Default Hiding Methods in Automation Add-In
Hi Matthew,

Check that the public interface is marked as
ComInterfaceType.InterfaceIsDual or at least
ComInterfaceType.InterfaceIsDispatch (with the [InterfaceType] attribute).

In VS 2005 and Excel 2003. I am writing an Automation Add-In in C# and
don't
want to expose the Object methods (GetHashCode, GetType etc.) to end users
to
put in their cell formulas. A post he
http://groups.google.com/group/micro...6a59ead000e62?

suggests marking the class as ClassInterfaceType.None and implementing a
public interface with just the desired methods but this does not work
(maybe
it worked in .NET 1.1). Help?
