How to open a text file only through my application but not others?

In my case, I have a file placed on a file server,
I can set the permission about the folder/file.

How can I let the user can read the file in the application I create
but they cannot direct access the file out of my application?

Cylix,

Is it possible that you did not close the writing, as well is there an extra
command for this.

I hope this helps,

Cor

If you don't want to use access this file as another user from your
program, you could concider crypting the contents. So when the user does
open the file it's rather useless.
