Hi
I want to send an ASCII character string / stream to an IP address.
I basically have 6 barcode printers, and a web interface.
Depending on what is entered on the web page, will determine which printer
the label is printed on (ie. which IP address the ASCII string / stream is
sent to).
How can I send an ASCII string / stream to an IP address??
Thanks

Paul,
I'm going to assume that you already have some way to pass information
worked out, either TCP, UDP, or something else. If this isn't so just
respond and I can help with that, but for now, to keep this short,
here's how to do what you want.
You want to parse your ASCII string into a byte array. Try this
byte[] data = Encoding.ASCII. GetBytes(yourAS CIIstring);
Now you have your ASCII string in a byte array that can be written to
the network anyway you choose. Does this help? If you wanted to know
how to actually send this byte array let me know.
Hi Justin,
Thanks for the help
Yes - do you have some code (any, but C# preferred), that will send this
string to an IP address??
Thanks
Paul

Paul,
The wau Vadym shows here is exactly the way you want to do it, provided
that your webservice is running on port 11003 and accepting TCP
connections. As for TCP, it probably is, but it could be running UDP.
As for the port, that's different for every web service, and your
webservice may also be accepting transmissions from several ports. Try
what he showed, but with using ASCII instead of UTF8, and if it doesn't
work just reply to this and we'll try something else.

Hi all,
I'm trying to send a null character as a string delimiter through a
TcpClient (code below). It's to connect to this poker bot room:
http://games.cs.ualberta.ca/webgames/poker/bots.html
My code is as below, but I never get a response. I'm assuming my
transmission is ending at the null character (the debug statement certainly
only outputs up until the null character). Any ideas?

Hi, I'm able to make connection to a server using socket connection.
However, when I send a command string the server just ignores it. All
command string needs to start with "0xF9" at Byte 0. During the run-time
debug, I see it to be "u" with a "~" on top of it. Is that OxF9? Can
someone tell me what I'm doing wrong?

What you have to implement
You have a message that can be sent on a port. Before sending the message you have to encode the
message to ASCII or Unicode as hexadecimal. Sending the message over the network as a continuous
string stream is quite simple. The recipient simply has to decode the hexadecimal string and will know
what the message is.
The problem...

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.

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,...
