VS 2010 Sending A Command To Telnet?
Apr 14, 2010
I have wrote a nice little app in VB.Net to connect to an IP device via telnet and send a command, then write the reply to this command into a text file.I have everything working appart from the command.I need to send "Ctrl+a I2100" so if I was doing it manually in a dos box with telnet I would connect, then hold down Ctrl key and a then release, then type I2100 How do I do the Ctrl+a bit in VB. The line of code I have at the moment, is
client.SendCommand("Ctrl testing")
Now this obviously sends the word Ctrl testing to the telnet device.

I'm writing a GUI-based app in VB.net that talks to a LambdaMOO server via telnet, sends commands to display the object hierarchy, then parses the output and creates a visual representation of the object hierarchy.So my question is: is there some kind of "telnet client" class for .NET to simplify the sending and receiving of data, or do I have to write my own using the socket API?

how to send a procedure call to a Command Button.
What I would like to do is have one button be able to call any number of other sub routines when needed. In other words...the app is running and I need it to stop so the user can either read information presented...or make choices...then click the CONTINUE button to pick up where the app left off. However, I need this to happen many times across several forms and modules.
I know I can use a MessageBox and get the same effect..

I am connecting to a website using a Httpwebrequest command... this is going good as far as I can tell but to test it I want to send a command to the website that presses a button on the website... of course this will not be a physical push as I do not have a browser but I just want to use the "submit" button on the site...So when it sends the request to the website it will also send a command to "press" the submit button and do the same action that the submit button normally would if I had pressed it through a web browser...y code is as follows:
Dim r As New Random
Dim s As New Random
Dim l As New Random

I am having a little trouble with the serialport object in VB2008. I have a program that will send a command to the slave device however the program will not read the data from the slave device. I know my computer is communicating with the slave device because in hypertem it has no problem. For example I send the word "AT" and I should get back a response of "OK",

I am working on writing a program that needs to send a command to a specific port on the same computer, I have that working fine. There is another piece of software running that is listening to that port for some commands (read on).
Dim myTcpClient As New TcpClient
myTcpClient.Connect("127.0.0.1", 61225)
Dim networkStream As NetworkStream = myTcpClient.GetStream()
However when I try to send a command I get no response...
Dim outStream As Byte() = System.Text.Encoding.ASCII.GetBytes("0x33")
networkStream.Write(outStream, 0, outStream.Length)
networkStream.Flush()
I have been given a list of protocols that I need to send to that port. What I have been told is that the size (in byes) is 1 and the value is "0x33" with no parameters. I am completely new to sockets and sending data through tcp.

I'm new to VB and i'm using VS 2008, i just wanted to know if there's a set of instructions you can provide me that can enable me to auto login when you telnet on a node. That is when you telnet an ip address of that particular node it will automatically log on the system with your username and password already inserted in the instruction. So it wont have to prompt a screen saying insert username or password

I am using Telnet in VB to read a temperature and RH sensor. I don't know that the data is the exact same length every time. I have pasted the code below. This code does get the data back. I have also pasted the unparsed and parsed data as well.... Sometimes I get more or less data than the time before and I think this is because I am not reading the entire buffer. How can I make this code run a little better so that I can get the proper data every time? Below the code is a sample of several readings. You can see how I get bad data periodically.
Unparsed
" 24.4155 45.2235 11.7921 200.9005 45.2372 45.2235 -42.0242"
Parsed (replaced " " with , and then " " with ,)

I have a central server and I need to write a bit of vb.net which will see if I can telnet to a specified server on a specified port.Is there anyway this can be done in VB.net? I thought about sending command prompts to the remote server to execute telnet, then output the logs of netsh and read those and send the information back to the central server for review.
Its a very messy way of doing it, so I was just wondering if there was an easier way

I have two main troubles. The most important is the telnet one. I have another program which sends data via telnet locally on the PC. It requires a login and optional pass. I can connect and draw data which comes in 77 byte packets.
The problem is, the first packet of data doesn't display until the 2nd one comes in, which for this arrangement could 10s or 24 hours depending on the final user's intended use. This staggered data rx continues until termination of the program. I've used tcpClient.Available() to confirm that my app is seeing the data almost the instant it leaves the other program but for some reason the message isn't passed until the 2nd packet arrives. I'm sure I've probably implemented this in a most cumbersome way so any streamlining.
The second issue (which is contributing in part to the first) is the timer which here uses a freeby snip from a forum somewhere - it screws with the app's menu's controls and program flow. I've tried the VB2008 timer but can't seem to make sense of the best way to use it in this context. I think I've been looking at the screen too long and can't see the obvious.

An currently writing a vb.net application to send and receive information from a client via telnet. Am using System.net.Sockets to do this. I can send data great and get data back is ok. So the Problem is in the command window after I telnet in to the server application, when i press the delete key the cursor moves back a character and doesn't delete the character, just over writes it and when I read the bytes in I get the deleted character and the ascii value for the delete key and then the replacement character. I have seen another telnet application that shows the deletion of characters in the Command window.

I am trying to make an application which logs on to a server using the telnet protocol runs a couple of commands and stores the output of these commands in a text file.The problem is that I cant really seem to figure out how to negotiate the telnet commands. I have done a packet capture of a telnet session todifferent servers using a packet capturing program and I dont seem to find any fixed pattern. Every server negotiates the command in its own different way and in a different sequence, moreover the commands exchanged are not the same.
What I want to do is to exchange the bare minimum commands which will allow me to log on to any server via telnet, run my commands, take the output and logout.I have searched the internet for such a set of 'general' telnet commands but I wasnt able to find any.

I'm using an Asynchronous Method to send data across the TCP Protocol. For the most part it seems to be working, but recently, I've been getting results that have missing bytes to them. How am I actually able to figure out what's missing on the sender's site and make sure all the data gets to the end? For example: my end client receives 1408 bytes of data when I sent 1532 bytes. I sent an array with a length of 1532 and the client only got 1408.

I'm having trouble with passing an array between subroutines
I have an array called "lines" which is loaded from a text file and then edited according to a series of checkboxes within one subroutine. Each line in the array is essentially a line from the text file
I then need this array passed to another routine so that it saves to a new text file once the save button is pressed. (in this case just the top 5 lines)
At the end of the section that creates the array i have placed this
From File Edit
Call Savefile(Lines)
The section of code below is from the section once the button is pressed
Save Code
Sub Save_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Savebutton.Click

I have a problem with one application, the application send emails to notify the users of some events that occur. The application works just fine when the user it's connected by wire, but when it's wireless the emails can't be sent.I did a little research and i found out that the server just allow to send email messages from the users authenticated, the wireless LAN doesn't authenticate the users...So how can i set the credentials/authenticate myself in the server when I'm connected by wireless, to be able to send emails?
