Spell Checker

[HaimK]

I have found a very good .net spell checking component which works flawlessly with the textcontrol with very little additional programming effort. It is the rapidspell spell checker available at www.keyoti.com (http://www.keyoti.com).

All one needs to do is to wrap the text control in a class which implements their spell checking interface. This class can then be used transparently with the spell checker with no other special programming.

You might need to ask them specifically for the textcontrol compatible version as I don't know if the necessary interface is included in their public evaluation version.

Here is what the wrapper class looks like in C#. I also have a vb version if anyone is interested.
