返回时，水晶报表仍支持ActiveX，我们有被建成使用ODBC数据源点到Access或SQL数据库水晶报表。在运行时，我们会改变报告中使用OLE DB（ADO），而不是ODBC，更改服务器名称，数据库名称，用户名，密码，特定于用户的，并运行报告，它工作得很好。

Back when Crystal Reports still supports ActiveX, we have crystal reports that were built to use ODBC data source point to an Access or SQL database. In run time, we would change the report to use OLE DB (ADO) instead of ODBC, change the server name, database name, username, password to ones specific to the user, and run the report, it worked fine.

现在的Crystal Reports 2008不再支持ActiveX，我们正在试图做同样的事情在.NET，但没有成功。

Now that Crystal Reports 2008 no longer supports ActiveX, we're trying to do the same thing in .NET, but without success.

这里的code到目前为止：

Here's the code so far:

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

在code工作，直到它到达boReportDocument.VerifyDatabase（），当我得到一个登录失败错误的。

The code works until it gets to boReportDocument.VerifyDatabase(), that's when I get a 'Log On Failed' error.

我试着用code在这里也：

I tried using the code in here as well:

http://stackoverflow.com/questions/1411783/dynamically-change-the-connection-of-a-crystal-report

这是没有任何工作，我不知道是否有做与ODBC切换到OLE DB（ADO）

That didn't work either, I don't know whether it has to do with switching from ODBC to OLE DB (ADO)

推荐答案

我意识到这个问题是3岁和OP可能已经移动了，但也许这可以帮助别人寻找答案。

I realize this question is 3 years old and the OP probably already moved on, but maybe this can help someone else looking for answers.

这是加载从VB.NET报表更改连接信息和其他的东西，如参数值，从工作应用程序中抽取并简化日常用于从多个数据源报告的一个完整的例子：

This is a full example of loading a Report from VB.NET changing the connection info and other stuff like Parameter values, taken and simplified from a working application used daily for reporting from multiple datasources:
