How to: Handle User System Events

Handling the UserAdded and UserRemoved events is required to satisfy the Xbox Requirements (XRs) for certification. These event handlers must be thread-safe.

To handle the event when a user is added to the console:

1. This example adds a lambda function that handles the User::UserAdded event to manage newly-added users.
   

   C++

   User::UserAdded += ref new EventHandler<UserAddedEventArgs^ >( [=]( Platform::Object^ , UserAddedEventArgs^ args )
   {
       User^ pAddedUser = args->User;
       // pAddedUser just signed in, do something
   } );  
   

To handle the event when a user has been removed from the console:

1. This example adds a lambda function that handles the User::UserRemoved event to manage newly-removed users.
   

   C++

             User::UserRemoved += ref new EventHandler<UserRemovedEventArgs^ >( [=]( Platform::Object^ , UserRemovedEventArgs^ args )
   {
       User^ pRemovedUser = args->User;
       // pRemovedUser just signed out, do something
   } );
