# IOleUILinkInfo

The IOleUILinkInfo interface is an extension of the IOleUILinkContainer interface. It returns the time that an object was last updated, which is link information that IOleUILinkContainer does not provide.

##### When To Implement

You must implement this interface so your container can support the “Link” page of the Object Properties dialog box. If you are writing a container that does not implement links, you do not need to implement this interface.
