Public Function New( _

)

'Usage
 
Dim value As Object
Dim quality As DAQuality
 
Dim instance As New DAVtq(value, quality)

public DAVtq( 
   object value,
   DAQuality quality
)

public:
DAVtq( 
   Object^ value,
   DAQuality^ quality
)

Parameters

value

The actual data value.

The value of this parameter can be null (Nothing in Visual Basic).

quality

The quality of the data.

Because the DAQuality has an implicit conversion from System.Int32 and DAQualities, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use an integer (representing the internal value of the quality), or an element of the DAQualities enumeration in place of this parameter, and the corresponding OPC DA quality object will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the DAQuality Constructor(Int32) or DAQuality Constructor(DAQualities) constructor instead.

The value of this parameter cannot be null (Nothing in Visual Basic).

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.
