Good day, boraka, it is not a good idea to post an seemingly endless list of code (somewhere around 400 lines?), especially without putting it into the nice code boxes provided.. people can hardly get to the Reply button ;) Read the forum FAQ http://www.vbdotnetforums.com/faq.php about to posting tools at your disposal. Also provide meaningful thread titles, I changed "İ need help please" to "save keyboard characters please"

couldn't you just handle the OnKeyPress event on the form and capture the character and append that character to your file stream? If you're filestream is the problem, write the character into a stringbuilder and once the stringbuilder reaches a certain pre-defined limit, flush the stringbuilder to your filestream.
