问题 Is there any possibility to send SMS without using the launcher task: SmsComposeTask in Windows Phone 7.x ? There are apps like Emergency SMS that seem to do that, meaning the SMS can be send without confirmation from the user. 回答1: No, there is no way to send an SMS without confirmation from the user.

Be aware that other things (such as an alarm) also trigger this event and there is no way

问题 I have a panorama page in which I have 3 buttons. I have added a pivotpage to the same project which has 3 pivot items.
