IHlinkTarget

A hyperlink target implements the IHlinkTarget interface and gives out hyperlink references to its contents.

When to Implement

Implement this interface when you have an application that can be the target for a hyperlink. In other words, hyperlinks from other applications use this interface to determine how to find, display, and navigate to your target.

An existing OLE document application which supports OLE linking need only implement the IHlinkTarget interface on the same object that implements IPersistFile and IOleItemContainer. The application may also implement IPersistMoniker to support incremental rendering or asynchronous download as a persistence mechanism, rather than IPersistFile.

Note that an ActiveX Document Object need not implement this interface if hyperlink navigation is only occuring within a document object container such as Microsoft Internet Explorer. In such a situation, IHlinkTarget provides the capability to navigate to a location within the document, but it is not necessary for navigation to be completed.

When to Use

You do not normally call these methods directly. When an end user selects a hyperlink through an application’s user interface, the implementation of IHlink::Navigate calls these methods to determine how to display, locate, and navigate to the target.
