11. OLE Programming Interface
The programming interface to an application programme is executed as an automation (OLE-) server for 32-bit
Windows programmes (OLE = Object Linking and Embedding).
The communication between any application programme and FlintWeigh II will be done exclusively by the
following functions which are described below.
11.1. OLE Functions
