使用 .net 与 Libre Office 合并邮件

Question

我有以下代码块，它非常适合 OpenOffice SDK 以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 注册的数据源中。但是现在当我尝试使用它时，oServiceManager = CreateObject("com.sun.star.ServiceManager") 行会生成错误“创建 ActiveX 对象时出错”。 有谁知道，我该如何解决这个问题。

这段代码看起来不正确，所以我很惊讶它居然能奏效。在其他示例中，bootstrap() 行始终排在第一位。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 处的 Java 代码。

你快到了。 getByName() 方法返回 uno.Any，它有一个名为 Value 的属性，DirectCast 可以使用该属性。

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)
