I've got question. I have application which is a phone book. I would like to create Tile (in Windows Phone main screen) which'll call that number after I click Tile on main screen.
Is that possible? What should I do to make something like that? I can create custom Tile or maybe I should create some method after my application start?
Create the live tile with something like the following code:
string number = "000 - 000 000";
ShellTile tile = ShellTile.ActiveTiles.FirstOrDefault(t => t.NavigationUri.ToString().Contains("phone=" + number));
if (tile == null)
{
StandardTileData tileData = new StandardTileData();
tileData.Title = "Call " + number;
ShellTile.Create(new Uri("/MainPage.xaml?phone=" + number, UriKind.Relative), tileData);
}
And then override the OnNavigatedTo in MainPage.xaml, and add the following code:
protected override void OnNavigatedTo(NavigationEventArgs e)
{
if (NavigationContext.QueryString.ContainsKey("phone"))
{
string number = NavigationContext.QueryString["phone"];
PhoneCallTask task = new PhoneCallTask();
task.PhoneNumber = number;
task.Show();
}
base.OnNavigatedTo(e);
}
If you have not done it yet, you also need to add the "ID_CAP_PHONEDIALER" capability in the WMAppManifest.xml file, or you will get an exception when calling task.Show(); above.
Now you got a live tile that when clicked will launch the application and call the number (The user must still confirm it in a dialog though, and that is something you can't disable)
Have you tried a flip tile and the using something like this:

Write the number to isolated storage then when they click the tile you read the isolated storage and call the number.
You can also use the Mangopollo library from CodePlex to create a secondary live tile: http://mangopollo.codeplex.com/

I'm trying to implement geofencing in Windows phone 8.1. First I wanted to create a sample Project to understand how it Works, but i couldnt make it works. What I'm trying to achieve is basically, I'll set the coordinates and close the app by pressing back button and it will trigger a toast notification when the phone is in the area of interest.
I've created a blank Windows phone(silverlight) 8.1 Project(geofence_test_01) and added a Windows RT Component Project(BackgroundTask) into the same solution. Added a reference for BackgroundTask in the geofence_test_01 Project.
ID_CAP_LOCATION is enabled in the app manifest.
MainPage.xaml has only one button to start geofencing.
<Button Name="btnStart" Content="Start" Click="btnStart_Click"/>
In btnSave_Click, I call a method which creates the geofence and registers the background task.
private void btnStart_Click(object sender, RoutedEventArgs e)
{
Init_BackgroundGeofence();
registerBackgroundTask();
}
private async Task Init_BackgroundGeofence()
{
//----------------- Crating Geofence ---------------
var geofenceMonitor = GeofenceMonitor.Current;
var geoId = "building9";
var positionBuilding9 = new BasicGeoposition()
{
Latitude = 47.6397,
Longitude = -122.1289
};
var geofence = new Geofence(geoId, new Geocircle(positionBuilding9, 100),
MonitoredGeofenceStates.Entered | MonitoredGeofenceStates.Exited,
false, TimeSpan.FromSeconds(10));
geofenceMonitor.Geofences.Add(geofence);
}
private async Task registerBackgroundTask()
{
//----------------- Register Background Task ---------------
var backgroundAccessStatus =
await BackgroundExecutionManager.RequestAccessAsync();
var geofenceTaskBuilder = new BackgroundTaskBuilder
{
Name = "GeofenceBackgroundTask",
TaskEntryPoint = "BackgroundTask.GeofenceBackgroundTask"
};
var trigger = new LocationTrigger(LocationTriggerType.Geofence);
geofenceTaskBuilder.SetTrigger(trigger);
var geofenceTask = geofenceTaskBuilder.Register();
}
And finally, in BackgroundTask, I've the following code:
namespace BackgroundTask
{
public sealed class GeofenceBackGroundTask : IBackgroundTask
{
public void Run(IBackgroundTaskInstance taskInstance)
{
var geofenceMonitor = GeofenceMonitor.Current;
var geoReports = geofenceMonitor.ReadReports();
var geoId = "building9";
foreach (var geofenceStateChangeReport in geoReports)
{
var id = geofenceStateChangeReport.Geofence.Id;
var newState = geofenceStateChangeReport.NewState;
if (id == geoId && newState == GeofenceState.Entered)
{
//------ Call NotifyUser method when Entered -------
notifyUser();
}
}
}
private void notifyUser()
{
var toastTemplate = ToastTemplateType.ToastText02;
var toastXML = ToastNotificationManager.GetTemplateContent(toastTemplate);
var textElements = toastXML.GetElementsByTagName("text");
textElements[0].AppendChild(toastXML.CreateTextNode("You are in!"));
var toast = new ToastNotification(toastXML);
ToastNotificationManager.CreateToastNotifier().Show(toast);
}
}
}
I get no error when building and deploying this in the emulator. I set a breakpoint in the backgroundTask but I've not seen that part of code is called yet. It never hits the breakpoint. I test it by using Additional Tools of the emulator, in Location tab, by clicking somewhere in my geofence area on the map, waiting for a while, but it never hits the breakpoint. Hope somebody can tell me what i am missing here...
I've checked these following links to build this application:

---- Some clues
Thanks to Romasz, I've checked the Lifecycle events and i see "no background tasks" even after registerBackgroundTask() is executed.... Apparently there is something wrong/missing in registerBackgroundTask() method.
I've tried to build my sample (it was easier for me to build a new one) basing on your code and it seems to be working. You can take a look at it at my GitHub.
There are couple of things that may have gone wrong in your case:
remember to add capabilities in WMAppManifest file (IS_CAP_LOCATION) and Package.appxmanifest (Location)
check the names (of namespaces, classes and so on) in BackgroundTask
check if your BackgroundTask project is Windows Runtime Componenet and is added to your main project as a reference
I know you have done some of this things already, but take a look at my sample, try to run it and maybe try to build your own from the very beginning.
Did you add your background task in the Package.appxmanifest under Declarations with the correct supported task types (Namely Location)?
In my Windows Phone app's main page, users can click a button to do some stuff and that will trigger the live tile to update.
The problem I am having is, if the user clicks the button and then hit the phone's Back button really quickly, the live tile sometimes will not render properly. This issue rarely happens, but it does happen and when it happens it just looks bad...
The way I implement the live tile is, create a user control that looks exactly the same as the live tile and then save it to isolated storage. Then retrieve it and store it in a FliptileData object. Finally I call the Update method on the ShellTile. Please see the following piece of code to demonstrate the process.
// the function that saves the user control to isolated storage
public Uri SaveJpegToIsolatedStorage(FrameworkElement tile, string suffix, int tileWidth = 336, int tileHeight = 336)
{
var bmp = new WriteableBitmap(tileWidth, tileHeight);
// Force the content to layout itself properly
tile.Measure(new Size(tileWidth, tileHeight));
tile.Arrange(new Rect(0, 0, tileWidth, tileHeight));
bmp.Render(tile, null);
bmp.Invalidate();
// Obtain the virtual store for the application
IsolatedStorageFile myStore = IsolatedStorageFile.GetUserStoreForApplication();
using (IsolatedStorageFileStream fileStream = new IsolatedStorageFileStream(IsolatedStorageFileName + suffix, FileMode.Create, myStore))
{
try
{
bmp.SaveJpeg(fileStream, tileWidth, tileHeight, 0, 100);
}
catch (Exception)
{
return null;
}
}
return new Uri("isostore:/" + IsolatedStorageFileName + suffix, UriKind.Absolute);
}
// save the user control to isolated storage and prepare the FlipTileData object
wideFrontTileImage = SaveJpegToIsolatedStorage((UserControl)this.WideFrontTile, "_wide_front", 691);
var flipTileData = new FlipTileData();
flipTileData.WideBackgroundImage = wideFrontTileImage;
return flipTileData;
// update the live tile
var shellTile = ShellTile.ActiveTiles.FirstOrDefault();
shellTile.Update(customTile.GetFlipTileData(data.UndoneMemosCount == "0" && data.TotalMemosCount == "0"));
I think the reason that's causing all this is, when the user clicks the Back button too quickly, the OS terminates all the processes running within the app and the rendering wasn't done at that time. I'm thinking if there's a way to know when the rendering is finished, so I can cancel the Back button and wait until it's finished then manually exit the app. But I simply dunno how...
Any help on this one will be greatly appreciated!
I have ran into similar issue in my WP8 app. The problem was that I was updating my Tile in ApplicationDeactivated event handler. The thing is you should not update your tiles there, but rather in your MainPage.OnNavigatedFrom override. Once I changed this, it works just fine.
I am getting a list of objects in Windows Phone, and show them in a listbox with databinding.
some image urls are not valid, so after every object is added in the list, i run the following code to check and replace, if not valid
private void CheckLinkUrl(Person p)
{
Uri filePath = new Uri(p.img_url);
string correct = p.img_url;
HttpWebRequest fileRequest = HttpWebRequest.CreateHttp(filePath);
fileRequest.Method = "HEAD";
fileRequest.BeginGetResponse(result =>
{
HttpWebRequest resultInfo = (HttpWebRequest)result.AsyncState;
HttpWebResponse response;
try
{
response = (HttpWebResponse)resultInfo.EndGetResponse(result);
}
catch (Exception e)
{
p.img_url = "http://somethingelse.com/image.jpg";
}
}, fileRequest);
}
the problem is that it is very slow, it takes sometimes 2 minutes+ to load every image (although the UI remains responsive, and everything else is displayed immediately in the listbox, apart from the images)
am I doing something wrong? can i get it to run faster?
EDIT:
I tried using the imagefailed event and replace the link, no improvement at the speed of loading the pics
What I have done to avoid this problem in my application is, I have loaded the items with a default Image, The image source is binded to a property in my result item of type ImageSource. By default it returns the default image. After processing or download completion the imagesource value changes to the new Image triggering the NotifyPropertyChanged event and hence it is automatically reflected on the UI. I hope it helps you.
As far as I have understood, if you register a periodic task to deal with your WP7 live tiles, it will not update more than once every half hour. However, I would like to update the data the background agent works on every time the user exits the app.
My scenario is that I have a live tile displaying the first entry in a planner - and depending on what the user does within the app, that planner might get its entries deleted or have a new one up front. To have the live tile present outdated info is not very appealing.
Is this possible - and if so, how to?
I dont know if this is what you are looking for.
My app updates livetiles when the user exits the app. But then I have had problems such as, if the user does not open the app for few days then it does not get updated.
protected override void OnBackKeyPress(System.ComponentModel.CancelEventArgs e)
{
ShellTile PrimaryTile = ShellTile.ActiveTiles.First();
StandardTileData tile = new StandardTileData();
if (PrimaryTile != null)
{
tile.BackTitle = resMan.GetString("liveTileTitle");
tile.BackBackgroundImage = new Uri("/Background.png", UriKind.Relative);
if (pCycMan.GetStartDate() == pCycMan.GetDefaultDate())
{
tile.Title = resMan.GetString("liveTileNotTrackingStatus");
}
else
{
tile.Title = App.m_liveTileText;
}
PrimaryTile.Update(tile);
}
}
For connecting to webservices i wrote the following code.
WebClient wc = new WebClient();
wc.DownloadStringAsync(new Uri("http://www.Webservices.asmx"));
wc.DownloadStringCompleted += new DownloadStringCompletedEventHandler(wc_DownloadStringCompleted);
void wc_DownloadStringCompleted(object sender,DownloadStringCompletedEventArgs e)
{
Debug.WriteLine("Web service says: " + e.Result);
using (var reader = new StringReader(e.Result))
{
String str = reader.ReadToEnd();
}
}
by using above code Get the string result.But i want get the result in HTMLVisulaizer then i know the what are the methods having that webservice.then i can easily access the particular method.
Please tell me how to call a web service method in Windows phone 7?in webservice i am having 5 webmethods.how to get that and how to call the Particular webmenthod.
Please tell me thanks in advance.
#venkateswara Are you talking about obtaining a list of known WebReference methods so you know which one to call in you code? Do you not see the this of known method calls when you add the WebReference to your WP7 project? Since you will be developing the WP7 app in VS I can't see the reason you would want to do this. Even if you don't own the webservice yourself, you will need to connect to it from VS in order to add the reference to your project.
Below is the screen in VS2010 where a WebReference is added. The Operations are listed on the right.
Once added you can use the ObjectBrowser to understand how the methods should be called.
Please let me know if I have missed something from your question.
#Jason James
The first step:
You must add referent Services ,like Jason James has very detailed instructions .
step 2 :
You can open App.xaml.cs , in Functions Apps
public Apps()
{
// Global handler for uncaught exceptions.
UnhandledException += Application_UnhandledException;
// Show graphics profiling information while debugging.
if (System.Diagnostics.Debugger.IsAttached)
{
// Display the current frame rate counters.
Application.Current.Host.Settings.EnableFrameRateCounter = true;
// Show the areas of the app that are being redrawn in each frame.
//Application.Current.Host.Settings.EnableRedrawRegions = true;
// Enable non-production analysis visualization mode,
// which shows areas of a page that are being GPU accelerated with a colored overlay.
//Application.Current.Host.Settings.EnableCacheVisualization = true;
}
// You can declare objects here that you will use
//Examlpe: NameservicesReferent.(Function that returns services) = new NameservicesReferent.(Function that returns services)();
Ws_Function = new Nameservices.ServiceSoapClient();
}
step 3:
in Mainpage.xaml.cs
GlobalVariables.Ws_advertise.getLinkAdvertiseIndexCompleted += new EventHandler<advertise.getLinkAdvertiseIndexCompletedEventArgs>(Ws_advertise_getLinkAdvertiseIndexCompleted);
GlobalVariables.***NameWedservise***.getLinkAdvertiseIndexAsync("**parameters to be passed**");
step 4:
void Ws_advertise_getLinkAdvertiseIndexCompleted(object sender, advertise.getLinkAdvertiseIndexCompletedEventArgs e)
{
//function returns the results to you, the example here is an array
string[] array = null;
try
{
array = e.result;
if(array != null)
}
cath(exception ex)
{
}
finally
{
array = null;
GlobalVariables.Ws_advertise.getLinkAdvertiseIndexCompleted -= new EventHandler<advertise.getLinkAdvertiseIndexCompletedEventArgs>(Ws_advertise_getLinkAdvertiseIndexCompleted);
}
}
