Hi Rémi,
This sounds like your component corrupted memory that type 65 is
trying to use.
Did you start TRNEXE.EXE from within your C++ project? Then you
should get a call stack and be able to identify where the problem is caused.
If it is inside TRNEXE, you can open then TRNDLL (FORTRAN) workspace
and run your project from there – in case it is due to some weird behavior
inside TRNDLL, it shows you what goes wrong on the FORTRAN side.
If you get the stack pointing to something in TRNEXE.EXE both
times, you’re in trouble (then it is linked to the Online component
itself). In that case, I would try to reproduce the problem with another
component (plain printer, …).
Be sure to have debugging on everywhere while hunting for the
bug: C++ workspace, TRNDLL workspace, Deck (NAN_CHECK 1, OVERWRITE_CHECK 1 =
Var 9 ‘debug mode’ = true in Simulation Studio).
Finally, if your C++ component uses graphical elements via MFC,
there might be a problem handling state ( AFX_MANAGE_STATE, http://msdn.microsoft.com/en-us/library/ba9d5yh5(VS.80).aspx ).
Good luck,
Werner

Objet : [TRNSYS-users] problem using plotter : Type65
Hi
everybody,
I
just developed a new component in C++. When I put a Type65 in my deck and
launch the simulation I receive the “invalid floating point” error
message, even if Type65 is not linked to my component. Strange thing is that if
I right click two times on the plotter (like “pause” and
“resume” the simulation) everything works correctly. I checked in
debug mode and with a printer, all variables and outputs are correct.
I
use global variables to stock my data so there may be a problem with the
allocated memory…
Thanks
for your help.
