    //  Also see Chilkat's Online WSDL Code Generator
    //  to generate code and SOAP Request and Response XML for each operation in a WSDL.

    //  This example uses a live web service at:
    //  http://www.webservicex.net/uklocation.asmx
    //  It gets the UK town,Postcode and County by Postcode(First Section of Post Code)

    //  The SOAP XML will look like this:
    //  <?xml version="1.0" encoding="utf-8"?>
    //  <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    //    <soap:Body>
    //      <GetUKLocationByPostCode xmlns="http://www.webserviceX.NET">
    //        <PostCode>string</PostCode>
    //      </GetUKLocationByPostCode>
    //    </soap:Body>
    //  </soap:Envelope>

    //  For this example's sake, we'll load the XML from a file.  We'll test using PostCode "E3".  
    //  The SOAP XML for this example may be downloaded from:
    //  http://www.chilkatsoft.com/testData/ukPostCodeSoap.xml
    xml = CkXmlW_Create();
    success = CkXmlW_LoadXmlFile(xml,L"ukPostCodeSoap.xml");
    if (success == FALSE) {
        wprintf(L"%s\n",CkXmlW_lastErrorText(xml));
        CkXmlW_Dispose(xml);
        return;
    }

    strXml = CkXmlW_getXml(xml);

    http = CkHttpW_Create();

    //  We'll need to add this in the HTTP header:
    //  SOAPAction: "http://www.webserviceX.NET/GetUKLocationByPostCode"
    CkHttpW_SetRequestHeader(http,L"SOAPAction",L"http://www.webserviceX.NET/GetUKLocationByPostCode");

    //  The endpoint for this soap service is:
    endPoint = L"http://www.webservicex.net/uklocation.asmx";

    //  Note: This particular web service was live and functioning at the time this example
    //  was written.  It is possible that as time progresses, this web service will no longer
    //  be availble...
    resp = CkHttpResponseW_Create();
    success = CkHttpW_HttpStr(http,L"POST",endPoint,strXml,L"utf-8",L"text/xml",resp);
    if (success == FALSE) {
        wprintf(L"%s\n",CkHttpW_lastErrorText(http));
        CkXmlW_Dispose(xml);
        CkHttpW_Dispose(http);
        CkHttpResponseW_Dispose(resp);
        return;
    }

    responseStatusCode = CkHttpResponseW_getStatusCode(resp);
    //  You may wish to verify that the responseStatusCode equals 200...
    wprintf(L"Response Status Code: %d\n",responseStatusCode);

    //  You may examine the exact HTTP header sent with the POST like this:
    wprintf(L"LastHeader:\n");
    wprintf(L"%s\n",CkHttpW_lastHeader(http));

    //  Examine the XML returned by the web service:
    wprintf(L"XML Response:\n");
    xmlResp = CkXmlW_Create();
    CkXmlW_LoadXml(xmlResp,CkHttpResponseW_bodyStr(resp));
    wprintf(L"%s\n",CkXmlW_getXml(xmlResp));
