Question hex view component

[secwarriror]

hi people,

I am currently working on a base64 encoder/decoder. What the program needs to do is
1. First get the user input in a rich text box.
2. Display the hex values of the user input besides the rich text box.
3. convert the hex values to corresponding base64 encoded hex value.
4. convert the hex values to ascii value


1. user input text box ---> 2. hex view of user input
4. base64 encoded ascii output <--- 3. base64 encoded hex view


The above representation is how I want the app to graphically look, with all its components placed as mentioned.

Now I want to know which is the best component or best way to display a hex view in vb.net?

Thanks in advance.
