Frazer,
I am not sure what you are trying to do. The example you give deals
with showing a movie, and yet, you want the spell checker from word? If you
want to access Word functionality, you should be able to just add a
reference to the Word object library, and then access what you wish. In
this case, I would imagine the spell checker capability is something that
the Document object exposes.
Hope this helps.
