How to add Spell check in any Windows application?

TinySpell is a small utility that provides a spell checking like functionality in any windows applications. This utility is useful, especially with Notepad or web browser where typing is occasionally needed.

TinySpell (freeware) can watch your typing on the fly and alert you whenever it detects a misspelled word. It can also check the spelling of text you copy to the clipboard.

After installation you’ll see a small icon in the system tray. Normally the icon is white but it turns to yellow when a misspelled word is detected. Clicking the yellow tinySpell icon, or pressing the hot-key (Ctrl+;), pops up a list of suggested replacement words from which you can select a correction.

You can set tinySpell to insert the selected word into your document or copy it to the clipboard (or both). tinySpell comes with an American-English dictionary containing more than 110,000 words.
