• String comparisons

  Greetings,

  I am a novice user (stating the obvious here) difficulties with string comparisons. The little attached vi ran an once turned green, but never after that I can't seem to indicate green regardless of entry.

  My ultimate goal will be to determine if a device generates the string "enter user ID: "Chain of true/false game" prefaced by a certain type of channel setting would be an acceptable method?

  Thank you

• Game help String true or false

  Hi all

  I'm relatively new to LabVIEW. I'm using LabVIEW 2013 and I do a communication with ABB robot. I receive the channels of the control of robot in BT via sockets. What I'm trying to do, is if the string 'FALSE', said LV transforms an operator Boolean false, and if the network says 'TRUE', LV passes the Boolean to True. I use the ' True/False Match-String ' function to do this. For some reason, I have problems to do this correctly configured function. This is how I currently:

  Thanks for any help!

  To like to use the 'Game Plan' what comparison of received channels of instruments. In this way is there are spaces before or after (as a stream of return/line), it will always match the REAL deal.

  

• String comparison

  Hello

  I want to compare two strings,

  String1, I read a text file and two string can be a constant.

  After comparing, if the text file string corresponds to the constant, do some processes.

  Someone please comment on this.

  Your question is very basic. PLEASE read the help of LabVIEW and do the tutorials. It is not a waste of time.

  

  To learn more about LabVIEW, it is recommended that you go through the tutorials and look over the material in tutorials the NI Developer Zone Learning Center , which provides links to other materials and other. You can also take a course online for free.

• CAN string comparison to see if I have the right one.

  I am writing a program to test a product that we produce using CAN.  How would I go see if I have a CAN message string to know that our alarm is turned on, on the product?  Is there a way to compare channels incomming and pass it some Boolean value when it does?  Thank you, Fred

  Hi Fred420,

  You can use the simple comparison function to compare two strings. If you have a list of channels, then you can store them in a table and use the search function of table 1 d. Two find a portion of a string in another string, you can use the search and replace function.

  It will be useful.

• Problem with string comparison

  I have a web service that I use two compares two strings, one from the service web xml of my application.

  XML retrieves a string when I compare it like this

  If (xmlVersion == 'true') {}

  }

  It never enter the if condition when I print the value I get from the service I think like this (real).

  So, what's the problem here?

  The way you wrote the comparison. you simply compare the addresses of the two strings.

  Try this instead:

  xmlVersion.equals ("true").

  In fact, you might want to consider getting these out to the back to avoid would be Null Pointer Exceptions, like this:

  If (true".equals (xmlVersion)) {" "}

  Change this

  Select to_char (check_in_date, 'DAY') in the double var_day;

  as

  Select to_char (check_in_date, 'fmDAY') in the double var_day;

  You can use the "fm" (template format) specificaton otherwise the value will be right padded with a space for the size max.

• [String comparison] Shouldn't work but not yet!

  Hello
  == operator should not work with 2 object references, that we do not actually compare the values of the object but just a few addresses? Then look at my code:

  public class Eq{
  
       public static void main(String[] args){
            
                 String a = "hello";
                 String b = a;
                 String c = "hello";
                 String d = "helo";
                 
                 System.out.println((a==b));//true
                 System.out.println((a==c));//true!!
                 System.out.println((a==d));//false
       }
  }

  (1) I assign b reference the same address of a, so it makes sense to get a real for ==.
  (2) I assign c a string with the same value of the strings, I expect == false return because they are different, but... I always get real!
  2 after 3)), I created another string with the value "helo" and I get false.
  
  Thus, == just seems behaves like the method Equals ()... am I missing something?

  Google for "java string literal pool."

• Newbie on string comparison question

  I was messing about with a bit of code and realized that the top operation returns FALSE, then the next operation returns TRUE.
  
  
  String one = new String ('a');
  String b = new String ('a');
  System.out.println (a == b);
  
  
  String s1 = "yes";
  String s2 = "yes";
  System.out.println (s1 == s2)
  
  I expect to return FALSE. What is the difference between the two ways to create a string?

  user558321 wrote:

  It has to do with what we call 'internment of string", which is a slightly advanced topic and you will probably never need to worry.

  Always test for equality of strings with string1.equals("asd") and no operator ==.

• Help String function

  I am trying to edit a snippet of actionscript code and compiling maintains is not after my changes. Sorry I haven't used actionscript much at all.

  Basically, I am trying to identify if a specific character exists in a string and if this is the case, remove this character and all other characters at the end of the string and assign the new string to a variable.

  Here is the code that I wrote which apparently causes the compiler to fail. I'm trying to get 'liveEventName = liveevent' and not ' liveEventName = liveevent? freq = 5'.

  NVAL var = ' liveevent? freq = 5;

  var qMarkPos: int = nval.indexOf("?");

  If (qMarkPos < 0) {}

  liveEventName = nval;

  } else {}

  liveEventName = nval.substring(0,qMarkPos-1);

  }

  Thank you

• Help with comparisons between the work units in the base line

  P6v7 running, I have a base calendar to resources and I want to see the work units of base from the current hourly work units. I go to the spreadsheet of the use of resources and discover real work, budgeted and other units, but I don't have the option to display the basic units. I first thought the budgeted units were the base line reading, but it is not true that the planned duration does not match the unit duration of work budgeted for each particular activity or it corresponds to the duration of the current activity. Don't know what the length of buget reads from.
  
  I found that I can use the activity using profile window to display units of basic work compared to the real and remains as a histogram, but not in a spreadsheet format.
  
  Does anyone know how to check the times of the base line in the format of the worksheet?
  
  Thank you

  user12850365,

  I occasionally use resource and activity of histograms with spreadsheets. After reading your question, I decided to change my own setup and launch a scenario similar to what you're asking and got positive results.

  First of all, I guess a few things...
  * You already have a reference assigned to your project database
  * You are viewing the 'use spreadsheet activity' on the bottom of your screen

  First thing to do is to filter your activities within the project,

  * Group and sort * by 'Total' and show subtotals and totals
  Side to the left of the screen... Display ""BL project Labor units * "and" * budgeted Labor units * "columns on the left side of your screen"
  * To the right of the screen... (The custom Spreadsheet fields) displays budgeted Cum Labor units and Cum BL project Labor
  * My time scale is set to days and weeks

  Adjust your timescale to allow all of your data to display. You will thus limit much of your future data on the screen.

  This should display the two hours provided for in the budget and hours of departure within the spreasheet

  I would like to know if it works for you.

  Hope this helps you
