change individual items in a 1 d table

First of all, forgive me because I am very new to Labview (8.5 full). I still read Labview for everyone but I'm starting to build Subvi for a program of DA, I need to write. The code is attached for a routine (simple) that allows the user to manually load the values in the tables 1 d. These tables are used to a poly (already written) adjustment curve to generate the coefficients will be calibrated sensor nonlinear optical Blackmer.

What I tried to do is to initialize an array at their entrance to the Sub - VI he then wait for the user to enter a new value in the input box, select the cell you want to change and click on the "LOAD" button to write this value in the table cell. What is happening is that the table in its entirety from sems to initialize every time you click on the load button. I deliberately kept the initialization routine outside the loop of 'LOAD', but I don't seem to matter.

It's my first time with graphical programming and I'm not sure I'm even a table. Where is he? In the thread? I formed it and display it, but I don't see a picture as in Visual Studio, Pascal, etc.

I am even close to being on track or have I missed something important in my efforts?

You must keep your table into a shift register. (see attachment).

Also:

  • Your flat sequence has no purpose because the order of execution is entirely determined by data flow
  • Use the appropriate data types. If you want to DBL, initialize the array as DBL. If you want, use the indicators and controls around.
  • Your inner loops use 100% of CPU do nothing more of the time, you don't need at all.
  • Also, your outer loop consumes 100% cpu. Use a structure of the event.

You should also familiarze yourself with the stream, because the major part of your code is very imperfect. For example, your controls will have to be in the innermost loop in so that they can be read during execution of the inner loop.

Use my example: a loop, the structure of an event.

  • Cannot change individual file Associations

    I can't change individual file associations. The most I can do is assign an application given to 'all' the files it can open or just to 'some' of the files it can open. (And someone else chose it as 'some' is.)

    I'll give an example:

    I installed QuickTime Player. When I look through the QuickTime Player file associations, I see that one of the formats that QuickTime is configurΘ for dΘmarrer is DV. I don't want QuickTime to open the DV files. I have another request for this. However, I can't remove the check mark from the DV file association. In fact, I can't remove all checkmarks of the files that QuickTime is set to open.
    So my question is: How can I change the file to a unique and specific file type association?

  • How to change the PCTFREE parameter for an existing table

    How to change the PCTFREE parameter for an existing table?

    Guys can you help me please

    Hello

    Of course it is possible.
    In this case you would export the table from the database (using old style exp)
    Start the import with the index_file option to generate the table/index instructions
    Modify the file created and updated the PCTFREE and remove any that need to be performed (default, if I remember correctly, he comments on the statements of the Index)
    Run the file for the table and the index created
    After that start the import with the option "ignore = yes".

    Make sure that you export only this particular table using "tables =
    Also in importing the "ignore = yes" will also be important data that still exists.

    In my view, however, this is not what you want to do. It's more complex, sensitive failure and the table should be deleted, so users are affected unnecessarily long.

    Success!

  • Table of clusters change an item in several loops

    Hello, sorry for my bad English.

    I have an array of clusters, clusters of other tables and controls.

    I want to access each control individually in the table, in several loops to avoid data loss. I know that I can refer to each control in the cluster and change its values, but he changes the values in the table too.

    Or I can access the cluster I want in the table, but I can't access each control individually.

    If I do something like this im going to given loose.

    So what can I do?. What is the most effective way to do it?

    Thanks in advance.

    Looks like you really need, it's a reference to value of data on the table.  Then, you use the Structure of elements in Place to access the array, the index of the item you want, and then ungroup by name to get the desired control.  Do the reverse to clean it up and save the data.

  • How to update the table when change list item in the classic report

    Hello
    I worked with apex 4.2 and I create normal classic report with list (named loved) select a column, now I want to update the table when the user changes the list with the new value, I can't create a dynamic action to do this, I create checkbox with the primary key and the loop for check point to update the table but I can not get the value of the list item. and for more speed, the user want to do it when changing the value from the list.

    My question
    1. how to do it in javascript and get the value of the list item and update the table with the new value
    2. do I have to use the API to create the list item so I can get the value of the report item or what.

  • Is there an easy way to replace individual items in an array of strings to another table of striing?

  • Individual items in a 1 d array can cause different labels and if so how can this be done?

    Development of a test bench to measure tension on a DUT.  If several measures, through the installation of module DAQmx for several channels & individual samples, with the results stored in a 1 d array can items in the table named accordingly to the measuring channel?  For example 0 element can be channel 21, part 1 can be channel 30 or name can be for the element 0 + 5V and would be to the item 1 + 1, 8V.  If so how is this possible?  I looked in the property unsuccessfully node attributes.

    You can't do it with labels.  All elements in an array must have the same attributes.  Something that I've seen done is use an array of clusters.  The clusters contain a string for the name of the channel and a data table.

  • Allow the user to change the items in web application that they have not submitted

    Is there a way to allow a user to change/remove the elements of web app that they have not submitted?

    I did more than 400 pieces for the user via a .csv spreadsheet. I want the user to be able to change or remove these via an editing page of web app, I'll set up, but because I downloaded the .csv file, apparently, that another user cannot do this.

    At present, the only way that I know that this is so by the user submitting each element individually.

    Anyone know of a way to attribute everything to this user as if what he presented to them? Perhaps via the .csv file?

    Yes. In admin, you can change each element of WebApp to be attributed to a customer with the "presented by" in the section 'other Options '.

    You can also import/export this value, but in the CSV file, it is labeled as 'EntityId' - and you must use the system ID/ID of the entity of the client here.

    Otherwise, to allow anyone (who is connected) to change any element of WebApp, you must change the setting in the configuration of this WebApp by checking the option "anyone can edit items.

  • Find/change the question numbers and create the Table of contents

    Hello! I need help to find all my item numbers and apply a paragraph style so I can use them to create a Table of contents page.

    The sample numbers

    #12345

    #12345-5

    #12345-20

    #12345-ABC

    #12345/N

    I tried to enter #^? ^ ? ^ ? ^ ? ^ ? in the search/replace and but it is exactly 5 characters after the sign #. I wonder if you can find all characters starting by # and up until the last characters.

    Once I found all item numbers, how can I apply the paragraph style to have these characters after the sign #? Because I only want to show item numbers without the # sign on the Table of contents/Index page.

    In addition, I have InDesign CS2, which have no function GREP maybe I can do this without the GREP?

    I really appreciate any help. Thank you very much.

    Are your numbers by themselves in a separate paragraph? OTHERWISE you can not USE the table of contents feature to list all the numbers.

    If are, then just look at # in find/replace, then set it to change formatting a new paragraph style (you must create this style in CS2) that you want to include in the table of contents, then as you say, you can use find/replace once more on the history of the TOC to remove the # of all numbers.

  • Dynamically change the item values

    Hello

    I defined a form based on a table with the following values.

    consultant_name - popup LOV based on a sql query
    month popup LOV based on a sql query
    year popup LOV based on a sql query

    Bill rate - screen only
    our cost-screen only

    I want to display bill rates and our dynamilly cost whenever I change the values of the 3 LOVs.

    To do this, I defined a dynamic action
    When event: change
    elements: consultant_name, month, year
    no condition
    real action: run pl/sql

    DECLARE
    B_R NUMBER (4.2);
    O_C NUMBER (4.2);
    BEGIN
    SELECT BILL_RATE, OUR_COST IN B_R O_C OF STAFFING WHERE THE CONSULTANT_NAME = V('P3_CONSULTANT_NAME) AND
    YEAR = V('P3_YEAR') AND MONTH = V ('P3_MONTH');
    : P3_BILL_RATE: = B_R;
    : P3_OUR_COST: = O_C;
    END;

    But during execution, it does not all values of bill_rate and our_cost also do not show any error message as data not found.
    What mistake I made?

    Hi Steve,.

    have you written p3_year or P3_YEAR? Because it is case-sensitive. It is the same of the selected item.
