Getting Started with Flash Charts using RPG

Alex Roytman — Wed, 30 Sep 2009 16:04:24 +0000

Today, we will be talking to one of our RPG developers, Alan Smith, who will demonstrate an easy-to-use option for charting your IBM i data.

When it comes to viewing and analyzing data, a text-based interface may not be enough. Visualization can add a whole new dimension of understanding. While RPG wasn’t originally created for graphical representation of data, this task is surprisingly simple today with a browser-based interface powered by RPG. With the right approach and a little help from Flash, it takes very little effort to create stunning 2D or 3D charts and graphs directly from RPG code.

Using an AJAX Library on the IBM i

Today’s video is a response to a question from one of our viewers, Wil Rikken, from McNess BV in the Netherlands.

In my video on Sending AJAX Requests to the IBM i, I suggested the use of AJAX libraries, instead of coding everything from scratch. I also demonstrated a snippet of code that uses the ajax() function that we package with all our tools for the IBM i.

Wil wanted more details on this particular function. So, I have asked David Russo, the main developer and architect of our JavaScript AJAX library, to provide all the particulars on how to use the ajax() function with POST, asynchronous mode, etc.

I am also making the AJAX Library and the corresponding documentation available as a free download in our Resources Section on the site. You can access it here.

Generating an AJAX Response from the IBM i with RPG and PHP

Alex Roytman — Fri, 19 Jun 2009 22:05:50 +0000

Joining me in today’s video is one of our IBM i web developer/analysts, Hany Elemary. Together, we will continue to discuss AJAX by explaining how to generate a server response to an AJAX request from the browser. Hany will share his thoughts on how AJAX responses are similar to basic dynamic output pages that output data instead of HTML. We then go on to illustrate how AJAX response programs are built by providing examples in two popular IBM i (iSeries/AS400) web development technologies: RPG/CGI and PHP.

AJAX on the IBM i (iSeries / AS400) – What’s the big deal?

Alex Roytman — Fri, 20 Mar 2009 04:24:16 +0000

If you are modernizing AS/400 RPG or Cobol applications, you should be learning and familiarizing yourself with the concept of AJAX. Why is AJAX such a big deal?

To answer this question, I introduce you to something about browser development that you may not have realized. This realization explains why AJAX is so relevant. I then provide an example of how AJAX is used to simplify form processing for both developers and end-users.

Demystifying AJAX on the IBM i (iSeries / AS400)

Alex Roytman — Thu, 19 Mar 2009 22:48:23 +0000

As I talk to System i / RPG developers who are modernizing their systems, I get questions about what AJAX is all about and how it can be used when developing Web applications on the IBM i platform.

So, in this video, I introduce you to AJAX (or Asynchronous JavaScript and XML). As it turns out, the acronym is deceptive, and doesn’t really tell you much about how AJAX is used and what it really is.
