I already worked with the dlls which were built with .Net framework 4.5.1. So this wasn't the problem. But because of your recommendation I changed my App Net version to 3.5 (which was possible without much work) and used the 'normal' dlls. And this works perfect!
Thanks a lot for your help! No I can continue =)

Do You have any ideas where my I mistake is located?

Based on your output, the TETCSharpClient.dll does not seem to load. This may be related to the .Net version of the C# SDK. The SDK is build for .net 3.5 to ensure support for Unity.

I would suggest that you clone the C# repo from github, change the target framework to 4.5.1, rebuild and use the resulting DLL.

Please try this and let me know how it works out.

Thanks for your fast replay!

I know about the sample but I wanted to use the simple example in the c# tutorial. I think perhaps I missed some code or placed it wrong?

I think I used the wrong word. It is not an error where the complete application stops. It is just an output.
So this is what I get as output when I start the app and start the calibration in the app (the calibration stops after the point moved once, like I described above, but the app is still running).

It's a bit hard to see exactly why it fails to connect with the server. I would need the full exception message and/or stacktrace to diagnose.

It's often helpful to enable automatic breaking on error. In Visual Studio this is done under "Debug", "Exceptions..", check thrown on "Common Language Runtime Exceptions".

We have a minimal calibration sample available.

Also, note that you will have to add listeners for the interfaces (see sample).

Integration of Calibration in WPF Desktop App doesn't work

2015-08-10T12:04:21+02:00

Hey,

i'm trying to implement a Calibration at the beginning of my WPF App.
The App has a Main Window (MyApp.xaml) and this window contains a frame which leads to a page (Calibration.xaml). I started the server before i started the App.
I also referenced TETControls.dll, TETCSharpClient.dll and Newtonsoft.Json
My project works with the .NET Framework 4.5.1

MyApp.xaml.cs looks like this:

Code:: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading; using System.Threading.Tasks; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Shapes; using TETControls.Calibration; using TETControls.Cursor; using TETControls.TrackBox; using TETCSharpClient; using TETCSharpClient.Data; namespace EyeTribe { public partial class MyApp : Window, IGazeListener { public MyApp() { InitializeComponent(); // Connect client GazeManager.Instance.Activate(GazeManager.ApiVersion.VERSION_1_0, GazeManager.ClientMode.Push); frmMainContent.Source = new Uri("Calibration.xaml", UriKind.Relative); } public void OnGazeUpdate(GazeData gazeData) { throw new NotImplementedException(); } } }

And my Calibration.xaml.cs (which should contain the Calibration) looks like this:

Code:: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Navigation; using System.Windows.Shapes; using TETControls; using TETControls.Calibration; using TETControls.Cursor; using TETControls.TrackBox; using TETCSharpClient.Data; using TETCSharpClient; using MessageBox = System.Windows.MessageBox; namespace EyeTribe { public partial class Calibration : Page { public Calibration() { InitializeComponent(); } private void btnCalibrate_Click(object sender, RoutedEventArgs e) { CalibrationRunner calRunner = new CalibrationRunner(); calRunner.OnResult += calRunner_OnResult; calRunner.Start(); } private void calRunner_OnResult(object sender, CalibrationRunnerEventArgs e) { switch (e.Result) { case CalibrationRunnerResult.Success: //MessageBox.Show(this, "Calibration success " + e.CalibrationResult.AverageErrorDegree); break; case CalibrationRunnerResult.Abort: //MessageBox.Show(this, "The calibration was aborted. Reason: " + e.Message); break; case CalibrationRunnerResult.Error: //MessageBox.Show(this, "An error occured during calibration. Reason: " + e.Message); break; case CalibrationRunnerResult.Failure: //MessageBox.Show(this, "Calibration failed. Reason: " + e.Message); break; case CalibrationRunnerResult.Unknown: //MessageBox.Show(this, "Calibration exited with unknown state. Reason: " + e.Message); break; } } } }

So I get errors while the app starts:

Exception while connecting to EyeTribe Server: TETCSharpClient.GazeApiManager.RequestTracker(ClientMode mode, ApiVersion version)
TETCSharpClient.GazeManager.HandleServerConnect(Object stateInfo)

and

Error initializing GazeManager, is EyeTribe Server running?

But I did start the server!

And as soon as I click on the Calibrate Button the Calibration starts, but the dot only moves once. It simply stops there and nothing happens (the dot remains at this point).

I get these errors:

Calling CalibrationStart(), but TET C# Client not activated!Calling CalibrationPointStart(), but TET C# Client not activated!"

Calling CalibrationPointEnd(), but TET C# Client not activated!Calling CalibrationAbort(), but TET C# Client not activated!

So what did I miss? I tried to follow the c# tutorial and looked at the samples, but I can't figure out a solution.
