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.
