 Software that is not used is useless. Facing the challenge that doctors prefer to spend time with their patients rather than facing the monitor, we have fine-tuned methods in our DataWindow-based forms so that user entry is quick, painless, and a pleasure. These include the use of drop...Aug. 7, 2009 01:45 PM EDT Reads: 1,065 |
 This is the second part of an ongoing series about the new features that were added in PowerBuilder 11.5. In the first part, we looked at the Federal Desktop Core Configuration (FDCC) and the impact it had on developers. In this part, we’re going to look at a number of the improvements...Jun. 12, 2009 06:15 AM EDT Reads: 1,943 |
 TecnoTRENDS has been using PowerBuilder as its main development platform for years. The ultimate reason for choosing PowerBuilder was the versatility of the Sybase DataWindow control available under this platform. In short, the DataWindow control provides a significant productivity boo...Feb. 13, 2009 12:15 PM EST Reads: 972 |
 One of the typical problems developers face when using the HTML DataWindow (HTML DW) is that there's no SetRowFocusIndicator() method to allow users to see which row is the current one. This can confuse the user and lead to errors. For example, without a current row indicator users may...Jan. 1, 2009 12:00 AM EST Reads: 1,132 |
 This article talks about the ease with which DataWindows can be designed and consumed in a Microsoft Visual Studio 2005 environment. The DataWindow .NET version 2.5 has the infrastructure to support this concept. With the earlier versions of the DataWindow .NET, such as 1.0, 1.5 and 2....Sep. 1, 2007 03:00 PM EDT Reads: 9,580 Replies: 1 |
 It will come as a surprise to no one that PowerBuilder's native graphing capabilities are somewhat lacking. Even the Define Graph Style dialog for the DataWindow graph style seems to have been left out of the GUI update in PowerBuilder 10.5 (see Figure 1). Forget Windows 95, this looks...Aug. 1, 2007 01:15 PM EDT Reads: 10,570 |
 The current version runs with DataWindow.NET 2.0 and uses PowerBuilder 11 Web Services. To keep the installation slim it uses no database; instead the data is stored in DataWindows or XML files. Prognos makes use of AJAX techniques and accesses .NET classes from PowerBuilder for XML ha...Jun. 5, 2007 11:30 AM EDT Reads: 12,221 Replies: 1 |
 DataWindow display formats aren't a big secret. Most PowerBuilder developers use them to format numeric, date, time, and string values properly. Such display formats are usually straightforward and contain characters that have special meaning for a specific datatype like '#' for numeri...Mar. 14, 2007 12:00 PM EDT Reads: 10,379 |
 Let's suppose that you have a search window where a user can enter a search string and get the list of text items matching this pattern. Ideally, the portions of text that meet the search criteria should be highlighted, for example, by text formatting.Aug. 17, 2006 08:45 AM EDT Reads: 15,674 Replies: 3 |
 One of the first things you'll notice when you open up the File->New->DataWindow dialog in DataWindow Designer 2.0 is the new TreeView DataWindow presentation style (see Figure 1).

 Microsoft Visual Studio has excellent multi-language support both at design time and runtime, while Sybase DataWindow.NET doesn't have that. In this article we'll consider how to implement multi-language data presentation using DataWindow.NET. DataWindow.NET has two integral parts.

 In the early 1990s, before Windows 98, before Windows 95, before Windows NT, even before Windows 3.1, the DataWindow was being hatched by a small team of developers in Massachusetts. By small, I mean a single developer, Kim Sheffield - the 'Father of the DataWindow.'Nov. 13, 2005 05:00 PM EST Reads: 18,465 Replies: 3 |
 Last month we saw how DataWindow.NET technology can be a benefit when used for data presentation and data access in a Windows Forms (WinForms) application.

 PowerBuilder novices know the problem as well as seasoned PowerBuilder developers. You build a window in the window painter. You arrange the controls on the window and the layout looks fine.Apr. 30, 2005 09:45 AM EDT Reads: 20,105 |
I recently had the opportunity to rewrite one of our major data entry systems. This system processes payments on a monthly basis, either individually or submitted as a group under an administration company - rather like companies that have a third party handle their payroll.

 Let's face it - rewriting an existing application from platform to platform is not fun.

In the coding life of every programmer there's often a need to create a view of data that extends variably both to the right and vertically. Using a grid presentation style usually solves this problem. But what about when a programmer needs more control over presentation style? Jan. 1, 2002 12:00 AM EST Reads: 10,501 Replies: 1 |
The development of the Web DataWindow is a great technological advancement. It's extremely helpful in moving an existing PowerBuilder application to the Web.

 We've spent two articles now on Sherlock (PBDJ, Vol. 7, issues 8 and 10). This is an application that will use dynamic DataWindows to create reports for the example database provided with PowerBuilder. Using this tool we'll learn about dynamic DataWindows and how to create them.Feb. 1, 2001 12:00 AM EST Reads: 9,550 |
A component that's sitting on EAServer doesn't do us any good unless we call it from somewhere. We may call these components from several different sources. In this article we'll call them from the Active Server Pages (ASP) front end. Jan. 1, 2001 12:00 AM EST Reads: 10,987 Replies: 1 |
To this day my mother refuses to make deposits via her bank's ATM. Her reason is a valid one: she doesn't trust a machine with her money. You get no real validation from the ATM, just a receipt stating the amount you said was in your envelope. Jan. 1, 2001 12:00 AM EST Reads: 9,669 |
In the October issue of PBDJ we worked on the design for our mail server on Jaguar. This is more accurately called an MDA, or Mail Delivery Agent.

We've finally reached the end of this series - the fifth and final installment on graphing techniques. By the end of this article you should know enough about graphing to be really good at it.

In my previous articles on graphing (PBDJ, Vol. 7, issues 2 and 3) we created a simple line graph. We then extended the graph in order to have a tool tip that would work with it.
