Hello...

I'm creating my own encryption-of-sorts on my application. The application is VERY simplistic so I don't need any hugely complicated encryption.

Basically,

I want my program to automatically convert characters in a string. I already know the conversion method that I'm going to use I just need help with the syntax.

So, in plain english, what i need is code that will

For each letter in STRING.

Replace A with B (case statement?)

Until the end of the string.

Here's a basic example. Say I want to use the following encryption (we'll just use numbers for now, since there's only 10 of them).

User enters "1234567890" into a textbox and presses encrypt.
My application goes through the string, one character at a time and checks for the 'switching' rule. In this example i'll use
1 becomes 2
2 becomes 3
...etc...
9 becomes 0
0 becomes 1

So, in textbox two the "encrypted" string would be: 234567890

Can someone help me with code on this please? I"m a newbie and I think my theory works for what I want to do, just not sure the most efficient way to do this.
