Well according to the documentation the NetAPI MFC wrapper should work with
FoxAPI & AimAPI.
Here is a snip from the Documentation (BO400BJ rev B):
-------------------------------------------------------
Chapter 1 Overview
The class provides a C++ wrapper around an extensive library of C language
calls developed earlier
with Networked FoxAPI(tm) software and AIM*API(tm) software. The class provides
a thread-safe
connection interface, and simplifies the interface requirements, as developers
use fewer, more
advanced C++ methods, and yet have all of the functionality and access of the
earlier APIs.
----------------------------------------------
Thanks
Peter

Well, I think that confirms that your application is not supported using
FoxAPI. You're lucky that it reads using FoxAPI, but when trying to write, it
crashes because NetMFC is only supported using AIM*API. Looks like you'll have
to shell out for an extra AIM*API license. Isn't Invensys great?

Hi Tim
We also have PI and have had no problems writing into the Foxboro system
using v4.3.1 or v4.3.2 of FoxAPI.
However the PI api was written using the true FoxAPI C-calls (not the
Net-MFC wrapper)
The problem we have is a completely different application (not PI) that was
compiled with the Net-MFC wrapper that can read from both FoxAPI & AimAPI
however can only write to AimAPI.

Peter,
Are you absolutely sure you are running FoxAPI v. 4.3.2? We have v.8.4.2 in
Hawaii, and just yesterday, we were trying to do writes from OSI PI, and FoxAPI
kept failing. We double-checked our version by using d:/opt/fox/ais/bin/foxtst
and selecting option "1229" from the prompt (there is no menu pick for the 1200
series of commands - nice design there, Invensys). This reported that the
FoxAPI version we were using was 4.3.1. We had a FoxAPI v.4.3.2 installation
CD available, so we went and loaded it on the v.8.4.2 box, and now the writes
work correctly from PI.
You should verify the version, and if you really are running v.4.3.2, then it
looks like the issue is with the netMFC class client application. It reads to
me from Alex's e-mail that netMFC class client applications are only compiled
to work with AIM*API. At least that's how I read it. Here is the pertinent
passage in Alex's e-mail that leads me to that conclusion:
"FoxAPI/netFoxAPI using the FoxAPI client which supports OM, Historian, and CSA
calls.
AIM*API/NetAIM*API using the netMFC client which supports OM, Historian, and
CSA calls."
I hope that helps you figure out the problem.
Tim
