WebService: how to assign value to parameter

... figured out this ... would like to share, and welcome any inputs. Since the input parameter type of my web service is an object, SisteIDLookupInParam. So I have to create this object first and then assign values to its properties. TestComplete WebService Test editor has a button 'Code', which can be used to generate the code for creating the object. The followings are my code.

function Main()

{

   var myPara = new SiteIDLookupInParam();

   myPara.MarketParticipantIdentifier = "ATCO";

   myPara.CityName = "MUNDARE";

  

   var result = new SiteIDLookupResult();

   var result = WebServices.CSISServeWS.GetSiteIDLookupResult(myPara);

   Log.Message(result.Message);

   ...

}

//the following is copied from Code generation button

function SiteIDLookupInParam()

{

  var  Result;

  var  TypeFactory;

  //Get the type factory for the web service

  TypeFactory = WebServices.CSISServeWS.TypeFactory;

  Result = TypeFactory.SiteIDLookupInParam;

  return Result;

}
