The IOleControlSite interface provides the methods that enable a site object to manage each embedded control within a container. A site object provides IOleControlSite as well as other site interfaces such as IOleClientSite and IOleInPlaceSite. When a control requires the services expressed through this interface, it will query one of the other client site interfaces for IOleControlSite.
When to Implement
Implement this interface on an in-place capable site object to support the embedding of controls in the site.
When to Use
A control uses this interface to work with a control-aware container.
