View 1 RepliesReading What Ports Are Sending And Receiving?
Oct 19, 2011I would like to know if there is a way that I can read what a program sends to a device when connected to a comport.
I work with cell phones. I use a few programs like CDMA Workshop, QPST, QXDM, and Many more to communicate with these devices and program them as I need for each cellular carrier. We call this flashing or provisioning.
I would like to create my own program that I can have it send the commands and write to the device what I need to write.
Obviously I know exactly what I need to write to it but I have no idea what commands to use other than using the programs that already have those commands for me.
So for example when I click READ for the NAM on the program, the program automatically reads the name for me. I just want to know how do I read what commands are being sent. Is there a way to listen to the ports?
Sending Multiple Commands To A Serial Ports?
Aug 24, 2010I am creating an application to configure some modems through the serial port. I have no problem sending a single string of data to the serial port and displaying the immediate response to a rich text box. I have 2 problems
1st: how to update the rich text box for any delayed response from the modem
2nd: how to react to the response from the modem, in other words I want to send the next command based on the response from the modem witch is usually "OK"
This is what my code looks like currently to send ans receive data from the serial port. (sport1 is my serial port and display is my rich text box)
sPort1.Write("AT+WOPEN=1" + Environment.NewLine)
With Display
.AppendText(sPort1.ReadExisting())

C# - Sending A String With Sockets?
Aug 20, 2009I am using Nektra's Deviare to hook winsock's send method calls. My ideia is to learn to also send messages through the same socket than the original application. So what I'm doing is when i detect the first call to send message, I save the socket id(the first argument of the send function), so I can use it later.
So here is my code:
uint socket = 0;
[DllImport("Ws2_32.dll")]
private static extern int send(uint socket, string buf, int len, int flags);
[Code].....
This last messagebox is poping up always -1. Why should be it?
edit: calling WSAGetLastError() returns 2. Which I do not know what it means, as it doesn't seem to appear on msdn.

View 3 Replies[2008] Make Web Service Ports?
Feb 2, 2009I'm making an application that tracks jobs we log in our IT department and as I'm often out and about it would be handy to be able to use this app from my laptop and connect in to our server at our office. The problem is that a lot of the places I go block all outboundtraffic apart from port 80 and 443 (for HTTP and HTTPS). Now I know I could write an ASP.NET front end that I could just access over the internet but to be honest I just plain dont like making ASP.NET web pages and so if there is any way I could do this just through my standard desktop app that would be good.
I've heard a bit about "web services" and to me this sounds like a solution but I dont know enough about them to decide if I should use one or not.The main thing that will decide this is whether or not I can make this web service listen on port 80, is that possible?Also, is it hard work making something use HTTPS instead of HTTP so that the data is encrypted? I mean, do you have to do all of the encrypting yourself or is there some sort of automatic function you can use to handle this?

Mar 27, 2009I have been stumped on this for about 3 weeks now.

We are needing to extract from multiple pages and sites so we know that Regex will be the best solution. We can use the same script for everything. This is my first time working with Regex, I got it actually extracting the very first ip[proxy]. I have no idea why it isn't extracting every one on the page. I also have to add the . in between each each octave of the ip. That is weird because I have it in the Regexpession to find the .'s.What I'm Needing is for this to basically scan the whole page and grab all the ipsorts and add them to a listbox.Here is my

View 1 RepliesVS 2008 Client Server - Communicating Over Sockets
Aug 10, 2011I am building a client-server type applications and they are communicating over sockets. This is the first time I am doing such a program and I have been learning off a web example and thought I understood it all but it would appear I am missing something as it starts to work then errors. Here is what I have:
VB
Dim serverSocket As New TcpListener(ListeningPort)
Dim clientSocket As TcpClient
Dim netStream As NetworkStream
Dim BytesFrom(1024) As Byte
Dim DataFromClient As String
[Code] .....
All of the above works and if I open up a telnet command window I can connect to my machine running this code on my specified port and in the command prompt window 'IDENTIFY' appears as it should from the above code. But it then gets to this block an errors on the second line:
VB
'RECEIVE FROM CLIENT
netStream = clientSocket.GetStream()
netStream.Read(BytesFrom, 0, CInt(clientSocket.ReceiveBufferSize))
DataFromClient = System.Text.Encoding.ASCII.GetString(BytesFrom)
Now as far as I can tell it shouldn't be processing the first line
[ netStream = clientSocket.GetStream() ]
Until I send something back from the client because then going on to the second line its trying to process something that isn't there yet.
The actual error I get is:
Specified argument was out of the range of valid values. Parameter name: size
On the line:
netStream.Read(BytesFrom, 0, CInt(clientSocket.ReceiveBufferSize))

VS 2008 Async Socket Connections - Clear Out No Longer Useful Sockets From The Server?
Dec 18, 2009I have been developing an async socket connection server and client program. I have been testing it, and noticed that if I connect to the server from my client and then disconnect. Upon reconnecting I am on a different port(local IP still). This is fine, however when I go to send a message, and the server trys to update all the clients, it eventually hits clients that do not exist anymore. I get the SocketException 10054, and upon connecting/disconnecting enough, it no longer works at all. My question is how do I clear out these no longer useful sockets from the server? I am doing currentsocket.Shutdown(SocketShutDown.Both); and then a currentsocket.Close(); after that. When a user disconnects.
