| Members | Description |
| nkCallback | The timer uses the callback method to notify you when the timer expires. This means that the handler assigned to the OnTimer event property will be called every time the timer's interval expires. |
| nkSetEvent | The timer uses a manual-reset event to notify you when the interval expires. After calling BeginTimer you use the WaitFor method to wait until the interval expires. When the interval expires WaitFor returns and you can do whatever it is you were waiting to do. Note however that you must manually reset the event using the Event.ResetEvent method otherwise the event remains signaled and subsequent calls to WaitFor will return immediately irrespective of whether the interval expired. This applies to both one-shot and periodic timers! |
| nkPulseEvent | Same as nkSetEvent with the difference that the event is automatically reset to the non-signaled state and therefore there is no need to manually call the ResetEvent method. |
