MSHTML Classes: CDoc

The CDoc class is the shared internal representation of the HTADoc, HTMLDocument, HTMLPluginDocument, HTMLPopupDoc and MHTMLDocument classes.

Interfaces

The CDoc class implements some interfaces directly:

• DataSource
• ICustomDoc
• IDataObject
• IDisplayServices
• IHighlightRenderingServices
• IHlinkTarget
• IIMEServices
• IMarkupServices2 and its base IMarkupServices
• IMarqueeInfo
• IMonikerProp
• IObjectIdentity
• IObjectSafety
• IObjectWithSite
• IOleCache2 and its base IOleCache
• IOleCommandTarget
• IOleControl
• IOleDocument
• IOleDocumentView
• IOleInPlaceObjectWindowless and its bases IOleInPlaceObject and IOleWindow
• IOleInPlaceActiveObject
• IOleObject
• IPerPropertyBrowsing
• IPersistFile and its base IPersist
• IPersistHistory
• IPersistMoniker
• IPersistStreamInit
• IPointerInactive
• IPrivacyServices
• IProvideMultipleClassInfo and its bases IProvideClassInfo2 and IProvideClassInfo
• IQueryPopupMgr
• IServiceProvider
• ISpecifyPropertyPages
• ISupportErrorInfo
• ITargetContainer
• IUnknown
• IViewObjectEx and its bases IViewObject2 and IViewObject
• IXMLGenericParse

some more by aggregating CDocument:

• IConnectionPointContainer
• IDispatchEx and its base IDispatch
• IHTMLDocument2 and its base IHTMLDocument
• IHTMLDocument3
• IHTMLDocument4
• IHTMLDocument5
• IInternetHostSecurityManager
• IOleItemContainer and its bases IOleContainer and IParseDisplayName

some more by aggregating CMarkup:

• IHTMLChangePlayback
• IMarkupContainer2 and its base IMarkupContainer
• IMarkupTextFrags

There are also some significant special cases. If a CDoc instance is queried for any non-dual dispatch interface whose DIID has the form {3050F5xx-98B5-11CF-BB82-00AA00BDCE0B} where xx ranges from 00 up to but not including A0, the effect is equivalent to querying for IHTMLDocument2. Also, a CDoc instance accepts CLSID_HTMLDocument and CLSID_CMarkup as interface IDs.
