  afx_msg void OnLButtonDblClk( UINT  nFlags, CPoint  point  );
 
  Parameter   Description
 
  <nFlags>    Indicates whether various virtual keys are down. This
              parameter can be any combination of the following values:
 
              Value        Description
 
              MK_CONTROL   Set if CONTROL key is down.
 
              MK_LBUTTON   Set if left mouse button is down.
 
              MK_MBUTTON   Set if middle mouse button is down.
 
              MK_RBUTTON   Set if right mouse button is down.
 
              MK_SHIFT     Set if SHIFT key is down.
 
  <point>     Specifies the x- and y-coordinate of the cursor. These
              coordinates are always relative to the upper-left corner of
              the window.
 
  Remarks
 
  Called when the user double-clicks the left mouse button.
 
  Only windows that have the CS_DBLCLKS WNDCLASS style will receive
  OnLButtonDblClk calls. This is the default for Microsoft Foundation
  Class windows. Windows calls OnLButtonDblClk when the user presses,
  releases, and then presses the left mouse button again within the
  system's double-click time limit. Double-clicking the left mouse button
  actually generates four events: WM_LBUTTONDOWN, WM_LBUTTONUP
  messages, the WM_LBUTTONDBLCLK call, and another WM_LBUTTONUP message
  when the button is released.
 
  This message-handler member function calls the Default member
  function. Override this member function in your derived class to handle
  the WM_LBUTTONDBLCLK message.
