In this article we'll discuss connectivity requirements, Informix-specific data type processing, and the use of Informix stored procedures within the PowerBuilder environment. PowerBuilder offers developers four specific connectivity options for IBM Informix databases: Third-party Open Database Connectivity (ODBC) drivers Third-party Java Database Connectivity (JDBC) drivers Third-party OLE-DB providers The "native" driver available in the PowerBuilder Enterprise version In this article we'll focus on the last option by discussing connectivity requirements, Informix-specific data type processing, and the use of Informix stored procedures within the PowerBuilder environment. Connecting to Informix Supported Versions The PowerBuilder native driver for Informix connectivity (IN9) is linked with the IBM Informix ESQL C product to provide connectivity to the following IBM ...

.NET Features Analyzer

The release-defining feature of PowerBuilder 11 is its ability to deploy existing applications as .NET Windows Forms and Web Forms applications and components of business logic, namely custom-class user objects (NVOs), as .NET assemblies and Web Services. Although PowerBuilder's adoption of the .NET Framework represents a great leap forward for application developers, the implications of converting a desktop, client/server application to an ASP.NET Web application are significant. Those of you who have been working with PowerBuilder 11 know this first hand just from the sometimes... (more)

Introduction To PBNI

Have you ever thought of adding new features to PowerBuilder? Or wanted to call Java or .NET from PowerScript? Or imagined that you can call PowerScript from C++ or Java? With PBNI, you can do them all and more. PowerBuilder Native Interface (PBNI) is a standard interface for third parties to extend the functionality of PowerBuilder. PBNI is a valuable new addition to the PowerBuilder programmer's toolbox that allows developers to reach beyond the already feature-rich constructs of PowerScript and custom class user objects (commonly referred to as nonvisual objects or NVOs). The... (more)

EAServer Problem Analysis & Troubleshooting

Designing and implementing an n-tier or Internet application is a complex task, and issues resulting from errors in the runtime configuration or the application code itself are practically inevitable. Problem analysis and troubleshooting are part art, part science. Therefore, although the techniques discussed here can be helpful, the sheer diversity of client and server environments precludes a single recipe for resolving all issues. We'll focus on problems that involve PowerBuilder that occur from the point of connectivity all the way through an EAServer component's lifecycle, an... (more)
