Is It Possible To Use A Serial Port Like Session In C#
Jun 17, 2010
I am using serial port communication in my asp.net webform application...
[code]....
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...
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 am making application with portable data terminal which connected to serial port. User will go with portable data terminal and scan data with it than we will connect it to PC and read all the data from it.
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)
Can I change algorithm of serial key template of web set up project ? If I am not able to change algorithm, what could be the best method to implement product key(serial number) concept in web setup project.
I want to generate serial number in gridview but the serial number should be equal to the count of records for a particular column(in my case No. of Villages).
I know how to generate serial number but i am unable to generate number of rows equal to the number of records of my datatable column(Village_Name---say for example 45 rows--- any no. of rows)
I need to display a table with various info (names, dates, serial numbers, notes). In addition, there is one field I need to be one of three specified values (Raise, Lower, Release). What view would be the best/easiest to implement which would let me add/edit/delete entries as well as provide a drop down option for the Raise, Lower, Release options?
I can specify a port number with SmtpClient object in ASP.NET, what I am wondering is, is that just the port .NET uses to send mail to the SMTP server? Or will that dictate what port for the SMTP server to use? Or is it that it MUST match the port configured for the SMTP server?
I have a managed DLL which communicates with the devices attached on COM/Serial ports. The desktop Winforms application sends requests on ports and receives/stores data in memory. In Winforms app I have added a reference to DLL and I am using the methods. This works well. Now, there is a situation where I need to show this data from serial/com port on a web-page. And also users should be able to send requests to the ports using this DLL. I have made a web app in ASP.NET (2.0). Added a reference to the DLL. I am able to use this DLL, the DLL communicates on the COM upon button click on web-page and also the response is shown on web page. However I am not happy with the approach and strongly feel that this is a bad approach. Also the development server crashes after 3 -4 requests. What is the best approach in this scenario. If I use a windows service then how would my ASP.net app will communicate with the Weindows service.Or can this be easily done using WCF. I have not used WCF any time nor any of .net remoting technique.
I following this article for sending SMS it is a winform application.. I have referenced all the Dll's to my asp.net application. I use an aspx page to detect a mobile device connected to a PC..... But it alwys shows COM 'n' Port could not be opened.
using SMS; using GsmComm.GsmCommunication; using GsmComm.PduConverter; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { GsmCommMain comm = new GsmCommMain(6, 9600, 300); comm.Open(); if (!comm.IsConnected()) { Response.Write("No Phone Connected"); } else { SmsSubmitPdu pdu = new SmsSubmitPdu("test", "+919999999999", ""); CommSetting.comm.SendMessage(pdu); } } }
EDIT:
I use the web development server that ships with Visual Studio... If go to Control Panel -> Phones & Modems -> Modems i could see my mobile connected in com6.. i have tested the winform application it works fine.Is this the answer? ASP.NET pages are supposed to work.What is happening over here is that when you click on open_com button, the ASP.NET page posts back to itself, executes the event handler i.e., opensthe port. Then when the page finishesprocessing the post back, it is unloaded. At this point the COM1 objects is also destroyed.
