Thanks, its help, but now i have little bit different issue. I have textbox, where maxlenght = 14 and i need that when this textbox contain string with lenght 14 then data will be saved in database otherwise textbox will be clean. Data will be added by scanner. I tried len function under TextBox1_TextChanged, tried TextBox1.TextLength but nothing is good. I want to avoid timer which will check this textbox every second, dont want any button to execute function. BTW this textbox should contain specific string which i already have in database, i know that this string begins with specific prefix (5 letters), maybe this can be used.
Thank you guys
