Hour 12

1:
How does an ATL Web Service expose its methods?

A1:
It declares an interface that is then implemented by a class.

2:
What type of method do you create in the ATL class to support the Web Service calls?

A2:
You declare a method with the [soap_method] attribute to indicate that the method uses SOAP for communication.

3:
What is the return type for all exposed ATL Web Service methods?

A3:
HRESULT

4:
How do you specify the return value that is returned to the Web Service user?

A4:
By declaring the last parameter with the [out, retval] attribute.

5:
What limitation does the return value type have for an ATL Web Service method?

A5:
Each return value must be declared as a pointer to a type. You cannot directly return a value.
