注释

The Script component developer does not use the ScriptComponent class directly, but indirectly, by coding the methods and properties of the ScriptMain class, which inherits from ScriptComponent through the UserComponent class.

The developer can override the AcquireConnections method in the ScriptMain class to connect to an external data source from a source or destination component.

示例

The following code sample demonstrates how the Script component developer might obtain a SqlConnection by using the AcquireConnections method. For more information, see 了解脚本组件对象模型.

    Dim connMgr As IDTSConnectionManager100
    Dim sqlConn As SqlConnection

    Public Overrides Sub AcquireConnections(ByVal Transaction As Object)

        connMgr = Me.Connections.MyADONETConnection
        sqlConn = CType(connMgr.AcquireConnection(Nothing), SqlConnection)

    End Sub
