Create COM add-in using VBA
 

Hi,
I've come across a couple of articles that show how to create a COM
add-in using VBA, but they apply to XL 2000 and there's enough of a
difference with XL 2007 that I can't re-create that same add-in. Does
anyone know how to create a COM add-in using VBA in XL 2007 or point
me in the right direction to find a solution?
Thanks.
James
