Web Service always fails when called

[Jeova Almeida]

Hello,

I'm trying to use a web service from my MFC C++ app.

For testing purposes, I created the simple web service in VS2005:

[WebMethod]
public int Sum(int num1, int num2)
{
return (num1+num2);
}

I tested it firstly using asp.net and it worked fine. To make this test, so
I could add a web reference, I
created a web site in IIS for the web service so I could test using
http://localhost/webservice/WSTest.asmx

Following that, I created a win32 console app, added a web reference to the
above
URL (which showed my Sum() method) and coded:

int _tmain(int argc, _TCHAR* argv[])

{

if(SUCCEEDED(CoInitialize(NULL)))

{

WSTest::CWSTest obj;

HRESULT hr;

int result=0;

hr = obj.Sum(3,4,&result);

if (SUCCEEDED(hr))

cout << "result = " << result;

else

cout << "error";

return 0;

CoUninitialize();

}

The problem is the call to obj.Sum() never succeeds (hr = E_FAIL). When I
created the console app, I selected ATL support, but I'm not sure if it's
needed.

What am I doing wrong?
