Is there a way I can protect a windows form with a password that is NOT HARD CODED! and does not depend to much on a file??? what I mean is that if somone deleted the file the program would still work. I kinda need some code here.

Guess that would depend what is too much. First, passwords should never, ever, be hard-coded in your application. There are a number of ways to do this. Use Windows authentication, use a database, hash the password initially and compare one that is given.

You could store it in some obscure place in the registry.

That will not work because my program is supposed to be portable on your flash drive. HELP!

You can use your hardware models too as a password and for matching it you can use WMI. Anyhow Hashing and Windows Authentication are good options.

Just store a hash of the password in some string in the program, re-hash the password that the user gives you, and compare it to the stored hash.
Note that a determined hacker will probably break this in seconds (by jumping over your validation code).
