I get "dynamic memory is corrupt" when I call HarmonicAnalyzer function

Hello,
I am using a PCI-6025E to acquire analog signals. I want to measure the THD of some of them, so I have copied the function "Total_Harmonic_Distortion" from the THD_Analyzer.prj example of NI.
Sometimes, my program crash when it tries to execute the HarmonicAnalyzer function.
My program is multi-threading, the acquisition and the THD measurement is made in the same thread.
Someone can help me to fix this problem?
Thanks

Dear SebastianN,
thanks for your suggestion. I have tried to call the "CVIDynamicMemoryInfo" before the HarmonicAnalyzer function, but it has no effect on the program itself (I get always the memory corrupt message).
Yesterday I tried to call the Total_Harmonic_Distortion only if the RMS value of my buffer is greater than 1.0, and I replaced all my malloc functions by calloc functions. Till now it seems to work, but I cannot understand why, and I'm not sure that really I fixed the problem...

Dynamic memory is corrupt (Labwindows/cvi 2010)

I have a multi threaded application....where I have a buffers allocated ineternally in the threads,,...A user interface is present to abort the therad execution.
Here is the code in one of the threads (NOTE: status is set by a user button to EXIT the program):
int EthernetDataStructureThread (void *functionData)
    CmtSetCurrentThreadPriority (2);
    EthernetData GetData={0}, *data=NULL;
    data = &GetData;
    /* Use a buffer to read the data from the queue which is coming from TCP read with fresh data */
    const void *BufferEth;
    int BytesRead=0;
    int BytesWritten=0;
    char ReadErrorMessage[256];
    BOOL bitset = FALSE;
    if ( (BufferEth = (EthernetData*)malloc(EthernetDataSize)) != NULL)
        while ( !status )
            BytesRead = CmtReadTSQData (Queue_TCPRead_EthernetData, BufferEth, EthernetDataSize, TSQ_INFINITE_TIMEOUT, 0);
            memcpy (data, BufferEth, EthernetDataSize);
            /* Empty the queue so that we don't have data in next time. */
            CmtFlushTSQ (Queue_TCPRead_EthernetData, TSQ_FLUSH_ALL, NULL);
            //Pass on the data to the Main thread
            BytesWritten = CmtWriteTSQData (Queue_EthernetData_Main, BufferEth , EthernetDataSize, 1, NULL);
            if ( BytesWritten != EthernetDataSize)
                 free(BufferEth);
                BufferEth = NULL;
                exit(0);
            Delay(0.02);
        if (status && !bitset)
            free(BufferEth);
            BufferEth = NULL;
            bitset = TRUE;
    return 0;
My problem is: free(BuffEth) always says Dynamic Memory is corrupt......When I put a breakpoint and keep seeing the resource tracking window, I can see it getting executed fine as the resource tracking window greys out the memory block....but then suddenly free wants to exceute again...and causes the "dynamic memory is corrupt" error.
I am using LABWINDOWS /CVI 2010 SP1 in WinXP.
Please help me ASAP....very much appreciated.
Regards
NITIN

Thank you for your reply Jackie.
I am calling Free only once...there is an If condition there.
See the attched video for my problem...Free frees the memory block (see the greyed out portion in resource tracking window but still the statement controls remains there and free executes again, throwing error).
Do you think it is some sort of bug in LABWINDOWS.
See the attached video.

LabVIEW PDA reports COREDLL.DLL error when using Call Library Function Node

I'm trying to build a LV PDA app that calls an external DLL file built using embedded visual C. When configuring the Call Library Function node I select the stub DLL, configure the I/O parameters and select OK. When the configuration dialog closes I get the following error:
LabVIEW: LabVIEW.exe - Unable to Locate Component
This application has failed to start because COREDLL.DLL was not found. Re-installing the application may fix this problem.
I do not get this error when using the configuration dialog in the example VIs.
Any suggestions as to the cause and/or the solution?
Thanks,
Ryan

Hello -
When you create a PDA VI that calls a DLL, you must include the .c or .lib file that corresponds to the DLL. Take a look at these documents:

What is an element,when we call a function write_from?

what is an element,when we cal a function write_from what to assign for ELEMENT and WINDOW...?
Edited by: Alvaro Tejada Galindo on Feb 20, 2008 4:37 PM

Hi shekar,
The main reason of specifying the Function module Write_Form is to make the values visible in the particular window of the form.
For Ref, see the Below Function Module:
CALL FUNCTION 'WRITE_FORM'
EXPORTING
    ELEMENT = 'HEADER'
    WINDOW = 'MAIN'
EXCEPTIONS
    ELEMENT = 1.
In the above example, I need to declare a element in the Main window. So I have passed 'MAIN' in window and 'HEADER' in element.
REASON OF SPECIFYING:
Suppose you want to display the values the internal table say suppose it_itab. If you specify this in the sap script like &it_itab-f1& or &wa_itab-f1& without using write_form wont work.
So this will be specified as,
SE38:
Loop at it_itab into wa_itab.
CALL FUNCTION 'WRITE_FORM'
EXPORTING
    ELEMENT = 'HEADER'
    WINDOW = 'MAIN'
EXCEPTIONS
    ELEMENT = 1.
endloop.
Inside Script:
Inside the Main window:
/E     HEADER
      &wa_itab-f1&
what happens is after the loop statement as soon as it encounters the write_form, it searches for the element 'HEADER' in the Main window and values become visible in the form.
If u need any more details, please tell.

Layout - not recognize the element when i call the function write_form

Hi experts,
I got a layout(se71) that not recognize the element that i add in the MAIN window when i call the layout from a program.
what could it be?
i add the element in se71.
any help will be appreciated.
Michal.

Hi!
the write form that u are calling should be as below....
CALL FUNCTION 'WRITE_FORM'
   EXPORTING
      element                  = 'ELEMENT'
      window                   = 'MAIN'
    EXCEPTIONS
      element                  = 1
      function                 = 2
      type                     = 3
      unopened                 = 4
      unstarted                = 5
      window                   = 6
      bad_pageformat_for_print = 7
     spool_error              = 8
      codepage                 = 9
      OTHERS                   = 10.
IF sy-subrc <> 0.
    MESSAGE 'MAIN window not called properly'(006) TYPE 'E'.
ENDIF.                               " IF SY-SUBRC NE 0
in the layout see if the code there with data element is proper as...
/E ELEMENT
   &var&
Also this write_form FUNCTION MODULE should be called b/w OPEN_FORM and CLOSE_FORM Function Modules.

Failed to run parallel path when using call library function node in LV2009

I have a problem with two parallel paths not being run in parallel on LabView 2009.
See the image below.
This code initializes an external device, the upper part contains a call library function node to download my code into the device. When done, the function returns and the "Done" flag is set to True.
The lower part contains a call library function node to check the download status, reporting the percentage of downloaded code.
This updates a progress bar that is referenced by the calling VI module and this works fine in LV 7, 8 and 2011. The lower path of the VI updates the progress bar while the CLFN in the upper part is still downloading code to my device.
Somehow, in LV2009 this does not work when running this inside my application. When running just the calling VI (the window showing the progress bar) it works but not when that VI is called by my application.
Is there some limit on parallel threads that is different in 2009 than in other versions ?
Or is there some other problem in 2009 that might cause this problem ?
My labview version is 9.0f3 (32-bit).
Regards,
Rob

I've just installed the DETT tool and checked what the different versions of LabView do.
In LV2009 the application instance runs in a thread (5) but the modal dialog (the VI above) then drops to thread 0 and stays in thread 0.
In LV2011, stays in the same thread as the application instance and only a trigger event (this could be the progress bar reference?) is executed in thread 0.
So it seems there is a 'feature' in LV2009 where modal dialogs are by default not following the preferred execution system set in the VI properties ...
When I change this from "same as caller" into another thread (I used "other 1") then my progress bar works as expected.
I'm not a LabView thread expert (not even a novice ) so I'm just guessing that "other 1" as a thread is OK. This VI only runs during startup of the application to download the code to my device.
To answer Ben's question: "What thread does a modal VI run in?":
In LV2009, the modal VI runs in thread 0 (UI thread ?). When the preferred execution system is set to another thread, the modal dialog still starts in thread 0 but then switches over to the other thread.
In LV2011, the model VI runs in the caller's thread (preferred execution system set to "follow caller") from start.
Thanks,
Rob

System.AccessViolationException Attempted to read or write protected memory. This is often an indication that other memory is corrupt. when executing compiled query

Hi,
In our company we have a very large application that has thousands of compiled queries, and we've been getting randomly AccessViolation exceptions randomly that crashes our process.
This error happens randomly in several locations, always with the same top stack trace (data and queries are always different). do you know what could be causing this issue? or what we can do to trace the problem?,
I have collected memory dumps of the error to get the stack trace and next are the stack lines that always show at the top of it:
