Username function

[jamie85]

Does anyone have an example of a username and password function??

THanks.

What is it that you want to do with the username and password? Do you want to search through a database to confirm the entered data or what?

At the beginning of the program i want the user to enter a username. I then would like program to compare the entry with the username that is stored in a file. If that compare == 0 then i want the program to prompt the user to enter a password and the password should also be compared with the password saved in a file.

i wrote myself something so i could see how i would do this...

******************************************

when program is first run....

enter username......save username in file

enter password.....save password in file

display menu

exit program



open program


prompt user for username.....

user enters username.....compare string with that in file if == 0 then

prompt user for password



user enters password...compare string with that in file if == 0 then

display menu
*****************************************


but this way everytime i enter the program its going to save the username and password everytime!?!?

Wrte TWO programs.

yes, i'd suggest writing two programs, or one with dual functionality somehow that would give you "admin" privileges to modify the user account settings.

if you wrote two programs, one would be the one that sets up the account, and the other would be the one that uses those accounts and wouldn't work unless you typed in the passwords
