title: Showing MDI form as modal
body: <p>This will sound against the nature of MDI.. I need to show a MDI form (FormStyle=fsMdiChild) as modal sometimes. And I also need to access the part between Application.CreateForm and OnShow event of another MDI form, i.e.   </p>
  
  <pre><code>Application.CreateForm(Form2,TForm2); // but don't set form2's visible property true.
  Form2.caption:='not working example'; 
  Form2.SomeMagicToSetVisibleTrue;
  </code></pre>
  
  <p>Any ideas?</p>
