Voorbeelden

In het volgende codevoorbeeld ziet u hoe u een registersleutel op een externe computer opent en de waarden van de sleutel opsommen. De externe computer moet de externe registerservice uitvoeren. Geef de naam van de externe computer op als een opdrachtregelargument bij het aanroepen van het programma.

using namespace System;
using namespace System::IO;
using namespace System::Security::Permissions;
using namespace Microsoft::Win32;


int main( int argc, char *argv[] )
{
   RegistryKey ^ environmentKey;
   
   // Check that an argument was specified when the 
   // program was invoked.
   if ( argc == 1 )
   {
      Console::WriteLine( "Error: The name of the remote computer "
      "must be specified as input on the command line." );
      return  -1;
   }

   try
   {
      
      // Open HKEY_CURRENT_USER\Environment on a remote computer.
      environmentKey = RegistryKey::OpenRemoteBaseKey( RegistryHive::CurrentUser, gcnew String(argv[ 1 ]) )->OpenSubKey( "Environment" );
   }
   catch ( IOException^ e ) 
   {
      Console::WriteLine(  "{0}: {1}", e->GetType()->Name, e->Message );
      return  -1;
   }

   
   // Print the values.
   Console::WriteLine( "\nThere are {0} values for {1}.", environmentKey->ValueCount.ToString(), environmentKey->Name );
   array<String^>^valueNames = environmentKey->GetValueNames();
   for ( int i = 0; i < environmentKey->ValueCount; i++ )
   {
      Console::WriteLine(  "{0,-20}: {1}", valueNames[ i ], environmentKey->GetValue( valueNames[ i ] )->ToString() );

   }
   
   // Close the registry key.
   environmentKey->Close();
}

Opmerkingen

RegistryHive waarden worden door de OpenRemoteBaseKey methode gebruikt om het knooppunt op het hoogste niveau van een aangevraagde sleutel op een externe computer weer te geven. Het knooppunt dat kan worden geopend met de Methode OpenRemoteBaseKey, moet een van deze topniveau RegistryKeyszijn. Verdere toegang tot de subsleutels van het geïdentificeerde knooppunt is beschikbaar met behulp van methoden, RegistryKeyzolang de gebruiker over de juiste machtigingen beschikt.
