Spelling check

[VibhorG]

Hi!!!
I am making an window application in C# .NET, in which I want that when user enters any text in textbox and if there is spelling error then,the system should mark it with red line to tell the user that spelling is wrong.
Like here in forum when we type any wrong word then system automatically mark it with red line to tell user that spelling is to be corrected............
How can I add this functionality in my application for entering text in textbox...
Kindly provide me code if possible.........

There is an article you can read on adding a spell checker in a rich edit:

Read it and see if you have new insight on how you could move that over to a textBox as well :P

there is a C++ library that is open source called "aspell". you may be able to wrap it in .net get all its functionality without the headache.

but as far as I understand, on the space, comma, semicolon and period key presses, you could split the text in the box getting its last word, compare it to a dictionary and get if its spelled right. in which case you could change its color or something in a rich text box. as far as the suggestions, that could be based on a regular expression algorithm, but idk what the standard method is.

It wold be nice if the next version of .net offered a ritchtextbox control with a spellcheck feature build in.
