Creating first excel addin
 

Hi everyone,

I'm just trying to create my first Excel 2007 add-in using VS2008 and the
appropriate tools for office (I'm new to this, so please excuse trivial
questions): The thing I want to accomplish is to read/write from (and
enumerate) all the possible columns/rows in the active excel file the user
opened before - how can I do this?

Best wishes and Merry Christmas,

Peter
