Interniche / Website Problem

hmm... okay but how can i send this info to the site? have you a example for this?

My first idea was, if i press a button than change a variable x this value from 0 to 1, now came the problem, how can i transmit this to the page? or can the page read this variable from the c-code? i believe, that i must send this information to the Site, as you wrote it. But i have realy no idea how can i make this, have you an example or a snippet code?

thanks for the Help.
