I'm trying to send a packet of binary data to a UDP server. If I send
a text string, it works fine. If I attempt to send binary data, it
sends a UDP packet with 0 bytes of data (just the headers). I can see
this because I'm running Ethereal and watching the packets.
I'm defining the packets as shown below:
$text_msg = "Hello, world\r\n";
$binary_msg = chr(0x01).chr(0x02).chr(0x03).chr(0x00).chr(0xA0);
$binary_msg_size = 5;

My application requires sending a large piece (~2MB) of data to
several devices on a network via TCP sockets. I have experimented with
different methods for doing this and this has raised some questions
about the implementation of Python sockets.
(both methods use blocking sockets)
Method 1: Calls socket.sendall(data) for each device in sequence, all
in a single thread.

Hi,
I am sending an email from an asp page. Besides sending an email to sender,
I am sending myself a BCC also. Out of 100 emails sent, about 5 recipients
received a blank email (no text in subject and body). The BCC of all these
emails that I sent to myself were fine. When I send email manually to these
5 recipients they receive it well.
I have pasted my code below. Can someone give me a clue as why this could be
happening? Is...

Hello Fellow Developer,
I use the System.Net.Sockets to send/receive data (no
tcpclient/tcplistener), I made a receivethread in my wrapper, the
receivethread loops/sleeps while waiting for data and then fires a
datareceived event.
Within the waitingloop there is a timeout function, but I want the the
'last-time-socket-used' variable set when the socket is finished sending.
When I send by System.Net.Sockets.Socket.Send(buffer()) (<--this...

Does any one have any suggestion of Sending Files over a Network ?
using TcpClient class in C#.
I need suggestions on transferring huge files ( > 5MB) reliably over
the stream . Also any kind of files could have to be transferred .ie
Exe , mp3 , dat .. any kind . Do i need to convert these files ? When
i normally send text files i convert them to Ascii bytes using
Encoding.Ascii.getBytes() . Will it work with Exe files and all others

Right guys.
(I would like a solution to this in VB6 as this is what our needy app is
written in, but any solutions that involve .NET would be much appreciated
likewise as I could instantiate them, otherwise please forgive the
crossposting.)
I'm sure I've seen posts here before criticising the practice of automating
outlook for the purpose of programatically sending email, on the grounds that
it's naff. Well now we're really landed in...

Hi,
I am trying to construct a WSE 2.0 security SOAP request in VBScript on an
HTML page to send off to a webservice. I think I've almost got it but I'm
having an issue generating the nonce value for the UserName token. Is it
possilbe at all to do this from VBScript (or jscript?)? I know I will be
limited with what I can do with the SOAP message. Eg/ can't sign/encrypt it
etc.
Thanks,

I'm using MSW XP Pro with Python 2.4 to develop but production will be Linux
with Python 2.3. (could upgrade to 2.4 if absolutely necessary) I can also
switch to Linux for development if necessary.
I am writing some python to replace proprietary software that talks to a
timeclock via UDP.
The timeclock extracts the sending port from the UDP header and uses that
for all response messages.

by using FTP i can send files to server using vb.net.
if the file is big, then it will take some time to complete the sending process to server.or if we were sending 3-4 files to the server one by one,then whethere we can show the progress of each file sending to server in progress bar. so that the FTP clients can see the progress of file sending to the server.
any idea how we can do this to show the progress of each file sending. if we...

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
