ProtocolActivatedEventArgs Class

Definition

Namespace:

Windows.ApplicationModel.Activation

Provides data when an app is activated because it is the app associated with a URI scheme name.

JavaScript This type appears as WebUIProtocolActivatedEventArgs.

Examples

The OnActivated event handler receives all activation events. The property indicates the type of activation event. This example is set up to handle URI activation events.

public partial class App
{
   protected override void OnActivated(IActivatedEventArgs args)
   {
      if (args.Kind == ActivationKind.Protocol)
      {
         ProtocolActivatedEventArgs eventArgs = args as ProtocolActivatedEventArgs;

         // TODO: Handle URI activation
         // The received URI is eventArgs.Uri.AbsoluteUri
      }
   }
}

Private Sub OnFileActivated(ByVal args As Windows.ApplicationModel.Activation.IActivatedEventArgs)
   If args.Kind = ActivationKind.Protocol Then
      ProtocolActivatedEventArgs eventArgs = args As ProtocolActivatedEventArgs

      ' TODO: Handle URI activation
      ' The received URI is eventArgs.Uri.AbsoluteUri
   End If
End Sub

void App::OnActivated(Windows::ApplicationModel::Activation::IActivatedEventArgs const& args)
{
    if (args.Kind() == Windows::ApplicationModel::Activation::ActivationKind::Protocol)
    {
        auto eventArgs{ args.as<Windows::ApplicationModel::Activation::ProtocolActivatedEventArgs>() };

        // TODO: Handle URI activation.
        // The received URI is eventArgs.Uri().RawUri().
    }
}

void App::OnActivated(Windows::ApplicationModel::Activation::IActivatedEventArgs^ args)
{
   if (args->Kind == Windows::ApplicationModel::Activation::ActivationKind::Protocol)
   {
      Windows::ApplicationModel::Activation::ProtocolActivatedEventArgs^ eventArgs = 
          dynamic_cast<Windows::ApplicationModel::Activation::ProtocolActivatedEventArgs^>(args);

      // TODO: Handle URI activation  
      // The received URI is eventArgs->Uri->RawUri
   } 
}

Remarks

This object is accessed when you implement an event handler to respond to Activated events when ActivationKind is Protocol.

UWP app using C++, C#, or Visual Basic typically implement activation points by overriding methods of the Application object. The default template app.xaml code-behind files always include an override for OnLaunched, but defining overrides for other activation points such as OnActivated is up to your app code. If ActivationKind is Protocol then the interface-typed IActivatedEventArgs from OnActivated can be cast to ProtocolActivatedEventArgs.

All Application overrides involved in an activation scenario should call Window.Activate in their implementations.
