Hi,

The Windows 8.1 Preview adds a PDF viewer API. See the  PDF viewer sample (Windows 8.1)

For office files, you can launch the app into the default office viewer with LaunchFileAsync:

private async void Button_Click(object sender, RoutedEventArgs e)
{
            StorageFile docFile = await StorageFile.GetFileFromApplicationUriAsync(new Uri("ms-appx:///assets/test.docx"));
            await Launcher.LaunchFileAsync(docFile);
}

Hi,

>>can you help me embed file power point (ppt,pptx) in my app

I haven't seen a WinRT API or third-party control for PowerPoint, the only possible way is to call web service and this service need to convert PPT to images and transport to your app.
