• How to get the result of the test of CVI DLLs in teststand!

  I write a driver dll to test a source, I want to get the tension of world SERVERS (the instrument of the RS) and I used to call DLLs that written by CVI, teststand

  My question is what is the best way I can get the result of the test and show the user to teststand. the code below is fair? When I used to call this dll document, teststand

  "" I just get the result by setting in TS.this is a good meathod, and what should you do in teststand, I put the "outputVoltageV" point to an object?

  sean_tan,

  Yes, you just pass a value of digital TestStand (e.g.; locals.number).

  If you use the adapter of the ICB, it might make more sense that you can use the Flexible DLL adapter for this type of function, that you do not use the standard settings of tTestData and tTestError. While TestStand will correctly recognize the function prototype, you want to make sure you that include the type library of your function Panel (you will need to create one if you have not already done so) in settings target of LabWindows / CVI-> type library.

  I hope this helps.

• Definition of the parameters of the VI in LabView Action Module with TestStand API

  I started playing with the API, TestStand, and I have questions on how to configure a TSAdp.LabViewModule.

  I use a few examples of NOR and the community of developers to get started:
  http://www.NI.com/example/30263/en/
  https://decibel.NI.com/content/docs/doc-18401

  These examples work as I expect and I understand them.  I am struggling with how to specify VI parameter values in the module when the step type is 'Action '.  In other words, how to set these parameters?

  

  All the examples I see use of step types that have defined fields, which are accessible through the API with 'AsPropertyObject '.  The action type, by default, has the result field.

  Set the values of the parameters of a VI with the API TestSTand?  If so, how?

  Thank you

  Well, I thought about it on my own so I figure I'd share the solution:

  

• Pass a CVI struct containing a type listed in TestStand?

  Hello

  I have a CVI struct that contains an enumerated type.  I want to call a CVI function with this structure as an argument of TestStand.  I created a similar structure (type of container) in TestStand and the other fields of the struct appear to be passed to CVI TestStand ok, but the enum field is always zero.  No idea what I can do?  I don't want to change the CVI enum and struct definitions.

  Example:

  typedef enum {OPTION_A = 0, OPTION_B = 1} eOption Option;

  typedef struct stMyStruct {}

  Double;

  int b;

  Option c;

  } MyStruct;

  Thank you!

  It turns out that my definition of type of container TestStand didn't exactly match the CVI struct, with respect to the sizes of the fields.  Once I fixed the defintion of container TestStand to make the memory of packaging exactly match my CVI struct, enum field passed very well (I defined the field enum as a signed integer of 32 bits in the container TestStand properties).  I didn't need to create a public service or a type for my CVI dll library.

  Thank you!

• Reliablity of the use of the CVI DLLs in testStand

  Hello

  I wrote a file .dll using the ICB and tries to use the functions available in aid TestStand. I get strange errors, not always but when I run TestStand. Here is my code in the dll.

  int GetAverage (double* aBuffer, unsigned int aSize, double* aAverage)
  {
      double total = 0;
      enum t_eErrorCode eErrorCode = 0;
  
      if(aSize <= 0)
      {
          eErrorCode = eARRAY_SIZE_ZERO;
          goto Error;
      }
      for(int i = 0; i < aSize; i++)
          total += aBuffer[i];
      *aAverage = total / (aSize);
  Error:
      return eErrorCode;
  
  }
  

  He sometimes throws only an eError_SIZE_ZERO error, but when I checked in the debugger TestStand, size sent to the function was not a nullity (see attachment).

  What can be the reason or what I am doing wrong?

  Thanks in advance,

• Conversion/appeal of an application created with CVI in Labview

  Hello

  I have a third-party application code created with labwindows CVI (attachment: scissor lift CVI code.rar) which is used for our control of movement of CT scans. I want to serve the Labview 8.6 my main software for data acquisition and software interface for my development. My idea is to create a dll from this CVI code and called the dll with Labview library import function is shared.

  My problem is that I am no expert in CVI programming if anyone can help me how to create a dll from this code? or any other suggestions to implement this conversion?

• How to share an action to several test USE?

  Hello

  In fact, I don't know how to define the topic exactly.

  My request is as follows:

  For example, I have a signal generator and four DUT.

  Signal diagram 1 WE-> batch (4 USE test...) -> model OFF Signal 1, Signal model 2 WE-> batch (4 USE test...)... then on...

  I am stuck how to set the action in the teststand and make once instead of 4 times.

  Something similar for the recall of ProcessSetup, pre-batch and PreUUTLoop,

  but I wonder if there is a way to call an action once in the multiple UUT in the MainSequence.

  Could someone give me any suggestions? Thank you very much!

  Hey William,.

  You will probably want to use the option "only a thread" of a synchronization of the batch section to do this. Looks like you already use the Batch process template, so it should be relatively easy to implement. If it's one step, you can go to the sync step settings tab and change the setting from batch synchronization . If several consecutive steps, you can use the modes enter the sections synchronised and synchronized output of the step batch synchronization type.

  In addition, we have an example that demonstrates this feature. You can find it at \Examples\MultiUUT\BatchUUT.seq. If you look at the stage set room temperature , you will see that it is configured in this way.

• passing a reference structure in a dll (cvi) of EEG, a mistake-17502; System-level exception.

  Creates a container that matches parameter in cvi dll.  I have the container facility by checking the death of struct C using packaging of 8 bytes.  With the help of the adapter of the CVI has created an action.  When the step is executed, I get this error (17502; Except for system-level).

  Have you created a type of data customized to represent the struct (you say that you have created a container)? You specify the field for each variable type structure in the custom data type? You must configure each field to say TestStand what data type to use, for example, a number can be a double, int, short, or char, and TestStand needs to know that in order to create a corresponding structure correctly. Did you create an instance of this type to pass into the dll function? Thanks for posting the definition of structure, you use c if possible, also, please describe exactly how you configured each variable in the definition of type (custom data type), that you have created. If you are able to provide more information, we can try to see if there is a problem with the custom data type configuration.

  You can also take a look at what makes your function, the function code could lead to a breach of access or another exception of system level. You can launch the editor of sequence of CVI process debugging to debug your code module, or change the setting of the ICB card adapter configuration run the code a an external instance of the CVI.

  Hope this helps,

• Error-17004 only when you use CVI RTE

  I am not advocating a solution. I plead for measures of additional debugging I can try to determine what is happening.

  I'm trying to call a function in a built CVI DLLS (INSTR.dll) my TestStand sequence. My DLL linked statically to a second DLL (SYSTEM.dll) including the SYSTEM.lib library in the project of the INSTR. SYSTEM.dll is linked statically to a library of utilities. DLL SYSTEM and INSTR residence in the same folder, and the utility library is located in a folder in the environment variable %PATH%.

  When I put the CVI adapter to run in an external instance, my function work correctly. But when I put the not to run with the CVI RTE (whether through the adapter or the option "Always run In Process", I get an error saying that the DLL cannot be loaded:)

  "Error loading step 'Action' sequence"MainSequence"in the folder"Test.seq". Cannot load DLL or external library 'C:\Temp\test.dll '.

  Code error-17004, could not load DLL or library.

  Source: "THOMAS".

  I tried to use fast (from Windows Sysinternals) and it shows that all my DLLs are found in the course of her probe and are loaded correctly.

  Even if I run the sequence of CVI as "The executable to debug" Editor, I get the same problem. When I do this, I put a breakpoint in my DllMain function and this function is never called.

  If I use a test client executable located in the same folder as the SYSTEM and INSTR, it loads the dll correctly. (But I just realized that the test client is statically linked to the dll INSTR, while TestStand dynamically load the DLL; I'll have to try to change the test client to do this)

  My problem is that I can not reproduce this with a simple set of DLLs, so I can't give an example. I tried to use fast and dependency walker (even if it's expired) and they did not help.

  Someone at - it other ideas or tools that I could try?

  Well, I feel stupid. My project of junior dll and therefore my dll, was named "SYSTEM" (the name was given to us by the customer). And of course, this causes collisions of naming when you try to load this dependency by using the CVIRTE (the development environment must use a different dll loading order).

  I added a prefix file name and everything works now.

  Sometimes, it is more clear what lack us.

• How can I convert a LabWindows/CVI 2010 project to a Visual Studio 2011 project?

  I have a good size project, 12 source files, headers 14, 1 uir, I want to be able to edit and compile in MS Visual Studio 2011, MSVC ++.

  I remember that we tell him that LabWindows dropped support for C++ in 2008 and is more had a wizard to convert projects. I know that I can follow the path of the DLL, but I have never created a DLL before and don't know where to start with it. What would be the best way to go about this conversion?

  CVI 2010 always supports the Assistant Conversion of Visual Studio to Visual Studio 2005/2008. We are not planning to add support for VS 2010 in a later version.

  If you need a project to VS 2010 now, you can use the Visual Studio 2008 conversion wizard, and then upgrade the project VS 2008 for VS 2010.

• Share permissions Windows Server R2 2012 - Folder Redirection-

  Hi all

  I have a simple question:

  I'm following the instructions below to create shares folder redirected to a Windows 2012 R2 file server.

  https://TechNet.Microsoft.com/en-GB/library/jj649078.aspx?f=255&MSPPError=-2147217396

  Orientation specifies the minimum NTFS permissions for users to create their own records in respect of each redirect root action - that I followed.

  However, management does not have the minimum share permissions required for each action.

  I found some old directions below that specify minimum share permissions required for each action - this guide is connected to Server 2003 however:

  https://TechNet.Microsoft.com/en-us/library/cc775853 (v = ws.10) .aspx

  This policy specifies the minimum share for each share of redirection root permissions.  He says that the Everyone group requires no authorization. When I create each action, the default permissions correspond to the "Everyone" group full control.

  So my question is:

  It's recommended to let everything everyone default permissions under total control, or should I uncheck the boxes allow for reading, editing and full adjustment - actually no permissions for the Group everyone on each action of the root.

  Thank you

• How to play all the actions with a single click

  Help, please

  The first action that a defined action play than the rest of the actions in this action the value he plays all actions. This would require a Photoshop script to retrieve all loaded action games and do the action of each. Why would you perform actions at random.

  As the first action in the game was the last action recorded in the whole of the action. Started with a snapshot of brand named normal and then select which snapshot then play the next action in the game, select the snapshot normal and play the next action is repeated until the rest of the action in the game have been played. Then a stop message appears.  The other actions in the game to make a group add their effects and make a snapshot.  If you uncheck the stop step you could same batch of this action, the judgment would stop the batch.

  Just expand the actions and measures and read the steps. Actions are easy to record and edit. The range of action is an action editor full function. You can simple step and change at the same time.  Action of reading is a good way to learn how to use Photoshop and you'll know that if an action will destroy the work that you have gifts on a document like flatten you work.

• debugging error in CVI to within TestStand, whole plant TestStand app

  good, maybe it's not technically a 'crash', but the end result is the same.   Here's the scenario:

  I'm debugging a DLL created by CVI in TestStand.

  the DLL has a runtime error that needs to be debugged, so I BREAK and launch debugger CVI.

  Finally the CVI debugger must be dismissed (say for a fatal error), and a popup says "this will end the process being debugged.  You want to put an end to this process? »

  Can we assume that the CVI is the process ending, right?  Well, apparently not, because if I say 'Yes' it requires an immediate stop of TestStand and let the DLL terminated in CVI.   which is not very useful, so I quit that too and reopen TestStand.   that gets pretty boring.

  any suggestions or advice on how to stop this behavior occurs?

  Hi rjohnson,.

  You follow the recommended procedure for your debugging DLLs?  Details of the exact steps taken to reproduce the behavior can be useful, but I would like to first of all make sure that you follow the steps in knowledge base.

  One thing to note is that TestStand itself uses the CVI runtime engine, so if we are closing the debugger CVI I understood why he could stop TestStand (although it is understandable that it could be quite annoying).  Any subject, if you let me know more details about what you are doing, I can look at the issue a little more away.

  Best regards

  John
