Advanced PowerBuilder

External Functions

PowerBuilder offers you hundreds of functions to use, while developing applications. PowerScript suffices in most of the situations, but there are situations where functions that are written in languages other than PowerScript, are required to be called from within the PowerScript. For example, you may want to know the free space left on a specific drive, memory (un)used, etc... PowerBuilder didn't provide you functions for these purposes. Sometimes, you may want to access functions from a third-party DLL --a DLL that is not from Powersoft and operating system. PowerBuilder provides you a way to access external functions.

In This Session You Will Learn About:

• Declaring external functions.
• PowerBuilder compatible Datatypes with C++ Datatypes.
• Local & Global External functions.
• Completing "w_about" Window.
• Examples of Multimedia.
