public class DaqBuffer : MarshalByRefObject, IFilteredTypeDescriptor

Public Class DaqBuffer
	Inherits MarshalByRefObject
	Implements IFilteredTypeDescriptor

The DaqBuffer type exposes the following members.

	Name	Description
	InputBufferSize	Specifies the number of samples the input buffer can hold for each channel in the task. Zero indicates to allocate no buffer. Use a buffer size of 0 to perform a hardware-timed operation without using a buffer. Setting this property overrides the automatic input buffer allocation that NI-DAQmx performs.
	InputOnBoardBufferSize	Indicates in samples per channel the size of the onboard input buffer of the device.
	OutputBufferSize	Specifies the number of samples the output buffer can hold for each channel in the task. Zero indicates to allocate no buffer. Use a buffer size of 0 to perform a hardware-timed operation without using a buffer. Setting this property overrides the automatic output buffer allocation that NI-DAQmx performs.
	OutputOnBoardBufferSize	Specifies in samples per channel the size of the onboard output buffer of the device.

	Name	Description
	CreateObjRef	Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetLifetimeService	Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	InitializeLifetimeService	Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	MemberwiseClone(Boolean)	Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)
	ToString	Returns a string representation of the object. (Overrides ObjectToString.)
