For example I could set a pattern of "[)(*&^]" how would I code it to
exclude those values?

.Pattern = "[^)(*&\^]"

Note the \ that precedes the second ^. The first ^ defines the character
sequence as negative and the \ escapes the second ^ so it's included in the
negative character sequence.

I don't believe there is any need to escape the ^ in VBScript. Both by
testing, and by documentation, it seems to be unnecessary.

"If the caret character appears in any other position within the list, it
matches itself, that is, it has no special meaning. "


--ron

Of course, that only applies when the ^ appears within brackets as other than
the first character.
