Top Stories by Richard Gorremans

One of the most common requests made by users when they see data displayed on a Web page is that they want to be able to view the information sorted by columns. Working with a database makes this request fairly simple; working with arrays is, or at least was, a problem. Why use an array? No ColdFusion programmer would volunteer to do such a crazy thing. In a recent project, where our team was pulling loan information resultsets from a mainframe repository, I did just that. The loan information was being stored in a data structure that contained multidimensional arrays created with WDDX calls to the mainframe. We always want to keep the users happy, so the Internet was searched, several routines for sorting multidimensional arrays were found and tested, and the users were promised that they would be able to dynamically display the results in different sorted orders ...

ColdFusion MX: A Web Services Example

From the first day the Internet was conceived, its primary goal was to allow people to access information stored on remote computers. Over the last couple of years, the technology of Web services has evolved not only to enhance accessing this information, but to share it as well. Web services are in action everywhere. When you see 20-minute delayed stock quotes on a Web site, or you track eBay auctions on another, you are most likely seeing Web services in action. Look a little further and you'll find Web services that can provide these functions as well as spell checking, addr... (more)

Sorting Multidimensional Arrays

In my last article we looked at how to sort multidimensional arrays by creating a second single-dimensional array that is used as a key. The focus of this article is how to sort multidimensional arrays by creating a query object that can be sorted in the same way you would an ordered result set from a database. In truth, this article will demonstrate two methods: one for ColdFusion 5.0 and a second, far superior method using the tag introduced with ColdFusion MX. The first step is to build a small multidimensional array. The example code below shows daily sales for ... (more)

Making Headlines

In Part 1 of this two-part article (MXDJ, Vol. 2, issue 3) I showed how to invoke a Web service for the purpose of validating user input. Part 2 will delve a little deeper into the ColdFusion MX language structure specifically designed to handle XML result sets such as those returned from a Web service. The goal is to consume a Web service that will return headline news articles for a user-specified topic. When finished you will be able to add a live user-interactive newsfeed to your Web site. This article will cover: XmlParse(): Returns an XML Document object XmlRoot property: ... (more)
