Web application under Visual Studio 2013 (or 2008)

Hello sirs,
I’d like to have an example of web application developed in visual basic under Visual Studio 2013 (or 2008) to manage my K8090 usb relay card.
I downloaded and arranged the samples from your site, so the application runs perfectly in Desktop mode, while I cannot fully manage the card in ASP, I only succeeded in toggling relays.
I need to toggle relays and to read their status (I couldn’t make the event K8090.CommandReceived working). I think there’s something wrong in declarations, as Velleman.Kits.K8090Board object doesn’t work properly with its events.
Thank you very much

The K8090Board class uses the native library K8090D.dll. This library uses the Windows message queue to signal events. Only desktop applications have message queues, so it will not work for web applications.

The .NET Framework 4.5 has a SerialPort class that may be suitable to communicate with the K8090 in both directions.
