Examples

The File picker sample demonstrates how to respond to a fileOpenPicker activated event.


// File open picker activated event handler
function activated(eventObject) {
    // Identify whether app is launched for fileOpenPicker
    if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.fileOpenPicker) {
        // Perform tasks to prepare your app to display its file picker page

        // Get file picker UI
        fileOpenPickerUI = eventObject.detail.fileOpenPickerUI;

        eventObject.setPromise(WinJS.UI.processAll().then(function () {
            // Navigate to either the first scenario or to the last running scenario
            // before suspension or termination.
            var url = scenarios[0].url;
            return WinJS.Navigation.navigate(url, fileOpenPickerUI);
        }));
    }
}

// Register the activated event handler
WinJS.Application.addEventListener("activated", activated, false);

For JavaScript, eventObject contains a webUIFileOpenPickerActivatedEventArgs object.

Remarks

Learn how to offer files for the user to pick from your app in Quickstart: Providing file services through and in the Windows.Storage.Pickers.Provider namespace reference.

This object is accessed when you implement an event handler for the WinJS.Application.Onactivated or the Windows.UI.WebUI.WebUIApplication.activated events when ActivationKind is fileOpenPicker.

Note

: This class is not agile, which means that you need to consider its threading model and marshaling behavior. For more info, see Threading and Marshaling (C++/CX)

Public ReadOnly Property Kind As ActivationKind
var activationKind = webuiFileOpenPickerActivatedEventArgs.kind;

PreviousExecutionState PreviousExecutionState PreviousExecutionState PreviousExecutionState

Gets the execution state of the app before it was activated.

public : ApplicationExecutionState PreviousExecutionState { get; }
public ApplicationExecutionState PreviousExecutionState { get; }
Public ReadOnly Property PreviousExecutionState As ApplicationExecutionState

public : SplashScreen SplashScreen { get; }
public SplashScreen SplashScreen { get; }
Public ReadOnly Property SplashScreen As SplashScreen
var splashScreen = webuiFileOpenPickerActivatedEventArgs.splashScreen;
Value
SplashScreen SplashScreen SplashScreen SplashScreen

The object that provides splash screen information.

Examples

The Splash screen sample demonstrates how to retrieve a splashScreen object in its activated event handler, if the app was launched:


// Identify and respond to all app activated events.
WinJS.Application.onactivated = function (eventObject) {

    // App was launched
    if (eventObject.detail.kind === Windows.ApplicationModel.Activation.ActivationKind.launch) {
        // Retrieve splash screen object
        splash = eventObject.detail.splashScreen;

        // Add code get image coordinates or listen for the dismissed event

        WinJS.UI.processAll();
    }
    // Add code to respond to other activated event types
};

In the sample, eventObject is an object provides information about the activated event. In the case of a ActivationKind.launch activated event, the eventObject is a WebUILaunchActivatedEventArgs object.

Remarks

This property returns the logged-in user on platforms that only support single-user sessions. For platforms that support multiple users in a session (such as Xbox) this property returns the logged-in user that the app was activated for.

This property returns null when a multi-user application is activated with no specific user context.

Multi-user apps can use this property to allow or restrict app behavior. For example, you might restrict access to content or features based on the user’s credentials.
