  It works, but how to do using regular expressions.

  In fact, I am creating an index of feature based on the skin of a String in order to join other table instead of using as a condition.

  Kind regards

  efends

  Here's a way to do this with regular expressions:

  SELECT Serial_number

  REGEXP_SUBSTR (Serial_number

  , CASE REGEXP_COUNT (Serial_number, '-')

  WHEN '(.*) THEN 0'

  WHEN 1 '(.*) CAN -"

  ELSE "-([^-]*)"-

  END

  1

  1

  NULL

  1

  ) AS the core

  OF the machine

  ORDER BY Serial_number

  ;

  However, if it's a good idea to this part of the index, why isn't a good idea to store the serial number in 3 columns separated all along?  Database are designed to work with (at most) 1 piece of information in each column of each row.  Looks like you got a variable number (1, 2 or 3) of items all crammed together in 1 chain.

• How convert the string in enum by using LabVIEW 7.0

  I learned LabVIEW 8.6, but here at work, so we must use the Solaris workstations built in 95, the more advanced version of LV they will work is version 7.0.  On LV8.6, it was very to change a string to an enum using the format 'text' vi.  On LV7.0, is not available.  I made my own conversion from type vi with a structure of the case, but this is very annoying, because every time I add an element to the enum, I must add something to this vi.  I added the verification code so there is a warning if I add to the enum, but don't forget to update of the conversion of the vi errors.  Is it possible to reproduce the "text format" vi, using LV7.0?

  

  The analysis of primitive string will do the job in LV7.0.  Its a darn good idea to create a control of the enum type-def you use! If the constant and the witness are instances of your type definition, when you change the control (add, delete, rename, swap values) you can press the button to change to apply and PRESTO all your commands, constants and indicators that use the def type are updated with new info.

• How let labview to check the string is in Scientific Notation.

  Hey all,.

  I want to labview to convert a worksheet string in a table. It's easy using the tool 'chain of worksheet to the table '. The only problem I have is that I get the string from a RS232 device and the critical moment arrives.

  Example:

  If I read the data from the buffer it gives me:

  1.50337800E + 00 + 1.70316300E + 00 for both channels, it is converted and accepted

  If there is a slight delay, I get:

  + 1.50337800E + 00 + 1.70316

  It is also accepted because + 1.70316 is also recognized as a number.

  How can program labview to check each number he reads is according to Scientific Notation?

  Thank you

  This regex seems to work for me, for all cases, I've tried:

  [+/-]\d+\.\d+[Ee][+/-]\d+

  Note that it is very restrictive and only follows the shape of ±n.nnnE±mm

• How to convert the string with numbers in the table of Boolean 2D

  Hello

  I have input a string with comma separated numbers 1,192 (starting at 1).

  This string must be converted to a table 2D-boolean. Each number that appears should be true, not true rest.

  The 2D table consists of 4 times of 0.47 Boolean values.

  1.48--> [0.47] numbers [0]
  49.96--> [0.47] numbers [1]
  Numbers 97.144--> [0.47] [2]
  145.192--> [0.47] numbers [3]

  If a '1, 49, 97 145' input string put all [0] [0.3] true.

  How can it be easy/fast resolved?

  Thanks for help

  Break the string of numbers in a table of numbers.  (Spreasheet String to Array).

  In a loop For, index with each issue of this table.  Use in the range and Coerce to see if it is in the range of numbers.  (You can put this in a loop For as auto good indexing through the ranges).  If it's in the range, then use subset replace table to activate the corresponding item in a real.  If this is not the case, do nothing.  Maintain the table of Boolean in a shift register.

  Repeat this step for each number in your table.

• How to convert numbers to the string with an optimal number of numbers?

  Hello.

  I'm doing something that seems just, and I wonder how much trouble I have with this.  I'm sure there is a way to get LabVIEW for this.

  I have a table of numbers (double), and I use the 'Worksheet picture String' function to generate a string that I can write to a file.

  The problem I have is I want to make the chain to omit useless zeros after the decimal point, but I don't want to limit the accuracy of the numbers that requires it.

  For example, if my data is as follows:

  0.02

  0.4476

  -0.0244570001

  I would like for the string I can be exactly like what I wrote above.  However, depeding on the format string that I use, that's what I get:

  format string: %.10f

  0.0200000000

  0.4476000000

  -0.0244570001

  format string: %f (it seems that by default 6 figures)

  0.020000

  0.447600

  -0.024457

  format string: %.4f

  0,0200

  0.4476

  -0.0244<= all="" trailing="" digits="" for="" this="" number="" have="" been="">

  Anyone know what the format string should be to get the string I want to (what is this

  0.02

  0.4476

  -0.0244570001

  Thanks in advance,

• How to get the string (specified by row and column) of txt file with labview

  Hello world

  How to get the string (specified by row and column) of txt file with labview

  THX

  As far as I know, a text file has no column.  Be more specific.  Do you mean something like the 5th word on line 4, where the words are separated by a space, and lines are separated by a newline character?  You can read from the spreadsheet String function and set the delimiter to a space.  This will produce a 2D channels table.  Then use the table to index and give the line number and column number.

• How to save the string in a file with some special characters

  Hello

  I m using MD5 - llb to create a password.

  So, I want to save this MD5-string to a file and read it later abd compared again.

  Works perfectly with a proplem:

  Some Word create a '\r' in the string of MD5 and when I save this string in a file and read it at the time its read as a '\n' for the comparison does not work.

  My question is: How can I record a string exactly as if it were somewhere and read back (also the invisible characters)

  For example, the word: heinz

  is in MD5: \r\FB^\07\A6\07T\C7\D9\C2\94\AB\C9\1DS\95 (string as display codes indicator)

  When I save the string in a file, then I rerad back: \n\FB^\07\A6\07T\C7\D9\C2\94\AB\C9\1DS\95

  I used the "write text file" and "read text file".

  What should I use to record and play back the same thing?

• How to use the string as a terminal window control

  Hi all

  I am setting up a terminal window in my VI and to do this I have a control of the chain and an indicator of the chain.

  I want the user to be able to write a command in the terminal and when hitting enter into the control must update, but not before! I'd do it

  as the user to be able to enter several commands without having to re - click the control with the mouse, so he must stay in the

  control window.

  The result of this chain control is introduced to an external motor controller, which responds with a string entry in the string of an invoke node indicator.

  I tried to make some case of the event, but not quite sure how I'm going to only detect the input control.

  Any ideas how to precede?

  Thank you

  Concerning

  Tommy

  Yes, in the structure of your event, look for an event of your control chain called 'key' down... on the left, there are several upcoming parameters (char, Vcle etc.) where you can use for example the char find char = 13 (back).

  Look here: http://zone.ni.com/reference/en-XX/help/371361B-01/lvprop/control_key_down/

• How to search for a location number anywhere in the string

  I am looking for a string to a number (integer or float) without knowing its index in the string and to extract it - whether in digital format or a string.  for example "52,63 number appears in this string." I want to extract/identify "52,63.

  The functions I've met seem to expect the index to be known or number to be at index 0.  How can I achieve this?

  Best regards.
