Read and display data from PC COM1 & COM2

Hello, I am looking for help in order to use LabView to do the following:
I want to read from RS232 dataloguer output information and write
this in a text file format and then another LabView rutine should read
de information from the file and present the data in a graph. This
basically what my Meteorology interface is doing at the moment but I
want to use LabView for this purpose.
I've been doing some tests but unfortunatelly I haven't gone very far.
Many thanks, regards. Jose Carlos
Hola, buzco ayuda para hacer una peque~na aplicaci'on con LabView:
Necesito leer la salida del puerto RS232 de un dataloguer usando el
puerto de comunicaci'on del ordenador COM1 y escribir estos datos en
un fichero de texto. A continuaci'on otra peque~na rutina en LabView
deberia leer la informaci'on desde el citado fichero de texto y luego
presentar estos datos en una grafica.
He estado trabajando en este tema desde hace tiempo pero sin mucho
exito; espero me puedan ayudar con alguna sugerencia.
Muchas Gracias. Jose Carlos

Hi,
I send two links where you can see how to communicate with your instrument using RS-232 port and other example where the data are saved into a file after being acquired.

In order to read the data of the file you can see the example on the Labview´s help on Fundamentals>>File Input and Output
I hope this helps you

When I try to create an external content type based on a view (AdventureWorks2012.vSalesPerson) - I can display the data in an external list. When I attempt to edit it, I get an error:
External List fails when attached to a SQL view
Sorry, something went wrong
Failed to update a list item for this external list based on the Entity (External Content Type) 'SalesForce' in EntityNamespace 'http://xxxxxxxx'. Details: The query against the database caused an error.
I can edit the view in SQL Manager, so it seems strange that it fails.
Any advice would be greatly GREATLY appreciated.

Read and Get Data from PDF

Hi All,
I am fairly new to programming macros in Excel VBA, and right now I need to write a macro that can open a PDF file and read it and get data from there and paste it into an excel spread sheet. Is this possible? If so can you give me some sample code
that would do that?

I did this once many years ago. I had to have Acrobat Professional installed ($$$). There are free pdf parsers that you access from VBA using Win32 commands like:
https://code.google.com/p/peepdf/
Maybe something has changed since I did it

Read and write data from content repository .

Hi All,
We are using content repository to store some document and images on web center server .
So we have created/setup a content repository on web center .
Please proivde me some documnet /wiki page to get some idea how can i read and write date in
content repository .
You are most welocme to provide some idea /suggestion .
Thanks,
Arun.

Have you already configured webcenter spaces so it can use content server?
Have you installed the content server seperatly from webcenter or as a part of the webcenter installation?
Check if you have the webcenter spaces component installed in content server because without i don't think it will work...
If you already have configured UCM to work with spaces it's quiet easy.
From your groupspace, open the settings page of your groupspace. Go to the services tab. In the left hand side you can enable the documents services. WHen you have done that, you are able to add the document services taskflows to your pages. Just go to a page in your pagegroup and edit it. Open the resource catalog and you will find some extra taskflows you can add.
If you haven't configured UCM and webcenter to work together, here some steps that will help you:
* Integrating UCM with Spaces
     * They both need to use the same LDAP store.
     * Since there is no LDAP server available, we choose for embedded WLS LDAP.
     * Integrating the ucm into apache
          * Stop UCM
          * In /oracle/product/wls10320/WebCenter/ucm/config/config.cfg, check the SocketHostAddressSecurityFilter to contain 127.0.0.1
          * Add the SocketHostAddressSecurityFilter to /oracle/product/wls10320/WebCenter/ucm/admin/bin/intradoc.cfg
          * Add to /oracle/product/wls10320/WebTier/instances/instance1/config/OHS/ohs1/httpd.conf
               include /oracle/product/wls10320/WebCenter/ucm/data/users/apache22/apache.conf
          * Change the mod_wl_ohs.conf file to
               <IfModule weblogic_module>

How to acquire and display data from labview to excel simultaneously

hello,
I am using the NI-DAQ to measure the falling edges of a clock and display them into a table. What I need is to display these data in a table in excel while the program is running. In addition, when I receive a pulse from an external clock, for which I have created a digital channell, the data must be logged in a different column. In other words, every time I receive a pulse the data must be stored in the adjacent column in excel.

Hello Evangelos,
As far as I know and have experienced, it is not possible to access a spreadsheet file (or any file, for that matter) by two programs at the same time, you will get an error.
Also, a couple of observations on your code:
A constant wired to a case selector of a case structure makes no sense as the false case will never be executed.
Move the DAQmx Read from your Digital Input task into the while loop, as the DAQmx Read will only read once and the wire won’t get information in or out of a while loop as long as the while loop is iterating.

Read and write data from / to cube in CUSTOM_LOGIC BADI

Here are the details:
BPC displays a set of details - with 5 rows and 5 columns. There are 50 additional rows for the 5 columns which are blank to start with.
User changes a cell. BPC 10 only sends that cell which is changed by the user in CUSTOM_LOGIC and WRITE_BACK BADIs.
I need to get other 5 X 5 cells (other than 1 cell, which is changed and being passed in the BADIs) details to determine all the details and calculate the additional 50 rows. After calculating these values, i need to update the cube so that the BPC report refreshes with the data i have updated.
Whats the best way? What are the funtion modules involved in reading / writing? Are there any best practices to read / write data from cube.
Appreciate your help.

Hi Ravan,
Look at my sample write back badi here: http://scn.sap.com/message/14290977#14290977
At the end of the code I have values updated in ct_data. The contents of ct_data will be automatically written to the cube (you don't need to have special code to write data).

How can I read and display data with OR without recording at the same time?

Hi all,
This forum has been of much help to me, but I have a rather specific question I can't seem to find an answer to. I am new to LabView, educating myself with tutorials, trial and error, and this forum.
Attached is what I have so far. I would like to read data (three voltages) and write it to an excel file. As written below, it will do nothing until I click the "Record" button, when it then takes data, displays it on the gauges and waveform chart, and writes it to a file. What I would like it to do is display the data at all times, and record when I click the record button (while still displaying data being read). I have tried to do this by moving the DAQ Assistant VI, gauges, and waveform graph outside of the loops, but when I do this, it will read until I press record, and then it simply records whatever value it's stuck on. Sorry for the long post, thanks for any help.

Record and Write to File 2.vi ‏332 KB

Sorry, I don't have any DAQ installed, so I won't comment on the DAQ parts.
First of all, Your VI will do nothing until you (1) first set the record button to ON and (2) press the start button in the tool bar. It almost seems that you are using the "continuous run" button. (Don't! That's not its purpose. Basically, it automatically restarts the program whenever it finishes). A toplevel VI should never stop during normal operation, so place a big while loop around all code and create a wait state that does nothing until you tell it to acquire.
You don't need the inner while loop, simply place your code inside the big while loop (and accumulate your array data in an initialized shift register if really needed. Currently you do at the inner loop boundary for some reason). You have a big problem that the array can grow without bounds unless you clear the accumulated data once in a while or place it in a FIFO buffer of limited size. If you let ot grow forever like you do now, the program might run out of resources at one point in the future.
Since you are appending to your file, maybe yo don't need any shift register, just use the data points of the current iteration. Place your save operations in a case structure and keep appending the new data to your file only if the case is true.
It is also very inefficient to use highlevel file IO here,because each instance opens and closes the file. I recommend to open the file once outside the loop, then use low level IO to append, and close the file once the big loop is done.

How to read and write data from json file from windows phone7 app

How can I do?
Thank you in adv and please, reply soon.

We don't have many samples left for Windows Phone 7 + Azure, the closest one to what you want to do is probably:
Using Local Storage with OData on Windows Phone To Reduce Network Bandwidth
this sample uses the local database feature: 'LINQ to SQL', available to Windows Phone 7.1 and 8.0 Silverlight applications, instead of simple file storage but even if you choose to stick with simple file storage I believe you should be able to adapt the
networking related portions of the sample to your particular application.

How to read and store data from an SQL resultset

I'm writing a program to create testing scripts. I have a working version of the program that takes data from a specific input file, processes it and then outputs it as a test file that is readable by this other system. That's all fine and dandy, but now I wish to extend my program so that it doesn't need the input file, it shoud run an SQL query on the database itself and output this, with some other data to the output file, I have been experimenting with some code below:
          ResultSet rset;
          rset = sql.sqlweight();
          while (rset.next()!= false)
               System.out.println("I'm getting to this loop");
               scanCode = rset.getString(1);
               System.out.println(scanCode);
               rset.next();
          }And method sqlweight looks like this:
     public static ResultSet sqlweight() throws SQLException
          Connection connectiona = DriverManager.getConnection(//hiding connection details);
          Statement stmtW = connectiona.createStatement();
          String sqlW = "Select distinct (selc_code) from selling_code, prod_orgu_link where selling_code.prod_id = prod_orgu_link.prod_id and prod_orgu_link.prou_prod_handling = 20";
          ResultSet rset = stmtW.executeQuery(sqlW);
          while (rset.next())
               //System.out.println(rset.getString(1));
          //rset.close();
          //stmtW.close();
          //connectiona.close();
          return rset;
     }Code is a bit messy at the moment as I am constantly changing and adding things so excuse the formatting. I can't get it to enter the loop (hence the testing line I put in it). I am wondering what the best way would be to get the data held in the results set into my String variable scanCode. Thanks for any help or advice.

I haven't thrown it away, it just looks like this now:
     public static ResultSet sqlweight() throws SQLException
          Connection connectiona = DriverManager.getConnection(//hiding connection details);
          Statement stmtW = connectiona.createStatement();
          String sqlW = "Select distinct (selc_code) from selling_code, prod_orgu_link where selling_code.prod_id = prod_orgu_link.prod_id and prod_orgu_link.prou_prod_handling = 20";
          ResultSet rset = stmtW.executeQuery(sqlW);
          return rset;
     }

How to read and write data from Excel to TestStand without using LabVIEW VIs

Hi,
How can I read in columns of data from Excel into a TestStand array and write columns of data to Excel from TestStand without using LabVIEW VIs?
I don't think the Property Loader custom step type in TestStand will work because the data I would like to read in from Excel is in a column that is thousands of rows long and the data has to be in the proper format to use the Property Loader to load in an array from Excel.
Thanks for your help.

That example does not use LabVIEW and it does about 40% of what you need to do by calling Excel through ActiveX. If you don't know how to use Excel through ActiveX then you'll need to brush up on that.

Querying and displaying data from a database

Hi,
The environment I am working in has the EBIZR12 suite installed on the apps server APP1, the EBIZR12 database deployed to server DB1 listening on port 1522 and a MIDTIER database deployed to server DB1 listening on port 1521. I have a custom page that needs to query the data off of MIDTIER and populate a display table. The page I have created emulates that of the Search tutorial. I have an application module that contains a BC4J object and views and these are connecting to the MIDTIER to retrieve data. It has a table that should display queries returned from the MIDTIER database. My question is, are there any limitations with OA framework development and deployment that would NOT make this feasible? if not is there anything else I would need to do either as a pre-requisite or as part of my page construction to make this work, because currently my page table is not being populated and I am not getting any exceptions on the page to indicate the database is either unreachable or the connection configurations are incorrect. Any help is very much appreciated.
regards,

Yes, in case of query region, an executequery was getting called on clicking go button. But now as you just have a table mapped to a VO, you also need to call the executequery explicitly in the page controller's processRequest method.
Your point "I would like to point out that the instructions in those tutorials are not compatible with the newest version of JDEV" is completely wrong. First of all each Jdev has its own set of tutorials reflecting all the changes in that particular version. Secondly, as you are trying to use a particular scenario steps to create something different, you can't expect it to handle all the side off scenarios you can make. Drag and drop UI won't get you more than a few basic screens. Read more and you will understand the working of framework.

TABLES
intern = intern
EXCEPTIONS
inconsistent_parameters = 1

OTHERS = 3.
After getting Records in INTERN TABLE You can loop it to check where columns B & C are empty and store them in another table .
LOOP AT intern.
IF INTERN B and C has value .
CONTINUE
ELSE .
MOVE THEM INTO ANOTHER TABLE ITAB .
ENDIF .
ENDLOOP.
THEN LOOP ITAB .
WRITE : ' '
ENDLOP .
Hope this Helps .

"I want to acquire and display data from 89C51 micro controller using RS 232 port"

I am using 89c52 for data acquisition and control for photo diode array. I would like to do the same using RS-232 and micro-controller 89c52. I would like to generate two different control pulses (clock and trigger) and I am digitizing my analog data using on-board ADC, the data for which I would like to read using Labview and store it in a file also display the waveform of acquired data. Please reply.

Nice project, we do that all day long here. What is your problem exactly?
The 89C52 has a UART you can use to write commands and read data. It is fairly straightforward to write a command processor for the uC and implement a command set. Is it the computer or the uC that generates the control pulses?
