ITfRange::GetEmbedded method

The ITfRange::GetEmbedded method obtains content that corresponds to a TS_CHAR_EMBEDDED character in the text stream. The start anchor of the range of text is positioned just before the character of interest.

Syntax

C++


HRESULT GetEmbedded(
  [in]  TfEditCookie ec,
  [in]  REFGUID      rguidService,
  [in]  REFIID       riid,
  [out] IUnknown     **ppunk
);

Parameters

ec [in]

Edit cookie obtained from ITfDocumentMgr::CreateContext or ITfEditSession::DoEditSession.

rguidService [in]

Identifier that specifies how the embedded content is obtained.

Value	Meaning
GUID_TS_SERVICE_ACCESSIBLE	Output should be an Accessible object.
GUID_TS_SERVICE_ACTIVEX	Caller requires a direct pointer to the object that supports the interface specified by riid.
GUID_TS_SERVICE_DATAOBJECT	Content should be obtained as an IDataObject data transfer object, with riid being IID_IDataObject. Clients should specify this option when a copy of the content is required.
Caller-defined	Text services and context owners can define custom GUIDs.

riid [in]

UUID of the interface of the requested object.

ppunk [out]

Pointer to the object. It can be cast to match riid.

Return value

This method can return one of these values.

Value	Description
S_OK	The method was successful.
E_INVALIDARG	One or more parameters are invalid.
E_NOTIMPL	The implementing application does not expose embedded objects in its text stream.
TF_E_NOINTERFACE	The object does not support the requested interface.
TF_E_NOLOCK	The value in the ec parameter is an invalid cookie, or the caller does not have a read-only lock.
TF_E_NOOBJECT	The start anchor of the range is not positioned before a TF_CHAR_EMBEDDED character.
TF_E_NOSERVICE	The content cannot be returned to match rguidService.

Remarks

While the obtained object might not support certain interfaces, it is likely that the object will support those interfaces associated with embedded documents or controls such as IOleObject, IDataObject, IViewObject, IPersistStorage, IOleCache, or IDispatch. The caller must use QueryInterface to probe for any interesting interface. If the method succeeds but riid is NULL, the application indicates the presence of an embedded object but does not expose the object itself. Text processors can still benefit from a notification about the potential word break.
