Removing spaces from a string with coldfusion
Ran into this problem today and it seemed to take quite a long time for me to find a solution so I'm posting how it works here for the benefit of others. This method uses a regular expression to do it's bidding.
<!--- set up a test variable --->
<cfset mySpaceFilledString = "a brand new combine harvester" />
<!--- remove ALL spaces from the string --->
<cfset mySpaceFreeVariable = ReReplace(mySpaceFilledString, "[[:space:]]","","ALL")>
<!--- check it works --->
<cfdump var = #mySpaceFreeVariable#>
this returns "abrandnewcombineharvester" - all spaces removed from the whole string
To simply remove the spaces at the beginning and end of a string (a form field for example) it's much easier...
<!--- set up a test variable --->
<cfset form.myTestString = " mark mcaulay " />
<!--- remove spaces from start and end of the string --->
<cfset mySpaceFreeVariable = Trim(form.myTestString)>
<!--- check it works --->
<cfdump var = #mySpaceFreeVariable#>
this returns "mark mcaulay" - only the spaces at the start and end of the string have been removed
Hope this helps someone!

**UPDATE - Just for good measure, and of course, to keep James happy ;) here is the equivelent in php
<?php
// set up a test variable
$mySpaceFilledString = " a brand new combine harvester ";
// remove all spaces from the string
$mySpaceFreeVariable = str_replace(" ", "", $mySpaceFilledString);
// check it works
echo $mySpaceFreeVariable;
?>
this returns "abrandnewcombineharvester" - all spaces removed from the whole string

To simply remove the spaces at the beginning and end of a string (a form field for example) it's again, much easier...
<?php
// set up a test variable
$myFormVariable = " mark mcaulay ";
// remove spaces from start and end of the string
$myTrimmedVariable = trim($mySpaceFilledString);
//check it works
echo $myTrimmedVariable;
?>
this returns "mark mcaulay" - only the spaces at the start and end of the string have been removed

next up is a couple of shortcuts i've discovered...the first is to add a HTML comment, select the html you want to comment and press ctrl+shift+c....job done!...and for a coldfusion comment press ctrl+shift+m ...can't be easier than that can it?
will add more as I discover them, feel free to join in though.
