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 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.

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 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 am the CEO of Virtual American Eagle airlines. I am looking for some help on how to make an automated PIREP system. PIREP stands for PIlot REPort. What I need it to do is connect to my site, make the pilot login, connect to FSX (Microsoft Flight Simulator X) and FS9 (Microsoft Flight Simulator 2009). It needs to track: that the engines are off, the speeds or takeoff, climb, cruise, and decent. Then I want it to track the time that the wheels hit the runway, the time that the engiines go off, then automatically put it into a list and with the push of a button, send it to our site.
View 10 RepliesI 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

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 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?

This is sometimes hard to administrate. So I would like to use a more efficent way. May thought was to Query a DataTable, make changes to it and then call .AcceptChanges and all changes where wrote back to the Database. But this seems not to be the way it works?The method .Update requires that i bring with my own update command, if i have to do that myself, why using the datatable, dataset... anyway?How do you write your DB Backend?
With SQLCommands arrays and variables?
With DataSet, DataTable?
With a VisualStudio genereated template?
With Linq?

View 6 RepliesI made a little VB app to shutdown a laptop after it has been powered on for 2 1/2 hours, and giving the user a little over 8min warning that it is about to be shutdown. However I have nothing in place to stop the user from restarting the device once it is shutdown. What I would like to integrate in this, is a sort of memory where if the user doesn't wait at least 30 minutes, the shutdwon will re-iniate immediatly.
I included the code I did so far.

Like other posters, my problem started out with Excel.exe hanging up in the task manager, even after calling the Quit method. I have tried to recreate the suggestions of using the Garbage Collector and Marshal.FinalReleaseCOMObject methods. The problem that I get now is that after about 20 seconds during which I can still see EXCEL.EXE in the task manager, I always get the Microsoft message box stating: "Microsoft Office Excel has encountered a problem and needs to close." asking me if I want to send or not send a report.[code]...
I receive info requests through email, generated from a web form, which I cant touch, I would, but I can't cos it's an external service. These emails have assigned differents template replies, which I, manually, use to answer them. For this company, this is obvious. For me is a machine work, it¡s totally automatic. So, why don't I set up a rule in Outlook? Because the reply-to address doesn't match with the real one. As it comes from our own server, the reply-to address is our own address.
i just have to answer with different specific templates I already have depending on different fields in the message and send this to an address that is also in one of these message fields. For more data, here is one of the messages I could receive:
