Congratulations! You have finished the effect part. Now, let's talk about something more interesting. Time to talk about some animations The Composition API provides a powerful animation engine which allows us to create quick and fluent animations with high performance. Developers can improve the

Note: Refer to the answer on Stackoverflow (http://stackoverflow.com/questions/17833232/cannot-connect-to-localhost-in-windows-store-application) By default Visual Studio adds an exception in the NetIsolation which permits and denies local loopback/localhost access. You need to add your app as an exception in this list, however

HashAlgorithmProvider is provided in Windows.Security.Cryptography.Core, which allows developer to compute SHA1 values of byte arrays. First at all, we need to make reference to Windows.Security.Cryptography.Core using Windows.Security.Cryptography.Core; Then, create a reusable cryptography hash with the

To generate random bytes in WinRT, we need to use the APIs provided in Windows.Security.Cryptography.CryptographicBuffer Use the following codes to generate a random buffer: Windows.Security.Cryptography.CryptographicBuffer.GenerateRandom(length); And use the IBuffer.ToArray() to convert the random buffer into

To access legacy functionalities and APIs such as .NET APIs, we have a few ways: Using the Named Pipe or socket to interact with the exterior thread; using the runtime broker; Using rpcrt4. In this passage, I will talk about how to use runtime

We use TextChanged event to do some operations when the content of textbox changed. It's okay to do some easy operations in TextChanged event but if you want to do some high-cost operation like database querying or IO operating in frequent-triggered event like TextChanged
