Importing very special binary data into Diadem

In order to use DIAdem I need to import binary data from transient recorders. The data is stored in block mode (CH after CH), as X-Y data pairs. All channels have different length but the structure and channel names are written into a special header block, preceeding the data. The X-Y data pairs are written into words (32-bit) with variable X/Y separation, that is that Y maybe e.g. 12-bit wide and thus X using the remaining 20 bits of the word. The X/Y separation position is coded in the header too.
Can I define a very complex import rule directly in DIAdem or can I call a LabVIEW file read and decode driver? Or is it simply impossible, except I convert all of my 120000 data sets and have them using 4 times more space?
Many thanks in advance to the experts!

Mr Mailand,
generally, you can import binary data with the function "Import via header" which you find in the file menu (submenu DAT files) in the Navigator / Data Window. Within the dialog you can specify how your data is ordered in the file. But you are limited to some standard storage mode so you might not succeed importing the data in that way.
Of course you can also call LabVIEW VIs and write the imported Data directly to DIAdem channels. The LabVIEW-DIAdem Connectivity VIs provide the functions you need for the data exchange.
Another way would be to import the data with help of a VBScript.
But there is also another method to expand the DIAdem features: With the GPI toolkit you can generate your own plugin DLLs for DIAdem. You can implement all the code you need
to import the data in a c-program and import that function into DIAdem. In that way you will be able to load your data just as any other datatype using the standard file open nemu.

Importing data in obscure binary format into diadem

Hi all,
Lets assume that I have some data in a binary format which DIAdem can not automatically import into the data portal. One method I am aware of and used is to create a dataplugin in vbs which will then allow me to import this data. Recently I came across something called the "TDM header writer" which gives me the impression that it is capable of creating a header file for my binary data and as a result will be able to import this data into DIAdem without creating a dataplugin. Is this actually the case? If the answer is yes which method is actually easiest to use dataplugin or TDM header writer?
Thanks for reading and your assistance in advance.
Matthew

Hi,
your impression is correct. With the TDM Header Writer you can write a TDM header file for your binary data, so it can be imported in DIAdem as TDM file.
However, you will need to create a TDM Header for each of your binary files. There are several ways to use the TDM Header Writer:
- C API
- JAVA API
- LabVIEW VIs
But please let me ask, if you are not satisfied with the DataPlugin you created. It should enable you to read all of your binary files without any extra work. You can export DataPlugins and distribute them. So once created, it should feel like a native file format for DIAdem.
For an overview of DataPlugins provided by National Instruments, please have a look here:

How do i import labview binary file into diadem

hi,
i am acquiring an analog input, and writing the data into a binary file. how do i access the data?
can i import the file into Diadem? if so how?
thanks
jithendra

Hi jithendra,
Well, that IS a simple binary structure. I didn't have all the scope VIs on my computer, so I couldn't tell-- do your binary data files always have a fixed number of channels (2, perhaps)? If so, it would be absolutely trivial to create a DataPlugin for you, and I would be happy to do so. Do you save your binary data files with a consistent file extension (*.bin or something)? Then DIAdem could automatically associate that file "type" with the DataPlugin, and you could simply drag and drop your binary files into DIAdem.
Alternatively, the TDM Header Writer VIs would also be pretty easy to use to create TDM header files for your binary files-- just make sure you set the byte order property to Big-Endian, as in the examples in that AppNote.
Either approach ought to work fine,

Data interpreter for loading of DASYLAB data into DIADEM

Can NI deliver a data interpreter for loading DASYLAB data into DIADEM?

Hi zzzz,
It is my understanding that DasyLab has the ability to write DIAdem *.DAT files. This I have gathered from the fact that US customers have sent me *.DAT data files generated by their DasyLab version, in which several properties are called by their German names. So I assume the DasyLab *.DAT file output was originally written for a German audience, but the data made it over just fine. I suppose that could have been a special feature of their particular DasyLab, but check if you can output *.DAT files with yours. If not, please write back.

Writing a stored procedure to import SQL Server table data into a Oracle table

Hello,
As a new DBA I have been tasked with writing a stored procedure to import SQL Server table data into an Oracle table. I have been given many suggestions on how to do it from SQL Server but I I just need to write a stored procedure to run it from the Oracle side. Suggestions/guidance on where to start would be greatly appreciated! Thank you!
I started to write it based on what I have but I know this is not correct :/
# Here is the select statement for the data source in SQL Server...
SELECT COMPANY
,CUSTOMER
,TRANS_TYPE
,INVOICE
,TRANS_DATE
,STATUS
,TRAN_AMT
,CREDIT_AMT
,APPLD_AMT
,ADJ_AMT
,TRANS_USER1
,PROCESS_LEVEL
,DESCRIPTION
,DUE_DATE
,OUR_DATE
,OUR_TIME
,PROCESS_FLAG
,ERROR_DESCRIPTION
FROM data_source_table_name
#It loads data into the table in Oracle....
Insert into oracle_destination_table_name (
COMPANY,
CUSTOMER,
TRANS_TYPE,
INVOICE,
TRANS_DATE,
STATUS,
TRANS_AMT,
CREDIT_AMT,
APPLD_AMT,
ADJ_AMT,
TRANS_USER1,
PROCESS_LEVEL,
DESCRIPTION,
DUE_DATE,
OUR_DATE,
OUR_TIME,
PROCESS_FLAG,
ERROR_DESCRIPTION)
END;

CREATE TABLE statements would have been better as MS-SQL and Oracle don't have the same data types.
OUR_DATE, OUR_TIME will (most likely) be ONE column in Oracle.
DATABASE LINK
Personally, I'd just load the data over a database link:
insert into oracle_destination_table_name ( <column list> )
select ... <transform data here>
from data_source_table@mssql_db_link
As far as creating the database link from Oracle to MS-SQL ... that is for somebody else to answer.
(most likely you'll need to use an ODBC driver)
EXTERNAL TABLE
If the data from MS-SQL is in a CSV file, just use and external table.
same concept:
insert into oracle_destination_table_name ( <column list> )
select ... <transform data here>
from data_source_external_table

Loading Labview Binary Data into Matlab

This post explains the Labview binary data format. I couldn't find all of this information in any one place so this ought to help anyone in the future. I didn't want to add any overhead in Labview so I did all of my conversion in Matlab.
The Labview VI "Write to Binary File" writes data to a file in a linear format using Big Endian numbers of the type wired into the "Write to Binary File" VI. The array dimensions are listed before the actual array data.
fid = fopen('BinaryData.bin','r','ieee-be'); % Open the binary file
Dim1 = fread(fid,4); % Reads the first dimension
Dim2 = fread(fid,4); % Reads the second dimension
Dim3 = ...
Each dimension's length is specified by 4 bytes. Each increment of the first, second, third, and fourth byte represent 2^32, 2^16, 2^8, and 1 respectively. 0 0 2 38 equates to 2*256 + 38 = 550 values for that particular dimension.
As long as you know the number of dimensions and precision of your binary data you can load it.
Data = fread(fid,prod([Dim1 Dim2 Dim3]),'double',0,'ieee-be'); % Load double precision data
If you have appended multiple arrays to the same file in Labview you would repeat this procedure. Load each dimension then load the data, repeat.
Data = fread(fid,prod([Dim1 Dim2 Dim3]),'int8',0,'ieee-be'); % Load int8 precision data or boolean data
I had to create a function for my own purposes so I thought I'd share it with everyone else too. I uploaded it to the Matlab File Exchange. The file is named labviewload.m.
This was tested on Matlab R2007a and Labview 8.2.

Thanks. I have the same questions as I tried to load labview binary data into Matlab.

Convert Binary Data into Pdf & send it as attachment in a mail in Workflow

Hi,
Scenario:
The interactive form saved in WebDynpro Application is sent to R/3 in binary format. It has to be converted into pdf and sent it as an attachment in mail to the respective person in workflow.
Kindly help on these issues :
1. How to receive the binary data in R/3 sent by the WebDynpro Application ?
To my knowledge we can receive the binary in XSTRING data type. Plz correct me if am wrong.
2. How do i convert the received binary data into pdf ?
Thanks,
Bharath Kaushik

Hi Bharath,
I think you should try to write dat being sent to R/3 to spool first, as in R/3 there is FM CONVERT_ABAPSPOOLJOB_2_PDF , with the help of which you will be able to convert Binary data to PDF format.
Pls find one of the threads related to this , and see if this is useful to you.
Problem in CONVERT_ABAPSPOOLJOB_2_PDF.
Hope this atleast helps to start off.

How-to bind binary data into textbox

can i bind binary data into the textbox....
coz..i get human unreadable character
[B@184b867# binary data - byte array
supposingly ..i just need to convert to bytes.toString() to see the content...
yet i try but..it still return this weird character...any idea...
OutMailBean outMailBean = new OutMailBean();
outMailBean.setHost(request.getParameter("SMTP").trim());
outMailBean.setPort(request.getParameter("port").trim());
outMailBean.setMessages(request.getParameterValues("message")); //string[]
//convert to byte array
outMailBean.setMessage(util.convertStringBufferToByteArr(bean.getMessages()));
//insert into table
Statement stmt = con.createStatement();
try {
ResultSet rs = stmt.executeQuery(squery);
try {
while (rs.next()) {

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,
Sigiswald

Best way to put binary-data into string?

Hi there!
What I want to do is to transfer binary data via HTTP/GET so what I have to do is to transfer binary data into a string.
Currently I do this the follwing way:
 byte[] rawSecData = new byte[4]; //any binary datas
 ByteArrayOutputStream secBOS = new ByteArrayOutputStream(4);
 DataOutputStream secDOS = new DataOutputStream(secBOS);
 for(int i=0; i < rawSecData.length; i++)
 secDOS.writeByte(rawSecData);
secDOS.flush();
String secData = secBOS.toString();
System.err.println("Lenght of resulting String: "+secData.length());
I know that this way already worked fine, however I now set up my system up again with another linux-distro and now strange things happen.
e.g. the secData string differs in lenght from run-to-run between 2 and 4 and I don know at all why?
Transferring the binary-stuff into string-stuff (e.g. short-binary 255 255, String: 65536) is not possible for me because of various reasons.
The funny thing is that I remeber that this already worked some time ago and I can figure out why it now doesnt...
Please help!

First of all thanks a lot for your help!
Yes, I already think its an encoding problem, but how can I specify the encoding in my application in a portable way. I dont have an idea what to do.
My applikation should run as applet on many different 1.1+ VMS (msjvm, netscape-1.1.5, ...).
Thanks again, lg Clemens

Binary data into a XML

Hello,
I'd like to know how I could insert binary data into a XML message, for example, an image.
Does XML Java API support binary data insertion into a XML message? Or should I make my own classes to do this?
As I've read in the next url http://www.javaworld.com/javaworld/javatips/jw-javatip117.html ,
the best approach is to use a Base-64 encoding. The encoding algorithm processes a byte stream in 3-byte sequences. Each 3-byte sequence parcels into four 6-bit data units. Each 6-bit data unit then encodes into the character stream as the corresponding character from the character set: A-Z, a-z, 0-9, +, and /.
Thanks

Does XML Java API support binary data insertion into a
XML message? Or should I make my own classes to do
this?The XML Java API's support producing well-formed XML according to the XML specifications. Those specifications do not say (or even suggest) how you should encode binary data to put it into XML. If you want to encode your binary data in some way then you are free to do so, but you'll have to write your own code.

How do I import non-numeric data into DIAdem?

I have some non-numeric data in an Excel file which I would like to import into DIAdem. DIAdem recognizes the file and imports some of the data, but it only imports those cells that are purely numeric. Cells containing non-numeric characters are ignored. But I need that non-numeric data! How do I force DIAdem to import everything? (Some controls appear in the import dialog that seem like they might be useful here but they're greyed out.)

Hi There,
You can not load text columns from ASCII files into DIAdem 8.1 DATA channels (numbers only). But the ASCII Import Wizard will let you send those text values to either a separate ASCII file, which DIAdem can use to put them on a graph as labels, or to a DIAdem string array, which DIAdem can use to display them at various places in its environment.
The below attachments demonstrate reading an ASCII text column into a DIAdem string array and displaying the values on a DIAdem table in GRAPH. Note that the index values of the string array are placed in a DIAdem DATA channel.
Ask if you have further questions,
