Binary file with header
hi,
i want to read a binary file in Diadem, which i saved it with Labview. But i didnot get it.
Could you please help me?
my header files looks like:
1 bit double,
128 bit U8,
1 bit unsigned word,
1 bit dbl
16 bit U8
64 bit U8
1 bit u32
1 bit i32
and 100 bit Data.(i16)
Thanks.

Hi Hakan,
There were several issues with your VI, and the VI bore very little resemblance to the list of binary header items you included in your first post. I decided to follow the VI instead of the earlier binary header property list. In the VI, I changed the data type of your channel name property zero-padding from I32 to U8. I changed the byte order of your binary header to match the byte order of the bulk data (Big Endian). I also changed the file creation function to "create or replace" so that I culd run the VI multiple times and overwrite the same data file. The DBL that you are writing from the LabVIEW date/time wire is a geography-specific number of seconds since January 1st 1904 (in Greenwich England). I added a routine to the DataPlugin to decode this into a DIAdem geography-independent date/time property based on my current location in the Central time zone. You could instead save a geography-independent DBL in the VI, which would probably be a more robust approach.
I assigned all the header properties to the Channel level, though you probably want to copy them to the Group and/or the File level as well. I suspect that the 3 DBL properties have something to do with the I16 channel vertical scaling or else the time scaling (aquisition rate). We could add that to the DataPlugin as well.

I have written a binary file with a specific header format in LABVIEW 8.6 and tried to Read the same Data File, Using LABVIEW 7.1.Here i Found some difficulty.Is there any way to Read the Data File(of LABVIEW 8.6), Using LABVIEW 7.1?
I can think of two possible stumbling blocks:
What are your 8.6 options for "byte order" and "prepend array or string size"?
Overall, many file IO functions have changed with LabVIEW 8.0, so there might not be an exact 1:1 code conversion. You might need to make some modifications. For example, in 7.1, you should use "write file", the "binary file VIs" are special purpose (I16 or SGL). What is your data type?

How do I import binary data files (with header info) into DIAdem?
We have lots of data acquired by nCode datagate. Files are binary data with header info. How do I import this into DIAdem? Typical (short) file attached. Also of interest, can I stream data from Sony PC208/SIR1000 recorders?
Attachments:
Propshft.dac 4 KBI have successfully imported your file into DIAdem using the nCode file filter included with DIAdem. You might have to make that file filter known to DIAdem by following these steps (this assumes you have version 8 of DIAdem):
1. Go to the 'Window' menu in DIAdem and select 'Close all'
2. Go to the 'Settings' menu and select 'GPI-DLL Registration'
3. Click the 'Add' button in the window and select the 'GfSnCode' DLL in the 'DIAdem/AddInfo' directory
4. The program will prompt you to restart.
5. After you have restarted DIAdem, go to the DATA icon, select 'File - Open' from the DATA menu and in the dialog that appears, choose 'nSoft Data File Format' in the 'Files of type:' field.
6. Select your data file and load
That's it.
With regards to your Sony reco
rder data, I would need to get my hands on an actual data file to try it out. In general, DIAdem can import ANY binary file format by creating a header in the 'File - Import via header' section in DATA. If you have lots of data files from the SONY recorder, a DLL can be created for that specific file format with the free DLL toolkit included with DIAdem.
Leave me a message here if you have any additional questions.

Hi all,
We have requirement to send data to FTP server,
am able to send data to FTP server, but the problem is am not able to send file with Header,
Eg:
oreder numer netvalue discount Grossamount
90000909 2323.34 343.33 4545.000

90000909 2323.34 343.33 4545.000
i have to send the file in the above format.
plz guide me hoe to create file with above format?
REgards,
DS kumarHi,
Use the following code to create header.
DEFINE add_field_header.
clear &1.
&1-field = &2.
append &1.
END-OF-DEFINITION.
add_field_header heading 'oreder numer'.
add_field_header heading 'netvalue'.
add_field_header heading 'discount'.
add_field_header heading 'Grossamount'.
In GUI_DOWNLOAD pass heading to Fieldnames parameter.

Generate target/out file with header record as Record Count ?
Hi Kareem, Please try the below approach. Pipeline 1: Load actual data(without header with record count) from source to target. Let say your file name is intermediate1.dat Pipeline 2: Take the target from pipeline 1 as source and create the header with count of source file using an aggregator. The filename of target for pipeline 2 will be your final file(header and detail data). Pipeline 3: Take the target of pipeline 1 again and do 1-to-1 load to the target file of second pipeline. In session properties, dont forget to tick the check box append if exists for the third pipeline target. There may be other simple approaches also. If you have no time in hand try the above approach. Let me know if you find any issues. Thanks,Deeshan.

How to upload a binary file with Firefox 7
Don't know if this is the right forum to ask this - if not, please point me in the right direction.
I am an embedded developer using Firefox as the user interface to an embedded web server. In the past I've been using file.getAsBinary() to read the local file which is then uploaded with an XMLHttpRequest. Firefox 7 removed the getAsBinary method. Looking through the documentation I came across FileReader and have been trying to use that but with no luck. When I use the readAsBinaryString method, the binary has many bytes which are in error. I have also tried the readAsDataURL but this gives me base64 encoding. Attempts to decode it so far have been unsuccessful. What's the best way to get a local file and upload it to a remote server?
Thanks,
DaveWell, actually, i have no perfect solution.
I just used a temporary internal table in which all fields are characters. Then, I used FM GUI_UPLOAD to upload text file including header into this table as usual.
You can see that it was done successfully. Next, use a loop to transfer this temporary table to the main table. SAP will automatically convert data into values that are compatible with data type in the main table, so don't worry about different types :D.
In order to make this work more simple, field names of temporary table should be named exactly as same as those in the main one. So, u just use:
loop at itab_tmp.
move-corresponding itab_tmp to itab_main.
append itab_main.
clear itab_main.
endloop.
note: both tables have their own header line, so don't need use a working area here.
Anyone has any better solution? -

The reading of a string from a binary file stops at a NULL character (0x00). When the first character is 0x00, you are just reading the one character. I would suggest writing to a byte array since you are doing the inverting. And then you can read as a byte array.

U rocks..!!

After playing around a little more, I think I might have misinformed you a little. If you explicitly tell it a string, it looks for the string length at the very beginning and reads that length of bytes as a string. It appears that if you implicitly tell it to read a string (not wire the data type) it reads all of the bytes directly, including the length of string you wrote.
Regardless, my advice is the same. You should just write and read using byte array. It is less conversions if you are performing your "encryption".

How to handle text files with Header lines
Hi,
Eventhough the number of header lines is specified, when I do Reverse to get columns, its considering only header line.
I have file format like
ffserver started.

first line is header line and there are spaces within a field value, and the field separator also is space.
regards,
Vivekin this scenario of urs ,ur file has multiple delimiters like -- and spaces.
in this case u need to convert the file in a file with single delimiter .
this can be done by writing a code in java in ODI procedures.
once you have the same delimiter all over the file.
u can extract multiple headers using typical Procedure -

Hi gurus,
I am getting binary file as base64binary (not a text/xml file) in a request XML tag. I need to write this file to a file directory with the file adapter after retrieving it from the request message by a message/java mapping and use another field in XML as the file name.
I followed the blog `how to send binary data through PI` but in that case, the request message is also the same. Mine requires a mapping to be executed and in this case I cannot use dummy names for message types/interfaces as Enterprise Repository development is required.
How can I achieve this?
Thanks
GokhanJust solved the problem actually
As I was trying to write a binary file directly with the receiver file adapter, I wasn't sure how to define a data type / message type for it. I developed a java mapping that decodes the base64 to binary data and writes it to the output stream, and used a dummy message type / data type for the service interface as the target in Operation Mapping
And it worked!

How to get rid of a binary file with firefox that pop up allthe time?
each time that i open moxilla firefox a box asking if I want to save or cancel the binary file. I have tried to ignore ti however it has become a bother. How do I stop the box from popping up ?
Hi
if you mean http://db.tidbits.com/ - I didn't get any popups in a few minutes of browsing there, this without any blocking software. If you're seeing the very same ad popup window from differing sites, then it'd sure be worth looking at whether or not your mac or router or isp is using some rogue dns server.
DNS - Domain Name System
it translates domain names meaningful to humans into the numerical (binary) identifiers associated with networking equipment for the purpose of locating and addressing these devices worldwide. An often-used analogy to explain the Domain Name System is that it serves as the "phone book" for the Internet by translating human-friendly computer hostnames into IP addresses. For example, www.example.com translates to 192.0.32.10.
to borrow from wiki.
DNS servers can be chosen in your router or in your mac at System Preferences-Network-Advanced-DNS tab, If no special dns servers are selected, your router will usually accept the isp's suggestion, so you'll be using theirs, for better or for worse.
The most common place for any 'rogue' dns to be set, is in System Preferences-Network-Advanced-DNS tab... look there on your mac, and see if any numbers are visible. Copy them & paste here, then we'll know what's going on. -

Upload binary files with Developer Forms
Hi all,
I'm newbie with Forms and I don't know if this question is already answered.
I'm deploying an application involved with blob columns (binary files: pdf, doc, gif, etc) I want to let users to choose files from his PCs (typical "Browse files" button) but I don´t know if this is possible and if yes, how to implement it.
Anybody can help me?
My email is [email protected]
Thanks in advance!
CristinaIf you want to upload direct into the database from the client then No you will need a 9i database or above.
If you want to upload a file from the browser client to the middle tier (Application server) then that will be OK no matter what DB version you are using. Bug of course you'll then need to do the last bit yourself if you want the document / image put into the database. -
Opening a binary file with the right extension
Hi everyone,
I developed a real simple VI that enables me to read the first five bytes of a binary file to get its signature (ASCII) and verify if its signature matches with the expected extensions. If yes, another VI is called, and if not a 2 button message error is displayed : if the User chooses OK, then a new dialog box opens up to pick another file ; and if the user chooses Cancel, the same dialog box opens up rather than escaping the VI.
It is due to the while loop (VI below) but i don't see how I can handle this without it. Till the user hasn't chosen the right extension, it can't escape which is a problem! The true case consists in calling another VI, and the first step of the stacked sequence consists in displaying a two button error message.
If you have any ideas, I'm a bit new! Thanks !!
Solved!
Go to Solution.Thanks for your replies!
I have tried your solution CoqRouge, filtering the extensions. But it seems that you can choose between different filters when the dialog box opens up, and then choose any kind of extensions.
