It appears that simply
turning on the “debug mode” control card makes the bug disappear…
Since this component is meant to be used by other users, I’d like to make
it operational in any situation.
It seems the stack is pointing
to TREXE.EXE. There is no problem with any other component (I tried randomly some
types), including the printer.
If I understood correctly
your previous message, you mean that the problem is coming from the Type65
itself? And that Type65 can’t be used with the type I developed?
Thanks a lot,

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

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.
