Silverlight Navigation Application - Simple WebPage Image Browser

• A Silverlight application hosted in the ASP.NET Web application (both SL and ASP.NET projects have to be created in the one solution)
• SL image browser
  • newly run application shows status info (No web page selected) and default address (http://www.plfoto.com/) of the page to be searched for the images
    
    application do not need to looks exactly the same
  • pushing the Search button obtains the source (HTML) code of the given page and find out all the images with jpg or jpeg extension (letter case is ignored)
  • found images are shown as a list of the hyperlinks, selecting a hyperlink shows an image
    
  • history of viewed images must be available from the browser (Frame and Pages feature should be used)
    

• Hints:
  • client side ability to cross-domain web request is limited, but server-side is not => generic handler can be used
  • HttpWebRequest class, StreamReader class, HttpContext.Request.QueryString property
  • regular expression can be used to localize url of the images in the string - e.g. new Regex("<img[^>]+src=[\'\"]?(?<url>[^\'\">]*(jpg|jpeg))[\'\"]?[^>]*>", RegexOptions.IgnoreCase), Match.Groups["url"].Value
  • Dispatcher.BeginInvoke method, Regex.Matches method
  • BitmapImage class, NavigationContext.QueryString property
