Jom – That’s bizarre. Was it Excel 2003 or 2007 that experienced the error?

It tells me that .xla is not a valid filetype for excel. I can’t remember the rest of the error message or the number, since it is not my computer that it happens on, I can’t duplicate it at this time.

Jim – What does “doesn’t recognize the file type” mean? Can you describe the symptoms? Also, what is the error message (and not just the error number)?

Hi Jon, I had an excel guru from work develop a macro file that I add in to co-workers computers. Some of them have Excel 2007 and some have Excel 2003. The macro was created in Excel 2003. He used coding for both versions to make the macro work. I am having one problem with one computer where when trying to use the Tools Add-Ins dialogue box, it won’t recognize the .xla file type and gives me an error. What could be the problem with this one computer?

You need to insert a class module into the add-in, and declare an Excel Application variable with events. In the class module you can then add events like workbook_beforesave. Before using the class you have to instantiate the application variable. This topic is covered in the "Application Events In An New Class Module" section of Chip Pearson's Application Events page.

Hi,
How can I intercept from Add-In build in event- like FileSave, so I can trigger some custom handling for that event every time for any excel workbook opened

Thanks,

Hi Rich -

There are two steps. First, the procedures are declared as Public Subs or Functions. Second, in the VB project that accesses these procedures, I have set a reference to the add-in containing the procedures: VB Editor’s Tools menu > References. This is where having a unique project name is helpful, so you can recognize your add-in in the list. Otherwise you will see a handful of items names VBProject.
