K8090 from asp.net page

So, I have a K8090 and it works,

I have made a small test application in visual basic with visual studio express 2010 and results are very good.

Now i want to move from a Vb application to a website because I want to give commands to that single K8090 (connected to the home web server) from several web clients.

This does not work and I get a " not declared. it may be due to its protection level" warning in web developer express. However, the card is visible as toolbox item in the web developer express toolbox items.

what is going wrong here?
