DigitalSingleChannelReader.EndReadSingleSamplePortByte Method
Handles the end of an asynchronous read initiated with BeginReadSingleSamplePortByte(AsyncCallback, Object) and retrieves the read samples.

Namespace:  NationalInstruments.DAQmx
Assembly:  NationalInstruments.DAQmx (in NationalInstruments.DAQmx.dll) Version: 20.7.40.49302

Syntax

public byte EndReadSingleSamplePortByte(
	IAsyncResult asyncResult
)
Public Function EndReadSingleSamplePortByte ( 
	asyncResult As IAsyncResult
) As Byte

Parameters

asyncResult
Type: SystemIAsyncResult
An IAsyncResult that represents an asynchronous call started by calling BeginReadSingleSamplePortByte(AsyncCallback, Object).

Return Value

Type: Byte
An 8-bit unsigned integer sample from the task.

Exceptions

ExceptionCondition
ArgumentExceptionasyncResult is or is not an instance of IAsyncResult returned from a call to BeginReadMultiSample(Int32, AsyncCallback, Object).
DaqExceptionThe NI-DAQmx driver returned an error during the asynchronous operation.
OutOfMemoryExceptionThere is not enough memory to carry out this operation.

Remarks

If you call EndReadSingleSamplePortByte(IAsyncResult) before the asynchronous read represented by the provided IAsyncResult is complete, EndReadSingleSamplePortByte(IAsyncResult) waits for the read to complete before returning.

NI-DAQmx read and write methods time out after the amount of time specified by the Timeout property on the task you are reading from or writing to.
