• How to write a function block?

  Hello

  Someone knows how to write a function block with LabVIEW?  Something like those in real time live > function blocks >.

  Thank you very much in advance?

  Assuming you are referring to these specifically...

  http://www.NI.com/white-paper/7339/en/

  .. then the answer is that it is almost impossible to make a new. However, there is really nothing special all that to their topic. They are essentially normal subVIs (which you can learn about the other links) which just happened to have some terminals connected to shared variables. I personally would not normally recommend that anyway. If you could clarify what exactly you are trying to do, it might be possible to give more specific advice.

• How to write a function to estimate the number of rows returned SQL?

  How to write a function to estimate the number of rows returned SQL through SQL Execution Plan?
  My idea is
  Call dbms_sql.parse to create the SQL PLAN, then ask the PLAN for the number of estimated return lines.
  But how to get SQL plan through "id cursor?
  Thank you.

  You can use EXECUTE IMMEDIATE to explain plan statement. About the STATEMENT_ID generation, it could be anything. Even a SYSTIMESTAMP cast as TANK would work.

• How to write a function (for an ex-Flash-dev)

  Hiya,

  I am coming from a Flash/AS 3.0 environment and I'm getting a bit confused trying to write functions in EA.

  I'm quite new to JS and jQuery so that something is similar to actionscript, I'm still finding things a little confusing.

  I'm working on my first project with EA 2014.1.1 and managed to get away with the built in functions to date, but I now need to do something more custom.

  For example, in Flash, I would write a function to a button and it would go in the first frame of the timeline or a class file:

  function nameOfFunction (event) {}

  do things

  };

  Then the button, we would have a script event listener calling the function:

  myButton.addEventListener (MouseEvent.CLICK, nameOfFunction);

  Can someone explain to me how it works in the EA?

  It seems easy to use for the very basic functions, but anything more requires advanced js knowledge!

  I watched a lot of tutorials but they are for older versions of the edge or that they cover only the basic stuff.

  It doesn't seem to be much out there at all.

  Thank you very much

• How to write Save function based on the drop-down list box selection data in app mxml flex4 with as3

  Hi all

  I'm working on the application web flex4 with as3.

  I have a doubt, I've created a mxml it has two text boxes, except the button and a combo box that is has two option as a percentage and the amount.

  my needs are I gave here.

  need 1: when I choose option amount that two text boxes does not have to be editable.when I select text tat box two percentage option will be editable.

  need 2: when I select the percentage in combox option and two text boxes are empty, and then click the button Save-> I want to display warning msg

  need 3: when I select the option amount combox and the two boxes are emptu click the button Save-> I don't want any warning messages.

  How to validate it and how to write backup for this function.

  This is my sample code:

  list box ID = baseAmtPer

  ID TextBox1 = maxCommAmt.text

  ID = baseAmtPer.text text box

  If (((baseAmtPer.editable!=true) & & (maxCommAmt.editable! = true)) & & ((baseAmtPer.text=="") & &(ma xCommAmt.text=="")) |) (baseAmtPer.text == "") | (maxCommAmt.Text=="")) -> This condition not allowing while I'm selecing amount in combo box. How the TWO TEXT BOX WILL BE EMPTY for this problem

  {

  Alert.Show ("enter in all areas", "Information");

  }

  on the other

  {

  some encodings

  }

  Hello

  OK, after reviewing the, I don't think you'll be able to write a function of decryption for him.

  The first thing he does is take the ascii value of each character in the password and converts them into a binary string.  The code it uses is far too complex and can be simplified, but which is not a problem here.

  I've recreated the first step of SQL like this...

  SQL > ed

  A written file afiedt.buf

  1 with chr_val like)

  2. Select level l

  3, dump('password',10,level,1) in the dmp

  4, to_number (substrb (dump('password',10,level,1), instr (dump('password',10,level,1),' ', 1) + 1)) as chr_val

  5, ascii (substr('password',level,1)) as chr_val - equivalent of extraction of useless dump

  6 double

  7. connect by level<=>

  8        )

  9, r (l, b, ch, chr_val, result, vtemp) as

  10 (select l, 0 b, chr (chr_val), chr_val)

  11, cast (null as varchar2 (8)) as a result

  12, chr_val as vtemp

  13 of chr_val

  14 union of all the

  15 select l, b + 1, b, ch, chr_val

  16, to_char (mod(vtemp,2)) | result as a result

  17, trunc(vtemp/2) as vtemp

  18 r

  where the 19 b + 1<=>

  (20) depth search first by l, defined b seq

  21, as)

  22 select l, ch, chr_val, str_to_bit result

  23 r

  where the 24 b = 8

  25 arrested by l, seq

  26            )

  27 select listagg (ch) within the Group (order) as password

  Then he takes this string binary ("bit_vals" in my example) and does the following:

  1. take the first 3 bits of left and to transpose on the right end of the string.

  2 chops the resultant bit string upward into sections of 4 bits (which is known as a 'nibble' inside)

  3. for each bit in the nibble, he treats the bits in binary reverse to normal and gives them a value of 1,2,4 or 8 from left to right for each bit set to 1

  4. for each nibble it adds the value of 1,2,4,8 bits to give a value from 0 to 15

  To show that the use SQL...

  Now, the problem of decryption is that these numbers are concatenated without padding for a fixed number of digits by value, so you don't know if it was

  '12' |' 4'||' 12' |' 9'||' 13'... and so forth as we did it, or whether he was

  '1'||' 2'||' 4'||' 12' |' 9'||' 1'||' 3'... and so on, or any other combination of values from 0 to 15

  There is essentially no information to allow you to divide the string upwards in the correct components to allow the whole process be reversed.

  So, you are out of luck... no chance of decrypting it.

• Create a directory tree: how to call a global function from inside a for loop

  Hello

  I am trying to create a workflow that will create a directory tree in vCenter.

  Concept:

  Basically, I am trying to execute nested for loops for each level of the tree to the caller a global tree.

  Problem:

  The 1st loop for works and creates the file 'Dev '.  The second loop for does not work with error message:

  [19:16:16.219 2013-06-27] [I] building Dev folder

  I think it has to do with JavaScript not being not able to call a global function in a nested object (I'm not a programmer and don't know JavaScript, so don't shoot me on that :)

  Code: (will clean this up once I do work)

  var folderBase is ['Dev', 'DMZ', 'Prod', 'UAT'];.

  for (var i = 0, l = folderBase.length; i < l; i ++) {}

  var rootFolder = parentFolder;

  buildFolderTree (folderBase [i]);

  Create the files folderT1 level

  Hello

  The createFolder() method returns the object VcFolder to the folder just created, for the new file to be used immediately.  Here is how I modified the code:

  Create the files folderBase level
  for (var i = 0; i)
  var newBaseFolder = buildFolderTree (parentFolder, folderBase [i]);
  Create the files folderT1 level
  for (var j = 0; j)
  var newT1Folder = buildFolderTree (newBaseFolder, folderT1 [j]);
  Create the files folderT2 level
  for (var k = 0; k)
  var newT2Folder = buildFolderTree (newT1Folder, folderT2 [k]);
  Create the files folderT3 level
  for (var x = 0; x)
  var newT3Folder = buildFolderTree (newT2Folder, folderT3 [x]);
  Create the files folderT4 level
  for (var y = 0; y)
  var newT4Folder = buildFolderTree (newT3Folder, folderT4 [y]);

• How to write a generic function.

  Hello
  
  Can someone tell me the concept, I have to get hip to in order to write a generic function that will work on any object?
  
  Here is the project: I'll be show 24 graphs, (imported as Bitmaps and BitmapData jpg), and I would like to create a function where onRollover graph would be tween on twice its size, then come back to the original dimensions when the mouse is released. Pretty simple.
  
  I'm OK with everything about the import of jpg files and to implement the action of Tweener. And I think it's good to be a better way to write different functions of RollOver and RollOut for each graph, but I must have been absent that day.
  
  When I use 'this' in the function, it behaves like 'this' is planned: any change! But it's not what I'm shooting.
  
  I expect to write the function ONCE and apply it to all the graphics after that I have addChild-ed them, but I can't figure out how to set the variable (in the function) which refers to some object (Bitmap graphics) is set up to the course.
  
  I declare a public variable or something? And match to what is reversed? No need a step by step tutorial, just of me not to point in the right direction. I'll ask Shupe and Rosser. :)
  
  Oh, uh, Flash CS3, AS3... (I prefer to use the Flash environment because I'm still not enough good for simply create the .as files.)
  
  Thank you!

  Each of your JPGs load as a MovieClip/Sprite. Say mc1, mc2...
  Then set properties for all the clips as below

  MC1.buttonMode = true;
  MC1.mouseChildren = false;
  MC1.addEventListener (MouseEvent.MOUSE_OVER, onMouseOver);
  MC1.addEvenListener (MouseEvent.MOUSE_OUT, onMouseOut);

  function onMouseOver(evnt:MuseEvent)
  {
  new Tween (evnt.target, "x", Regular.easeInOut, evnt.target.x, evnt.target.x * 2, 5, true);

  new Tween (evnt.target, "y", Regular.easeInOut, evnt.target.y, evnt.target.y * 2, 5, true);
  }

  This is what helped?

• In the target FPGA read/write control function?

  Hi people,

  I learn a lot from the sample project FPGA, including how you can easily retrieve and set controls and indicators in an FPGA using the read/write control function running in an RT target.

  However, I can't find a way to do something similar in a FPGA target.  I've been down this road before - that is, trying to move the data in/out a looping VI FPGA (void) to a (parent) FPGA VI - where my memory points to reach what I needed use.

  So I was happy to see the palette FPGA enabled me to drop the control functions to read/write on a FPGA vi target.  But alas there where tons of errors (not compatible son for target, etc.) and I guess now it's not possible.

  So, just to be sure, I'm not missing something, is there something like control functions to read/write to use in an FPGA for read/write in an another FPGA (looped)?

  In addition, why would I be able to read/write on a FPGA vi control functions if they are not supported?  (Sorry for the n00b question)

  Thank you

  You're right that I don't have this knot in my palette.  However, I also do not seem to have a Refnum Occurrence in the palette is in the FPGA (see below), but I need to synchronize several loops of FPGA and added research using the textfield in the VI editor (and if compiles and runs).  So 6 months to Labview and I'm fuzzy on how the palette is restricted

  I don't know what you're trying to prove here. There is no control of refnum in search in your image. Occurrences are available in FPGA, and for control of refnum for one you just right click on a function of the instance and create a control. If you can create a valid thread of a certain type of data, then you can create a control or the indicator for it, regardless of the question to know if this type of control or indicator appears in the palettes. However, the functions that you can use in the block diagram are limited by what is available in the palettes.

  Regarding orders read/write for the FPGA/lights, I'm surprised that the infrastructure developed to allow read/write between RT and FPGA has not mobilized to allow read/write between FPGA and FPGA.  The elements of memory function, but they are less convenient.

  You may have noticed that you cannot compile the individual parts of an FPGA VI and combine them later; This is because when you compile an FPGA VI, all its subVIs are essentially merged to create a single block diagram (with additional logic if one not reentrant Subvi is used in multiple locations, this is why it is not recommended on FPGA). The subVIs no longer exist in the FPGA compiled; reading and writing a control on them would make no sense. If you want similar behavior, use global variables - but understand that global variables store values in FPGA logic resources. Using the elements of memory (or FIFO, which can also store in memory) leaves more fabric available FPGA logic by storing data in resources specially designed for this purpose.

• How to write data in mode intertwined with TDMS C DLL 2.0?

  Hello

  How to write data in mode intertwined with TDMS C DLL 2.0?

  I use DAQmx features in Visual Studio C++ without Measurment Studio.

  This function returns the data in interlaced mode.

  How can I configure the functions of DLL C TDMS to store this data in the tdms files?

  I see that it is not possible with the PDM version 2.0 with 1.0.

  Thank you

  -TDM C Dll is not able to do

  -TDM header writer may be usable for this but is not able to be used for tdms files.

• Globals functional in BT 8.5

  Hi all!

  I've been struggling with making functional overall in LabView 8.5. I am a very new programmer, my job is essentially to learn LV online and check/optimize the code left by a previous programmer. His code uses a large number of local variables, many of which feed subVIs custom, so I was thinking only globals functional can be a good way to improve the code. I read that local variables are something of a no-no, but he uses them to pass specific data between a loop of producer/consumer (with the exception of the data in the queue). However, I had difficulties to enter the functional concepts behind the globals, and when I looked for examples on the forums I found examples of old/new versions that do not work for me. I think some esserntial concept is beyond me.

  So I have three questions if you have time.

  (1) exactly how the globals functional?

  (2) are they possible in LabView 8.5? My company does not update for fear of damaging the code we have.

  (3) globals functional would be faster than local variables?

  Thank you all for your time!

  You have two errors in your VI.  A in the case of writing, the other at the Terminal stop.

  The error in the case of writing is what is causing the cut wire.  You create a segment of wire with two sources (one of the shift register, a control).

  

• How to write a single line instead of the entire port?

  Hello

  I followed the example for writing to the digital line as follows

  int taskHandle;

  given int [8];

  char linename [] = "" dev2/port0 / line0:7 ";"

  DAQmxErrChk (DAQmxCreateTask ("", & taskHandle));

  DAQmxErrChk (DAQmxCreateDOChan (taskHandle, linename, "", DAQmx_Val_ChanPerLine));
  DAQmxErrChk (DAQmxStartTask (taskHandle));
  DAQmxErrChk (DAQmxWriteDigitalU8 (taskHandle, 1, 1, 10.0, DAQmx_Val_GroupByChannel, data, NULL, NULL)); Here the data have 8 digits
   
  Error:
  SetWaitCursor (0);
  If (DAQmxFailed (error)) DAQmxGetExtendedErrorInfo (errBuff, 2048);
  If (taskHandle! = 0)
  {
  DAQmxStopTask (taskHandle);
  DAQmxClearTask (taskHandle);
  }
  If (DAQmxFailed (error)) MessagePopup("DAQmx Error", errBuff);

  The example above shows how to write 8 binary to 8 lines, but how to write only one line? I try the following code, but it does not work

  char linename [] = "dev2/port0/line 2;

  ...

  DAQmxErrChk (DAQmxWriteDigitalU8 (taskHandle, 1, 1, 10.0, DAQmx_Val_GroupByChannel, & data [2], NULL, NULL)); Here the data have 8 digits

  The data format for the DAQmxWriteDigitalLines() function will do exactly what you want.

  The data format for the DAQmxWriteDigitalU8() function is a full port (even if you do not have a value of a harbour full of lines in your task).

• Global functional table uses 2 x initialized space?

  I had a thread going on the reduction of the memory allocation on our LabView RT system located here for reference http://forums.ni.com/ni/board/message?board.id=170&thread.id=413552 .

  I use a global functional / Action engine to add to a U32 table that I'll be back to our FPGA PXI via DMA reads cards.  In order to keep the determinism, for the first time this table through the AE to its maximum size (18Million).  During my debugging process, I decided to run the 'Performance and Memory '.  When I put the number of elements to initialize to 18,000,000 I expect the performance tool to show me that this VI takes over 18 000 000 * 4 bytes = 72Mbyte.  However, after this VI running by clicking on the button instant I see this VI meet twice as many 144Mbyte, extactly!

  Then I ran the tool to 'See the distributions of buffer' and with 'Tables' checked, I see a black dot on the table to initialize primitive and a black point on the passage of the leftmost register.  By clicking on the button "help" in this tool I see it say under the table section "to avoid abuse of global and local variables when working with arrays. Reading of a global or local variable causes LabVIEW to generate a copy of the data. "This must be what happens now, but how am I supposed to store these data with the flexibility of an adverse event and do not have an extra copy floating around?

  Here is the part pertient EI for your reference:

  

  Hello

  When you use the function "Initialize the array", you create an additional table. Use the function "Remodeler Array" reuse the already existing table. See attachment.
