Eureka!! Richard your suggestion make me think and i found that i didn't call PySys_setArg in python initialization!!!

I just added in the script
if len(sys.argv) < 1:
sys.argv.append("")
and everything works fine!!!

the line is

plt.plot([1,2,4],[1,2,3])

Well if i compile boost 32bit everything is fine. The problem is with 64 bit.
I tried installing winpython 32bit and 64bit

I don't think this is the case. I already added all the references but the errors still appears

You were right....looking more deeply into the eigen documentation i found the answer to my question. It is a page i never noticed. It is in the section "understanding eigen"

Hi tra_la_la_la,

ok if i make explicit the constructor both the assignment pass through B::operator=(A&) but i would like to know what is the logic behind this.
Why the A a is considered is some way differente from the object that the addition operator returns?

Unfortunately i don't have control on the component that calls my library. I could only check the value at the beginning of the function call. But i can only guess that maybe an explicit _controlfp in the source code changes the precision of FPU.

sorry for the delay,
there is no need to free the library.
After the macro is executed the Design mode unsets automatically and i need to set it again in order to compile the c++ dll

Optimistic76 24-Feb-17 3:05am View

well, your suggestion help me to make me look deeper in excel options!
Finally I found that if I turn on the Design Mode everything works fine!!!
so thank you!

Believe me Graeme_Grant, i tried the solutions that i found on google but no one seems to work!

Optimistic76 15-Apr-14 13:26pm View

well,

the fact that i would like to use QWaitCondition instead WaitForsingleObject is just for the reason I want to develop crossed-platform apps.
I don't think I'm making a mistake using a Qwaitcondition object inside a lock. Look better at the link you suggest me to look in the "Detailed Description" section.....

is the application the target you want to past the text instead of Notepad?
HWND WINAPI FindWindowEx(
_In_opt_ HWND hwndParent,
_In_opt_ HWND hwndChildAfter,
_In_opt_ LPCTSTR lpszClass,
_In_opt_ LPCTSTR lpszWindow );

when you call for the first time FidWindowEx, you will get the handle of the first edit. You should call another time FindWindowEx using the result of the first call as the hwndchildafter parameter

I don't need synchronization between the two functions, but i need timer triggering.
i wrote "synch" in the question title because of the fact that the first function delays the second timer execution.I hope i explained the problem. Sorry i'm not english..

I need timers that execute in its own thread... Timer in QT are different?

Optimistic76 5-Dec-13 9:06am View

I surely agree with you but my problem is to have the two function running at the same time.
do i have to use queue timers?

Optimistic76 5-Dec-13 8:34am View

Thanks, I suspected that.

And if i start worker threads from the callback functions? In this situation the time to execute the functions would be only for the creation of the threads.Inside the threads there'll be the real execution.Is It a good scenario?

Optimistic76 13-Nov-13 10:44am View

Yes, I'm sure. This is the only version we have at work. I know it is old, but if my boss dosn't buy a new version, i have to try with this...
