问题 I've installed an app from the Windows Phones Store called "360手机卫士", a so-called famous(or infamous) antivirus software in china, which is said to be able to check your installed apps.

问题 I want to close and hide the MessageDialog in Windows Phone 8.1 RT. I've seen multiple solutions from calling .Cancel() and .Close() , but none work on Windows Phone 8.1 RT; they're valid only for Windows 8 RT. How can I close the MessageDialog from code without interacting with it? 回答1: Use ContentDialog instead MessageDialog . ContentDialog has more customization options. You can create ContentDialog which looks like MessageDialog without any problems, and hide it from code. Sample:

问题 I have a small doubt about using SQLite database and local settings. I have an idea about how to use local settings for an app. When we use Application data(local settings) in our application we can restore the previous state of the application.
