how to log off(sign out) windows 10 using uwp?
I have do in win-forms but codes are not working in uwp.
[DllImport("user32.dll")]
public static extern int ExitWindowsEx(int operationFlag, int rationReason);
private void button_Click(object sender, RoutedEventArgs e)
{
//Application.Current.Exit();
ExitWindowsEx(0, 0);
}
In non-UWP programme You can create a new process and run
%windir%\System32\shutdown.exe /l /t 0
But this is not available to UWP programmes. Check out the Stack Overflow link here for another take on this problem. But it looks like you are out of luck.
As i see your code above , you are actually closing the application. In UWP , Application works on states like Activated, Running, Suspended or Exited
If you want to log out from the application , it means that you would like to wipe of all user data and his Navigation History.
Make A function that clears the NavigationTrace and once the NavigationEntry is cleared , navigate the user to the login screen/home page

I am making an universal app and when i click a certain button, i need to open the webbrowser with a link. I got the link as a string in a variable but the windows 7 / 8 app ways such as "Proces" and Webbrowser objects give errors.
In windows apps, you can't simply open other apps/programms.
The only posibility is to use the Launcher:
Windows.System.Launcher.LaunchUriAsync(new Uri("http://www.google.de"));
The Launcher looks up the default program/app which is assosiated to the uri-scheme (in this case "http://" for webbrowsers) and forwards this call
others then above you can go Package.app manifest change the start page to the URL that you want or another method by using web control set the source to the URL you needed.
use scope async, it will open link to the mobile,PC default default browser for UWP
private async void Button_Click(object sender, RoutedEventArgs e)
{
await Windows.System.Launcher.LaunchUriAsync(new Uri("http://www.fmradiotune.blogspot.com"));
}
I am developing game for windows phone in unity3d, I have inserted Rate me button in game but on run time in windows phone it didn't work, is there any method to access AppID for the current application running in windows phone developed in Unity3d. I need code in unity3d CSharp for getting AppID.
I tried this C# code in Unity but It didn't work and having error no keywork found windows.
string appId = Windows.ApplicationModel.Store.CurrentApp.AppId.ToString();
LinkUri = new Uri("http://www.windowsphone.com/s?appid=" + appId, UriKind.Absolute)
Here I needed AppID to complete my link for rate me.
As far as i know Unity can not access the Windows namespace but you can make use of EventHandler to call 'Review Task' from Unity. You can do this by following below steps(visit Unity Expert for detailed explanation).
In Unity Game Engine-
Create Event -
using UnityEngine;
using System;
public static class events
{
//Create a new event
public static event EventHandler RateUs;
public static void FireRateUs()
{
Debug.Log ("Opening Rate Task......");
//If event is subscribed than fire it
if(RateUs!=null)
RateUs(null,null);
}
}
Fire Event -
using UnityEngine;
public class RateUs : MonoBehaviour
{
void OnMouseDown()
{
events.FireRateUs();
}
}
In Visual Studio IDE
Subscribe Event -
public MainPage()
{
.
.
.
.
events.RateUs += events_RateUs;
}
Call Function -
void events_RateUs(object sender, EventArgs e)
{
String AppId = Windows.ApplicationModel.Store.CurrentApp.AppId.ToString();
Windows.System.Launcher.LaunchUriAsync(new Uri("ms-windows-store:reviewapp?appid=" + AppId));
}
You have to get your AppID from your developer's portal on Microsoft Create's web page. You can then hardcode it into your app or save it as a static/globally available variable for accessing purposes. This would mean you would have to begin the process of creating your app entry prior to the programming of the rating game feature. Just create the entry, and don't submit it! Or create it, and add Rate app as an update. I'd choose the former method, personally!
For Apple and Google rating/submit information you have to create the entry ahead of time to get a SKU number. Also in iTunes/Apple/iOS/OSX you have to create the app and give it a unique name, etc in the developer's portal/certificate store.
im developin an app for wp7 that it holds pictures and notes with password login. But when app running if user press windows button app is running at background and if user press back button it resumes without asking password again.
i tried to Navigate when app activated but i couldnt manage it in Application_Activated method. is there a way to do that? Or could you advice me sth else that solve my problem.
ty.
here is my code im using to navigate,
(Application.Current.RootVisual as PhoneApplicationFrame).Navigate(new Uri("/MainPage.xaml", UriKind.Relative));
I got around this issue by using UserControls on the MainPage, showing one if the user had not yet logged in and the other if they had, I set these controls up to show/hide based on certains states in the MainPage and then bind that to the MainViewModel:
private void Application_Activated(object sender, ActivatedEventArgs e)
{
// Ensure that application state is restored appropriately
....your code here to load stuff...
App.ViewModel.MainPageState = "ShowThemTheLogin";
}
}
I am building a windows phone application (basically its a game but I am not using XNA, Silverlight was enough). The graphics are moving based on a DispatcherTimer. What I want to do is basically stop the timer whenever a call arrives on the phone, and start it again after the call has finished, so that the game state is not lost.
I tried with :
// Code to execute when the application is activated (brought to foreground)
// This code will not execute when the application is first launched
private void Application_Activated(object sender, ActivatedEventArgs e)
{
Game.timer.Start();
}
// Code to execute when the application is deactivated (sent to background)
// This code will not execute when the application is closing
private void Application_Deactivated(object sender, DeactivatedEventArgs e)
{
Game.timer.Stop();
}
but it did not work, it actually does not reach to this point when a call arrives at the phone. Anyone had such experience?
Thanks in advance :)
When a call is received you will receieve the Obscured Event on the Frame.
Please note that this event can also be fired for more than just a received phone call though.
I want to scroll down or up in the webbrowser control on the windows phone 7 using code behind (no javascript). i mean like using some button to scroll down for example. is that possible?
EDIT:
I tried to call a javascript function using InvokeScript, but it keeps giving me an unknown error 80020006. i tried to do this:
public MainPage()
{
InitializeComponent();
webBrowser1.Navigate(new Uri("http://www.msn.com"));
}
private void button1_Click(object sender, RoutedEventArgs e)
{
webBrowser1.InvokeScript("window.scrollBy(100,100);");
}
something wrong in my code?
There is no way to interact with the scrolling of the page inside a WebBrowser control from outside of it.
In terms of doing it with JavaScript look at windows.scrollBy()
update
Try webBrowser1.InvokeScript("eval", "window.scrollBy(100,100);");
But be aware that the page you're viewing may have overridden eval which coudl prevent this from running.
Note that the WebBrowser control was not intended to be used to view websites directly.
Also, have you tried calling scrollBy directly from within your own page?
