[C#] Access violation random

[huypl]

Hi All !
I use Neurotec SDK to develop an application by C# (window form application)
Function is:
- create subject
- create face and assign to a faceview.
- capture a face and identify via Neuro Server.
When i run, sometime it throw Access violation exception and crash (Cannot try/catch this exception).
This is my code

Code: Select all

//create client
NBiometricClient _biometricClient = new NBiometricClient { BiometricTypes = NBiometricType.Face, UseDeviceManager = true };
NClusterBiometricConnection nClusterBiometricConnection = new NClusterBiometricConnection(ConfigureObject.SERVER_IP, ConfigureObject.CLIENT_PORT, ConfigureObject.ADMIN_PORT);
_biometricClient.RemoteConnections.Add(nClusterBiometricConnection);
_biometricClient.Initialize();
//create subject
NSubject _subject = new NSubject();
NFace _face = new NFace { CaptureOptions = NBiometricCaptureOptions.Stream };
facesView.Face = _face;
_subject.Faces.Add(_face);
var status = _biometricClient.Capture(_subject); //It crash here.
if (status == NBiometricStatus.Ok) {
NBiometricStatus status2 = _biometricClient.Identify(_subject);
}


- The code run under BackgroundWorker.
- I use visual sudio 2017, build under x86, .Net Framework 4.6.1
- Lastest neuro sdk.

Please give to me some suggest.
Thanks

Hello huypl,

Send source code of application, which would reproduce the same issue on our side to support@neurotechnology.com with issue description, also provide following information:
Can you reproduce it using our unmodified samples?
Full crash log.
SDK revision number(can be found in SDK root directory, in Revision.txt file).

P.S. Since .NET version 4 you can't catch Access Violation Exception by default, but with little modification you can catch it, read https://msdn.microsoft.com/en-us/library/system.accessviolationexception(v=vs.110).aspx .
