Some quick notes on updating OneNote 2007 addins for OneNote 2010

  • Article

I was asked how to do this and wrote up some "down and dirty" notes on what I found works well.

Assuming you have a toolbar based addin, here's the steps to get it working for OneNote 2010 (and only on OneNote 2010):

Find and replace “2007” strings in schema namespaces to “2010”

Delete the ON 12 COM reference

Add the ON 14 COM reference (set NOPIA if using VS2010 - https://blogs.msdn.com/b/descapa/archive/2010/04/27/onenote-2010-and-visual-studio-2010-compatibility-issues.aspx)

---these next 2 steps only apply if you created an addin that uses a toolbar icon to be invoked---

Change your GUID to be unique so that you don’t stomp on 12 addins

And lastly, change the OnEvent handler to this:

        bool OnEvent([In] OneNote.IOneNoteEvents evt, [In] String strParameter);

 

 

Do NOT:

Change the registry settings for the toolbar info from the 12.0 branch

Change the COM Import GUID [ComImport, Guid("C9590FA7-2132-47fb-9A78-AF0BF19AF4E6")]

We're working on getting the OneNote 2010 documentation finished, but if you have older code you want to see working with OneNote 2010, this may get you going for now.
