On pages 178 and 179 the authors have examples calling web services directly from a client side AJAX call using webservice.htc in the Internet Explorer approach.

I downloaded the .htc from the MSDN site and added it to my project root.

------------------------------------------------------
In my page I am calling 2 different web services.
------------------------------------------------------
1). To update one specific value with one web service.
2). To update another specific value with another web service.

Scenario #1 works fine.

However, when I call scenario #2, I get an error when calling a second method I wrote, analagous to the performSpecificOperation(p1,p2,p3) on the top of page 178.

------------------------------------------------------
Here's the oResult object contents:
------------------------------------------------------
oResult.id=2
oResult.error=true

oResult.errorDetail.code="Client"
oResult.errorDetail.string="Invalid argument"
oResult.errorDetail.raw=null

------------------------------------------------------
Here's my version of the performSpecificOperation method:
------------------------------------------------------
function updatePriority()
{

  var convHandle = document.all.txtConHandle.value;
  var sMethod = "UpdateStudiesPriority";
  var selIndex = document.all.cboPriority.selectedIndex;
  var updateVal = document.all.cboPriority[selIndex].value;


  var oServiceHandler = document.getElementById('divServiceHandler');

  if(! oServiceHandler.QManagerWebService)
  {
    oServiceHandler.useService(mServiceUrl + " WSDL", "QManagerWebService");
  }
try
  {
    mICallID = oServiceHandler.QManagerWebService.callService(han dleResponseFromBehavior, sMethod, convHandle, updateVal);
  }
    catch(err)
    {
      alert(err);
    }

}


Not sure what I'm doing wrong..

Thanks..

Never mind.

I forgot to put a [WebMethod(Description = "")]
directive above the web method..
