SYMPTOMS
If you use the Microsoft Foundation Classes (MFC) Add Class from TypeLib wizard in Microsoft Visual Studio .NET to add a wrapper class for a Component Object Model (COM) interface, and the interface contains a method with the same name as a Microsoft Windows application programming interface (API), you may receive a compile-time error message such as the following when you compile the project:
CAUSE
The Add Class from TypeLib Wizard fails to recognize that the COM interface for which it generates a wrapper class contains methods whose names conflict with existing macro names for Windows APIs.
RESOLUTION
To work around the problem, locate the line that is specified in the error message and add an underscore (_) to the method name that is causing the conflict, then save the file and recompile the project.
STATUS
Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.
MORE INFORMATION
Previous versions of MFC correctly recognized this condition and appended an underscore (_) to the method name in the wrapper class, avoiding the name conflict while maintaining the functionality of the wrapper class.
