ExternalSim CallBack problem

[Ufeseros]

Hello



here is my problem :

I have a dll that work fine in the v1.2 of prepar3D but not in the v2.2

it seem to be that the callback function is called only once in the v2

Do you have any ideas where it could come from ?



thank you

[minime]

Can you extract the relevant source code and post it here?



Also, in your debugger you can see when your DLL is loaded and unloaded.... can you check if it is still loaded when the callback is not being called?

I cant post the real code but, here a example witch had the same problem.



Code:
// test_dll_prepar3Dv2.cpp : définit les fonctions exportées pour l'application DLL.
//

#include "stdafx.h"
#include "stdio.h"
#include "globals.h"




#define EXTERNAL_SIM_CALLBACK_MASK (SIMCONNECT_EXTERNAL_SIM_CALLBACK_FLAG_CREATE | SIMCONNECT_EXTERNAL_SIM_CALLBACK_FLAG_DESTROY | SIMCONNECT_EXTERNAL_SIM_CALLBACK_FLAG_SIMULATE | SIMCONNECT_EXTERNAL_SIM_CALLBACK_FLAG_LOCATION_CHANGED | SIMCONNECT_EXTERNAL_SIM_CALLBACK_FLAG_EVENT)

}
g_VehicleList.clear();
}



there is the console output on prepar3D 1 :







and on prepar 2:







also i can't check with the debugger, Prepar3D and visual studio are not on the same computer.

i forgot to said :



on the first console i take the screenshot before the "simulation" start , but when its start i have the "**SIMULATE**" output



But the prepar3Dv2 console stay like this, but if i close prepar3Dv2 i have the output "sortie" called in the DLLstop
