• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

QT and DLLMain issue

Hi everybody,

Firstly i'm sorry for my english.

I come to u because I spend more time on this issue and Im not able to solve it.

I try to use QT inside a DLL project. But when I wrote a piece of QT code inside my C++ project, the dllStart function is not running when the DLL is launching.

Code: 
#include <QApplication>
#include <QPushButton>

void DLLStart(void)
{
MessageBox(NULL, L"DLLStart!", L"DLLStart!", MB_ICONEXCLAMATION | MB_OK);

int argc = 1;
char** argv;
argv = new char*[1];
argv[0] = "toto";

try
{
  //QApplication app(argc, argv);
}
catch(char* lEx)
{MessageBox(NULL, (LPCWSTR)lEx, L"DLLStart!", MB_ICONEXCLAMATION | MB_OK);}
}

If someone has an idea ?

Thx in advance.

Bonjour, votre anglais est meilleur que mon francais! :)

I assume this is for a SimConnect client, correct? Make sure you have specified a .def file for DLLStart and DLLStop and it is being fed to the input of the linker. The instructions on how to do this are located near the top of the SimConnect documentation page.

Also, here is a sample project that uses SimConnect in a DLL. Obviously it doesn't use QT, but it might be able to help you out.

Hope that helps! If you are using QT creator for this instead of Visual Studio that might complicate things a bit, but I'm sure it can still be done.
