Figured it out. I was using the wrong version of the server.

Everything works now.

Thx for the feedback Chris. Would you mind posting this as an issue on the GitHub repo in question? Maybe with a link to this thread? Then I'll see to it that someone looks at this asap.

I also tried to run the sample code downloaded straight from github.

The calibration program can run the calibration steps (the moving dot) like the eyetribe UI, but once it's done calibrating it doesn't exit the calibration overlay and if I press esc to exit then a message pops up saying calibration failed. the graphical display which is supposed to show whether the eye tracker always displays the red slash even though the eyetribe UI can detect my eyes. and The mouse control button doesn't do anything even though it works through eyetribe UI. The only thing that seems to work is the "Calibration Quality" displays the same as what eyetribe UI reports.

Scroll pulls up the image which I can navigate with my mouse. But again if it's supposed to respond to my eyes I'm not seeing it.

I've uploaded the complied program here. Does it run on your side?

The only thing I did was download the code from the site and compile it.

As far as I can tell, the OnGazeUpdate function never runs.

I suggest taking a look at the C# samples to learn what you are doing wrong.

Hi, I'm trying out the code samples provided on the Dev page and can't seem to get it working.

As far as I can tell, the OnGazeUpdate function never runs. I assumed there was something in IGazeListener that called OnGazeUpdate whenever the tracker had an update available. Should I add it to a delegate manually?

Hi everyone, could you please assist me on this. When i run the code below it says "the "protocol" is inaccessible due to protection level". does anyone know how to make is accessible? Thanks so much.

We are unable to help you without more knowledge of you project and setup. Please ZIP your entire project and make it available in this thread or point me to a GitHub branch holding you project.

I am using visual studio 2015. I have tried to rebuild the solution several times but it actually gives the same error.

The error you are getting is related to some of the NuGet packages used by the SDK. Seems they are not being properly downloaded (which is an automated process that requires internet connection).

As stated in the documentation on GitHub (under 'Building') the C# SDK project uses Visual Studio 2013, not 2015. It should support VS2015 though. My best guess is, that the differences between VS2013 and VS2015 is causing the issue you are facing.

I suggest trying the following:
1. Clean checkout of the C# SDK repo and import to VS2015. Build->Clean. Build->Rebuild.
2. Install VS2013, clean checkout of the C# SDK repo and import to VS2015. Build->Clean. Build->Rebuild.

I have double-checked that solution 2 works with my VS2013 installation.

What version of visual studio are you using?

Have you tried to clean your solution and rebuild? That will redeploy the needed NuGet packages

Dear everyone,
I have tried to access the C# SAMPLE program from Github, but once i try to run the code in Visual studio it gives out several error msgs. Is there anyone who has experienced the same problem? How to tackle it?
Below is one of error messages.

Have a look at our GitHub repositories. The C# samples contains an open source calibration example.

C# • Custom C# Calibration

2016-06-09T15:59:56+02:00

Dear all,
does enyone have already succeeded in customizing the calibration procedure to have different (bigger or bitmap-based) targets?
We are dealing with young children with impairments (also cognitive), and it is rather difficult to have them fixate long enough small circular targets like the ones used in the standard calibration procedure.

Any hints are more than welcome

Kind regards

Paolo
