Send Feedback

This method copies or moves a substorage or stream object from this storage object to another storage object.

HRESULT MoveElementTo( const WCHAR* pwcsName, IStorage* pstgDest, LPWSTR pwcsNewName, DWORD grfFlags );

Parameters

  • pwcsName
    [in] Pointer to a wide character string that contains the name of the element in this storage object to be moved or copied.
  • pstgDest
    [in] IStorage pointer to the destination storage object.
  • pwcsNewName
    [in] Pointer to a wide character string that contains the new name for the element in its new storage object.
  • grfFlags
    [in] Specifies whether the operation should be a move (STGMOVE_MOVE) or a copy (STGMOVE_COPY). See the STGMOVE enumeration.

Return Values

The following table shows the return values for this method.

Value Description
S_OK The storage object was successfully copied or moved.
E_PENDING Asynchronous Storage only: Part or all of the element's data is currently unavailable.

For more information see the IFillLockBytes interface and Asynchronous Storage.

STG_E_ACCESSDENIED The destination storage object is a child of the source storage object.
STG_E_FILENOTFOUND The element with the specified name does not exist.
STG_E_FILEALREADYEXISTS The specified file already exists.
STG_E_INSUFFICIENTMEMORY The copy or move was not completed due to a lack of memory.
STG_E_INVALIDFLAG The value for the grfFlags parameter is not valid.
STG_E_INVALIDNAME Invalid value for pwcsName.
STG_E_INVALIDPOINTER The pointer specified for the storage object was invalid.
STG_E_INVALIDPARAMETER One of the parameters was invalid.
STG_E_REVERTED The storage object has been invalidated by a revert operation above it in the transaction tree.
STG_E_TOOMANYOPENFILES The copy or move was not completed because there are too many open files.

Remarks

Invoking the IStorage::MoveElementTo method is typically the same as invoking the IStorage::CopyTo method on the indicated element and then removing the source element. In this case, the MoveElementTo method uses only the publicly available functions of the destination storage object to carry out the move.

If the source and destination storage objects have special knowledge about each other's implementation, they could, for example, be different instances of the same**implementation, this method can be implemented more efficiently.

Before calling this method, the element to be moved must be closed, and the destination storage must be open.

To determine whether the platform supports this interface, see Determining Supported COM APIs.

Requirements

OS Versions: Windows CE 2.0 and later.
Header: Objidl.h, Objidl.idl.
Link Library: Ole32.lib, Uuid.lib.
