The project so for has been developed purely in visual basic as that is what I know, however a new requirement is that I need to present this also with a web based element, whilst the existing Visual Basic form still runs.

That may sound a bit confusing but basically I want a system that can be fully controlled locally (ie on the PC the usb device is attached to) using a visual basic form. But want some limited features also available through a web browser (such as just switching light on or off) so control of the home can be done on the move.

Thanks in advance for any advice people have to offer as I have done a fair bit of searching around but am still at a loss.

i need a solution where the vb app and asp web page can interact together controlling the board; so if a change is made on the web, it is also reflected on the vb app
