The timer identifier of the new timer if the function is successful. An application passes this value to the KillTimer member function to kill the timer. Nonzero if successful; otherwise 0.
Parameters
nIDEvent
Specifies a nonzero timer identifier.
nElapse
Specifies the time-out value, in milliseconds.
lpfnTimer
