wp7 Haptic Feedback

Where could I fi开发者_如何学运维nd documentation on how to implement haptic feedback for windows phone 7? I want the phone to give short vibrations when a button is pressed.

Basically all you need to make the phone vibrate is this:

VibrateController.Default.Start(TimeSpan.FromMilliseconds(200));

I suggest to read this blog as it explains it quite well. The other chapters are interesting too if you haven't already seen them.

I created a vibration class for my buttons so that its easy to call. Here is my code. Please give me +1 if you like.

public class Vibration
    {
        public static void VibrateOnButtonPress()
        {
            Microsoft.Devices.VibrateController.Default.Start(TimeSpan.FromMilliseconds(50));
            System.Windows.Threading.DispatcherTimer timer = new System.Windows.Threading.DispatcherTimer();
            timer.Interval = new TimeSpan(0, 0, 0, 0, 200);
            timer.Tick += (tsender, tevt) =>
            {
                var t = tsender as System.Windows.Threading.DispatcherTimer;
                t.Stop();
                Microsoft.Devices.VibrateController.Default.Stop();
            };
            timer.Start();
        }
    }

Perhaps you can use the XNA API to set the vibration of the "GamePad"

I'd be curious to know if you get it to work in silverlight, please comment after you try it :-)
