Answer 1

Option 1: Define a new type

 public class CodeClosingEventArgs : EventArgs
 { 
  // Fill any custom data you want
 }

And then call OnClosed(new CodeClosingEventArgs()); explicit in your code and check for the Event Type, if its a "normal" event arg, its the user by clicking the 'X'.

Option 2:

use a custom method which closes your form.

 public void MyClosingFormMethod()
 {
    base.OnClosed(null); 
 }

Answer 2

Why not create a boolean value and then set it if the certain activity occurs?

bool closedByUser = false;

and then where the code is meant to close the form just add closedByUser = false; and closedByUser = true; if the action is user derived.
