login program

[IGI30]

I am looking to make a program which first asks user to login. like

1. Already having an account
2. Create new account

If user has already have account then it asks for username and password.
It will check username, password entered correct or not.
If username is wrong then it display

Username not found
1. Retry
2. Create new account

And if password is wrong then

Wrong password
1. Retry
2. Relogin with another username
3. Create new account

If "create new account"
then it asks to enter new username and password and save that file name same as its username in .dat format.

If possible then save that file in "My Documents" folder

I've created the program but it is not working properly.

Please help.

I've created the program but it is not working properly.

I'd suggest to change something so that it works properly
