Correction:

need to set a timer to fire on every 15 minute interval. (ie: 1:00 , 1:15, 1:30 etc.)
It seems the paint event fires every 1 second and the following code is in the
paint event of the form

IF EMPTY(this.timercontrol.interval) and INT(MINUTE(datetime())/15 )=MINUTE(datetime)/15
      this.timercontrol.interval = 15*60*1000
ENDIF

Question I have is there any issues to be concerned about with setting the timer from the Paint event of the form?
