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.
You can take advantage of the capabilities of the Web DataWindow
by:
- Hand coding against the Web
DataWindow component 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.
