Using a reference to an xcontrol in a class

• Bug found during the use of references to the control in subVis on Compact RIO?

  Hallo,

  I have a simple task. I want to read higher VI into a Subvi the real value of a control to a level. I want to solve this problem by using a reference to the control.

  I have attached a simplified program that shows this.

  But the problem is now. When I run the main VI on a cRIO-device, the indicator "DataByReference" is not updated with the actual value. Only when I opened during execution of the "RefMain.vi" too, then everything works fine.

  More strange thing is, when I run the VI of hand on the host PC, everything works well, also without having to open the "RefMain.vi" when executing.

  Someone at - it an explanation for this behavior?

  Thanks in advance!

  This isn't a bug.  See this explanation.

• History of the reset using the reference of table standings

  I want to erase all data of a chart using its reference, but this property is not available. So far the only way to do seems to be using a static property node (the one you are creating click with the right button on the graph by selecting the property you want). Is there another way?

  Because the property node is not strictly typed, the history of the ranking is not available.  If you do the graphic reference of waveform of the wave of chart, the release of the will "of a more specific class' be strictly typed.

• Digital background color works do not when you use the reference

  Hello

  I am trying to use a reference to change the background color of a digital indicator in a Subvi.  The sub - VI strives to change a digital indicator, but when I use a reference to another (reference Numeric.vi) VI, instead of doing all the background, the color I want, only the outline is the color I want, with the rest in white (natural color).    Is there a way to avoid this?

  You must use the NumericText.TextColors.BG property instead.

• Get Null value online by using the reference line.

  Hi guys,.

  I get the null value of the line everytime I use the reference line. Here is my code.

  String rowReference = pageContext.getParameter (OAWebBeanConstants.EVENT_SOURCE_ROW_REFERENCE);

  Line OARow = (OARow) am.findRowByRef (rowReference);

  System.out.println ("row" + Row);

  If (line! = null)

  {

  System.out.println ("Surfing");

  Object succObj = row.getAttribute ("INTERFACE_HEADER_ID");

  String succStr = succObj.toString ();

  throw new OAException ("" + succStr, OAException.INFORMATION);

  }

  Thank you

  I found workaround to get a current line like «($OA.» CURRENT. Id_interface)"as REFERENCE of the LINE does not work. I'm passing the parameter to my Textinputbean in the application of process method and by capturing the current values in the process of request form

  Treat the claim code

  Hashtable params = new Hashtable (1);

  params.put ("param1", pageName);

  Hashtable paramsWithBinds = new Hashtable (1);

  paramsWithBinds.put ("param2", new OADataBoundValueFireActionURL (oamessage, "{$INTERFACE_HEADER_ID}" ""));

  updateIcon.setFireActionForSubmit ("updateRecord", params, paramsWithBinds, false, false);

  Process form Code

  If ('updateRecord".equals (pageContext.getParameter (OAWebBeanConstants.EVENT_PARAM)))

  {

  System.out.println ("after" m "+ pageContext.getParameter ("param2")); / / give you current value as $OA. CURRENT. ID_INTERFACE

• Make the absolute displacement using central reference point

  I want to place a large number of images of varying proportions, using the central reference point at the same point in each page.  I played with the move, and he always seems to use the upper left point.  My reading of the literature suggests that I would get the same results with transformation.

  I realize that I could do the calculations to make the move, but hope I'm missing something and there is a much simpler way to do.

  Thanks in advance

  Jerry

  I finally just did the calculations - it doesn't seem like elegent as moving using the reference of the Center but it works.

  Here is a snippet of the code with the warning that 6.125 and 5.0 are hard-coded and they shouldn't really be OCD made me round up things...

  	XY = myObject.geometricBounds
  	height = xy (2) - xy (0)
  	width = xy (3) - xy (1)
  	x_position = round (6.125 - (width/2), 3)
  	y_position = round (5.0 - (height/2), 3)
  	myObject.move Array (x_position, y_position)

• Using cross-references in the index?

  I was wondering if there are any suggestions out there for using cross-references in the index.
  
  I don't think you use the option 'see also' is what I'm looking for; what I want to do is to create index with a cross next to them reference entries.
  
  I tried this by creating an entry index and typing (see "another name of the topic") next to it, but when I compiled the project that this index entry has not been included because I do not have a subject entrusted to him.
  
  Is it possible to create an index entry of reference without an assignment of subject? Or are there other workaround solutions that you use?

  Index of cross-references are designed to allow you to have keywords in the index when you click on redirect the user to another keyword. For example I use for acronyms to redirect users to the long version. You are subject cross references within the project? If so, you may not use the index of references by indexing the same way? If the cross-reference you want is outside the project, using the index is not the way I would say. Why not use a link in a topic to a URL, file, etc. You may be able to do what you want with a redirection topic, but I haven't looked into this. Come back with more details if I leave the brand.

• Cannot use the references in Subvi cluster (error 1055, invalid references)

  Hello

  I'm going through a lot of that through a cluster to a Subvi.

  The idea here is to manipulate objects in the MainVI in the nodes property thorugh Subvi, which gains the reference number of the cluster.

  In the Subvi, I use unbunling by name to access the references I need. However, I get an error 1055 (invalid references) every time I try to access the object by using the node property.

  What I am doing wrong?

  Attached you will find three files:

  The mainVI: Main.vi

  The Subvi: Single_Cam_RefBased.vi

  The def of the type for the cluster: RefClusterTypeDefinition.ctl

  Thanks in advance,

  Marcel

  The constant you have wired to the bundle is not the same as the cluster of type defined wired to your Subvi.

  I was going to say the same thing. This should be the first thing to try. (I haven't studied the Subvi, but it seems buggy too...)

  COMMENT: Again something is screwed in the current VI which makes no sense. Hovering above the terminal should tell us information about the corecion, but in this case it is said that the terminal is something like a cluster of error. This might just be a cosmetic bug...

  

• Definition of registry FPGA: using the reference transmission

  Question of Labview FPGA basis. When I use FPGA read/write control to set a record in an FPGA, is there a difference between using a FPGA reference 'place' (connection FPGA VI reference Out on a block from the FPGA VI in the next reference) or directly to sharing the same node of reference?  Image below illustrates the two spare connectors: they are functionally identical? If so, why is there an outside reference? Is it just to keep the more neat wiring diagram?

  

  Yes, these two are the same, they would be for any reference type in LabVIEW. The top version is much more clean, however, isn't? Also, if for some reason you do not want to use error wire, wire reference here provides another way to enforce the order of execution.

  Also note that you can drag down the node to read/write to read and write several items in a single node, and they can be a mix of reading and writing.

• How to change the color of the elements of cluster using the reference

  Hello

  I have cluster with 10 LEDS, each LED represents a test within my program, based on success or failure, I want to change the color of each LED, I use the cluster as input reference to test subvi.

  Is there a method to change the color of the induvidual elements?

  Thanks in advance.

  Can be used with any wire Ref properties are determined by the class of the wire Ref itself.

  Generic refs are geneirc properties.

  The FTA to obtain the properties of the elements within the cluster, you will need to tell LV class is a cluster. The same for the items in the cluster.

• Multiple copies of the functional global using vi references

  I have several producers acquisition in a global operation (a functional overall by the producer). These functional overall are identical except for the name. He would work to have only one functional global VI and get a separate reference for each producer? The corresponding consumer would have also used the appropriate reference to consume the data.

  The functional global contains an array of data that must be analyzed by the consumer. It is possible that the data table does not contain a complete set of data on a unique "store" by the producer operation. Of course, the consumer, is written to search for a complete data record before completing the processing of the file.

  No matter that there is a better way, the answer to the question is Yes. The FGV must be reentrant and the reference you open must be re-entrant too and then you can use the CBR node to run the specific copy of the FGV.

  I thought that a reentrant vi would not maintain the State of the shift register not initialized by one call to the other.

  A reentrant VI will maintain the State of its shift uninitialized registers.  However, you must be very careful, how to do this.  You first need to make sure that it is set to allocate Clones.  What will happen in this situation, it is that each different place call you this sub - VI each will be a different clone.  This means that each call will have its own data.  The problem with this is that you cannot share the data between multiple instances and therefore multiple loops.  If you don't believe me, go play with mean it Point by Point VI.

  So what happens if you assign shared clones?  A big freakin mess '.  You will have no control over which clone called where, and there will be a major data corruption.

  This is why FGVs are almost always not reentrant.

• Can I use a reference WITH clause in a JOIN?

  Is the syntactically correct query?

  WITH abc AS

  (

  SELECT a.col1 d,

  e a.col2

  substr(a.Col1,2) f

  FROM table1 a JOIN

  Table 1 b ON a.col1 = b.col1

  WHERE a.col2! = b.col2

  )

  SELECT id, name, date of birth, ssn

  FROM table3 LEFT OUTER JOIN (SELECT DISTINCT abc.d of ABC WHERE abc.f = 'EF') / * Please note the addition of the WHERE clause in the veiw inline * /.

  ON table3.id = abc.d

  I try to use "abc" with a JOIN. Are there restrictions WITH clause?

  Thank you!

  Hello

  user11951344 wrote:

  I apologize I addded the WHERE clause too in mode inline "abcd" (in your query) to understand the purpose. The purpose of doing an OUTER JOIN of "abc" with table3 is to check the "EF" State = abc.f. Please note the Add where clause to update in my original question now.

  I see the changes, but everything in #5 response still applies.  There is no need to make a join in this case.  The output depends entirely on table3.  You will get the same results no matter what, if anything it either, is in table1, so any reference to table1 does that complicate the query and makes probably slower.

• Endnotes in Indesign using cross-references

  Hey all,.

  I'm trying to follow this tutorial using the endnotes in indesign:

  http://blogs.Adobe.com/indesigndocs/2009/03/endnotes_in_indesign_cs4.html

  In what it suggests, what appears in the document ends up being the full note:

  1 Salmerón, Loren The Diet Guide New Jersey: John Wiley & Sons, Inc., 2002, page 56

  so that everything that I want to make is:

  1

  In his case, he could just make "1" appears. I note under reference dialogue format, his example shows "end note paragraph number. There is no option for me. Anyone know what it does I'm not understand?

  Thanks for the reply.

  Looks like this tutorial for step 4 details omitted the details of creating a cross-reference format. Click on the pencil icon indicated by a red circle in the screenshot of the dialog new references to open the cross-reference Formats dialog box, where you can create or edit cross-reference formats. Select the paragraph number in the list of formats provided by InDesign, then click on the '+' to paragraph number in double under the number of paragraph (1). Replace the note at the end of paragraph number name, as in the tutorial, or any name you like. Enable (check) for reference character Style, choose the style of characters superscript, you created as described in step 2.

  The "" notation in the reference format dialog box captures only the part of subsection the reference point to auto-numerotees. In your example above, it is supposed to be "1".

  Google search for terms like "InDesign create cross-reference formats", without the quotes, if you need more information about the several subtasks of reference mentioned here and in the tutorial.

• using the reference find send me modal autoguiding errors

  Hello

  We have an NI PXI-7354 controller not to not/Servo control a player Primatics PN 0-7205-0012 2-axis, 2 rotating turntables Micos DT-120 running.  Recently we know modal errors during autoguiding'-70119 (NIMC_limitSwitchActiveError), move the desired can not be completed, because the entry limit is enabled in the direction of the market. »

  This system has worked for years, a dthi sjust began to appear on homing which occurs once a day.  This happens when the move to find reference goes to the opposite limit, because it is programmed and configured for this purpose.  It then performs a small movement to the front, and then this error occurs.  Now, I understand that this is part of the command search referrer.  It seems as if grace to carry on the switch, or perhaps in the stadium itself when it moves forward to the switch in an attempt to approach of the reverse switch slowly with specific accommodation, that is not actually the switch, and the movement fails.  It is not easy for me to change the switch on the scene, but it can be done.  I wish I could say find reference go further forward, then he actually gets the switch before it he comes again.

  So, I guess that's supposed to happen

  1: the reverse of the race during the domiciliation

  2: switch hits

  3: small forward

  4: move in the opposite direction

  5: Press the switch - success home

  Step 3 moves a pre-programmed amount?  If so how can I change?

  Alternatively, step 3 move until the limit becomes inactive, in which case I'm having bounce or noise on my switch entry.

  I tried to adjust the position of the switch House, there is a small amount of adjustment possible.  I also changed the speed of the stroke finding reference to 50000 c/s 25000 c/s and I have yet to see another failure, but I am not convinced that this is the best and most permanent action plan.

  Any help would be greatly appreciated.

  Have you had a chance to watch http://www.ni.com/product-documentation/4190/en/ ?  Your thoughts sound than the limit switch is always on even after step 3, which must turn off the switch.  Looks like that means to get around this issues is perhaps to change the direction of final approach or the speed of movement.  From this page on the limits to find: http://zone.ni.com/reference/en-XX/help/372134F-01/ni-motion_help/findforwardandreverselimits/ it seems that any direction final approach should work, because in step 3, he should see the switch disable before approaching again, but maybe give changing the final approach response to try.

• History of clear waveform using the reference

  Hello

  I would like to clean up the history of the wave I have in my hand Vi. I'm passing his reference to a sub - VI. I'm not able to find ownership of historical data among the other properties of the property node. Behold that I have:

  

  Thank you.

  -H.

  And I think that your graphic reference is wrong. Have you copied the reference of the hand? In your hand, you have connected a data type? Since it has a variety of data that can be wired, you must do this so the history is the correct data type.

  And what you're trying to do with the True constant wired for all at the end of the Terminal loop? The loop only runs once.
