Is there a way to embed a text file into an exe when it's compiled so everything's in one package, but the text file can be changed, and anyone else using the program would get the effects of the new text.

What I'm making is a messenger program, but all of the messages and user loggons are stored in 2 seperate files, which naturaly the idiot in my class constantly tries to hack and cause problems, life overloading it with text coppied and pasted, or changing his logon to an admin status. I want to put these 2 files into the program so they can be accessed every 1/4 second to check for updates of messages, but be safe from people in anyway accessing it outside of the program. Any ideas? Thanx

p.s. code snippets are appreciated
