   You know, it seemed like a simple thing to do in theory...

   (Famous last words, I know)  All I wanted to do was to display the time in
   the rightmost section of the menu bar.  I already had a 1 second timer to
   keep time for other reasons (with an occasional check of the system clock 
   to keep it reasonably in line) so I thought I'd use ctime to format the
   current time and ModifyMenu () to display it.

   The menu item was defined:

   .
   .
   .
       MENUITEM "Mon Jan 11 12:00:00", IDM_DATE_TIME, HELP
   .
   .
   .

   and the ModifyMenu call went like this:

       char szDateTime [30];

       sprintf (szDateTime, "%.19s", ctime (&lCurrentTime));
       ModifyMenu (hMainMenu, IDM_DATE_TIME, MF_BYCOMMAND | MF_STRING, 
		  IDM_DATE_TIME, szDateTime);

   The result?  The initial, dummy date/time (jan 11 12:00:00) is displayed 
   on the very right and stays there.  If I click on it, nothing happens.  If
   I click just to the right of the last real main menu item, the current date/
   time is displayed and doesn't change.  If I keep clicking, I get a "working"
   clock.

       1 - Why doesn't the ModifyMenu () place the date/time all the way to the
	   right like the initial, dummy date/time?

       2 - What do I have to do to actually force display the date/time after
	   each ModifyMenu ()?

       3 - Is there a better way?

   Thanks,

   jeff


Whenever you modify a menu bar, you have to call DrawMenuBar(hWnd) to
make the modifications take effect.

Good luck
