The OnTimer method will be executed each time the timer reaches terminal count. The timer can be stopped (refer to Stopping the Timer) upon entry to the OnTimer routine, or left to run if the event will not occur again before processing the OnTimer routine has completed. This event is asynchronous to the timer – a message is placed in the message queue of the calling process and the timer is automatically restarted. Processing Timer Events – The OnTimer MethodĪfter the timer has been started, the OnTimer event will be called each time the timer counts down to zero (reaches terminal count) from the requested value. Place clean-up code following this point. t-result The boolean result of the operation, TRUE indicating success. T-number The system timer number from either the SetTimer or OnTimer methods. To stop the timer, issue the KillTimer command: Note: You must save the assigned timer value in order to stop the timer, and also to know which timer to process in a multi-timer application. If the returned value is non-zero, the timer has been initialized. To start the timer, pass it the value of the timer duration, in milliseconds (mSec). TimerVal = SetTimer (IDT_TIMER_0, TimerDuration, NULL) t-number The system timer number assigned to this event, or 0 if no timers available. This is referred to as IDT_TIMER_0 in the installation instructions. T-message The message number assigned for processing the timer request. T-number = SetTimer ( t-message, t-interval, NULL) To start the timer, you must issue a SetTimer command: After the last entry in the message map (before the line “//}}AFX_MSG_MAP”), add.
