• How to create a matrix with variables

  I have 12 double variables (and not a table) and I wanted to put them all in a 4 x 3 matrix. I tried to use the matrix to build, but I didn't know how I would define which variable would be in every position of the matrix.

  Hi humberto,

  I thought that this would be explained in the tutorials beginning for LabVIEW, offered free of charge on the website of OR:

  

  Pretty easy, huh!

  Please go through these tutorials. Study the screws coming with LabVIEW example.

• recorder with variable unit

  Hallo!

  I tried to use the recorder with variable units. It does not it? Can I change the units of the recorder of the version of the runtime somehow?

  Thanks for your advice.

  Hello again!

  I found the solution:

  Even when it is not possible to use a variable in the context menu, it is possible to put a global string in the recorder manually. I put "${Unit_Ch1}" on the ground for the unit, and it worked.

  Have a good day everyone.

• Insert text in a matrix with numberic values

  I have a matrix that I write numberic decimal values but I would like to know if there is a way I can also write text in the same matrix. Currently, I have a 10 x 6 Matrix which contains numberic values (data), but I would add a text column to the matrix. I use the matrix to display data.

  If reaaly you need a data type of matrix for mathematics you will make, it could make more sense to have an array of distinct strings for the headers of lines.  I used the classic Simple string for the elements of the array. Of course your reveal hide the label as string array and display the Index.

  

  Also, simply create an array of numeric values by autoindexing 2D and then use the table for primitive matrix outside the loop.  It will be much more effective than the use of Insert in the table and a local variable.

• Using DAQ Assistant with a system remotely

  I'm new to LabVIEW and National Instruments hardware and I am trying to use an instrument with LabVIEW using the DAQ Assistant. I use a PC with Windows Vista and I am connected via a network to a PXI-8108 controller in a PXI-1050 chasiss chassis. The instrument is just a thermocouple which I use to become familiar with everything. The thermocouple is connected and the connection SCB-68 block which is connected to a PXI-6221 multifunction data acquisition in the chassis. I am able to create a task in MAX under remote system and everything seems to work. What I want to do is to use this instrument in LabVIEW, and it seems that for this I need to use the DAQ Assistant, but when I do it says no supported device is found. I wonder if there is a way to get LabVIEW lean on the remote system to see the acquisition of data and the thermocouple.

  All advice is appreciated.

  Thank you

  Hi all

  Ben is correct.  RDA is no longer supported in DAQmx.  We have another way to use DAQmx with a remote system.  It is use DAQmx with an OPC server or simply by shared network variables.  There is a section of the base of knowledge here that should help you get started.  You should also take a look at the developer section area here.  The basic idea is that you can use a variable shared within labVIEW that is bound to a variable shared on your networked machine.  In this way, you can write and read values from a task DAQmx.  Look at the instructions in the above two items and let me know if you have any questions.

  Kind regards

• Problem with variables not excluding search terms not

  People,

  I'm having a problem with variables, when used in topic titles.

  We produce two distinct versions of a webhelp. The text is almost exactly the same, but the product has a different name in each version. In one version, he is called FLOW; in another, it is called Service generator. We use the user-defined variables to control which name is used to identify the product, when we generate the webhelp.

  So, I have (for example), a subject that begins with the heading:

  Construction of a FLOW script

  where the text occupied by 'FLOW' is provided by a variable with two values - FLOW and Service constructor.

  So when I generate the generator using the web Service version, I put Robohelp using the Service Builder variable defined, and all contained text and the table of positions generate fine; FLOW is nowhere to be seen.

  But when I type "FLOW" in the search box, the system identifies each of the three subjects that are built as in the example above, with a topic title that contains the variable used to set the name of the product. In addition, it displays in the search results using STREAM in the title of the topic, not Service Builder (but when I open the topic, the text in the header is rendered correctly).

  In addition, the system uses the "FLOW" and not "Service Builder" in the headings found by the search, regardless of what research the term is used.

  Everyone comes through this? Nobody knows how to solve this problem, please?

  Thanks in advance,

  NA.

  What version of RoboHelp do you use?

  I use the 2015 Release version. It used to be version 11.

  In the Release version of 2015, my topic Properties dialog box looks like this:

  

  I think that version 11 may have introduced the possibility of having a variable in the title of the topic. If your version is older and does not seem to offer a way through the dialogue box to deal with this, I was wondering if you could fudge by manipulating the code manually. For example, I see that when I use a variable in a topic title, I end up with this:

  

  So I was wondering if you could add just in the bit that reads:

  < InsertVariableNameHere >

  Of course, you want to replace the text InsertVariableNameHere with the actual name of your variable.

  It can fail miserably because the process of generation of RoboHelp doesn't know how to cope. But in fact, it might work! You won't know until you try.

  And even if it fails, I may be able to offer another approach that you will overcome the problem.

  See you soon... Rick

• How to run execute immediate with variables

  Hi friends,
  How to run execute immediate with variables in v_stmt below?
  I don't know how to declare value I have here.
  

  Set serveroutput on;
  DECLARE
     i        VARCHAR (20);
     v_stmt   VARCHAR2 (100);
  
     CURSOR c
     IS
        SELECT sqlid FROM temp1;
  
  
  BEGIN
     OPEN c;
  
     LOOP
        FETCH c INTO i;
        EXIT WHEN c%NOTFOUND;
        DBMS_OUTPUT.put_line (i);
        v_stmt := 'select * from table(dbms_xplan.display_cursor('&i',null))'
        execute immediate v_stmt;
     END LOOP;
  
     CLOSE c;
  END;
  /

  Regds,
  Kunwar.

  You must first use a variable binding (named ': v' in the SQL statement in my example):

  set serveroutput on;
  DECLARE
     i        VARCHAR (20);
     v_stmt   VARCHAR2 (100);
  
     CURSOR c
     IS
         -- modified for a quick test
        SELECT sql_id FROM v$sql where child_number > 2;
  
  BEGIN
     OPEN c;
  
     LOOP
        FETCH c INTO i;
        EXIT WHEN c%NOTFOUND;
        DBMS_OUTPUT.put_line (i);
        v_stmt := 'select * from table(dbms_xplan.display_cursor(:v,null))';
        execute immediate v_stmt using i;
     END LOOP;
  
     CLOSE c;
  END;
  /
  

  However because your SELECT statement returns multiple lines, you need to adapt your code to process all rows returned (as already suggested in first response to your message).

  Instead of using the PL/SQL, I recommend you to generate a SQL file using only SQL, and then run the generated SQL file.
  For example:

  spool edx.sql
  set serveroutput on
  declare
  v_stmt varchar2(100);
  v_q char(1):='''';
  begin
  dbms_output.put_line('spool edx.log');
  for s in (select sql_id from v$sql where child_number >2)
   loop
    dbms_output.put_line('select * from table(dbms_xplan.display_cursor(' || v_q || s.sql_id || v_q || ',null));');
   end loop;
   dbms_output.put_line('exit');
  end;
  /
  spool of
  

  This generates a file similar to:

  spool edx.log
  select * from table(dbms_xplan.display_cursor('5rygsj4dbw6jt',null));
  select * from table(dbms_xplan.display_cursor('5rygsj4dbw6jt',null));

• why we use the symbol $ java variable?

  his_$ account_tota, $ b... can u give an explanation for this variable. What is the symbol of $ use? Why we use the symbol $ java variable...
  I need a clear and simple explanation for example...: P

  No real reason, you can do it if you want. But you don't have to - I certainly didn't, and I rarely see code it does.

  You should take the time to find a way to find information. For example, I just typed 'java variable dollar' in google and ended up with this as the first shot:

  http://docs.Oracle.com/javase/tutorial/Java/nutsandbolts/variables.html

  I quote:

  "In addition, the character dollar sign, by convention, is never used at all."

• With variable presentation month() function

  Hi all
  
  How can I use the MONTH() function in column answers, with variable presentation? I need to get the date month.
  I tried MONTHS (' @{tmp_date}' as date) but it doesn't work I get the error message.
  
  Thank you

  Hello

  If you select a single date value... go invite... then...
  Just keep filter on is invited to date column criteria of special relationship...

  Now, in the criteria take the same date column and apply * months ( column date ) *.

  So this column has the value selected and taken months of that particular date...

  try it this way...

• Can I upgrade to iOS 10 using a Mac with OS (10.8.5) Mountain Lion?

  Can someone tell me if I can sync to my iPhone 6 with iTunes using a Mac with the (10.8.5) Mountain Lion?

  This is what Apple is the list for the iPhone 7 that runs iOS 10.

  http://www.Apple.com/iPhone-7/specs/

  • Sync with iTunes on a Mac or a PC requires:
    • Mac: OS X v10.9 or later
    • PC: Windows 7 or later
    • iTunes 12.5 or later (free download from www.itunes.com/download)

  My daughter is running Lion on his MacBook Pro and was synchronize its iOS iOS 9.3.5 devices. The requirements for iOS 9 call for Cougar 10.8.5. It will never update via iTunes - always on WiFi - and I think that's how she got away with it. I don't know if it will work this time with iOS 10.

  Try to add a page to a pages document. It worked until now but just finished page 13 with text and photos and cannot add another page, using macbook pro with El Capitan and the most recent version of the Pages.

  You have placed your beam to insert at the end of your text on page 13 and then apply Insert menu: Page Break? In the v5.6.2, Pages I just add a new page to a section of four pages to this approach.

• I use an iMac with a wrong as a monitor graphics card?

  The graphics card on my iMac went wrong.  The logic board is OK and works otherwise OK.  Can I use the iMac with the graphics card bad as a second monitor in target disk Mode or use it as a monitor for a mac mini? The bad iMac is a model 2011 (of course!) with HDMI ports and Thunderbolt.

  I think you mean that the Display Mode target and any connection to the screen will have to pass by the graphics card. Whereas if you replace the bad graphics card, don't.

• Using Migration Assistant with no display

  I got my MacBook mid-2010 (2.4 GHz, 4 GB RAM, OS X El Capitan) for 2 years.

  It splits into two somewhere within 2 years.

  The MacBook was still usable, but it had to be on a desk. The screen was completely separate from the base. It still worked.

  I woke up a few days ago to find that someone had cut the display cable holding the MacBook set and turn on the screen.

  I bought an early-2011 13 "MacBook Pro to replace the dead MacBook. (Yes, I buy old Mac because the news is so expensive).

  Old Mac has been saved semi regularly, so I have an old backup to use for the new Mac. The problem is that just before the death of the former Mac, I downloaded a bunch of stuff that has not been saved. I really want the files that have not been backed up on my new MBP.

  Can I use Migration Wizard with an Ethernet cable and transfer of data from one, or Migration Assistant must be running on old Mac as well?

  I tried to connect (I'm sure that the computer is still running, it doesn't simply have a display) on the old Mac, plug the backup drive and I hope to do a backup hourly, but Time Machine did not only.

  Any suggestions would be GREATLY appreciated.

  If you use Ethernet or a wireless network to transfer data, Yes. If you can not download the files and file-sharing has not been activated on the old Mac, you must either get fixed display or put its internal drive in a closed Chamber.
