How to output binary data to VISA

i am interfacing labview with pic microcontroller through serial port using VISA. it is a stream of digital data which is being tranmitted ,stored in microcontroller and then retransmiited by microcontroller to other device...problem is when that data is converted to string to be given to VISA it makes 16bytes out of 16bits...for example if data was "11110000" (1byte) after converted to string it becomes 8 bytes and my microcontroller thibk that 8 bytes are coming................ please kindly tell me how to transmit binary data over serial port so that bit remains a bit dont become byte............................ data is 99bytes but after passing through VISA it become "99x16"bytes........ please help me

The attached example in 8.0 converts a U16 into two U8, builds an array and with the Byte Array to String, converts to the hex string 8000 (two bytes). Note that the string indicator is configured for Hex Display (right click option).
Now, when you say you want to see '1000001 on the hyperterminal of other PC', you are contradicting yourself. Hyperterminal cannot be set for binary display so if you want to see '10000001' in Hyperterminal, then you need 8 bytes (one for each ASCII character).
I hope I have made myself clear.

You don't need to convert the data.
Only you can do is print it in that formats, like it:
public static String byteArrayToHex(byte[] b) {
 StringBuffer sb = new StringBuffer();
 for (int i = 0; i < b.length; i++)
 sb.append(Integer.toHexString(b&255) + " ");
return sb.toString();

How to append binary data to existing file in OSB

Hi,
I have an OSB project that I need for it to append binary data via ftp. Here's my current flow:
MFL binary output --> Replace $body with mfl binary output --> Publish to action (Business service that's configured to ftp binary data).
However, when the data is ftp'ed the following error is thrown:

From what I understand the error code 553 represents a bad file name. The file name that I'm supplying is 11802_insert_oh_xfrmr.eai_data but it appears that the name is changed to 11802_insert_oh_xfrmr.eai_data.a . So I did the obvious and changed the file several different ways (without the .eai_data extension, removed the numbers from the file name) but still no luck.
Any suggestions?

Thanks Eric.
I'm using the JCA FTP adapter instead and noticed it's appending the test generated data supplied by the OSB test console.
However, how can I ensure that the MFL output that I need to append will be placed on a new line?
Also, how should I map/assign the MFL binary output to the opaqueElement type base64Binary defined in the WSDL file below?
Once again here's a sample payload that I need to ensure will be presented on a new line:

How to extract binary data from a File?

Hello there!
Hope I'm right here.
I have a slight problem with a file containing text- and binary-data. At the beginning of the file is only some text followed by some html-code and at the end is some binary stuff like a pdf oder an image (jpg/gif).
My problem is now how to split these parts and save them in the suitable format. The text and the html are no problem, but I don't know how to extract the binary data. I tried it out with an Inputstream, but I don't know how to find the exact position where the binary data begins.
Anyone have an idea how I can solve this?
Thanks in advance and sorry for my bad english.

I don't believe a bullet-proof solution exists.
If you know where the HTML ends, you may skip whitespace and then assume the rest is binary data. Or, if you know the first bytes of the binary data, you may locate those. With either of these solutions, though, you risk coming across a file where it doesn't work as expected, for example if the first byte of the binary data happens to match a whitespace character.

How to use Binary data in Oracle(OLE DB)?

I have the Oracle 8.1.6, I can store VARCHAR2 or CBLOB into oracle database(by DBTYPES_STR). But can NOT store binary data(DBTYPES_BYTES)such as RAW, BLOB into database. My platform is VC++,ATL,OLE DB, consumer. I try to use the Oracle tools to do that, but do not successful? Can you tell me how to store data into binary column in oracle?
Thank you

Better to trim those values after the form submission.
Once you put them into form,
user may also makes mistake by hitting space, right?
Also, by trimming all form fields after submission, you will
be sure that your DB is clean... no whitespaces on it.
Well unless someone insert data directly onto it :)

How to send binary data in the message body

How can we send binary data in the message body that is base64 encoded? below are the requirements
Mime Header.
Mime-version: 1.0
Content-Type: application/octet_stream; name=test
Content-Transfer-Encoding: Base64
Submission must be named "test.sub" (lowercase)
Submission must be base64 mime-encoded
Submission must be sent in the body of the message (not as an attachment)
Only one submission per mail message
No other comments should be put in the body of the mail message (other than the submission)
I highly appreciate your help. If you can provide few examples, that will be very helpfull.
Thanks,
Madan

Use Message.setContent to set the content, or use Message.setDataHandler with
a DataHandler constructed with a ByteArrayDataSource. If the content is not
"naturally" encoded in base64, you can enforce it by setting the Content-Transfer-Encoding
header to "base64". Any reasonable mail reader won't care what encoding you use, as
long as the decoded data is correct.

Hi yzme,
You need to convert the binary data to characters, a String, before you can properly display it. You say that System.err.println(rs.getBytes("MESSAGE").toString()); prints human unreadable stuff. Maybe you need to use another character encoding, like this
byte[] message = rs.getBytes("MESSAGE");
String s = new String(message, "UTF-8"); // or "ISO-8859-1"
It all depends on how the original email message, presumably text, was stored in the database. There's no general way to convert a byte[] to a String and vice versa.
BTW, if you populate your OutMailBean using outMailBean.setMessages(request.getParameterValues("message")); then you're actually saying an email can have several messages and OutMailBean contains a String[] messages attribute. Then, you call the outMailBean.setMessage method which implies an email has one message and according to you comment OutMailBean contains a byte[] message attribute. The question is of course how you convert the String[] messages attribute to the byte[] message attribute. In other words, what does util.convertStringBufferToByteArr exactly do? It doesn't even convert a StringBuffer, but a String[]. What you probably want to do is something like
//OutMailBean bean
String[] messages = bean.getMessages();
StringBuffer sb = new StringBuffer();
for (int j = 0; j < messages.length; j++) {
sb.append("message ").append(j).append("rn");
sb.append(messages[j]).append("rnrn");
bean.setMessage(sb.toString().getBytes("UTF-8"));
Kind regards,

How to represent binary data?

I have some binary data which I want to assign to a variable. How do I do this?
To clarify my scenario:
long longConstant = 1234567890L;Is there something like
byte[] byteConstant = {1011B, 1000B, 1111B, 1101B, };Thanks in advance!

Everything in memory is binary, so that clarification didn't clarify anything. Your original post suggests you want to know if you can include integer literals in your program in binary (not octal, decimal, or hexadecimal) representation. The answer to that question is no, but it's easy to translate binary to either octal or hexadecimal by combining groups of 3 or 4 bits.
A hexadecimal literal starts with "0x":int abc = 0x22ab;and an octal literal just starts with "0" (zero, not oh):int def = 0777;

How to return binary data from a servlet?

This is my problem:
I have a table (generated from a database), and I would like the user to be able to select a one of the items in the table. When the user clicks the link I would like to transfer a piece of binary data stored in my database.
I am quite new to Creator and web apps, so I don't really know the best solution to implement this. I have one requirement: I must log the file transfer in the database (the web-servers log is not good enough...)
Any help would really be appreciated...

How to handling Binary data and File operation?

Hello Everyone,
I think this question might have been asked a lot of time but I was unable to find one solution so, please help needed in this from all you guys..
I am creating a byte[] of the media files of mp4, and jpg, using the below code,,
File ff = new File(filename);
 fos = new FileOutputStream(ff);
 int b;
 byte[] f = this.getMediaFile();
 for (b = 0; b < f.length; b++) {
 if (f[b] != -1) {
 fos.write(f);
fos.flush();
fos.close();
After i convert it i have to store it in the MySql Database as BLOB object, for retrieving byte[] from the database is simple i can do that also successfully with this code.java.sq.Blob obj = (java.sql.Blob) rs.getBlob("file");
InputStream is = null;
ByteArrayOutputStream bc = null;
is = obj.getBinaryStream();
bc = new ByteArrayOutputStream();
int b;
while ((b = is.read()) != -1) {
System.out.print(b + " ");
bc.write(b);
Now the real problem is that when i want to recreate a mp4 audio or video file i am unable to do so, the file created is smaller in size and also it doesn't get played in windows default player nor VLC. I am able to get the image file of jpg format using the BufferedImage & ImageIO.writer();
How do i do for mp4 file, have no clue for that.
Pleases help out with this.
Thanks..

if (f[b] != -1) {I don't get that line. What if you try to output the data without that condition, like this:
fos = new FileOutputStream(ff);
 byte[] f = this.getMediaFile();
 for (int b = 0; b < f.length; b++) {
 fos.write(f);
fos.close();

How to write binary data to browser - File Save dialog

Hi,
problem:
i have a working webservice and i get binary data from that webservice.
my dynpro java already works and i have byte[] b which has my binary result.
what i want:
when the user clicks on the button, the action onActionGetResult() is executed and inside this method, the byteArray b exists. what can i do, to say the dynpro application that it should send the binary data direct to the browser, so that the "File Save Dialog" appears and the user can save the file to the harddisk
any ideas?

I've found the solution:
IWDWindow window = wdComponentAPI.getWindowManager().createNonModalExternalWindow(
res.getUrl(WDFileDownloadBehaviour.ALLOW_SAVE.ordinal()),
res.getResourceName());
window.show();
this worked for me

How to convert Binary Data into XML ???

I am calling the getTaskInfo method of TaskManagerService class using Web Service API.

How to store binary data in Java

BufferedInputStream bis=new BufferedInputStream(new ByteArrayInputStream((byte[])msg.getField("GEN_UNICODE_MESSAGE_1").value().toString().getBytes()));
BufferedReader br = new BufferedReader(new InputStreamReader(bis));What on earth is all this?
1. What is the type of msg.getField("GEN_UNICODE_MESSAGE_1").value()?
2. Whatever that type is, you are then converting it to a String.
3. You are then converting that to bytes.
4. You are then casting that to byte[], which it already is,
5. You are then wrapping a ByteArrayInputStream around that.
6. ... and an InputStreamReader round that ...
7. ... and a BufferedReader around that ...
8. ... and reading lines
9. ... and appending them to a StringBuilder
10. ... and converting that to a String.
Which you already at at step 2.
String incoming = msg.getField("GEN_UNICODE_MESSAGE_1").value().toString();Not sure whether that's correct given the charset issues, but if not the problem starts at step 2. In any case steps 3-10 add precisely nothing.
This is all pointless. The key question is (1). Answer that first.
2. The type of String.getButy

Output Binary data to browser as file

I know this has been covered a thousand time, but every
example I am given does not work.
I am accessing a Java WebService to get a document (in this
case PDF). This WS has no WDSL, so I am hitting it through CFHTTP.
The WS returns me a hashmap with error codes etc. One element is a
Binary string.
I have done everything imaginable and the most I can do is
get the raw text to display. Unfortunately, saving a temp file then
using CFFILE is not an option for security reasons; however, if I
try this the file is corrupted and will not open. When I use
CFHEADER I get a complaint about java.lang.String. However,
ToBinary gives me a CF error with garbage text and no real error,
and BinaryDecode always whines about input and output encodings not
matching.
This is what I use the call the service:
<CFHTTP URL="HIDDEN" METHOD="GET" RESULT="testFN"
CHARSET="ISO-8859-1"></CFHTTP>
And these are somethings I have tried:
<cfheader name="Content-Type" value="pdf">
<CFHEADER NAME="Content-Disposition" VALUE="inline;
filename=my.pdf">
<CFCONTENT TYPE="application/pdf"
VARIABLE="#BinaryDecode(testFN.Filecontent, "Base64")#">
<cfscript>
context = getPageContext();
context.setFlushOutput(false);
response = context.getResponse().getResponse();
out = response.getOutputStream();
response.setContentType("application/pdf");
response.setContentLength(arrayLen(testFN.Filecontent));
out.write(testFN.Filecontent);
out.flush();
out.close();
</cfscript>
<cfcontent type="application/pdf; charset=ISO-8859-1">
<CFSCRIPT>
writeOutput(toString(testFN.Filecontent));
</cfscript>
None work. I either get a blank page, a CF error, or plain
text. Other Java application use this same WS without issue, so any
complaints about the WS have been ignored.
I need help badly. I am not sure what else to try.

Thanks for the reply.
I have had problems using BinaryDecode. It states the input
and output are not the same not matter what I use as the
binaryencoding. I can get a pdf binary object sent to the browser
by using this:
<CFHEADER NAME="Content-Disposition" VALUE="attachment;
filename=#fileNAME#.#fileEXT#">
<CFCONTENT TYPE="*/*"
VARIABLE="#ToBinary(ToBase64(docBINARY))#">
ToBinary nor ToBase64 work on their own (I get an error about
ByteArrays), but they seem to work together. However, now I get a
12 page PDF with 1 blank page and all the other pages generate
errors in the Adobe Reader. I have confirmed that the document
comes up fine in the Java applications that do basically the same
thing, but it is like ColdFusion does not understand the data type.
Unfortunately, our DEV and UAT systems are not exposed for me
to give you access. The Web Service I am consuming will never be
available externally, which is why I am building a CF passthrough
to display the documents to public users. The internal system will
output private contracts, so there are privacy issues related to
opening it up. Our prod deployment is very strict, so I cannot even
put up public pages for testing until all involved sign off on
functionality.
Obviously, the CFDUMP exceeds the text limit, so I cannot
post it either. :(
Edit: Also, I found out that the first byte of object is a
status code. I have parsed that off (why you now see docBINARY),
but I only see this as a square and have not been able to convert
this to the number code I should be getting.
