DLL with DataAccess SDK C#
Hi there,
I am able to run the c# DataApiUsageExampleRealtimeData as a console application all right.
Now that I need the Eikon Data API within a DLL.I have referenced the "ThomsonReuters.Desktop.SDK.DataAccess.dll" and the other UDAP dll alright.
I cannot get any events to fire for
DataReceivedCallbackInit
after this code runs without any issues:
subscription =
realtime.SetupDataSubscription()
.WithRics("EUR=")
.WithFields("BID", "ASK", "TIMACT")
.WithDateAndTimeMode(TimeAndDateMode.GMT)
.OnDataUpdated(DataReceivedCallbackInit)
.CreateAndStart();
I believe it has something to do with the threading model:
private static readonly DispatcherFrame Frame = new DispatcherFrame();
Any idea on how I can achieve this kind of threading within the DLL I am trying to code?
Do I need to put the above code into a new thread?
Thanks for support,
Michael

Please make sure that Windows message pump is running on the thread housing Eikon .NET API objects. See this thread for more details.0

I found a way how to do it. If anybody is interested, here you go:
private DispatcherFrame frame;
/// <summary>
///
/// </summary>
public Eikon()
{
new Thread(p => OnConnectInternal())
{
IsBackground = true
}
.Start();
}
private void OnConnectInternal()
{
frame = new DispatcherFrame();
DataServices.Instance.StateChanged += Instance_StateChanged;
DataServices.Instance.Initialize("DataApiUsageExampleRealtimeData2");
var realtime = DataServices.Instance.Realtime;
subscription =
realtime.SetupDataSubscription()
.WithRics("EUR=")
.WithFields("BID", "ASK", "TIMACT")
.WithDateAndTimeMode(TimeAndDateMode.GMT)
.OnDataUpdated(DataReceivedCallbackInit)
.CreateAndStart();
Dispatcher.PushFrame(frame);
}
private void Instance_StateChanged(object sender, DataServicesStateChangedEventArgs e)
{
switch (e.State)
{
case DataServicesState.None:
break;
case DataServicesState.Error:
break;
case DataServicesState.Up:
break;
case DataServicesState.Down:
break;
case DataServicesState.LocalMode:
break;
case DataServicesState.EikonClosing:
break;
case DataServicesState.EikonStarting:
break;
default:
throw new ArgumentOutOfRangeException();
}
}
protected void DataReceivedCallbackInit(IRealtimeUpdateDictionary instruments)
{
try
{
foreach (var ins in instruments)
{
foreach (var kvp in ins.Value)
{
switch (kvp.Key)
{
case "BID":
break;
case "ASK":
break;
default:
break;
}
break;
}
}
}
catch (Exception ex)
{
}
