i'm beginning in C++ Windows phone.
Currently i'm doing a windows phone app with many pages and i don't know how to save and load my data. I tried global variables and SQLite database but i always meet errors so i tried " Windows::Storage::ApplicationDataContainer " but i can't pass the variable between all pages.
is there someone who have a template that use ApplicationDataContainer or someone who could explain me how to use it?
here is my code

}
when i launch my application on my windows phone i seize my username and i click on my button to show the "menu.xaml" page, and i'm supposed to have get the name in this page thanks to the "localSettings" i've passed on my MainPage.xaml.cpp with the naavigate function.
To pass data from a page to another i used "Page::OnNavigatedTo" method.
So on my menuPage I created a global variable and i added a menu::OnNavigatedTo()
where i get data from previous pages.
here is my menuPage.xaml.cpp
#include "pch.h"
#include "menu.xaml.h"
#include "learn.xaml.h"
#include "level.xaml.h"
#include "records.xaml.h"

Since you're using Ninject, my recommendation is to use it to inject the session factory rather than an IHttpModule. To do so, create Ninject Provider classes as shown below. Note that this requires transaction management in code, I dislike the idea of blindly holding a transaction open during a request.
public class SessionFactoryProvider : Provider<ISessionFactory>
{
protected override ISessionFactory CreateInstance(IContext context)
{
return Fluently.Configure()
.Database(MsSqlConfiguration.MsSql2008.ConnectionString(c => c.FromConnectionStringWithKey("DefaultConnection")))
.Mappings(m => m.AutoMappings.Add(CreateMappings()))
.CurrentSessionContext<WebSessionContext>()
.BuildSessionFactory();
}
}
public class SessionProvider : Provider<ISession>
{
protected override ISession CreateInstance(IContext context)
{
var sessionFactory = context.Kernel.Get<ISessionFactory>();
var session = sessionFactory.OpenSession();
session.FlushMode = FlushMode.Commit;
return session;
}
}
Then in NinjectWebCommon:
private static void RegisterServices(IKernel kernel)
{
// session factory instances are singletons
kernel.Bind<ISessionFactory>().ToProvider<SessionFactoryProvider>().InSingletonScope();
// session-per-request
kernel.Bind<ISession>().ToProvider<SessionProvider>().InRequestScope();
}
I would like create my CustomQSpinBox .
This CustomQSpinBox must inherit of QPushButton and QSpinBox
but when I compile this code :
#include <QSpinBox>
#include <QPushButton>
class CustomQSpinBox : public QSpinBox, public QPushButton
{
Q_OBJECT
public:
CustomQSpinBox (QWidget *parent = 0);
~CustomQSpinBox ();
void initMinMax(int min, int max);
void init();
signals:
void needNumpad();
public slots:
void clicked();
};
I get an error :
erreur : C2594: 'static_cast'ÿ: conversions ambigu‰s de 'QObject *' en
'CustomQSpinBox *'
How I must do my inheritance ?
Yes, when the numPad is closed, the value is set in the QSpinBox. The problem is so to open the numPad when I click on the QSpinBox.
For the moment I manage with this code :
#include <QSpinBox>
#include <QPushButton>
#include <QMoveEvent>
#include <QResizeEvent>
class CustomQSpinBox: public QSpinBox
{
Q_OBJECT
public:
CustomQSpinBox(QWidget *parent = 0);
~CustomQSpinBox();
void resizeEvent(QResizeEvent *event);
void moveEvent(QMoveEvent * event);
signals:
void needNumpad();
public slots:
void clicked();
private:
QPushButton * button;
};

The problem at hand is that your namespace and your form class both share the name Form1. You have to disambiguate the symbol by specifying that it's the class within the namespace.

await m_mediaCaptureMgr.CapturePhotoToStorageFileAsync(imageProperties, m_photoStorageFile);
}

}
However, when I click on the initializeButton, I got an exception:
UnauthorizedAccessException (Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)))
What could be the problem here?
EDIT: I found the bug. Basically, if the webcam is already initialized, trying to initialize it again will trigger an exception. So I had to put in a flag, and some try/catch
Have you set the capabilities for Microphone and Webcam in the manifest file?
Seect the Microphone and Webcam capability in Package.Appmnifest file
