This section presents the following topics:
• Introduction (this page)
• ActiveX usage guidelines (this page)

FieldMaxII and a host application program. This DLL
has no GUI elements.
ActiveX
Usage
Guidelines
The following discussion explains how to use the Field-
MaxII ActiveX DLL server in an application program.
The DLL server package—provided by
Coherent—defines all ActiveX interfaces and object
classes. The user uses the functionality provided by the
ActiveX package to communicate with the FieldMaxII
meter.
Usage
Overview
To reliably communicate with the meter, the program
must provide infrastructure via the ActiveX server. A
number of object classes and interfaces that will aid in
setting up the infrastructure are provided.
