Back in Oct 2005, SysCon published an article I wrote in CFDJ magazine. Unfortunately, the Webmonkey.com tutorial I originally based my article on has been removed by Wired. I contacted them and hopefully they'll dig it up and repost it under their new wiki site. In the meantime, here is a link to the CFC file zipfinder.cfc used in that article. One more note...

We have a great meeting planned for both intermediate as well as brand new CF developers. This meeting is Wednesday, Nov 5th at Easel Training. Room 1) Kurt Wiersma - BlazeDS Have you ever wondered what BlazeDS is and what it can do? If so this session is for you. We will cover how you can install BlazeDS inside of CF and how CF can communicate with BlazeDS to make Flex applications get real time messages from ColdFusion.

Just got back from the BFusion/BFlex conference and wanted to summarize my weekend. I joined a few local CF developers and we drove 11+ hours to Bloomington, Indiana to attend this FREE 2-day conference put on by some of the Adobe User Groups in conjunction with Indiana University. Day 1 was ColdFusion focused, and I was in the Intermediate Track. We spent a full day of hands on training learning about the Mach II framework.

I've started working with a new client over the past couple of weeks. Ken Wolfbauer and Kathi Wolfbauer of Seal Guard Systems who approached me to help with their HTML and SEO. We have been working together in their great showroom in Blaine, MN. I've suggested that they move their site under ColdFusion. I'm looking forward to working with Ken and Kathi to promote their products and services on the Internet, including Milgard fiberglass windows and Metro steel roofing.

If you have a ColdFusion page that contains a form with text inputs or uses URL params, make sure you are not vulnerable to a XSS attack. I'm quite novice at this myself, but learning more about it recently. Here are some inputs to try in your forms or URL param values, if they echo the value back to the user after the page submits/reloads.

If you get an error page like this, and are scratching your head as to why, it's probably an infinite loop in your CFML code. The error I had was this, and sure enough, I had an out of control loop. 500 ROOT CAUSE: java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOf(Arrays.java:2882) at java.io.CharArrayWriter.write(CharArrayWriter.java:105) at coldfusion.runtime.CharBuffer.replace(CharBuffer.java:37) at coldfusion.runtime.CharBuffer.

Here is a code snippet that makes the ColdFusion processing "sleep" for the specified number of milliseconds. This works on ColdFusion MX 6 and above, which can expose the Java language from within CFML. ColdFusion 8 introduced a new sleep() function. The above code and the new function are explained in more detail in this ColdFusion Cookbook article.

I've been working on a small project at work to allow a user to click a link from an event registration confirmation email, which will open a .ics file in the browser. This special file is in the iCalendar format, and is recognized by MS Outlook, Mozilla Sunbird, and other calendaring tools. It creates an entry in your calendar, with a 30 minute reminder alert, to help you remember to attend the webinar event you registered for. I learned from the vCal() function on cflib.
