You cannot use the name of a base class by itself. This error has the following causes and solutions:
Place the base-class name within parentheses to indicate you want to access the default member.
Use a disambiguator ( for example, an exclamation point) between the base-class name and the member you are interested in.
Use the base-class name to retrieve a reference for example, using GetObject.
