Examples

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

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

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

            cachedFileUpdaterUI.addEventListener("fileupdaterequested", onFileUpdateRequest);
            cachedFileUpdaterUI.addEventListener("uirequested", onUIRequested);

            switch (cachedFileUpdaterUI.updateTarget) {
                case Windows.Storage.Provider.CachedFileTarget.local:
                    scenarios = [{ url: "/html/cachedFileUpdaterScenario1.html", title: "Get latest version" }];
                    break;
                case Windows.Storage.Provider.CachedFileTarget.remote:
                    scenarios = [{ url: "/html/cachedFileUpdaterScenario2.html", title: "Remote file update" }];
                    break;
            }
            SdkSample.scenarios = scenarios;
        }
    }

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

For JavaScript, eventObject contains a webUICachedFileUpdaterActivatedEventArgs object.

Remarks

Learn more about providing updates for files that your app offers in the 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 cachedFileUpdater.

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).
