• Build an array of values of the difference

  Dear members,

  With reference to the attached LabVIEW 2010 Student Edition file...

  From the incoming data via the .csv "Reading of the spreadsheet", I want to display a picture of the difference between the n and n-1 data value if the data set is 10, 20, 25, 35, 50, then the difference will be 10, 5, 10, 15.

  I used the "Index Array" function to extract the n and n - 1 values (using the function 'Simulation' as the incrementer line index) however I can't find the way to build an array of these difference values and display them in the façade, which is

  10

  5

  10

  15

  It will probably be a trivial problem for more experienced LabVIEW programmers.  Advice or assistance is welcome.

  Kind regards

  Since you have 1 column of 800 lines, then use table to Index first to get only the first column.  This will give you a table 1 d of 800 items.  Then the idea to use this table, as well as the subset of the table for the 2nd through the remaining lines, subtract one from the other, work.

  I can't comment on the simulation loops because I don't have that and never used.

  

• build an array with 2 values assigned to 1 dimension

  I am wanting to build a 1 d array where the two values are assigned to each dimension.  For example:

  Index 0 would have a 1 and 4 are attributed to him

  Index of 1 would have a 2 and 3 which are entrusted

  Index 2 could make a 0 and 1 that are entrusted to him.

  So can I unbundle the arrayand grab the two les deux valeurs values of index 0, index 1, etc...  I want to put this inside a control of the typedef table.  Is this possible?

  What is the meaning of the index 0 vs 1 against 2?  What is the significance of 1 and 4 for index 0?  2 and 3 for 1 index? ....

  It could certainly be a 2D array.  The line index would be the equivalent of your current 0, 1, 2 indices.  The column index would be the equivalent of the if you want 1 or 4 or 2 vs 3.

  That's all just a matter of how you want to extract data out of the data structure and pass it to your other duties, such as Fieldpoint DAQmx, a façade, a text file...  If it is a 2D array, you can use the index picture, to get a line, column, or a specific line and column item.  If this is a cluster, you can use the index table to get your line, unbundling for the first or the second product off the part of the cluster.

  What data structure is the best one to use really depends on what you're trying to do with the data.  You want two numbers?  Do you want a number and a Boolean value?  You will need to figure out which is best for your application.

• Connecting leads to build the array in a VI script

  Hello

  I'm looking for a way to connect the wires to a knot of "generation table" in a script of VI.

  I have a table of entries that should translate in a table via node 'building the table '. I added successfully to the input terminals for 'building the table' node in a script of VI. However, the program fails when I try to execute a loop to wire all of the entries in the order. The problem is, all the sons of entry to the first element of the' generation '. Snapshot of the code is attached.

  Please suggest me a way to link the different elements at different entrances to the node 'building the table '.

  Thank you.

• How to build an array of 1 d n save it as a line on a free text

  Hello

  I write the code for the thermoucouple SR630 monitor. I want to go through the channels and then save the data to a text file or xcel.

  I managed to get the scan to work, and even record on file, but each number is placed under the previous, where instead I ideally would like to store all the numbers in a single on the same line scan, as it would have 5 columns of data for each sweeps of a single channel.

  Ideally an additional column would be also present on each line with a timestamp of the sweep as a whole.

  Can anyone help?

  code attached below

  Tema says:

  -Your changes bouquet now numbers in groups of 5, but they are still all one under the other. I can edit what they are separated by (ie. a tab, or space or by commas, etc.), but this only adds the item before the numbers all by always moving on the line below.

  I guess this is because the function is not wait all 5 numbers to build a single line to then send off in a whole ' writing in the text file. He sends every single number it is received?

  Can I use the function "pick up line" for loop on itself to build a single line?

  No, it's because the instrument is back one end at the end of the answer.  You save this file, and so each item will be displayed on separate lines.  I would use the Trim spaces to erase this inside the loop for.

  To add a time stamp, simply add to the string table before formatting in worksheet line.

• Build an array of several bays

  Hello

  I'm currently trying to build a program that generates and displays a Gaussian (graph) of several optical spectral results (achievements and each saved on a different worksheet file). Results will be all that I recorded with the wavelength and the name of the file will be each added a number:

  so I have several spreasheet files...   1. txt: 1550, 2. txt - 90: 1550, etc.-85...

  I want to put it all in a single table, or spread sheet so that I can view everything as 1 Gauss curve: 1, 2-90,-85 etc...

  can anyone help? I was thinking about a certain look to add the spreadsheet files I recalibrated in the loop, but this doesn't seem to be workin

  Something like that?  Load the take file column and built a table 2D for columns?  It may be transposed, I'm not sure.

  

• How can I build an array based on the check boxes "checked"?

  OOP! Just realize that this is in the wrong forum. Sorry
  
  Hey all the... I just have a question on forms in FLEX 2:
  
  I have a Repeater that is populated by a list of musicians from a XML file. Each artist is represented by a box and when the user clicks a "submit" button, I want to than this table to be sent to a php script.
  
  It's the vbox containing the details of the artist and the checkbox:
  
  
  < mx:VBox >
  < mx:Text text = "{artistRepeat.currentItem.name}" / > "
  < source = mx:Image
  scaleContent "{artistRepeat.currentItem.image}" = "true" / >
  
  
  
  "< mx:CheckBox data =" {artistRepeat.currentItem.name} "id ="cBox"click =" modifyArray (Object) "/ >
  < mx:Text text = "{cBox.data}" / > "
  
  < / mx:VBox >
  
  
  And the management is:
  
  
  
  public void modifyArray(item:Object):String {}
  If (cBox.data! = null) {}
  Return artistlist.text;
  
  }
  return artistlist.text = "(artiste =" + cBox.data+ "cBox.data+") "; » ;
  
  
  }
  
  
  He registered the artist as "undefined". I'll the sense here?

  EDIT: Never mind. I got it with this program. We finished.

  This is a user friendly like a speed bump hoof. Honestly, I will never use once I have the degree, unless Adobe stop using the Russians to write their error messages and a decent site somewhere be configured.

  I'm sorry, I feel pretty bad so that a program has almost caused several heart attacks. It is not good for my health this building :-)

  Anyway thanks,

• Build an array of object?

  Hey people BBerry...

  I hope that these issues become less basic, but...

  This is baffling me... I go through the "MemoryDemo" sent with the samples.  In the method below, if the getContents() returns a null value, it is filled with the "empty folder" (to use a term of database).  What I'm having problems understanding (and if someone could point me to the documentation on that, I would appreciate it) is how we can do it at all (at least based on playback on Java, I did until now).

  It seems one can declare which * seems * to be a table based on the structure of an object (this object is not on the same file .java) then add ot this table by a simple declaration of 'new '.  Is this correct?  Everything I've read so far on tables says that this should not be so.

  What I'm missing here?  Thanks in advance, (truncated) chiselled code is below (the rest is in the inventory of "MemoryDemo" app in the CustomerList.java file).

  -John

  // Members -------------------------------------------------------------------------------------
  private PersistentObject _persist;
  private CustomerRecord [] _customerRecords;

  CustomerList() private
  {
  _persist = PersistentStore.getPersistentObject (PERSIST);
  _customerRecords = (CustomerRecord []) _persist.getContents ();

  If (_customerRecords is nothing)
  {
  _customerRecords = new CustomerRecord [0];
  _persist.setContents (_customerRecords);
  _persist.commit ();
  }
  }

  You said

  "Foobar foo [] = Foobar new [5];

  It will give me a table which has 5 "ranks" and 3 "columns" (speaking in terms of a database)? »

  Not really.  All you have done is created of references to objects of Foobar 5.  You have not created the objects.  So, if you tried to do:

  String firstEntryLastName = foo [0] .getLastName ();

  This fails with a null pointer exception, because foo [0] does not exist.

  If you did then a loop initialization as I did above, you would have 5 ranks "empty."

  "it will work even if the class is elsewhere"

  Absolutely, although of course the class that should be able to find the p [package containing Foobar.

• Array of bytes Streaming playback

  Hello:

  Could someone french me some light, how could I impliment line three of the code in Labview?

  I have a pulse oximetry sensor conncected to Labview via a serial port VISA. Communication is very good, and I read 5 bytes successfully.

  However, each cycle, the context of the 3rd byte changes. Question is how can I build an array in the while loop (main), passing the value of octet 3 in another table.

  Byte0 | Octet1 | Octet2 | Byte 3 |  Byte4

  Number of sample to 1 / 1 255 255 100 255

  Number of sample2 1 255 255 255 50

  Number of Sample3 1 255 255 255 98

  The sensor will send 25 5bytes package, three times per second.

  The Streaming variable may represent 1 d table consists of 25 byte values #3.

  Then the rest of the algorithm would go on this Board on spidific, print the third value.

  For (i = 0; i<=25;>

  {

  InByte [i] = value ;} Streaming

  Serial.Print ("inByte [# favorite bytes print]" "");

  Could anyone recommend an appropriate approach rather tables? or it's the right path to take?

  I have attached the data of the page7 TCHF probe data sheet hanging in detail.

  Any help would be appreciated.

• Table of Build using Pseudo-file of waiting

  I'm moving to use a queue by simply creating a table.  I writing to a write DAQmx values in a loop at 50 ms, but I won't update the chart every 50 ms (for obvious reasons).  I use a global functional for transmitting data from a slower loop to 500 ms.

  Problem is that I get that each point of the tenth.  Y at - it an easy way to build an array and pass (without overwrite or skip data) to the slower without having to queue loop?

  Thanks for the help.

  Why not use a queue?  It is by far the most effective way to do what you want.

  What you have run in with the FGV is a race condition.  They you used it, it might as well be a local variable or a global variable.  FGVs do NOT prevent the race conditions in the way that you use it.  Here's a good article about the race conditions in the field of LabVIEW log:http://labviewjournal.com/2011/08/race-conditions-and-functional-global-variables-in-labview/

• array index

  Hello

  I built a small VI which displays a table 1 d of the images and a table the values of each image pixel 2D (it becomes 3D). I would like to have access to the array index to view the image with its pixel values (see attachment).

  If there is no way to access the index because it's an exit, I thought about a 2 column table where the first column will be composed of images and the second of all the value of the corresponding pixels 2D paintings. And the display could be done at the same time because it will be part of the same table.

  I don't really know if I can do it. This seems a little strange to build an array of 2D arrays...

  Thanks for your help people. I searched a lot but I've yet to find something similar. I enclose my VI (8.0), the FileInfo.vi becomes just a binary information and I read images all the (320 * 240 * 2) + 1016 bytes (frame size) + size of the header of the frame.

  It seems that Matthew has proposed a solution that looks like it will work (unfortunately, I can't do anything in LabVIEW for the moment because I upset him, and it is essentially suspended... I'm trying to give him a chance to redeem themselves before that I have to abandon the process and lose my other works... ). What I would say to you, is to ignore the idea of how you store the data in the way that you view the data. All you really need to see is a single image and a table 2D pixel values, with a kind of control that allows you to change the image and table 2D display.

  Grrr. Curse you LabVIEW! Who would have thought that you could not put 300 k items in a Listbox and expect it to work... I just killed LabVIEW; at least the automatic recovery tool works.

  So, now that it's the road, I can whip up an example. I have attached a quick example where you can basically copy the block schema and paste it into your vi (just replace table 3 and table of Image controls with the sons of your loop (you can delete the indicators related to these threads).) It is a very simple GUI that allows you to drag the cursor to select an image, and when you do, it will display the appropriate image and a table of pixel values. The node property is here just so that when you run the program, the correct values will appear even before you click on anything.

• reading of the worksheet into an array of strings

  Hello

  I need help to build an array of 1 d (string) from a MS Excel file. I tried to use spreaaadsheet reading / read the file of the measurement. I am unable to do this. The excel file contains alpha-numeric data. Please suggest with a few example screws.

  entry would be the path of excel file

  output would be a table 1 d of channels

  Thank you

  Is it necessary to be an Excel file or you use Excel to open the file? If there must be Excel, then you may need to use her Active X (for example you can find in this forum), otherwise just save it as a csv file and use the worksheet vi reading with ',' as the separator.

• Name of building resource?

  Hey Gang,

  It was a frustrating day.

  I'm building an application driver for the PCI-6021 in native C++ code.  I use DAQmx driver inside.  It seems that the driver needs C (table of constant of type character) type strings for specifying "meter."

  Everything works fine when I created it below and which pass to the function:

  My meter [10] char = ' Dev1/ctr0. "

  But, I have to build the array of characters in molding and inserting integer variables for numbers of device and the meter.

  I can generate strings that have the right text in them, but I didn't understand how to cast that into a variable that will work with the command.

  I know it's more a matter of C/C++, but I will really appreciate any help.

  Thank you

  Roger

  Eureka!

  I've found a workaround.

  I create a table of character literals:

  numbers [9] char = {'1', '2', '3', '4', '5' ', 6',' 7 ', ' 8', 9'};

  int MyIntArg = 1;

  Then replace the character:

  MyCounter = ' Devx/ctr0. "

  MyCounter = [3] numbers [MyIntArg-1];

  Phew!  On the following problem!

• Array of values Boolean cluster? bits?

  I was trying to * make * a cluster in one area as little as possible, and I tried to build an array of Boolean 3, then use the table to the cluster service to this cluster.  However, it seems that there is that a fancy way of labview handle Boolean values.  something like a 9-bit thingy?

  Many years ago I remember reading how hardcore CS people interpret Wicks... little big "endianness"? I also saw how labview can convert an integer in 9-bit something like that.

  in any case, my question is, is it possible to do a 'cluster' of 3 items from 3 Boolean constants without using "bundle"?

  Thank you.

  The default cluster is 9 elements, right-click to change.

  (As a side note LV implements Boolean as U8, so a byte for each.) If you want the bit optimization you could hide all to a single U8 like flags - type C)

• Table 2D array in alphabetical order

  Hello

  I have great picture 2D is where thousands raws and each cru have 5 columns. Now, I want to organize this wide range of alphabetical order. First columns is arranger, is where the information chain, other columns are digital information only.

  Advice where I should start?

  THX

  1. build a cluster containing the string as the first element and an array of numbers as the second element.

  2 - build an array of bunches against the elements of your tables

  3. sort the table of clusters
