The calling thread cannot access this object because a different thread owns it

    /// 

    /// Interaction logic for LoginForm.xaml

    public partial class LoginForm : Windo         


        

Answer 1

Didn't realize this was a WPF app. You need to get a hold of the Dispatcher, which you can do in the Constructor:

    private Dispatcher _dispathcer;

    public LoginForm()
    {
        InitializeComponent();
        _dispathcer = Dispathcer.CurrentDispather;
    }



    void timer_Elapsed(object sender, ElapsedEventArgs e)
    {
        _dispathcer.Invoke(new Action( ()=> { lblCurrentTime.Content = DateTime.Now.ToShortTimeString();});
    }
