Why should ColdFusion analyze the query results when the database could do it and you could save the bandwidth for something that really needs it? In Part 1 of this article (CFDJ, Vol. 3, issue 10) I introduced stored procedures and performed some basic tasks with them. In this article I show how to do more complex tasks that involve IF/ELSE statements, looping, and string manipulation. First, see Listing 1; how often have you had to do something similar? Let's say you just received a note from your product supplier stating that Item 20 has a new, lower everyday price of $15. Now your store is running a special in which you give away certain items, but you can't remember if Item 20 is one of those items. You could either look up the item and its cost and then decide whether to send another request to the database to update the price, or simply tell the database whic... (more)

Rob Gonda's Two-Part AJAX Special: Now In One Part

It's become very popular lately, even though it's not exactly new. It's been possible to use the concept behind AJAX since browsers introduced the XMLHttpRequest function in 1999. AJAX isn't a technology, or a language, and there's no recipe to implement it; it's just a combination of various components to achieve something you otherwise couldn't: asynchronous http requests. However, since early 2005, when Google and Flickr popularized the concept, its use has grown rapidly. The name AJAX is short for Asynchronous JavaScript and XML. It uses the JavaScript XMLHttpRequest function to create a tunnel from the client's browser to the server and transmit information back and forth without having to refresh the page. The data travels in XML format because it transmits complex data types over clear text. AJAX uses XHTML for the data presentation of the view layer, DOM, sho... (more)

Is Ulitzer a New Trend or the Ultimate Death of Journalism?

I must confess I am very new to Ulitzer as an online channel of social communication media. But I am delighted about its raison d'être. However, I cannot but ask these questions: Is Ulitzer the beginning of a new trend or the ultimate death of journalism? Or is it the glorification of e-journalism? The realization of new journalism practice in the age of Web services and Internet Technology? These series of questions are being answered everyday as the new social media moguls and barons and baronesses of the Internet Media launched another online media channel, one after another. We must give kudos to the visionaries among us who realize the powerful role of Internet technology and quickly seized on its powerful promise by giving voice to every kind of idea and thought under the sun. And what has technology not redefined yet? Think about it, from e-retailing to e-democr... (more)

How Healthy Is Your ColdFusion Server?

Before describing this month's prize and contest, I would like to thank everyone for their submissions to our first contest (CFDJ vol. 7 issue 3). That contest objective was to modify Ray Camden's blog in any way you choose, and you had to take advantage of at least one new feature in CFMX 7. Announcing the Winners of Challenge #1 The winners are Nahuel Foronda and Laura Arguello from Blue Instant (www.blueinstant.com/). They chose to use Flash Forms and Web Services to create a weather pod. I plan to migrate horwith.com to a new server in the near future, and when I do, their pod will be there as well. I also believe Ray Camden is going to make the pod available for download from his site, either as part of the next version of his blog or as a separate add-on to his blog. Congratulations, Laura and Nahuel. Challenge #3 As many of you know, I spend a huge amount of my... (more)

Where's ColdFusion Headed Under Adobe?

Adobe has been very successful in selling into the enterprise. This can only help ColdFusion going forward," says Dave Mendels, in this exclusive interview with ColdFusion Developer's Journal. Here Dave discusses "Scorpio," how the ColdFusion product development team is already hard at work devising the best way to harness synergies between CF and Adobe's LiveCycle products, and more. Simon Horwith: You must be very excited about the completion of the Adobe acquisition. Can you share your thoughts on what it will be like working at Adobe? Dave Mendels: Adobe is an innovative, exciting company that I'm thrilled to now be a part of. As we've worked through the details of the acquisition, it has become clear to me that Adobe and Macromedia share a common vision and commitment to customers and technology innovation. We have overlapping customers, and not that much ove... (more)

What's New with Flex, ColdFusion, and More

Simon Horwith: Today I'm speaking with Ben Forta, the technical evangelist for Adobe. The first thing I have to ask you is - the acquisition has happened, Adobe is now controlling ColdFusion and has taken over everything that Macromedia was doing, and this is my first chance to really speak with you since that happened - what is going on in the ColdFusion world? How has the acquisition gone for the ColdFusion team and yourself and what's in store for us in the near future? View this interview on SYS-CON.TV Ben Forta: Thus far, not a whole lot has changed. Before the acquisition we were hard at work on ColdFusion Scorpio. We first mentioned it over a year ago, the next major version of ColdFusion. That work began pre-acquisition and it's ongoing. We're still working through the specs and futures and what the price should be. Independent of that, also pre-acquisition,... (more)

Implementing HTTP Basic Authentication

Most ColdFusion applications that require users to be authenticated follow the pattern laid out in the official ColdFusion documentation and in the ColdFusion MX Developer's Guide. This HTML forms-based method is perfectly serviceable, but as applications become more complicated it's not uncommon to run across issues with session expiration and deep linking/bookmarking. This article describes an alternative method of implementing user authentication that's based on the mature and time-tested authentication scheme laid out in the original HTTP specification. Without making the application significantly more complex, it can route around many of the most common limitations of traditional forms-based authentication. An Overview of Forms-Based Authentication To start off, let's take a look at some typical ColdFusion code that uses forms-based authentication from the poin... (more)

Web 2.0: The State of Confusion?

Increasingly, industry pundents, seasoned developers, and bloggers alike are labeling “Web 2.0” as nothing but jargon and a new spin on old technologies. In this session, Coach Wei will examine the state of confusion around “Web 2.0,” debunk the myth that Web 2.0 doesn’t involve new technologies, and finally answer the question: How is Web 2.0 meaningful to the enterprise? Believe it or not - Web 2.0 will fundamentally impact core enterprise IT operations in a way that can only be matched by the shift from mainframe computing to client/server computing!
