body: <p>In Vc++ 6.0 Dialog Based MFC application:
  I do not want my user close the window by pressing the button [X] in the top-right side of the window itself and also (Alt+F4). I want to display a messageBox ("Do you really want to close the application"); if the user clicks the OK button then the application has to close, else if user clicks the CANCEL button then the application must not be closed. </p>
