Avoiding Code Duplication: A Sample Exercise

Wed, 23 Nov 2005 19:15:00 EST

The purpose of these articles is not a tutorial with step-by-step instructions but a guide to assist in the design and development process. Our goal is to help new developers get started in the right direction and to avoid pitfalls. This month's column will center on pitfalls with the Web target.

PowerBuilder Standards and Frameworks

Thu, 27 Oct 2005 16:15:00 EDT

Now that we understand workspaces and targets, we can start to get a feel for what type of infrastructure we want to use for our application. As I mentioned in my last column (PBDJ, Vol. 12, issue 7), we need to answer some questions regarding standards and frameworks.

Getting Started with PowerBuilder

Thu, 15 Sep 2005 12:00:00 EDT

When Bruce Armstrong contacted me about writing a PowerBuilder Beginner's column I agreed almost immediately. The reason for this is that there are many existing PowerBuilder applications in production and their original developers have moved to other positions or left the companies that wrote them.

Exploring the Web DataWindow Part 2

The DataWindow is used extensively in most PowerBuilder applications. It accounts for as much as 75% of the objects in the application. The reason for this is the power of the DataWindow and its ability to present information from the database and allow new records to be added or existing records to be updated.

PowerBuilder 8/4GL Web

Wed, 01 Aug 2001 00:00:00 EDT

My last article (PBDJ, Vol. 8, issue 6), which introduced PowerBuilder 8 and Web targets, demonstrated how to create Web pages from within the PB development environment. This article reviews the 4GL Web server-side event model and discusses how it helps reduce development time and effort. Using this event model allows developers to concentrate on business logic and interface design rather than the low-level details of accessing EAServer components.

PowerBuilder 8 Web Targets

Fri, 01 Jun 2001 00:00:00 EDT

I realize that many people are talking about nothing but Java, and yes, I'm writing Java components myself; however, PowerBuilder still lives on. There are many existing PowerBuilder client/server applications in production that need to be maintained and many that need to be moved to the Web. PowerBuilder 8 has some nice development features that make it an environment for PowerBuilder applications as well as Web applications. This article discusses the new user interface and concentrates on Web targets.

The Web DataWindow Update Process

Sun, 01 Apr 2001 00:00:00 EST

The development of the Web DataWindow is a great technological advancement. It's extremely helpful in moving an existing PowerBuilder application to the Web. Most PowerBuilder applications contain many DataWindows for the various screens and reports. The ability to quickly render these controls as HTML in a browser is a huge timesaver.

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 additional functionality that's needed in the Web DataWindow. I'm pleased to say that PowerBuilder 7.0.2 C3 contains many bug fixes that the community has been waiting for as well as four new features.
