• Find a value in a table

  Hi, I'm trying to find the index of a value in a table, I know that it is a VI called 'research in a 1 d table' but there is my problem: Let's say I'm looking the value 25 and in my series of measurement, there like 24.998 and 25.001 but not 25, this VI will not find the value 25 although he went close enough , so basically I try to inplanta a tolerance system making it able to find with precision +-3 or 4 on the index, doing someone something for this?

  Thanks for your time

  I wrote this for a similar job, but it could be used for your application.  Just use the vi attached in a loop to check "in range" and returns the index of the loop of the first occurrence.

  Hope this helps

• maximum values of five table 2d

  Hi, I have a vi that reads in the values of a 2D array, and then uses this information. I currently use the vi 'Table Max and Min' to find the maximum values of the table. It can be beneficial for my application find the maximum of 5 or any other number of values in the table. My current plan is to use a loop that detects that the maximum value of the original array and then subtract this value and repeat the operation once 5 or greater. However, I believe that it is innefficient and can take a long time in a vi that must run pretty quickly. I would like suggestions. Thanks in advance.

  It would be a bit faster

• Find most common value in a table of enums

  Hello

  I'm looking for a stylish way to find most common value in a table of enums

  My being of enum:

  0 - close

  1 - open

  2 - undefined

  For example, if my table contains:

  Close, close, open, close, close, open.

  The most common value would be 'Closed'

  I created a very personalized VI which allows me to get the desired result, but I'm really not proud of doing it this way, just simply because I need to change if I add a new value to my enum...

  If anyone can share some ideas to enlighten me, I would REALLY appreciate it.

  Thanks in advance!

  I don't know, I'd go the yard road, to propose, he could save a single iteration since you know 0 is the first point of departure, but you then must deal with the determination of lengths and dealing with missing values that return-1, etc..

  If you really expect of very large tables, I would have moved my previous version which is supposed to be quick to write in another simple method of counting.

  

• kindly tell how to use the unique value of a table with the index 0

  kindly tell how to use the unique value of a table with the index 0

  Hi
  
   
  
  Yep, use Index Array as Gerd says. Also, using the context help ( + h) and looking through the array palette will help you get an understanding of what each VI does.
  
   
  
  This is fundamental LabVIEW stuff, perhaps you'd be better spending some time going through the basics.

• Problem adding values to a table with the state machine architecture

  Hello

  I currently have a problem that I have to build a program using state machine architecture and now I want to add a value in a table whenever you press a button, but I would like the table to add the new value, rather than deleting the last value. I can't seem to figure out how to make this work without using while loops and similar. It doesn't seem to work properly.

  It is in the case of measurement.

  The idea is I draw several lines then it records the length of the lines in a table and then I'll take one average this so I can convert pixels into real life SO units. But right now I can't seem to add the information in the table.

  There is a little screw Sub, but I think that they should not be important for this question please!

  What's the problem with just the table help build?

• Not able to enter the values in a table.

  I'm not able to enter values in any table that I create in labview. By mistake I pressed a key on the keyboard, and every time I try to enter values in a table, a window pop up opens and resets the value to zero, if I make selection from there.

  I enclose the screenshot.

  I'm with Altenbach on this one.  Looks like you turned off your Autotool.  If you go to View-> Toolbox, you will see the tool Palette.  Make sure that the top button/led is on.  Who will ensure the Autotool on.

• Get the current index value of the table control

  I have a table control 1 d on a panel that contains a value of temperature curve that I send to a temperature controller. The values in the table are not unique, because for example 40.5 degrees in the table could represent 40.5 degrees on the cycles of cooling or heating. I could have severat heating/cooling cycles programmed into the table. I would like a way to read the array index of the currently displayed item in the array in the up/down control of index on the left of the table control. I could then run curves partial temperature easily by neutrophilia a starting point on the curve in the table control.

  I don't see a property that I can use to get this index value. Anyone have any ideas?

  Thank you

  J

  Use the property 'index values. It will be the first item of the output of a 1-d array.

• Setting the value of a table of ActiveX control

  When controling a VI through ActiveX, how is possible to set the value of a table control?

  With digital controls, I have a problem: I just use SetControlValue and it works well:

  til SetControlValue ('y', 4) for example.

  However, in trying to do the same thing with a table, the control's value becomes an empty array:

  til SetControlValue ("arr', [3-4-5]") for example.

  What is the right way to do it?

  Hi Calvin,

  Have you tried passing a string and convert it to an array entry?  You can also try to use a 'matrix' control, rather than a table, as they are handled a little differently.

• Find the minimum value of the table in time...

  Firstly that it is not "find the min value in the table.

  It is:

  I have a table that changes its values at each iteration, and I want to compare the new values with previous values and make a new array with the minimum values...

  In C++, it would be like this:

  int main() {}

  int array [8];

  int min [8];

  int i;

  for (i = 0; i<>

  min [i] = 1000000; Initialize minimum table with a high value

  }

  {while (1)}

  Array = update_array ();

  for (i = 0; i<>

  If (array [i]<>

  min [i] = array [i];

  }

  }

  do things...

  }

  return 0;

  }

  IM new to labview and it always confuses me a lot...

  Thanks in advance.

  Using the function Max & Min regular (not table Max & min as you know) with tables and a good will of employment registry change.  Max Min &, as most of the digital functions, is polymorphic and works witt tables as well as scalars.

• Read integer values to worksheet and display the values in a table

  Hi all

  I have integer values to read from a worksheet and display them in a table. I uses 'Reading of the spreadsheet file' mode 'integer '. I want to display these values in a table. The problem is the table takes only 2d-array of string as input but not an integer.

  It works fine if I change 'Worksheet file playback' mode to 'integer' to 'chain', but I want to read integers and must use integer values for calculations more. Please give suggestions on the display of integers to a table.

  Thank you.

  Do not take not piece-by-piece just convert as a whole. See the attached example

• acquire a signal and the rms value in a table every second

  Hello everyone,

  Sorry, but I am known in the world of LabView and I'm going crazy because I can't understand how to do a simple thing (or what it tends to be in my mind).

  As said by the object,
  my wish is to acquire a digital (a through the DAQmx) continuous (it's ok for this part), get the RMS (or average) of such acquired signal (thanks to the Amplitude and levels of measurement, for example) and put the value in a table (1 d); and, every second.

  In one sentence: acquire a signal, the average value, put in a table, and then restart each second. In the end, for example, the program for 1 minutes gives me 60 value in the table.

  Is someone can help me?

  Thank you in advance.

  Viviogs.

  First of all, I'm not sure that you can be sure exactly a second measurement using this technique.  If the precise timing is important, I think that you need a timed loop.

  That said, if the only problem you have is how to write the table indexed in a spreadsheet, you just need to use "Write in the worksheet file."  See here.

• Gears - error when you try to insert values into a table with multiple columns

  Hello

  I started playing with the gears and SQlLite today and I get an error when I try to insert values into a table with multiple columns.

  I have:

  var db = google.gears.factory.create('beta.database');
      db.open('developerSet');
      db.execute('create table if not exists Developers (DeveloperName text, DeveloperAge int)');
  
      var devName = "Davy"
      var devAge = 32;
  
      try {
          db.execute('insert into Developers values (?, ?)', [devName, devAge]);
          alert('success');
      }
      catch (e) {
          alert(e);
      }
  

  I get the error:

  net.rim.device.api.database.DatabaseException; insert into developers values (?,?): SQL logic error or missing database.

  I use this reference: http://code.google.com/apis/gears/api_database.html

  Everything works if I have only one field as:

  var db = google.gears.factory.create('beta.database');
      db.open('developerSet');
      db.execute('create table if not exists Developers (DeveloperName text)');
  
      var devName = "Davy"
      var devAge = 32;
  
      try {
          db.execute('insert into Developers values (?)', [devName]);
          alert('success');
      }
      catch (e) {
          alert(e);
      }
  

  I use the plug-in Visual Studio 2.0 for 2008 that are running Windows XP SP and Simulator 2.13.0.56

  Thank you

  Yes, a SQLite database will persist between battery pulls.  The database is registered either to internal MEM or removable media (not the device memory), depending on which is available on your device.

  In general, its not considered a best practice to remove your table as soon as it is empty and re - create it again when you want to add data.  This adds extra overhead fresh for the final, delete and insert first for a given table.  Instead, define and finalize your drawing before you create your table.  Once created, review the static schema.

  That being said, for development purposes, it may be easier to provide an easy way to drop your tables while you develop your schema.

  See you soon,.

• Please how can I use a value in a table of the adf in an actionListener to a button I created in a popup and thanks

  Please how can I use a value in a table of the adf in an actionListener to a button I created in a popup and thanks

  What is your version of JDev?

  Actually your question is not clear to me, but as I understand, it is you the table in the page and you have popup inside this popup you have the button you need when you click on the button to read the value of the selected table row. In the listener action button, so if you can get the current row of the table and after that you can get any attribute of the line as:

  DCIteratorBinding iter = (DCIteratorBinding) BindingContext.getCurrent().getCurrentBindingsEntry().get("TableIteratorName"); // from pageDef.
  Row r = iter.getCurrentRow();
  Object value1 = r.getAttribute("attribute1");
  Object value2 = r.getAttribute("attribute2");
  

• To find the nth higher/lower value in a table

  Hi all

  I have a question

  in the table a1(empid,sal) are the 2 columns

  EmpID sal

  100-5000

  105 7500

  110 3500

  087 11136

  14336 95

  I didn't want to write the query that will give me the 3rd highest salary. or generalized to find the nth more eleve/nieme the lowest value of the table.

  Note:-Rownum and Rowid must not be used

  Thank you

  Hello

  You can use a generic result of queries to find nth highest salary...

  Just put the value of N in the query, you will get the answer...

  Query:

  SELECT E1. Salary OF EMP E1 WHERE (N) = (SELECT COUNT (DISTINCT E2. Salary) OF EMP E2 WHERE E2. Salary > = E1. Salary);

  hope you got the answer...

  Check if it really helps...

  thanxx...
