I am sure this question is simple so it should not take you smart guys long. I have some text in a RichTextBox1 and i want to turn each character(letter) into a number then i am going to add a number to it say "1" and then save it to a file as a long set of numbers, when i want to read the info the program will subtract the number "1" and then turn the corresponding number back into a letter(character) and put them back in the richtextbox1 does anyone know how to do this? or maybe an easier way to go about it in vb .net

THANKS!!!
