Exempel

I följande kodexempel visas hur du öppnar en registernyckel på en fjärrdator och räknar upp nyckelns värden. Fjärrdatorn måste köra fjärrregistertjänsten. Ange namnet på fjärrdatorn som ett kommandoradsargument när programmet anropas.

Kommentarer

RegistryHive värden används av OpenRemoteBaseKey metoden för att representera noden på den översta nivån för en begärd nyckel på en sekundär dator (fjärrdator). Noden som kan öppnas med metoden OpenRemoteBaseKey måste vara en av dessa toppnivå RegistryKeys. Ytterligare åtkomst till undernycklarna för den identifierade noden är tillgänglig med hjälp av metoder i RegistryKey, så länge användaren har rätt behörighet.
