The PowerBuilder DataWindow object is a powerful presentation component. By using the built-in DataWindow functions within DataWindow object expressions, complex user interfaces can be developed, and by using PowerBuilder's Windows ActiveX control the same component can be embedded in a browser. With Pocket PowerBuilder, the same component can also be rendered on a Pocket PC device. All of these presentations can basically use the same code. The only changes required are those necessary to fit the resulting DataWindow in the space available. However, to generate a purely browser-based visual component, we must move beyond the functionality provided by the DataWindow and use those technologies that are available for browser user interface manipulation. The specific technologies that will be presented are DHTML, JavaScript, VB Script, Frames, and Cascading Style Shee... (more)

Extreme Data Windows

The PowerBuilder DataWindow object is one of the main reasons for the success that PowerBuilder has achieved as a software development tool. Together, they have matured and developed. However, since the beginning the DataWindow has been used to display and manipulate data in the form of lists and reports as well as in various data input and maintenance forms. Today, users are demanding a more dynamic user interface in which intuitive display and manipulation of graphical representation of data replaces the simple method of displaying and editing text data. The PowerBuilder DataW... (more)

Not Your Father's DataWindow

The DataWindow object is the key to the success of the PowerBuilder development tool. Together, they've matured and developed, but even in the earliest versions, we were retrieving and displaying data from local tables into reports, lists, or data edit screens. Today, developers use complex processes to retrieve data from a variety of sources into reports, lists, or data edit screens. Presenting data to the user in virtually the same format is the one thing that has stayed constant over time. PowerBuilder and, particularly, the DataWindow have greatly advanced behind the worksta... (more)

The PowerBuilder DataWindow as an Image Thumbnail Display Control

While external controls exist for viewing image thumbnails, there can be the need to view images as thumbnails within the context of other data within a multi-row list, treeview or report. This can be easily done with a PowerBuilder DataWindow object. In this case a treeview DataWindow (see Figure 1) was needed to display multiple images as thumbnails that related to the data presented in each row. Required functionalities include making the images selectable, displaying data for each thumbnail, such as the name of the file, and to keep the appearance orderly by having the images... (more)
