It generally is used to comment out a line of text, I belive. :)

Not for Regex.

# at the start of a regex string is used as an inidicator that the regex pattern starts (and another one at the end to indicate the end of the regex pattern).

You could also see /PATTERN/, and there are a few others as well.

If you specify the x pattern modifier, it does specify a comment line.

vB does use the # character as the regex delimiter as merk stated, but you can choose just about any character as the delimiter.
