Hello, When I export an IDL class (via COM) using the Export Bridge Assistant, it seems to be bound to the specific version of IDL that I used to create the exported dll. So when a new version of IDL comes out and I want to upgrade my applications, I need to rebuild my COM export bridge dll using the newer version and recompile my client applications. Does anyone know an alternative or more convenient way to get these export bridge dlls to work with newer versions of IDL, without having to rebuild older components? Many thanks, Simon
