• Array of strings 1 d out of MathScript node

  I use arrays of cells inside a MathScript node and want to display an array of strings D 1.  I can't get output with this data type by selecting a column of string elements.  He seems to treat the strings as arrays of characters that are extremely difficult to work with.

  I've seen references 2008 who say that MathScript nodes cannot not out of arrays of strings,

  Is this always true?  Is there an example of how to get a string or some kind of workaround?

  My boss came up with a way to do it, as shown in the attached VI.

• An array of strings as function parameter in loop fails

  Hallo,

  I have a weird problem here and I hope someone can help me find the cause.

  I have a function where I said an array of strings (string_list). I pass the array to a function that does modifactions to the table. I am addressing Walker the array of strings to an index of all the values are stored correctly. When I loop through the array by incrementing the index automatically only the last index value are saved in all positions.

  Why is this? Or what I am doing wrong?

  It is the passage to another function, an array of strings
  
  int calling_function
  
  {
  
        char * string_list [MAX_PATHNAME_LEN];  //< store="" strings="" in="">
  
        function_called (string_list);  passing a pointer to an array of string
  
        return 0;
  
  }
  
  This is the function receives a reference to an array of strings to store data
  
  int function_called (char * output_list [])
  
  {
     int i = 0;  counter variable
  
     / * This works and good values are stored in output_list * /.
  
      output_list [0] = '02 ";
  
      output_list [1] = '12 ';
  
      output_list [2] = "22";
  
      output_list [3] = "32";
  
      output_list [4] = '42 ';
  
      output_list [5] = "52";
  
      output_list [6] = '622 ';
  
      output_list [7] = "72".
  / * This does not work and will store '31' in all places of the matrix * /.
  
      < 32="">
  
      {
  
          < %d »,="" i) ;="" incrémenter="" la="" valeur="">< br="">
          output_list [i] = sample;  < br="">
          i = i ++ ;                   < br="">
      < br="" >="">

  output_list [0] = '02 "; < br=""> output_list [1] = '12 ';< br="" >="">

  Thanks!

  Hi,.

  When you do

  output_list [i] = sample;

  all of the members of the array have the same value: sample-a char pointer. You are modifying the afterwards glad of sample purpose the previous values still point to sample.

  If you assign values to each array member like:

  you assign different values: a pointer to a string containing "02", pointing to a string contaning "12",...
  If you want to assign values in a loop you need to allocate memory for each string (output_list [i]) and copy the content of sample in them.
  Does this make sense to you?

• An array of strings of compensation fileglobal

  I have an array of strings to dimension fileglobal 2. How we it clear whenever the sequence is called, use a loop for? It used to not be a problem, but now seems to have old data in it all the time.

  Thank you

  JVH

  You can get rid of an expression:

  GetArrayBounds (Locals.Array, Locals.OriginalLowerBounds, Locals.OriginalUpperBounds),
  SetArrayBounds (Locals.Array, "[0]", "[]"), / / make the table empty to clear it.
  SetArrayBounds (Locals.Array, Locals.OriginalLowerBounds, Locals.OriginalUpperBounds) / / restore the picture to its original size

  Hope this helps,

• A string in an array of path strings

  Hello

  I want to read in a bunch of paths in the form of a long string such as:

  C:\Files1; C:\Files2; C:\Files3...

  such that when I get it in labview, he will separate this string to the (, store it in an array of strings, and then let me spend some time loop.) What vi can best accomplish this?

  Thank you

  Or simply use the string of worksheet to the array function.

• Convert an array of strings 1 d

  Hello

  I am creating headers in a write to a text file.  Attached, it's my code and the file looks like when opened in Excel. I have my data in three columns, but the headers are not where I need them. LabVIEW does not seem to allow a conversion of an array of strings. Is it possible that I can get the headers in a row format and not a column?

  Thank you

  Something like that.

  

• Property Loader: Array of strings

  I'm looking for an example of use of stage property loader to load an array of type strings labView.

  Not much in the reference manual...

  Thank you

  The best way seems to be to export it first.

  In the variables pane, I created a local array of channels and populated values everything in it.

  Then Tools > import and export properties - Source/Dest tab, set the location of the data to file and traveled in a file name. I used delimited by tabs to Format so I could just type one string per line w / no qoutes. Properties, tab selected table Local, I created. Then click on export and the file was created. Open the file, copied and pasted to other cases and modified accordingly markers.

  Thanks to Chris OR Austin.

• display as an array of array of strings

  Hello

  I have the array of strings to appear as the matrix. Is it possible to use any converter?

  I am using the index table to filter some components and then using build table to combine all the sub-table. now, I want to display in a matrix

  Thank you

  I mean that all the lines and the coulumns should be display on front panel

• "The String to Byte Array" and its operations on-site (memory) of twins "Byte Array to string"? (or if they incur sentence of copy/memory operation?)

  I can't deduct the answer to this question (topic/post title) of the help of LabVIEW on the functions.

  Intuitively, it seems that the two representations of data are equal to the memory and so goes between the two should essentially be a no-op when the code is compiled... but is it? (assuming that the length of the array of strings/remains constant, can I go back repeatedly without performance?)

  As a string of LabVIEW is a handful and any other type of data except tables aren't a handful; that implies to me that a string = U8-table-grip handle and so a string into an array of U8-could be a memory or inefficient operation since no conversion actually take place?

  The reason I ask, is that when you work with for example TCP Read or read VISA, 'data' reading is always a string, but according to what you are doing, this string is often more efficiently processed/interpreted if converted to an array of U8 and I just want to know if (memory and CPU point of view) I can move freely between the chain and U8 array and return depending on what format is most appropriate to a point?

  (Also, I'm at this stage fairly certain that the "array of strings of bytes" is cleaner AND more efficient than a type-cast to an array of U8 strin... but I could be wrong.)

  I did some tests on this just now, and my conclusion is that it is completely in place. The local users group had a coding challenge when this became relevant to my solution.

• Convert the string array to array of numbers

• 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).

• Setting the size of the font of an array of strings programmatically

  I can't find the correct property to programmatically adjust the size of the font of an array of strings.  For a chain, it is quite easy with a property node and the text. FontSize property.  There must be a similar property to an array of strings, but I'm not.  Can anyone help?

  Take the element ref table and class type a more specific (string) and then you can set with a property node's font size.

• by passing the array of strings of Teststand to LV dll

  Hello

  I wonder, why is it not possible to pass an array of strings 1 d of TestStand to a dll, which is compiled with LabView. By the way the PropertyObject works very well, but as parameter category "Array of Strings" exist in the call dll TestStand pane, it should be possible to pass an array directly. I get an empty dialog box, where I try to view the contents of the array passed directly.

  Why it does not work?

  

  
  

• Creating ENUM dynamically string Array

  Hello

  I was wondering if it was possible to create an ENUM dynamically? For example, I would like to read values from an array of strings and use each element to add a new element in the control of the ENUM. If this is not possible, how to set up a structure deal to read values from an array of strings as an ENUM would normally be able to? It would help enormously if I didn't have to manually enter the string name for each particular case. Thank you very much.

  Ditto the comments of Dan.

  If you ask because you want to just save you a lot of work when editing, you could wrie all your channels to a ring and then right-click and choose replace > enum and the object will change to an enum with all the ropes of the ring.

  Be sure to include the case by default since you are dealing with strings.

  I hope this helps,

• Array of strings

  This should be an easy question. I try to use the "write to the spreadsheet" VI from Labview 8.0 but I need to change to accept arrays of strings, rather than arrays of doubles. 8.2 does it automatically, but I'm stuck using 8.0. The instructions in the block diagram of the original VI says:

  "You can change a copy of this VI to accept arrays of strings by changing data 2D and 1 d of channels tables data tables and defining the ├a %s format."

  I'm having a problem changing the tables of data in tables of strings. I looked in 'Properties' for an option and also looked in the 'representation '.

  How can I change the table of control digital channels? Thank you!

  Right-click on digital, then select "replace". Simply browse through the control of the chain on the pallet.
