Spell Checking from Delphi code using MS Word - Office Automation in Delphi

As a bonus the project has the code to use Word's Thesaurus. Using the thesaurus is quite easier. We don't parse the text, for the selected word the CheckSynonyms method is called. This method displays its own selection dialog. Once a new word is selected, the Word Documents Range contents is used to replace the original word.

Download the project's code and add spell checking to your applications.
