TCPListener Website Server?
Aug 18, 2009I have just created a website server with Visual Basic 2008. I want my server to have the famous "resume donwload" function... but i dont know how the HTMLHeader should look like when its resuming a download.
Here is how the header normaly looks:
HTMLHeader = _
"HTTP/1.0 200 OK" & ControlChars.CrLf & _
"Server: Website Server " & My.Application.Info.Version.ToString & ControlChars.CrLf & _
"Content-Length: " & GetFileSize & ControlChars.CrLf & _
"Content-Type: " & GetContentType(StringRequest) & _
ControlChars.CrLf & ControlChars.CrLf
TCPListener And Server - Authentication Process?
Mar 11, 2010I am creating a simple program. (soon to be vastly complex) that is connecting to a server, and sending an authentication code to connect. I got the connection part, but what keeps breaking up is the method of authenticating. I have the entire authentication process in a while loop, so that it will keep going until it receives the authentication reply from the server (an OK-002938, or what ever client number the server decides.
This is my client code for the event:
Private Sub CONNECTSERVER_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles CONNECTSERVER.DoWork
Try
If network_client.Connected = False Then
network_client.Client.Connect(My.Settings.service_address.ToString, My.Settings.service_port.ToString)
[Code] .....
The client side is flawless. But the server side, works, but it doesn't continue past storing the bytes into a container...
Communications :: Basic Server With TCPListener - Not Responding
Apr 3, 2009I am trying to build a sort of basic server thing and I cannot seem to get the thing to work properly. I have a client and a server. The client sends a string, the server receives then replies. I cannot get the server to continue responding.
It works in one direction Client -> Server
But because the server is continuously listening the form becomes not responding, thus I cannot send messages from the server. Although it says that its not responding I know that it is just using all of the processing for listening because when I send something from the client the server responds, just the form is stuck because of the listener.

Oct 1, 2008I've been creating short test apps repeatedly to try to understand some of the concepts in VB.NET.For the most part it has been illuminating.I read Bucky's .NET knowlegebase tutorial on passing objects as parameters to newly created forms.

Tcplistener / Tcpclient Over LAN
Apr 22, 2012I am creating an application that will be talking over the LAN (and eventually, WAN) which uses the Tcplistener and Tcpclient objects.Now, I have this working absolutely fine locally using the loopack address although when I change the IP of the listener to 0.0.0.0 (listening for all IPs) and the IP in the client application, to the IP of the server, it throws an exception when connecting. The client says something along the lines of the the server has rejected the incoming connection. So i disabled all firewalls temporarily but I still have the problem.I have ran netstat on the server which clearly shows that it is listening for an incoming connection on 0.0.0.0. [code]

Out Of Memory Exception With Tcplistener?
Oct 26, 2011 I have an application that listens for connections asynchronously. When a connection comes in, it spawns a new thread from the callback method. This works fine for up to about 13 simultaneous connections then it dies with an out of memory error. The threads that are spawned just do a CHAP handshake and authenticate then go in to a command loop where they sleep until a command comes in or a timeout occurs. I have pasted the code below. Sometimes it will not throw an error but the thread never gets spawned although the connection is accepted.
Code:

Ive been able to successfully load a shortcut file and parse its Lnk File Structure but now Im on the Shell Item ID List structure but I cannot find the Structure of the ITEMIDLIST anywhere
Furthermore I know I could use the Windows script object, but this is a dependency Im trying to avoid if I can, hence writing my own Shortcut class.

TCPListener - Listen To Particular IP On Specific Port
May 26, 2009How can I ask my tcpListener to listen to particular IP on specific port? I want my tcpListener to listen to the local IP of the machine. I can get the ipaddress of the pc using Dns.GetHostAddresses(). But, if pc have multiple ip's how can I know which ip address is correct? From tcpClient class I am connecting to the server. So, I know the server ip and so I want to specify ipaddress to my tcpListener class to listen on.

View 1 RepliesVS 2010 Checking For An Error Before It Happens [TcpListener]
Aug 10, 2011Basically, in my Tcp Library I'm working on, whenever the system is told to "Stop", the OnClientConnected() Routine fires off, which is only raised under two circumstances: When a Client connects (obviously) When the server is told to shutdown
Now, the first one is handled just fine. But the second one is not. In fact, it has caused me a great deal of headache because it keeps throwing exceptions on this line in particular:
Dim _tcpClient As System.Net.Sockets.TcpClient = _tcpListener.EndAcceptTcpClient(IR)
When I hover over while debugging, I can see a few members that reveal exception data I could utilize; but unfortunately those members are private and I don't want to utilize reflection unless I have to since it could slow down performance where there may not be a real reason to.
I have thought of writing in a Boolean check to see if the server received a shutdown signal and that would indicate that it's time to not accept anything, but I want to avoid that if possible.
Is there any way to see if the TcpListener is no longer accepting connections and has had .Stop() called without reverting to catching the ObjectDisposedException that is raised? (because the Socket that is "accepted" is actually a disposed one)
