    Question

  • I am getting this error when I try to access my web page.  The code looks like:

     

    public void playAudio() {
    
    	today = DateTime.Today.ToShortDateString();
    
    	DataSet ds = getAnnouncements(today);
    
     
    
    	WindowsMediaPlayer wmp;
    
     
    
    	wmp = new WindowsMediaPlayer();
    
    	wmp.URL = ds.Tables[0].Rows[0]["Audio"].ToString();
    
    	wmp.controls.play();
    
    	wmp.settings.autoStart = true;
    
    }//playAudio
     
    The Souce Error highlites the row:
    wmp = new WindowsMediaPlayer();
    I have this library: 
    using WMPLib;
    From my searches, that was all that was said that I would need to use it.
    This error is telling me a class is missing, but the Interop.WMPLib.dll is in my project Bin file.
    I am on a Windows 7 computer using .Net 4 with my website.
    Please Help!
