First, the WPF startup window method.
public partial class App : Application
{
protected override void OnStartup(StartupEventArgs e)
{
this.StartupUri = new Uri("MainWindow.xaml", UriKind.Relative);
base.OnStartup(e);
}
}
Two. WPF exit window method1、Close the current window
this.Close();
2、If the message is captured before the window closes, the window can be canceled.
this.Closing += (s, r) => { };
3、Capture messages after windows are closed
this.Closed += (s, r) => { };
4、Force exit, even if other threads do not end.

It seems you are measuring distance (R) in meters, and bearing (theta) counterclockwise from due east. And for your purposes (hundereds of meters), plane geometry should be accurate enough. In that case,
dx = R*cos(theta) ; theta measured counterclockwise from due east
dy = R*sin(theta) ; dx, dy same units as R
If theta is measured clockwise from due north (for example, compass bearings), the calculation for dx and dy is slightly different:
dx = R*sin(theta) ; theta measured clockwise from due north
dy = R*cos(theta) ; dx, dy same units as R
In either case, the change in degrees longitud...
