Receive binary, want to println as ascii
Someone please help me. I am writing a Multicast receive program. How can I code when it receives the binary and println it as ascii? Such as
while(true) {
DatagramPacket dp = new DatagramPacket(buff, buff.length);
ms.receive(dp), // ms = new MulticastSocket(port)
(Right here, how to do the Seconds ,data type is Float, 64 bits)
// I am okay with Alphanumeric
String s = new String(dp.getData());
System.out.println(s);
I am appreciated your reply.
Try to use the charset along with the String constructor. use the following constructor
public String(byte[] data, int offset, int length, String encoding)
throws UnsupportedEncodingException
U can use US-ASCII ir UTF-16.
try it

Receiving binary IDOC via Queue and convert it to XML-IDOC
Hello,
we are focusing the following scenario:
We receive an plain, binary IDOC in a MQSeries Queue. We want to pick it, transform it and place it into R/3 (of course using XI 3.0). Afterwards the other way around.
I know the Howto for the ABAP mapping from XML-Idoc to plain IDOC. This may also work for our scenario. Do you agree?
The other way around is more difficult. I assume that - since the IDOC adapter resides in the ABAP stack - we cannot re-use an existant adapter module in the JMS adapter. Right?
I heared about JCO capabilities of "xmlizing" Idocs - but did not find hints within the javadoc. Anyway, would this really be the preferred way - writing an user exit for the adapter using JCO - to handle this? There must be a way to do it better, must it not?
How did you guys face this problem - I think its a common one...
Any starting points for a discussion are appreciated....
Greets,
helgeHi Helge,
For the conversion of the incoming flat message, one could imagine a similar ABAP mapping as the one described for the XML->flat message conversion. The function module IDX_IDOC_TO_XML could be a good starting point for your search.
To perform conversions in the Java stack (e.g. in an adapter module) might be a quite complex task since you first have to get the IDoc metadata. And there you cannot reuse existing function modules.
Best regards

Hi all,
I recently bought blackberry passport and wanted to know whetner there is any fuction that I could receive calls only from pre-listed numbers. Previously I used samsung galaxy note and there was block mode which allows me to block all the call except pre-listed numbers. I know that there is a fuction which block all the call in blackberry 10 os. sometimes I don't want to receive any call but still need to be connected with some important people like mom or wife.... Please help me.
Many thanks,
JY
Solved!
Go to Solution.you can block all or none on the device but there are several call blocking apps in BlackBerry World that you can use

Serial receive - ignore \r\n CR LF ascii codes
Hello,
I am trying to read an array of characters including carriage return and line feed into one array into labview. I receive the command then wait x miliseconds until all data has been received and then read all data in the buffer using the serial read function. An example sequence of series of characters is as follows:
printf("RTCC time date\r\n35:6c:53\r\n0d/02/cb\r\n")
I need to receive this exact set of characters and store them into one array in labview. It appears that labview automatically breaks from the read routine when it receives the Carriage return or line feed code. Which, when writing to an array only gives the characters up to the line feed, then overwrites them upon exiting and returning the receive the next set of chars up to the next line feed. Which, in this case would require to have 3 separate arrays in order to store all of the data. Which ends up looking like this:
array1 "RTCC time date\r\n"
array2 "35:6c:53\r\n"
array3 "0d/02/cb\r\n"
It seems like there should be a setting to disable the read function response to the \r\n, but I cannot find any. For that matter, Can someone please guide to documentation that details this type of functionality using the VISA functions? I have searched the help and it gives a very very superficial explanation. I have found the VISA manual, but it only details C code implementation.
Attached is a VI that flows as explained.
Thanks

Send XML and receive binary data via SOAP
Hi folks,
following idea (Client-Server-Rendering-Architecture):
1. Send XML as JavaScript variable via SOAP to the InDesign Server
2. Attached the XML String to a new document or template
3. Apply several XMLRules to the docuument
4. Render to document as JPG|PDF whatever
5. Transmit the JPG (means binary) via SOAP back to the client
Following problems raised by implementing this
1. Build a new XML-Object with new XML() works, but how to attach this object to the document, i've just found importXML() but from file, not string and xmlElements.add() for adding just a tag not a whole xml tree. The importXML() performance from a File object is not that fast ...
2. How to render a document not to a file with exportFile() but into a variable, object etc.?
3. How to send a binary object (from an object, a variable or File object if not possible as describe in Q#2) back to the client via SOAP (scriptResult)? Do I have to expand the WSDL (and|or C++ API), any examples?
Thanks for your help, by the way, the describe scenario is what I expect of a rendering server not more not less ...
Tinofor one thing, don't use == to compare strings... You have that all over the place, like:
if(currentElement=="region") { -
Received email wants to run attachment automatically?
When I turned on my computer, the following email wanted to run automatically:
"This message is used to carry data between the BlackBerry handheld and an associated server. Please do not delete, move or respond to this message - it will be processed by the server.
BEGINETP 9
BQIAAAAAAAAA
ENDETP 145900082"
Before I run it I need to verify it is indeed from Blackberry. The sender is: [email protected]
Can anyone tell me if this is valid or bad? I have had this phone for 9 days and it is my first cell phone. Thank you.

Go to Solution.Sounds like you have Desktop Manager configured on your pc incorrectly. I believe it's configured with enterprise server have to change to internet server.

Need to create a function to receive binary files from Java WebDynpro
Hey,
I need to recieve files from java Webdynpro and save them as a file on the backend
system. After that, the file will be loaded to the documentum.
In a function module, I only can get the files as a String. Therefore (I think), I need the
binary file as base64 encoded. Otherwise I can´t get it as a string.
Now I need to decode it in the backend, but how? I know, there are HTTP-classes
in newer system, but not in the 4.6C System, I have here.
Any idea, how I can recieve the files in the function module and transfer it as binary
file to the backend system?
If I load a file from the gui with gui_upload, I get the binary file as an internal table
and can transfer it to the backend filesystem now. Maybe I can get the binary file
in this way in the function?
Thank You for Your help!

How to convert binary string to ascii
Hi,
See i have a string like this,
String str = "10011100110001011001110011000101";
Now i want to find exact ascii value of the binary string.
Thanks in advance.First want to convert these bits to corresponding
characters and then have to find ascii of the same.... corresponding to what? I think converting these "bits" to the corresponding chars is the whole story. But what about the original format?
Guessing mode on ... does this help?
String input = "...";
StringBuffer result = new StringBuffer();
for (int i = 0;i < input.length();i += 8) {
result.append((char) Integer.parseInt(input.substring(i, i + 8), 2));
System.out.println(result); -

Receiver email encoding problem using mail package
Hi to all.
I'm facing a email problem. My company email server is workig fine with emails subject but customers email server is making some strange changes when i use special characters such as 'á' or spanish letter 'n with a tail on the top'.
I set the field 'Content_Type' of the email to 'text/plain; charset=ISO-8859-1' but isn't working. If i remove those special chars, the subject is OK.
I also tried to add content conversion in the receiver email adapter in module tab but with no possitive results.
I'm using SAP PI 7.0 sp14.
Any idea of what is happening?
Kind regards,
Inigo.If you want to use non-ascii characters in email subject, then you have to apply a special notation for this, like follows:
=?utf-8?Q?Auftragsbest=C3=A4tigung?=
This is email standard. So I recommend not use non-ascii characters in email subject.
Regards

IDoc to File - Russian Characters not in UTF-8 format - File Receiver
Hello,
My scenario is Idoc to File. My SAP sender system is a Unicode system and my RFC connection to XI is also set to a unicode connection. My idoc is sent to XI OK and whenever I look at the payload in SXMB_MONI, I see the Russian characters OK, but the problem is when the file gets created.
My receiver system wants the file in UTF-8 format. When the file gets created, the Russian characters are not in UTF-8 encoding format. For example, the Russian chars look like (but without the spaces inbetween): Ð # Ð µ Ñ # Ð ¶ Ð ° Ñ # Ð µ Ð » Ñ ...
Instead, the chars should look like: Держатель
My file type in my file receiver comm channel is binary and I am also using the AF_Modules/XMLAnonymizerBean with anonymizer.encoding of utf-8.
Can someone please help me determine the problem?
Thank you,
RhondaHi Rhonda,
Hope you have set the following for your file receiver adapter :
1. Transfer Mode is set to Binary,
2. File Type Text,
3. Encoding ISO-8859-1( for Western European Latin ).
Inorder to recognize russian Character, try as follows :
Your sender idoc after coming into Pi has XML encoding declaration 'UTF-8'.
Write a simple XSLT mapping to change the value of the attribute "encoding" to "ISO-8859-1" in the output XML of message mapping . Include this XSLT map as the second mapping step in your interface mapping.
First step in your interface mapping will be your already existing message mapping.
An example of the XSL code :
<?xml version='1.0'?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method='xml' encoding='ISO-8859-1' />
<xsl:template match="/">
<xsl:copy-of select="*" />
</xsl:template>
</xsl:stylesheet>
Iam not sure whether Russian language encoding has ISO-8859-2 (Eastern European Latin) or
ISO-8859-1( for Western European Latin )...pls check out !
or you can also do java mapping instead of above mentioned xslt mapping if you are comfortable with java code !
Cheers,

Hi! I want to know if it is possible to convert the file UDPSender.java into a method that can be called by clicking a button? I slightly modified the UDPReceiver.java for it to be listening indefinitely and UDPSender.java I found on the net. And I created a what is supposedly my main file called Button.java.
What I want to do is that for this Button.java which only has a button when clicked is supposed to do a UDPSender. But I have no idea how to do it. Hope someone can answer this.

hi
i write in labview to binary file the data is double i suppose the default mode is without any headers i have succed to read it back in labview
the problem is that i cant read the file from other places
in matlab i recieve garbage
fid = fopen(filename,'bin')
data = fread(fid,....)
fclose(fid)The binary data that LabVIEW writes is going to be readable only by
LabVIEW because there is no "standard" binary file format. Each
application that can handle binary files has it's own method of
creating the file format.
If you want the data to be available to read in other applications, you
should save it as an ASCII (text) file. Most applications can read an
ASCII file is some standard format like comma separated values or tab
delimited files.
If writing speed is an issue, try first writting the files as binary, then convert them to ASCII when needed.
