void ChilkatSample(void)
    {
    CkString strOut;

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

    // The signed XML to be verified in this example contains the following:

    // <?xml version="1.0" encoding="ISO-8859-1"?>
    // <DTE version="1.0" xmlns="http://www.sii.cl/SiiDte">
    // <Documento ID="F13T34">
    // ...
    // </Documento>
    // <Signature xmlns="http://www.w3.org/2000/09/xmldsig#">
    // ....
    // </Signature>
    // </DTE>

    // Load the signed XML into sbXml -- telling Chilkat to interpret the bytes as iso-8859-1 
    CkStringBuilder sbXml;
    bool success = sbXml.LoadFile("qa_data/xml_dsig/sii_cl/signed1.xml","iso-8859-1");
    if (success == false) {
        strOut.append("Failed to load input file.");
        strOut.append("\r\n");
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    CkXmlDSig dsig;

    success = dsig.LoadSignatureSb(sbXml);

        strOut.append("\r\n");
        SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
        return;
    }

    bool bVerifyReferenceDigests = true;
    bool bVerified = dsig.VerifySignature(bVerifyReferenceDigests);
