I have created an Excel Add-in with VB.net in Visual Studio 2005. Currently I test my Add-in with Excel 2013, but it should also run on Excel 2007 and 2010.
When I install my Add-in and I open Excel 2013, I open a workbook (in the code) and the "ADD-INS" tab appears with the items in my menu which are activated on a mouse click. However, I must hide this workbook to add another empty workbook (I must repeat this with several open workbooks).
The problem is that even if the "ADD-INS" tab appears with the opening of others workbooks, menu items react only on the first open workbook and remains inactive for other workbooks open thereafter.
I would like that my add-in is active and operational for all workbooks (even those opened by the user). So I want to associate the menu of my add-in to the entire Excel application, not to each individual workbook. So for each workbook, the menu items must react to mouse clicks (as is currently the case with the first workbook ).
