Errors in binary data

Hi
I am getting some errors in the binary data I am reading over a serial link using the vi attached.
The vi removes the first seven characters (which are not part of the data string) then converts the binary data to an array of unsigned 16 bit integers.
There is a regular pattern to the error- every 10th number in the array has an error.
I am very confused and was wondering if anybody has experienced a similar problem.
Many thanks
Ash

Hi,
so are you saying that if you set the instrument you're talking to to return the hex data as ascii versions (i.e. the text "002D" = a 4 byte transmit, rather than 002D a 2byte transmit (or two characters) you get the correct expected data?
As we can see from the data you've included, the 00's are there in the actual original data set, which I'm guessing is why Altenbach was asking if that was the numbers you were expecting.
The start of your actual read string is (using the slash code view) \r\nbin,\00\00,v$v\16 so to get to the first element, you need to skip the first 8 characters to be left at the ,v as the first word you're dealing with. You're currently skipping to position 7 which is \00, or 44 in hex as a word.
Is the ,v definitely the first word, or is it the v$ or the \00v and if you say that the message is
bin,<first word msb><first word lsb>...<last word lsb><CR>
then you should probably do a search for "bin," and work from the offset instead. That means your first two data elements would be 00 (or 0 as a word) then the ,v
The alternative would be to assume the \r\n on the end, and stipr that off the message. Reverse the string, and then typecast. Swap the byte order in the array of U16's, and then reverse the array again. Sounds like you're not gaining anything, but if the instrument definitely transmist as you have put it, then you would be guaranteeing the integrity of the message in words (2 bytes). (When I did this on your message, I got the same as your strip method of pulling off the first 7 elements)
Would that make more sense? What is the source of the message?
Thanks

Sporadically getting error "string or binary data would be truncated" in SQL server 2008 while inserting in a Table Type object

I am facing a strange SQL exception:-
The code flow is like this:
.Net 4.0 --> Entity Framework --> SQL 2008 ( StoredProc --> Function {Exception})
In the SQL Table-Valued Function, I am selecting a column (nvarchar(50)) from an existing table and (after some filtration using inner joins and where clauses) inserting the values in a Table Type Object having a column (nvarchar(50))
This flow was working fine in SQL 2008 but now all of sudden the Insert into @TableType is throwing  "string or binary data would be truncated" exception.
Insert Into @ObjTableType
Select * From dbo.Table
The max length of data in the source column is 24 but even then the insert statement into nvarchar temp column is failing.
Moreover, the same issue started coming up few weeks back and I was unable to find the root cause, but back then it started working properly after few hours
(issue reported at 10 AM EST and was automatically resolved post 8 PM EST). No refresh activity was performed on the database.
This time however the issue is still coming up (even after 2 days) but is not coming up in every scenario. The data set, for which the error is thrown, is valid and every value in the function is fetched from existing tables.
Due to its sporadic nature, I am unable to recreate it now :( , but still unable to determine why it started coming up or how can i prevent such things to happen again.
It is difficult to even explain the weirdness of this bug but any help or guidance in finding the root cause will be very helpful.
I also Tried by using nvarchar(max) in the table type object but it didn't work.
Here is a code similar to the function which I am using:

I have tried by converting the columns and also validated the input data set for any white spaces or special characters.
For the same input data, it was working fine till yesterday but suddenly it started throwing the exception.

Remember, the CTE isn't executing the SQL exactly in the order you read it as a human (don't get too picky about that statement, it's at least partly true enough to say it's partly true), nor are the line numbers or error messages easy to read: a mismatch
in any of the joins along the way leading up to your insert could be the cause too. I would suggest posting the table definition/DDL for:
- PSMetadata, in particular PSRowID, but just post it all
- tblProjectSur, in particularcolumns CSymbID and TblProjSurSurID
- cSymbLookup, in particular column CSymbID
- PSRow, in particular columns SampleRowID, PID,
- PSAuser and PSUserSur, in particualr all the USERID and RowID columns
- SurCSymbs, in particular colum SIDs
Also, a diagnostic query along these lines, repeat for each of your tables, each of the columns used in joins leading up to your insert:
Select count(asurv.sid) as count all
, count(case when asurv.sid between 0 and 9999999999 then 1 else null end) as ctIsaNumber
from SurvCsymb
The sporadic nature would imply that the optimizer usually chooses one path to the data, but sometimes others, and the fact that it occurs during the insert could be irrelevant, any of the preceding joins could be the cause, not the data targeted to be inserted.

Errors and exceptions in writing large binary data on sockets!!! urgent

hi
I am trying to write large binary data in the form of byte arrays on sockets.
Data is as large as 512KB(== 524288bytes) So i store the data (actually read from a file through FileInputStream ) and then write on the socket with lines like this
DataOutputStream dos =
new DataOutputStream(new BufferedOutputStream(sock.getOutputStream()));
dos.write(b);
/* suppose b is the arrayreference in which data is stored. sometimes i write with that offset + len function*/
dos.flush();
dos.close();
sock.close();
but the program is not stable: sometimes the whole 512KB is read on other side and sometimes less usually 64KB.
The program is unthreaded.
There is another problem : one side(reading or writing) sometimes gives error :
java.net.SocketException: Software caused connection abort: socket write error
please reply and reply soon and give ur suggestions
thanks

thanksUmm how are you reading the data on the other side?
some of your code snippet might help. Your writing
code seems ok. I've written a file transfer program
in a similar fashion and have successfully testing on
different platforms (AIX, AS400, Solaris, Windows,
etc) without any problems and without needing to set
the buffer sizes with files as large as 600MB and you
said you're testing this on the loopback?
Point here is you should never need to reset any of the default TCP options to get program correctness. The options are more for optimizations and fine tuning. If indeed you need to change the options to get your program to work, then you program wont be able to scale under different load.

Synch Error: String or binary data would be truncated.

I kicked off an inital synch for WebTools 2007 (may also be an issue in 596) and I had 1 synch error for SBOPartner:
String or binary data would be truncated.
The statement has been terminated.
   at netpoint.api.data.DataFunctions.Execute(String SQL, IDataParameter[] parameters, String connectionstring)
   at netpoint.api.NPBase.MarkSynched(String SynchID)
   at NetPoint.SynchSBO.SBOObjects.SBOPartner.SBOToNetPoint(SBOQueueObject qData)
   at NetPoint.SynchSBO.SynchObjectBase.Synch()
I traced the sql log and found the problem was related to addresses. The synchid only allows 50 characters but my synchid was 51 characters (COMINF, Communication Infrastructure Corporation, S). Anyway, to fix I modified the table to allow 100 characters and reran the synch. I know an upgrade will set it back to 50 but at least it's working now.
I tried to post this to support as a bug but I couldn't figure out how (as usual) or the authorization stuff changed so I figured I would post it here so hopefully the devs will see this and update the code.
Steve

Thanks Shawn ... My version of Netpoint is 2007.0.620.0 and the synch manager is 2007.0.620.35247. I'm not sure what patch level this means I am on though.

String or binary Data would be truncated. Error detected by database DLL

Having problems generating two reports in Crystal Reports v8.5. I can run it on my machine and one on one of my Terminal Server(TermA). However when I tried to generate the same two reports on my second terminal server(TermB), it crashed and I get the following error messages: ODBC error: String or binary data would be truncated and Error detected by database DLL We have one set user ID and password to generate all of our Crystal Reports.
Steps taken:
Reinstall Crystal on TermB server and did a fresh installation of Crystal 8.5 on another workstation. Ran the reports and the result were the same (unable to generate the report) same errors messages.
Please HELP...
Thanks.

Terminal Server was not supported in CR 8.5

Hi Yatan,
This should be due to data issues. And the error message is due to data truncation issues.
Please check your payload that you are trying to insert into the SQL server table.
One or more fields might have a data that is exceeding its defined length with respect to the table definitions.
Problem with using SQL server is that while inserting, you will not be pointed towards which field or column is causing the error.
You have to take the pain of searching through the entire payload to find the problem causing ones.
Thanks,
Deepak.

Error while exporting data from sql server to excel

Hi,
I am trying to export data from sql server to excel.
The query that I used is s follows
INSERT INTO OPENROWSET( 'Microsoft.Jet.OLEDB.4.0', 'Excel 8.0;Database=C:\Folder1\abc.xls','select * from [Sheet1$A1:IV65000]')
select
column1,column2.... from Table1
I get the following error message while doing so..
String or binary data would be truncated.
The statement has been terminated.
One of the column's holds data more than 225 characters.
What is the way to correct this, i want the whole data of the colum in the excel sheet.

I haven't had great luck with the INSERT INTO OPENROWSET method. Can you try one of the many samples from one of these 3 links?

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,
Yusuf

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?

Download file problem for binary data?

Dear All,
I have wrote a jsp file to do download page. I have used a piece of code from the JDC to this. This code will prompt the download dialog box each time user clicks the download button. The code itself will set the content type for different application. The code is like below:
try
java.io.File fileobj = new java.io.File(strFolder + strFile);
response.setContentType(application.getMimeType(fileobj.getName()));
response.setHeader("Content-Disposition","attachment; filename=\""
+ strFile + "\"");
java.io.FileInputStream in = new java.io.FileInputStream(fileobj);
int ch;
while ((ch = in.read()) != -1) {
out.write(ch);
out.flush();
in.close();
} catch(Exception e)
The code can download and handle text file correctly when it is openned in the text editor or inside the IE. But when a PDF file or Image is downloaded and openned in the PDF viewer or image viewer, it is corrupted and cannot be viewed. What is the problem? Any ideas?
So, I wonder this code can handle binary data or not. It is seen like there is no different code to handle text and binary data in Java/Jsp.
Thank you very much!
Best Regards,
Rockyu Lee

Add following line to JSP files.
In JSP, keep one line of source. Make sure that there are no space and additional line feeds at the any where
in the JSP files except JSP tags.

Oracle 9.2.0.8 Binary Data Problem

Hi Folks,
need some advice from the experts here about an error I got yesterday while installing a (Java-based) Software at a customer using Oracle 9.2.0.8.
While being able to work with the database most of the time, I get an error when trying to save binary data. Unfortunately I don't have access to the DB-logs, so I hope the log I have may raise a thought or two from anybody and that may help me bring some light into the darkness I'm poking in at the moment.
<log>

</log>
I searched around and got some results about
- codepage: The DBA told me that the DB is using "cp1252", so I tried to use both ISO-8859-1 and UTF-8 (both are supported by the application)
- Session Management: Tried to raise/decrease the limits for idle/maximum connections and the DBA told me to set the parameter "SESSION_CACHED_CURSORS=0", but unfortunately this is not possible when using a connection URL "jdbc:oracle:thin:@..."
So... if anybody has an idea what to check or ask the DBA to change or almost anything, I'd kindly welcome the feedback.
Thanks,
enni

Hi Sybrand,
thank you for your clarification for the codepage!
And no, I don't think that I found a new issue, just wasn't able to find a good answer on the net and after trying to get an evaluation copy (just for the install and first tests) of Oracle 9, the support told me "No way.".
And yes, you're definitely right, it should be buried.
But we all know that there are companies out there that allow new applications tests on thier "good'old" DB. Guess that is exactly what happens here.
Maybe somebody else reads this and had similiar problems in the past, so I keep this "open" for just some more time.
Thanks,
have a good time!

Convert Binary Data to string in MsSQL

Hello,
I am running a query for MSSQL database to get some file content which is stored in Binary data format in the database.
I want to copy that file which is in the binary data format to a file in the text format.
How can I do this?

This is the expected result in the file that stores the data.

Zip binary data and save zip file to disk at bsp

Hi,
First you need to define your ext prog in SM69.
It is simple though, specify:
Command name: ZZIPBIN
OS: (your os)
System command: /yourpath/zzipbin
Extra params allowed: checked
Then you need to code this:
data: table TYPE zeu_t_btcxpm.
CALL FUNCTION 'SXPG_COMMAND_EXECUTE'
    EXPORTING
      commandname                   = 'ZZIPBIN'

Thank u very much,
     FileOutputStream opGif = new FileOutputStream(destFile, false);
I have changed above line with the following line:
     PrintWriter opGif = new PrintWriter ( new FileWriter(destFile, false));
and now this code is working very fine.
Thanks once again...

Storing binary data to a file......

Hi Friends,
I am trying to make a webapp in which users can upload Videos and I can store that videos on the server. I have this bit of code:
    public ActionForward execute(
            ActionMapping mapping,
            ActionForm form,
            HttpServletRequest request,
            HttpServletResponse response) throws Exception{
                    VideoUploadForm myForm = (VideoUploadForm)form;
                    // Process the FormFile
                    FormFile myFile = myForm.getTheFile();
                    byte[] fileData    = myFile.getFileData();
}My question is, should i store the byte array into some text file???Then how can i read it back and get the original format i.e *.avi or *.mpg.
This might be easy,but this is my first time dealing with binary data,so your help would be appreciated.
Thanks
P.S: Any links would be appreciated
