IOleItemContainer::GetObjectStorage
Returns a pointer to the storage for the object identified by the specified
name.
HRESULT GetObjectStorage(
LPOLESTR pszItem,
| //Name of the object whose storage is requested
| IBindCtx *pbc,
| //Bind context to be used
| REFIID riid,
| //IID of interface pointer desired
| void **ppvStorage
| //Receives interface pointer
| );
|
|
Parameters
pszItem
[in] Points to a zero-terminated string containing the compound document's
name for the object whose storage is requested. For Win32 applications, the LPOLESTR type indicates a wide character string (two bytes per character); otherwise,
the string has one byte per character.
pbc
[in] Points to the bind context to be used in this binding operation. The bind
context caches objects bound during the binding process, contains parameters
that apply to all operations using the bind context, and provides the means by
which the binding implementation should retrieve information about its
environment. For more information, see IBindCtx.
riid
[in] Identifies the type of interface pointer requested.
ppvStorage
[out] Receives a pointer to the storage of the object named by pszItem. If an error occurs, the implementation sets *ppvStorage to NULL. If *ppvStorage is non-NULL, the implementation must call IUnknown::AddRef on the parameter; it is the caller's responsibility to call IUnknown::Release.
Return Values
S_OK
The storage of the specified object was successfully returned.
MK_E_NOOBJECT
The parameter pszItem does not identify a object in this container.
MK_E_NOSTORAGE
The object does not have its own independent storage.
E_NOINTERFACE
The requested interface is not available.
E_OUTOFMEMORY
Insufficient memory.
Comments
The item moniker implementation of IMoniker::GetObjectStorage calls this method.
Notes to Implementors
If pszItem designates a pseudo-object, your implementation should return MK_E_NOSTORAGE,
because pseudo-objects do not have their own independent storage. If pszItem designates an embedded object, or a portion of the document that has its own
storage, your implementation should return the specified interface pointer on
the appropriate storage object.
