• event recording refnums data types do not match

  Hi all

  I'm new to LabView and I need help. Here's the situation:

  I am trying to add a user event by using the function 'create a user event '. The output of the function 'create a user event' placed in a control "Event Reg Refnum" (do not know if it is a control), but see diag2.png. But as soon as I add the user, the thread event at the entrance to breaks "event Reg Refnum".

  I think I know sort of what the problem is, as stated in the context-sensitive help, where the 'Reg Refnum event' has only one data type, which is "User event - Quit Application event". The user event that I add, 'Event to end execution', is not in the "event Reg Refnum".

  The question is: how to extend to the Reg Refnum 'event' to include 'Event - event to stop executing user' to solve my problem?

  Can experts out there if you please help me?

  Yours,

  chati

  Hi chati,.

  the fastest way to do this is to cut the connection, create a control on the exit of 'register of events' and add this to the cluster instead of the original refnum.

• Call a PL/SQL stored procedure - data type mismatch

  I call a PL/SQL stored procedure from within a procedure of ODI using the specified technique page Cezar and Julien (http://odiexperts.com/how-to-use-plsql-procedures-and-functions-in-odi) and I get the error "Wrong number or argument types»
  
  I tested each of the types of parameters, in that I'm passing and it is the text that is causing the problem. I tried to use 'Text' and 'Alphanumeric' for the data type of the variable of the ODI and so many VARCHAR2 and VARCHAR for the PL/SQL parameter type and I can't make it work.
  
  Is there a trick for passing a string in the ODI PL/SQl?

  Hello

  Ensure

  1. to declare/refresh of the variable before call to PL/SQL.

  2. If the variable is of "alphanumeric" ODI calling must be attached to apostrophes and prefix with the code project as ' #MYPROJECT. ODI_Var'

  3. as parameters you have u who must pass both during the call (IN, OUT, etc.).

• Get the Data Type of queue

  I'm working my way through my first vi producer consumer and I have two questions.

  1 I am the queue data x, y samples acceleration waveform type z. The code snippet shows how to set the data type in the queue to get. It is rather ugly and disturbing, even if it seems to work.  Is there a way more elegant and beautiful to set the data type?

  2. the sampling frequency of the accelerometer is 5120 Hz.  The DAQmx Read buffer is 1024 length samples.  Therefore, it takes 200 [ms] to fill the buffer.  I put the metronome 100 [MS] to ensure that the producer is not without samples.  This means that the loop While producer will spend much of its time waiting.  Right?  Given the wait cost anything?

  In ProducerConsumerExample.vi of LabVIEW, the sampling frequency is 10000.  The size of the read buffer is 1000.  And the metronome is set to 100 [ms].  The sampling frequency of the device comes from the hardware device in the cDAQ.  100 [ms] interval comes from the PC.  It will not be a mismatch?  I would like to understand this before I put my metronome to 200 [ms].

  It is not spinning as he waits inside the DAQmx Read for samples N must be obtained.  This isn't a request for data.  It takes time to collect these samples.  That length of time depends on your sampling rate and how many samples you request.  So because he is waiting inside the DAQmx Read, there is no need to add an additional wait.  Let the DAQmx Read limit the rate of the loop.

  It's actually like the loop of consumer for the consumer to the producer.  Playback of the queue will limit the rate at which that loop runs.  It should therefore no waiting.

• Creation of Data Type when the script crashes LabVIEW

  When you use the script (LV2010) if I call the Create method of Data Type (available appeal node when a reference to the BD is cable), if I have all but 1 up to the wiring on 'style' terminal, LabVIEW, it blocks. LabVIEW then restarts with an error message saying that "the last time that you have run LabVIEW internal error or accident took place in lvmain.cpp, line 1756. If I have wiring 1 However, it creates a constant fine.

  I see in the context-sensitive help that it always creates a control at the start, but it seems that I can't get it to create a constant. So, okay, I decided to go around, create the constant, take the new object refnum he returned and there to change the constant in one control... but I can't get this work. Can someone point me in the right direction? Here is the code and the screenshot; This is a quick drop plugin.

  It is intended to run on a cluster that is perceived as an icon if you want to test, you need to create that.

  I presented the 'style' value, 0 if if you don't want to plant LabVIEW, set it up to 1.

  

  No time for an in-depth exploration now.  Create from Datatype killed my LV10.  What I was able to do after creating a constant of cluster, the consultation as an icon and select it.  (1) with the scripts, create a new VI and stick that the constant to figure (2) mount the pasted objected to the ClusterConstant and the change of control.

  I think I know where you're going, should be interesting.

• Is it possible to get the data type of element of a queue to itself?

  Hello world

  I have a Q which has a cluster as data type of element.

  now when I want to enqueue

  I will use bundle-default-

  and for this I have to have my current data type

  (long cable as (perhaps after where I got the Q).

  My question is,

  If there is a method/property-node/something that allows me to

  the queue of wire inside Refnum and receive the data element type.

  If I can get into the top of bundle-default?

  (I really want to have this cable in all directions)

  is this the reason why I'm asking here

  aid for the Refnum of outgoing queue to get a queue, the method

  indicates the data type of element and so I hope that there could be a solution.

  thx for your time

  and soon

  j

  Get queue status must be output with the type of data (more precisely an array of the data type and an array of clusters if the data is itself a table). If you do not set the items back to entry to T, this should not even cost anything.

  That said, I agree with others that it is better to what actually a typedef.

• custom RefNum - what is underlying numeric type of refnums and how to respect the subtype

  Specific RefNum, I intend to help is based on the byte stream file refnum - and will have an impact in and out of a DLL through knots of interface code - would it be U32 or I32 underlying type or something else?

  I based the concept of subtype on the following online reference:

  http://labviewwiki.org/RefNum

  Is to correct the above and the way in which the 8-bit values are encoded in the type digital refnum (ESM or other?)

  The subtype is not at stake here, nor do anything in the external code to change. The refnum itself is a MagicCookie (definition extcode.h) and an opaque value that, together with the type of refnum, which is implicit, determines resource for LabVIEW.

  Include extcode.h in your /cintools directory , declare it as MagicCookie or LVRefNum, which is an alias for a MagicCookie. There is no C interface function to work directly with a LVRefNum for a datalog file, or a bytestream file, but for the bytestream file you can use the FRefNumToFD() function to get the underlying file descriptor and then use FM * () functions that use a data type of file to read and write to this file.

• For the complex data type, how to generate the Dll with compatible interface to C/C++

  Hello

  I used the Labview FPGA module to develop test equipment. Now, I need to write a driver that is to be a Dll with compatible interface to C/C++ for this equipment. So that my client who is familiar with C/C++ can call the driver without any study on labview. But I had a few problem on how to convert labview for C/C++ data complex data type. To clearly explain to my question, I have attached a simple example. (see attachment) I try to generate a Dll for the attached example VI and get the the function prototype at the head of the files as below:

  ' void OpenFpgaReference (LStrHandle * RIODevice, TD1 * errorIn, LVRefNum * FPGAVIReferenceOut, TD1 * errorOut).

  As you have known, the type of data "LStrHandle * RIODevice" and "LVRefNum * FPGAVIReferenceOut" Labview data format are. C/C++ do not have this kind of data type and can not reconige it. As a result, I can't call the Dll of C/C++ programming language. How to convert these two data type of labview for the C/C++ compatible data format, and then build the Dll? Anyone know about this?

  The answer is really apprecaited! Thank you in advanced.

  As I found in the following article:

  LVRefNum is the name of resource of LabVIEW VISA or refnum, and "it is impossible to convert LabVIEW VISA name of resource or refnum VISession valid ID."
  This means that external code modules can not access & control the session VISA which is open by labview. But for my purposes, I will not attempt to access this VISA extenal code(C/C++) session. I just hope that save this session VISA in the external code once I opened it in Labview dll; and pass it to the labview dll when needed. While I have not need to login again when I need to control the device. Is it possible to do?

  A LVRefNum is really just a single int32 value. Its meaning is useless for other environments than those who created it so that you Michael not any what in C/C++ caller but pass it back to other functions in your DLL, but this often isn't a problem at all.

  You can take the following statement of the LabVIEW extcode.h headers and add them to your delabviewed header files to make it work in such a way.

  #define Private (T) typedef struct T # _t {void * p ;} * T}

  Private (LVRefNum);

  The LStrHandle you must set a standard C string instead in your export DLL and document what is the size of the string buffer should have if it is an output parameter.

  TD1 error clusters should also be divided into their parameters (C compatible) separate for all items or just to the left of suite entirely.

• Import XML and bad data type

  Hi all!

  I have a form, I want to import xml data.

  In the xml data file: when I put a string in a numeric field (error) and the i value import data in my form:

  Acrobat don't tell me there is an error in 'format', but rather the value 0 (zero) value is put is the field.

  Is there a way (early event) to detect a data format error in the xml file?

  Thank you

  Not that I know of... .He is trying to bind the to imbound field in the form field and if it can you see your data... otherwise it will not appear.

  It is assumed that the incoming data was validated against the schema before importation is made so avoid data type mismatches.

• Calculate w / Numeric or Decimal Data Types

  Working in ASP VBscript, connected to a SQL Server 2000 database.
  
  Trying to average values returned in a Recordset into a session variable, using the following:

  Dim vResp
  Dim vLead
  Dim vQual
  Dim vPack
  Dim vTotal

  vQual = rsQuality.Fields.Item ("Qual"). Value
  vPack = rsQuality.Fields.Item ("Pack"). Value
  % >
  
  < % Session("AVG") = (vComm + vResp + vLead + vQual + vPack)/5.00% >)
  
  It works fine as long as the data type for the columns of the source in the SQL Server database is "Integer", numbers of i.e.whole. When the data type is 'comma' or 'digital', the following error is generated when the page is served:

  Try their casting as Double (CDbl()):

  vComm = CDbl (rsQuality.Fields.Item("Comm"). Value)
  vResp = CDbl (rsQuality.Fields.Item("Resp"). Value)
  vLead = CDbl (rsQuality.Fields.Item("Lead"). Value)
  vQual = CDbl (rsQuality.Fields.Item("Qual"). Value)
  vPack = CDbl (rsQuality.Fields.Item("Pack"). Value)

• Using film as a data type time codes?

  I work in the film, and I was hoping to use numbers to help me create quotes for a VFX project (based on cost per second). I tried to create a custom data type, and it works almost out of an important obstacle. -That, even if he is HOURS: MINUTES: seconds, DURING which it is not no matter what equivalent of FRAMES (which are usually 24, 25 or 30 depending on what video format you are working in).

  I use Adobe Premiere to export a list of lots of files under a CSV file, which are fine numbers. However, manipulate these data is - I would say - impossible without the support of the video time code. Anyone working on a solution for this? Or is there a suggestion feature to me link to forward this to the team of numbers?

  Thank you very much

  You can give your comments and suggestions to the numbers > provide comments numbers in your menu.

  But everything first, perhaps you could post more details of your problem, what your imported data looks like and what result you want.

  If the imported data includes a column for the frames I think you can convert that.  In all cases, the specifics would help.

  Wayne explains how to post a screenshot in this thing.

• Work with the first HP data types?

  I'm trying to get a clear understanding of the data types of HP Premium so that I can better exploit feature internal rather than copy and paste, edit, or having to retype. However, I can't find a tutorial, guide to style "quick start" or comprehensive information on this subject anywhere. Finally, I would like to do things like the following:

  (NOTE: I only list these questions in order to better explain what I'm looking for.) "There ARE no need to answer.)

  • Pass a list of expressions (sometimes solve() returns a list) in a function such as unapply() and run it on each item, rather than interpret the list as parameters
  • Precede the value of formula 1, "Y =" and then save the result in V1
  • Understanding type (x), type (X) and ('X') - I understand that X is a floating point number; x and 'X' they return all two DOM_IDENT, but are in that they also treated the calls function?  Or 'X' becomes X and then treated as a float value?
  • Is there a better way than unapply(), to replace by X-> x to a function, a function of return?
  • For example if: F1 = X-> Sin (x)
  • NOT a function: the seizure of F1 (x) returns the expression: Sin (x)
  • IS a function: unapply entry (F1 (x), x) returns the function: x-> Sin (x)

  Is anyone know if such a guide or tutorial exist, and if so, could you please point me to it?

• Simulink Inport/Outport data types

  I searched for a while and I am unable to find documentation about what types of data I need to use the inports, outport, settings and in my Simulink models.

  Is there some specific types of data that are, or are not supported?  How VeriStand to determine how to coerce data to send the model?  Also, I was under heard VeriStand uses doubles for everything but then I saw a post that says he uses of I64.

  Any clarification would be much appreciated.

  VeriStand 2013 SP1 (probably upgraded to 2016 in next year if it's relevant)

  MATLAB 2010 b and MATLAB 2012 b (currently)

  > Are there types of specific data that are, or are not supported?

  I don't remember there being any limitation of types beyond what is stated in the considerations help document.

  Considerations relating to the integration of The MathWorks, Inc. Simulink® software models (model Interface T...

  The big hiccup I remember wasn't mainly with types of configurations and data bus.

  IIRC, you can choose any numeric type desired in Simulink. The structure of the model interface that uses VeriStand will handle any type and convert it to double so that it can be consumed by the VeriStand engine.

  > How VeriStand to determine how to coerce data to send the model?

  I think the way it works is that when VeriStand interacts with the Simulink model, it gets a list and information (pointer, data type) of inports, remote villages and settings. Thus, it can capture data from the model (because it has the pointer), and it can cast its data type (because he knows the type) duplicate. If you look at the example model model interface on line 212 it might help to make things more clear on how this could work.

  C:\VeriStand\2016\ModelInterface\custom\examples\template.c

  Double USER_GetValueByDataType (void * ptr, int32_t subindex, int32_t type)
  
  {
  
  	switch (type)
  
  	{
  
  		case 0:
  
  		{
  
  			/ * double * /.
  
  			(double) return (((double *) ptr) [subindex]);
  
  		}
  
  		case 1:
  
  		{
  
  			/ * only * /.
  
  			(double) return (((float *) ptr) [subindex]);
  
  		}
  
    	}
  
  / * return NaN, ok for vxworks and pharlap * /.
  
  	uint32_t nan [2] = {0xFFFFFFFF, 0xFFFFFFFF};
  
  	return *(double*) nan;
  
  }

  I'm guessing that the full implementation of which uses VeriStand is much more complex, but I think that the idea is the same.

  > Also, I was under heard VeriStand uses doubles for everything but then I saw a post that says he uses of I64.

  VeriStand engine uses indeed of all double rooms.

  You happen to remember this post and you can share the link? I'd be curious to see where this is said and in what context.
