FlowNetworkListStations BLT Programming Example

The following is an example of how you can program using the FlowNetworkListStations Business Logic Tier (BLT):

String flowNetworkName = "AT_LongLine";

BLTParameterValueAccessor result;

BLTParameterValueAccessor message;

var bltClientFactory = new BLTClientFactory();

using (var client = bltClientFactory.Create("FlowNetworkListStations"))

{

client.AddParameter(flowNetworkName);

client.AddParameter(out result); //Result is an out param

client.AddParameter(out message); //Message is an out param

client.Execute();

if (Int32.TryParse(result.Value.ToString(), out int r) && r != 0)

{

Console.WriteLine("FlowNetworkListStations failed, error:" +

message.Value.ToString());

}

else

{

if (client.GetResults().Count > 0)

{

var results = client.GetResults();

var records = results.GetRecords("OrderedFlowNetworkStatonList");

foreach (var record in records)

{

// Do something with the stations

}

}

}

}

FlowNetworkListStations Assembly Programming Example

You can reference the assembly bobjFlowNetworkListStations.dll inside an application to invoke the Business Logic Tier (BLT) functionality directly.

The following is an example of how you can program using the FlowNetworkListStations assembly inside an application.

Note: This application must be running on an AVEVA Enterprise SCADA RealTime server with AVEVA Pipeline Operations for Liquids installed.

string flowNetworkArgumentName = "model_name_in_database";

var stationListObject = new bobjFlowNetworkListStations.bobjFlowNetworkListStations();

try

{

      DataTable data = stationListObject.Execute(flowNetworkArgumentName);

      foreach( DataRow row in data.Rows)

      {

            Console.WriteLine("name of station: " + row["Name"].ToString());

      }

}

catch(bobjFlowNetworkListStations.Model.FlowNetworkListStationsException ex)

{

      Console.WriteLine("Error code " + ex.Result + " " + ex.Message);

}
