[thelist] Stripping two VbCrLfs

[Chris Blessing]

Along with replace(), you could use this as well:

<%
dim strLineOfText
strLineOfText = "Line of text." & vbcrlf & vbcrlf & vbcrlf

' note that for some reason, vbcrlf = vblf in the above text.
' VBS seems to do this a lot, so you may need to check for both chr(10) and
chr(13)
do while right(strLineOfText,1) = chr(10) or right(strLineOfText,1) =
chr(13)
	' as long as there is a line-feed at the end of the string, lop it off
	strLineOfText = left(strLineOfText, len(strLineOfText)-2)
loop

' add one line feed to the end
strLineOfText = strLineOfText & vbcrlf

' view the source of the resulting HTML to see:
' <P>BEGIN<BR>Line of text.
' <BR>END

response.write("<P>BEGIN<BR>" & strLineOfText & "<BR>END")
%>

Using the replace() method is much easier (obviously) but if you have any
other need for a double-line-feed in the text itself, it too will become a
single line-feed, so watch out! =)

> Line of text

> Line of text

> But I want it to be written like so:

> Line of text
> Line of text
> Line of text
