Comments on: Create Your Own Excel Add-Ins http://guj800.wordpress.com/2008/06/20/create-your-own-excel-add-ins/ Musings in technology, philosophy, and all things guj Wed, 04 Nov 2009 18:12:49 +0000 http://wordpress.com/ hourly 1 By: Tom Adler http://guj800.wordpress.com/2008/06/20/create-your-own-excel-add-ins/#comment-78 Tom Adler Wed, 27 Aug 2008 17:58:42 +0000 http://guj800.wordpress.com/?p=22#comment-78 I have had some trouble with this, everything works smoothly with the CAGR forumla, I went through all the steps and got to the very last part where you click it to be an add-in. After doing so I go back to my workbook and it locks the pane. The add-in will work but the rest of the excel file is froze. Or if I get the file to unfreeze then the formula won't work. I have searched to see if there is a security setting not allowing my add-in to work but it seems that all requirements are accounted for. Please help.

If a user-defined formula (a custom formula or UDF) is held in an add-in (or in personal.xls) then it is only available to a s/sheet when the sheet is loaded on a computer that has that add-in installed, or has had that formula added to personal.xls. Other than big (usually commercially available) add-ins we keep UDFs in a module attached to the s/sheet that needs them. I prefer to put <i>operations</i> like creating / formatting charts, deleting blank rows, applying finicky formats, or sorting on > 3 sort fields either in personal.xls or in an add-in (if it is to be shared with a group). All of these actions can be performed and then will 'stand alone' - it doesn't matter if the next user has the same facility or not; the s/sheet has been chnaged in the way youi want and will stay that way. If the next user can't make the same change (really, they just can't do so as easily) then that's their problem, not yours. A couple of warnings, or at least, considerations:
