Hi all,

Does anyone know how to get SDK for programming Excel add-ins?
I found something from MSDN, but it does not work well (seems to be very
old, no html page, but just a directly link to the file). I know VC++ (not
familiar with COM), but following online tutorial or MSDN like:

does not work well (can't compile).

Can anyone help?
Thank a lot.
