    32  *    // List all implementations.

    33  *    REComSession::ListImplementationsL( 

    34  *       KPslnSlideSetDialogUidInterface,

    36  *    CleanupResetAndDestroyPushL( array );

    37  *

    38  *    // Load screensaver implementation.

    39  *    CImplementationInformation* info = 

    40  *       array[ KPslnScreenSaverSlideSettingDialog ];

    41  *    TUid implUid = info->ImplementationUid();

    42  *

    43  *    // Instantiate plugin.

    44  *    CPslnSlidesetScreensaverDialogInterface* plugin = 

    45  *        CPslnSlidesetDialogInterface::NewL( implUid );

    46  *    CleanupStack::PushL ( plugin );

    47  *

    48  *    // Finally execute.

    49  *    plugin->ExecuteLD();

    50  *    CleanupStack::Pop( plugin );

    51  *    CleanupStack::PopAndDestroy(); // array
