Re: GetExtension not working

[User (Legacy)]

Hey Andrew, 

I tried your code exactly in my app and it works okay (pops up annotation 

tool bar and returns pAnnList as something other than NULL)...  sorry- i 

know thats no help to you except to say you're doing it right...  is there 

any chance you dont have the latest versions of chartfx?
