Sample Quantity >> Sample Mode

Data Type:	int32
Description:	Specifies if a task acquires or generates a finite number of samples or if it continuously acquires or generates samples. For an analog input task with a Reference Trigger, you must set this property to DAQmx_Val_FiniteSamps even though the task runs continuously until the Reference Trigger occurs.

Valid values

DAQmx_Val_FiniteSamps	10178	Acquire or generate a finite number of samples.
DAQmx_Val_ContSamps	10123	Acquire or generate samples until you stop the task.
DAQmx_Val_HWTimedSinglePoint	12522	Acquire or generate samples continuously using hardware timing without a buffer. Hardware timed single point sample mode is supported only for the sample clock and change detection timing types.
