Keyoti RapidSpell Desktop .NET is a must if you want to easily add spellchecking capabilities to your programs. It took me less than a day (!) to learn how to use it and to include it, with all features you expect to have, with my latest project. Since I use a lot of RichText fields with large text-blocks I was a bit afraid that the spellchecking while typing would make my program sluggish – but no, even on a slow computer the extra spellchecking can hardly be measured, and since the component uses threads it never interferes while the user does extensive work. I am impressed! Since we target the Scandinavian market I needed some new dictionaries (Swedish, Finnish, Norwegian and Danish). I thought this would give me problems, but after a quick look on the Internet I found several very good wordlists which can be used royalty free. I simply loaded these lists into the included dictionary manager and I now have all the dictionaries I need! Special customer adapted dictionaries can therefore easily be created – adds a nice touch to my projects' feature-lists… Keyoti’s support seems to match the quality of their products. I use the Infragistics NetAdvantage user interface components and needed a new build to match their latest version – it took not long before Keyoti sent me what I needed. Finally, the price and licensing (run-time royalty free) makes the component a bargain. Even if you do not use a lot of text-components in your programs I really recommend you to add RapidSpell. It is cheap, so easy to learn, no noticeable performance hit, and gives your projects a solid professional look.
