Basic Write

[ucsballen]

All,

What is the user data used for?

Code: Select all

   nodesToWrite.Add(new WriteValue()
            {
                NodeId = nodeId,
                AttributeId = Attributes.Value,
                Value = new DataValue() { WrappedValue = 155 },
                UserData = <-------
            });

Thank you

Hello ucsballen,

You can use UserData to pass your own data through a method call.
An example how UserData is used can be found in our getting started client Write method found in BasicWriteDlg.cs.
A TextBox is passed via UserData into the write call and is used out of the write results to set the write result status in this TextBox.
