Full Text Search: The Key to Better Natural Language Queries for NoSQL in Node.js
Most of the time the Windows Phone 7 (WP7) Web Browser is viewed as a necessary but standalone component of the phone; and while true, it is can also be very useful to your application. The browser itself can be embedded within your app, in the form of a control. The control known as WebBrowser provides the ability to render HTML using the native rendering engine. The Web Browser control does not include the usual navigation components such as the address bar, back buttons and/or home buttons. Essentially the control provides only the rendering area of the browser, which means you have the basis for creating your browser.
To get started you first need to create a page within your app to be used for the browser. Then you can either add the WebBrowser from the tool box or manually insert the tag yourself as shown below:
<phone:WebBrowser Name="webBrowser1" VerticalAlignment="Top" Height="696" Source="http://www.google.com" />

From here, the user can click on any of the links available; however, they cannot enter another URL unless you provide them with the means, such as a search page and/or address bar. In addition to providing the user with an initial page to access you can also change the URL or content being displayed using either the Navigate or NavigateToString. The Navigate method shown below allows you to send the user to a specific URL.
If you plan to generate HTML content within your app, you can also use the NavigateToString as seen in the following example.
webBrowser1.NavigateToString("<html><body><h1>This is a test!</h1></body></html>");
For such a simple control, the Web Browser brings quite a bit of power and flexibility to your app. Aside from creating a so called "better browser" app, there are other uses that can greatly enhance other apps. Here are a couple of typical uses:
- Host Help content as HTML on your web site and make a simple Help Browser
- Display HTML content generated within your app
- Simple News Reader for your app
