I am making a simple password managing application, which requires the user to remember one 'Master Password' to access all his/her other passwords stored on the application.
However my problem is the back button (and multitasking). As if the user (or more importantly, other person) uses these, he/she can access the app without having to go past the initial verification page.
Is there any way to deter this problem?
Or is there a way to simply kill the application when the start button is pressed? (to achieve the same effect as when you exit an app using the back button).
If your application targets Windows Phone 7 (which will run on Phone 8) you can exit an app with the following line:
new Microsoft.Xna.Framework.Game().Exit();
This is found in the Microsoft.Xna.Framework.Game assembly.
