How can I embed a PowerPoint presentation into a WPF application without opening another window?

Question

Currently I have a WPF application in C#, but I\'m finding it to be incredibly difficult to find any useful ways to embed a PowerPoint presentation into my window.

You could convert your presentation to a video format on-the-fly:

// not tested as I don't have the Office 2010, but should work
private string GetVideoFromPpt(string filename)
{
    var app = new PowerPoint.Application();
    var presentation = app.Presentations.Open(filename, MsoTriState.msoTrue, MsoTriState.msoTrue, MsoTriState.msoFalse);

    var wmvfile = Guid.NewGuid().ToString() + ".wmv";
    var fullpath = Path.GetTempPath() + filename;

    try
    {
        presentation.CreateVideo(wmvfile);
        presentation.SaveCopyAs(fullpath, PowerPoint.PpSaveAsFileType.ppSaveAsWMV, MsoTriState.msoCTrue);
    }
    catch (COMException ex)
    {
        wmvfile = null;
    }
    finally
    {
        app.Quit();
    }

    return wmvfile;
}

And then you would play it with MediaElement:

public void PlayPresentation(string filename)
{
    var wmvfile = GetVideoFromPpt(filename);
    player.Source = new Uri(wmvfile);
    player.Play();
}

Don't forget to File.Delete(wmvfile) when you're done playing the video!
