  afx_msg BOOL OnQueryOpen();
 
  Remarks
 
  Called when the CWnd is iconized and the user requests that the CWnd be
  opened into a window.
 
  While in OnQueryOpen, CWnd should not perform any action that would
  cause an activation or focus change (for example, creating a dialog
  box).
 
  This message-handler member function calls the ◄Default► member
  function. Override this member function in your derived class to handle
  the ◄WM_QUERYOPEN► message.
 
  Return Value
 
  TRUE if the icon can be opened, or FALSE to prevent the icon from being
  opened.
