This is an update of Paul Miller's RegEx. It will cut out literal &lt;&gt; but I haven't fully tested it, it's just a quick fix since his didn't work all that well.
I also took out the \s. You could add this back in but I use this for very simple password verification, and I certainly have no use for spaces in my passwords. |

Expression |
(?!^[0-9]*$)(?!^[a-zA-Z]*$)^([a-zA-Z0-9]{6,15})$ |
Description |
I built this expression to test a string in ASP for valid username and password constraints. It can be adapted for any number of scenerios. For instance in this case, we needed to ensure the username someone wanted was not all numbers or all letters and was 6-15 characters in length with no special characters. This expression tests negatively for all number cases, then all letter cases, and lastly tests for only alphanumeric characters in the required range. In other words: the match must be alphanumeric with at least one number, one letter, and be between 6-15 character in length. |
