IWMSIPList::get_Item

The get_Item method retrieves a specific IWMSIPEntry interface from the IWMSIPList collection.

Syntax

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

Parameters

varIndex

[in] VARIANT containing the index of the IWMSIPEntry interface.

pVal

[out] Pointer to a pointer to an IWMSIPEntry interface. This method calls AddRef internally. To avoid memory leaks, you must call Release when you are finished using the interface.

Return Values

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.
