Get the Exchange Rates for the given Currency using X++

I did MSN search and found a public web
service; webservicex.net that provides a public currency converter web
service.
This
code snippet accesses a public web service to get the exchange rate for a given currency using x++.

static void GetExchangeRates(Args _args)

{

    com
com = new com(‘microsoft.xmlhttp’);

    com com1;

   
XMLDocument xmlDoc;

    Dialog
exchDialog = new Dialog("Exchange Rates");

   
DialogField   fromField;

   
DialogField   ToField;

   
str                 url;

    ;

   
fromField = exchDialog.addField(Types::String, ‘Base Currency’);

   
fromField.value(CompanyInfo::find().CurrencyCode);

   
ToField   =
exchDialog.addField(Types::String, ‘To Currency’);

   
if(exchDialog.run())

    {

        url = "http://www.webservicex.net/CurrencyConvertor.asmx/ConversionRate?";

        url += "FromCurrency=" +strupr(fromField.value())+"&ToCurrency="+strupr(ToField.value());       

       
com.open("get",url, false);

       
com.send();

       
com1 = com.responsexml();

        xmlDoc = XmlDocument::newXml(com1.xml());

       
info("1 "+fromField.value() + " = "
+xmlDoc.getNamedElement(‘double’).text() + " " +ToField.value());

    }

 }
