I have the server and the client in the same machine (idk why is this web-oriented, it wasn't my call). And I have to update the webform label every time the scanner reads something (it's connected through serial port). Any ideas?
BTW: I'm using C# and ASP.NET running on Windows 7.
This is what I use in my local serial port application:
using System.IO.Ports;
SerialPort testPort = new SerialPort();
testPort.DataReceived += testPort_DataReceived;
Every time data is received, the DataReceived function is called. I use it to read input into a buffer.
Tip: To link the DataReceived function you can just hit tab after typing "+=". Visual studio should build the function for you.
I am not sure about webforms, but for capturing serial events this should work.
