I just started an application that change the attributes of the word entered in the richedit according to word level (i.e. level 1 dog, cat, apple - simple words). It is a live checker it means it would check everytime a character is entered. I got how to do this using selstart and sellength but the problem is whenever I entered character(s) it would flicked obviously from the selstart and sellength. Anyway I'm using AddictSpell3's richedit so that my application has an spell check feature. Does AddictSpell's richedit use selstart and sellength to put a distorted line below the wrongly spelled word?
