We're not here to do your homework for you. If you want help, you'll have to make an honest attempt at solving the problem and then ask a specific question.

4.Login name and password are hardcoded in the program and not strored in any file.

I find this self-contradictory. "Hardcoded" means that password WILL BE stored in program file as embedded string resource. So for added security i suggest to hardcode not plain password, but instead MD5 hash of password. And when user enters password - you will do check md5(password)== hardcoded_md5_of_password .
Point is that if something will extract password hash from the executable file - he/she will not find-out password, because md5 hash is one way encryption. (Unless he/she does bruteforce,- generates all possible passwords and compares it's hash with stored one).
In any case a way of storing md5 hash is a LOT more secure than storing just plain password.
p.s.
google MD5,- there a a lot of md5 implementations in C.
good luck

This is a very old thread from 2009.

If you have a current problem like this, please start a new thread, and don't add to this one.

The "zombie's" need their rest. ;)
