Flatten to string for sending through TCP/IP contains CRLF characters

Hi,
I'm using a 'flatten to string' function to send some data through TCP/IP.
To minimise delays, I use the CRLF mode so that the receive function returns as soon as it receives a CRLF sequence (termination character).
I noted that every now and then only part of the data is transmitted because the flattened string itself sometimes (albeit rarely) contains CRLF characters.
I was wondering if this is correct behaviour, or if I'm missing something.I expected flatten to string to produce pure ASCII strings without special characters.
Now I first have to scan the string and replace possible CRLF characters by some known series of characters and do the opposite on the receiving side, and hope that this particular sequence never occurs.
Any comment is appreciated,

Hi,
thanks for the feedback. I'll use the way you describe, by first sending the number of characters to expect.

Make sure you are consistent with the format for the number of butes. That is, always use an 8, 16 or 32 bit value. Which one you use is up to you and will depend on the size of your data. A 32 bit value is the most common size to use. Anyway what I am basically saying is that if you are inconsistent with what size number you use for the size you will get inconsistent results when you read the data since you will be interpretting the size incorrectly some of the time.

Sending mail to domains containing extended characters?

Hi!
I'm having trouble sending e-mail with cfmail to domains
containing characters like å ä ö. In mail.log I get
the following message: "508 5.5.2 Illegal character in address".
Is this a bug or a setting somewhere in the Administrator?
Thanks in advance!

According to this:
http://en.wikipedia.org/wiki/Domain_name_system#Internationalised_domain_names,
it's legal to have those sort of characters in a domain name,
but not a
host name.
But according to this:
http://java.sun.com/products/javamail/javadocs/javax/mail/Address.html,
it
sticks to RFC 822 (
http://www.ietf.org/rfc/rfc822.txt),
which doesn't seem
to differentiate between the host part and the domain part of
an address,
and only allows for ASCII 0-127 in the domain name.
So the bottom line is those domain names - for the purposes
of internet
email addressing - aren't actually legal. So - strictly
speaking - it's
correct for CF to reject them.
I would say you're screwed, unless you can find some
alterative emailing
system (not <cfmail>), and use that. But then again,
the alternatives
could quite possibly disallow those addresses too.

How do I read/write many matrices through TCP server?

I'm trying to modify the simple data client and the simple data server program in example in LabVIEW6i. How do I send a 2 dimension nummeric matrix? and also how do I send many numeric matrices at a time?

The problem here is that at the receiving end, one cannot know how many
bytes to read before unflattenning into the datatype.
A method that works for *any* datatype (and any data transfer mechanism):
Flatten the data to string.
Flatten again the string to string; this adds a string lenght (U32) header
to the string.
Send the string.
When receiving data, first read 4 bytes and convert to U32.
Read this number of bytes.
Typecast the string to the expected datatype.

Can we send a tcp/ip message from a specific port to the client

Hi All,
Iam currently trying to send a tcp/ip message to a remote machine on a specific destination port. For each tcp/ip message that iam sending iam able to figure out that the source port varies each time. So I wanted to know if it is possible to maintain a source
port for sending a tcp/ip message just like a destination Port. You can see my code below for reference:
TcpClient client = new TcpClient();
client.Connect("xxx.xxx.xx.xx", 2024);
NetworkStream clientStream = client.GetStream();
ulong refno = GetSessionID();
DateTime dt = DateTime.Now;
string str = dt.Year.ToString() + "-" + dt.Month.ToString() + "-" + dt.Day.ToString() + " " + dt.Hour.ToString() + ":" + dt.Minute.ToString() +
":00";
ASCIIEncoding encoder = new ASCIIEncoding();
string Input2 = "<STX>Inquire<US>REF=203.163.253.55<US>RQN=" + refno.ToString() + "<US>DTE=" + str + "<US>ACI=5274<US>ACE=C<US>ACS=A<ETX>";
string Input3 = "<STX>Inquire<US>REF=203.163.253.55<US>RQN=" + refno.ToString() + "<US>DTE=" + str + "<US>ACI=5274<US>ACE=C<US>ACS=A<ETX><CHECKSUM>";
int length = Input2.Length;
string hexValue = Input2.Length.ToString("X");
string hexValue2 = length.ToString("X");
// string Input = "\x02 Inquire\x1F REF=203.163.253.55\x1F RQN=" + refno.ToString() + "\x1F DTE=" + str + "\x1F ACI=5274\x1F ACE=C\x1F ACS=A\x1F \x3 \\x" + hexValue2;
string Input = "02Inquire1FREF=203.163.253.551FRQN=" + refno.ToString() + "1FDTE=" + str + "1FACI=52741FACE=C1FACS=A1F3" + hexValue2;
byte[] buffer = encoder.GetBytes(Input);
clientStream.Write(buffer, 0, buffer.Length);
clientStream.Flush();

Hi ram,
The TcpClient class has a constructor that receives an IPEndPoint instance, this is the local EndPoint.
The IPEndPoint consists of two parts, the IP address and the port to use. you can specify the local port with this parameter.
IPAddress ipAddress = Dns.GetHostEntry (Dns.GetHostName ()).AddressList[0];
int port=9999;
IPEndPoint ipLocalEndPoint = new IPEndPoint(ipAddress, port);
TcpClient tcpClientA = new TcpClient (ipLocalEndPoint);

My Tcp/ip multi-client server is not passing the data string into the flatten to string vi

I am using labview Multi-connection cleint and server to build my own multi-client server connection.
The problem i am having is that the data does not get through the flatten to string vi. Would anyone be kind enough to tell me why is that happening? and what I do to fix it.
Attached code . My goal is to send data to the client via tcp/ip and use the data to perform certain task.
Thanks a whole lot

Sending file through TCP/IP

Hi all,
I would like to know whether LabVIEW is able to send file through TCP/IP. Can anyone please enlighten me on this. Thank You
Rgds

Hi taytay,
Of course it is possible !
Go to function palette >> Communication >> TCP ; I have never used them but here they are.
Go to Help >> Find examples.. and search for TCP, you'll find example code
You can also purchase the "internet toolkit" that provide ready to use FTP VIs to send or copy simple/multiple file(s).
Hope this helps.

I'm using UDP Send to send an 1D arry with 3 elements. On the other side I'm using UDP Read to read my 1D arry with 3 elements but they are coming in a string for somereason.

Using UDP send to send a data across a connection to UDP read data by using a Port and IP. The data I'm sending is 1D array with 3-elements. I'm taking the 1D array on UDP send side and converting to a string before I send out b/c UDP can not read an array. So I'm using "Array to Spreadsheet String" to and sending it.
On the Other Side I'm using UDP Read to read the data by listing to a port and capturing the data. I'm receving the data but they are in string format instead of 3 spreate elements. So how can I change that to 3 elements instead of string?
Any help would be grea
tful,
Thanks

It is usually easiest to take any data and flatten it to string before sending.
On the receiving side, use unflatten from string, using the original data type as template.
You can do this with any kind of data (array of strings, array of numbers, booleans, complicated clusters, etc, etc), see attached code image.
Flatten and unflatten is very efficient and does not change the data. For example there is no rounding or formatting loss.

Provide simple example for Arbitrary data sending through NI4551(DSA)

We Converted NI-DSA function palette
in LabVIEW under Application
Examples>>Advanced>>Arbitrary Output Example.
But, We not exactly getting arbitrary wave. Our arbitrary data is correct. I think there is a problem with FFT settings. So Please Provide simple example for Arbitrary data sending through NI4551(DSA)

Hello Sateesh!
First, what versions of LabVIEW and NI-DSA are you using. I have been searching around for the example you are refering too and I am not able to find it. Are you creating and arb. wave in the frequency domain and then performing an FFT to get it to the time domain? Next, remember your wave will only be as exact as the AO specs. of the hardware...
The output conversions occur simultaneously at software-programmable rates from 1.25 to 51.2 kS/s in increments of 47.684 µS/s. The analog output circuitry uses eight-times oversampling interpolators with 64-times oversampling delta-sigma modulators to generate high-quality signals. Software-programmable attenuation of 0, -20, or -40 dB is available on the output channels. The PCI-4451 has excellent amplitude flatness of ±0.2 dB within DC to 23 kHz, and a THD of -90 dB at 1 kHz.
Now, as far as obtaining other examples If you use the LabVIEW example finder and goto Hardware Input and Output>>Traditional DAQ>>Analog Output. I would also in the lower right hand corner of the Example Finder select your 4451 this will show you all examples that work with your hardware. I hope this helps a little but please give me more details we will go from there. Have a great day!

Communicate a PC with GPRS module through TCP/IP

I want to exchange data between a PC and a GPRS module.
One problem i have is that my PC is on a local network and the IP my computer has, is the local IP. The server has a different IP through we connect to the internet. Which IP I must use and how?
I know almost nothing about TCP/IP (i have use the Labview TCP/IP functions successfully at our local network) and i would like to ask for informations. I know it is a little irrelevant with Labview, but as there are many users who uses GPRS modules, i would like informations about how to connect a GPRS module through TCP/IP. Simple examples will be the best.
Any informations, links, recommended books, will be highly appreciated.
Thanks

Thanks for answering Rolf.
To be more clear : i have a GSM/GPRS module (like the well known Wavecom's modules (or Falcom, Telit...)). They accept AT commands and they have a D-sub-9 serial connector. They connect to serial port of the PC. I want to connect to the internet with TCP/IP (by sending AT commands). But i can not find any manual..! The module have some commands for TCP/IP but no explanation or examples. Those modems have no drivers, they accept only AT commands.
For example i have to set APN and IP Address which i don't understant what i should write to. It is independant of Labview but i do not know where to look for information.
If someone knows anything similar please reply.
In that case what I wrote applies fully to you. You do not want to communicate with the modem from LabVIEW itself. You want to use TCP/IP and that means using the Windows socket library that the LabVIEW TCP/IP functions access. The modem then needs to be installed in the Windows system as a dialup adapter. There is really no other way to use a modem, GPRS or not, as TCP/IP communication path. Trying to implement TCP/IP,SLIP/PPP and all that in LabVIEW would be a many man year project with lots of problems and the likely chance that it will never fully work.
So get your modem to work under Windows so that you can use your browser to view some internet pages and once that works you can also use the LabVIEW TCP/IP functions to communicate with whatever is there.
Direct communication to the modem through AT commands would only make sense if you wanted to access the SMS facilities in that modem instead. Even that is not exactly trivial as I can attest to, especially if you want to make it work with more than one GSM modem type.
Your modem manufacturer should be able to give you the necessary modem initialisation string to put your modem into the right GPRS mode and your mobile phone network provider should be able to tell you the dialing number to fill in the dialup configuration. No need to do anything else!
As Wiebe explained rasdial.exe would then make it possible to connect to the internet under LabVIEW control.
All in all it's doable but I have spent many hours to get it working last time I did. A few of those were spent waiting on the line for the support persons of the mobile network provider to answer my calls and then playing the ping pong game to get a person that actually knows what a computer is and that it's actually possible to connect a modem to it to use their services.
