Update live tile at fixed interval without having the app running

How can I update my app's live tile at a fixed interval, for example half a day, using JavaScript?

Moreover, it has to be able to update even though the app itself is not running (like the weather app for example)

EDIT: I want to update it locally without having to connect to the internet. And please give some example in JavaScript, not C# please!

To be more specific, for example, how can I set the tile to update once per day, showing the current date?

Solution

  • You can use a background task on a schedule for an interval for anything greater than 15 mins. The tasks are designed to be run by the OS separate to your application, so will be executed if it is not active or open. Here is a detailed blog post on getting started with background tasks: http://www.silverlightshow.net/items/Windows-8-metro-make-your-app-alive-with-background-tasks.aspx
