    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // Chilkat recommends the following free tool for interactively examining the contents of your smart card
    // through the ScMinidriver interface:  MGTEK Tool for Minidriver enabled Smart Cards

    // Let's first look at our smart card..
    // Here's the view of the card we happen to be using: a Gemalto (Thales) IDPrime MD T=0 smart card.

    

    CkScMinidriver scmd;

    // First we need to acquire a context to the smart card in the reader where it is inserted.
    // Reader names (smart card readers or USB tokens) can be discovered
    // via List Readers or Find Smart Cards
    const char *readerName = "Alcor Micro USB Smart Card Reader 0";
    bool success = scmd.AcquireContext(readerName);

        strOut.append(scmd.lastErrorText());

        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    // If successful, the name of the currently inserted smart card is available:
    strOut.append("Card name: ");
    strOut.append(scmd.cardName());
    strOut.append("\r\n");

    // To delete the contents of a key container, we'll need to be PIN authenticated..

    // For more details about smart card PIN authentication, see the Smart Card PIN Authentication Example
    const char *pinId = "user";
    int retval = scmd.PinAuthenticate(pinId,"0000");

    // Let's delete the contents of key container #7
    // This deletes both keys (signature key and "key exchange" key) that might be present in the key container.
    // (It is not possible to delete just one or the other.)
    success = scmd.DeleteKeyContainer(7);
