Make the text file unreadable?

[barbara_dave]

Hi, all,


I'd like to know if there a way to make the text file unreadable. I
want the user to read file only in my program, but not allow to read
files from outside of my program. How to do that?


Thanks a lot!

Sounds like you need to encrypt your file, so that only your reader knows
how to decrypt it.

Marina,

That is not womans logic, however great answer.

I was not direct in my mind reading the question, while it is so obvious.

How to encrypt and decrypt the whole text file ? Can I get some
samples?

Thanks in advance

Barbara,

Search for Rijndael on MSDN than you get all kind of encryptions
(I live in a Rijndal which is in old Dutch Rijndael, and in that way I
remember it me)

I hope this helps
