Замечания

Within the Microsoft Visual Studio 2008 Tools for Applications (VSTA) scripting environment, the Script task provides the global Dts object, which gives the developer programmatic access to objects defined elsewhere in the package, such as connections, variables, and events, through the properties and methods of the ScriptObjectModel class. The Dts object is an instance of the ScriptObjectModel class.

Примеры

The following sample of code for use inside a Script task demonstrates the use of the Variables, Events, and TaskResult properties. For more information, see Запрос Active Directory в задаче «Сценарий».

Public Sub Main()

    Dim directory As DirectoryServices.DirectorySearcher
    Dim result As DirectoryServices.SearchResult
    Dim email As String

    email = Dts.Variables("email").Value.ToString

    Try
        directory = New _
            DirectoryServices.DirectorySearcher("(mail=" & email & ")")
        result = directory.FindOne
        Dts.Variables("name").Value = _
            result.Properties("displayname").ToString
        Dts.Variables("title").Value = _
            result.Properties("title").ToString
        Dts.TaskResult = ScriptResults.Success
    Catch ex As Exception
        Dts.Events.FireError(0, _
            "Script Task Example", _
            ex.Message & ControlChars.CrLf & ex.StackTrace, _
            String.Empty, 0)
        Dts.TaskResult = ScriptResults.Failure
    End Try

End Sub
