Table 2D-string in a void 2D array

• subset of table truncate the end of the 2d array

  The intention was to make a program that would generate asynchronous several different signals in a buffer.  Then something would consume the buffer - an output daq, and signal processing.  I created a dummy consumption which takes only 1% over the beginning of the buffer.  Whenever the buffer is smaller than the specified size, more signal will be added at the end.

  I ran into a problem where the function of the subset of the Array is truncate the end of the subset sometimes, so I disassembled the program until a congruent portion of the code exists to cause the problem.  It seems to be the use of memory or related allowance.  Maybe I'm doing something that I shouldn't be, but it seems like a bug in labview.  In the block diagram, I have a note that shows a waveform wire that goes to a case statement.  Just remove this thread causes it to work properly as seen by the consistency of the waveform on the front panel.

  I'm using Labview 2014 (without SP1)

  I would be grateful for any ideas.

  To work around the problem, use the copy always at the moment. I'll try to engage someone R & D of LabVIEW to get the last word.

  In any case, it seems unnecessary to carry all these t0 (which is always zero!) and dt (which is always the same. Constantly from waveforms to bays and back just really clutters the code. If dt would be different between the waveforms, you would have a much bigger problem .

  I understand that your actual code is much more complicated and what you show is just the tip of the iceberg lettuce.

  Here is a general overview of execution project ideas.

  • Use 'building the table' (concatenation mode) instead of "insert into array. It's cleaner.
  • Use simpler and easier to read the code to find the size of the table smaller
  • Only use tables. You can define once and dt for all graphs.
  • Use the correct representation for buffer size controls.
  • Don't place unnecessary sequence structures.
  • I don't think that you really need that local variables, the terminal is written often enough (stops you extra copy of the immense tables in memory!)
  • Do not know what is the structure of matter, but I left it in for now.
  • Add conditionally empty bays, just wire the table via unchanged instead.

• How to read the table of string returned by the DLL

  I developed DLLS in labview that takes 2 input parameters as a string and returns an array of strings in return. How can I read back this array returned strings in labview? I tried to return a string and I can't able to read. But how to read a table?

  Is the signature of the function – void GetLoginInfo (char [] DBPath, char [UserName], LStrHandleArray * table)

  Shrinivas

  I found the solution. When you configure the node to call a library function, the argument (in which we expect an array of string) type should be chosen as "Adapt to the Type" and data format to be "pointers to the sleeves.

• Indexing of a table with string instead of the number

  In TestStand, there are 2 ways of indexing of certain types of berries. (Seems to be arrays of containers)

  For example, in a sequence containing one step, called statement, you can contact this step in two ways:

  RunState.Sequence.Main [0]

  and

  RunState.Sequence.Main ["Statement"]

  (in fact, I can also use the id of the step, but keep, more simple with these 2 methods)

  Is there a way to create this type of table myself, in order for me to use string indexing? (or is it only possible on certain Types of OR)

  As can imagine you, this works for any array of containers.

  You just need to assign names to the elements. You can do this in the sequence by selecting an item and pressing F2, editor or by setting the PropertyObject.Name programmatically.

• Insertion of several strings in a 1 d array

  Hi all

  I am a beginner new to LabVIEW, so go easy on me. I tried to do for far too long and I thought I'd give forums a shot. I'm taking a picture 2D channels and their entry in a 1 d table. Sounds pretty simple, but for some reason, I just can't get it. The table then feeds into a ring of text. Thus, for example, say I have a table of dimensions 4 x 2 [a b c d e f g h], the output I want is a 1 x 2 [abcd, efgh] matrix. However the table could be 4 x 4 or 4 x 6, so this is not fixed. The ring of the text allows the user select among the options (2 in this case).

  I hope that I have described my problem clear enough for people. Taking the strings in the 2D array and put them in a chain are as close as I got what I want. I also tried the table to a spreadsheet string, but he gave me a long string. Unless there is something blatantly obvious that I'm missing, could someone give me some advice? Also, I would just add that everyone telling me to go read the tutorials, etc. of source material. Believe me, I have. Carefully.

  I have included a picture of the section of code that I'm trying to make it work. And Yes, I realize that it will not be anything to the ring of text entry right now, which is currently just how I saved it.

  Replace the while loop with a loop For.

  Do not use the subset of the array, simply use the tunnels of automatic indexation.

  Use the concatenation of strings on your table 1 d and you will have a single string.

  Use the automatic indexation on the exit tunnels and you will have a table 1 d of these channels.

  (You may need to convert the 2D table before feeding it into the loop For).

• Table index String function?

  Using the Index of an array of strings, said "the connector pane displays the types of data by default this function is polymorphic." but it doesn't seem to be polymorphic. I can only call a table 1 d of channels in the table of chains and a string to a string. Miss me something really obvious or aid is wrong.

  I'm not exactally new to LabVIEW, but I didn't realize that now (thanks to quick drop) that this feature exists.

  Other the ability to concatenate the input string with the indexed array element string why Index of array of strings does exist? Is there any other reason to use instead of the array index generic function?

  With the help of LabVIEW 2010.

  Steve:

  I went ahead and filed a CAR (#279806) documentation to get this corrected. Thanks for putting in place!

• table, equivalent string.replace

  Hello

  What can I use as a method to replace on a table?

  Replace the method of the done String class a number of things.  First, it locates a match of what is supposed to be replaced and secondly it replaced by something else.  For a table, you will need to take into account these two steps.  The first step could be carried out using the indexOf() method.  The appearance of replacement could be as simple as the reallocation of the element which is found at index... table [i] = something again.

  So if you wanted to combine them into a single line of code, that would be something to the effect of...

  Array [Array.IndexOf (Old)] = new;

  Example:

  var array: Array = new Array (2,3,4,5).

  Array [Array.IndexOf (4)] = 8;

  trace (Array);  traces 2,3,8,5

• "Scaling of epizootic ulcerative syndrome and build the waveform (slna)" and "table of string in string delimited a comma."

  I'm taking a picture of waveforms and the units of the scale accordingly.  I have a picture of the sensitivities that the user can change and do this in my "EUs Scaling" under VI.  I would use just of "LAS scale voltage to EU VI LabView", but the sensitivity of my sensors will vary depending on the way through.  I can't much the back wave of construction. I think I'm scaling of values of y in my sub VI correctly.  The sub VI is inside a loop of acquisition data and after reading MX DAQ.  The sub VI is "Scaling had 32ch".

  In addition, when you use DAQ MX create channel he wants to channel names to a string of nouns that are delimited by commas.  How do I take a string array and comma delimit them into one string?

• Table 2D-strings in the "get/set item property.

• How to create a table with strings active by Boolean button

  Hello.
  I have a problem to create a table and did not find any topic in the forum that could help me solve this problem.
  I need to create a table of alarm.
  In other words, every time an alarm has been triggered (Boolean button), the table shows the time, date and where the alarm has occurred.
  For example, when garage alarm is activated, it will be at table:

  Date / / Time / / Garage / / presence ON

  And so on, when the alarm is activated the room:

  Date / / Time / / room / / presence ON

  If anyone can help, I would appreciate it enough.

  Thank you.

  Giuliano06 wrote:

  So I can show the alarm, but when the button is not selected, it sends the null value (empty string) for the table through the registry to offset.

  Also, when I choose for example the 2 bedrooms, it is moved to another column in the table and not just below the last alarm obtained.

  My VI is attached cases someone might have an idea.

  your constantly questioning the value to your table, ofcoarse, this vi is designed according to the mechanical action of the Boolean switch...

  

• Sort a table of strings [problem]

  Well, im pretty new in the java development and app, I used to make games using AS3 and now I am with my teacher in certain BlackBerry applications.

  The thing is I can't sort an array of string, I looked around and I noticed that I need to make a comparison.

  I want to sort an array of XML that will be used on a drop-down list. How can a comparator and use it?

  Easy PS:go on me, im really new ^^

  Which part of this is a problem with? Looks like things fairly straigh-forward.

  You write a class that implements the comparison. You have two methods to implement, compare() and equals(). Each method is passed two objects. It is the responsibility of your application to prvide the good performance based on the two objects.

  Since your comparator compares strings, you have already integrated routines to compare.

  String.compareTo)

  and

  String.Equals)

  In both cases, you can simply return the value of the construction compared with chains.

  See the javadocs for comparator, String, and SimpleSortingVector

  Work on it a bit and come back with a more specific question.

• Random table and present several elements of the array at the same time

  Hi all

  I figured out how to randomize an array and present the items where the user can scroll through the items one at a time. However, I would like to know how I could go for the presentation of the elements of a random array at the same time. To be concrete, suppose I have a list of three words that is Word 1 and Word 2 Word 3. For each user, I'm looking for present all three words on the screen at the same time, but in a different order. If a person can see it on the screen:

  WORD 1

  WORD 3

  WORD 2

  and someone else could see

  WORD 3

  WORD 2

  WORD 1

  Pointers or guides are appreciated. Thanks for reading.

  You say that you already know how random the table, so I won't go into that. Assume that you already have 3 TextFields on screen and called tf1, tf2 and tf3. You didn't say if you use Classes or script code. I'm not a big fan of code of script in AS3, so I'm not good at writing of examples in there. The example here assumes that the class code. It also assumes

  1. You have ' declare stage instances to automatically "off
  2. TF1, tf2 and tf3 exist in all frames of the timeline of the MC that uses this class.

  public class Words extends MovieClip {
      protected var wordSource:Array;
      public var tf1:TextField;
      public var tf2:TextField;
      public var tf3:TextFiels;

      public function Words() {
            super();
            //init your wordSource array here
  
            //a Vector is like an Array, but you're very sure what type of "thing" is at each index.
            //in this case, it's TextFields.

• Convert a table to a cluster of 4 elements array values 2D 2D double precision, or a table 1 d

  Y at - it an easy way to convert a 2D cluster table (4 elements each including a Boolean value and three numbers dbl) to a table 2D or 1 d of double precision values? I need to store my data in a text file to control a robot, I'm trying.

  Thank you.

  There are 1 million different ways to do it. The best thing to do would be to leave the data exactly as it is and simply use Flatten in XML format (search the palette). It accepts virtually any type of data, including a 2D cluster table as you described. He will spit human readable (although not necessarily nice) text that you can write to a text file. Then, read you data from the file and use Unflatten of XML to do the reverse.

  Or you can use a similar model to flatten your data in a 1 d of double table which you can then unflatten.
