Last year I wrote an article in PBDJ describing an ASP.NET project that was done with DataWindow.NET in the browser ("Prognos," Volume 14, Issue 4) and PowerBuilder Web Services in the back end. The front end consisted of an intro page, two data entry pages, and one page with the resul...

In this article we're going to take a database and create our own mini version of an 'Amazon-like' item lookup. That is to say, any .NET or .NET-compatible client will be able to look up items in our database via the Web by simply providing a UPC. This article will show you how. To com...

Back in late 2002 I wrote an article on creating Web Services using PowerBuilder ('Implementing PowerBuilder-Based Web Services from PowerDynamo' http://pbdj.sys-con.com/read/42210.htm). It was based on a PowerBuilder 8.0 component deployed to EAServer called from Web pages based on Po...

It doesn't seem that long ago that Pocket PowerBuilder broke onto the scene; in fact it was only in August 2003 at TechWave. Since then the Pocket PowerBuilder engineers in Concord, MA, have churned out Pocket PowerBuilder 1.0.1 and are now releasing Pocket PowerBuilder v1.5 in January...

The mobile enterprise application development market is continuously evolving. A short time ago, developers were focused on building wireless Internet applications using technologies such as WAP.

Historically, the applications that we developers have written are targeted for desktop computers. Our clients have been confined to computer terminals, surrounded by four walls and connected to a network.

It has been some time since PowerBuilder was on top of the world, with human resource managers constantly on the prowl for developers with PB skills.

One cool feature in Pocket PowerBuilder is that you can include functionality that's not provided by the tool: accessing the Windows CE Application Programming Interface (WinCE API).

Since PowerBuilder Developer's Journal is now in its 10th year of publication, we asked a couple of old friends to share their thoughts and memories about the magazine.

What should you do if you have diverse components in your enterprise and need to access them from your Pocket PowerBuilder application? I won't spend too much time on SOAP and Web services, as there's lots of reading you can do on those subjects, especially if you have insomnia.

PowerBuilder has been a popular choice for client/server application development for many years and there are a half-million existing applications in production today.

PowerBuilder's recent evolution has provided us with more options for developing our applications. We can use PowerBuilder to develop within service-oriented architectures, .NET environments, multitier architectures, and more.

I recently participated in a development meeting in which handheld and database deployment was the main topic. Some participants became confused about the difference between a mobile and an embedded database as a result of this discussion.

I recently presented a case study on mobile business at a local ColdFusion Users Group in Salt Lake City. Two questions dominated the Q & A section. How productive can you be with a handheld and what tools can you use to create applications for it?

My goal in this article is to raise your awareness of the products available and give you enough information to go on if you choose to investigate them. I'll also discuss some of the main issues involved in searching for and selecting off-the-shelf products. Finally, this article ends ...

On my current project we're using PowerBuilder 7.0 to develop components to serve an ASP front end; however, the front-end developers wanted data sent to them in XML format.

With caching there's really only one objective - to improve performance. Not having to go to the database, the file system, or rerun some piece of business logic improves performance - EAServer shows you how using caching.

Since Web DataWindow technology is now used as a building block for many applications, Sybase decided to enhance this functionality and provide some much needed bug fixes. I recently met with the Web DataWindow team to demonstrate what I've been doing for my clients and to discuss some...

Blue Cross and Blue Shield of Rhode Island (BCBSRI) is one customer who's leveraged PowerBuilder and EAServer to develop an intranet solution. This application has provided BCBSRI with tremendous cost savings and enhanced performance.
