Error while passing parameters to a web Service thorugh C++ code

[Reshma Prabhu]

Hello,

I have created an web service in C# and accessing it thrugh C++ code.
But when i make a call through the client, the parameter does not reach the
server but it does not show any error code on client.

I have attached my code with this

Connector.CreateInstance(__uuidof(HttpConnector30) );
Connector->Property["EndPointURL"] = [WEbServiceURLname]
HRESULT hr = Connector->Connect();

// Begin message
Connector->Property["SoapAction"] = "http://tempuri.org/GetFloors";
hr =Connector->BeginMessage();

// Create the SoapSerializer
Serializer.CreateInstance(__uuidof(SoapSerializer3 0));

// Connect the serializer to the input stream of the connector
Serializer->Init(_variant_t((IUnknown*)Connector->InputStream));

// Build the SOAP Message
hr= Serializer->StartEnvelope("","NONE","");
hr = Serializer->StartBody("NONE");
hr = Serializer->StartElement("GetFloors","","NONE","");

hr = Serializer->StartElement("siteId","","NONE","");
Serializer->WriteString("1");
hr = Serializer->EndElement();

hr = Serializer->EndElement();
hr = Serializer->EndBody();
hr = Serializer->EndEnvelope();

// Send the message to the web service
hr = Connector->EndMessage();

// Let us read the response
hr = Reader.CreateInstance(__uuidof(SoapReader30));
// Connect the reader to the output stream of the connector
hr = Reader->Load(_variant_t((IUnknown*)Connector->OutputStream), "");

// Display the result
MSXML2::IXMLDOMElementPtr ptr = Reader->RpcResult->get_xml((BSTR*)&bstrXml);

But the value, which is coming in bstrXml is
<faultCode>soap:Server</faultCode>

The code on server is

C#:

[WebMethod]
public string GetFloors( string siteId )
{
return "tempString";
}

Please help

It looks like you are using SOAP Toolkit. Just FYI, it is deprecated and
after March 31, 2005 it is not supported. Take a look on some migration
guides here
http://msdn.microsoft.com/webservice...kmigration.asp.

As for your error, the problem seems to be that you are not defining
namespace for your web service. Just type http://tempuri.org/GetFloors in
IE, and it will give you an error page with explanation of what to do about
it.
If you are using VS2003, please take a look on this section of documentation
http://msdn.microsoft.com/library/de...anagedcode.asp.
It has some good walkthroughs and samples of both web service providers and
consumers.
As for C++ story, in native code the best solution for web service client is
to use ATL Server. For example, you may take a look on SOAP Transport sample
http://msdn.microsoft.com/library/de...portsample.asp
It contains both a very simple web service and a very simple client for it.
As for managed code built with C++, the story is pretty much the same as for
C# or VB. If you use IDE, you need to add web reference to web service into
your project and then use a proxy class created for you by the IDE.

Hope that helps.

i've had some problems with that route that i'd like to solve. see my
