You have to manually implement the IResponse interface method by method, argument by argument, in the COM Server Wizard. Not a good place for a typo! ;-). You must implement the entire interface. You can, of course, just return E_NOTIMPL for the methods you don't want to bother with - some would call that a 'quality of implementation issue'.

In the CVF COM Server wizard, there is no equivalent of VB's Implements keyword or the VC++ Implement Interface menu/functionality. Well, at least not of CVF 6.5. Don't know about 6.6. But it would be a an important feature to add.

There's the MSDN documentation for IResponse, at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/iisref/html/psdk/asp/buil27xh.asp?frame=true. How much help that is, probably depends on your experience with COM and C++. I'm sure there's plenty of other sites on the web to get related information, but almost certainly specific to a language other than Fortran.

hth,
