IWMSAccessControlList::get_Item

The get_Item method retrieves a specific IWMSAccessControlEntryIWMSAccessControlEntry Interface from the IWMSAccessControlList collection.

HRESULT get_Item(
  const VARIANT  varIndex,
  IWMSAccessControlEntry**  pVal
);

Arguments

varIndex	[in] VARIANT containing the index of the access control entry to remove.
pVal	[out] Pointer to a pointer to an IWMSAccessControlEntry interface. This method calls AddRef internally. To avoid memory leaks, you must call Release when you are finished using the interface.

Return Value

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.

Return code	Number	Description
DISP_E_BADINDEX	0x8002000B	The index contained in varIndex is not valid.
E_POINTER	0x80004003	The pVal parameter is NULL.
