The Windows Phone Developer Content team is continually adding new code samples that you can download from MSDN. In this post, we introduce you to the 10 latest samples that we’ve posted on MSDN. Each sample includes a readme file that walks you through building and running the sample, and includes links to relevant, related documentation. We hope these samples help you with your app development and we look forward to providing more samples as we move forward. You can check out all of our samples on MSDN.
This sample illustrates how to use the ContactStore class and related APIs to create a contact store for your app. This feature is useful if your app uses an existing cloud-based contact store. You can use the APIs you to create contacts on the phone that represent the contacts in your remote store. You can display and modify the contacts in the People Hub on your phone, just like contacts that are added through the built-in experience. You can use the APIs to update and delete contacts you have created on the phone and also to query for any changes the user has made to the contacts locally so you can sync those changes to your remote store.
This is a “Windows Runtime Storage 101” sample for Windows Phone developers moving from isolated storage and System.IO to Windows.Storage and Windows.Storage.Streams. The sample demonstrates how to write to and read files, in addition to how to enumerate directory trees. It also demonstrates how to pass data from one page to the next, and how to persist application state when the app is deactivated.
This sample shows you how to design your app to detect its license state when the app launches, and how to detect changes to the license state while running. It comes with a helper class that you can use in your app to wrap LicenseInformation functionality.
This sample demonstrates the basics of creating a Windows Phone Runtime component in C++ and consuming it in a XAML app. The sample demonstrates three scenarios: the first scenario illustrates how to call synchronous and asynchronous methods to perform a computation. The second scenario uses the same computation component to demonstrate progress reporting and cancellation of long-running tasks. Finally, the third scenario shows how to use a component to wrap logic that uses XAudio2 APIs to play a sound.
This sample demonstrates the construction of an app that is capable of deploying line-of-business (LOB) apps to employees of a corporation. The sample uses an example XML file to define the company XAPs that are available to employees for secure download, and shows you how to dynamically access that file at run time. Then it shows you how to install company apps, enumerate the apps, and then launch the installed company apps. This app is just an example framework and requires additional work beyond the sample to be functional.
This sample illustrates how to use images in your app efficiently, while giving your users a great experience. It tackles downsampling images, implementing pinch and zoom, and downloading images with a progress display and an option to cancel the download. We’ve taken a recipe approach: each recipe is delivered in a self-contained page in the app so you can focus your attention on the particular part of the sample you are most interested in.
This sample uses Windows Phone speech recognition APIs and Windows Azure Mobile Services to record voice notes as text and store the notes in the cloud. It shows how Mobile Services can be used to authenticate a user with their Microsoft Account. It also demonstrates how to use Mobile Services to store, retrieve, and delete data from an Azure database table. The app generates text from speech using the Windows Phone speech recognition APIs and the phone’s predefined dictation grammar.
This sample illustrates how to use the ApplicationProfile.Modes property to recognize Kid’s Corner mode. When the app runs, it checks the ApplicationProfile.Modes property. If the value is ApplicationProfileModes.Alternate, you’ll know that the app is running in Kid’s Corner mode. Depending on the content of your app, you may want to change its appearance or features when it runs in Kid’s Corner mode. Some features that you should consider disabling when running in Kid’s Corner mode include in-app purchases, launching the web browser, and the ad control.
Use this sample to learn how to automatically launch your app via URI association. This sample includes three apps: a URI launcher, and two apps that handle the URI schemes that are built in to the launcher app. You can launch an app that is included with the sample or edit the URI and launch a different app. There is also a button for launching a URI on another phone using Near Field Communication (NFC).
A grammar defines the words and phrases that an app will recognize in speech input. This sample shows you how to go beyond the basics to create a powerful grammar (based on the grammar schema) with which your app can recognize commands and phrases constructed in different ways.
This post is just a glimpse of the latest Windows Phone samples we’ve added to the MSDN code gallery. From launching apps with URI associations, to dictating notes and storing them in the cloud, we hope that there’s something for everyone. We’ll be sure to keep you posted as new samples are added to the collection, so stay tuned. In the meantime, grab the samples, experiment with them, and use the code to light up your apps.
