This section describes Microsoft ActiveX Hyperlinking and the interfaces involved in adding hyperlink navigation to your document or application.

Overviews/Tutorials

Hyperlinks

This section provides an overview of hyperlinks, a description of the ActiveX Hyperlinking architecture (including the interfaces required to add hyperlink support to an application), and examples. Applications can choose to support various degrees of integration with the ActiveX Hyperlinking architecture. Where applicable, this document describes how to provide minimal or simple hyperlinking support, and also how to extend this support for more complete hyperlinking integration.

Objects

Hyperlink

This object implements, at a minimum, an IHlink interface and acts as a link to an object at another location (the target).

Hyperlink Browse Context

This object implements an IHlinkBrowseContext interface and maintains the navigation stack.

Hyperlink Target

This object implements an IHlinkTarget interface and supplies information that other hyperlink objects use to navigate to the target.

Interfaces

IEnumHLItem

Provides functions for items in the stack list created using the IHlinkBrowseContext::EnumNavigationStack method.

IExtensionServices

Exposes methods that provide additional information to an HTTP request.

IHlink

Provides methods that enable a hyperlink to navigate to its target, access a display name for display purposes, and identify itself to its container and frame.

IHlinkBrowseContext

Allows a Component Object Model (COM) object to define and manage the browse context for an ActiveX hyperlink application.

IHlinkFrame

Provides methods that allow a browser to insert a hyperlink frame in the navigation process.

IHlinkSite

Provides methods for a hyperlink to retrieve the moniker or the interface on its hyperlink container. The navigation process that resolves a hyperlink uses this information to handle internal hyperlink references (in the same container) and external hyperlink references (to a different container).

IHlinkTarget

Implemented by a hyperlink target to provide hyperlink references to the target contents.
