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?
Regards

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
that there would be plenty of code out there to demonstrate how to...

i had a problem whom i do not know how to explain.
i was using a TcpClient (System.Net.Sockets.TcpClient) object to send and
receive data to an AS400 socket. Two months ago it started to work slowly,
about 4 seconds between send and receive. In our production environment with
hundreds of transactions it was truly costly.
a while ago i changed de TcpClient object. Now i am using a Socket
(System.Net.Sockets.Socket) object and it...

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 (?!).
Running the same ASP.NET app on...

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...

Is it possible to extend a Web service proxy so that it understands an HTTP
refresh page?
Explanation:
* The Web service proxy was autogenerated by Visual Studio .NET 2003
from the Web service's WSDL. It inherits from
System.Web.Services.Protocols.SoapHttpClientProtocol.
* The Web service is hiding behind a load-balancing content switch

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.

Hi
I rewrite an old C Programm to C# (Framework 1.1) - it is an easy FTP-
Client.
I create a "Command-Channel" using TcpClient, a "Command-Reader" and a
"Command-Writer"
to speak with the FTP Server
coChannel = new TcpClient(this.HostName, this.Port);
coReader = new StreamReader(coChannel.GetStream());

I found an example online and when I tried repeating it with the proxy I
normally use for my browser, I get errors.
What I do is this:
WebProxy proxy = new WebProxy("http://www.autoconfig/pac", true);
That url is exactly what I enter into Firefox advanced settings to get
beyond the office firewall here, but C# does not like it.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
