Hi,
I have a project using the TcpClient and its associated NetworkStream.
Everything works well except for one condition which I haven't found any
information about dealing with:
How do I detected when the socket connection was closed on the
server-side?
That is, if my client connects to the server and everything is initialized

I'm facing a problem where I need to verify that my windows forms application has access to the internet before it can do anything. Currently, the only way I can think of is by creating a HttpWebRequest and point it to the specified URL I wish to connect to later on, and if that throws an error, I know I don't have an internet connection. Is this the best method for detecting an internet connection, or is there some sort of routine that I need...

I'm having trouble finding example code to detect the presence of
an Internet connection. It doesn't seem to be a very frequently
asked question, as all I need is the answer yes or no (is the user
connected or not). I'm not interested in speed detection or any
other aspect of the connection, just its existence or not. The
reason is to be able to intercept link clicks on a CD-based set
of HTML pages and pop up a warning if there is no...

I have a utility that I want to only run when a network connection is
present.
I want to plan for the situation when
someone unplugs their laptop from the network and takes it into another
room. My process requires a connection and I don't want it to blow up when
one does not exist.
I have tried using the "wininet.dll" API, but it still tells me I am
connected when I am unplugged from the network. Has anyone else had the

I have an instance of a TcpClient using a NetworkStream and I want to be able to detect when the connection is lost (or cable unplugged). What is the best way of doing this?
I don't want to use getByte because it reads from the stream.
I tried inheriting TcpClient to access the protected function Client.Connected but this returns true even when the connection has been lost.
Any help is appreciated.

According to HTTP/1.1 specs, a client should only have two connections open
to the host at a time (which can be changed by browser users, of course).
When using xmlHttpRequest connections, is there any way to detect that the
request is queued?
I did some tests (see "Queued Requests" at
http://www.ajaxtoolbox.com/request/examples.php ) and it looks like
readyState 1 is fired immediately after the request is made, even though
it's not...

Hi All,
I've tried to RTFM this and am having no luck. First off, I am using
Mac OSX 10.4.7 with python 2.4.2 from fink. I am trying to connect to
a server that should be rejecting connections and I was surprised when
it did not throw an exception or do something otherwise equally nasty.
It just connects and never returns any data. First, the proof that
something is there and rejecting the connection (or is it that this

Hi group,
I've written a client/server application, using the dotnet sockets.
In my server, I have a thread waiting for messages with :
ret = currSocket.Receive(buffer, 1024, SocketFlags.None);
When the client exits, I close the socket with a specific message
(like "end") and the thread terminate in a proper manner, but If my
client crashes, the server is still waiting for receiving data, and

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.
