Spell Checker for CRichEditCtrl

Does anybody know where I can get a good spell checker that can be easily incorporated with a CRichEditCtrl in my app?

Thanks

Hi.

This is just my idea.

1) Use CheckSpelling function from Word or Excel Automation.
In this case, each word or whole sentence copy to Excel or Word
and these spell checker works. After this, if this spell checker
find the mistake and correct it, the word copies to your program.
Word or Excel must launch at the background when you try to check the spell.

2)Create Apps That Are Easily Extensible with Our Smart "Snap-Ins" Methodology - Microsoft System Journal 1997

This introduces COM interface to enhace our program to be competitive
with the other application.
When you search by spellcheck in MSDN help, you will find this article.

Hope for help.
