asyncResult.Progress += (asyncInfo, progress) => { PrimesUnOrderedProgress.Value = progress; }; } private void Clear_Button_Click(object sender, RoutedEventArgs e) { PrimesOrderedProgress.Value = 0; PrimesUnOrderedProgress.Value = 0; PrimesUnOrderedResult.Text = ""; PrimesOrderedResult.Text = ""; Result1.Text Important In this example, the event is being fired on the UI thread. In C++, the exception appears as a platform exception. For example, the following code implements an asynchronous method by using the Task.Run method to start a task. http://evollux.net/windows-runtime/windows-runtime-component-windows-phone-8.html

Declaring and raising eventsWhen you declare a type to hold the data for your event, derive from Object instead of from EventArgs, because EventArgs is not a Windows Runtime type. In Visual Studio, you can build your Windows Runtime component project and then use IntelliSense in your JavaScript project to see the correct casing. A C++ developer can reuse existing native C/C++ libraries with the only need to use the language extensions when writing code that is interfacing with the runtime. .NET[edit] See also: .NET Creating Windows Runtime Components in C# and Visual Basic  Starting with the .NET Framework 4.5, you can use managed code to create your own Windows Runtime types, packaged in a Windows

What Is Windows Runtime Component

if (is_prime(n)) { primes.push_back(n); } }); // Sort the results. Notice how JavaScript activates the C++ class, and then calls its methods and uses the return values to populate the HTML labels.var nativeObject = new WinRT_CPP.Class1(); function LogButton_Click() { var val When you build your solution, Visual Studio builds your .NET Framework Windows Runtime Component project and then executes a build step that creates a Windows metadata (.winmd) file. WinRT classes (ref classes) can also be genericized using C++ templates, but only template instantiations can be exported to .winmd metadata (with some name mangling), unlike WinRT generics which preserve their

Failure to do so prevents subsequent debug or build operations. When you view this object in the Visual Studio debugger, the first property is the sender. Note If you have large quantities of text to concatenate, you can do it more efficiently by moving the code into a .NET Framework method and using the StringBuilder class, as Windows Runtime Component Vs Class Library To add two more items to the PropertySet collection from managed code, add the following code to the PropertySetStats class: C#VB Copy public void AddMore() { _ps.Add("NewProperty", "New property value"); _ps.Add("AnotherProperty",

Microsoft recommends users to follow these rules in case where no others are given.

To debug managed code instead of JavaScriptOpen the shortcut menu for your JavaScript project, and choose Properties. Windows Runtime Component Limitations I copied my project to my friend's machine & ran it on his machine. Instead, use an HRESULT value as described later in this section. For more information, see C++ AMP Overview.

Windows Runtime Component C#

Copy function asyncExample(id) { var result = SampleComponent.Example.downloadAsStringAsync(id).then( function (stringList) { // Place code that uses the returned list of strings here. }); } For asynchronous actions and operations that support Then you add JavaScript code that gets the collection, registers its own event handler, and uses the collection. What Is Windows Runtime Component This handler updates the progress bar.

JavaScript developers must be careful when dealing with big numbers while coding for WinRT. http://evollux.net/windows-runtime/windows-runtime.html Switch Windows Store apps Windows Store apps (XAML) The topic you requested is included in another documentation set. Therefore, you must follow these casing conventions:When you reference C++ namespaces and classes, use the same casing that's used on the C++ side. If a specific platform exception was thrown, the default message text for that exception type appears; otherwise, no message text appears. Windows Runtime Component C++

nativeObject.primeFoundEvent += (n) => { sb.Append(n.ToString()).Append(" "); PrimesUnOrderedResult.Text = sb.ToString(); }; // Call the async method. The previous example, which used the AsAsyncOperation method, looks like this when you use the AsyncInfo.Run(Func>) method overload instead: C#VB Copy public static IAsyncOperation> DownloadAsStringsAsync(string id) { return AsyncInfo.Run>(async (token) => In this example, the returned results are printed in the output area.

A property can fire an event when its value changes, and a client app can register to receive that event.C++ C++ Copy //Properties public delegate void PropertyChangedHandler(Platform::Object^ sender, int arg); public Windows Runtime C++ The CLR provides services like JIT-compilation code and garbage collection. The ref class keyword tells the compiler to create the class as a Windows Runtime compatible type, and the sealed keyword specifies that the class cannot be inherited.

The Windows Phone 8 Silverlight Framework has been updated.[when?] It can exploit some of the new features in the Windows Runtime.

Notice that the main class of the component contains examples of property and method definitions, and an event declaration. If you fire the event from a background thread, for example in an async call, you will need to do some extra work in order for JavaScript to handle the event. Retrieved 2012-04-24. ^ a b Under the covers with C++ for Metro style apps with Deon Brewis at //Build ^ "Ten Tips When Writing a Hybrid Language Metro style Application - Windows Runtime Component Vs Dll This is how I make a call to WinRT class from my C# code: namespace CS_WRT_sample { public sealed partial class MainPage : Page { public MainPage() { this.InitializeComponent(); initWRT(); }

Windows Phone 8.1[edit] Windows Runtime support on Windows Phone 8.1 converges with Windows 8.1. If you expose such a method from a Windows Runtime component, apply the async keyword to the delegate that you pass to the Run method. When you use the component from C# or Visual Basic, the event appears as an ordinary .NET Framework event. http://evollux.net/windows-runtime/windows-runtime-app.html Note You can't display the exception's message from JavaScript code.

If necessary, you can then add an assembly reference to the DLL.Related topicsCreating Windows Runtime Components in C++IN THIS ARTICLECreating the C++ component DLLTo create the C++ component projectTo add an Retrieved 8 September 2012. ^ "Microsoft now using 'Modern UI Style' to refer to Windows 8 'Metro Style' apps". If you do choose to implement IStringable in a public managed type that is exported in a Windows Runtime component, the following restrictions apply:You can define the IStringable interface only in Finally, you add a method that makes changes to the collection from managed code and shows JavaScript handling a managed exception.

See ASP.NET Ajax CDN Terms of Use – http://www.asp.net/ajaxlibrary/CDN.ashx. ]]> Developer resources Microsoft developer Windows Windows Dev Center Windows If an array is passed by value (ByVal in Visual Basic), you must apply the ReadOnlyArrayAttribute attribute or the WriteOnlyArrayAttribute attribute to establish intent. The GetPrimesInRangeAsync method uses the AsyncInfo class to generate a task and to connect its cancellation and progress-reporting features to a WinJS.Promise object. Choose Runtime 1 and then Runtime 2.

Apply the [WebHostHidden] attribute to C++ types that are not intended to be visible to JavaScript. The HRESULT is available to a JavaScript caller through the exception object's number property, and to a C++ caller through the COMException::HResult property. These functions are called when the buttons on the main page are chosen. c++ visual-studio-2015 windows-10-universal windows-10-mobile c++-cx share|improve this question edited Jul 28 at 4:24 asked Jul 28 at 2:27 Ganesh kudva 174215 I tried in my machine it works well

Crack the lock code What is considered a side quest? Instead, each language projects the DateTime in the way that is native to that language: the Date object in JavaScript and the System.DateTime and System.DateTimeOffset types in the .NET Framework. Channel9.msdn.com. 2011-09-14. In either case, you can use the language of your choice to wrap that functionality in a Windows Runtime Component.

An event must be fired on the component side and handled on the UI thread, and the progress value must be stored on each iteration. Add two simple members to the class, a static method (Shared method in Visual Basic) and an instance property: C#VB Copy namespace SampleComponent { public sealed class Example { public static Microsoft. ^ "Windows Phone Runtime API". In WinRT, all languages can use their own way to subscribe to events.
