ike alot of people my maths was stronger than my english at High School, probably one of the reason I was attracted to computer programming in the first place. Even today one of my weaker points would be spelling. If you're like me fear not help is at hand from ComponentOne
IntelliSpell is an addon for Visual Studio 2008 or 2005 that will spell check your comments, strings, HTML, XML resources and general text. There is a free community edition and a Professional edition at $79.99 which offers a few more features. You get a comparison of the two editions along with download and purchase links at: http://www.componentone.com/SuperProducts/IntelliSpell/
Once you have installed IntelliSpell the spellchecker is avaliable from Visual Studio's tools menu as shown in the screenshot. With the Professional edition you get the ability to spell check an entier solution at once along with 'as-you-type spell-checking', but with the community edtion you spell check one file at time, still better than we had before. Any spelling mistakes will be shown in the task list.
