Reading the data from network card

Hi,
java.net defines the class NetworkInterface. Currently there are two network cards, one is wireless and another is for LAN.I am able to retrive their names and IP addresses using NetworkInterface methods.How to read the data from a specifc network card? Can we read all TCP packets which are passed through network card?
using socket?

You cannot use (pure) Java to access the raw network data.

Can I use LabVIEW to load data directly into system memory? The serial card I'm using isn't supported by NI nor does VISA recognize it. I'm using a Win32 function to read the data from the card and now I want it to go directly to system memory.

Can I use LabVIEW to load data directly into system memory from a VI? The serial card I'm using isn't supported by NI nor does VISA recognize it. I'm using a Call Library function to read the data from the card and now I want it to go directly to system memory.
The data is being received at 1Mbps.
Thanks

Two questions:
One, if it's a serial card, then presumably it gives you more serial ports, like COM3, COM4, etc. If so, VISA would see the COM ports, and not the card directly. The drivers for the card should make it so that you see the extra serial ports from the OS. If you don't see the extra COM ports from VISA, then it sounds like the drivers for the card are not installed properly. Do the extra COM ports show up in Device Manager?
Two, you said that you're using a Call Library function to get the data and you want to put it into system memory. Errr.... you just read the data and you have it in memory by definition. Are you saying you need a way to parse the data so it shows up on a graph or something?

I have a VI and an attched .txt data file. Now I want to read the data from the .txt file and display it as an array in the front panel. But the result is not right. Any help?

The problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
Here are some of your choices to fix your problem.
1. Change the source file to a tab delimited file. Your VI will then run as is.
2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does.

Reading the data from one component view into another component view

Hi All,
I have requirement to read the data from one component into another component while creating the service order. Here are the details.
Main View for Service order: BT116H_SRVO in that we have two assignment blocks like Organizational data(BTORGSET) and amount allocation(BTAMNTALL).This two blocks are two different component which are associated with main component(BT116H_SRVO).
I need to read the sales org data from component/View(BTORGSET/Orgsetdata) into Component/View(BTAMNTALL(HdrBillPlanDet) method DO_VALIDATE_INPUT.
I searched in SDN but all the posts are related to the data exchange between two views in same component. But My scenario is different as explained above.
Refer the attachments for the component link..
Please let me know how we can achieve this one..
Thanks,
Sapsar.

Finally I was able to fix my code...My Mistakes were need to read the parent node above three levels and need to use the relation entity name while reading the data..
Below is the correction code
IF iv_index IS NOT INITIAL.
     lr_iterator ?= collection_wrapper->get_iterator( ).
     lr_current ?= lr_iterator->get_by_index( iv_index ).
     lr_entity ?= lr_iterator->get_by_index( iv_index ).
   ELSE.
     lr_current = collection_wrapper->get_current( ).
   ENDIF.
*loop back to root entity
         WHILE lr_entity->get_name( ) NE 'BTAdminH'.
           lr_entity = lr_entity->get_parent( ).
         ENDWHILE.
*Get the related entity
         IF lr_entity IS BOUND.
           lr_collection ?= lr_entity->get_related_entities( iv_relation_name = 'BTHeaderOrgmanSet' ) .
           IF lr_collection IS BOUND.
             lr_orgset_m = lr_collection->get_current( ).
*            lr_orgset = lr_orgset_m->get_related_entity( iv_relation_name = 'BTOrgSet' ).

Hi Narendra,
Please see the below code I have written
OPEN DATASET pa_sfile for INPUT in text mode ENCODING DEFAULT MESSAGE wf_mess.
CHECK sy-subrc = 0.
DO.
READ DATASET pa_sfile INTO wf_string.
IF sy-subrc <> 0.
EXIT.
else.
split wf_string at wl_# into wf_field1 wf_field2 wa_upload-field3
wa_upload-field4 wa_upload-field5 wa_upload-field6 wa_upload-field7 wa_upload-field8
wa_upload-field9 wa_upload-field10 wa_upload-field11 wa_upload-field12 wa_upload-field13

wa_upload-field34 wa_upload-field35 wa_upload-field36 .
wa_upload-field1 = wf_field1.
wa_upload-field2 = wf_field2.
append wa_upload to int_upload.
clear wa_upload.
ENDIF.
ENDDO.
CLOSE DATASET pa_sfile.
Please note Iam using ECC5.0 and it is not allowing me to declare wl_# as x as in your code.
Also if Iam using text mode I should use extension encoding etc.( Where as not in your case).
Please suggest me any other way.
Thanks for your help,

Reading the data from dataset

Hi all,
Can i read the Data from more than one Dataset at a time ?
If yes.. How ? If not...Why ?
Thanks in Advance
Krish...

You can open up to 100 datasets at the same time for every internal session.
For stability, put a TRY...CATCH...ENDTRY on these exceptions:
CX_SY_FILE_OPEN
CX_SY_TOO_MANY_FILES
...like this:
TRY.
OPEN DATASET sapfile FOR INPUT IN TEXT MODE ENCODING DEFAULT.
[your code]
CATCH: cx_sy_file_open,
cx_sy_too_many_files.
ENDCATCH.
CLOSE DATASET sapfile.
Hope this helps.

Reading the data from web

Hi guys ,
I am new to j2me ,i am going to start a project named onlineNews
for this project i need to read the data from web.can anyone help me with a sample code for reading a data from web
thank u for spending your precious time

that depends on the used technology on top of the web. I believe with J2ME you have access to the URLConnection class, so you can send HTTP requests manually. Otherwise you will need to use low level sockets, or use webservices such as SOAP or XML-RPC.
There is a lightweight XML-RPC client available for J2ME. It is no longer in development, but that doesn't mean that it doesn't work.

Populate a table reading the data from a TXT file

how can I populate a table reading the data from a TXT file?
thanks

Hey Kevin!
Using FORMS.TEXT_IO to bulk load data from a file strikes me as re-inventing the wheel. It is just about justifiable in a self-service environment, but I regard the EXTERNAL TABLE is a better solution for that situation as well.
The same applies to UTL_FILE. I think the ability to read text with UTL_FILE is primarily intended for read file-based configuration or file manipulation/processing rather than data loading.
Re-writing a text file into SQL statements is too much like hard work (even with an editor that supports macro definition and regular expressions) for no real benefit. You lose all the bulk load peformance you would get from SQL*Loader. But for QAD I'd probably let you off with it.
You missed out one obvious alternative: using Java to turn the contents of an XML file into a CLOB and inserting it into a table which is read by a PL/SQL procedure that parses the XML records and insert the retrieved data into a table.
Stay lucky, APC
