XLL update

David Gainer was kind enough to answer the mulit thread .xll question

Excel 97 does not support multi-threading. I can see what I wrote was confusing. What I meant was that if you had some XLLs that you have been using for some versions that you want to participate in mult-threaded calc, you can recompile them after adding the flag and they will work you don’t need to update anything to use the Excel12 API. Is that clearer?

If you’ve not seen Dave’s blog check it out, Dave keeps it updated and replys to many of the comments, very good work!

Differences between these two types of Add-ins.

Excel 97, supports multi-threading??????????

I’m not really up to speed with c programing etc, although it is somthing i’m gonna start to look at. Anyway, i dont understand this, from David Gainer Excel 12 blog

Note, the Excel4 API will also respond appropriately to the “$” character, so if an XLL author wants to take advantage of multi-threading, but doesn’t care about the big grid, they do not have to use the Excel12 API.

So does this mean that if i have a xll on my pc now, i can add “$” to it and as i stand here excel will multi thread it????

surly not?
