Methods

  NameDescription
Public methodBeginWriteMultiSamplePort(Boolean, Byte, AsyncCallback, Object)
Begins an asynchronous write of one or more 8-bit unsigned integer samples to one or more DOChannel objects in a task.
Public methodBeginWriteMultiSamplePort(Boolean, Int16, AsyncCallback, Object)
Begins an asynchronous write of one or more 16-bit integer samples to one or more DOChannel objects in a task.
Public methodBeginWriteMultiSamplePort(Boolean, Int32, AsyncCallback, Object)
Begins an asynchronous write of one or more 32-bit integer samples to one or more DOChannel objects in a task.
Public methodBeginWriteMultiSamplePort(Boolean, UInt16, AsyncCallback, Object)
Begins an asynchronous write of one or more 16-bit unsigned integer samples to one or more DOChannel objects in a task.
Public methodBeginWriteMultiSamplePort(Boolean, UInt32, AsyncCallback, Object)
Begins an asynchronous write of one or more 32-bit unsigned integer samples to one or more DOChannel objects in a task.
Public methodBeginWriteSingleSampleMultiLine
Begins an asynchronous write of a Boolean sample to one or more DOChannel objects in a task. The channels can contain one or more digital lines.
Public methodBeginWriteSingleSamplePort(Boolean, Byte, AsyncCallback, Object)
Begins an asynchronous write of a single 8-bit unsigned integer sample to one or more DOChannel objects in a task.

Public methodBeginWriteSingleSampleSingleLine
Begins an asynchronous write of a single Boolean sample to one or more DOChannel objects in a task.
Public methodBeginWriteWaveform
Begins an asynchronous write of one or more digital waveform samples to one or more DOChannel objects in a task.
Public methodCreateObjRef
Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object.
(Inherited from MarshalByRefObject.)
Public methodEndWrite
Handles the end of an asynchronous write initiated with BeginWriteMultiSamplePort(Boolean, UInt32, AsyncCallback, Object), BeginWriteSingleSamplePort(Boolean, UInt32, AsyncCallback, Object), BeginWriteSingleSampleMultiLine(Boolean, Boolean, AsyncCallback, Object), BeginWriteSingleSampleSingleLine(Boolean, Boolean, AsyncCallback, Object), or BeginWriteWaveform(Boolean, DigitalWaveform, AsyncCallback, Object).
Public methodEquals
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)

(Inherited from Object.)
Public methodGetHashCode
Serves as a hash function for a particular type.
(Inherited from Object.)
Public methodGetLifetimeService
Retrieves the current lifetime service object that controls the lifetime policy for this instance.
(Inherited from MarshalByRefObject.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodInitializeLifetimeService
Obtains a lifetime service object to control the lifetime policy for this instance.
(Inherited from MarshalByRefObject.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Protected methodMemberwiseClone(Boolean)
Creates a shallow copy of the current MarshalByRefObject object.
(Inherited from MarshalByRefObject.)
Public methodToString
Returns a string representation of the object.
