Unless you physically connect the weight scale to the Web Server machine, your 'local machine' must upload collected data to the Web Server one (say on a database).

Physically not connected to server.
Is there any way that weigh Scale Machine give response in web page.
(I alrady made a serial port code in my class file(.vb File) under app_code it is working fine if my local machine and server are same)
please guide me if is there any way that machine give response in web page or other way.

As I already wrote, the local machine needs to upload collected data to the Web Server in order to enalbe the latter to show weight scale response on a web page.
That is you have to establish communication between your local machine and the Web Server one.

ok is there any way that I can get data in web page from attached machine in local compute. If its possible than I can go further to upload a data.
(do you got my concern ?? if not than I can explain again.)

Of course there is. I guess accessing a database is a simple way to accomplish that, but you might use, for instance, TCP communication as well.
