystalDecisions.Shared.ConnectionInfo = New CrystalDecisions.Shared.ConnectionInfo
        crConnInfo1.DatabaseName = "Database"
        crConnInfo1.UserID = "Username"
        crConnInfo1.Password = "Password"
        crConnInfo1.ServerName = "Servername"

        'If your report uses more than one datasource, then uncomment and add the other login info here: 
        'crxRpt.SetDatabaseLogon("Username2", "Password2", "Servername2","Database2")
        'Dim crConnInfo2 As CrystalDecisions.Shared.ConnectionInfo = New CrystalDecisions.Shared.ConnectionInfo

                myTableLogonInfo.ConnectionInfo = crConnInfo1
                myTable.ApplyLogOnInfo(myTableLogonInfo)
            Else
                'This here only applies if you have more than one datasource
                'myTableLogonInfo.ConnectionInfo = crConnInfo2
                'myTable.ApplyLogOnInfo(myTableLogonInfo)
            End If
        Next

        'Subreport Login. Comment this section if you don't use them
        crxSubrpt1.SetDatabaseLogon("Username", "Password","Servername", "Database")
        'again, only if you use 2 datasources
        'crxSubrpt1.SetDatabaseLogon("Username2", "Password2", "Servername2", "Database2")
        crxSubrpt1.RecordSelectionFormula = "Subreport 1 Selection formula goes here"
        crxSubrpt2.SetDatabaseLogon("Username", "Password","Servername", "Database")
        'again, only if you use 2 datasources
        'crxSubrpt2.SetDatabaseLogon("Username2", "Password2", "Servername2", "Database2")
        crxSubrpt2.RecordSelectionFormula = "Subreport 2 selection formula goes here"

        Dim mySections As CrystalDecisions.CrystalReports.Engine.Sections = crxRpt.ReportDefinition.Sections
        For Each mySection As CrystalDecisions.CrystalReports.Engine.Section In mySections
            Dim myReportObjects As CrystalDecisions.CrystalReports.Engine.ReportObjects = mySection.ReportObjects
            For Each myReportObject As CrystalDecisions.CrystalReports.Engine.ReportObject In myReportObjects
                If myReportObject.Kind = CrystalDecisions.Shared.ReportObjectKind.SubreportObject Then
                    Dim mySubreportObject As CrystalDecisions.CrystalReports.Engine.SubreportObject = CType(myReportObject, CrystalDecisions.CrystalReports.Engine.SubreportObject)
                    Dim subReportDocument As CrystalDecisions.CrystalReports.Engine.ReportDocument = mySubreportObject.OpenSubreport(mySubreportObject.SubreportName)
                    Dim mytablessub As CrystalDecisions.CrystalReports.Engine.Tables = subReportDocument.Database.Tables
                        For Each myTable As CrystalDecisions.CrystalReports.Engine.Table In mytablessub
                            Dim myTableLogonInfo As CrystalDecisions.Shared.TableLogOnInfo = myTable.LogOnInfo
                            If myTable.LogOnInfo.ConnectionInfo.DatabaseName = "Database" Then
                                myTableLogonInfo.ConnectionInfo = crConnInfo1
                                myTable.ApplyLogOnInfo(myTableLogonInfo)
                            Else
                                'Only if you use 2 datasources
                                'myTableLogonInfo.ConnectionInfo = crConnInfo2
                                'myTable.ApplyLogOnInfo(myTableLogonInfo)
                            End If
                        Next
                    End If
                Next

        'crxPar1.Name = "Parameter 1 name" 
        'crxPar1.CurrentValues.Add(crxVal1)
        'crxPar1.HasCurrentValue = True

        'Apply main report selection formula
        crxRpt.RecordSelectionFormula = "Main report selection formula goes here"
        crxRpt.Refresh()


        'Now, if you preview the report in your VB app with a CrystalReportViewer, uncomment this:
        'YourForm.CristalReportViewer.ReportSource = crxRpt 

        'If you use Parameter fields...
        'YourForm.CrystalReportViewer.ParameterFieldInfo.Clear()
        'YourForm.CrystalReportViewer.ParameterFieldInfo.Add(crxPar1)

        'Finally, if you need to export the report automatically
         CrxRpt.ExportToDisk(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat, "Yourfile.pdf")

End Sub

Answer 2

Этот метод можно просто использовать для входа в любой отчет Crystal Report.

Просто передайте ваши параметры:

 Public Sub LogOn(ByVal poReport As CrystalDecisions.CrystalReports.Engine.ReportDocument, ByVal strServer As String, ByVal strTable As String, ByVal strUsername As String, ByVal strPassword As String)
    Dim loConnInfo As New CrystalDecisions.Shared.ConnectionInfo
    loConnInfo.ServerName = strServer
    loConnInfo.DatabaseName = strTable
    loConnInfo.UserID = strUsername
    loConnInfo.Password = strPassword
    loConnInfo.IntegratedSecurity = False
    Dim loTables As CrystalDecisions.CrystalReports.Engine.Tables
    Dim loTable As CrystalDecisions.CrystalReports.Engine.Table
    Dim loTableLogonInfo As CrystalDecisions.Shared.TableLogOnInfo
    loTables = poReport.Database.Tables

    For Each loTable In loTables
        loTableLogonInfo = loTable.LogOnInfo
        loTableLogonInfo.ConnectionInfo.UserID = strUsername
        loTableLogonInfo.ConnectionInfo.Password = strPassword
        loTableLogonInfo.ConnectionInfo.ServerName = strServer
        loTableLogonInfo.ConnectionInfo.DatabaseName = strTable
        loTableLogonInfo.ConnectionInfo.IntegratedSecurity = False
        loTable.ApplyLogOnInfo(loTableLogonInfo)
    Next
End Sub

И назовите это так:

LogOn(yourReportDocument, serverPath, databaseName, userName, password)
