Commenti

Gli sviluppatori di componenti possono fornire un'interfaccia utente per un componente di flusso dati specificando un Tipo e implementando questa interfaccia nella UITypeName proprietà dell'attributo DtsPipelineComponentAttribute . Il designer chiama i metodi di questa interfaccia quando il componente viene aggiunto, eliminato e modificato all'interno del SSIS Designer.
