How do I create a table of 3 data elements for each trial and have it updated instead of waiting until the end of the program?

I am trying to record 3 pieces of data, all (software) timing in ms (in U8 integers). I managed to finally get each data in the right column but now it doesn't record anything in the table and it doesn't update the numeric indicators during the experiment like it should. I can't figure for the life of me what I did wrong. I know at least the trial part of the program works, but so far the data recording part is giving me a headache.
Thanks

Why it is not reporting the data is easy; fixing the program may not be. LabVIEW uses a dataflow paradigm. This means that no part of the program executes until all of its data inputs are availble. In your case the table and the array functions driving it are fed by outputs from the outer while loop. Thus no data gets to the table until the while loop has finished executing (which is at the end of your experiment). One possible approach would be to store the data in a shift register and move the table inside the loop.
Many experienced LV programmers try to avoid or minimize the use of sequence structures and local variables to read and write to/from front panel objects. We use a state machine which is a while loop with a case structure. Queues can be u
sed to pass data between the user interface and the data acquistion loops. This subject is too involved to be handled in a brief posting, but if you search the archives and examples you can learn more.
Also, be aware that software timing can be problematic if you are using a desktop operating system. If the OS decides to check the net for software updates or something you could have large discrepancies in your timing. These might be rare, but there is no reliable way of detecting them. I have built several systems similar to what you seem to be trying to do and have never been successful with software timing.

  • How do I create a table with header cell tags for screen readers in indesign cc 2014?

    In order to create a table that's readable for screen readers, I need to give the cols and row values like headers. This way the screen reader should be able to understand what the value in it's corresponding cell is. But... how do do this?

  • How can i create a multilingual website with a menu for each one?

    I have all the pages in spanish and the same pages in english ej. Contacto and Contact ...should be sister or child pages? I need two diferent menus (one for spanish pages master, another menu for the english pages master) but the menu feature mixes everything. Is there a solution to this?
    Thank you

    Hi Carme,
    It might be easier for you to set up your menus manually, so you can control what is the the Español and English menus, rather than fuss with child and sister pages.
    Click and drag out that menu widget that you want to work with > click > click on blue arrow > window opens > under "Menu Type" choose "Manual". Then you can manually enter the titles for and English Language menu. Get that working exactly as you want it to ( colours, roll-over etc ) When you're happy with that one, copy and paste a duplicate of that English menu. You can then go in and change all the English to Spanish. When these are done, then go through both menus and link the buttons to the appropriate language pages.
    This way, you don't have to worry about page higharchy, sisters, siblings or anything else. You have better control. It might also prove helpful in the fact that there have been issues in the past with pages navigating once uploaded to the web, who's page names consist of special character language markers like: ñöäãũ
    You may want to consider when naming your actual pages that the search engines will be using, ( i.e samplepagespanishpage.com* ) to omit these special characters. Sometimes they cause problems and the site won't work properly. However, if you manually do your menu names, these special characters can be used and it shouldn't cause an issue.
    * - If you check into the "Page Properties" under "Metadata" - "Page Name" is where you may want to consider omitting the special characters. "Page Title" I believe you can keep the special characters. This is the information that people would see in Google.
    I hope this helps.

  • How do I create a Table of Contents in InDesign CS6 for print that easily converts to epub?

    How do I create a Table of Contents in InDesign CS6 for a print book that easily converts to epub? 
    Can anyone point me to a link for a step-by-step (not a video) on setting up all the elements of a print book properly (pages, table of contents and index) so they will convert and reflow perfectly from print to epub in InDesign CS6. This is not about building an ebook from ground up, but taking 50 backlisted print books (converted from old versions of Quark to InDesign) that now need to be converted to epub formats.
    OR could someone point me to the link in the Adobe InDesign CS6 support that explains how to create a Table of Contents for a print book (5.5" x 8.5", 288 pages), one that will convert when the file is converted to ePub (for MAC OSX)?
    Just downloaded the 706 page inDesign CS6 reference manual from Adobe <http://helpx.adobe.com/pdf/indesign_reference.pdf>  but there's not even a search feature on the pdf file.
    Up until this week, we have only done print books, creating the TOC the old fashioned way, as a fixed page, comprised of two columns: page numbers and chapters/subject. The files I have created are taken by our printer and printed beautifully.
    However, when I convert the same book to epub in CS6, the character and paragraph styles converted beautifully - but everything else is all over the place! The table of contents is on different pages, the columns split apart. That goes for the page contents as well - everything is all over the place. when it's converted to a pdf -- total perfection. Never any problems converting with perfection to pdf format and reading those on the various readers.
    (Thank you so much in advance for any help).

  • How Do I Create A Table?

    I will admi9t that I am the newest of "newbies" to SQL Server so I pose the basic question : How Do I Create A Table in SQL Server? I read in a book fairly recently how to do this but have forgotten.
    Steve R. Burrus

    "SQL Server 2008 supports the creation of tables using T-SQL, the SQL Server
    Management Studio (SSMS) Object Explorer and the SSMS Database Diagram Editor. Regardless of the tool you choose, creating a table involves naming the table, defining the columns, and assigning properties to the columns. The visual tools (such
    as Object Explorer and database diagrams) are usually the best starting point for creating tables.
    Using Object Explorer to Create Tables
    The Object Explorer in SSMS has a Tables node under each database listed. You can add tables via the Object Explorer by right-clicking this Tables node. As shown below the
    New Table option displayed after you right-click the Tables node in Object Explorer. The top-right side of the screen shown in bleow.it is the table creation screen that allows you to enter the column name and data type and to set the Allow
    Nulls option.
    The data entry area under Column Name is a free-form area where you can define a column name. You can select the data type from the Data Type drop-down, which displays
    the data types available with SQL Server. The Allow Nulls option is Boolean in nature and is either checked or not checked. For each column selected, a Column Properties section is displayed in SSMS, providing a myriad of additional properties that you can
    assign to each column.
    Using T-SQL to Create Tables
    Ultimately, all the tables created with the visual tools can also be created by using T-SQL. As with many of the SSMS tools, database objects can be resolved or scripted into T-SQL statements.
    Let’s examine the T-SQL syntax to better understand some of the table creation options. so let's create a Table name
    test.Customer which has a 5 columns of CustomerID, LastName, FirstName, CreditLine, and CreationDate. so when you execute the bottom code you will have the table. 
    --START with USE command to tell the sql server which database you want to create the table on, this case we want to create the table on Adventurework2008 (it’s a Sample database)"
    USE
    Adventurework2008
    CREATETABLE test.Customer
    (CustomerID
    INT IDENTITY(1,1),
    LastName
    VARCHAR(50)
    NOT NULL,
    FirstName
    VARCHAR(50)
    NOT NULL,
    CreditLine
    MONEY SPARSE NULL,
    CreationDate
    DATE NOT
    NULL)
    GO
    I hope this helps answering your question more or less. Goodluck

  • How do I create a table that breaks for new pages?

    I'm running Pages 5.5.1 on OS X Yosemite 10.10.1 and am having difficulty understanding table behavior.
    Scenario 1 - I create a new file and insert a table at the top of the first (blank) page.  It automatically is selected for Object Placement>Move With Text.  If I add rows to this table, Pages automatically adds a new page and breaks the table so that additional cells appear on the new page.  All well and good.  If I change the Object Placement to Stay on Page, the second page and those cells disappear.
    Scenario 2 - I create a file and first add a few lines to the top of the first page.  Then, I insert a table below those lines.  It is also automatically selected for Object Placement>Move With Text.  When I add rows, the table does not break for the second page, but the entire table jumps to the second page.  If I change the Object Placement to Stay on Page, I can then slide the table back onto page one, but as in Scenario 1 the portion of the table which would continue onto page two disappears.
    So, how do I create a table that I can add to a page which is not blank (as in Scenario 2) which will break automatically onto page 2 instead of jumping, and so the rows appear on page two (not disappear as I describe above)?
    Thank you for your help.

    The inline table is supposed to break but like most things Pages 5 it is buggy and erratic in its behavior.
    Use Pages '09.

  • How do we create a Table pool

    How do we create a Table pool

    You need to use WLST online. I am not sure what your exact requirements are but one good way of working this is to have a WLST script that deletes all your WL customisations, like connection pools, JMS Servers etc and then creates it. That way you can run the same script repeatedly and it will get everything up to date for you. However you have to remember that everytime you add something new you need to update your delete section. Also your deleting should not fail if the item does not exist. I hope that makes sense!
    As to the specifics of WLST examples to do this then check out the WLST examples in CodeShare.

  • How can I join 3 tables while extracting data from SAP R/3?

    I have 3 tables with the following columns
    Emp table (emp)
      emp_id
      emp_name
      emp_add
    Dept table (dept)
      dept_id
      dept_name
      dept_loc
    Location table (loc)
      loc_id
      loc_name
    Now. If I want to select data from loc_id = 10 and emp_id between 2000 and 3000
    How to join these three tables while extracting data from R/3
      join condition
       loc.loc_id = dept.loc_id
    and dept.dept_id = emp.dept_id
    and loc.loc_id =10
    and emp.emp_id between 2000 and 3000.
    Could any one let me know the procedure to extract this data into BW system.

    Hi,
    shouldn't your join condition be:
    loc.loc_id = dept.DEPT_LOC
    and dept.dept_id = ??
    If you can join the three tables then create a generic datasource (RSO) based on a view (create your view with your join in SE11).
    Enable the loc_id and the emp_id as selectable in the datasource so you can then select the values from a BW IPack.
    hope this helps...
