• How does the library function call Labview? Can I emulate using C++?

  Hi all. I recently finished writing a dll CUDA for LabView, and now I'm in the steps of optimization of code, memory management, etc. BUT since my code depends on the entries of Labview (lots of data under types of specific data as table manages and Clusters labview) I can't use the CUDA Profiler or the Profiler VC ++ on the DLL. What I intend to do runs labview and then out of all data entry for the DLL in a binary file and then add an additional function in my code that will read in the binary file, allocate and assign variables to their respective positions, and then call the specific DLL function in Labview. In the end, this miniature function will act as the library function call to my specific group of data entries.

  In any case, I started to make this purchase all my data entry of cluster and it comes out in a binary file. And then I started the initialization of the handles of labview, allocating memory and begins to write the binary data in the memory and it works for integers (ints), floats, etc., but I'm confused on how it works with table handles!

  Some examples of code:

  Sets the Handle for table 1 d for INT
  
  typedef struct {}
  
  	int length;
  
  	int val [1];
  
  		to access the value in a row-online val [Online]
  
  } Array1dInt, * Array1dIntHandle;
  
  int main()
  
  {
  
  	Array1dIntHandle x = new Array1dInt *;
  
  	(* x) = new Array1dInt;
  ifstream file ('TESTDATAIN.dat', ios: in | ios::binary);
  If (file.is_open ())
  
  	{
  
  		file ((char *) &(*x)-> length, sizeof;)
  
  		file ((char *) &(*x)-> val [0], sizeof (int) *(*x)-> length);
  LabviewSpecificFunction (x);
  
  		leader. Close();
  
  	} else
  
  	{
  
  		< "file="" did="" not="" open!"=""><>
  
  	}
  
  	return 0;
  
  }
  __declspec(dllexport) LabviewSpecificFunction (Array1dIntHandle x)
  
  {
  
  ...
  
  }

  However, my program crashes when the table is nominally big, and it is expected, because if we look at the Array1dHandle, it has allocated only enough memory to 1 item of value! YET, somehow, in its magical and mysterious labview is capable of making val [1] be val [HOWEVERMANYYOUWANT], even if C++ 101 says that val [1] is a constant pointer, and even if I dynamically allocated memory another somwhere, I would never be able to put these data in this round!

  Can you explain, or maybe even write example on how I can fool my program into thinking that the binary code comes from labview, so I can then run my program independent of allowing me to profile the functions inside labview?

  I hope that this question is clear and my sample code is also clear, but I'm happy to answer any questions that relate to this.

  Thank you all!

  I think that I thought about it.

  Array1dIntHandle x = new Array1dInt *;
  int tempsize;
  
  file ((char *) & tempsize, sizeof;)
  
  (* x) = (Array1dInt *) malloc (sizeof (int) + sizeof (int) * tempsize);
  
  (* x)-> length = tempsize;
  
  file ((char *) &(*x)-> val [0], sizeof (int) *(*x)-> length);

  Well enough, you will need to make the handle, and then make a new Array1dInt * for him, then read in the length of the array in a temporary variable. Then use this information to then malloc memoery quantity you need for the table and pass this place on the handle. Now the handle will point to the size of the memory and you will be able to access the memory in the format, you've done the handle. Badabing badaboom

• Solution for the mutation of table of error when using triggers

  Hello

  Could you please give the solution for the error table mutation during the use of triggers. I'll give you the simple scenario here,

  I created a trigger on the employees table, whenever all DML operations takes place in the employees table, it must run the trigger body. I intentionally used also of the employees in the body of the trigger table. Please give me the solution.

  Triggering factor:

  create or replace trigger test_trigger

  before you insert or update or delete employees

  for each line

  declare

  an employees.first_name%type;

  Start

  Select first_name from people where job_id = "AD_PRES";

  end;

  DML statement:

  Update employees set salary = 20000 where job_id = "AD_PRES" (I run this query)

  Error message:

  ORA-04091: table HR. Is the transfer of EMPLOYEES, the function of triggering/can not see

  ORA-06512: at "HR. TEST_TRIGGER', line 4

  ORA-04088: error during execution of trigger ' HR. TEST_TRIGGER'

  Can anyone tell, in what other scenarios, we get this error or recursive table mutation?

  Thanks in advance

  Hello

  When you create a trigger on a table, you cannot edit/query this table the trigger is not completed.

  You can use

  (1) transaction of Pragma autonomous

  (2) instead of row-level trigger, you have statement-level trigger

  (3) to 11 g, try with COMPOSITE trigger

  Try below to avoid it (a solution):

  create or replace trigger test_trigger

  before you insert or update or delete employees

  for each line

  declare

  PRAGMA AUTONOMOUS_TRANSACTION;

  an employees.first_name%type;

  Start

  Select first_name from people where job_id = "AD_PRES";

  COMMIT;

  end;

• Create parameters for the WriteData function

  Hello

  How would create parameters for the writedata function to populate the html code?

  Add-Content, $fileName $tableEntry
  Write-Host $tableEntry}

  Thank you

  You specify when you call the writedata function, so I guess it's in the function Get-Cluster.

  You can pass the object you create in the GetCluster function as a parameter.

  Try something like this

  Function GetCluster {
      & { foreach ($Datacenter in (Get-Datacenter)) {
              foreach ($Cluster in (Get-Cluster -Location $Datacenter)) {
                  $clusObj = New-Object -TypeName PSObject -Property @{
                      vCenter = $Datacenter.Uid.Split("@")[1].Split(":")[0]
                      Datacenter = $Datacenter.Name                    Cluster = $Cluster.Name                    HAEnabled = $Cluster.HAEnabled                    DrsEnabled = $Cluster.DrsEnabled                    DrsMode = $Cluster.DrsMode
                  }
                  writedata $clusObj            }
          }
      }
  }
  
  # Function will compile the data passed from the GetCluster Function into HTML table format
  Function writedata {
      param ($object)
  
      $tableEntry = "$($object.vCenter)" +
          "$($object.Datacenter)" +        "$($object.Cluster)" +        "$($object.HAEnabled)" +

• How to change the switch case sub - VI for the Subvi all calls

  Hello

  to make the code more elegant and more reasonable, I source code, often called a Subvi. The Subvi is a box structure. If I add new cases of this Subvi thereafter, I must renew all selectors of Enum for the Subvi handmade calls. It's really annoying.

  Is it possible to pair the picker to the slot - VI for a change in the number of cases will affect all selectors automatically?

  Best regards

  Carsten

  Thank you very much. It works just perfect.

• Does anyone have a solution for the use of Bible Illustrator 3.0 MS8 and MS7

  Original title: program programs Application Applications compatibility.

  Does anyone have a solution for the use of Bible Illustrator 3.0 MS8 and MS7

  What are the requirements of system for this program?

  What version of Windows it says on the package, it was designed for?

  If its designed for an earlier version of Windows such as Windows 95 or Windows 98 or XP, then it is probably incompatible with Windows 8.

  If the product packaging indicates anything in the 1990s OR early 2000s, I am afraid that this is not something that is guaranteed to work with Windows 8.

  You can try the following average time.

  Point to the installation files where they are.

  Right-click on the configuration file, and then click "troubleshoot compatibility".

  Wait, it detects the problem.

  Click on the option "worked in an earlier version of Windows.

  Select Windows 7 RTM or better Windows Vista SP2

  Click next

  Click Start the program, wait, it installs

  When the installation is complete, click Finish and save the settings.

• How to use the node function call library for a function in the dll with the data SUB type

  Hi all

  I would ask for your kind help

  I am facing a problem with the call library node.

  I have a C++ (stdcall) function, which has Sub as data type

  XXXX error code (hwnd, lid, getValue, * Sub data1, * Sub data2)

  data1 and data2 types are constantly changing based on the value of 'getValue '.

  Mainly I can use the call library node several times and adapt each node according to the types of data data1, data2 and extract the values and use in the code. Here is no question. Real question is:

  My question:

  How can I use a node of library time call and make a case according to the 'getvalue', who will control the data1, data2 data type. Here I really seeking solutions.

  My tests:

  I used varaints as entry to the libray call node of the data1, data2 and selected parameters in the call libraby node as "Adapt to type. Here labview just crashed.

  I appreciate your suggestions to feedbackand.

  Thank you

  Karine

  You must allocate enough space for data1 and data2, and then pass a pointer to this space. An easy way to do this is the function to initialize table. Set the U8 type and size for the number of bytes required. Pass this array to the function as a pointer of table data.

  After the function call returns, you need to extract the data in the table. You can do it manually, but a simple approach is to use the array of bytes to a string. Then, in a housing structure, use Unflatten chain to convert the string to the correct data type. This method also converts the "endianness" which will be probably necessary; Be sure to only set all entries for unflatten correctly.

• How to implement a callback to the help function call library function node in LabView?

  I try to call a fuction from a SDK.dll library by using the node call library feature. The SDK has been provided to

  me and I don't have the source code, just the .dll and .h files.

  The SdkSetPropertyEventHandler function has a function of recall as one of its parameters. How to apply the

  callback using the NSI node? I'm a good programmer LabView but this is my first time using the library to call

  Function node. I read all the info I can find on the web site of NOR and the discussion Forum, but can not understand

  This one out. I'm using LabView 8.6.

  The deacribes SDK.h function as:

  Function: SdkSetPropertyEventHandler

  (SdkSetPropertyEventHandler) SdkError SDKAPI
  SdkCameraRef inCameraRef,
  SdkPropertyEvent inEvnet,
  SdkPropertyEventHandler inPropertyEventHandler,
  SdkVoid * context);

  //
  Description:
  Registers a callback function to receive the status
  change the notification events for the States of property on a camera.
  //
  Parameters:
  In: inCameraRef - designate the object camera.
  inEvent - designated one or all the events will be completed.
  inPropertyEventHandler - designate the pointer to the callback
  function to receive the camera property-related events.
  inContext - designated application information must be passed
  way to the callback function. All the data necessary to
  your application can be passed.
  Output: no
  //
  Returns: A sdk errors.
  -----------------------------------------------------------------------------*/

  A separate header called SDKTypes.h file contains the following data:

  typedef SdkUInt32 SdkPropertyEvent;

  typedef void SdkVoid;

  typedef struct __SdkObject * SdkBaseRef;
  typedef SdkBaseRef SdkCameraRef;

  typedef SdkError (SDKCALLBACK * SdkPropertyEventHandler))
  SdkPropertyEvent inEvent,
  SdkPropertyID inPropertyID,
  SdkUInt32 inParam,
  SdkVoid * context);

  Hi Rolfk,

  You are absolutely right. This article describes what you were talking about? I'm just trying to get as much information as possible on this thread if the solution is easier to find for the future. Thank you.

  Yes, but I find the idea of using .net to call a LabVIEW VI as callback function C a bit as using a roll of Steam ironing your pants. Why do it? Well the steamroller has extra security guards that make it less likely that you'll break your pants in the process, but it's not elegant IMHO.

  Write a C DLL that translates between a C callback and a user event LabVIEW using the PostLVUserEvent() of the interface of the kernel to run LabVIEW function seems so eleganter for me. Yes, it's a bit of programming in C, but good!

• E3000 with the same problems on &amp; more here, but no expert solution for the 2 main problems

  

  1 - with regard to support USB connected hard drives that will not transfer data & like to come & go quite often of the view.

  Everything seems like a joke to me, when I read that a lot of people have hard drives USB who worked for a year, & when it stops working or acts upward, we all have a test to see if it connects & works very well on our other connections PC/Laptop & the only advice given, this firmware is upgraded or a list of hard drives that have been tested and work on the E3000.

  2nd - my other problem is that my E3000 now decides of its own to disconnect wireless & cable Communication and then reconnect alone, whenever you feel.

  What makes angry of this problem is that it is abundant in the Forums & I tried all the fixes, but I still have the same problem & sound as good as this device of 2 year, Max is grilled.  As is the case when there is a loose connection that overheated, in what thread or welded metal move when heat is added & move at the time where the heat is removed.

  PROBLEM:

  My touch 1 Maxtor (from the approved list) is connected and playing now you see me & now you don't game.  If I ever try to import or to export any image file or music, the Communication goes & then sometimes will return its own. Working with Game Consoles, when something begins to work intermittently, then it is a hardware problem or software with the device.  It is not a user error, when it worked fine before.

  SOLUTION?:  This is why we are all here. Thanks to a landmark of expert for the same problem that many of us have?

  How about this solution. Why not let all E3000 owners send there wireless routers is not working towards a credit for a new operating model nice. I think that we would all save a lot of headaches & get rid of 25% of all calls for help on this forum.

  Thank you for your attention,

  BigdogTim7

  PS. Please give us/me expert advice on how to solve the problem.  If nobody knows the answer, then Cisco/Linksys looks really bad for selling a router high of $$$, being touted for the games and files sharing multimedia home & it only at this stage.  If it should be recalled, will bring up by all means, or come up with a fully functional firmware.

  Thanks again & hope to hear news good & productive, cause I am so tired of playing with this E3000 & will more than likely stay away from your product for any & all future purchases, no matter where you are ranked (E3000 was 3rd & best prices of the top 3 when I bought it).

  Well, I'm here, not having heard an assumption about my problem, but to get an opinion of experts & solution to my problem, but also all other users of the same or very similar problems.

  I am now a HAPPY 'Belkin N600 DB' owner for only $79.99 @ Wal-Mart/Radio Shack. This new does much more than the Cisco E3000 wireless router & even changed my Modem 100 MB (green) flow out of 1000 GB (Amber Light).

  So, so HAPPY now!
