Hey guys, for some reason this stupid TCP server doesn't loop after a client disconnects from it. How can I have it continue to loop so when people do disconnect from it, it continues to accept connections. Here is the code.
using System;
using System.Text;
using System.Net;
using System.Net.Sockets;
public class serv
{
public static void Main()
{
int c = 1234;
try
{
IPAddress ipAd = IPAddress.Parse("69.10.61.145"); //use local m/c IP address, and use the same in the client
/* Initializes the Listener */
TcpListener myList = new TcpListener(ipAd, 7575);
/* Start Listeneting at the specified port */
myList.Start();
Console.WriteLine("Login Server is running.");
Console.WriteLine("Connection :" + myList.LocalEndpoint);
Console.WriteLine("Waiting for logins...");
Console.WriteLine("================================");
Socket s = myList.AcceptSocket();
Console.WriteLine("Connection accepted from: " + s.RemoteEndPoint);
byte[] b = new byte[100];
int k = s.Receive(b);
Console.WriteLine("Login Attempt Recieved from: " + s.RemoteEndPoint);
for (int i = 0; i < k; i++)
Console.Write(Convert.ToChar(b[i]));
ASCIIEncoding asen = new ASCIIEncoding();
s.Send(asen.GetBytes("Login is invalid." + s.RemoteEndPoint));
Console.WriteLine("\nAccess Denied.");
Console.ReadLine();
return;
/* clean up */
}
catch (Exception e)
{
Console.WriteLine("Error..... " + e.StackTrace);
Console.ReadLine();
}
}
}

Either look up the async methods or wrap a while loop over the hart of the operation.
I personall recommend the async methds and they also nearly force you to do all the work in seperate methods, which actually comes in handy when you get used to it.
For the while loop, consider using a global bool value which you change when stopping to listen.
The while loop should cancel then and your application should continue.
Though, this doesn't really work as you may want to depending on how you build you loop.
In most cases it will still wait for a last connection to be made before it will finally break.
Start the loop before AcceptSocket call and end it when you're done, in this case below the Access Denied output.
I hope this helps a bit, TCP/IP is always confusing at the start...

I just wrapped while(true) around it, will that work? Also can you take a look at my other thread. its very important.

I'd seriously recommend creating a new thread to handle the connection after you've accepted the incoming connection - that's the usual way these bits of code work. One thread just sits there and accepts connections, each time one comes in the socket is passed to a new thread to handle the conversation and the original thread carries on listening for subsequent connections.
What sort of server can only handle a single incoming connection? Also, take a look at TCPClient , it provides nicer access than Socket .

Hi,
Look at the following article[^], I think it might help you alot.
Kind regards,

Is there a way to do it?
IE:
30000
I want it to be 30 000
|
|

You can use the .ToString() method to make it to a string.
There is a regexp function to do such a thing, but I forgot about it.
However, here is snippet that should do the trick aswell.
int number = 3000000;
int lengthPerSplit = 3;
string splitText = " ";
string result = number.ToString();
for (int index = result.Length - lengthPerSplit; index > 0; index -= lengthPerSplit)
result = result.Substring(0, index) + splitText + result.Substring(index, result.Length - index);

try this as a simpler solution, just keep adding sets of 3 #s
string.Format("{0:### ### ###.00}", 30000000);

string.Format is probably the easiest way to get any kind of formatting you want.
There are three kinds of people in the world - those who can count and those who can't...

Hello all, I got a question and I unfortunatelly can't find a solution for it on the web.
I'm fairly sure it's out there, but probably I'm using the wrong criteria...
The main goal of this mini-project is, is to create 1 file with a GUI.
The user selects one of the options and the right executable will be launched.
Now there is no option to leave those executables outside of the entrypoint file and thus HAVE TO be embedded into it.
The embedding is not the problem, but the executing of the file is.
Since I don't want to save the file to the disc upon launching it and only will have a stream for it, it must execute it somehow from here.
I may be doing a comlete wrong approach, I'm open to anything that does what I want it to do:
1. Embed the file(s) to the main entrypoint file (this 1 big happy .exe file)
2. Execute a file without writing it to the HDD first and then execute it (the user may not be able to get the embedded .exe that easy).
I thank you for your time and hopefully you know a solution
Yours sincerely,
OsoreWatashi

You can't. It has to be saved to disk. The Windows Loader will not start a new .EXE from a stream it does not know how to manipulate.

What a shame. They should add that. Windows could really use another attack vector.

Hi,
I´m looking for control like Corel Draw tool text editor or similar.
Do you know something like this ?
I´m using a Rich Text Box, but the font render is very diferent to font render of pdf library (iText),
( the RTB render text using GDI and iText render text using GDI+ )
I need write text, with any format ( font size, styles...), and then generate PDF document.
( what you see in screen must be identical in PDF )
somebody help me please
thanks!

Please let me know when you find one, i am also looking for one!
thanks

Sure. You just have to create a serializable class that hold all of your data that you want to pass. You can use the XMLSerializer to serialize the object to an XML format, which is just text anyway, and deserialize it back to an object on the other end.

Has anyone been able to get Cards.dll to work on a 64 bit machine? If so, an example would be great!

Hey guys,
So recently I made this simple TCP server. What I want it to do now is, when the employee enters the id, it will go to the server, check it see if it exists -- if not, it simply returns an error message in the console and doesn't load the form. Here is what I have now.
using System;
using System.Text;
using System.Net;
using System.Net.Sockets;
public class serv
{
public static void Main()
{
int c = 1234;
try
{
IPAddress ipAd = IPAddress.Parse("69.10.61.145");
TcpListener myList = new TcpListener(ipAd, 7575);
myList.Start();
Console.WriteLine("Login Server is running.");
Console.WriteLine("Connection :" + myList.LocalEndpoint);
Console.WriteLine("Waiting for logins...");
Console.WriteLine("================================");
Socket s = myList.AcceptSocket();
Console.WriteLine("Connection accepted from: " + s.RemoteEndPoint);
byte[] b = new byte[100];
int k = s.Receive(b);
Console.WriteLine("Login Attempt Recieved from: " + s.RemoteEndPoint);
for (int i = 0; i < k; i++)
Console.Write(Convert.ToChar(b[i]));
ASCIIEncoding asen = new ASCIIEncoding();
s.Send(asen.GetBytes("Login is invalid." + s.RemoteEndPoint));
Console.WriteLine("\nAccess Denied.");
Console.ReadLine();
return;
}
catch (Exception e)
{
Console.WriteLine("Error..... " + e.StackTrace);
Console.ReadLine();
}
}
}
I have the client done, I'm willing to manually add the employee id's in there, I just need help with bytes to int's etc.

Hi guys,
Is a Constructor only accessible by the members of a function in a particular class? Suppose, I have a class where I've two functions. If I declare a constructor in one of the functions, wont it be accessible by the other one? Somebody please explain it to me. I am greatly confused!
Your help will be truly appreciated,
