iv gotten prity far on my client. last bit to do is to change the parameter of a users location through an argument. but im stumped.

look at my code and see if you can help...

[delphi]
using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using System.Net;
using System.Net.Sockets;

namespace ConsoleApplication1
{

public class Whois
{
static void Main(String[] args)
{
string strHost;

FileStream aFile = new FileStream("config.ini", FileMode.Open);
StreamReader sa = new StreamReader(aFile);
strHost = sa.ReadLine();

TcpClient client = new TcpClient();
//client = new N.Sockets.TcpClient();
client.Connect("whois.net.dcs.hull.ac.uk", 43);
StreamWriter sw = new StreamWriter(client.GetStream());
StreamReader sr = new StreamReader(client.GetStream());

try
{
sw.WriteLine(args[0]);
sw.Flush();
}
catch
{
Console.WriteLine("ERROR: No User Specified");
}
if (args.Length == 2)
{
try
{
sw.WriteLine(args[1]);
sw.Flush();
}
catch
{
Console.WriteLine("ERROR: No Location or user Specified");
}
//CHANGE LOCATION HERE

Console.WriteLine("Number of command line parameters = {0}", args.Length);
Console.Read();
}
else
{
//VIEW LOCATION HERE

// sw.Write(args[0] + args[1]);
// Console.WriteLine(sr.ReadToEnd());
Console.WriteLine(args[0] + " is in " + sr.ReadLine());
Console.WriteLine("Number of command line parameters = {0}", args.Length);
sw.WriteLine();
Console.Read();
}
}
}
}
[/delphi]

i think im almost there. its just a few lines in "//CHANGE LOCATION HERE" that i need to add to change it.

basically. in command prompt i type..


client.exe user01

and it returns "user01 is in the toilet"

or i can type

client.exe user01 "is in a shop"

which changes the location, so next time you type "client.exe user01" it returns "user01 is in a shop".

didnt sw.writeline work?

ya cn try closing the stream afta, sw.close

n i dnt actually get it? i tried telneting whois.net.dcs.hull.ac.uk port 43 n cudnt connect

yeah unfortunately that address blocks anything another than the hull uni computers. so testing outside uni is prity impossible.

i tried sw.write(arg[1]) and also sw.write("dfsfdsfd") and neither changed the value, so im not sure what im doing wrong.

i thought it might b to do with closing the stream to save it. but when i put sw.close(); i get crazy errors.

i should b able to get the answer tomorow in my labs, but id rather not ask them so i look smarter :P

 

[DeathWish]

oh right thts gay thn lol erm... ya r trying to write thing while ur at uni ent ya?

wht crazy errors was ya gettin? lol

}
}

you were right df, was just sw.write, my problem was the first 'try', putting that in made it skip the rest of the program.

now to do the server.
