IOleItemContainer::GetObjectStorage  .6N5EC

Returns a pointer to the storage for the object identified by the specified name.

HRESULT GetObjectStorage(

Parameters

pszItem

[in] Pointer 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] Pointer to the IBindCtx interface on 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 IBindCtx1JJ0LSF.

riid

[in] Reference to the identifier of the interface to be used to communicate with the object, usually IStorage.

ppvStorage

[out] When successful, indirect pointer to the location of the interface specified in riid, on the storage for the object named by pszItem. In this case, the implementation must call IUnknown::AddRef1SHW0SS on the parameter; it is the caller s responsibility to call IUnknown::ReleaseDUW01A. If an error occurs, ppvStorage is set to NULL.

Return Values

This method supports the standard return value E_OUTOFMEMORY, as well as the following:

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.

Remarks

The item moniker implementation of IMoniker::BindToStorageCA2I.L calls this method.

Notes to Implementers

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.
