    // The Chilkat API can be unlocked for a fully-functional 30-day trial by passing any
    // string to the UnlockBundle method.  A program can unlock once at the start. Once unlocked,
    // all subsequently instantiated objects are created in the unlocked state. 
    // 
    // After licensing Chilkat, replace the "Anything for 30-day trial" with the purchased unlock code.
    // To verify the purchased unlock code was recognized, examine the contents of the LastErrorText
    // property after unlocking.  For example:
    CkGlobal glob;
    bool success = glob.UnlockBundle("Anything for 30-day trial");
    if (success != true) {
        strOut.append(glob.lastErrorText());
        strOut.append("\r\n");
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    int status = glob.get_UnlockStatus();
    if (status == 2) {
        strOut.append("Unlocked using purchased unlock code.");
        strOut.append("\r\n");
    }
    else {
        strOut.append("Unlocked in trial mode.");
        strOut.append("\r\n");
    }

    // The LastErrorText can be examined in the success case to see if it was unlocked in
    // trial more, or with a purchased unlock code.
    strOut.append(glob.lastErrorText());
    strOut.append("\r\n");
