DLL files for Excel

[freakalien]

I am a relative newcomer to C++ and am limited to writing console applications at the moment. I would like to write functions in C++ for use in Excel via DLL files. Could a member recommend a text (or other resource) that will assist me in learning this technique please?

Thanks
