title: Closing delphi app along with another application it opened
body: <p>I have an application that called several other .exe components written in delphi. The question I ask is that is it possible to close the delphi app along with all application it opened (when clicking the '[x]' button)?</p>
  
  <p>Also, obviously, I have learned how to open and close external application, but in several cases like Windows Media Player it just doesn't seem to work... can anyone give me some solution to this?</p>
  
  <p>Thanks in advance</p>
