I'm trying to create an add-in, that allows users to open excel workbooks or templates and can't seem to find a way to do that.

Any ideas?

So my apologies if this shows up twice got an error when I first tried to reply.

Your question doesn't have enough context for me to be certain I'm giving you a valid answer. An add-in loads whenever the application loads so I'm not sure what your goal is if you load word to have an add in to open a Word doc (as opposed to the existing Open...)

Having said that you're probably going to want to leverage the Office COM layer to call the open. I don't recall the exact call off teh top of my head but basically you want to pass the document name (full path) to the object layer to have Word or Excel load the appropriate document.

Hope this helps,
Bill

Hi Bill -

More context. I have 2 VSTO applications. One is an Excel Add-In, the other is an Excel workbook project, with a task pane.

Ideally what I'd like to have happen is the user installs the add-in, opens excel, and from my add-in ribbon, they are able to open the workbook referenced in my workbook project, which would have the task pane.

VSTO has an easy open workbook method, but that won't work on a VSTO workbook project.
