Hello all, I need to be able to detect if there is an active available
Internet connection in my VB6 program. In my program I'm using the Internet
Transfer Control to transfer some files by HTTP, but as it stands now,
there's no code to detect if there is in fact a network connection available
before I try sending.
Is there some easy way...

Hello -
I'm writing an application that will be used on "sometimes connected"
devices (laptops, tablets).
In C#, what is the best way to detect whether a network connection is
present? I'd rather not rely on a network request timing out - the detection
process must be very quick.
Thanks in advance,

I am using the asynchronous send/receive methods of the Socket class.
When the remote end closes the socket, the callback for receive is
called and EndReceive returns 0.
Socket.Connected still returns true at this point, which I know is
expected behavior, so when I reach this state, I begin sending on this
socket every few seconds until...

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...

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...

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. ...
