Question

In short I’m trying to implement a GUI to my networking app. Both of them have mainloop() so I’m trying to put them into separate threads and I’m using boost::thread for it.

    //standard initialization of boost::thread
    GuiThread.join();
    NetworkThread.join();

However, above crashes for some reason unknown. I’m searching for any way to do the same thing so any suggestion will be appreciated.

Thanks in advance, Red.

EDIT:

I’m creating boost::thread GuiThread of the wxWidgets mainloop like so:

    boost::thread GuiThread = boost::thread ( boost::bind( &myAppClass::MainLoop(), this));

and Networkthread same way.

then i rewrite wxApp OnRun() function like so:

    int OnRun() {
            GuiThread.join();
            NetworkThread.join();
            return 0;
    }

when i run it ( in vs2010 ), it says: myApp.exe has triggered a breakpoint and if i press continue it stops showing the window, if i press break it shows me assembly.

You must run wxWidgets main loop from the same thread that initialized the library. If you want to run it in a thread other than main, it means that you can’t use the standard IMPLEMENT_APP() macro but must do the initialization yourself, e.g. by calling wxEntry() manually.
