• flatten channel adds the length of the string

  Hi all

  I flatten a cluster chain help to flatten to string.vi. The cluster contains strings and arrays. The flattened string contains the length of the string that is appended to the string.

  So if I have a cluster with only 1 string and a value = "LabVIEW". the flattened string would be "0007LabVIEW". Flatten channel vi has a Boolean entry "add string or array of size? even if I set the Boolean value false, it always adds the length of the string. Is this a bug?

  I think that if you read the detailed help to flatten it to string function you will see this is not a bug.  That boolean applies only to top-level data, once put you something in a cluster or array, the Paris are open.

• Length of the string, excluding the input character/string

  Long story short, I want to replicate the function of the length of the string , but do not include an input the number of characters in string. For example:

  The input string (search) is 'the

  My first string to test is "the big red dog."

  That would mean a 13 string length.

  My second string is "Jumps over the lazy Fox."

  That would mean a length of 21.

  ' Hello World! ' would return 12.

  'The Lion, the Witch and the wardrobe' would return 26.

  I hope that you can see what I want to achieve. How is this possible?

  Use the search and replace the string to replace your 'exclusive' with an empty string string.  Use the length of the string on the result string.  Make sure that everything is already set to TRUE.

• Lesson1 solutions, length of the string, really a God's solution?

  Hello, I was just looking at the solutions proposed for lesson 1 homework and I came on line 65, ex 2 solution where odd length of the string is calculated this way:

  (s.length () & 1) == 1

  Here, we are a group of users of Java for a long time and we still don't completely understand how it really works.

  Do the bitwise AND operation on the length of the string 1 and audit, seems really strange.

  Either way, I suppose it works somehow but is it really a good solution providing a code which may include only a Ninja of Java for the black belt? If you use it in production which will be able to keep it?

  the pit of my ignorance, I wrote this:

  ! (p.length (% 2) == 0)

  Thank you and have a nice day!

  It's probably again my fault.

  I remember presenting examples of lambda at the beginning I used (I % 2 == 0) to test whether a number has been the same. One of our graphics guys chastises me for using rest (%) instead of bits - and ((i & 1) == 0). In C, the remainder operator is usually compiled to some form of a division operation, which is much slower than a - bit operation and exploitation. (An optimizer may be able to replace i with i 2% & 1 but optimizations in c may be quite subtle). In any case, I started to use at the level of the ILO - and in my examples.

  Then I started getting complaints about the use of the bitwise operators because nobody knew how they worked.

  In any case, in Java, the result is well-defined, as a type int is specified as a 32 bit two complement binary number, so I & 1 will tell you if it's odd or even. The force JIT compiler - reduce i % 2 to i & 1, but when the interpreter is running it will go through the slow lane. As someone said, it's a micro-optimisation anyway.

  A ride is what % is the operator remains , not a modulo operator, while for positive numbers, the result is the same. For negative numbers, the result can be negative! So, be sure to not try for an odd number using i % 2 == 1 because it will fail for an odd, negative number, the result will be-1. Test! = 0, or better still simply use at the level of the ILO - and. Of course, the string length is not a problem because it is still not negative, but the problem may occur in other situations, in particular array of indexation.

• How to get the length of the string a vm?

  Hello

  I'm trying to automate some consolidation of virtual machines and would like to add script. I have over 800 virtual machines manually would not work.

  I would like to

  $allVApps = get-CIVApp

  foreach ($CIVm to ($allVApps |)) Get - CIVM)) {}

  find the number of channels and if greater than 8 consolidate them.

  }

  Someone has this practice? or something else?

  I'm in a cloud environment vSphere 5.5, installed latest powercli.

  Thank you

  Don't know why this does not work for others, but what I posted before work for me.  Here is a more complete version of how get the those of VAPP VM.  There are no doubt more direct ways, but that how I made it so far:

  1. get the VAPP

  $vApp = get-CIvApp-name 'Test-VAPP.

  2. get the VMS of vApp

  $VMs = $vApps.ExtensionData.Children.vm

  3. get the ones for the VM first in the list of $VMs:

  $VMs [0]. VCloudExtension.any.VirtualDisksMaxChainLength

  This last command returns 18 for me which is the "Length of the string" value in the properties of the Virtual Machine to the virtual machine in the vCD UI.

  I hope this helps.

• createTextField setting width based on the length of the string

  I wonder if there is a way to easily calculate how wide to make a textfield you create dynamically with createTextField based on the length of a string that is passed as an argument. In other words, if you know you are going to use the font size, is there a way to know how many pixels you need? Thanks in advance to anyone who can offer assistance.

  have you looked into "TextField.autoSize?

• How to check the length of the string (from viewobject) attribute on jspx?

  Hello
  
  JDEV: 11.1.1.4
  
  I use the component of the carousel, inside, I use the Description attribute to display the content about to carousel,
  Now, I want to display a link as well, whenever the length of the description is longer than 150 characters.
  
  Currently backing bean that I am setting the property chklength to true or false, but the problem, the length is that I need a partial target
  and that's my Carousel component I get updated every time... is possible to check the length in page jspx itself inside the vissible property
  
  This is my code
  

  <af:outputText value="#{item.bindings.Descrip.inputValue}"
                                                           id="ot49"/>
                                             <af:commandImageLink text="more.." id="moreid" shortDesc="click to see more.."

  You can try with # instead of $?

  visible = "#{FN: length (Item.Bindings.descrip.inputValue) > 150} '"

• How to determine the length of the string when the string using LabVIEW MoveBlock pointer dereference

  Hello!

  Calling a DLL that returns a pointer to a structure consisting of a pointer to a string, a 32-bit integer and a pointer to another string.

  I managed to MoveBlock to return a consolidation of these three things, and which works very well.

  But now I need to read the two strings I have pointers to which are not fixed length. MoveBlock has a size of entry, but how to know how long channels are?

  Try this:

  ...\vi.lib\Utility\importsl\GetValueByPointer\GetValueByPointer.XNode

  Wire just a constant string to the Type of entry.  If I remember correctly, the draw of endpoint (assuming that the C strings) will be included.

  Sometimes I have just MoveBlock a byte at a time until I get to a null value or has specified maximum size.

• Length of the string to Oracle error with exec immidiate limit?

  Hi all
  
  I can't run the sp DDL statement as < run immediately d_string >, where length (d_strign) = 8655b (d_string varchar2 (9000)).
  If I cut it at 5400 it works OK, I tried to do as much direct < immediate exec 'create view '. "> and < run immeidate d_string >. Complain for lack of right ")" which has been cut, according to me.
  The entire statement (8655 (b) works OK in the query window.
  
  Is there a limit in this case, I know not 4000 b but I thought that it is for display only, I can't go lower than my 8655b and it should be in the PS, is the ddl to create a complex view.
  I can probably do through intermediate table of TWG or something but I'd rather keep in one piece.
  
  Is this feasible?
  
  help much appreciated.

  The thought is not the best way to determine the error. Prove it is.

  I guess the question is not not from any string bing 'cut', but more to do with a query/DDL generated dynamically missing one ")" somewhere in it.
  Try to use DBMS_OUTPUT. Put_line to display the generated DDL/query and see if it is syntactically correct.

• Length of the string output

  Anyone know how I can the sentances first few a long output text field and then allow people to click on a link to read the full text? I tried to help but may not know... I envsion something like this:

  linking to #textfield.remainingcharacters #.
  
  or something to that effect. You get the idea. Thank you!

  
  #textfield.first50characters # and then a link to [more]
  linking to #textfield.remainingcharacters #.

  
  
  #left(textfield,50) # [more]

• Doc XML to a string fails when the string length is greater than 512 bytes.

  I have been using the following code to write an XML string.  If the resulting string is lower to ~ 512 bytes, the string will be created, if > ~ 512 bytes, the routine does not create the string.  Assuming that the doc contains an XML document:

  Doc CVIXMLDocument = 0;
  HDoc MSXMLObj_IXMLDOMDocument = 0;

  ...

  cvistatus = CVIXMLSaveDocument (doc, 0, "Test1.xml");
  status = CVIXMLGetDocumentActiveXHandle(doc, &hDoc);)

  hRlt = MSXML_IXMLDOMDocumentGetxml (hDoc, & errInfo & strXml);

  The SaveDocument routine still works, the XML file contains the XML, regardless of their size.

  The Getxml routine creates only the XML string in strXml when the length of the string is lower to ~ 512 bytes.

  Does anyone have an idea of the problem?

  Because the string is very long, the ICB debugger cannot display. That's why I was wondering if you were trying to print using put or printf. Because the return value is 0 and the ERRORINFO is also stating the success, I would recheck the chain by printing it to the console or a file.

• Need a bit of help with the string read/write DLL

  I have a DLL that communicates via RS232 with some instruments.

  From 2 numbers (parameter number and a number of processes) the DLL will communicate and extract the values.

  I managed to put in place the DLL to get words, characters, long and floats (single precision).

  Now, it is the documentation that accompanies it for strings:

  

  ReadString asks the DLL to get the data of the instrument, if succesfull I have others on call GetString to get the string memory.

  I have a few questions:

  -The values of her star (*) are pointers; As I understand it that it points to a place of memory where the value is stored, is - that correct?

  -How do I know if I pass the value to the DLL, or read? For example with GetString Im not sure if

  I should pass the length of the string to the DLL or if it is read

  -How to get the character returned in a string; IM assuming I need to find somewhere a byte array.

  Now I can also write strings:

  

  As a matter of f:

  -Should I add NULL at the end of the string, or labview does by default?

  My procedure is now: read the input chain, reduce it to the size of the specified string (this is constant according to the setting of the instrument), converted to a byte array and replace the last element of the array with 0 (Null).

  However, the DLL entry expected a character, that I should get in the DLL?

  They can be pointers or buffers. Which of the two is ambiguous in the syntax of C. However, in your case I suppose that piMsgId and pcLen be a pointer to a unique value and pszDest a string buffer.

  -How do I know if I pass the value to the DLL, or read? For example with GetString Im not sure if

  I should pass the length of the string to the DLL or if it is read

  Description is not really clear however most of the C API require today the length of the allocated buffer at the entrance to make sure that they don't overrun the buffer length. They may or may not change this value before returning to indicate the amount of data they actually informed. The pcLen parameter passed by reference probably indicates that this function does this way.

  -How to get the character returned in a string; IM assuming I need to find somewhere a byte array.

  It is not necessary. You can simply set the parameter to a string and must be passed as a C string pointer. In LabVIEW 8.5 or more you can also configure to resize this string for the number of characters as indicates it a different setting of the library to compose the node (CLN), in this case your pcLen. 8.5 you can use a table to explicitedly initialization function create a table Bbyte of the length needed, convert the byte array to string and pass to the CLN parameter. LabVIEW will return automatically only the part of the string up to the NULL character if a CLN is configured as C string pointer

  Now I can also write strings:

  As a matter of f:

  -Should I add NULL at the end of the string, or labview does by default?

  No! If you configure the parameter is a string, passed as a string pointer C, LabVIEW will do it automatically for you.

  My procedure is now: read the input chain, reduce it to the size of the specified string (this is constant according to the setting of the instrument), converted to a byte array and replace the last element of the array with 0 (Null).

  However, the DLL entry expected a character, that I should get in the DLL?

• Set the string for LabView dll parameter

  Hello

  I created a simple vi LV 2010 (departure vi), which reads the identification of an oscilloscope. Then I take this vi and incorporate it into a dll of LabView. I have test the dll calling LabView (RunFrom dll). Basically, it seems to work, but len and ReadBuffer back empty. It must be in the way I'm configuration configuring the setting for Readbuffer (settings) in the configuration of the dll. I tried several different configurations, but nothing seems to work. Any help is appreciated!

  What is the parameter len?  Normally, you should only set the length of the string, but it seems that you did not do this.  Also, you're passing len by value, and not by reference, so the function is expecting her to be a starter and you will never get return a different value to any value that you provide.

  Do not use a local variable of the ReadBuffer for entry "readbuffer".  You must pass a string initialized long enough to contain the expected quantity of data.  The best way to proceed is to use the array to initialize to create a table of U8, then use the array of bytes to a string.  Set the parameter 'minimum size' to 'len' then run through the length of the string initialized (this is not mandatory but is recommended).  If you need the length obtained output, add another indicator and another parameter to this value.  There might be a way to do it with one by len parameter passing by reference, you need to experiment (it is certainly feasible in C but I don't know if allows him to LabVIEW).
