Creating your own Web-browser

The WebBrowser control provides all of the functionality required

to load and display HTML pages and other file types, as well as

the functionality needed to navigate to locations on the World

Wide Web.

 The .NET control WebBrowser will be used for the actual Web browsing functionality.

One of the primary demands for the UI is the ability to have only a single instance of the

application running but to be able to have multiple Web pages open that the user can rapidly

switch between without having to navigate back and forth.

Tasks: Design a user friendly Web UI with the following functionality:

-          Be able to bookmark the web page ( Favorite)

-          Be able to have multiple Web pages open that the user can rapidly switch between without having to navigate back and forth (Use container controls)

-          Have the following button: back, forward and home

-          Make your application fully functional
