Need to check Naming Conventions (string manipulation)

[nexus]

Hi! I need to make a function to check that users are following a specific naming convention. I'm thinking about making an array with all the acceptable characters, or an array with all the unacceptable characters. However, each time I need to check a string, I'll have to compare every character of the string to everything in the array (worst case). Is there some better way to do this? Thanks.

WHY first of all?<br>
Then if you must put them in a table.<br>
and search it using SQL (fastest)<br>
Or how about an Input MASK?<br>

don't ask me why we need to check naming conventions. anyhow, seems they don't care about runtime, so I'll just write crude but functional code! I'll be working for Microsoft in no time... hehehe. Thanks for your help!
