Hi, we use jQuery. It's very low overhead. Search for jquery-barcode online.
The code is very simple, for example this code (call it index.cfm) generates a barcode from a parameter passed to the page (URL.code) e.g. index.cfm?code=12345
<cfparam name="URL.code" default="12345">
<html>
<head>
<script type="text/javascript" src="jquery-barcode/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="jquery-barcode/jquery-barcode.js"></script>
<script language="JavaScript">
function bc() {
$('#bcTarget').barcode('<cfoutput>#Trim(URL.code)#</cfoutput>', 'code128', {barHeight:50, barWidth:1, showHRI:true, fontSize: 11});
}
</script>
</head>
<body onLoad="bc();">
<div id="bcTarget" style="font-family: arial; font-weight: bold;"></div>
</body>
</html>
Using client-side code takes the pressure off the server a bit. There are CF barcode generators too, but they invariably end up using third party things like ActiveX and/or JavaScript, so jQuery-barcode is worth a look.
