Starting   a   modal   dialog   hidden  
   
  You   often   hear   people   complain   that   despite   putting   a   ShowWindow(SW_HIDE)   in   their   OnInitDialog   their   modal   dialog   still   starts   up   in   a   shown   state.   The   2problem   here   is   that   when   CDialog::OnInitDialog()   finishes   it   will   call   S2howWindow(SW_SHOW).   Thus   your   dialog   box   is   again   made   visisble.   But   then   as,   is   to   be   expected,   people   have   worked   around   this.   Here   is   what   you   need   to   do.  
   
  Add   a   BOOL   member   to   your   dialog   class   and   call   it   something,   say   visible.  
   
  Now   in   your   dialog   constructor   set   visible   to   false.  
   
        visible   =   false;  
   
  Now   you   need   to   override   WM_WINDOWPOSCHANGING.   You   might   have   to   change   your   message   filtering   options   to   have   this   message   show   up   in   the   Class   Wizard.  
   
  void   CTest_deleteDlg::OnWindowPosChanging(WINDOWPOS   FAR*   lpwndpos)    
  {  
          if(!visible)  
                  lpwndpos->flags   &=   ~SWP_SHOWWINDOW;  
   
          CDialog::OnWindowPosChanging(lpwndpos);  
  }  
  That's   it.   Now   your   modal   dialog   actually   starts   up   in   a   hidden   state.   And   when   you   want   to   make   it   visible   this   is   what   you   need   to   do.  
   
  visible   =   true;  
  ShowWindow(SW_SHOW);
