I'm fairly new to Office programming; I've easily been able to develop both Smart Tags and add-ins for use in Word 2007 in VS2008 but I want to have the add-in be able to control the recognition process of the Smart Tag recognizer. I can't see any way to have my add-in communicate with my Smart Tag recognizer process. Is this feasible? Alternatively, it's not obvious to me that I can implement the Smart Tag process in the add-in (not using VSTO, since I know that doesn't support application-level Smart Tags yet, but manually using Smart Tag interfaces). Thanks Greg
