Developing XLLs in Excel 2007

Back in January I talked about updates we have made to XLLs.  We will soon be publishing an extensive article on MSDN which will cover Excel 2007 features that affect XLL add-ins and enable new XLL functionality, as well as changes to the XLL C API itself.  The article was written by Steve Dalton (author of Excel Add-in Development in C/C++: Applications in Finance).

Today I’d like to give you a preview of this very useful document – you can find the document on MSDN here.  Also, if you want to experiment with XLLs in the most recent beta, it will be useful to have xlcall.h and xlcall32.lib … send me an email using the “email†link on the top left of the page if you would like me to send you a copy of these files.
