Syntax
HRESULT QueryId(
LPWSTR* Id
);
Parameters
- ID
Identificador PIN.

Remarks
Essa função membro implementa o IPin::QueryId método. Ele substitui o CBasePin::QueryId função membro e atribui a seqüência de caracteres "em" Para ID. Observe que ele usa o Win32 CoTaskMemAlloc função ao inicializar ID, portanto, o usuário é responsável por liberando o bloco formato usando CoTaskMemFree.
