Building an Excel Add-in

Posted on by jkpieterse

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!

Recent Update of Office causes problems with ActiveX controls

Posted on by jkpieterse

Hi,

Yesterday, I installed a host of updates, including some of Office.
As it happens, I tried to add an ActiveX control to a worksheet and received an error.
After some research I discovered the cause of the error to be two-fold:

1. The controls were updated by the update
2. Excel did not clean up after itself properly and left some temporary files behind.

The solution is to:
– Quit Excel
– Open Explorer
– Select C: drive
– Search for *.exd
– Remove all files found.

Hope this helps other people who might be suffering from the same problem.

#####UPDATE Dec 22, 2014#####
Microsoft has published a so-called Fixit to make resolving this matter easier:

A VBA performance class

Posted on by jkpieterse

Hi everyone!

If you write a lot of VBA code you probably sometimes run into performance issues. A customer rings you and complains that the Excel file you built for them does not perform well. I’ve written a small article on my site, inspired by a post here: Error Handling via an Error Class. I needed a quick way to log and report performance of subroutines and I also wanted to see how many times a routine was called.

See: A VBA performance class

Enjoy!
