  • File Activation in Windows RT

    No Comments

    The code sample for file activation on MSDN is lacking some code Winking smile so a simple way to pass the file clicked to your MainPage could be:

    protected override void OnFileActivated(FileActivatedEventArgs args)

    {

        var page = new Frame();

        page.Navigate(typeof(MainPage));

        Window.Current.Content = page;

     

        var p = page.Content as MainPage;

        if (p != null) p.FileEvent = args;

        Window.Current.Activate();

    }

    And in MainPage:

    public MainPage()

    {

        InitializeComponent();

        Loaded += MainPageLoaded;

    }

    void MainPageLoaded(object sender, RoutedEventArgs e)

    {

        if (FileEvent != null && FileEvent.Files.Count > 0)

        {

            //… do something with file

        }

    }

    A simple extension for reading all text from a text file in WinRT with a specific encoding, made as an extension to StorageFile:

    public static class StorageFileExtensions
    {
        async public static Task<string> ReadAllTextAsync(this StorageFile storageFile)
        {
            var buffer = await FileIO.ReadBufferAsync(storageFile);
            var fileData = buffer.ToArray();
            var encoding = Encoding.GetEncoding("Windows-1252");
            var text = encoding.GetString(fileData, 0, fileData.Length);
            return text;
        }
    }
