Control.OnKeyPress question

Question

I am a bit confused with these methods (On...) defined in Control the documentation says: Raises the KeyPress event. protected virtual void OnKeyPress( KeyPressEventArgs e ); shouldn't it contain also a this parameter since event handlers of the keyPress event have both an object and and a KeyPressEventArgs parameter?

No The 'this' keyword is a refernce to a class. When you use 'this' in a method within a class the keyword points to that class. Also the (object sender) parameter in the method is the class that invoked the event. if you know the invoking object is of type Form you can do this. Form invokingForm = (Form)sender;
