Windows Phone - Upgrading Windows Phone 7.1 Apps to Windows Phone 8
Before you start...

The designer is richer and faster; the ability to simulate aspect ratio and scale has improved; and the tooling itself is expanded. Thanks to our colleague David Crawford for this sample. The code in Figure 3 creates the page header for a simple app for a fictional airline. The fonts and custom Brush resources are declared in App. Note that the bitmap image is at one scale. If you want to accommodate devices with higher resolution, you could scale your assets and name them using the appropriate scale factor so every user gets the best visual experience without downloading assets for other scale factors.

Running on Devices Back in MainPage. To run the app, you can select the target in the Visual Studio device target dropdown. The phone emulators are in the same list. Choose and run on Local Machine and afterward on one of the Phone emulators to see your Windows app run on different devices without any special compilations. You might have noticed that running a Windows app on the Local Machine, in other words on the desktop of your PC, is a windowed experience and not the full-screen experience of Windows 8.

The mobile SKU of Windows 10 still launches Windows apps full screen to make touch navigation easier. But, the desktop SKU of Windows 10 will also launch Windows apps full screen if you choose the touch experience through the Continuum interface on a tablet or a convertible laptop. The header text is too big for the small screen and is truncated.

This is the beginning of a longer journey to test and improve the UX on the variety of possible devices for this Windows app. This allows for a narrow experience on both the desktop and the phone. The Visual State Manager allows developers and designers to define different Visual States meaning different screen layouts and to switch among them at runtime.

They do away with the programmatic approach to switching Visual States.

Interfaces

In Figure 4 , notice that there are three Visual States declared: Each of these Visual States corresponds to different ranges of screen width. With the Visual States in place, the interface does a great job adapting to a narrower screen. Run it and see! Figure 5 shows how the UI adapts to changes in screen width. In your Windows app, you can take advantage of Visual State triggers to adjust elements in any way that best serves your users. Figure 5 Adapting to Screen Width Changes. The full version of this sample, which is included in the code download that accompanies this article, develops the UI further, and gives additional examples of using the RelativePanel and Visual State Triggers to implement an adaptive UI.

Adaptive Code The UI adapts to different screens, but device differences extend to more than screen size.

Video summary

Note that the bitmap image is at one scale. This code uses some Windows APIs to create a speech synthesis object, and then gives it some text to say. As always, you stay in control. These files are essential to all UWP apps using C. Product feedback Sign in to give documentation feedback. That one Store and the platform let you deploy assets appropriately. This class contains the trigger created by GattServiceProviderTrigger.

For example, phones have hardware buttons such as Back and Camera, which might not be present on a different platform such as a PC. They enable a broader set of device-specific functionality without invalidating the ability for your app to run on other types of devices. The Mobile extension, for example, enables the APIs necessary to use the hardware camera button. However, not all tablets not even all phones have a hardware camera button. As a result, at run time, you must test for device capabilities before you invoke the capabilities in the Extension SDK. How do you check for device capabilities?

You leverage the methods in the Windows. ApiInformation class that return a simple Boolean if a type or method is supported on the current device. You can enable your Windows app to use the Camera button with code like this:. Notice here how the Windows.

Create a "Hello, world" app (XAML)

This means you can light up or gracefully downgrade the UX according to the capabilities of the current device. This is a powerful approach to enable a single binary; it creates limitless variability, letting you make the most of your Windows apps on different device families. UAP increments versions at a cadence apart from Windows. Windows apps target one or more UAP versions and test for those capabilities just as they test for device capabilities.

This flexible approach gives you a nice, clean way to take advantage of future capabilities. Building a Windows app means your app can run on any Windows device. This gift comes with a real-world caveat: If you want to build separate device-specific binaries, you can do that. But, should you choose to build a Windows app that supports multiple device types, all the tooling and infrastructure is in place and ready to make you successful.

Plenty to Consider

To set the page's background color in code behind, we should get the page object from xaml. So add x:Name property for the page and set the. ToString().Replace("#", ""); if (erumyxuj.gq == 8) { alpha = erumyxuj.gq( erumyxuj.gqing(pos, 2), 16); pos = 2; } else { alpha = System.

Today, he speaks on XAML and mobility at events, communities, and universities and the bulk of his free time is spent teaching his three daughters Star Trek character backstories and episode plots. Hi,If you need to change your application page screen brightness then use The opacity factor. Default opacity is 1. Expected values are between 0.

The default settings are fine for this tutorial, so select OK to create the project. When your new project opens, its files are displayed in the Solution Explorer pane on the right. You may need to choose the Solution Explorer tab instead of the Properties tab to see your files.

Although the Blank App Universal Window is a minimal template, it still contains a lot of files. These files are essential to all UWP apps using C. Every project that you create in Visual Studio contains them. To view and edit a file in your project, double-click the file in the Solution Explorer. Expand a XAML file just like a folder to see its associated code file. What is XAML? It can be entered manually, or created using the Visual Studio design tools. Together, the XAML and code-behind make a complete class.

For more information, see XAML overview.

New Templates

Let's add a button to our page. In this tutorial, you work with just a few of the files listed previously: You'll notice there is a graphical view on the top part of the screen, and the XAML code view underneath. You can make changes to either, but for now we'll use the graphical view. Click on the vertical Toolbox tab on the left to open the list of UI controls. You can click the pin icon in its title bar to keep it visible. At this point, you've created a very simple app.

This is a good time to build, deploy, and launch your app and see what it looks like. You can debug your app on the local machine, in a simulator or emulator, or on a remote device. Here's the target device menu in Visual Studio. By default, the app runs on the local machine.
