Comentários

O SupportsInterface método permite que a instância de proxy atual implemente interfaces COM adicionais em nome do objeto de servidor que a instância atual representa. O método atual gera a interface solicitada e retorna um ponteiro para ela. Os tipos de interfaces COM que podem ser gerados por esse método dependem do tipo de proxy, que, por sua vez, pode depender do tipo de objeto de servidor que a instância de proxy atual representa.
