External dependencies
For VDF applications to run correctly, a number of external dependencies need to be in place:
MSXML
Microsoft XML Core Services (MSXML)
Vincent Oorspung has implied that MSXML version 2 is the current version used by Visual DataFlex. However, Microsoft no longer support version 2.
GDI+
Microsoft Windows GDI+ is a class-based API for C/C++ programmers. It enables applications to use graphics and formatted text on both the video display and the printer. Applications based on the Microsoft Win32 API do not access graphics hardware directly. Instead, GDI+ interacts with device drivers on behalf of applications. GDI+ is also supported by Microsoft Win64.
GDI+ is used by the Graphics Library from DAW, currently in Beta.
Note: GDI+ is not officially supported for use within a Windows service.
