I tried to create a simple twitchBot using Visual Studio C#, but it won't show up in chat. I could connect with mIRC manually without problems.
I don't recieve any error messages, so it's hard for me to pinpoint the problem.
Any ideas are appreciated.
class Program
{
static void Main(string[] args)
{
IrcClient irc = new IrcClient("irc.chat.twitch.tv", 6667, "gruhlumbot", "oauth:g49tpwj1czs200RETAINED");
irc.joinRoom("gruhlumbot");
while(true)
{
string message = irc.readMessage();
if (message.Contains("!test"))
{
irc.sentChatMessage("response");
}
}
}
}
class IrcClient
{
private string userName;
private string channel;
private TcpClient tcpClient;
private StreamReader inputStream;
private StreamWriter outputStream;
public IrcClient(string ip, int port, string userName, string password)
{
this.userName = userName;
tcpClient = new TcpClient(ip, port);
inputStream = new StreamReader(tcpClient.GetStream());
outputStream = new StreamWriter(tcpClient.GetStream());
outputStream.WriteLine("PASS " + password);
outputStream.WriteLine("NICK " + userName);
outputStream.WriteLine("USER " + userName + " 8 * :" + userName);
outputStream.Flush();
}
public void joinRoom(string channel)
{
this.channel = channel;
outputStream.WriteLine("JOIN #" + channel);
outputStream.Flush();
}
public void sentChatMessage(string message)
{
sendIrcMessage(":" + userName + "!" + userName + "#" + userName + ".tmi.twitch.tv PRIVMSG #" + channel + " :" + message);
}
public string readMessage()
{
string message = inputStream.ReadLine();
return message;
}
}
Can you try adding the character "/" before the command join?
As I remember when I was using Irc all commands where using the "/" character before the command.
Something like this.
outputStream.WriteLine("/JOIN #" + channel);
Share with us the results. Thanks.

everything seems OK and It's worked in as Server.
I run this code in my Windows 10 mobile (as client) and I can received and send messages between my raspberry pi and windows mobile.
Now I want to send and receive message from my android phone.
I tested a-lot of codes but none of them worked to connect android to raspberry pi.
for android I used this nuget package >
https://github.com/rdavisau/sockets-for-pcl
here is my code:
void Send()
{
var client = new TcpClient();
IPEndPoint ipEndPoint = new IPEndPoint(IPAddress.Parse("Ramtin"), 8590);
try
{
client.Connect(ipEndPoint);
if (client.Connected)
{
Debug.WriteLine("Connected to server" + "\n");
var reader = new StreamReader(client.GetStream());
var writer = new StreamWriter(client.GetStream());
writer.AutoFlush = true;
WriteLine("Connected: " + client.Connected);
if (client.Connected)
{
writer.WriteLine("HEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEy");
}
else
{
Debug.WriteLine("send failed !");
}
}
}
catch (Exception ex)
{
ex.Exception("Send");
}
}
"Ramtin" is my raspberry pi host name.
How can I solve this?
Thanks.
Note: I tried to create android as Server and other phones as clients and it's works fine(sending/receiving message). but I don't want android as a server!
So i am making an application which can open connections to remote devices and execute different commands. So yesterday before i left work i was debugging when i got an error. But as my application ignored it and proceeded and having not enough time to fix it immedietly i decided to do it today. When i wanted to make connection with my program again it said it couldn't authenticate (note* the parameters did not change).
So i did some checks to determine the problem, after logging in on the server and running netstat i found out that there was an active connection to port 22, which originated from my application.
Somehow the connection did not show up in my SSH manager until i rebooted it TWICE.
So to prevent things like this in a production environment, how do i prevent things like this.
my Program.cs
class Program
{
static void Main(string[] args)
{
var ip="";
var port=0;
var user="";
var pwd="";
var cmdCommand="";
ConnectionInfo ConnNfo;
ExecuteCommand exec = new ExecuteCommand();
SSHConnection sshConn = new SSHConnection();
if (args.Length > 0)
{
ip = args[0];
port = Convert.ToInt32(args[1]);
user = args[2];
pwd = args[3];
cmdCommand = args[4];
ConnNfo = sshConn.makeSSHConnection(ip, port, user, pwd);
exec.executeCMDbySSH(ConnNfo, cmdCommand);
}
else {
try
{
XMLParser parser = new XMLParser();
List<List<string>> configVars = parser.createReader("C:\\Users\\myusername\\Desktop\\config.xml");
Console.WriteLine("this is from program.cs");
//iterate through array
for (int i = 0; i < configVars[0].Count; i++)
{
if ((configVars[0][i].ToString() == "device" && configVars[1][i].ToString() == "device") && (configVars[0][i + 6].ToString() == "device" && configVars[1][i + 6].ToString() == "no value"))
{
string ipAdress = configVars[1][i + 1].ToString();
int portNum = Convert.ToInt32(configVars[1][i + 2]);
string username = configVars[1][i + 3].ToString();
string passwd = configVars[1][i + 4].ToString();
string command = configVars[1][i + 5].ToString();
Console.WriteLine("making connection with:");
Console.WriteLine(ipAdress + " " + portNum + " " + username + " " + passwd + " " + command);
ConnNfo = sshConn.makeSSHConnection(ipAdress, portNum, username, passwd);
Console.WriteLine("executing command: ");
exec.executeCMDbySSH(ConnNfo, command);
}
}
}
catch (Exception e) { Console.WriteLine("Error occurred: " + e); }
}
Console.WriteLine("press a key to exit");
Console.ReadKey();
}
}
my executeCommand class:
public class ExecuteCommand
{
public ExecuteCommand()
{
}
public void executeCMDbySSH(ConnectionInfo ConnNfo, string cmdCommand )
{
try
{
using (var sshclient = new SshClient(ConnNfo))
{
//the error appeared here at sshclient.Connect();
sshclient.Connect();
using (var cmd = sshclient.CreateCommand(cmdCommand))
{
cmd.Execute();
Console.WriteLine("Command>" + cmd.CommandText);
Console.WriteLine(cmd.Result);
Console.WriteLine("Return Value = {0}", cmd.ExitStatus);
}
sshclient.Disconnect();
}
}
catch (Exception e) { Console.WriteLine("Error occurred: " + e); }
}
}
and my class where i make conenction:
public class SSHConnection
{
public SSHConnection() { }
public ConnectionInfo makeSSHConnection(string ipAdress, int port, string user, string pwd)
{
ConnectionInfo ConnNfo = new ConnectionInfo(ipAdress, port, user,
new AuthenticationMethod[]{
// Pasword based Authentication
new PasswordAuthenticationMethod(user,pwd),
}
);
return ConnNfo;
}
}
Note* i have not included my XMLParser class because it is not relevant to the question, nor does it have any connections regarding SSH in general.
EDIT
i found out i had compiled the application and it was running in the commandline. Turns out there is no error with the code
can someone please help me with this?
i need to check through the System DSN for my ODBC connection to the AS400 servier and create a System DSN if a particular one does not exist.
i've tried googling and have not been able to find anything good for me.

I'm trying to check if computer on the net is online by using code which supposedly to check it by using ARP packets.
I am always getting message that host is offline even when I'm sure that it's online. I have checked on my localhost IP and on some always working IPs such as google.
That could be wrong with this code?
[DllImport("iphlpapi.dll", ExactSpelling = true)]
public static extern int SendARP(IPAddress DestIP, int SrcIP, byte[] pMacAddr, ref uint PhyAddrLen);
private byte[] macAddr = new byte[6];
private uint macAddrLen;
private void Ping(IPAddress address)
{
if (SendARP(address, 0, new byte[6], ref macAddrLen) == 0)
{
open++;
txtDisplay.AppendText("Host " + address + " is open." + Environment.NewLine);
}
else
{
closed++;
txtDisplay.AppendText("Host " + address + " is closed." + Environment.NewLine);
}
}
By using previous code I'm basically trying to do something like following code. But the problem with this code is that when host is closed that it takes like 2 seconds to get the respond which I want to eliminate. Someone suggested to use ARP ping:
private void Ping(IPAddress address)
{
Ping pingSender = new Ping();
PingOptions options = new PingOptions();
if (cbDontFragment.Checked) options.DontFragment = true;
else options.DontFragment = false;
string dataa = string.Empty;
int dataCounter = 0;
options.Ttl = (int)nudTTL.Value;
for (int i = 0; i < nudData.Value; i++)
{
dataCounter++;
if (dataCounter == 10) dataCounter = 0;
dataa += dataCounter.ToString();
}
byte[] buffer = Encoding.ASCII.GetBytes(dataa);
int timeout = 120;
try
{
PingReply reply = pingSender.Send(address, timeout, buffer, options);
if (reply.Status == IPStatus.Success)
{
open++;
txtDisplay.AppendText("Host " + address + " is open. ");
if (cbDontFragment.Checked) txtDisplay.AppendText(" Don't fragment. ");
txtDisplay.AppendText(" TTL: " + options.Ttl.ToString() + " ");
txtDisplay.AppendText(" Bytes: " + nudData.Value + " ");
txtDisplay.AppendText(Environment.NewLine);
}
else
{
closed++;
txtDisplay.AppendText("Host " + address + " is closed. ");
if (cbDontFragment.Checked) txtDisplay.AppendText(" Don't fragment. ");
txtDisplay.AppendText(" TTL: " + options.Ttl.ToString() + " ");
txtDisplay.AppendText(" Bytes: " + nudData.Value + " ");
txtDisplay.AppendText(Environment.NewLine);
}
}
catch (Exception ex)
{
txtDisplay.SelectedText += Environment.NewLine + ex.Message;
}
}
ARP cannot be used for what you are trying to do. It only works over a local network.
It's purpose is to resolve an IP address (which is routed) to a MAC address (which is not). It is never sent beyond a network segment (a lan)
I have some code that uses the WEBDAV 'SEARCH' method to retrieve emails from an an Exchange Mailboxs 'Inbox' folder - my code takes the the innerXML of the HTTPWebRquests WEBresponse.
Using 'selectingSingleNode' on these namsspaces:
'urn:schemas:httpmail' & urn:schemas:mailheader
Alows me to extract the elements:
f:textdescription
d:fromd:subject
f:datareceived...and so on
I then create a collection of these details in a list and using the 'Subject' along with the URI use the 'PUT' method to recreate these messages in the 'draft's folder before using the 'MOVE' to send the mails (puts them in the sent items using '/##DavMailSubmissionURI##/"' statement.
The problem i have is the nature of the emails i am dealing with tend to come in with the same subject line so it gets confused with which emails have been sent/or not.
Does anyone know of a way around this, I dont know why the 'PUT' relies on the Subject line for the URI to the mail resource rather than say the HREF tag which is unique. Any ideas:

Using just the subject to identify email is, indeed, not a good way. If I remember it's correct, there are no automatic / obvious email id for exchange / webdav?
If you parse the subject to pick message, I would also pick more information of the email envelope - Like it size, length to create my own id. The best step should be that you create some sort of hash (check Cryptography) out of the whole message body OR i.e. first character of first xx word in the email body (heavier processing though). That will end up in same hash value everytime you call it on same email envelope. Of until the email content is leaved unchanged.
Looks like you're working with Exchange 2003. Be aware that WebDAV is no longer supported in Exchange Version 2010... and with 2007 and newer you can use a WSDL to do everything you need. All you need is an Exchange 2007 CAS to do this.
What I mentioned is a better longer term approach and has less headaches than parsing unsupported WEBDAV XML
To answer your question, there is a property that is unique per message. Use MFCMapi (on codeplex) to look for it. The property will be named "MessageURL" or something like that. Use that property in the URL for your webdav calls.
