Il lancio di Appeon Mobile rende finalmente concreto lo sviluppo mobile di applicativi PowerBuilder, in maniera semplice e veloce, e senza la necessità di fare ricorso ad ulteriori tecnologie. Con Appeon Mobile si sfruttano i propri skills Powerbuilder, con le sofisticate caratteristiche di gestione dati che gli appartengono, per costruire apps complete e "data centriche" deployabili su qualsiasi dispositivo mobile dotato di sistema operativo iOS, Android, Windows Phone ecc. Il webcast illustra le principali caratteristiche di questa tecnologia rivoluzionaria per lo sviluppo di soluzioni aziendali mobile, evidenziando inoltre le diverse possibilità che Appeon Mobile offre nella realizzazione di interfacce "user friendly", nonchè le problematiche connesse. Il tutto mostrando una app iOS esemplificativa, realizzata con PowerBuilder e Appeon Mobile, denominata: Genepesca Retail Solution.

Costruire apps iOS con PowerBuilder? E' semplice con Appeon Mobile!

Stumbled upon an interesting post on Yahoo Groups about the future of PowerBuilder, what the average developer can do to improve PB education and where SAP needs to improve their marketing, such as posting use-cases, tutorials, YouTube videos etc. It's a long and interesting thread, below find a link to one of the more informative posts.

Power Object Yahoo Group

Chris Pollach's latest blog post looks at events and precedence: "The order in which events happen within a PowerBuilder Classic application is in most cases, a very predictable model. The PB developer should be aware of this aspect when developing GUI based applications. For instance, when focus is shifted from one object to another object, the first object will experience the Modified and LoseFocus events before the second object experiences a get focus event."

Implementing Datawindow Usability Improvements with Minimal Disruption

Tuesday, Decembre 4th, 2012
9:00am PST (Los Angeles)/18H00 CET (Paris)

This presentation covers techniques to create and implement a 'datawindow enhancement service' within an existing PowerBuilder application with the goal of providing improved functionality while keeping disruption to application users to a minimum. It is similar to the session presented at the 2012 PowerBuilder Developers Conference held in October in conjunction with SAP TechEd. Focus for this session will be on the creation of the service object, implementing example functionality enhancements with existing datawindows, and ideas for further expansion of the service.

PBTV has all your best straight from this year's PowerBuilder Developer's Conference. Come check out Tuesday October 30, 10AM PST on PBTV, come check out George Mikhailovsky present on 'Creating and Consuming Web Services Based on SQL Queries in PowerBuilder.'
Unlike direct connections to the database, Web services can be managed and secured outside of an application and used by any Website or client/server, Web, or mobile application. A PowerBuilder application then can use Web services to return data sets as data sources of the application's DataWindows. This facilitates the incorporation of PowerBuilder applications and Web services into a cloud computing environment. This session explains and demonstrates how to:
Build a data store based on a chosen query and structure that can be used for constructing Web service output.
Create a class (NVO) as a wrapper of a Web service with the necessary Get_...()? functions that populate arrays of structures from respective data store(s).
Deploy a created Web service to an IIS Web server including the creation of a WSDL file.
Create a DataWindow with a Web service as a data source.
Choose a proper Web service and find its desired method (Get_...()? function).
Select a proper parameter from the chosen Web service method and finalize the created DataWindow to solve hidden problems with the string data type.

You asked, he answered!

Find below the questions and answers from Bruce Armstrong's (originally done by Oscar Tobar) presentation on Best practices for managing exceptions and errors in PowerBuilder.

Are there any performance benefits to using this?

Aren't you still going to end up with just as much code, just in a somewhat different order? (In fact, more code, because you have all those extra objects, e.g. your custom exceptions.)?

Actually, RuntimeError has a lot more Properties than Throwable, so wouldn't it be better to inherit from it?

How can I control some VM errors from code ??

Etc
