    Well, I don't do anything with JScript, so I wouldn't know...

    But in JavaScript...

    Code:
    if (testString.search(/\W/) != -1) {
  // String is good, contains only a-zA-Z0-9_
}
else {
  // String is bad, warn user
}
    Ofcourse, TIAMTOW, and I haven't even tested this code.

    I found a sweet script to do this somewhere. I think she's on my home machine though, so I'll send it later if I remember.
    Someone post here to remind me, and I'll see the reminder when I check my email at home later...
