Yes, I do get a 150 response once the STOR command is sent. I have no problem with the PASV command at all.
This is what I do for PASV (this works):
1. Connect to FTP server w/ Username/password
2. Send the PASV command and read the response from the server
3. I parse out the IP Address and Port sent by the server in step 2
4. Create a new socket with IP/Port and connect to it.
5. Send the STOR command
6. Send bytes to upload file on the connection created in step 4
This is what I assume I should be doing for PORT:
1. Connect to FTP server w/ Username/password
2. Retrieve local IP and generate random port #
3. Create new socket with IP/Port from step 2, Bind and Listen
4. Send the PORT command with the IP/Port generated in step 2 (I receive "200 Port command successful" from server)
This is where I'm unclear on what to do next. I'm assuming that the server will automatically connect to the port I just sent, but it doesn't seem to.
5. Send the STOR command (receive 150 response from server)
6. Upload file on connection that I'm listening on (Error occurs here).
The reason I'm trying to do it this way:
Our automated FTP program has been failing to send files to one of our clients in Passive mode. After we contacted them they asked that we try sending the files non-passive. What I find odd is that we receive a response from their server when sending the PASV command, but we can't connect to it. In fact, we can't even ping it. So, you might be right in that it could be a firewall issue on their end. Nevertheless, I was still tasked to get Active file transfers to work, but can't even do it on our local servers.
Any thoughts?
Thanks, Eddie

Are you writing a FTP server or a client? Your CreateActiveDataSocket() function attempts to listen on the specified port and host and then immediately does a SendCommand
Assuming you're writing a client, the correct code would be
private void ConnectToServer()
{
Socket socket = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
socket.Connect(new IPEndPoint(Dns.Resolve(Dns.GetHostName()).AddressList[0], 20));
}

Thanks Senthil. I'm writing an FTP Client. Assume that I'm already connected to the FTP server. After connecting, I want to FTP a file in Active mode. In order to do so, I create a new socket with my local IP and a random port and listen to it. I then send the "POST 192,168,xxx,xxx,xxx,xxx" command to the server which has my local ip and random port I just generated that I want the server to connect to. The problem is that it doesn't seem that the server ever connects with the IP and port that I sent, hence, the error in my original post. How do I make the server connect to my IP/port? I know I'm missing something.....
Thanks again for your help!
Eddie

I've never heard of the POST command. It doesn't seem to be a standard FTP command?
AFAIK, you don't need to create a local server socket on a random port and list on it. And the server won't attempt to connect to your client, it's the client who'll connect to the server.

i want the title bars of both forms to show active at the same time. In WindowsXP default, both title bars would be blue instead of one being blue and the other form fading to light blue, it is possible (overriding windows messaging) i know, but how?
Can someone indicate me how?

Actually I don't think it is possible at all. You could paint your title bar the same color even if it is inactive, but getting Windows to paint the caption as active when it isn't, no way. Only one window is active by definition.

Hi, I have a user thread and I need to tell it to run some code in the GUI thread. I was thinking that maybe I would use SendMessage and create a message handler for this but it sounds like more of a C/C++ way of doing it. Is there something in C# line this? Kind of like java has SwingUtilities.invokeLater()

Actually SendMessage is not directly implemented in the CLR.
You should use the BeginInvoke to call code in the UI thread from another thread.
Google for BeginInvoke and UI or read this article: http://www.codeproject.com/csharp/winformthreading.asp[^]

You can use BeginInvoke and Invoke on the System.Windows.Forms.Control class.
This[^] article explains the gory details.

Hello,
I encountered a strange problem and I do not know what is causing it.
I created an empty form, added a tabs control to it and set the tab control
dock style to fill. Then I added three tabpages to it. To the first tab page
I added three buttons. The first button's click handler would set the tab
control's tab alignment to TabAlignment.Left and the second buttons click
handler would set it to Bottom.
I added mouse enter and mouse leave handlers to the third button. Whenever
the mouse would enter the button, I would change its background color to
yellow. When the mouse leaves the button, I would set the color back to its
original state.
Now, when I start the form, the mouse enter/leave events work great and
everything is fine. However, once I change the tabs alignment by hitting one
of the first two buttons, the third button no longer fires it's mouse leave
event and only fires the mouse enter event once. The mouse enters and mouse
enter fires correctly, but it seems that the mouse leave event has been
unregistered when the tab control's tab alignment changed.
Does anyone know what can be causing this behavior and how to fix/avoid it?
Thanks,
-Flack

I'm attempting to connect to a MySQL database from my ASP.NET application (c#). Here's my code:
string connString = "Database=games;Data Source=http://[my server's IP]/mysql;User ID=group; Password=" + strSystemPasswords[3];
conn = new MySqlConnection(connString);
conn.Open();
The database is contained in the mysql directory under the web server's root. (I added a space between group; and Password to prevent a smiley.)
When I run the code, I get the following error for conn.Open():
"The requested name is valid and was found in the database, but it does not have the correct associated data being resolved for "
I've researched the problem and have found the standard answer is that the address can't be resolved. However, I am assuming that this is not the problem in my case, as I can navigate to that exact address with my web browser. But I haven't found any alternate causes for this error.
Any suggestions?
Thanks for your help!

Your datasource is local to the server. ASP.NET is a server-side only technology that generates HTML for a client. Change your "Data Source" so your code is looking for it local to the server filesystem, not over an http connection.

Ok, I'm trying to capture text from a texbox inside of another program. In other words, I have a window handle of an exterior program. This program contains a textbox. I would like to capture that text. Is there a set of API commands that would enable me to do this? I've been looking on MSDN for a while and haven't found anything. Any help would be greatly appreciated. Until then, the searhc continues...

Try : <a href="http://www.pinvoke.net" rel="nofollow">http://www.pinvoke.net</a>[<a target=_blank title='New Window' rel='nofollow' href="http://www.pinvoke.net">^</a>]
|

Use the win api SendMessage twice first with WM_GETTEXTLENGTH then again with WM_GETTEXT. GO ahead and try it yourself with the example at pinvoke.net. If you still can't get it to work just let me know.

I have a class "Person"
Person has 2 propertys:
Name
Adress
Person p = new Person();
p.Name = "Mike";
p.Adress = "Anywhere";
Now I have a problem with adding it to the Combobox.
In the Combobox list, I only see [namespace].Person all the time, not "Mike".
There are possibilities through indexes, Hastables ... and so on..., but are these the only possibilities ?
Is there a way to add the object to combobox directly ?
|
|
|
|
|
You could override the ToString() method of you Person class.
public override string ToString()
{
return this.Name;
}
/cadi

The problem is still the same. with ToString, I only put the string in the combobox, not the object itself.
So the object should be added into the combobox and the Combobox Item description shouldn't be the objects name.
|
|
|
|
|
No, you do not!
You add the object and the Combobox uses the to String method of the items to display a text.
Try this:
<code>
private void Form1_Load(object sender, System.EventArgs e)
{
this.comboBox1.Items.Add(new Person());
foreach(object o in this.comboBox1.Items)
MessageBox.Show(String.Format("Item is of type {0} and is the persons name is {1}",o.GetType().FullName, (o is Person) ? ((Person)o).Name : "not a person") );
}
it works fine in my test.

cadi said it right. ComboBox actually calls ToString() method of it's Items. For your class default ToString() returns string representation of type. When you override ToString(), combobox will display Person.Name field, but e.g combobox.SelectedItem can still be instance of Person.

Thx, this works.
I added .ToString directly before.
