• Several VI instance will not RUN using invoke node

  Hello

  I need to have multiple instances of the same VI running.

  I created a template of the VI I wan't to call several times.

  The VI is called through reference opened with a reference to the model VI VI.

  Parameters of the instance is passed via the control value.

  The opening and settings has been passed, I use an invoke node to run the VI.

  An error occurs.

  "Error 1000 in node invoke in Template_Call field window.vi.
  Possible reasons:
  LabVIEW: The VI isn't in a State compatible with this operation.
  Name of the method: Run VI
  "Path of the VI: NULL".

  Note! The screw must remain open after that call running independently from each other and that the appellant should not wait until the VI.

  Any ideas what I am doing wrong

  Just unplug input terminal to open VI reference function type specifier.

• Understand the invoke node

  In the past, to create an organization, I create a few screws and then call them from other screws simply by work as a sub VI where I could pass a value and the Sub - VI can return a value. Pretty fundamental things and honestly, very useful.

  However, now I have discovered high school and would like to use in conunction with the other screws to my knowledge, in order to run and to transfer data to and from the VI running in high school, I need to use the invoke node. I'm a little unsure on how to use them properly. It is not real clear on how I can pass data to and from the subpaneled VI.

  For suggestions or explinations any help would be great. Thank you.

  
  

• Initialize controls/indicators: invoke node-local variables Vales. Which is faster?

  Hi all

  I would like to get the opinion of the people. This thought just happened for me while I was reading some materials the other day.

  And I have not found any topic which talks specifically about speed after searching the forum.

  It is faster to initialize your controls/indicators using Invoke node OR write directly to the initial value of your local variables?

  From my experience (not large), I have always used the invoke node to initialize controls or indicators.

  But when I but this question, I did a simple reference point and it seems the local variable approach is faster, especially

  If you have the large number of orders/lights to initialize.

  Am I missing something here? The invoke node running something that writing a value of local variable would not do?

  I thought since you need to set the initial state by default for the node to invoke anyway, why not just write the desired initial value

  your local variables?

  I would appreciate if someone can express his own opinion based on their experience and knowledge.

  Thank you ~ ~

  I may need another Cup of coffee this morning, you are in fact callling the reset by default on each individual control.  My last despises, it is that you use the default method Vals.Reinitialize VI all failing.  It will probably be a bit faster than the method on individual controls.  Still not instant, if.

  Are a few msec is worth to you?  If so and you consider the local path, my advice is to group as many controls as possible into clusters for minimize you headaches.

• Set of geometry invoke node: do not have this method (and why is it red?)

  Hi all

  So I take my first steps with the 3D picture control, and I stumbled over the first hurdle!

  How to create a 'set of geometry' call, node, as shown in this photo? If I have the wiring in the output of the object to create an invoke node I get a standard invoke node with several options, but none related to the geometry.

  Second question: why is the Red node to invoke?

  Finally found the reason:

  Hyo

  Today, I easily solved this problem!

  It was the old bug. Replace the old function of read/write with read/write function is the way to solve this problem!

  Thank you very much.

  I'm sorry for taking your time.

• Run VI Invoke node: VI works, EXE does not work?

  It is LV2009 without patches or updates. I call buffer.vi of static reference with a collection of nodes to invoke to run a VI. I don't have a very good reason for it, but don't want this code on the block diagram. I can't wait to put a lot of effort in this since I can just drag the code on the main scheme and I am sure it will work, but I do not understand why it gives me error 1000: VI not in a State compatible with this operation?

  In the EXE file, when I check the status of the execution of the buffer.vi until I say it runs, sometimes bad. Same code in VI, sometimes slow. I also tried to replace the static VI reference with a reference open VI by using the name of the buffer and received the same error message. I have the buffer VI included in the compilation under always included.

  So I was building an example of project because I didn't post all, boredom was the example ON what EXE has no error. WTF. Then I realized that I had another call from node in the boot sequence. OOPS. I put that in there thinking that the only way it would be mistake was if the VI was running before he called, in this case I wanted an abortion there. It turns out also-error (1044 locked VI) when running in an EXE file, even if this particular node using says he works with the runtime. SO, he tried to abort a VI that was not working. The initial error, 1000, just said not compatible with call node state, did not say that one.

  Yes, sorry for the trouble and thanks for the help. Maybe someday I'll understand the problem that I was led to this, guess who is the fact that I can't debug EXEs. Kind of, I think it has something to do with an XControl I always use it because they always appear as corrupted files just before that the debugger fails. Anyway, thanks again, I'll plug that into the real system and see what else does not work.

• call VB DLLs in one registry LW the dll and use invoke node

  Hello

  How is possible to call Visual basic labview DLLs. I read articles about it, I should do first of all a "open Automation" and "invoke the node."

  How can I tell witch dll will be used for the call? With the registration of regsrv32 or how?

  I downloaded sample application but does not work.

  Problem is solved.

• Writing DAQmx invoke node leads to a runtime error (R6025 - pure virtual function call)

  I have a request in which a Subvi DAQmx writing calls calling node (shift of writing and reading NumChans).

  When I launch LabVIEW and the main VI a first run, everything works fine. When I run a second time, LabVIEW crashes with a runtime to Scripture DAQmx error call node:
  R6025 - pure virtual function call

  The LabVIEW failure log file contains the following lines:
  c:\builds\penguin\labview\branches\Saturn\dev\source\compiler\allocsup.cpp(662): DWarn: dataspace moved running!
  $Id: //labview/branches/Saturn/dev/source/compiler/allocsup.cpp#18 $

  Anyone has any idea how this accident could be avoided?

  Problem solved: we have just removed the line NumChan (read) from the node to invoke and readded it again. Now, it works fine.

• AS3 returns a string of XML nodes as null...

  I am working on a project that calls and search in an XML spreadsheet that looks like this:

      <Searchtext Wordlookup="john smith">
          <location>$1</location>
          <Name>john smith</Name>
      </Searchtext>

  and he keeps going for about 100 people.

  Now, my flash takes these data and allows the user to click on a TextBox filled beforehand with a name (whose e.target.data.text is combined with the XML using @Wordlookup) or type the name of the person (new corresponding content of the text box to @Wordlookup) which translates the location of this person to light upward (MC is named the same as the location for each node). This effect works perfectly well by using this code:

    var result:String = xmldata.Searchtext.(@Wordlookup == inputTxt.text.toLowerCase()).location.toString();  

  Now I want to do the opposite; Click on a location, and the code will be able to match the name of the movieclip to node my xm - light to the top of this location, location and name of the person in the output text box. Only problem with this Flash apparently thinks a knot in my xml is now a variable which is not set (it should return the name associated with the location in my xml). I looked up and down for a solution, but I can't seem to solve it (this is probably simple, and I go facepalm myself) inducing code error is the following:

    var resultz:String = xmldata.Searchtext.(location.text() == e.target.name).Name.toString();

  And the error produced is as follows: ReferenceError: Error #1065: location Variable is not defined.

  You don't know exactly why this is the case, thank you in advance for any help!

  All your nodes have a node location? If this isn't the case, you might be better off using child ('location').

• Error in microsoft Binder invoke node

  Hi all

  I worked at the reading of a column of excel sheet using suggestions in the LabVIEW forum that uses ActiveX over these last two days. But could not further due to the error, I am faced with while using to call the node to open excel workbook and is unable to understand what problem & what could be the solution for the same thing. Could someone help me on even. Attached my shot VI and error screen that I am facing.

  Please let me know if you need other information. Thanks in advance.

• problem to open and cancel a Subvi by invoking the node

  Hello

  I have a Subvi, which is runing in a while loop and it's calculation that finished in a variable time. So I decided to add the abort function to invoke the node. This works perfectly when the Subvi is running by its own but gives an error.

  1000 error to reference open VI
  
  Possible reasons: LabVIEW: The VI isn't in a State compatible with this operation.
  
  

  I found that there is a solution for this in the following link.

  http://digital.NI.com/public.nsf/allkb/790AC75B07D971ED86256C53007BDCE9

  So I added the Vi run invoke node in the main vi and abort VI invoke node in the Subvi

  as in the following excerpt, but I still get the same error. Think you I'm missing?

  

  

  Eureka. I found it.

  It was very simple.

  I just add the stop simulation in the simulation loop if time exceeds certain limits.

  Anyway, thank you guys for helping me.

  See you soon,.

• Invoke the node: export image does not work in sub - VI?

  Windows 7 64 bit

  LabVIEW 9, 32-bit

  bug alert!

  See example attached vi

  The image of export invoke node only work while the Subvi is open, so called as a Subvi and the Subvi is closed this function fails to create an image.

  Using the graphical version express XY, I created an xy chart.  Then created an invoke node to export the image of the xy graph.  When I call this vi as a Subvi, it works, as far as the Subvi remains open.  If I close the Subvi and don't run the main vi, no image is created.

  No explanation why this would be?  LabVIEW 10 has the same problem?

  So the answer is simple, whenever an image is desired from a Subvi always use: invoke the node-> get image, in addition to any collection already implemented code to force labview to update the image

• Return an array of strings of call library function node

  Hello

  I'm having a few problems getting the following work.

  I have a camera from a manufacturer that came with its own .dll and header files. I'm calling the LabVIEW .dll file (2011). In total, there are about 50 functions, and there is a rest that I can't go to work (probably because I understand enough about the topic to interface with an external code).

  The description of .dll is delivered with the following text:

  #define length

  #define MAX_CONFIGURATIONS

  Prototype: int ConfigListGet (char (& sConfigurations) [MAX_CONFIGURATIONS] [length]);

  and the header file with:

  extern "C" __declspec (dllexport) int RepRateConfigurationListGet (char (& sConfigurations) [MAX_CONFIGURATIONS] [length]);

  The function should return an array of strings to the list of configurations.

  The problem I have is that I can not understand how to return the array of strings for the node of the library function call to LabVIEW. I looked a little on the web and the examples in LabVIEW and I can't find anything specific to return an array of strings in this way, so if anyone can point me in the right direction I would really appreciate it.

  Also, if I click with the right button on the node library function call and click on "File Create.c", I would be able to create the prototype of function even that above? I tried this but no luck. Was the closest I came:

  int32_t RepRateConfigurationListGet (char sConfigurations [], uint8_t MAX_CONFIGURATIONS, uint8_t MAX_LEN);

  Thank you very much in advance for any help!
