* Interactive spell checking - Sentry can spell check the contents of text strings, standard text boxes, and rich-text boxes, including TEdit, CEdit, TRichEdit, and CRichEdit controls, plus TX Text Control. Misspelled words are highlighted in the text boxes as they're found, and replacements made by the user are updated instantly. * Background spell checking - Sentry even supports "as you type" or background spell checking, similar to the feature found in Microsoft Office. Misspelled words are drawn in red and changed back to black when corrected. Suggestions are shown in a context menu displayed when the mouse is right-clicked over a misspelled word. * Roll-your-own user interface - Although Sentry includes built-in user interface features, you can create your own user interface, or use Sentry in non-interactive applications such as batch processing text. * Friendly, royalty free licensing - Our license agreement permits you to distribute an unlimited number of copies of the Sentry DLL and dictionaries with your applications, without the burden of copy counting, royalties, or run-time fees. Plus no obtrusive product logos or branding requirements -- a simple copyright statement is all that's needed. * High quality dictionaries included - Sentry comes with superb 100,000-word American, British, and Canadian English dictionaries with comprehensive coverage of general words, contractions, abbreviations, and capitalized proper names. Words in the dictionary have been carefully selected to provide complete coverage of average English vocabulary and minimize spurious error reports.
