At work, Lisa takes advantage of her employer's dedicated T-3 to quickly access live NASDAQ quotes via a Java applet stock ticker. She spends each day alternating between development work and day trading. Soon to be rich, she dreams of early retirement and a life filled with leisure activities and day trading at home. Back at home her lack of patience and 56K connection make day trading a painfully slow torture. Java and 56K aren't meant to be together. Unfortunately, most of the 50 million regular Internet users worldwide are ecstatic if they can even achieve 56K. High-speed connectivity is common to businesses but is out of financial reach of the average home-based Internet user. To be successful, consumer-targeted Web sites have to provide content quickly, because consumers won't wait. So while businesses enjoy IP-delivered, feature-rich Java applications and ap... (more)

Advanced WebDW HTML Generation

Okay, so I've been promoting the inclusion of PB client/server articles, yet here I am writing about the Web DataWindow. Don't stop reading! This article applies to all PB developers, whether n-tier or client/server. That said, I now have to prove that this article is important to client/server developers.... Here's my angle: HTML has become a standard beyond Web development. People doing work unrelated to the Web, even nonprogrammers, need to learn the basics of HTML. Here's an example: I'm a consultant and I invoice my customers using QuickBooks. When I generate my invoices I ... (more)

n_ds DataStore Coupled to Parent Window in PFC 6.0+

Last year, after migrating a client's application from PFC 5.0.02 to 6.5, then applying some enhancements to take advantage of new features, the program began giving the following PFC error message: "For certain functionality the PFC DataStore requires a reference to its parent window. One of these cases has been encountered. To let the DataStore know who its parent window is, call the of_SetParentWindow() function after the DataStore creation." At first I was disturbed that the PFC developers had coupled the DataStore to a parent object. And worse, not only a parent object, but... (more)

The Software Tool Wars

A goal of major software tool companies (Microsoft, Oracle, Sybase, Sun, etc.) is to provide every design and development tool, connectivity product and server necessary for customers to design, develop, implement and maintain their enterprise systems. That's a tall order but within reach of each of those four companies. The EAStudio product set, which includes PowerBuilder, now contains a wide variety of tools in all those areas. However, until PowerDesigner 7 (PD7) was released, that set didn't contain an object designer. Last month I highlighted the new features in PowerDesign... (more)

The Evolution Continues?

Another TechWave issue? You bet! In addition to our content changing to flow with the currents of technology, our schedule is also changing. We've been moving up the schedule each month with the goal of getting on the magazine racks by the first of the month rather than the middle, which has been the case for quite some time. The July issue was going to be the TechWave issue because we hadn't anticipated having the August issue ready by July 30. After getting July out earlier than expected, we went full speed ahead on this issue and I'm now proud to say we're back on schedule. Bo... (more)
