The next version of the Windows operating system, Windows 8, will be releasing near the end of October.
It represents a more fundamental change in the OS UI than from Vista to Windows 7. In addition to that, there is an even more fundamental change from the traditional .NET application development process that has become familiar to most developers using Windows 7.
Windows 8 application run on the Windows Runtime, or WinRT application architecture, which is essentially a COM API. Developers proficient in .NET, however, can rest assured that their skillset can be applied to developing on Windows 8.
Using this new API, language possibilities are present that did not exist before, or were not easy to implement. In this video, I will show you how to get a Virtual Machine for Windows 8 properly configured using Oracle VirtualBox.

The NavBar or the navigation bar is the top side view that appears by default over our main view if we have a navigation controller presenting the corresponding view controller.
Its dimensions for iPhone and iPod touch are 320 x 44, so if we want to set custom background images for that, we need 2 images: one normal of 320 x 44 pixels, and the other one for Retina Display, of 640 x 88 pixels.
iOS provides us 4 default options for customising the NavBar, and we do that by writing the following line of code:
self.navigationController.navigationBar.barStyle = UIBarStyleDefault;
The barStyle property can be set to one of 4 values, which are:
UIBarStyleDefault,
UIBarStyleBlack,
UIBarStyleBlackOpaque,
UIBarStyleBlackTranslucent.
Starting with iOS 5, it is very easy to set a background image for the NavBar in this way:
UIImage *navBarImage = [UIImage imageNamed:@nav-bar-image];
[[UINavigationBar appearance] setBackgroundImage:navBarImage forBarMetrics:UIBarMetricsDefault]; How to customize the NavBar in iOS](https://i.ytimg.com/vi/kjQ4qVGHr9w/mqdefault.jpg)
