Duration of Linux 8.0 CVI crashing in PlotStripChart

I'm trying a quick port of old code CVI 5.5 the CVI Linux 8.0 Runtime. Windows with CVI8.0.1 code from Windows 2000 in an Oracle Virtualbox 3.2 on Ubuntu 8.04 it works so I know that there is no CVI 5.5-8.0 issues >. But after the construction with cvicc the Linux code breaks down by operating on Ubuntu 8.04. Use the KDbg, gdb interface I've isolated to the PlotStripChart() function call. It is this stripchart.prj that is confusing and left me speechless, if I build the example on Ubuntu 8.04 it traces a stripchart very well. I also used the control stripchart on other projects of CVI Linux Runtime and it has always worked. The only difference I could find was this code is traced VAL_INTEGER where the example and my other code has drawn VAL_DOUBLE, but change my stamp of the plot and the PlotStripChart() to use the doubles still does not work. If I comment the unique line of PlotStripChart() in the code, it works very well and seems to work correctly. Its a fairly complicated application that communicates via TCP/IP to a real-time network controller and provides the user interface and functions for our experience of data backup. On some tests without the PlotStripChart() call the saved data and all the results of the commands appear correct, so this seems to be the only way out. Any suggestions, I'm out of ideas and not more clues KDbg/gdb. I'm trying the Beta of CVI2010 Linux Runtime, but given that CVI2010 can't stand Windows 2000 I'm slowed down by having to implement a VM XP (boy of course there are a large number of fixes since my last drive XP MSDN ) and the fact that alien fails to create the 32-bit file on the 64-bit Ubuntu 10.04 I aim currently. I'll have to convert the executable files of rpm on my system to Ubuntu 8.04 32 bit. Not a showstopper, but a waste of time, so I had to put aside for the moment. I have the Runtime of Linux 8.0 CVI apparently work on 64-bit Ubuntu 10.04 so I expect the same procedure should get me go with the 2010 beta once I get foreigners to do the 32-bit deb files in the RPM files.

I have no explanation, but there be bugs in IUR files when using cvicc.

I took an old project of Windows that the above was derived, make minor changes to compile under Linux and low and behold its worked stripchart control!  Then I cut this file UIR stripchart control, removed the control stripchart of the UIR file above and pasted the copied in control.  Then I dragged to the right size and define the scope and the number of traces of what I needed.  Rebuild the project and presto! No crash the stripchart of drawing.

I always the original file IUR in my archives of Windows files, so I will revisit the issue once I get the CVI 2010 beta installed runtime, which will unfortunately be a while as other projects that push down the battery, but at least this port seems usable now.

  • CVI crashes when compiling with VISA

    LabWindows/CVI does not compile when I try to use VISA:

    For a very simple program (only the user interface, no communication instrument multithreading, either), when I include "visa.h", it does not compile and crashes from time to time:

    -When I hit 'Compile', it says "a custom callback raised an exception.".

    -When I type "Debug Project" (Green Triangle), CVI crashes without explanation.

    VISA itself seems to work fine, because I can do a basic with an oscilloscope connected by USB communication using [tools > create a task of e/s Instrument ""] as well as generic VISA Interactive Control.

    CVI itself seems to work fine, too, since I can compile & run programs that use direct access to the GPIB without VISA for example.

    I am running: Windows 7 (64 bit AMD), LabWindows/CVI 9.1.0. (428), VISA Interactive Control (5.0.3 / 4,0).

  • Utility GUI localization CVI crashes when loading of the uir

    I am trying to add multiple languages to my project, using the location of the CVI GUI utility in LabWindows 2010.

    However when I try to load my file IUR in the utility, it crashes (as killed at Windows). The IUR was initially created using LabWindows 6 or earlier, however, it was brought and working in LabWindows 2010 for more than a year.

    Each time, it crashes and I can't continue my work. Is there anything I can try to make it work?

    Thank you

    Chris

    Hi Chris,

    Take a look at the .uir that has been published, it seems that the error is the result of the check. If you remove the two elements that are in the tree control (so that nothing is in the tree control), save and then try to load the .uir in the UI localizer, it seems that the .uir can be recharged on the Locator of UI without error. Alternatively, if you let the elements but change control of chain type (char *) int, it seems to load without causing an error as well. I'll check to see if there is a known issue, but I hope that one of the two workarounds can be used for your application.

    This was extremely irrititating and does not know what the devil.  I have a computer with CVI 2010 and separated with CVI 2009.

    I have a project and the CWS, which was established in 2009.

  • Accident 6.0 CVI photo button

    I discovered a problem with CVI 6.0 that has been driving me crazy for days

    Now, I'm able to reproduce the issue with the simple attached draft.

    I'll give you a brief description of what is happening:

    -J' created two IUR with some image controls and Photo buttons, where I loaded the images with a 32-bit color depth

    -When you run the example (debug or standalone, whatever) you need to press the Press here grey in the first Panel, then the HOME one in the second Panel.

    -If you repeat this sequence several times (5-6 is usually sufficient, but it is possible that you will need to press more than 10 times) the CVI crashes with a first GPF ' "chance in the LoadPanel() function.

    The CVI sometimes crashes with strange errors even if I just open the files of the *.uir inside the editor.

    How can I fix this annoying problem?

    Note: on my PC I CVI RTE 8.0.1 installed, but I tried the standalone exe on a PC with a new installation of CVI RTE 6.0 and it crashes even when

    Thanks in advance

    Hello Vix,

    There was a bug in 6.0 CVI which caused a memory corruption error when. UIRs containing images with certain characteristics were loaded (in the user interface, or through LoadPanel editor). It is difficult to describe what were these characteristics, given that the problem occurred in the image compression algorithm, and so it depends on the color of the image data.

    In your case, you don't have one of these problem images. It is in the 012_SetupGlobals.uir. It is not the image of 'Home', nor the image of great background. This is another image that is used in the 20 smaller buttons. If you remove or replace the image, the problem won't happen again.

    Unfortunately, if the image has been saved with CVI 6.0, even new versions of RTÉ (for example the 8.0.1 you tried) will also have a problem loading it.

    If you really need to use this image, a possible solution would be to save the. IUR in a later version of the CVI, where the problem no longer existed. But if you do this you will no longer be able to load in CVI 6.0, or with version 6.0 of the RTE. Can back up only recent versions of the CVI. UIR versions compatible with CVI 7.1 or later version. This means that you must distribute the RTE 7.0 or later version with your application.

  • With the help of CVIRTE 9 with CVI 6

    I use CVI 6 on XP and that you have an application that has begun to hurt behave unpredictably recently. I tried a trial version of CVI9 and found that using version 9 of the Runtime Engine resolves the problem, even if the application is compiled using 6 CVI. I downloaded the version 9 of the TEN and tried to install on the destination machine (which also has CVI 6 IDE installed legally), but the installer RTE, has refused to install the NTE in Windows\system32. However, if I manually copy the RTE files in my application directory, then everything works fine.

    My question is, RTÉ instalation fails it because it detects that I don't have 6 CVI is installed on the machine, and only through 9 TEN violates so the copyright? If yes then this seems to be a problem as the current RTE (6.0.4.105) seems to be the source of the problems.

    Thank you

    Hey Awd,

    Good afternoon and I hope that your well today.

    I suggest you repair your installation of the CVI run time engine.

    I you also suggest to uninstall the runtime, install the CVI 9 and then try to install 6 CVI - do you need the older runtime for other applications? * Otherwise just uninstall.

    I just installed CVI DURATION 6 then 9 RunTime CVI (excerpt from ni.com site) without problem. But it was a clean machine.

    Please let me know your thoughts,

    Duration of the title - can anyone HELP

    In the middle of my film, I want to insert a title, the default value is time 03:50 seconds, I can't right click to get the red mark and drag it for longer. I even tried to insert a longer video and hoping the title will appear longer than 03:50 second - it just doesn't work. I want to extend it to 20 seconds.

    Can anyone HELP

    THANKS - THANKS

    THANK YOU for trying to HELP MS MVP, but your method works only with the beginning title (which I did), what I'm doing now is in the middle of the movie, when I want to overlay aTitle, this is where I got into trouble, and when I tried to save the movie, even accepting the short duration of the title, the system crash me does not save.  This means thatWindows Movie Maker does not make a title in the middle of a movie, they don't allow that in the beginning and the end?

    THANKS - thanks

    ==================================
    The method that I gave you should work anywhere on the
    timeline... maybe your title is in the track title Overlay?
    And... you can place a title where you want... you
    can even drag one to another position.

    Hello CVI - User!

    I managed to reproduce the bug, and identify the cause of this deadlock. It seems that the ADE 2015 LabWindows/CVI crashes trying to generate the call to GetProcAddress navigation information. The main problem is the building containing the function pointer cast.

    Fortunately, there's a simple solution to this problem: use typedef wrappers during the conversion of the results of the function call for function pointers. In your case:

    typedef BOOL (__stdcall * FunctionType)(BOOL on);

    public static FunctionType F_Ptr;

    public static int LoadDLLIfNeeded (void)

    {

    F_Ptr = (FunctionType) GetProcAddress (DLLHandle, 'F');

    ...

    This work around not only prevents hanging CVI, but also guarantees a good practice for writing cleaner and easier to maintain code.

    Meanwhile, CAR #543277 has been filed, to ensure that this bug will be considered for fixing in a next version of LabWindows/CVI.

    I hope this helps!

    Best regards!

    I tried to follow this tutorial with the USRP 2932, coming soon, but I found out later that I have seem to have none of the LabVIEW Communications. No not those who prevent me from using the USRP radio? If not, then is there any restrictions on what I can do with the radio without communication?

    Hi BreadLB,

    The link to the tutorial you posted is based on LabVIEW Communications System Design Suite, a new software environment designed to accelerate the prototyping of the algorithm and stable air.  It is a completely separate and independent of LabVIEW environment.  See my post here for more details.  You can also download a free 30 day trial copy here.  Your hardware is supported with LabVIEW and LabVIEW Communications.

    The 2932 NOR is a network based USRP, and there a small on-board FPGA.  For this reason, the FPGA on that specific product is not a target of LabVIEW FPGA.  The NI 294 x / 5 x family has a large Kintex 7 FPGA and can be programmed using LabVIEW FPGA and LabVIEW Communications, as in the tutorial you posted.  The 2932 OR can be used with your host PC and LabVIEW for a variety of applications.  Unfortunately the tutorial that you have linked to your post requires the NI 294 x / 5 x hardware and Communications of LabVIEW.  If you have questions about a specific application for your 2932, please post more details and we would be happy to help you.

  • yet another serious UI editor bug

    Hello NO,.

    I just ruined my last book when CVI crashed. I have reproduced this behaviour twice.

    Here's how:

    (1) in the user interface editor, create a new ring of built-in menu (I'm not investigating other ring controls)

    (2) open it to change the attributes of the ring

    (3) open the Edit value/label pairs

    (4) do not enter anything, simply press OK

    (5) press OK to leave the Panel change Ring

    (6) throw control

    You will find that the CVI disappears (not save unsaved files).

    I have not studied whether changes in this procedure would also result in a crash.

    So much for today,

    Wolfgang

    Hello Wolfgang.

    I was able to reproduce the issue and filed a bug with ID 285633 report.  As a solution, you should be able to programmatically set the name of long Panel instead of setting, it is so long in the user interface editor.

    I'm sorry for the inconvenience,
