Здравствуйте собственно перехватываю вставку флешек
проблема вся в том что не приходит DBT_DEVTYP_DEVICEINTERFACE так как в ней содержится dbcc name
Буква вставленной флешки определяется
вот код
mainwindow.h
C++ (Qt)
#ifndef MAINWINDOW_H
#define MAINWINDOW_H

}
if (gt==DBT_DEVTYP_DEVICEINTERFACE)

cout<<"voshel"<<endl;
}
}

cout<<"BUKKKVAA="<<t<<endl;
cout<<"NAME="<<as.toStdString()<<endl;
}
}
}
return QMainWindow::nativeEvent(eventType,message,result);
//return false;
}
в чем может быть проблема
таким образом вот это условие не выполняется
C++ (Qt)
if (gt==DBT_DEVTYP_DEVICEINTERFACE)
{
cout<<"voshel"<<endl;
}
