Hi all
what really happens in the background and what is true? i have queried two current AI engines and get different answers. Does it depend on whether you are making a new application or deploying an existing one?
We are using PB/PS 2022 R3.
Our input to the AI engine:
When I convert a power builder application to Power Server, the DataWindows still look exaxtly the same way as before. Are they really rendered with HTML, CSS, and JavaScript?

When you convert a PowerBuilder application to PowerServer, the DataWindows do indeed maintain their original look and feel, which might give the impression that they haven't changed. However, they are actually being rendered using modern web technologies such as HTML, CSS, and JavaScript.
Here’s a brief explanation of how this works:
- DataWindow Conversion: During the conversion process, the DataWindows are transformed from their original PowerBuilder format to web-compatible formats. This means their definitions are converted into HTML for structure, CSS for styling, and JavaScript for functionality.
- Rendering: In the PowerServer environment, the converted DataWindows are rendered by the browser using these web technologies. This is why they appear the same as in the original PowerBuilder application – the conversion process ensures that the appearance and behavior are preserved.
- JavaScript Libraries: PowerServer uses specific JavaScript libraries that replicate the behavior of PowerBuilder DataWindows. These libraries handle the interactions, data binding, and other functionalities, ensuring a seamless user experience.
- Styling and Layout: The CSS ensures that the styling and layout of the DataWindows are consistent with what you had in PowerBuilder. This includes fonts, colors, alignments, and other visual aspects.
- Interactivity: JavaScript is used to handle the interactive elements of the DataWindows, such as data manipulation, event handling, and other dynamic behaviors.
The conversion process is designed to be as transparent as possible to the end user, so while the underlying technology changes, the user interface remains consistent. This approach minimizes the learning curve and ensures a smooth transition from a desktop application to a web application.
In summary, yes, the DataWindows are indeed rendered using HTML, CSS, and JavaScript after the conversion to PowerServer, even though they retain the same appearance and functionality as in the original PowerBuilder application.

No, while Power Server offers some improvements over PowerBuilder for web applications, DataWindows in Power Server are not rendered with HTML, CSS, and JavaScript.
Thank you in advance for your comments.
Here's a breakdown of how DataWindows work in both environments:
- PowerBuilder: DataWindows are native controls within the PowerBuilder application. They are rendered using the application's own graphics engine and don't rely on web technologies.
- Power Server: While Power Server can create web applications, DataWindows here still maintain their native rendering approach. They are not converted into HTML, CSS, and JavaScript for display in a web browser.
However, Power Server offers some advantages for DataWindow presentation in web applications:
- Data Window Web ActiveX control: Power Server can leverage the Data Window Web ActiveX control to present DataWindows within a web page. This control acts as a bridge between the server-side Power Server application and the client-side web browser.
- Enhanced data access: Power Server can improve data access for DataWindows in web applications by providing connectivity to various data sources.
If you're specifically looking to achieve web-based rendering with HTML, CSS, and JavaScript for your DataWindows, you might need to explore alternative solutions beyond Power Server. Some options include:
- Third-party reporting tools: Several third-party tools can generate HTML, CSS, and JavaScript output from your DataWindow designs.
- Custom development: You could develop a custom solution that translates DataWindow definitions into web-compatible formats.
