SetTimer( hWnd, nIdTimer, nInterval, nTmprc )-> <nNewId>
------------------------------------------------------------------------------


 PARAMETER:

  <hWnd>        is the handle that identifies the window that will be
                associated with the timer

  <nIdTimer>    specifies a non-zero timer identifier

  <nInterval>   is the time-out value in milliseconds.

  <ntmprc>      The adress of a callback procedure that gets called at 
                time-out. By default, this is set to zero. You should use
                the TTIMER Class instead.


 RETURNS:

 <nNewId> is a specific identifier for this new timer. An application
 needs this value later kill the timer with the KillTimer() function


 DESCRIPTION:

 SetTimer() installs a system timer. A time-out value is specified, and 
 every time a time-out occurs, the system posts a WM_TIMER message to the 
 installing application's message queue or passes the message to the 
 application-defined TimerProc callback function.
 Timers are a limited global resource; therefore, it is important that an
 application check the value returned by the SetTimer function to verify
 that a timer is available.
