   Console::WriteLine(  "Device driver services on the local computer:" );

   for each (ServiceController^ scTemp in scDevices)

Comentários

GetDevices retorna apenas os serviços de driver de dispositivo do computador local. Para recuperar os serviços ou serviços de driver que não são de dispositivos que não são drivers, chame o GetServices método. Juntos, os dois métodos fornecem acesso a todos os serviços em um computador.
