Dear Dario,

Here my ReadBinaryFile() method and GetCurrentValues :

--- "ExternalFeed.cs", ExternalFeedSimulator class---

public class ExternalFeedSimulator
{
private double [] m_refprices = null;
private double [] m_openprices = null;

private double [] m_minprices;
private double [] m_maxprices;
...


public ExternalFeedSimulator()
{

_stockGenerators= new Hashtable();
...
}

//Get data stock from outside, read "security.dat" file
public void ReadBinaryFile()
{
ISecurityStructReader reader;
reader = new ReadSecurityStruct("C:\\TEMP\\BACKUP14\\SECURITY.D AT");

nStock = 0;

if (reader.Open())
{
arr = reader.Read();

nStock = arr.Count;
m_stockSymbol = new string[nStock];
m_openprices = new double[nStock];

for (int i=0; i< nStock ;i++)
{
Struct_Security item = (Struct_Security)arr[i];

m_openprices[i]= item.OpenPrice;
m_stockSymbol[i]= item.StockSymbol;
...
}
}
reader.Close();
}

---- "ExternalFeed.cs" file, ExternalFeedProducer class ---

public void Start() {
lock (this) {
if (_thread != null) return;

_thread = new Thread(new ThreadStart(Run));
_thread.Start();
}
}

private void Run() {
do {
int waitMillis= ComputeNextWaitTime();
Thread.Sleep(waitMillis);

if (_listener != null)
{
_listener.OnEvent(_itemName, GetCurrentValues(false), false);
}

} while (true);
}

//How about this method? Is it correct?
public IDictionary GetCurrentValues(bool fullData) {
lock (this) {
IDictionary eventData = new Hashtable();

eventData["ceiling"] = _ceiling.ToString("#,##0.##");
eventData["floor"] = _floor.ToString("#,##0.##");
...
}
}

How about Start(), Run() method in "ExternalFeedProducer" class? i need remove ? Because it has error in StockListAdapter :

---
Unhandled exception : System.IndexOutOfRangeException : index was outside the bounds of the array at Lightstreamer.Adapters.Data.StockList.ExternalFeed Simulator.Run()

----

Quotes :
"Any unwanted behaviour (for instance, the Data Adapter not receiving all read data) should be inspected with a debugger" --> i don't understand this, u mean if i config in "lightstreamer_log_conf.xml" file and set priority value = "DEBUG" :

<category name="LightstreamerLogger.pump" class="org.apache.log4j.Logger">
<priority value="DEBUG" />
</category>

the Data Adapter not receiving all read data after every 5 seconds?

and How to check or to recognize my Remote Adapter would still forward all updates to Lightstreamer Server?

Can u help me?
