Equilla Formula Language


The extension interface is not a dual interface.

If you use the C# InterfaceType attribute make sure the value is ComInterfaceType.InterfaceIsDual for the extension interface. In case you are using the MIDL-Compiler add the dual attribute to the interface declaration.


Objects: myObj( "MyExtension.MyObject" ); //causes C1061 if the extension interface is not a 'dual' interface
