Champs

DoNotExpandEnvironmentNames	1	Une valeur de type ExpandString est récupérée sans développer ses variables d'environnement incorporées.
None	0	Aucun comportement facultatif n'est spécifié.

Exemples

L’exemple de code suivant crée une clé de test, ajoute une valeur avec une variable d’environnement incorporée et récupère la valeur sous forme développée et non expirée.

#using <Microsoft.VisualBasic.dll>

using namespace System;
using namespace Microsoft::Win32;
using namespace Microsoft::VisualBasic;

int main()
{
    // Delete and recreate the test key.
    Registry::CurrentUser->DeleteSubKey( L"RegistryValueOptionsExample", false );
    RegistryKey ^ rk = 
        Registry::CurrentUser->CreateSubKey( L"RegistryValueOptionsExample" );
   
    // Add a value that contains an environment variable.
    rk->SetValue( L"ExpandValue", L"The path is %PATH%", 
        RegistryValueKind::ExpandString );
   
    // Retrieve the value, first without expanding the environment
    // variable and then expanding it.
    Console::WriteLine( L"Unexpanded: \"{0}\"", 
                        rk->GetValue( L"ExpandValue", 
                        L"No Value", 
                        RegistryValueOptions::DoNotExpandEnvironmentNames ) );
    Console::WriteLine( L"Expanded: \"{0}\"", rk->GetValue( L"ExpandValue" ) );
 
    return 0;
} //Main

Remarques

Utilisez l’indicateur DoNotExpandEnvironmentNames avec la surcharge de méthode RegistryKey.GetValue(String, Object, RegistryValueOptions) .
