CVI execution Profiler - overhead DLL

Hello

I use the CVI execution Profiler toolkit to analyze system performance when one implicitly that linked DLL is called from an exe application.

It appears that many statistics that the component time % for the exported DLL function is roughly half of the total time for the component.

For example (with "dll_function" selected in profile):

+ exe_function

-50% dll_function

DebugPrintf 48%

OtherFunction 2%

Would this coorelate time with an overload of the call of the DLL?

Thanks for any help regarding this.

jharris66,

I think that might be a safe assumption, but given that I don't see the same behavior on my system, I can't confirm if it's because your DLL is more complex than mine or because something else contributes to the synchronization. Would it not possible to see a screenshot of the Profiler and code in your DLL function?

  • CVI execution Profiler appears (necessary registry cleaning method)

    I installed 2010SP1 CVI / CVI 2012SP1 and execution Profiler Toolkit and even if I call the function CVIProfSetCurrentThreadProfiling 1/set of profiling in the compilation options, at the end of the programme, the Profiler does not appear.

  • Execution Profiler causes error after that it is disabled.

    Hi all

    I have a set of software that we use the CVI execution Profiler with.  I built the version with profiling enabled in the build options which also added the merge module in the build (see CVIProfilerMergeModule.jpg).  I got what I needed the profile tool, but now I can't seem to turn it off.

    I disabled in the code and the build for the project options and I deleted all of the software OR of the target machine (including the manual removal of the dll cviauto.dll and duration of the windows/system32 folder).  And yet whenever I have installed my new, disabled Profiler, construction, I get the error seen in ProfileError.jpg on start up.  How can I get rid of this?

    Thank you

    Judy

    The error indicates that the Profiler calls code in your program, but the Profiler is not installed. Make sure that you rebuild your CVI program and all CVI DLLs you call with disabled profiling. To make sure you really all rebuild, mark all the source files for recompilation and then build. If not, remove the cvibuild directory and then build. If you have any instrument (.fp) files or files .obj or .lib in your project, make sure that they are also recompiled - remove the .obj and .lib files and make sure that ICB RECOMPILE their source. If you relink only the project without recompile all the source files, you have to the object code who is callling the Profiler.

  • Two parallel executions, calling a DLL function

    Hello

    Since this test takes about 6 hours to test my USE, I plan to use the parallel model to test 2 UUT at the same time in parallel.

    I implement the test code as a DLL of CVI.

    However, to my surprise, it seems that the steps that call a DLL function actually traveled in one series, not in parallel:

    Test 2 power outlets if one enters and executes a DLL works, the other waits for the first to complete its operation and return. While the other runs on the same copy of the DLL, so that the DLL global variables are actually shared between executions.

    So if a DLL will take 5 minutes to complete, two executions in the running at the same time take 10 minutes. This isn't a running in parallel in every way.

    What I want and expect also TestStand, was to completely isolate the copies of these two executions DLL such as test two casings could run at the same time the same DLL function by arbitrary executiong their copy of the function, completely isolated from one another.

    So they separated globals, discussions, etc., and two parallel jacks take 5 minutes to run a step, instead of 10.

    Such a scenario is possible?

    If not, how can I use my test in parallel (in truly parallel) when the use of 2-socket test?

    (1) Yes, he'll call the multiple executions in TestStand calling into the same dll in memory the same copy of this DLL. Thus dll called in this way must be thread-safe (that is written in a way that is safe for multiple threads running the code at the same time). This means usually avoiding the use of global variables among other things. Instead, you can store the thread shows in local variables within your sequence and pass it in the dll as a parameter as needed. Keep in mind all the DLLs your dll calls must also be thread-safe or you need to synchronize calls in other DLLs with locks or other synchronization primitives.

    1 (b) even if your dll are not thread-safe, you might still be able to get some benefits from parallel execution using the type of automatic planning step and split your sequence in independent sections, which can be performed in an order any. What it will do is allow you to run Test a socket A and B Test to another socket in parallel, and then once they are then perhaps test B will take place on one and test one run on the other. In this way, as long as each test is independent of the other you can safely run them in parallel at the same time even if it is not possible to run the same test in parallel at the same time (that is, if you can not run test on two Sockets at the same time, you might still be able to get an advantage of parallelism by running the Test B in one take during the tests in the other. See the online help for the type of step in autoscheduling for more details).

    (2) taken executions (and all executions of TestStand really) are threads separated within the same process. Since they are in the same process, the global variables in the dll are essentially shared between them. TestStand Station globals are also shared between them. TestStand Globals file, however, are not shared between runs (each run gets its own copy) unless you enable the setting in the movie file properties dialog box.

    (3) course, using index as a way to distinguish data access are perfectly valid. Just be careful that what each thread does not affect data that other threads have access. For example, if you have a global network with 2 elements, one for each grip test, you can use safely the decision-making of index in the table and in this way are not sharing data between threads even if you use a global variable, but the table should be made from the outset before start running threads , or it must be synchronized in some way, otherwise it is possible to have a thread tries to access the data, while the other thread is created. Basically, you need to make sure that if you use global data which the creation/deletion, modification and access in a thread does not affect the global data that the other thread use anyway in or we must protect these creation/deletion, modification and access to global data with locks, mutex or critical sections.

  • Conversion of shares CVI to C + c++ / action dll in TestStand 4.2.1

  • CVI DLL using the reminders of Message Windows

    Background:

    I had a CVI wound around a third-party DLL executable application.  Recently, I've built a few LabView modules and wanted to use the features in the code of the CVI.  I deleted as much as I can from the code of the CVI and built a DLL out of it, so now that it's a call to a third party DLL DLL of CVI.  The third-party DLL uses windows messaging to communicate with the CVI DLL.  I wanted not to re - write the functions already developed in CVI in LabView (much too much effort).

    Problem:

    The problem is windows messaging in CVI uses the InstallWinMsgCallback and binds it to a group of experts.  The events are not processed until you call RunUserInterface(). RunUserInterface does not return. Therefore, any LabView module that loads this DLL crashes, waiting for the DLL back.

    Does anyone develop a CVI DLL, which uses internal reminders, which can be called from an external process?   Anyone have any ideas on how to get around?

    Daniel,

    In fact, I came across the solution even before that you posted.  One thing I noticed however was that it was a little unpredictable when the message would be received.  It turns out that defining the InstallWinMsgCallback to intercept that in_queue worked without needing a processsystem looping events.

  • Why should I copy of a CVI DLL compiled in the System32 folder?

    Hello

    I've been letting the compiler CVI copy of a DLL (project) in the windows\System32 folder.

    It was mainly to leave more than 1 other executables CVI, installed in different folders under \Program Files\

    Discover and share this code of the DLL.

    In addition, when you build the kit distribution for the DLL, I directed the DLL must be installed in the System32 folder.

    When you introduce this concept in a review to an other software engineers, a mechanic found that the System32 folder should be reserved for windows, hardware drivers, etc.. My CVI DLL needs to reside in the working folder of the executable main partner, or any other location. His concerns were uninstalling and updating process, and if the DLL were at a location specified by the installer, it would be easier to follow, etc..

    I'm assuming that NEITHER recommended CVI to "COPY IN the \Windows\System32 folder. Why?

    Should my fellow engineer some friendly advice?

    [BTW, he used NEITHER CVI occasionally, especially with other languages]

    Thank you ALL

    Scott Youngren with CVI 8.1.x

    Hi Scott,.

    Even if we are aware of them or not, most programs use System32 as their destination of DLL.

    I myself wouldn't mind too much about.

    Have you seen this document?

    You can install to a different location and use the PATH environment variable where you can not convince that system32 is ok.

  • spend a CVI to TestStand function reference tables

    I need to switch tables (double, for example) a CVI function (usually a dll), return to TestStand.  and vice versa.

    I followed a method that uses features of TestStand CVI such as 'TS_PropertyGetValNumber' and 'TS_PropertySetValString' and I understand how simple values, but the tables are killing me.   I do not see why it would be so difficult, so I must be missing something fundamental

    Here is a simple example of what I'm doing.   I need to add a way to pass an allocated array of doubles (as declared and held in TestStand) in the CVI function where it is called 'values', have my CVI function fill this table of the 'values' and then pass the array back.

    void TestStand_DUT_Transfer (CAObjHandle seqContextCVI, char reportText [1024],)
    short * errorOccurred, long * errorCode, char errorMsg [1024])
    {
    error int = 0;
    char response [DUT_TS_MAX_BUF_SIZE] = {'\0'};
    Double delayResponse = 0.0;
    ErrMsg errMsg = {'\0'};
    ERRORINFO errorInfo.

    get the double value of TS
    tsErrChk (TS_PropertyGetValNumber (seqContextCVI, & errorInfo, 'Properties.Delay',
    TS_PropOption_NoOptions, & delay));

    /* */
    / * How DO I GET AN ALLOCATED TEST DOUBLES TABLE? */
    /* */

    Send command to the device, return a response string and double values table

    DUT_TS_ErrChk (DUT_Transfer (delay, response, values)); //<=== here="" is="" "values"="">


    /* */
    / * I PASS SUSTAIN HOW THE VALUES BACK to THE TEST BENCH? */
    /* */

    Send the char string to TS
    tsErrChk (TS_PropertySetValString (seqContextCVI, & errorInfo, 'Properties.DUTResponse',
    TS_PropOption_NoOptions, response);

    Error:
    If (error! = NO_ERROR)
    {
    DUT_Error_Handler (error, error);
    * errorOccurred = TRUE;
    * error code = error;
    strcpy (errorMsg, errMsg);
    }
    }

    Thank you for the review.

    well, I received a response OR support.  I guess that's a common question since they have an example written, but for later use (since I couldn't find an answer by searching on forums), I will post it here:

  • Run the CVI in Visual Studio code

    Hello world

    I tried to get a CVI code to run in Visual Studio using this guide (http://zone.ni.com/reference/en-XX/help/370051V-01/cvi/usermanual/prjbldmenuextcomplrspt/). So far I've managed. However, I was faced with a non-fatal errors. Apparently, Visual Studio is not following them. Also, fatal errors do not produce a meaningful error message. Is there a way to get these error messages from inside Visual Studio? Maybe there is that an event reminder/whichI can use.

    Thanks in advance.

    The feature you describe is called "user protection". In addition to reporting the pop-up windows error codes, it also warns you if you access an invalid memory, data types to pass to functions that expect different data types, detects local variables uninitialized, etc...

    Unfortunately, the protection of users only works for programs built in debug mode using the CVI compiler. If you generate your source code in Visual Studio, the compiler VC injects not the information necessary to protect the user from working.

    The only way you could get this works in Visual Studio would be if you could somehow isolate all your CVI code in some DLL that build you with CVI, then call this DLL from the rest of your program, what you have created with Visual Studio.

  • Merge the output dll dll dependencies

    Hello

    I created a project CVI which generate output dll: main_driver.dll

    This dll uses the low level dll: driver1.dll, driver2.dll...

    When I create my output dll: main_driver.dll, I still need to copy the dll of low level in my output folder (low level dll appear as to be among the project DLL dependencies).

    It's not really practical.

    Is there a way to merge the low level dll in my main dll (not to be visible, not to copy multiple files when I export my dll of a program)?

    Thank you

    Gregory

    It seems to me that you are hard to understand what is being said here. If all you have is a DLL file and a .lib file, you will need to distribute the DLL file, there is no way around that. The .lib file indicates that the compiler and linker how to resolve function calls, it does not include the code. To actually embed code in your DLL, you must have the source code files or object as well as the files .lib that you add to your project and then the linker can include the necessary code in your DLL.

    If you don't have source code or object, you must distribute the dll. To do this, you must change the configuration of your distribution kit to include these DLLs in the kit.

  • Third party compiled .dll throws COFF header link error bad member library

    Hello

    Has anyone worked successfully through the binding process and building third-party library files into an executable LabWindows?

    Specifically, I am trying to build an executable in CVI which depends on .dll and .lib files generated using the minGW compiler. (CCG)  This always results in a failed attempt to link with:

    «Aborted load library ' library path/name'.»»»
    And:
    "Header Member bad COFF library."

    I read the docs of minGW, to check, it produces complaint COFF files, by default, but obviously there is something that I missed.

    The dll is simple (two exported functions) and programme aid is even simpler, a main() with a single call to one of the dll_exports.  The following files are included in the attached zip file:

    files for building executable in LabWindows/CVI:
    LWCVI_use_test_dll.c
    LWCVI_use_test_dll.CWS
    LWCVI_use_test_dll.prj
    test_dll.h
    test_dll.lib
    test_dll.dll

    files for the creation of DLL using minGW

    test_dll.h

    test_dll.c

    The following #define is also used to export the minGW project function

    #define DLL_EXPORT __declspec (dllexport)

    Any help will be greatly appreciated
    Thank you
    RYK

    There is something wrong with test_dll.lib, but I don't know what it is.

    You can, however, generate an alternative import within the ICB library comes from the test_dll.h file. Open this file in CVI, remove the #include line, then use the Options | Generate the DLL import library... menu item to generate a new library.

    The import library that I generated using this method is attached.

  • imaqReadAVIFrame retrieves the empty image under certain conditions?

    Hello

    I'm having a problem where imaqReadAVIFrame (.) is the white recovery (all black images) under certain conditions.  The conditions seem to be when the height of the AVI file is equal to or greater than the width and the height is an odd number.  AVI files created by using the various AVI NI Vision (IMAQ 4.6.1, IMAQdx 4.6.1) functions in an application created in CVI 2012 on a computer running Windows 7 64 bit.  AVI files use MJPEG compressor, and they play back fine in an external program like VLC or Windows Media Player.  Any ideas on what this could be?  My solution for now is to not to allow the creation of AVI files where the height is odd and equal to or greater than the width that is not a boring restriction, but it seems like there's something weird happens with imaqReadAVIFrame().  I can provide some AVI files if necessary, but they are 16 + MB each.

    TStanley,

    I managed to reproduce what you see with your .avi files in a program I wrote.  I built a LabVIEW program that creates an AVI file which can be saved to memory and then uses code from the example finder to read who created the file.  I build the file to your specifications at the height is greater than the width, and the height being an odd number of pixels.  Something interesting about this, however, is that it seems to be a point where an odd height is acceptable.  Once you go below the height of 291 pixels, any odd height then works.  The files that I used are written as read in LabVIEW, but that the configuration should be irrelevant because we are seeing the same issue.  In addition, LabVIEW and LabWindows CVI calling the same dll to actually set up the code.

    In this, I think this question arises from the nature of the way you compress the. AVI file.  If you are interested to read a bit more about it, a useful link can be found here:

    http://www.manifest-tech.com/media_pc/avi_formats.htm

    However, what I think is happening, is it that MJPEG file compression format translates into creating files that cannot be read by our software unless the height in pixels is a multiple of 2 or the size of the file is below a certain limit.  To fix that, there is a simple solution. Compress the file with any of the other compression methods available (DV video, Cinepak Codec, codec Intel IYUV, Microsoft RLE, Microsoft Video) and you will be able to open the file without the black screen.  This worked for me and should solve all your problems.  I hope this gives you a bit of insight.

    Kind regards
