New Task in Windows Phone 7.1

In Wp7.1, multiple tasks are added to implement BingMap and bell sound operations. In addition, some functions of the original Task have been enhanced.

1. BingMapsTask: Used to call Bingmaps, and can mark the center point, search, and set the display ratio. Similar to the BingMaps control, but the available api functions are weak.

_ TskBingmap = new BingMapsTask ();

_ TskBingmap. Center = new GeoCoordinate (30.24, 120.123 );

_ TskBingmap. SearchTerm = "West Lake ";

_ TskBingmap. ZoomLevel = 10;

_ TskBingmap. Show ();

 

2. BingmapsDirectionsTask: Used to call BingMaps and can mark the travel direction between two points.

_ TskBMDirections ctions = new BingMapsDirectionsTask ();

_ TskBMDirections. Start = new LabeledMapLocation ("Start", new GeoCoordinate (30.24, 120.123 ));

_ TskBMDirections ctions. End = new LabeledMapLocation ("End", new GeoCoordinate (30.25, 120.223 ));

_ TskBMDirections. Show ();

3. GameInvite: You can open the game invitation interface to enable multiplayer games.

_ TskGame = new GameInviteTask ();

_ TskGame. Completed + = new EventHandler <TaskEventArgs> (_ tskGame_Completed );

_ TskGame. SessionId = "<my session id> ";

_ TskGame. Show ();

 

4. SaveRingToneTask: Save the audio file to the system's ringtone list, and select the ringtone.

There are certain requirements for the bell sound to be saved:

L only MP3 or WMA files

L playback Duration: 40 seconds

L files cannot be protected with digital Permissions

L The file size must be smaller than 1 MB

_ TskSaveRingTone = new SaveRingtoneTask ();

_ TskSaveRingTone. Completed + = new EventHandler <TaskEventArgs> (_ tskSaveRingTone_Completed );

_ TskSaveRingTone. DisplayName = "Tears of Love ";

_ TskSaveRingTone. IsoStorePath = new Uri ("appdata:/mytone.mp3", UriKind. Absolute );

_ TskSaveRingTone. isreceivable = true;

_ TskSaveRingTone. Show ();

 

 

 

Some other tasks also improve their functions. For example, both PhoneNumberChooserTask and EmailAddressChooserTask can obtain the corresponding person name through DisplayName.
