hi,
I work on a computer that is part of a network and uses proxy to connect to net. I cant connect to servers outside my proxy with simple ConnectTo code. I need to know how to make my requests go through proxy. eg,
_socket = new TcpClient("http ://msdn.microsoft. com", port);
does not work.
Thanx.
Ab.

You see you have mentioned "TcpClient/TcpListener" yourself. I have
made pretty nice multiclient, rooms enabled, multi-threaded chat apps
before as experiments, so I have the basic understanding of the
client-server applications. Now I'v been doing that by using classes
that you mentioned which are "TcpClient/TcpListener" and others like
networkstream etc. But one of the app that I was trying to make which
would enable me to be in contact with my home pc anywhere I go,
through my mobile or through a desktop pc. I'm making the desktop
version in C# and *will* make the mobile version in Java :( cuz the
mobile I got uses a symbian OS and no .net is available for that.
Note: You should post your problem to a networking group, like
comp.os.ms-windows.network ing.tcp-ip or
microsoft.publi c.windowsxp.net work_web. This is more a problem of setting up
your infrastructure.
Anyway, so I use the TcpClient to make a connection at an IP say
x.x.x.x, but my problem was, due to which i started this thread, that
I'm on a network and the ip that I give for connection is alway *not
found* or *host unreachable* becuz ofcourse I'm on a network and
directly mentioning, inside the network, an IP which is outside the
network is not found.
So I guess you're talking about a home LAN that is connected to the Internet
by some broadband router performing NAT?
So now I needed a way through which my tcplient
becomes intelligent enough to automatically resolve that IP through
the proxy, but it doesnt.
Your client would talk to the proxy, which in turn talks to the real
application server. A proxy does not resolve addresses for the public. But
anyway, you'll need some network component that is permanently visible on
the Internet, for example by using DynDNS with a compatible router. You
could either expose your server directly (not a good idea) or use a proxy.
Cheers,

Hi,
I'm writing a client/server application in which the client send a series of
screenshots to the server to be saved using the tcpclient.
in most cases the first screenshot is transmitted ok and arrives at the
server but from after that i only a couple of KB from the start of the file
which cases the picture to display only the very top (of the screen).
All the pictures are saved at the client side before sent to the server and

This has been discussed in a prior thread but there was no solution
proposed. Also, using WebRequest is not viable since we need a keep-alive
connection. Can anyone provide any information on using the TCPClient class
(or other) via proxies and whether or not this is possible?

Hello. I'm writing a VB.NET app to check email message counts for both
POP3 and IMAP4. I'm using TCPClient to connect, and a NetworkStream to
send simple commands. It's a very simple bit of code, actually... the
problem is, if the user is behind a proxy, then the Connect method
fails (times out).
How do I get around this? I thought this would be a common issue and

I have an ASP.NET app that has very slow connect times using TCPClient, or
the Socket class, or even calling a COM object that uses C socket calls on
certain similar XP SP2 boxes.
On those boxes, if another connection is made within a couple seconds, it is
fast. Running the same C# code in a console app connects instantly.
Unplugging the network cable allows localhost connections to be instant (?!).

Hi,
I use TcpClient class to obtain a NetworkStream object (via TcpClient's
GetStream() method) in an ASP.Net webapp. This works well if I'm not behind
proxy server but if I'm connected to the network via proxy server I get
"dead network..." error message during the creation of the TcpClient object.
The most strange thing is that the same code is works well with proxy too if
it is in a single C# project. What's the problem in case of...

Hi,
I am developing a C# application to send requests to mail server to check
email addresses validity. I use a TcpClient object to connect to it with the
Connect(String hostname, Int32 port) method.
When I use my application at home I don't have any problem to connect and
get responses but when I try at work, I get the SocketException number 10061
: "target machine actively refused it". I don't have any proxy, maybe a
firewall.

Dear all,
I have a client application which working just fine except in one case: when
it's behind a proxy. I tested it behind MS ISA with enabled Socks service. I
tried everything to make it connect from behind the proxy but, it failed. I'm
using .Net Framework 2.0 and it looks like it does not support Socks proxies.
Is there any solution for this problem? Thanks in advance.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
