Calling the external functions (DLL)

• Call the library function does not find the DLL in the directory where are my LLBs

  I'm using LabVIEW 8.6.  I have a set of screws in several LLBs.  All LLBs located in a directory.  Most of my screws is wrappers for the functions in a DLL.  I was told to put my DLL in the directory where are the LLBs, and apparently this is how the previous programmer has worked (using an earlier version of LabView).

  In the configuration of the library call, I've specified .dll without path.  (This is how we want our screws are an API that will integrate other programmers, so I don't know where they put things and I can't use absolute paths).

  When I insert the VIs in LabVIEW, LabVIEW can not find the DLL and wonder of spotted.  It's just that here in the directory with the LLBs and when I double click on it, everything works fine.  However my absolute path to the DLL now appears in the library to call configuration, and we don't want that.

  Does anyone know how to make this work?  I guess the location of the screw (or LLBs, in this case) should be the current directory and thus Windows search there for the DLL.  However, it seems that this is not the case (in the least, in the latest version of LabVIEW).

  Thank you.

  Well someone using your library should not have to dig into your screws and do it all on his own. Instead your library must wrap that and hide disorders it altogether.

  The cluster of error has been added when the dynamic path option has been added. It is not useful hide this error output, so it's always there. As well as the dynamic path, there was the improved error handling added the CLN. One of them is that the level of verification when calling function errors (exception handling) can be specified. I guess that some of these options may generate an error code instead of bring up a dialog box, as they did before and that the output of error code can be useful even in the case of static calls.

  As to what you want to do, I would have long managed that with a DLL that has essentially the same functions as your other wrapper DLLs and an initiliasation function that returns a pointer to a structure of functional distribution based on the actual DLL you want to call. Quite like what an object-oriented function dispatch table is. Then, when your interface initilising you call initialize function and specify the device interface/type that you want to use and after that all other functions take a pointer extra function parameter expedition as the first parameter, in addition to the parameters of the real function. This dispatch function pointer would be just a pointer to a structure that contains the table of function for this interface pointers and the sake of LabVIEW would simply be an integer of size pointer.

  The wrapper function then checks the pointer structure validity send feature and call the actual function with the remaining parameters. It is a C programming and may require a planning and desigining the different interfaces to facilitate this kind of technique of the expedition, but it will certainly pay to long-term and make your library even can be used in previous versions of LabVIEW, so that VB etc. without delicate dynamic loading in the level high, programming environment.

• The 193 Win32 API error. Cannot call the C function: private_load_AgCoreTest

  Hi guys,.

  When I try to run Lightroom, I get the following error messages:

  • Win 32 API error 193 ("(erreur inconnue)" ") when you call: load the getCFunction library
  • Cannot call the C function: private_load_AgCoreTest

  So I can't access my library or to make a new library by importing files.

  I run it on a laptop with Windows 10 64-bit, Nvidia GeForce 850 m GTX and a processor Intel Core i7 with 12 GB of RAM and a 500 GB SSD (Samsung 840 EVO). All with the latest drivers.

  I tried already to unninstall and reinstall the program, all my packages of Visual C++ and the dll. I also already checked my permissions for the folder from catalog and granted full access. I also tried to run Lightroom as administrator.

  None of these solved the problem.

  What should I do?

  According to the notes, they followed the instructions here to fix the problem: error: "unable to start correctly (0Xc000007b)"

• Exception in the external code called by calling the library function node problem

  Hello, I am a complete newbie in LabVIEW and need help. I have run tests of reliability and get this error about 2000 cycles. The code sends the digital output of a cylinder which operates the actuator downwards, he reads a signal of the thing I'm testing. Then there is a signal to then drive the actuator to the top and repeat. After about 2000 cycles, I get the error:

  [LABVIEW: an exception occurred in the external code that is called by a node call library feature.] It might have corrupted the memory of LabViews. Save all work to a new location and restart LabView. VI "Footswitch.vi" was arrested at the node 0 x 0 of the Subvi "DAQmx Start Task.vi 7"]. "

  I created this code without any prior knowledge of LabView, so I know it's not good, but it does not have (somehow). Any help would be greatly appreciated. Thanks in advance. I am also attaching the VI.

  cstemm,

  There are a few obvious errors in the code that must be addressed.  First of all, I'm not sure how your code even survived 2000 cycles, you have a Boolean value enter these while loops:

  

  What happens if you read a false? The curls will be stuck in an infinite loop... as the value read from the tunnel will never change, and the stop condition will always be "false".   I think that what you do... was keep reading the numerical value until it is true, so it's what needs to be in a while loop.

  Now, the problem you are experiencing is most likely a result of mass overload of start/stop tasks.  For these digital readings, simply start the task once and stop the task once. Run the start task until your main loop work... reference col in the task and read when you want to. Then, when the main loop is completed, go to this thread of task outside the while loop to clear tasks and stop.

  Programming paradigm is generally (there are exceptions):

  Initialize (startup tasks, the initial set of controls, etc.) -> the main loop (here, most of the code is readings/writings/calculations)-> References(stop tasks, clear data, close any open file references) close

  You don't do any reads buffered of digital lines, so no need to ever stop or restart the task, it gives you just a value whenever you call playback vi.

• Flash cannot call the javascript function in the local html file

  Hello!

  Us is to develop our first application on Playbook. It is an html file including a flash file and javascript code. Everything is packed in. in the file bar, a config.xml file and has been correctly loaded into the Playbook. Everything works locally (no web access)

  Everything works well except when we use an ExternalInterface.call("saveglobalscore",score) in flash that calls a javascript function in the .html file.

  In the actionscript3, we selected the "authorized local file access" and put the 'Security.allowDomain("*) '.

  Any ideas? Thank you!

  External interface tries to access the files packaged locally is currently a known issue.  I have not really of a calendar when or if this can be resolved.  It may be in the code base of flash.

• Error when you try to call the Javascript function in the ActiveX Web browser

  I have a requirement to call a Javascript function in a web page that is displayed in the browser's ActiveX control.  I have the control on the front panel, and I use the Navigate method to call to the top of the appropriate page.  Based on an example, I found, I'm trying to get a reference to the HTML Document so that I can then get a reference to the Fenetreparent.  There is a method of the HTML Window object called execScript who I'm calling.  See the attached image of the code (reference close calls do not appear, but when I run it, they are there).

  I can't the node property that returns the parentWindow reference.  The error I get is the following.

  Error-2147467262 LabVIEW: (Hex 0 x 80004002) No. taken such interface supported.

  Any ideas on where to go from here?

  

  Hello

  I have reproduced the issue and the error you are seen and tried to understand what is the solution.

  It seems that the problem is with getting the pointer to the parentWindow.  From what I read on MSDN, it's maybe a limitation in the use of an ActiveX control in LabVIEW. It seems like Internet Explorer creates the object of the window, and so opening in one ActiveX control you free access to this top-level object.

  Here could be workaround for javascript execution in your program:

  

  I would like to know if it works for you and if it will work in your program.

• Call the javascript function using parameters cause run an immediate dependant

  Hello.
  
  I saw a strange behavior, if I try to use javascript parameters in the method af:clientListener property.
  
  Using the syntax

   <af:commandButton text="Init" id="cb1"
     partialSubmit="true">
     <af:clientListener method="OnInitControl1" type="click"/>
  </af:commandButton>

  and javascript

  function OnInitControl1() {
    alert('OnInitControl1 called');
  }

  the method oninitcontrol1 is called first with the click of the button.
  
  But with the syntax

  <af:commandButton text="Init" id="cb1"
     partialSubmit="true">
     <af:clientListener method="InitCtrl('Control1')" type="click"/>
  </af:commandButton>

  and javascript

  function InitCtrl(frameName) {
    alert('InitCtrl(' + frameName + ') called');
  }

  the InitCtrl function is called immediately to the loading of the page.
  
  In both cases, the javascript file is inserted into the use of af: document

  <af:resource type="javascript" source="/ScriptHelper.js"/>

  Is my "method" of the af property syntax: clientListener the problem?
  
  Paul.

  Paul,

  I don't know if you can call javascript with parameters in the way that you are currently using. However, have you tried using an af:clientAttribute and enhance the javascript?

  Check the operating instructions by Frank on the related topic.

  Thanks in advance

  Hello

  Go to the page template and scroll the tab Standard attributes. In my current theme which has a line that looks like this...

  #TAB_LABEL##TAB_INLINE_EDIT#
  

  You could change this

  #TAB_LABEL##TAB_INLINE_EDIT#
  

  Or make reference to a function that you included in the header.

  Alternatively, you can make the same change to no current tab.

  Is that what you mean?

  See you soon
