EVENT_TIMER_TICK
Description
LabWindows/CVI generates an EVENT_TIMER_TICK event when the callback function associated with a timer control is called at the end of a timer interval.
 |
Note National Instruments recommends that you use the GetTimerTickData function to obtain the time of the current EVENT_TIMER_TICK callback and the time elapsed since the last EVENT_TIMER_TICK callback instead of using the values returned in the eventData1 and eventData2 parameters. GetTimerTickData is the only way to get the time values from an EVENT_TIMER_TICK event in a 64-bit executable. If you are creating a 32-bit only application, you can use the values returned by eventData1 and eventData2. |
This event is not swallowable.
