leak memory in the dll with a function imaq

• Memory from the Flushing call library function node

  I use the function call library (COLD LAKE) node to load some dll dynamically in a same vi.

  I use a loop for to send the DLL files or a table to COLD LAKE to load the different dll.

  For the first iteration, the COLD LAKE works very well, but for the second iteration and so on can not replace the output variable, and continue to repeat the result of the first iteration.

  Is there anyway to clear the memory of COLD LAKE, so that I will get the correct result for DLL 2nd and so on?

  I understand your message, you have different dll, which returns an array of LabVIEW.

  This table can be of different sizes according to the DLL you are calling.

  I think that you are having a general misunderstand about LV memory management. I think that your comments refer to the data space LV has allocated for the table, this has nothing to do with the DLL itself said!

  LV works memory about conservative. So if you allocated a data space, execution of a new of the same VI will try to reuse this dataspace. So the tables are not released if the VI will slow.

  That being said, the table itself will not reduce its size.

  The only question I have on this: you still have all the available values? If the new call returns the three values (out of 33), is the rest 30 items "the old value"?

  For ANSI C dll - it is common that the DLL also returns a scalar value "arraysize". If you got that, you can use the Array subset function to retrieve valid values.

• Will be the leak memory for the queue when it is used in producer and mode of consumption data acquisition transfer different size table.

  In data acquisition, I use a loop to query the data from the hardware, another loop to receive the data from query sent by queue loop.

  Each time the size of the transferred data matrix is perhaps not the same, so the system can assign different table size and recycle frequently.

  It cost memory leak. Or it will slow down the performance, given that the size of the array is not fixed, so everytime need to create a new array of size.

  Any suggestion or the best method.

  If I understand your description, your DAQ loop acquires data with the parameter of the function of reading-'1 ' for reading at the DAQmx samples. This translates into different picture sizes.

  Passage of these tables directly to a queue is valid and she didn't mind important in performance (at least AFAIK) and it certainly does not leak memory.

  So the question is more or less:

  It is valid that the consumer receives sizes different picture for analysis? How your consumer manages these tables?

  hope this helps,

• Leak memory in the routine of Winhttp 6.1 WinHttpSendRequest() on Windows 7

  I posted the following question in https://groups.google.com/forum/# microsoft.public.winhttp! Forum/Microsoft.public.WinHTTP with the subject 'leak memory in WinHttpSendRequest()'.

  I think that this function of WinHttpSendRequest() still leaks memory in Windows 7 (WinHttp 6.1), here is what I have:

  Platform: Windows 7 Enterprise (version 6.1 SP1) 64-bit platform.
  WinHttp: version 6.1.7601.17514.
  Visual Studio version: Microsoft Visual Studio Ultimate 2013, Version 12.0.31101.00 update 4.
  Memory tool leak detection: performance, using "private bytes".
  Symptom: With WinHttpSendRequest() call memory continue to increase even if it looks like a square, but the trend going upwards. Without calling WinHttpSendRequest, the trend is pretty much flat line, even if it looks like a square.

  Here's the code,

• Leak memory in the rings image under Linux

  Hi all

  I have a very serious problem, that I didn't have in the previous version of my app and one of the only addition I've done is to use the rings of the image. The app uses 6 MB more every minute. If I remove the rings, it stops. It could be a bad lead, so I'm writing a test case, but is there that a list of memory identified leaking somewhere?

  Thank you.

  Hello William,.

  I've studied this and confirmed what you see. There is indeed a very serious leak in the Linux module. I'm really sorry for the inconvenience that was done to you. We have created an internal bug reported for this question (414435) and it will be fixed soon.

  To answer your last question, it is not yet a more recent version of Linux than 2010, but there will be an update to the Linux module later this year, and it will include this fix.

  I have not yet studied the issue with CanvasDrawPoly, but I'll do it soon.

  The error with anti-aliasing is expected since this feature has been added in 2012.

• For the complex data type, how to generate the Dll with compatible interface to C/C++

  Hello

  I used the Labview FPGA module to develop test equipment. Now, I need to write a driver that is to be a Dll with compatible interface to C/C++ for this equipment. So that my client who is familiar with C/C++ can call the driver without any study on labview. But I had a few problem on how to convert labview for C/C++ data complex data type. To clearly explain to my question, I have attached a simple example. (see attachment) I try to generate a Dll for the attached example VI and get the the function prototype at the head of the files as below:

  ' void OpenFpgaReference (LStrHandle * RIODevice, TD1 * errorIn, LVRefNum * FPGAVIReferenceOut, TD1 * errorOut).

  As you have known, the type of data "LStrHandle * RIODevice" and "LVRefNum * FPGAVIReferenceOut" Labview data format are. C/C++ do not have this kind of data type and can not reconige it. As a result, I can't call the Dll of C/C++ programming language. How to convert these two data type of labview for the C/C++ compatible data format, and then build the Dll? Anyone know about this?

  The answer is really apprecaited! Thank you in advanced.

  As I found in the following article:

  http://digital.NI.com/public.nsf/WebSearch/FB001AA027C8998386256AAD006C142D?OpenDocument

  LVRefNum is the name of resource of LabVIEW VISA or refnum, and "it is impossible to convert LabVIEW VISA name of resource or refnum VISession valid ID."
  This means that external code modules can not access & control the session VISA which is open by labview. But for my purposes, I will not attempt to access this VISA extenal code(C/C++) session. I just hope that save this session VISA in the external code once I opened it in Labview dll; and pass it to the labview dll when needed. While I have not need to login again when I need to control the device. Is it possible to do?

  A LVRefNum is really just a single int32 value. Its meaning is useless for other environments than those who created it so that you Michael not any what in C/C++ caller but pass it back to other functions in your DLL, but this often isn't a problem at all.

  You can take the following statement of the LabVIEW extcode.h headers and add them to your delabviewed header files to make it work in such a way.

  #define Private (T) typedef struct T # _t {void * p ;} * T}

  Private (LVRefNum);

  The LStrHandle you must set a standard C string instead in your export DLL and document what is the size of the string buffer should have if it is an output parameter.

  TD1 error clusters should also be divided into their parameters (C compatible) separate for all items or just to the left of suite entirely.

• warnings to leak memory for the elements in a form

  After getting the leak memory, look at DropletEventServlet in the Navigator component of/dyn/admin, and you can see the accumulation of mappings element of the page in question form. DropletEventServlet is a component to extended global (regardless of the scope of managers form she monitors) and does not remove the entries over time (which is why it is important to not use IDS in the form element cards FormHandler, and he issues a warning once you 500 for a form).

  My guess is that the bug you see is a fixed bug CCS been resolved in more recent versions of the ATG (2007.1 and later versions). You can see a newer version of the ATG to see if the form is always encoded in the same way.

• 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.

• Leak memory in the Convolution

  The VI attached shows a memory leak in the Convolution routine in LabVIEW 8.6.1.  There is no leakage of memory in 8.2.1 - I have no other versions to test it on.

  Cheers ~ Greg

  Hi Tim,.

  Given that we develop are more for LabVIEW 8.6, this will be something that you need a solution to workaround or update for 2009.  The leak occurs only when you set the size of "Dimension X".  And he was set for 2009.

  See you soon,.

• Image is not displayed in the shape of the APEX with utility function APEX

  Dear experts, APEX,
  
  As I am new to oracle apex development. I just created the basic employee information form where I download the picture of the employee. Photography is transferred, but it does not display correctly. I already spoke of the sample database application to display the image.

  That is why, in my application code is not perfectly rendered and syntax is not over.

  the following characters are rendered like this. : & lt, & quot, & gt, & amp.

  So, is this the reason for not displaying the image?

  Yes.

  To get a displayed item to render in HTML, in the definition section Security value escape special characters notitem.

  For a column of the report, ensure that the column attribute text to display as report is report Standard column rather than the default display text (escape special characters).

  Use a part of the Image display and declarative BLOB support instead of this manual method clumsy.
