Hinweise

In Integration Services, this attribute allows you to specify how expensive it is to recreate a specific user interface. For example, if a user interface displays a drop-down list with only five fields, all obtained from the local computer, the user interface may be fairly fast and inexpensive to process. However, if a drop-down list in a user interface contains information that was gathered from a remote server, or from across a network that was slow, the user interface may be expensive and time-consuming to re-create. To keep the user interface in memory until the package designer is closed, set the TaskUILifetimeHint property to RecreationExpensive. To dispose of the user interface as soon as the user closes the dialog, set the TaskUILifetimeHint property to RecreationInexpensive.

Threadsicherheit

Alle öffentlichen static (Shared in Visual Basic)-Elemente dieses Typs sind Threadsicher. Für Instanzelemente wird die Threadsicherheit nicht gewährleistet.
