This is not possible. This information store in registry and can be change any program. You can test this registry code in startup your program, but if user don't start your program, any other program can change.
I would suspect that you would need to encrypt the file. Although it could still be viewed with notepad, your program would only have the encryption key to decrypt it. You can also make a file association so that any file 'double clicked' with the .csj extension would bring up your program to decrypt it. Make a search here and on other sites for encryption to start you on the right track.

I believe it might be possible to write a program with a three letter extension made of unprintable characters?
Why would you wish to do this?
