    Run your application through the debugger, you'll see what triggers that.

      @SGaist i think in one qtreewidgetitem i can't find element. So i can't use qtreewidget because if i use show me this error ASSERT failure in QList<T>::operator[]: "index out of range", file C:\Qt\5.5\msvc2013_static\include\QtCore/qlist.h, line 545

      And when i run with debug show me this:
      https://i.imgsafe.org/35f6161b6a.png

      I can't use mode debugger ->> this is other problem that i had i dont know why show me this.

      But my problem basically is i need to check all time because the values change ? you understand so if i save in one var i dont know the actual value i think . Or i'm wrong?

        @SGaist In other words the presence change and when i try to access and the presence is unvailable take me this error. Because i'm trying to access with the presence unvailable.

          As silly as it may sound: don't access it when you know it's not there.

                Because you're likely using Visual Studio and you didn't install its debugger.

                One simple way to avoid that kind of crash is to check the list size before accessing any of its element.

                    Did you grab the debugger from Microsoft web site ? If so and you didn't modify the defaults when installing, it will be automatically detected.

                                    What is your exact setup ?

                                    You wrote that you were using Qt for VS2013 and now you are looking for VS2015 ? You know that you can't mix and match libraries built with different version of Visual Studio ? These compilers are not compatible one with the other.
