IStorage::DestroyElement (Windows Embedded CE 6.0)

1/6/2010

This method removes the specified storage or stream object from this storage object.

Syntax

HRESULT DestroyElement( 
  WCHAR* pwcsName 
);

Parameters

  • pwcsName
    [in] Pointer to a wide character string that contains the name of the storage or stream to be removed.

Return Value

The following table shows the return values for this method.

Value Description

S_OK

The element was successfully removed.

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 caller does not have sufficient permissions for removing the element.

STG_E_FILENOTFOUND

The element with the specified name does not exist.

STG_E_INSUFFICIENTMEMORY

The element was not removed due to a lack of memory.

STG_E_INVALIDNAME

Invalid value for pwcsName.

STG_E_INVALIDPOINTER

The pointer specified for the element 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 element was not removed because there are too many open files.

Remarks

The DestroyElement method deletes a substorage or stream from the current storage object. After a successful call to DestroyElement, any open instance of the destroyed element from the parent storage becomes invalid.

If a storage object is opened in transacted mode, destruction of an element requires that the call to DestroyElement be followed by a call to the IStorage::Commit method.

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

Requirements

Header objidl.h, objidl.idl
Library ole32.lib, uuid.lib
Windows Embedded CE Windows CE 2.0 and later
