DLL Keyence LJ - V problem

Hello, I am new in the world of Labview, since I discovered it three weeks ago. I am currently an intern and I have to develop a Labview application using a profilometer Keyence. I need to extract the profilometer of datas and processing them at the same time using Labview. I have a laser head THAT LJ-V080 connected to a LJ-V7001Pcontroller, which communicates with the computer via a USB cable.

Keyence condition a DLL library (LJV7_IF.dll), which is supposed to work with Labview, however I use the tool 'Import shared library' and Labview is unable to recognize the functions contained in the library. It seems that the LONG type is not recognized, which is supposed to be defined in windows.h, right? So I tried including windows.h in the header, but nothing has changed. And I did not understand how to use the preprocessor definitions to solve the problem.

I attached the zip file containing the DLL Keyence and a picture of the error I get. I use Labview 2016 with Windows 7 Professional 64 bit. I'm sorry for the bad English, it is not my first language.

Thank you in advance,

Theo

Hello

Keyence formerly driver LabVIEW for LJ-V7000 series, but I can't find anywhere on the Internet (there is evidence here: https://www.dmcinfo.com/latest-thinking/blog/id/8658/using-lj-v-keyence-lasers-in-labview , but the download link is dead). I remember that he wrapped DLLS that you are using.

Try to contact your representative of Keyence, maybe they'll locate it for you.

  • Cannot get rid of the 'dll' during computer startup problem

    Whenever the computer is started, I get the following error message:

    There is a problem starting TaskSchedulerHelper.dll the specific module could not be found.

    I searched on the window support pages, articles and a few corrections.  I run disk cleaner, I run performance and maintenance patches and still nothing to get rid of this problem.

    Any suggestions? If I'm in the wrong group, please send my request to the appropriate group.

    Thank you

    1. you have a lot of odd entries, some of which may disappear after a reboot.

    2. If you want someone to take another look at the output from Autoruns, next time, save it as "Autoruns Data (* .arn)" and it will be easier to read (it can be downloaded and opened in Autoruns).

    3. with regard to your question with TaskSchedulerHelper.dll.

    • Run Autoruns
    • Select the scheduled tasks
    • Scroll down on the 5th line, which will be probably yellow highlighted and should have the following in the left column
    • \Auslogics\BoostSpeed\Scan and repair
      and what follows in the column 'Image path '.
      File not found: TaskSchedulerHelper.dll
    • Clear the check box in the box at the left end of the line
    • Close the Autoruns and restart; You should see is no longer the message on TaskSchedulerHelper.dll

    If you have already uninstalled BoostSpeed, wait a week or so and if everything seems OK, run Autoruns, look for the same entry and delete it.

    http://get.Adobe.com/flashplayer/

    9 download drivers and full software features

    DAS besagte Projekt ist auf einem server sales und wird über eine operation auf dem Office of the "Mess-Rechners" aufgerufen und kommt yesterday zum Einsatz.

    Before kein problem.

    Wird besagtes Projekt der von einem Rechner aus gestartet, so wird eine Fehlermeldung displaying other.

    Die Fehlermeldung year, dass die before erwahnte .dll found wird nicht gibt.

    ES liegt die nahe, dass die .dll lokal sales ist assumption. ICH habe already eine Suche nach der auf dem Server .dll, sowie lokal auf dem "Mess-Rechner" specification, however ohne Erfolg. .Dll scheint die garnicht zu existieren... verwendet wird die .dll is.

    Die .dll war lokal sales und die Suche-Windows hat einfach nur sehr lange gebraucht, um eine Suchergebnis zu ermitteln.

  • Missing when importing DLL functions

    Hi all

    I created a DLL using Matlab.  When I try to import in LabVIEW (version 8.6 or 2009), most of the functions don't appear.  Any ideas?  This has been done with Matlab R2010a.  I looked through other messages on the subject of Matlab DLL but they were all parties concerned to do anything to work at all.  In my case, certain functions through but not all of them.  I tried to attach files, but it wouldn't let me...

    Thank you and I hope that it is something really simple that I'm dominant.

    -Matt

    OK, I thought about it... This is an annoying problem of a Matlab (I think).

    The problem is that once you import the DLL (and I don't know exactly when) - you can not add more functions of the DLL.  So the first time I tried to do this, I had only one function.  Later, I added more - but they were simply ignored.  I have rebuilt (in Matlab) as a new project, imported from the DLL again, and the problem disappeared.

    It is also possible that it could be a problem of LabVIEW with the file lvlib (?) is not updated correctly, but I do not really - I know how to run now.

  • DLL, error when quiting LabVIEW 2009 on WIN7

    Hello

    I reduced the problem in my EXE application code following joint (see attachment). Somehow the DLL (in User32.dll) calls create a problem when quiting Labview 2009. The Application remains resident in the bar of Windows taskbar and after a while an error pops up about that there was a problem to close the app and it may be reported to Microsoft if you wish. Then a second error message appears before the application disappears from the taskbar. If I remove the DLL:calls in the code then the problems disappear.

    Here I unloaded DLL calls on a special way before quiting LabVIEW?

    Another potential problem not mentioned in this article, it's that you have included your explicitedly user32.dll in your built application. This creates a 200% for sentencing as the kernel32.dll file user32.dll and others are always residently loaded into memory anyway and mapped in the system section of memory of a process. If you apply again to load this DLL by its explicit name, you end up having two copies of it mapped in your memory space of the process and which will cause really weird problems.

    To avoid this problem, make sure that the name of the library within the library node call indicates only the name of the DLL without any path information. Close the dialog box, and then save it. If you reopen the dialog box display the full path but it still save the name only until you make a change in the control of path, date at which you can eventually have a full path again.
