Hi,


I wish to add an RTD server for Excel to an existing C++ application
(using
Visual Studio 6). So far I have figured out that I need COM, and the
iRtdServer class. I think I have more or less figured out the COM thing,
but
I still need the elusive iRtdServer class. I would appreciate it if
someone
could help me with some pointers on where to find the class, or perhaps
even
a (C++) code example showing how to implement the entire server.


Thanks in advance,

Hans Guijt
