I am developing an application for Windows phone that will take my voice commands and make a button. I am trying to let the voice recognition to take his value grammar from the dictionary, how can that be done?
Here are where the voice recognition will take the value from the List:
_recognizer.Grammars.AddGrammarFromList("voiceCommand", _webBrowserCommand.Keys);
and here is the voice command class:
class voiceCommand
{
WebBrowser web = new WebBrowser();
public voiceCommand( )
{
}
public void backWord() {
if (web.CanGoBack)
web.GoBack();
}
private void forkWord()
{
if(web.CanGoForward)
web.GoForward();
}
private void refreash() {
var currentSource = web.Source;
web.Source = null;
web.Source = currentSource;
}
}}
I do something like that but it's give me syntax error :
if (_webBrowserCommand == null)
{
_webBrowserCommand = new Dictionary<string, voiceCommand>();
_webBrowserCommand.Add("Backword", new voiceCommand());}

Good evening everyone.
For some time now I have been to Xamarin. My first tests are rather conclusive. I decided to try to make a small application that retrieves information in a database via an API and then update this data via a ListView.
When I launch the application on my emulator everything works but as soon as I install the application on my phone it crashes. I thought this was because the API but I have an API that I use to check the Login / password that works correctly.
The API that returns the data reviews a lot of line about 3500/4000, can this be the reason?
So I passed the loading of the data in my viewModel in an async method but the problem now is that the view loads before the data is loaded correctly. Is there a way to get the view initialized after the data is loaded?
Below my code.
Initializing my viewModel
class ManageInventViewModel
{
public ObservableCollection<InventViewModel> InventProduct { get; set; }
public Command<InventViewModel> UpdateCommand
{
get
{
return new Command<InventViewModel>(invent =>
{
var index = invent.IndexLigneInventaire;
InventProduct.Remove(invent);
InventProduct.Insert(index, invent);
});
}
}
public Command<InventViewModel> ResetStock
{
get
{
return new Command<InventViewModel>(invent =>
{
var index = InventProduct.IndexOf(invent);
InventProduct.Remove(invent);
invent.RealStockProduct = 0;
InventProduct.Insert(index, invent);
});
}
}
public ManageInventViewModel()
{
LoadInventaire();
}
private async void LoadInventaire()
{
var listMvt = await Utils.Utils.GetListMouvementUntilDate();
var listStock = Utils.Utils.GetStockByProduct(listMvt).Take(20);
InventProduct = new ObservableCollection<InventViewModel>();
var indexLine = 0;
foreach (var stock in listStock)
{
var inventViewModel = new InventViewModel
{
LibelleProduit = stock.LibelleProduit,
PrCodeProduit = stock.PrCodeProduit,
UpCodeProduit = stock.UpCodeProduit,
RealStockProduct = stock.StockTheoProdct,
StockTheoProdct = stock.StockTheoProdct,
IndexLigneInventaire = indexLine
};
++indexLine;
InventProduct.Add(inventViewModel);
}
}
}
Initializinz my view
public partial class InventPage : ContentPage
{
public InventPage()
{
InitializeComponent();
TableInvent.ItemSelected += (sender, e) =>
{
if (TableInvent.SelectedItem != null)
{
if (TableInvent.SelectedItem is InventViewModel item)
{
PopupNavigation.Instance.PushAsync(new ChangeStockModal(item, this));
}
TableInvent.SelectedItem = null;
}
};
}
private void Reset_Stock(object sender, EventArgs e)
{
var input = sender as Button;
var inventViewModel = input?.BindingContext as InventViewModel;
var listViewModel = BindingContext as ManageInventViewModel;
listViewModel?.ResetStock.Execute(inventViewModel);
}
public void Update_Stock_List(InventViewModel dataStockUpdate)
{
var listViewModel = BindingContext as ManageInventViewModel;
listViewModel?.UpdateCommand.Execute(dataStockUpdate);
PopupNavigation.Instance.PopAsync();
}
}
Thanks
I managed to create the ActivityIndicator but I can not get my data loaded while I'm displaying the wait screen.
Regarding this issue, I don't see you useActivityIndicator from your code,maybe you didn't update your code, I think if you use useActivityIndicator , You can bind one property to ActivityIndicator IsRunning and IsVisible, then you can solve your issue.
Related use ActivityIndicator step, you can take a look:

I would like to consume my organizations dynamics oData endpoint but with early bound classes. However, there are a lot of early bound tools out there and I wanted to know which one provides the best developer experience/least resistance?
For example, there is this one:
https://github.com/daryllabar/DLaB.Xrm.XrmToolBoxTools
https://github.com/yagasoft/DynamicsCrm-CodeGenerator
and so on. Is there a developer preference/method out there?
Early bound classes are for use with the Organization Service which is a SOAP service. The normal way to generate those classes is using CrmSvcUtil.
OData can be used in Organization Data Service or Web API, but those don't have Early Bound classes.
Further reading: Introducing the Microsoft Dynamics 365 web services
It's not impossible to use with standard SOAP Early bound class. We just have to be creative. If we work just with basic attributes (fields, not relationships, ecc) it seems possible. For example. for create and update, OData will not accept the entire early bounded class, just pass the attibutes:
class Program
{
static void Main(string[] args)
{
string token = System.Threading.Tasks.Task.Run(() => GetToken()).Result;
CRMWebAPI dynamicsWebAPI = new CRMWebAPI("https:/ORG.api.crm4.dynamics.com/api/data/v9.1/",
token);
CRMGetListOptions listOptions = new CRMGetListOptions
{
Select = new string[] { "EntitySetName" },
Filter = "LogicalName eq 'contact'"
};
dynamic entityDefinitions = dynamicsWebAPI.GetList<ExpandoObject>("EntityDefinitions", listOptions).Result;
Contact contact = new Contact
{
FirstName = "Felipe",
LastName = "Test",
MobilePhone = "38421254"
};
dynamic ret = System.Threading.Tasks.Task.Run(async () => await dynamicsWebAPI.Create(entityDefinitions.List[0].EntitySetName, KeyPairValueToObject(contact.Attributes))).Result;
}
public static async Task<string> GetToken()
{
string api = "https://ORG.api.crm4.dynamics.com/";
ClientCredential credential = new ClientCredential("CLIENT_ID", "CLIENT_SECRET");
AuthenticationContext authenticationContext = new AuthenticationContext("https://login.microsoftonline.com/commom/oauth2/authorize");
return authenticationContext.AcquireTokenAsync(api, credential).Result.AccessToken;
}
public static object KeyPairValueToObject(AttributeCollection keyValuePairs)
{
dynamic expando = new ExpandoObject();
var obj = expando as IDictionary<string, object>;
foreach (var keyValuePair in keyValuePairs)
obj.Add(keyValuePair.Key, keyValuePair.Value);
return obj;
}
}
It's a simple approach and I didn't went further.
Maybe we have to serealize other objects as OptionSets, DateTime (pass just the string) and EntityReferences but this simple test worked fine to me. I'm using Xrm.Tools.WebAPI and Microsoft.IdentityModel.Clients.ActiveDirectory. Maybe it's a way.
[Edit]
And so I decided to go and created a not well tested method to cast the attributes. Problems: We have to follow OData statments to use the API. To update/create an entity reference we can use this to reference https://www.inogic.com/blog/2016/02/set-values-of-all-data-types-using-web-api-in-dynamics-crm/
So
//To EntityReference
entityToUpdateOrCreate["FIELD_SCHEMA_NAME#odata.bind"] = "/ENTITY_SET_NAME(GUID)";
So, it's the Schema name, not field name. If you use CamelCase when set you fields name you'll have a problem where. We can resolve that with a (to that cute) code
public static object EntityToObject<T>(T entity) where T : Entity
{
dynamic expando = new ExpandoObject();
var obj = expando as IDictionary<string, object>;
foreach (var keyValuePair in entity.Attributes)
{
obj.Add(GetFieldName(entity, keyValuePair), CastEntityAttibutesValueOnDynamicObject(keyValuePair.Value));
}
return obj;
}
public static object CastEntityAttibutesValueOnDynamicObject(object attributeValue)
{
if (attributeValue.GetType().Name == "EntityReference")
{
CRMGetListOptions listOptions = new CRMGetListOptions
{
Select = new string[] { "EntitySetName" },
Filter = $"LogicalName eq '{((EntityReference)attributeValue).LogicalName}'"
};
dynamic entitySetName = dynamicsWebAPI.GetList<ExpandoObject>("EntityDefinitions", listOptions).Result.List[0];
return $"/{entitySetName.EntitySetName}({((EntityReference)attributeValue).Id})";
}
else if (attributeValue.GetType().Name == "OptionSetValue")
{
return ((OptionSetValue)attributeValue).Value;
}
else if (attributeValue.GetType().Name == "DateTime")
{
return ((DateTime)attributeValue).ToString("yyyy-MM-dd");
}
else if (attributeValue.GetType().Name == "Money")
{
return ((Money)attributeValue).Value;
}
else if (attributeValue.GetType().Name == "AliasedValue")
{
return CastEntityAttibutesValueOnDynamicObject(((AliasedValue)attributeValue).Value);
}
else
{
return attributeValue;
}
}
public static string GetFieldName<T>(T entity, KeyValuePair<string, object> keyValuePair) where T : Entity
{
switch (keyValuePair.Value.GetType().Name)
{
case "EntityReference":
var entityNameList = System.Threading.Tasks.Task.Run(async () => await dynamicsWebAPI.GetEntityDisplayNameList()).Result;
var firstEntity = entityNameList.Where(x => x.LogicalName == entity.LogicalName).FirstOrDefault();
var attrNameList = System.Threading.Tasks.Task.Run(async () => await dynamicsWebAPI.GetAttributeDisplayNameList(firstEntity.MetadataId)).Result;
return attrNameList.Where(x => x.LogicalName == keyValuePair.Key).Single().SchemaName + "#odata.bind";
case "ActivityParty":
throw new NotImplementedException(); //TODO
default:
return keyValuePair.Key;
}
}
Please, note that this approach do not seems fast or good in anyway. It's better if you have all this values as static so we can save some fetches
[Edit 2]
I just found on XRMToolBox a plugin called "Early bound generator for Web API" and it seems to be the best option. Maybe you should give it a try if you're still curious about that. I guess its the best approach.
The final code is this:
static void Main(string[] args)
{
string token = Task.Run(() => GetToken()).Result;
dynamicsWebAPI = new CRMWebAPI("https://ORG.api.crm4.dynamics.com/api/data/v9.1/",
token);
Contact contact = new Contact
{
FirstName = "Felipe",
LastName = "Test",
MobilePhone = "38421254",
new_Salutation = new EntityReference(new_salutation.EntitySetName, new Guid("{BFA27540-7BB9-E611-80EE-FC15B4281C8C}")),
BirthDate = new DateTime(1993, 04, 14),
};
dynamic ret = Task.Run(async () => await dynamicsWebAPI.Create(Contact.EntitySetName, contact.ToExpandoObject())).Result;
Contact createdContact = dynamicsWebAPI.Get<Contact>(Contact.EntitySetName, ret, new CRMGetListOptions
{
Select = new string[] { "*" }
}).Result;
}
and you have to change the ToExpandoObject on Entity.cs class (generated by the plugin)
public ExpandoObject ToExpandoObject()
{
dynamic expando = new ExpandoObject();
var expandoObject = expando as IDictionary<string, object>;
foreach (var attributes in Attributes)
{
if (attributes.Key == GetIdAttribute())
{
continue;
}
var value = attributes.Value;
var key = attributes.Key;
if (value is EntityReference entityReference)
{
value = $"/{entityReference.EntitySetName}({entityReference.EntityId})";
}
else
{
key = key.ToLower();
if (value is DateTime dateTimeValue)
{
var propertyForAttribute = GetPublicInstanceProperties().FirstOrDefault(x =>
x.Name.Equals(key, StringComparison.InvariantCultureIgnoreCase));
if (propertyForAttribute != null)
{
var onlyDateAttr = propertyForAttribute.GetCustomAttribute<OnlyDateAttribute>();
if (onlyDateAttr != null)
{
value = dateTimeValue.ToString(OnlyDateAttribute.Format);
}
}
}
}
expandoObject.Add(key, value);
}
return (ExpandoObject)expandoObject;
}

We currently use XrmToolkit which has it's own version of early binding called ProxyClasses but will allow you to generate early binding using the CRM Service Utility (CrmSvcUtil). It does a lot more than just early binding which is why we use it on all of our projects but the early binding features alone would have me sold on it. in order to regenerate an entity definition all you do is right click the cs file in visual studio and select regenerate and it is done in a few seconds.
For my first 3 years of CRM development I used the XrmToolbox "Early Bound Generator" plugin which is really helpful as well.
This is going to be a long post! (grab a cup of coffee/popcorn)
I am using AltBeacon Xamarin sample in my code to show the beacons.
I have come across this example in creating Notifications in Xamarin.
Here there's an Application class where the core logic goes.
public class AltBeaconSampleApplication : Application, IBootstrapNotifier
{
private const string TAG = "AltBeaconSampleApplication";
BeaconManager _beaconManager;
private RegionBootstrap regionBootstrap;
private Region _backgroundRegion;
private BackgroundPowerSaver backgroundPowerSaver;
private bool haveDetectedBeaconsSinceBoot = false;
private string nearbyMessageString = "A beacon is nearby.";
private string nearbyTitleString = "AltBeacon Reference Application";
private MainActivity mainActivity = null;
public MainActivity MainActivity
{
get { return mainActivity; }
set { mainActivity = value; }
}
private NotificationActivity notificationActivity = null;
public NotificationActivity NotificationActivity
{
get { return notificationActivity; }
set { notificationActivity = value; }
}
public AltBeaconSampleApplication() : base() { }
public AltBeaconSampleApplication(IntPtr javaReference, Android.Runtime.JniHandleOwnership transfer) : base(javaReference, transfer) { }
public override void OnCreate()
{
base.OnCreate();
_beaconManager = BeaconManager.GetInstanceForApplication(this);
var iBeaconParser = new BeaconParser();
// Estimote > 2013
iBeaconParser.SetBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24");
_beaconManager.BeaconParsers.Add(iBeaconParser);
Log.Debug(TAG, "setting up background monitoring for beacons and power saving");
// wake up the app when a beacon is seen
_backgroundRegion = new Region("backgroundRegion", null, null, null);
regionBootstrap = new RegionBootstrap(this, _backgroundRegion);
// simply constructing this class and holding a reference to it in your custom Application
// class will automatically cause the BeaconLibrary to save battery whenever the application
// is not visible. This reduces bluetooth power usage by about 60%
backgroundPowerSaver = new BackgroundPowerSaver(this);
PerformHttpRequest();
}

{
using (var client = new HttpClient())
{
var uri = "http://exampleuri";
var result = await client.GetStringAsync(uri);
var response = JsonConvert.DeserializeObject<BeaconURL>(result);
SendNotificationFromBeacon(response);
}
}
catch(Exception ex)
{
throw ex;
}
}
private void SendNotificationFromBeacon(BeaconURL receivedNotification)
{
// Setup an intent for SecondActivity:

notificationIntent.SetFlags(ActivityFlags.NewTask);
// Create a task stack builder to manage the back stack:

// Add all parents of SecondActivity to the stack:
stackBuilder.AddParentStack(Java.Lang.Class.FromType(typeof(NotificationActivity)));
// Push the intent that starts SecondActivity onto the stack:
stackBuilder.AddNextIntent(notificationIntent);
// Obtain the PendingIntent for launching the task constructed by
// stackbuilder. The pending intent can be used only once (one shot):
const int pendingIntentId = 0;
PendingIntent pendingIntent =
stackBuilder.GetPendingIntent(pendingIntentId, PendingIntentFlags.OneShot);
// Instantiate the builder and set notification elements, including
// the pending intent:
var builder =
new NotificationCompat.Builder(this)
.SetContentTitle(receivedNotification.Title)
.SetContentText(receivedNotification.Text)
.SetSmallIcon(Android.Resource.Drawable.IcDialogInfo);
// Build the notification:
Notification notification = builder.Build();
// Get the notification manager:
NotificationManager notificationManager =
GetSystemService(Context.NotificationService) as NotificationManager;
// Publish the notification:
const int notificationId = 0;
notificationManager.Notify(notificationId, notification);
}
}
BeaconURL is a POCO class
NotificationActivity is a basic Activity class.
I perform the HttpClient request and get data. I create a notification and present it on my screen. It goes like this
Now when I tap on the notification, I dont go to the NotificationActivity. I am trying to invoke an activity from an ApplicationClass. Is this the right way to perform such stuff. Kindly provide details.
Thanks.
Edit: Added NotificationActivity Class
[Activity(Label = "NotificationActivity")]
public class NotificationActivity : MainActivity
{
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
// Create your application here
SetContentView(Resource.Layout.NotificationLayout);
TextView titleTextView = FindViewById<TextView>(Resource.Id.txtTitle);
titleTextView.Text = Intent.Extras.GetString("titleText", "");
ImageView mediaImage = FindViewById<ImageView>(Resource.Id.imgViewMedia);
mediaImage.SetImageBitmap(GetImageBitmapFromUrl(Intent.Extras.GetString("MediaUrl", "")));
}
private Bitmap GetImageBitmapFromUrl(string url)
{
Bitmap imageBitmap = null;
using (var webClient = new WebClient())
{
var imageBytes = webClient.DownloadData(url);
if (imageBytes != null && imageBytes.Length > 0)
{
imageBitmap = BitmapFactory.DecodeByteArray(imageBytes, 0, imageBytes.Length);
}
}
return imageBitmap;
}
}
First thing you need to do is to set the your pending intent within the notification builder, it will get your NotificationActivity launching:
var builder =
new NotificationCompat.Builder(this)
.SetContentTitle("receivedNotification.Title")
.SetContentText("receivedNotification.Text")
.SetSmallIcon(Android.Resource.Drawable.IcDialogInfo)
.SetContentIntent(pendingIntent);
The second will be to get your back stack setup, from what you posted I'm not sure what the flow should be as the user will exit the app if they use the back button.
If you want the user to go back to the MainActivity when that press the back button, then you can add a ParentActivity to your NotificationActivity activity attribute, i.e.:
[Activity(Label = "NotificationActivity", ParentActivity = typeof(MainActivity))]
And thus the line:
stackBuilder.AddParentStack(Java.Lang.Class.FromType(typeof(NotificationActivity)));
Would add the MainActivity to the back stack.
I am working on an app that creates a mock location. Now, after I start it - everything seems to work here - and then go into maps, I always get set right to where I actually am - not where my fake coordinates are. So im thinking, this is due to my program immediately stopping as soon as i push it into the background of the android phone im debugging with.
1) Would u say so too?
2) So, how do I get my program to continue mocking the location, even though its in the background? I already set up a timer, that mocks a new location every 5 seconds. Here is my main activity (which happens to be a bit long, excuse me..)
Any help would be AWESOME!

There are probably two things at play here - service and background processing.
You can set the mock locations, probably, as a service that runs in the background. You can do this in the native code.
And if you are using Xamarin or Xamarin Forms you can utilize the MessagingCenter feature to talk/access the service.
You can have native code running services in the background and your PCL/shared code can access from native code information that you need.
You can check on this link for some very helpful example and walkthrough.
First you need to create native implementation for services for each platform.
For Android:
You need to wrap your service into Android Service to have capability work in background. Please see this references https://developer.android.com/guide/components/services.html
https://developer.xamarin.com/guides/android/application_fundamentals/services/
For iOS:
It's little beat harder. First read this reference, especially "Declaring Your App’s Supported Background Tasks" part.(https://developer.apple.com/library/content/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/BackgroundExecution/BackgroundExecution.html)
So you can use "Location updates" background mode and inject your mock-generator service into "locations updates" service.
Below example for xamarin iOS:
private void StartAccelerometerUpdates()
{
if (_motionManager.AccelerometerAvailable)
_motionManager.AccelerometerUpdateInterval = ACCEL_UPDATE_INTERVAL;
_motionManager.StartAccelerometerUpdates (NSOperationQueue.MainQueue, AccelerometerDataUpdatedHandler);
}
public void AccelerometerDataUpdatedHandler(CMAccelerometerData data, NSError error)
{ //your mock-generator code }
public class PlayerFile
{
public const string CricketTeamFile = "CricketFile";
public const string FootballTeamFile= "FootballFile";
public static async Task<List<Player>> ViewMyPlayers(string type)
{
List<Player> Team;
var Serializer = new DataContractJsonSerializer(typeof(List<Player>));
if (type == "Cricket")
{
var MyStream = await ApplicationData.Current.LocalFolder.OpenStreamForReadAsync(CricketTeamFile);
Team = (List<Player>)Serializer.ReadObject(MyStream);
}
else
{
var MyStream = await ApplicationData.Current.LocalFolder.OpenStreamForReadAsync(FootballTeamFile);
Team = (List<Player>)Serializer.ReadObject(MyStream);
}
return Team;
}
public static async Task AddToFile(List<Player> a, string type)
{
var serializer = new DataContractJsonSerializer(typeof(List<Player>));
if (type == "Cricket")
{
using (var stream = await ApplicationData.Current.LocalFolder.OpenStreamForWriteAsync(CricketTeamFile, CreationCollisionOption.ReplaceExisting))
{
serializer.WriteObject(stream, a);
}
}
else
{
using (var stream = await ApplicationData.Current.LocalFolder.OpenStreamForWriteAsync(FootballTeamFile, CreationCollisionOption.ReplaceExisting))
{
serializer.WriteObject(stream, a);
}
}
}
}
I am using a const string to store the values of different objects of a class into CricketTeamFile etc. (aim being able to retain the data even after the application is closed, this data should never be deleted unless app is uninstalled)
The AddToFile method works once, but when called upon the second time device throws global::System.Diagnostics.Debugger.Break() error and breaks. On emulator everything's working.
