Web DataWindow
The Web DataWindow is a thin-client DataWindow implementation
for Web applications. It provides most of the data manipulation,
presentation, and scripting capabilities of the PowerBuilder DataWindow
without requiring any PowerBuilder DLLs on the client.
The Web DataWindow uses the services of several software components
that can run on separate computers:
- Web DataWindow
server component running in an application or transaction server - Dynamic page server
- Web server
- Web browser
- Database
The server component is a nonvisual user object that uses
a DataStore to handle retrieval and updates and generate HTML. You
can use the generic component provided with PowerBuilder or a custom
component.
There are several ways you can take advantage of the capabilities
of the Web DataWindow:
- Web DataWindow
design-time control In a Web target, you can use the Web DataWindow design-time
control to generate server-side scripts that access the Web DataWindow
component. This is the easiest way to use the Web DataWindow. - Hand coding against the Web Target
object model In a Web target, you can write server-side scripts that use
the Web Target object model to access the Web DataWindow component.
The Web Target object model provides a set of predefined objects
and methods that simplify coding against the Web DataWindow component. - Hand coding against the Web DataWindow
component itself You can write server-side scripts that access the Web DataWindow
component directly. - Writing your own HTML generator Using a sample PBL provided with PowerBuilder as a starting
point, you can create your own HTML generator that provides the
methods you need for your application.
