• 'Internal error' when starting a machine virtual

  Hello

  I'm under Fusion 6.0.2 on OS X 10.9.2.  This is a new installation of 6.0.2 on a machine which was new two weeks ago.  My VM is Windows 7 64 bit.  My VM worked before I upgraded to 10.9.2, but I don't know which is linked.  Now, when I start the VM, it quickly fails with a dialog box that indicates "internal error."

  I found this thread where a few users have had the same symptoms:

  Internal error when you start a virtual machine in Fusion 6 - Mavericks host

  I tried a little things listed, with no luck:

  You can also check $HOME/Library/Logs/VMware/and $TMPDIR/vmware-$USER for log files from the model vmware-vmx-* .log?  If there is none, would you mind to do what follows?

  -Add the following line to $HOME/Library/Preferences/VMware Fusion/config (please do not hesitate to change the path to something else)

  vmx.log.temporaryFileName = "/tmp/vmx-temp.log".

  -Start the virtual machine.  When the error is observed, join the file specified above.

  There is no files in a path.  I created the configuration file and added the line, set 777 permissions on the two directories, started the virtual machine (it failed once again) and verified: STILL no files in two places.

  Thank you.  Could you do the following, and then try to switch on/off the virtual machine again?

  • Set your unlimited base file size limit: ulimit unlimited-c
  • In Fusion, go to settings-> advanced and choose ' Hang/Crash' to the way of solving problems.

  Please let me know if the error message changes and if there is no base generated in /cores file.

  The error message has not changed.  I had to force-shutdown my VM to change the ways of solving problems (which was not obvious how to do!).  It has not generated a /cores base file.
  

  It's intriguing.  Let's try the virtual machine running from the command line.

  • Leave the merged UI.
  • From a terminal, run
    • sudo/Applications/VMware Fusion.app/contents/library/services.sh--debut
    • / Applications/VMware Fusion.app/Contents/Library/vmware-vmx-debug - x Users/kamil/Documents/Virtual Machines.localized/CentOS 64 - bit.vmwarevm / CentOS 64 - bit.vmx

  That would be if all fine print some messages in the terminal that helps us diagnose the issue further.

• Error 1097 when calling DLLS in LabView

  I get an error 1097 when calling the LabVIEW provider library. Curiously, the error, the DLL routines still seem to do what is asked of them.  This is the test code.  It opens an Ethernet connection to a controller of axes Galil, he asks (possibly) the value of its internal clock, and then closes the connection.  Each call library function returns error 1097 but "valve function" I32 error number is always zero. Open function causes the connection to be opened, the command function causes the send command and receives a reasonable answer, narrow funtion seems to cause the connection to be closed.

  

  Here is what I see when I run the test:

  

  Also directly configure call-library functions, as I did in this VI, I also tried using the import-shared-library Wizard to create a vilib of functions of the DLL and I get the same behavior and errors when I use these functions.  I tried to tweak some of the data types in my configured manually call library functions to see if I could find a combination that worked better with the library, but had no luck there.

  I use the x 86 version of the DLL with v2014 LabVIEW 32-bit on a 64 bit windows system 7.  I see that the error on the two computer systems of different work configured in this way. I see a similar error on a home computer with just the RTE of 2014 installed. The manufacturer says they can not reproduce the error. I always saw the error over multiple versions of their library DLL.

  In the attachment ZIP it has a link to the DLL library on the manufacturer's website. There is also a copy of the VI, the DLL and a large part of how-to-use documentation that accompanies the DLL.

  I was hoping that someone who was familiar with the use of the call-library function might take a peek at what I do and see if an error could be spotted.

  Unable to find an error, I did, I would be happy to suggestions on how I could solve this. Little seems to me like there may be a problem with the library. The manufacturer, Galil, said that they have opened a log with OR to see if NEITHER could help but since Galil said they can not reproduce the problem and provide an example of the NC, it really went anywhere.

  Given the decoration of symbol names as exported by the DLL I "m convinced that you must change the stdcall calling convention.

• Calling DLLS in LabVIEW

  Hello

  Below is the code written in LabWindows in which dynamically access a Dll using Windows API LoadLibrary(), GetProcAddress(), and FreeLibrary().

  Successfully, I could load the library and get the procedure address using library calls node in LabVIEW. But got stuck after that.

  As I am not good in C/C++ coding, ask someone to really help me to write the same thing in LabVIEW.

  Kindly do the needful.

  #include   // Function prototypes.
  #include     // CVI Active X definitions.
  #include 
  #include    /* Needed if linking in external compiler; harmless otherwise */
  #include 
  #include 
  
  typedef long __stdcall( *OLECREATEOBJECT)(char*);
  static  HINSTANCE  Hinstlib;
  static  long  gvntISystem;
  
  long CviCreateFastObjects (void)
   {
  OLECREATEOBJECT procAdd;
      pStrTempmem      = (char*)CA_AllocMemory(1);
      Hinstlib = LoadLibrary("FastTrio");
      if( Hinstlib != NULL)
  {
          procAdd = (OLECREATEOBJECT) GetProcAddress(Hinstlib, "OLECreateObject");
          if(fRunTimeLinkSucess = (procAdd != NULL))
  {
          gvntISystem = (procAdd)("FAST.IMFASTSystemInterface");
          return 0;
          }
          else
          return 1;
          }
      else
          {
  return 1;
          }
  }
  

  All the information you need are in the C code.

  • OLECREATEOBJECT is typedefed just after all the #includes at the top.  It returns a long integer (typically I32 in LabVIEW, but could be I64 on a 64-bit operating system) and takes a string as input.  It uses the standard windows calling conventions, not the C calling convention.
  • LoadLibrary and GetProcAddress are used to get a pointer to the function (procAdd).  This is handled in LabVIEW, by filling in the location of the library and the function in the call library node.
  • The library of appeal in LabVIEW node must also be set to the standard calling convention and return value (I32) and list of parameters (a string) must be set.
  • the function is used to set gvntISystem with a constant of entry 'FAST. IMFASTSystemInterface ".  In LabVIEW, a constant string of wire at the entrance and read the return value.
  • You can implement the audit, thus using the call library errors node error output.

  Good luck!

• Efficiency call DLLS in Labview

  Hello

  I'm working on a labview program for the treatment of the data in real time.  Thus, code running efficiency will be critical.  I wonder how about the cost of calling DLLs.  Similarly, what the call cost of the subprogrammes.

  To implement the same function, the call of a Subvi will be faster than calling a DLL?

  If I can develop all screws Sub in the main program and delete all the calls, which will be much faster?

  Can someone give me any clue or guideline?

  Thank you.

  CRXX wrote: [...]

  What is the OS you are using?

  Since you ask in general, I answer in general:

  This question cannot be ansered. This is a case-by-case-thing and must be assessed individually.

  Most of the effect will be the memory management: which allocates the amount of memory? When it's done?

  Memory of ESP. allocation mess up determinism, if a DLL can perform worse than pure code LV (given a BONE of RT LV). But it might be preferable for some algorithms encapsulated... no one can say in general.

  Perhaps the most important question is:

  How many times is that the code (DLL vs Sub - VI) called and how short is its runtime? If the load of execution: calling code relationship is very low (-online 1:1), it is best to "solve" the subcode. SubVI Inling is a valid way in pure BT (from 2010).

  If the code is called rarely, this whole discussion is somehow obsolete as the overload of calls will be negligible, even if it would be quite high...

  And no, C is not faster as LV by definition. It also depends on the task and how you implement it...

  hope this helps,

• Internal error when calling "catalog: createKeyword.

  Hi all

  I'm in the decision to make the migration process in Lightroom. An important aspect is that I'm able to import my existing keywords to my photos (currently in ACDSee) somehow. I managed with the easy part already: conversion of categories in a text format based on TABS and import it as keywords in Lightroom.

  Now, I want to associate images with the keywords already imported. The following thread led me to a speed very quickly: http://adobe.hosted.jivesoftware.com/thread/1033982?tstart=0

  But now I am somehow hit. I can get the keyword root directly, and I am also able to get her children. Unfortunately, whenever I call createKeyword with a parent I got the following error message:

  "An internal error has occurred:?: 0: attempt to index a nil value.

  Any ideas what could be the cause?

  Here's the script, by encapsulating the problem, if it helps:

  local LrDialogs = import 'LrDialogs'
  local LrApplication = import 'LrApplication'
  local catalog = LrApplication.activeCatalog()
  
  
  MyMenuItem = {}
    
  function MyMenuItem.runProcess()
      catalog:withWriteAccessDo("setKeywords", MyMenuItem.setKeywords)
  end 
  
  function MyMenuItem.setKeywords()             
            local targetPhotos = catalog:getTargetPhotos() 
            if targetPhotos ~= nil and #targetPhotos > 0 then 
                      -- LrDialogs.message(#targetPhotos)
            else
                      LrDialogs.message( "No target photos." )
                      return
            end 
  
  
            -- ( keywordName, synonyms, includeOnExport, parent, returnExisting )
            local myRootKeyword = catalog:createKeyword( 'People', nil, true, nil, true ) 
            if myRootKeyword ~= nil then
                      LrDialogs.message(myRootKeyword:getName())
            else
                      LrDialogs.message( "Keyword has not been returned." )
                      return
            end
    
            local childs = myRootKeyword:getChildren()
            for i,child in ipairs( childs ) do
                      LrDialogs.message(child:getName())
            end
            -- Shows Friends, Others, ...
    
            LrDialogs.message( "createKeyword is about to be called" ) 
    
            -- Crashes after this line "An internal error has occurred: ?:0: attempt to index a nil value"
            local mySecKeyword = catalog:createKeyword( 'Friends', nil, true, myRootKeyword, true )
            if mySecKeyword ~= nil then
                      LrDialogs.message(mySecKeyword:getName())
            else
                      LrDialogs.message( "Keyword has not been returned." )
                      return
            end
  end
  
  
  import 'LrTasks'.startAsyncTask( MyMenuItem.runProcess )
  
  
  
  
  

  Thanks for the advice in advance.

  Kind regards

  Thorsten

  Ah, the problem is that you try to call myRootKeyword:getName() before leaving the catalog:withWriteAccessDo ().  The doc of catalogue: createKeyword() says:

  Must be called in one of the with__WriteAccessDo doors. The new keyword is not available for access until that function returns.

  If instead, you restructure your code like this:

  local myRootKeyword
  catalog:withWriteAccessDo("setKeywords", function ()
      myRootKeyword = catalog:createKeyword( 'People', {}, true, nil, true )
      end)
  

  It works very well.

  Furthermore, your "Accidents After this line" comment was wrong.  I suggest to you that use debugging tools, which will make it much faster to identify your bugs. It will take time to hang it to the top of the first, but he will pay fairly quickly.

• "27049 internal error" when you use recovery with Equium A60-692 utility

  TOSHIBA SATELLITE A60 - 692

  I'm trying to fix a friends laptop. The laptop computer wouldnâ? t start, would go to the blue screen just before the came WinXP loading screen then will re-start. I used a USB 2.5 HDD enclosure "to copy important files on my laptop and then formatted the drive of my laptop. I put the HARD drive in the Toshiba and have used the CD of restoration via an advanced option. on exactly 9mins 50sec time on the recovery process, an error message appears (27049 internal error). After that, it goes to a screen of style BACK with a little more information. Essentially by specifying that the error is "cannot read FILE_BITMAP MFT entry.

  I cleaned the CD
  I swapped the CD drive with my laptop
  Quick formatting it formatted, it is full
  Used the basic option where it does itself and it ERRORS with - not enough space on the partition - there is no partition! or if there's empty sound

  What can I do?

  Hello

  I think that the HARD drive is broken, because if you receive an error message with words like "MFT" (meaning MasterFileTable) then you can expect that the HDD has serious problems.
  OK, easy to talk to it s fast without knowing the machine and so on, but I know a similar error and I can give you the advice to probe hard disk errors.
  You can do this with the help of the "ultimate boot cd" which is a very interesting tool when you need information about your computer or you want to just check if everything works well.
