Add new words to dictionary file using infragistics spell checker

[swathichiran]

My task is to add new words to dictionary file.
so am using infragistics webspell checker control. With out creating virtual directory to application, i could add new words to dictionary file. But if the virtual directory is created, even though i click on add, new words are not included to dictionary file. Then i understood it to be a permission problem and added "ASPNET/Network Service" user and given write permission to that user. Now i could add words to dictionary file.
But my requirement is to add new words with out giving any write permission.
