Generating a unique random number between 2 numbers
<p>For my specific purposes, I need to generate a whole number between 1 and 120 inclusive (which I can do no problem).  </p>

<p>Once that number has been generated, I need to pull it from the pool so it can't be generated again.  </p>

<p>Continue this process until all numbers are exhausted, at which point, the pool fills back up and we start over again.</p>

<p>How could I go about doing this?</p>
