Reading Data From Client Computer Serial Port Using Web Application?
Jan 2, 2010
Is it possible to read data from serial port of client system using asp.net web site. Here is my scenario
I will be having computers connected in LAN and a web application which resides on server. Each client computer will be connected to a external machine using serial port and is ready for reading data, external machine measures equipment details and sends through serial port.Now I need to read the same data using my web page, is it possible?
Like when we do video chatting our web page reads data from web cam and sends the stream to web page. this way how can I read data from client machine to web page.

I'm new here and I've run into a problem with my first asp project. I've taken over this webpage and am currently trying to add functionality to take in data from a serial port and then put the parsed info into a series of textboxes. Right now I can get the data from the serial ports but the text boxes refuse to show the data.
[Code]....
NOTE: These are System.Web.UI textboxes, so I can't use text delgate and Invokes (which is the usual solution I have seen)

This method works when i send i single message... But when want to send sms in bulk opening and closing port everytime is not a good idea... So my question is it possible to use a serial port like session in c#?... When i open a port i want it to be open for 1 hour and then if my time expires i want to close the port and open it the next time...

I have an asp.net (FW 3.5) web app that runs on an internal network. One specific page needs to "report" in to the web server that it is active and not locked up. I need to be able to run a script (or something) at the client to report the pc's computer name in that report. I cannot find a method that does this. I found several things that would report the WAN IP or host name, but this appears to all be for external facing sites.

What is the best way to check if client has an open port, and if it's forwarded properly?The app works like this currently:Client creates a socket for incoming connections and wants to notify everyone about his open port. Client also tries to setup port forwarding using UPnP (but it's not always present and enabled).Client then sends his port to the "central" known server.Server should check if the port is open (forwarded properly) and return its status.If there is a forwarding problem, client will notify user.The goal is to have an the IP + port info saved on the server to be able to give it to other clients. I could try to open a Socket from server to client and see if it fails, but is there an easier (faster) way to do it?For example, this site does something like that: http://www.canyouseeme.org/

Is there a way to read and write files on a client's computer using a web based application? Basically I need to create a internal app that will take two input CSV files and convert it into an output CSV file that is written to the same location as the input files on the client's computers.
Since this is an internal app, I don't have to worry about security. I can easily write a C# app for this but I want to create a ASP.NET app (or any other format). I even looked into creating a HTA application.

Given a file path on client machine, is it possible for me to get the content of the file from that
location and show that content in browser using any client scripting language.when i explored on this , i got following information.1.Client scripting languuages are not allowed to have access to client system as it is a hugesecurity threat.2. We can use ActiveXObject (FileSystemObject) to have access to client system, but it haslimitations like it only works in IE & client also need to change IE settings to make sure that thisactive x componet runs in his browser.Does any one have any alternative solutions with Jquery/Ajax or any client scripting language(that is cross browser compatible and works for all file types.)
