Public Sub Close ()

Exemplos

O exemplo seguinte inicia uma instância de Notepad. Depois, recupera a utilização física da memória do processo associado em intervalos de 2 segundos durante um máximo de 10 segundos. O exemplo deteta se o processo sai antes de terem passado 10 segundos. O exemplo fecha o processo se este continuar a correr após 10 segundos.

Observações

O Close método faz com que o processo pare de esperar pela saída se estivesse à espera, fecha o handle do processo e limpa propriedades específicas do processo. Close não fecha os leitores e escritores padrão de saída, entrada e erro caso estejam a ser referenciados externamente.
