  Hi John,.

  It is an error message from the web server providing this site. Specifically, it is something wrong with their PHP code.

  It is not browser specific and would go into another browser besides Firefox.

• Two parallel executions, calling a DLL function

  Hello

  Since this test takes about 6 hours to test my USE, I plan to use the parallel model to test 2 UUT at the same time in parallel.

  I implement the test code as a DLL of CVI.

  However, to my surprise, it seems that the steps that call a DLL function actually traveled in one series, not in parallel:

  Test 2 power outlets if one enters and executes a DLL works, the other waits for the first to complete its operation and return. While the other runs on the same copy of the DLL, so that the DLL global variables are actually shared between executions.

  So if a DLL will take 5 minutes to complete, two executions in the running at the same time take 10 minutes. This isn't a running in parallel in every way.

  What I want and expect also TestStand, was to completely isolate the copies of these two executions DLL such as test two casings could run at the same time the same DLL function by arbitrary executiong their copy of the function, completely isolated from one another.

  So they separated globals, discussions, etc., and two parallel jacks take 5 minutes to run a step, instead of 10.

  Such a scenario is possible?

  If not, how can I use my test in parallel (in truly parallel) when the use of 2-socket test?

  (1) Yes, he'll call the multiple executions in TestStand calling into the same dll in memory the same copy of this DLL. Thus dll called in this way must be thread-safe (that is written in a way that is safe for multiple threads running the code at the same time). This means usually avoiding the use of global variables among other things. Instead, you can store the thread shows in local variables within your sequence and pass it in the dll as a parameter as needed. Keep in mind all the DLLs your dll calls must also be thread-safe or you need to synchronize calls in other DLLs with locks or other synchronization primitives.

  1 (b) even if your dll are not thread-safe, you might still be able to get some benefits from parallel execution using the type of automatic planning step and split your sequence in independent sections, which can be performed in an order any. What it will do is allow you to run Test a socket A and B Test to another socket in parallel, and then once they are then perhaps test B will take place on one and test one run on the other. In this way, as long as each test is independent of the other you can safely run them in parallel at the same time even if it is not possible to run the same test in parallel at the same time (that is, if you can not run test on two Sockets at the same time, you might still be able to get an advantage of parallelism by running the Test B in one take during the tests in the other. See the online help for the type of step in autoscheduling for more details).

  (2) taken executions (and all executions of TestStand really) are threads separated within the same process. Since they are in the same process, the global variables in the dll are essentially shared between them. TestStand Station globals are also shared between them. TestStand Globals file, however, are not shared between runs (each run gets its own copy) unless you enable the setting in the movie file properties dialog box.

  (3) course, using index as a way to distinguish data access are perfectly valid. Just be careful that what each thread does not affect data that other threads have access. For example, if you have a global network with 2 elements, one for each grip test, you can use safely the decision-making of index in the table and in this way are not sharing data between threads even if you use a global variable, but the table should be made from the outset before start running threads , or it must be synchronized in some way, otherwise it is possible to have a thread tries to access the data, while the other thread is created. Basically, you need to make sure that if you use global data which the creation/deletion, modification and access in a thread does not affect the global data that the other thread use anyway in or we must protect these creation/deletion, modification and access to global data with locks, mutex or critical sections.

• 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.

• How to use the node to call a library function to convert C++ source codes

  Hi all

  There are two dll name 'QMSL_WLAN_Transport.dll' and 'QCAMSL_MSVC10R.dll' and some codes c ++ to connect to the DUT. The two DLLs work together for communicaite with the DUT.

  I am confused as how to use the node to call a library function to load the 'QCAMSL_MSVC10R.dll' function as

  g_hResourceContext = QLIB_ConnectServer_UserDefinedTransport((HANDLE) USER_HANDLE,
  UserDefinedSend,
  UserDefinedReceive,
  UserDefinedFlushTxRx,
  true,
  true);
  

  It seems that 'UserDefinedReceive, UserDefinedSend, UserDefinedFlushTxRx' Processaddress?  And "UserDefinedReceive, UserDefinedSend, UserDefinedFlushTxRx"'s functions in 'QMSL_WLAN_Transport.dll '.

  UserDefinedReceive = (_UserDefinedReceive)GetProcAddress(hUDT,"UserDefinedReceive");
  UserDefinedSend = (_UserDefinedSend)GetProcAddress(hUDT,"UserDefinedSend");
  UserDefinedFlushTxRx = (_UserDefinedFlushTxRx)GetProcAddress(hUDT,"UserDefinedFlushTxRx");
  

  Attached DLLs and C++ code snippets.

  Need help.

  Thank you.

  These parameters are reminders - pointers to functions that are called by the DLL - and there is no way to duplicate this purely in LabVIEW. Search this forum for the word "recall" and you will find similar questions (for other DLLs). You will need to write your own DLL (in C, C++, etc.) that implements these functions and provides a way to transfer data to LabVIEW.

• How to call a DLL function that has need of an array initialized structures which can be written in by the DLL?

  I need to call the following function in a C DLL:

  __declspec (dllexport) int MSIL_EnumSpectrometers (SPECTROMETER_ID * spectrometers);

  where the only parameter is a pointer to:

  typedef struct
  {
  tank model [32];
  series char [32];
  Channel int;
  } SPECTROMETER_ID;

  Before LabVIEW 2011 I would use a CIN allocate the memory and call the function, but in LabVIEW 2011, the INC has been deleted and I have to use a library function node call instead. When I go to set the parameter, it seems that I need to set the type to "Adapt to the Type" and data for 'Pointer to data in table' Format, then pass an initialized array of SPECTROMETER_ID with the many elements he so the DLL can fill the table with data. (See the attached picture.) When I do that, however, it blocks LabVIEW desktop.  I guess it is because the DLL is corrupting the memory space of LabVIEW, but I don't see why, because I'm basically passing in a void pointer to an array initialized in the right size. Note that the first node of NSI returns the number of elements required in the table.  Anyone have any idea what I'm doing wrong here?

  In LabVIEW, when a table is in a cluster - cluster don't detain actually table but sort of a pointer that points to the table. If you need the cluster to contain 32 to 32 Add to the cluster. See the VI attached to how it's supposed to be done.

• 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.

• How to read / write to a HID device with call a library function?

  I had tons of problems to read from a device USB HID in VISA. I had no problem make a driver for him and write it in LabVIEW. However, whenever I try to read using Read Visa, Visa USB Control In or interrupt USB event get different types of error messages.

  I decided to give up this route and talk to the device through hid.dll, setupapi.dll and any other .dll that I need to use. The problem is that I'm not sure I correctly use the nodes to call a library function... I've seen several KB articles that explain how to set up the nodes call library feature, but I need more information. I can configure stuff and sometimes get things to work, but I don't always know what each specific selections in Settings tab is doing. Can someone give me more detailed information on what do the settings tab and all of its components?

  Thank you

• 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.

• How to call stunts c ++ function from javascript

  Hello

  Is it possible to call stunts c ++ functions of javascript cascading bb10 without use of qml files. This is a very important part of my application.

  Where runs JavaScript code?

  If it is in Web mode, then the docs document something where you can call "navigator.cascades.postMessage ()" JavaScript and the other side (which could be C++) watch the messageReceived() signal.

  If this isn't in a WebView, where is it if not in QML?

• running personalized script called just a function?

  Work on fixing someone else Adobe forms.  "On the validation tab, they have (run a custom script val) checked, but then it just says" YesNoV (event); "in the editor.   This call to a function from somewhere's else?  I googled adobe thought YesNoV (event) has its own library of JavaScript we can use, but can not find any library.  A fact the creator of this form do not create this form accurately?  I understand it if there were some conditional code in the editor, but don't know what the event is trying to do.  We guess just capture if the user says y or N?

  Guess I'm trying to find out what is supposed to happen if the user selects N or, if something is supposed to happen.   otherwise I can disable the validation, because it does not work properly anyway.

  I know little of JavaScript, but new for use with the Adobe forms.  (just enough to be dangerous, but not enough to accomplish whatever it is) lol.

  Thanks in advance,

  Jim

  Adobe Acrobat Pro DC, Windows.

  Is not in fact a function provided Adobe but a custom function added to the document JavaScripts section. May be easier to edit here.

  You say that you don't see any code for what he does, but you have published, in its entirety:

  function YesNoV (event) {if (event.value! = null) event.value = event.value.toUpperCase (); if (event.value! = "Y" & event.change! = "N") event.rc = false ;};}

  We will write with the best layout

  function YesNoV (event)

  {

  If (event.value! = null) event.value = event.value.toUpperCase ();

  If (event.value! = "Y" & event.change! = "N") event.rc = false;

  };

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

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

  • 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?

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

  Hello

  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:
