使用 .net 与 Libre Office 进行邮件合并

我有以下代码块，它非常适合 OpenOffice SDK 来自动化邮件合并功能。

    Public Function runQueryOnDataSource(ByVal nameOfdDtaource As String, ByVal query As String) As Boolean
    strLog = strLog + vbCrLf + Now.ToString() + ": runQueryOnDataSource nameOfdDtaource:" + nameOfdDtaource + ",query:" + query + "-Started"
    Dim oDB As Object, oBase As Object
    Dim oStatement As Object
    Dim rSQL As String
    Dim oRequete As Object
    Dim oServiceManager As Object, CreateUnoService As Object
    Try
        'Creation instance Open office
        oServiceManager = CreateObject("com.sun.star.ServiceManager")
        CreateUnoService = oServiceManager.createInstance("com.sun.star.sdb.DatabaseContext")
        mxMSFactory = (uno.util.Bootstrap.bootstrap()).getServiceManager()
        oDB = CreateUnoService.getByName(nameOfdDtaource) 'oDB=XDataSource
        'Connection
        oBase = oDB.getConnection("", "")   'oBase=XConnection
        oStatement = oBase.createStatement  'XStatement
        'rSQL = "SELECT * FROM ""26_MailMergeResult_DEMO"
        rSQL = query
        oRequete = oStatement.execute(rSQL)
        Return True
    Catch ex As Exception
        strLog = strLog + vbCrLf + Now.ToString() + ": Exception" + ex.ToString()
        Throw ex
    Finally
        oDB = Nothing
        oBase.Close()
        oBase.Dispose()
    End Try
    strLog = strLog + vbCrLf + Now.ToString() + ": runQueryOnDataSource-Finished"
    Return True
End Function

上面的代码用于将数据插入到已经在 libre office 注册的 DataSource 中。但是现在当我尝试使用它时，行oServiceManager = CreateObject("com.sun.star.ServiceManager")生成错误“错误创建 ActiveX 对象”。有没有人有想法，我该如何解决这个问题。

这段代码看起来不正确，所以我很惊讶它曾经工作过。在其他示例中，该bootstrap()行总是先行。然后使用该服务管理器而不是单独的oServiceManager变量。

例如，请参阅https://www.openoffice.org/udk/common/man/spec/transparentofficecomponents.html 上的 Java 代码。

编辑：

你快到了。该getByName()方法返回uno.Any，其中有一个叫做财产Value即DirectCast可以使用。

Dim oDB As XDataSource
Dim oBase As XConnection = Nothing
Dim xContext As XComponentContext = uno.util.Bootstrap.bootstrap()
Dim xMSFactory As XMultiServiceFactory = DirectCast(
    xContext.getServiceManager(), XMultiServiceFactory)
Dim xNameAccess As XNameAccess = DirectCast(
    xMSFactory.createInstance("com.sun.star.sdb.DatabaseContext"), XNameAccess)
oDB = DirectCast(xNameAccess.getByName("Bibliography").Value, XDataSource)
oBase = DirectCast(oDB.getConnection("", ""), XConnection)
