The function was made possible using <code>tf.range</code> and <code>tf.shape</code>. Without further ado, here is the working gen... |

Getting a character to be represented by an int 0-25 <p>I'm working on a cryptography program that implements various traditional methods. For some of them it is best for my message to be represented as numbers 0-25.

There is no <code>ViewBag</code>in DNN's Razor Host module since it only works with a Model. You can use <code>PageData</code> instead.
