PowerBuilder Native Interface (PBNI) Part 1

The PowerBuilder Native Interface (PBNI) is a standard C++ programming interface that allows developers to extend the PowerScript language with C++ classes and to call PowerScript functions from C++ applications. Modeled after the Java Native Interface (JNI), PBNI provides a native vehicle that extends the functionality of PowerBuilder to that of the C++ programming language. Since its in... (more)

PowerBuilder Native Interface Part 3

The PowerBuilder Native Interface (PBNI) is a standard C++ programming interface that allows developers to extend the PowerScript language with C++ classes and to call PowerScript functions from C++ applications. Modeled after the Java Native Interface (JNI), PBNI provides a native vehicle that extends the functionality of PowerBuilder to that of the C++ programming language. In Part 2 (... (more)

PowerBuilder Native Interface (PBNI) Part 2 - Extending functionality

The PowerBuilder Native Interface (PBNI) is a standard C++ programming interface that allows developers to extend the PowerScript language with C++ classes and to call PowerScript functions from C++ applications. In Part 2, we'll create your first PBNI class and work with PBNI objects. In the following example, we'll build a very simple PBX that returns a string containing the text "Hello ... (more)

PowerBuilder 8.0 SSL Client Applications

Encryption, the process of scrambling data so that only trusted parties can unscramble it, stops unauthorized users from using intercepted data or login information passed between authorized users and servers. Today, Web-based network traffic is encrypted using the Secure Sockets Layer (SSL) encryption standard. The SSL protocol runs above TCP/IP and below higher level protocols, such as ... (more)
