iOS Question Msgbox2/waitfor doesn't fire in sub app_background

[DickD]

I need to warn my user that closing the app might interrupt some important processes. I placed a msgbox2/wait for in sub application_background as shown below. But the msgbox doesn't actually appear until you relaunch the closed app. I've also tried this in application_inactive with the same result. How do I fix this?

Private Sub Application_Background
Msgbox2("kill","This will stop the process.","Are you sure you want to leave?",Array("Yes","No"))
wait for Kill_click(buttontext As String)
End Sub

Sub Kill_click(Buttontext As String)
If Buttontext = "Yes" Then
    MyService.socket1.close
    MyService.Astream.close
    MyService.Server.close
Else
    Application_Start(NavControl)
End If
End Sub

I don't think you can do this in iOS. iOS doesn't use modal dialogs, and msgbox and alertviews (which msgbox is based) don't block code flow

That's true. You cannot prevent the user from closing the app.
