• Passing a reference to queue as a sequence with LabVIew API parameter

  Hello

  I'm running a sequence of Labview with the entryPoint.Run method.

  Now, I want to pass a reference to queue to TS for use as the parameter for a stage of the action (the action must information sent through this queue). I tried to move the queue as a parameter for the valVariant parameter of the object of Subproperty seuqence.

  LabVIEW throughs 1 error when I try to setValVariant.

  The reason why I want to do it is because I want to integrate the execution of the sequence in my draft framework for an actor.

  Is it better to move the refs to the queue as a reference to be able to send data to an application running?

  Thanks in advance

  Hi Michael,

  It is not possible to use references of LabVIEW in TestStand queue, since they do not share the same instance of the application. You can pass a reference to queue as an integer (U32 or I32), but you can not use in TestStand.

  I found 2 ways for you to use:

  You can use the Action engines in LabVIEW to encapsulate the queue. There is some information about this option in this thread:

  Solved: queues of LabVIEW and TestStand - Forums of Discussion - National Instruments
  http://forums.NI.com/T5/LabVIEW/LabVIEW-queues-and-TestStand/TD-p/2554231

  However, with this option, you must make sure that the motor Action shift register leaves no memory

  .

  The recommended practice is to create the queue in TestStand using Synchronization Manager and then open this queue in LabVIEW. An example is available for this option:

• Pass a reference to the shared variable

  I use two shared variables in a loop where I write one and read each other.  I need to repeat this loop 5 times, but each loop uses a different pair of shared variables.  These variables are shared between a vi on the computer and a cRio.

  It would be ideal to incorporate this loop into a Subvi where I can pass a reference to the two shared variables in and then read and write in threw these references.  Then I could just call this Subvi 5 times, instead of copying and pasting the loop 5 times.

  Is it possible that I can accomplish this?  I can't find an example that would achieve this.

  Thank you

  If I understand correctly, you can use the mode programmatic access to shared Variables and it would work.

• Resizing a picture of structure within a DLL using the memory manager

  Hi all

  I dug deep inside the rooms, but has failed to find a solution to my problem.

  I am building a dll, which made a few imageprocessing and must return an array of structures to labview, with a struct for each element of the image.

  Because I do not know the number of items in advance and at the limit of the number is a number of magnitude higher than expected, I don't want to allocate such a huge part of memory before the dll call in labview.

  In an older version, I used a table 2d for the elements, where each line contains the values of each element. Here I used the function NumericArrayResize, which worked very well. But I have to add several subprocesses and using structs (or clusters in labview) seems to be more useful and more clean to me, I had also some items back and Foreword climb several times.

  For example, a struct element must take 2 single beds and 1 uint32. My question now is, how can I resize this table of struct with memory manager, functions as the NumericArrayResize functions is not suitable for this purpose?

  (Access to an array of structures inside the DLL and after reading the changed values in Labview is surprisingly easy )

  Thanks in advance

  Well, I was able to solve it myself. I found this thread, where the first rolfk post made me think. It seems to me that the numericarrayresize function behaves very similar to the function realloc of c. so I used the unsigned int type 8 (which is just a byte) and multiplied by the number of bytes used by a struct, in my case 12 bytes (4 + 4 + 4) and multiplied it by the number of structures (elements of the image) I. Fortunately, it worked and the block of memory has been resized, exactly as I wanted it to be. Important note: do not forget to adjust the size of the handle element, otherwise Labview does not know the size has changed.

• Pass by reference

  Hi all

  I'm developing an application for the tests used in automobiles. I just had a tot that is possible to pass the array by reference. I know that the method of passing by reference by getting the reference to the table and pass the reference to the Subvi. To do this I need to create a display board and reference for the same should be passed to the Sub - VI. But this is nothing but pass the data to the Subvi by value. The only difference is that the table indicator will not be created in primary vi rather a control panel will be in Subvi.

  Is it possible to directly wire data without creating a control wire Subvi and Subvi table, use as a ref table and retrieve the data. You mean, son of data must be connect to the Subvi terminal, but terminal in sub - VI should give the Ref for that data.

  All ideas are welcome.

  Thank you

  Yogesh

  Maybe you are looking for a reference value of data? It can be a 2D array, for example.

• Passing a reference to a type definition for a Subvi

  I created a type definition that I would use in my application. This definition of particular type is also the control of front panel to my top level VI. I wanted to pass a reference to this control to my sub - VI so that they could dereference as needed and in very rare cases, update the values on the front panel. However, as I created the application I noticed that I was breaking the control reference that I have updated the type definition. This implies that they type changes the reference that I change the type definition.

  How can I do to build the reference I need or there at - it another way to proceed that works as well. Even if I can't make a reference to the control that is bound to the type definition, I'm ready to move to a Variant that can accommodate the reference until I can build the type of data (reference) inside my SubVis.

  Hello

  You must simply pass a reference of generic control to the Sub.vi and then cast to the specific typedef. You will need to place a control dummy of this typdef on your Sub.vis Frontpanel and hide.

• I can't pass a reference of function to another function?

  Hello
  
  Reminder of basic:
  I am trying to create a custom preloader class that uses a table to store a URLRequest objects queue, to load in the order. I have no problem with the queue or get the loader to load the URLRequests in order.
  
  I can't seem to pass a reference to a function (address think of c) in my preloader class. I want to convey the function reference to serve the event listener for the given URLRequest.
  
  Signature of the function:
  public function addItemToLoad (item: URLRequest, notify: FUNCTION_REFERENCE)
  
  Anyone know what the syntax is to pass the address of a function to be called at a later date?
  
  Think that
  FunctionName
  vs
  Nomfonction()
  
  Thank you
  Nomadic design

  Thank you

  I missed the caps. I tried the function, but the compiler received errors.

  I've actually taken a step further. I'm now pushing the function references in an array and passing the array in the function.

  public function addItemToLoad (item: URLRequest, notify: Array)

  I realized that I might need to notify several objects of full charge.

  Thanks for your help.

• Failed to create system restore point exception exception c:\windows\system32\shell32.dll,control_rundll,"c:\windows\system32\sysbm.cpl",system

  Original title: I can't do a restore point.

  I get exception c:\windows\system32\shell32.dll,control_rundll,"c:\windows\system32\sysbm.cpl",system what can I do?

  This has happened for a very long time.

  Does really say '... sysdm.cpl "?"

  Is that what the text complete and accurate of what the message said exactly?  (there is no sysbm.cpl in XP, but there's a sysdm.cpl).

  What happens if you click on start, run and enter in the box:

  sysdm.cpl

  Click OK - the system properties box opens?

  What happens if you click on start, run and in the type box (exactly):

  %SystemRoot%\System32\restore\rstrui.exe

  Click OK - is the open window of the system restore?

  What is exactly the process (step by step) you are using when you try to create the restore point and when in the process you see this message?

  I think it's a miracle that the Microsoft support engineer can provide a link to an article when the error message report you is a little out of whack and articles doesn't mention your error message at all.  It's real good troubleshooting or clairvoyance!

• Passing a unique structure through the functions of customer/ServerTCPRead/write and making sure that all data is transferred

  I use the CVI TCP media kit at my request and I am curious about the following code:

  ClientTCPRead

  char * buffer;
  int messageSize;
  int bytesToRead;
  int
  bytesRead;

  / * Find messageSize and allocate a buffer properly... * /.

  bytesToRead = messageSize;

  While (bytesToRead > 0)

  {

  bytesRead = ClientTCPRead (connection handle,
  (& buffer [messageSize - bytesToRead], bytesToRead, 0);

  bytesToRead = bytesRead;

  }

  OK, this works if you tank elements of the array, but what happens if you pass a structure of arbitrary size?  If you read/write the bytes read or written and that you get all the data that you have asked, what do you do at this point to get the rest of subsequent data?  For example, replace the "buffer" of type char with a structure of a type defined by the user with a size of 100 bytes or something to that extent.  You make a request for read/write and read/wrote less than 100 bytes.  How do you get the rest of the data?  ICB doing something in the background?  I could use this code with several structures, but then again, a particular Member of a structure is not the size of a byte as a tank.

  Much appreciated,

  Chris

  The solution is to use a pointer to char sunk to allocate the data transmitted.  The only problem is that this buffer must be a pointer to the data type of the structure before a tank troop can be used for a successful program compilation. Thank you for your help.

• Passing arrays in function in a dll

  Hello

  I have a dll below function

  FI_API uint8_t FI_capture_settings_init_wrapper (uint32_t * cap_set, uint32_t sen_set *, uint32_t * rec_set uint32_t * exp_set)
  {

  * cap_set = (uint32_t) 55;

  *(cap_set+1) = (uint32_t) 56;
  cap_set [2] = (uint32_t) 57;
  sen_set [0] = 54;

  Return 1;

  }

  I call the function of library in labview. I initialize a global array of variables and pass it to the FI_capture_settings_init_wrapper(). After, I display the values in the table an indicator table as shown in the picture. The value is supposed to change in Labview. The API returns a value. But the table is not changed in labview. Please see my camerainit.vi

  Your shared variable is an external resource that contains data, so when you read the excerpt from LabVIEW variable, shared data and copies in a local array, which is then passed to the DLL function. Because the table is not used after the call to the DLL, it is simply thrown then. Then you read the shared variable and LabVIEW retrieves its data, which has not been changed since and copy them again in a local array to show on front panel indicator. If you want the shared variable to represent the new data, you must rewrite the right Terminal to the explicitedly compose the node of the library in the shared variable. And the variable shared again just after reading is obviously completely false performance wise since the wire that came out the library node call already contains data and should therefore be wired by later use.

  If your first problem is that you treat a shared variable as something that LabVIEW could be considered as an internal pointer that she cannot, the shared variable is hosted by the shared variable engine, which is a separate process and data access is on a TCP/IP based protocol. Even if it is a control on the front panel the code would that he should do, since LabVIEW as a data flow language will copy the data of the control in a local array and passing to the DLL, and unless you're writing the changed data that comes out of the right side of the rear Terminal in the control the data in the control will NOT change.

  Then learn how data flow programming! LabVIEW is generally not about data as a reference that can be modified by reference to a function. Whenever LabVIEW suspect a function might modify the data passed in, it MUST create a copy of the data so don't up don't not the concept of stream which is the fundamental basis of LabVIEW programming by the window. Forget shared, globals variables and build local even in LabVIEW as a general programming, especially when you come from a traditional programming language such as C (++), VB or c#. A thread of LabVIEW is THE variable, and you should only use global and local variables if it is strictly necessary for something. Especially a shared variable as an external resource connected through TCP/IP is a killer of absolute performance and should only be used if you need to transfer and access the data between different (possibly the network connected) process.

• Passing a reference MovieClip of Parenthood to button event?

  I try to refer to a movieclip which was adopted through the first class (Builder/instance, tried both) but failed to get an instance of key event to recognize. Because the button based around an event, I'm not sure of how to reference. I've stripped a lot of the code, but has left the classiquee function as button events are related to a structure of dynamic loop, the main reasons why I can't move the buttons to a different class.

  The example looks like this:

  package {}
  
  import flash.display. *;
  import flash.text. *;
  import flash.utils. *;
  import flash.events. *;
  import flash.net.URLLoader;
  import flash.net.URLRequest;
  import com.greensock;
  com.greensock.easing import. *;
  com.greensock.plugins import. *;
  
  Thumbnails/public class extends {Gallery
  
  public void Thumbnails()
  {
  trace ("LOCATION: thumbnails");
  }
  
  public void initThumbs (root_mc:MovieClip, site_mc:MovieClip)
  {
  
  trace ("THIS, PARENT:" + this, parent, site_mc);     WORK
  
  }
  
  private function _onDataReady (evt: Event): void
  {
  
  function overThumb(evt:MouseEvent):void {}
  TweenLite.to (site_mc.gallery_mc.title_mc.txtTitle_mc,.5, {alpha: 100});
  TweenLite.to (site_mc.gallery_mc.title_mc.txtRollover_mc,.25, {alpha: 0});
  }
  function outThumb(evt:MouseEvent):void {}
  TweenLite.to (site_mc.gallery_mc.title_mc.txtRollover_mc,.5, {alpha: 100});

  / / Only trace site_mc
  TweenLite.to (site_mc.gallery_mc.title_mc.txtTitle_mc,.25, {alpha: 0});
  }
  function upThumb(evt:MouseEvent):void {}
  
  } / / END OF upThumb()
  
  } / / END of onReadyData
  
  } / / END OF class
  } / / END OF packet

  I'm trying to figure out how to get the reference site_mc to the key event so it can trigger others clips nested inside (gallery_mc, etc.). If it's AS2 it would be a piece of cake, but now I have all these invisible walls for the passage of variable.

  If someone can tell me where my logic is wrong with that, so I can connect the dots, I would love.

  you don't need to redefine something nested clips.  you just need to get a reference to site_mc outside your Builder.  When a parameter (such as site_mc) is passed to a function (constuctor, another method of the class or only a function defined on a movieclip timeline simple vanilla), the parameter is only available in this function for this particular function call.  If you want available elsewhere, you must define a variable that is available elsewhere.

• Reference to Struct to DLL (library function call)

  I have two functions written in C, which takes the reference to a struct.

  Statements:

  IpAddress_Parse (IpAddress, address const kChar * text)

  ConnectIpAddress (connection, const kIpAddress * address)

  typedef struct IpAddress
  {
  int version;
  address to unsigned char [16];
  } IpAddress;

  Extracted from:

  Sub main (int argc, char * argv)

  {

  IpAddress ipAddress;

  IpAddress_Parse (& ipAddress, "12.0.1.10");

  ConnectIpAddress (connection, & ipAddress);

  }

  I'm trying to convert above in LabVIEW, but are struggling to. I tried to create a Cluster in LV and analyze the data of IpAddress_Parse() and pass it to ConnectIpAddress() as "Adapt to the Type" nothing helps. Even though I have artificially build a Cluster to move to ConnectIpAddress(), I mistake 1097 of LabView. My cluster included an int and a byte array that follows typedef struct IpAddress.

  Please provide some indication that what I'm doing wrong. Thanks in advance.

  Please submit your LabVIEW code. The IpAddress cluster must contain a 32-bit integer value and a nested group containing 16 U8 values. You can not replace an array of fixed length C with an array of LabVIEW; You must use a cluster containing the same number of items instead.
