I tried the c++ code from he
http://support.microsoft.com/?id=327215
loaded it in MS VC6++ and compiled it to a dll with no errors.
Haven't tried to use it yet with Excel, but it looks promising.

I am looking for a third party that produces an interface that allows
programming, etc for developing a RTD Server add-in for Excel 2007. Has
anyone used any third party tools in the development of RTD add-ins for
Excel? If so, what is the name or website of the third party vendor? I
have
been searching but it is difficult to evalutate just from reading the info
on
the website. I do realize that an add-in can be done using visual studio
and
visual basic, but I also needed to explore the option of a third party
vendor
that already has the architecture already built in.
Thanks for any response and info.
