ah, my bad

Update:
- It won't crash anymore, except if you fill in a fake IP, which isn't my problem.
- I added a button to check if a CO server is on.
- I am still working on this.

It checks if a server is online and you can scan any random port at any random IP to see if its open or closed. (It has to be open at the moment you scan, so the person has to run the program that keeps it open, e.g. WampServer.)

If he doesn't obfuscate it its not my problem.

I used a .NET Reflector. His code isn't that hard of work so don't think it will take long. ( not that im saying you did a bad job, just telling this guy that its not much to steal )

This is off-topic, but add my msn , and I'll do what I can.

~9 views, and only 4 thanks, please hit the thank button, It took some time~

@Pete, I don't think its respectfull to reflect someone's released .exe and than release the source on the same forum, however, this is my opinion, I've protected it this time, I didn't except anyone to do that though.

[~Yuki~]

decompiled. Thanks

"@Kinshi" ? What did I do? I haven't even posted in this thread (till this post).

[killermickle]

About it crashing with a fake IP, does it have a timeout function.
And does it split the IP and check all the values are <= 255?

[Basser]

Yuki ill msg u on msn about this. Another update 2morrow, or a new release.

I thought that, for a socket to connect, there would have to be a server listening on the end of the port and address specified. If so, is "Port Scanner" really a valid name for this program?

Your program wouldn't for me (for reasons I know of), so I wrote one in Java:

/*
 * @ServerStatusChecker.java
 * 
 * GUI which allows the user to input an Ip address and port.
 * 
 * This program will notify the user if the server on the given
 * address and port is listening.
 */

package serverstatuschecker;

import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.net.Socket;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JTextField;
import javax.swing.SwingUtilities;

        addrLabel = new JLabel("Ip Address:");

        doItButton.addActionListener(this);

        add(addrField);

    /**

            public void run() {
                new ServerStatusChecker().setVisible(true);
            }
        });
    }

    private JLabel addrLabel, portLabel;
    private JTextField addrField, portField;
    private JButton doItButton;
}

It is probably better and more reliable than yours, but I do not know that for a fact.

Your program wouldn't for me (for reasons I know of), so I wrote one in Java:

If you're going to code it in Java, you may aswell use PHP.

mysql_connect ("127.0.0.1", "root", "password");
mysql_select_db ("coproj");
$con = fsockopen($host, $port, $errno, $errstr, 1);
error_reporting(0);
if($con)
	echo 'Server Status:&nbsp;<font color="green"><b>Online</b></font>';
else
	echo 'Server Status:&nbsp;<font color="red"><b>Offline</b></font>';

Please stop posting new scripts, this is a release not a question.
