I created an login application its working fine but have some errors in passwords authenticating,
in DB it contains username is 'ask' and password is 'ask', when entering this information the application is logged in.
error is when user entering his username and password as 'ask' 'ask' its logged in & if the user enters the password as "ASK"(in uppercase) also its accepting.
its not checking the uppercase and lowercase characters
if u know share your ideas how to solve this problem...
