尝试在VB .NET中执行DTS包时"无效的类字符串"

Question

我有一个在我们的MS SQL Server 2000数据库服务器上运行的DTS包,并且需要一种方法让用户从他们自己的机器上执行它.(该包创建文件,然后由我的应用程序传输到客户端计算机.)我已在应用程序中包含"Microsoft DTSPackage对象库"COM引用,但在第一步时仍然出现"无效类字符串"错误包执行.我还尝试注册SQL Server 2000光盘的redist.txt文件中指定的所有DLL.任何想法或建议将不胜感激.DTS包非常简单.它只是将SQL数据库中的数据复制到Visual FoxPro表中.我执行该程序包的代码如下(其中大部分内容来自Microsoft的知识库文章:http://support.microsoft.com/kb/321525).

        Dim pkg As DTS.Package
        pkg = New DTS.Package
        Dim cpContainer As System.Runtime.InteropServices.ComTypes.IConnectionPointContainer
        cpContainer = CType(pkg, System.Runtime.InteropServices.ComTypes.IConnectionPointContainer)
        Dim cpPoint As System.Runtime.InteropServices.ComTypes.IConnectionPoint
        Dim PES As PackageEventsSink = New PackageEventsSink

        Dim guid As Guid = New Guid("10020605-EB1C-11CF-AE6E-00AA004A34D5")

        cpPoint = Nothing
        cpContainer.FindConnectionPoint(guid, cpPoint)

        Dim intCookie As Integer
        cpPoint.Advise(PES, intCookie)

        pkg.LoadFromSQLServer(DTS_SERVER_NAME, , , DTSSQLServerStorageFlags.DTSSQLStgFlag_UseTrustedConnection, dtsPassword, , , dtsName, Nothing)
        If pkg Is Nothing Then Throw New ApplicationException("The DTS Package could not be loaded from the SQL Server.")

        Dim pkgStep As DTS.Step
        For Each pkgStep In pkg.Steps
            pkgStep.Execute()
        Next

        pkg.UnInitialize()
        pkg = Nothing

        cpPoint.Unadvise(intCookie)
        cpPoint = Nothing
        cpContainer = Nothing
        PES = Nothing

如果您在用户PC上安装完整的SQL Enterprise Manager客户端工具作为测试，他们能否成功运行？也许您缺少一些要求。请记住，DTS 包本身将在用户的 PC 上本地执行，而不是在服务器上执行。
