Here is a fun challenge for those of you who have to deal with specific sized divs that contains dynamic text. What do you do with a div that you cannot or do not want to resize dynamically. Today, I have two solutions for you.

The first and simplest technique would be to use CSS to hide overflow content.

Lets take a simple piece of code.

One problem that I ran into while creating PDF's in Coldfusion recently was with including images. Despite using what I thought was a valid path (since it would show up in my browser) and using the correct syntax, my images were showing up as red x's. I found out that there is a little trick to including images in a PDF in CF.

I figured when I first started this project that it would require the use of CFPDF in order to create a PDF in Coldfusion - wrong. CFPDF is only used to manipulate already existing PDF's.

It is the CFDOCUMENT tag that you use to actually do the initial creation.

Here is an example of how you would create a PDF and output it to the browser window:

Here was a problem that occurred for me the other day that you all may have encountered. When I was attempting to upload certain image files, Coldfusion would throw an error!

"An exception occurred while trying to write the image. Ensure that the destination directory exists and that Coldfusion has permission to write to the given path or file. cause : coldfusion.image.ImageWriter$ImageWritingException: An exception occurred while trying to write the image."

I ran into an interesting issue today where I was trying to grab some query information from Coldfire but none of the Coldfusion information would load. I went into Coldfusion Administrator and double checked that my IP Address was in the "Debugging IP Addresses" listing. I then opened up a couple other pages and Coldfire was able to pick up the necessary information from them.

I was updating some ColdFusion old code and had a brain freeze about how to wrap items from a ValueList() function in single quotes, so that I could use them in a query.

Fortunately I found this article from Cold Fusion Jedi. Just use QuotedValueList() instead of ValueList() - each item in the list will be surrounded in single quotes. For example, if ValueList(query.alphabet) returns a,b,c,d, QuotedValueList(query.alphabet) will return 'a','b','c','d'.

If you want to have arbitrary characters (instead of single quotes) around your list items, use ListQualify(). Continuing the example above, ListQualify(ValueList(query.alphabet),":") would return :a:,:b:,:c:,:d:.

I hope this helps somebody!

This was an interesting error that I encountered today. About two months ago, I added a bunch of cfqueryparams to the page that began returning this error today, "Error Executing Database Query. [Macromedia][SQLServer JDBC Driver]Value can not be converted to requested type.". I assumed the value being passed to the cfqueryparam was actually invalid.

Last week one of my team members gave a presentation to the rest of us on Coldbox. We are using this framework for a project and we were discussing the basics of convention and how to work with the different layers - which brought up the question, where exactly is the optimal place to put the Javascript in this?.

I used this opportunity to bring up the CFHTMLHEAD tag, which allows you to place code into the head tag from anywhere on the page. This would allow us to keep Javascript from loading on unnecessary pages and still keep everything componentized. I also thought this would be a good opportunity to discuss basic CFHTMLHEAD usage.

Cfmail in cfscript Here's a convenient little function I use for some of my more processing oriented pages. I love building content in cfscript however I find it really annoying having to close my cfscript tags to mail content. In general I don't like closing cfscript tags for anything if at all possible.
