• DLL of LabVIEW with arrays of strings in c ++

  I'm looking to use labview to retrieve a list of gas to a txt file and then transfer this list to gas in a C++ program.

  I thought it would be easier to just list the gas transfer a string array of the DLLs in labview to my C++ program.  However, I am not able to output the list of gas using tables; I am only able to output the pointer, not the chain that makes reference to the needle.  Of course, I have a syntactic problem with my method of output.

  I have no problem out of the list of gas via a simple string.  However, the approach of single string requires multiple calls to the relevant dll.

  My code is based on the labview dll for C++ routines example titled call of Labview DLL in Visual C++ this Passes table manages in reference (http://zone.ni.com/devzone/cda/epd/p/id/1518).

  I am sure that what I'm trying to make is simple enough for an experienced programmer to Labview.  However, my labview, C/C++ and experience is limited.

  Thank you in advance for your help.

  My labview and C code is found in the attached zip file.  However, the basic C code and output resulting are:

  // Call DLL.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include "Array_Multiply.h" #include  #include  #include  #include  #include  using namespace std; int main(int argc, char* argv[]) { TD1Hdl handle_var3; long temp; char stringout[25]; temp=25; handle_var3 = (TD1**)DSNewHandle(sizeof(TD1)); // initialize sizes (*handle_var3)->dimSize = 1; // // Gasstring is a function that outputs a Labview array of strings. // However, I can't make this work. All I am doing is outputting // memory addresses. // Gasstring(&handle_var3); cout << "\n gasstring " << *handle_var3; cout << "\n gasstring " << handle_var3; cout << "\n gasstring " << (*handle_var3)->String[0]; //cout << "\n gasstring " << (*handle_var4)->Numeric[0]); // // Gasstring3 is just a single string. There are no issues outputting // this string. // Gasstring3(stringout,temp); cout << "\n gasstring3 " << stringout; cout << " \n enter in number "; cin >> temp ; return 0; }
  

  The output of my source code is:

  

  I think I understood something :-)

  cost < "\n="" gasstring ="" "=""> < lstrbuf(*(*handle_var3)-=""> String [0]);

  There are some macros useful for LStrHandles in "extcode.h", LStrBuf is one of them.

  It seems that there are no problems with memory management, you did it right.

• 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.

• "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.

• 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?

  

  
  

• Return an array of strings of call library function node

  Hello

  I'm having a few problems getting the following work.

  I have a camera from a manufacturer that came with its own .dll and header files. I'm calling the LabVIEW .dll file (2011). In total, there are about 50 functions, and there is a rest that I can't go to work (probably because I understand enough about the topic to interface with an external code).

  The description of .dll is delivered with the following text:

  #define length

  #define MAX_CONFIGURATIONS

  Prototype: int ConfigListGet (char (& sConfigurations) [MAX_CONFIGURATIONS] [length]);

  and the header file with:

  extern "C" __declspec (dllexport) int RepRateConfigurationListGet (char (& sConfigurations) [MAX_CONFIGURATIONS] [length]);

  The function should return an array of strings to the list of configurations.

  The problem I have is that I can not understand how to return the array of strings for the node of the library function call to LabVIEW. I looked a little on the web and the examples in LabVIEW and I can't find anything specific to return an array of strings in this way, so if anyone can point me in the right direction I would really appreciate it.

  Also, if I click with the right button on the node library function call and click on "File Create.c", I would be able to create the prototype of function even that above? I tried this but no luck. Was the closest I came:

  int32_t RepRateConfigurationListGet (char sConfigurations [], uint8_t MAX_CONFIGURATIONS, uint8_t MAX_LEN);

  Thank you very much in advance for any help!

• String array to strings

  Hi everyone, thank you for your time.

  I recorded in a file of data like this:

  name address telephone e-mail, etc.

  Each field is separated by a tab (\t) delimiter.

  I have read each line of the file with the text file reading and read audit function lines, and then use the index string array, the result is: each while the iteration I can get the full range of text (String), I want to convert this string with fields of tab separated in an array of strings.

  Example:

  input string (name address phone email)

  Output of the elements of the string array: name

  address

  Phone

  E-mail

  Thank you all, I would appreciate any help.

  Get a constant table and create a string array, then you can change your output data type.

• .csv in an array of strings

  Hello

  This is probably a simple problem, but I have a CSV with string values in a column with numbers in another.  For example:

  Volume 6

  Diameter, 5

  But much more of a file.

  I would like to be able to read the first column and reach a just the string array.  I tried to use text file in the spreadsheet string to array in table of Index functions, but I can't seem to get the array of strings to work, as happens with 0 for any text only.

  If someone can point me in the right direction it would be greatly appreciated.

  Thank you!!

• Array of strings of text written in the worksheet in LabView 8.0

  Hello

  I've used LabView 8.5 to perform the next action, but as I am now working on another system I'm currently forced to use LabView 8.0 (Windows XP) and would like to avoid the upgrade to LV8.5 +. However if I can't do the following so I'll have to!

  I am wanting to create a worksheet and I use the 'Write to worksheet File.vi' block in LabView. However, as I want to have included column headers, I build an array of strings using the block 'building the table '. This table is then injected into the entry "1 D data" on the block "write to the worksheet. The format for the spreadsheet block is defined by a string with '%s' to enter the entrance of "Format". In LV8.5, the table connects well, but in LV8.0, when I connect the output of the array of strings to the 1 d data entry, the wire becomes broken. The same happens when I use the 2D data entry.

  If I don't do something wrong, how can I put headers in my spreadsheet file? Is it possible in LV8.0, or should I upgrade?

  Thanks for the help!

  There are also detailed instructions on the block diagram of the writing on a file spreadsheet on how to modify it to write strings. Be sure to save it under a new name and in a new location.

• How to insert values of array of String in BPM

  Hello

  I have defined an array of strings in the business object, created a data object and want to fill/insert values inside. I searched a lot of messages and tried several options but no luck.

  My BO:

  " < xs: Schema targetNamespace = ' http://xmlns.Oracle.com/BPM/bpmobject/TestTypes/SimpleArrayBO "elementFormDefault ="qualified"xmlns =" http://xmlns.Oracle.com/BPM/bpmobject/TestTypes/SimpleArrayBO "" xmlns: XS = " http://www.w3.org/2001/XMLSchema " xmlns:bpmo =" http://xmlns.Oracle.com/BPM/bpmobject/ " > ""

  < xs: SEQUENCE >

  < name XS: ELEMENT = "attr1" nillable = "true" type = "xs: String" maxOccurs = "unbounded" / >

  < / xs: SEQUENCE >

  < / xs: complexType >

  < xs: element name = "SimpleArrayBO" type = "SimpleArrayBOType" / >

  < / xs: Schema >

  Add a script task and tried different ways to fill in the values.

  Basic ['a', 'b'] also fails with the error expected "-result tree fragment" rather than "string".

  How to manually enter the values?

  Thank you

  Chandra

  Because your input is coming from a few strings and not a table, you can just add a Script activity to your process and to define table of your target XSD using XML.

  To do this, you must add a Script to the activity-> in the "Application" tab click on 'Data Associations'-> dragging the "Expression" icon above your target object on the right side (not the table but the table parent)-> open the XPath expression box in the Middle-> click 'XPath Exp' in the drop-down list at the top.

  I used your XSD to create the XML file for the logic below:

  oraext:ParseXml (concat ('))

  http://www.w3.org/2001/XMLSchema-instance '.

  "" xsi: schemaLocation = "http://xmlns.oracle.com/bpm/bpmobject/TestTypes/SimpleArrayBO xsd/mySimpleArray.xsd.

  xmlns ="http://xmlns.oracle.com/bpm/bpmobject/TestTypes/SimpleArrayBO" >. "

  ', bpmn:getDataObject('string1') '

  ', bpmn:getDataObject('string2') '

  '))

  When I 'bpmn:getDataObject('...')', you should rather to insert your data object variables both your process chain.

  Hope it gets you going,

• Validation of array of strings

  Hello

  I was wondering if I can validate an array of IPs (string) within custom validation.  I tried this...

  

  (GetAction("com.csc.library","checkIpArray").call (#esxIpAddresses))? true: "IP address invalid."

  Here is the code for the action, the entrance is a simple array of strings and the return is Boolean.

  model var = new RegExp ("^ ([1-9] |)") [1-9] [0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5]) (-.) () [0-9] | [1-9] [0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])){2} (-.)] () [1-9] | [1-9] [0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-4]))$ ");"]

  for (var i in ipArray) {}
  If (! pattern.test (ipArray [i])) {}
  Returns false;
  }
  }
  Returns true;

  For any help or suggestion would be appreciated.

  Thank you

  Joe

  The vCloud Director plugin comes with a set of actions to validate IP addresses:

  • validateIpRanges
  • validateIps
  • validateIp

  You can reuse these.

• Array of strings for DNS in workflow Clone VM

  The VM Clone with single NIC workflow requires an array of strings as a parameter inut DNS servers. I'm not sure how to pass an array to this parameter. In c#, I have:

  String [] dnsArray = {"10.130.132.109", "10.130.132.108"};

  dns1Attribute.name = pmArray [18] .name;

  dns1Attribute.type = pmArray [18] game;

  dns1Attribute.value = dnsArray;

  attributeArray [18] = dns1Attribute;

  However, c# generates an error 'cannot implicitly convert type() Sting in string' for line 4. I tried passing a single string as attribute value, but it doesn't seem to work either - no value is entered in the workflow when it is running.

  Anyone have any ideas on that. An example of Java would be nice too - I am flexible.

  Thank you!

  Hi geno5150,

  here how to create a table to pass:

  var monTableau = new Array();

  MyArray.push ("10,20,30,40");

  MyArray.push ("192.168.100.254");

  Attr.Value = myArray;

  Attr.Type = "Array";

  AttrArray.push (Attr);

• easier way to sort the array of strings 2D?

  I have an array of strings long 2d, and I would like to sort by the value 2. It originated as:

      public static final String names[][] = {
       {"000000", "Black"},
       {"000080", "Navy Blue"},
       {"0000C8", "Dark Blue"},
       {"0000FF", "Blue"},
          {"000741", "Stratos"},
          ...
       {"FFFFF0", "Ivory"},
       {"FFFFFF", "White"}
      };

  As you can see, they are first sorted by hexadecimal values. It is useful for the part of the application.
  
  There are 1 567 entries. I want to the alphabetize the names of color and place them in a widget from the list. I need to retain the values to hexadecimal color associated with name values. All I can think to do something like:
  
  (1) to a temporary array of strings of length 1 - d
  2) fill loop that adds hexadecimal values in the values of name: temp [i] = new String (names [1] + names [i] [0])
  (3) sort [temporary] with built in the sort of Java
  (4) make a permanent new string, [hexValues] array to hexadecimal values
  (5) copy the last 6 characters of each item to [hexValues]
  (6) to truncate the last 6 characters of each element in [temporary]
  (7) create widget with [temporary] list
  
  Is there a more elegant way? What I really want to do is build an array of int 1 d, with the values that represent locations in alphabetical order of the names. However, I see no integrated whole that would make this kind of indirect type.
  
  - - - - - - - - - -
  Second question - can the bottom of each item in a list widget be a different color? Ideally, the list would display in black or white color name and its value of color as the background. Specifically, I am trying to build the list produced by the JavaScript here:
  
  * http://chir.ag/projects/name-that-color/
  
  and add it to my Java interactive color wheel:
  
  * http://r0k.us/graphics/SIHwheel.html
  
  - - - - - - - - - -
  BTW, I've converted its name this Javascript (ntc.js) color to a native Java class. It is freely distributable, and I have the host here:

  People forget that a 2D array is essentially a table 1 d of paintings.

  colorNames.add(new colorName(ntc.names[1], ntc.names[0]));
  

  The above code attempts to pass arrays as parameters to your Builder, but your Builder expects a String object.
