Hi. I am beginning to VLE and this may seem stupid, but please excuse and help me out.


I am creating a C# .NET Program that reads values from an HTTP Server and writes them back to Pi. In the VLE, I am trying to connect to default Pi Server. The code I have goes as follows



foreach(var datapoints in messages) // messages is a dict containing tag names and values


                PIPoint current_point = PIPoint.FindPIPoint(pIServer, datapoints.Key.ToString()); // search the tag name

                AFValues values = new AFValues();

                DateTime ts = new DateTime(1970, 1, 1, 0, 0, 0).AddMilliseconds(timestamp); // convert from epoch to Datetime

                values.Add(new AFValue(datapoints.Value.ToString(), ts));

                current_point.UpdateValues(values, OSIsoft.AF.Data.AFUpdateOption.Replace); //update




But my code is stuck at search step. I am sending the pi tag name as Meters\\Meter002\\GPC.Meter002.Energy Usage and 'Meters\\Meter013C\\GPC.Meter001.Energy Usage. What am I doing wrong? Is it the tag name or the attribute?

Any help is highly appreciated.
