spell checker
HI there,
I am working a spell checker GUI program and I am kinda stuck on search for a word and replacing.
I imported a file with all the words.
the fuctions of the programs is as follows
as i type in the text area if there is a misspelled which is smilar to the one from the imported file then it should highlight or underline and then when i go to tools and check for spelling ti should suggest similar words and i should be able to replace or ignore the word or ignore all...
well to sum up i need a spell check just like in ms word
here is my code...
plz help me out...
