• Number of bits in a character

  Hi all
  
  Is there a sql function to get the number of bits in a character?
  8-bit characters say, it should return to 8 and 16-bit characters, it must go back to 16.
  
  Maybe that's a stupid question but I need for one of my requirements.
  
  Thank you

  Hello

  You can get the length (in bytes ) of a string using s

  LENGTHB (s)
  

  s may be a single character.

  To get the bit length, multiply by the number of bits per byte or 8:

  8 * LENGTHB (s)
  

• How to get the number of bits of Windows?

  Hi all

  How can I get the number of bits of Windows, the application of the LV is running on?

  By using the disabled conditional structure, I can get the number of bits of the application (if it is built in BT 32 or 64), but not the number of bits of windows.

• Variable number of objects detected in Calculator handling VBAI

  I have an inspection looking for shiny objects (holes) in a product, and in general it is not all (good), but when he does I need to know the location of each hole, to determine the xy-limits of the area of holes, that is, the minutes and culminates each hole xy coordinates. To do this, I would use a stage of caclulator and iterate through all of the holes found... but I don't think that the calculator can handle a variable number of holes... or it can?

  Thank you

  Eric

  Hi Eric,.

  Step of the calculator does not support tables. We have had many requests on the better table support in VBAI and we are going to solve it.

  In the meantime, you can browse the results of a step that produces berries by building a state diagram a bit more complex. Index Example.vbai measures and classify objects Example.vbai for examples on how to do it.

  I hope this helps.

• (number of bits) in a number

  I am decimal to binary conversion and I try to get the number of bits in the binary number called "binary resulting Numer' exit in VI... How can I get?

  #Bits control SETS the number minimum of characters in the string.  The string contains a lot more characters than required to represent the number.

  It sounds as if you are trying to determine the length of the minimum string that displays a binary representation of your number.

  If you use a %b format string and check the length of the output string will display the number of characters in the binary string.  You can also format the control or the indicator to display in binary, assured representation is one of the integer data types.

  With your decimal entry defined for I32, be careful with negative numbers. They all have the same length = 32.

• With a variable number of input ports on a Subvi

  How can I have a Subvi with a variable number of input ports that can be changed in the other VI that uses the Subvi?

  You can't actually do what you trying to do, how LabVIEW is implemented does not screw created by the user with arbitrary entries.  And to be honest, there is probably a better way to do whatever it is you want to do.

  If you really really want to do that, but... you can come kind of close.

  1. create a new VI

  2. change its connector to the one with the inputs and outputs pane more possible (terminals 8-6-6-8, 28)

  3 create controls/indicators for any desired input/output of not scaling can connect the (i.e. the error in / error, son of reference, etc.)

  4. hang them until the connector pane

  5 count how many entries are left and create a control for each entry and their son all

  6 drop your VI on the block diagram of the VI one another as a Subvi

  7. Note that when you mouseover, it looks like a Pincushion

  8. right click the VI and uncheck the "display as icon".

  9. you can now "slide down" at the bottom of the VI

  The terminals in the section "slide down" are as a package by name or node property that you can click on them to reallocate them to what it is not already selected.  The default is to make all the entries in alphabetical order, then all the outputs in alphabetical order.  If you rename the terminals that allows you to make appear in the order that you prefer is up to you.

  As all terminals, for the best that you can do to detect if they are wired is to define a default value that should never be used.  If she is floating points, you can use 'NaN' or 'Inf '.  If this is a cluster that you did, add an item more boolean which is true in the default values for this entry VI.

  Then just wire up all the identical terminals together in a table, filter the items which appear to be unwired and make all your treatment on the rest.

• Extract the Variables from Script Powershell

  Hey guys

  I am building a workflow active directory of this synchronization for the IAC database and I'm looking to make the most effective possible by reducing the amount of powershell scripts I use one only and then use the variables powershell to get what I need.

  Is it possible to extract the variables stored in a variable of workflow instead of use the output of the powershell statement?

  Has anyone built a workflow to users of this synchronization of DB works maximum efficiency on the when modified date now that mine is 28 minutes to synchronize 200 users.

  Matt

  From a design point of view, I would say to use the generic OLEDB data adapter.  There is an OleDB for Active Directory Provider called ADsDSOObject. You can find it by searching on the Microsoft site.  It can be installed as part of the standard Windows or .net.  I'm not sure. If you could get it saved on the server of PO, you would be able to do a select and use the output as native table instead of the Powershell output analysis.

  PowerShell has a tendency to be underperforming.  Certainly, I'd caution against the appellant PowerShell repeatedly in a loop.

• How to check the version of windows and the number of bits?

  Dear Sir

  As I could not download and watch a video show, I was told to check the version of windows and the number of bits. I remembered the upgrade to version 10 of Windows when you are prompted before. However, when I clicked on 'This PC' to check the C:\ drive, it shows Windows8_OS (C :).  It is quite misleading.  Can I know how to check & confirm the correct version of Windows and where to find the number of bits as well?

  Thank you.

  Looks like you're on windows 10, but after the upgrade is not changed the label of the hard drive.

  Type winver in the run box-press windows key + R box simultaneously.

  If the Windows 10 Build 10XXX State, you're on windows 10.

  Simply right click C: / and select Rename and rename the drive in Windows10OS or what you want.

  As far as the pieces is concerned, the PC this right click > properties and see the following line:

  The collections have some counts; scalars don't.

  l_numbers is a collection, so you can see the number of items contained in it like this:

  DECLARE

  List_of_numbers_t TYPE TABLE IS NUMBER;

  l_numbers list_of_numbers_t: =.

  list_of_numbers_t (1,2,3);

  BEGIN

  DBMS_OUTPUT. Put_line (l_numbers. (COUNT);

  END;

  /

  l_numbers (1) , however, is just a scalar NUMBER, you can't use COUNT on it

  In other words, l_numbers (1) is the number 1, so we can not say

  DBMS_OUTPUT. Put_line (l_numbers. (COUNT);

  for exactly the same reason that you can't say

  DBMS_OUTPUT. Put_line (1. (COUNT);

• AM Customer Interface + method with a variable number of parameters

  Hello
  
  I use JDev11 & ADF. I have an App Module exteding, an application custom module (ApplicationModuleImpl) class. I created a few methods and expose them in the Client Interface. I read that I can only use the return types and methods of simple or serialized attributes in the Client Interface of AM. I need to create a method with the variable number and type of parameters, something like "Createwithparams", something like:
  

      public void Method(String[] FieldNames, Object[] FieldValues)

  Is there a way to do it?
  
  TKS.

  You just did it. It should work as far as I know.
  If you can not make available the method try list instead of normal array.

• Generate PrivateKey using byte array

  Hello
  
  I'm working on my school project, where I should simulate the DDA authentication. I placed my public and private keys inside byte [] variables in the applet, and in order to encrypt and decrypt messages I need to convert these arrays of bytes to the PublicKey and PrivateKey objects. I know that javacard.security defines a key factory class keyBuilder, but I can't understand how to use this class, to rebuild my keys, which are in the byte array. Is there a way to do this?
  
  Thank you

  hem. toString? a string? JavaCard know only 8 and 16-bit atomic types and tables. No int. No tank. No java.lang.String.

  How long have you studied javacard?

  the offcard entity will get the keys in arrays of bytes, put them in APDU, send the APDU to the javacard inside the map applet using javax.smartcardio. the javacard applet will then store the buffers received in key forums.

  I think you're mixing offcard code of java and applet javacard "at a distance". There is no magical conduit between java objects and plastic in a card; you need to send APDU commands to the cmdlet to store your keys inside the applet. This means developing a bunch of javacard code that will run in the map, using GlobalPlatform to download the code of the card.

  See here for pointers to base on the map technology.

• Shift of the bits in an array

  Hello

  I am a student in Electromechanics in Belgium and I do a simulation of an explosion with 48 leds for my final project.

  In the attachment, you can see the program that I have already written. I think that this can be done more easily, but I don't know how.

  I cut out 48 leds in 2 tables, with each table 24 LED.

  If you see the program you will understand actually the best way to do this is to shift bits, but I don't know how it can be done in LabVIEW.

  I have to expand my program so it would be nice if I could just let you what to get a better overview.

  So what I would like to know, can I shift "bits" as you can see the leds burning in following VI?

  It must be possible to set the number of bits that are '1' and movement speed.

  3 bits at a time:

  (1) 1110 0000 0000.

  (2) 0111 0000 0000.

  (3) 0011 1000 0000.

  (4) 0001 1100 0000.

  5bits both:

  (1) 1111 1000 0000.

  (2) 0111 1100 0000.

  (3) 0011 1110 0000.

  (4) 0001 1111 0000.

• How to convert a string to byte array

  Hello

  I want to convert a string with a hexadecimal number in the array of bytes, this string includes a cutting-edge information, but I don't want to add this tip to arry bytes.

  detailed information please see the photo. I hope someone can give me some instructions, thank you very much.

  

  The accepted solution of Giedrius.S is not correct, based on the image shown in the first post. That the solution will not eliminate the spaces before the tip, and the string to byte array to convert individual characters '0', '8', 'space', '9', etc. for them to byte values. The right solution, based on the image below:
