Building an Excel Add-in

Hi there!

Only recently I read this quote somewhere: “If you want something done, ask a busy person”. I found two entirely different people as the originator of this quote: Benjamin Franklin and Lucille Ball. I wonder which it is…

Well, turns out I’ve been quite busy as of late. So I decided it was time to dust off some old stuff I prepared to add to my site but never came round to finishing (I must have become less busy when I was almost done :-) ).

If you’re about to embark on the journey to create an add-in out of a set of macro’s you have been using for some time now, this article is a nice read as it takes you through most of the steps needed when building an add-in for Excel.

Enjoy!

  1. This post has inspired me to resurrect some old VB6 (!) code I used to comment my procedures, classes, and forms (a copy of the comments it would place at the top of the code segment is below). I probably have a few APIs to upgrade! I’m writing enough VBA code that I can’t remember what modules reference each other, and this code was certainly useful back in the day.

    I’d like to convert it to Excel 2013 (64-bit for the added degree of difficulty), but I have no idea how to create an add-in for the VB Editor thw way it worked in VB6.
    While my cursor is within a particular module I would like to click an icon on the VB Editor toolbar that calls up a userform where I can input my info (the section starting with “Author” below) and have the program add the rest.
    I’m happy to email the original code if you think this is worthwhile to have done by a true professional .

  2. P.S.
    The routine automatically determines the type of procedure or class your cursor is in and adjusts the searches it does accordingly. Here’s the comment it automatically generates for a function.
