• Call dll error 1097

  Hello

  I'm reading the data from a capture card in my slot PCIe card. When I call the "Initialize" function from the .dll file that I got with the card, I always get error 1097. 1097 means that the called function threw an error. When I run the program supplied with the acquisition card, the acquisition card still works.

  If I have everything just omit the "initialize" function call and continue with the function that will be called after the "Initialize" function, LabVIEW block (program stops without any warning).

  I also had a LabVIEW program that uses the dll that was supposed to work. But here I get the same error.

  Do you have any idea what normally causes this behavior and how can I solve this problem?

  I have the second post of nathans. 1097 error is almost always an error in the configuration of the right to call library node. And in some cases, there is no right to set up and you need a wrapper DLL to convert between what the library node call allows and what needs your DLL. The reason why it works sometimes and other times not, actually is that it never really works, but sometimes the error that gets caused cannot be detected by the operating system and LabVIEW does not get an exception according to. This can change according to LAbVIEW version, runtime system or development and even recompilation of the code after the small seemingly unrelated changes in demand.

• The DLL call fails when DLL uses a wide range

  I call a C++ dll in LabVIEW 32-bit on Windows 7. I kept getting error 1097 and finally understood it is because the dll uses two large paintings of 5 MB each. The tables are initialized in the constructor of an object, malloc is not used, or whatever it is. If I do the smaller berries, then everything works fine.

  The problem is not difficult to work around, now that I know what is the cause, but can someone tell me why a dll using a lot of memory would be a problem? I feel that 10 MB is really a lot of memory to use on modern computers.

  OK, you can test the appeal of the DLL in a Visual Studio test harness?

  In addition, in case you haven't seen another 'DLL error 1097' son type, here are a few. The cause of 1097 in your case can be illuminated by a multitude of courses of troubleshooting:

• Get the 1097 error when trying to call a Labview DLL

  I had to write a wrapper DLL to use some functions in the DLL to a third party, and I'm having a few problems. I created an executable to test my code and it works fine, but when I try to execute the same function in the DLL that I created in Labview, I get error 1097. I read through most of the posts on this forum about this issue, but none of the proposed solutions are working for me. I'm sure this isn't a question of transfer settings to COLD LAKE because I changed the function so it only accepts a single entry (a number he obtains from a Subvi, which came from the third-party DLL, this entry is working with a bunch of other functions, so I don't think that is the question).

  I have attached the C code that creates the wrapper, but I don't know how it is useful without familiarity with the functions of the original DLL. I hope that someone can spot something basic I am out of my code, but please let me know if I need to call something else.

  I use a Labview 32 bit version 2012 on a 64-bit Windows 7 computer.

  Thanks in advance for any help!

  You should read the documentation on LoadLibrary() and understand. Essentially if you provide a full path to LoadLibrary() the DLL MUST be present at this place so that LoadLibrary() will succeed. If you pass only the name Windows DLL will ONLY search in these places:

  (1) if the module (the DLL) is already loaded it will return a handle to the loaded module and increment its reference count

  (2) if the referencing module contains a manifest (either incorporated into the image module or in a separate manifest file in the same directory as the executablemodule) specyfying a version number for this DLL will load this DLL with this version of the SxS (side by side) location and failure if it is not present

  (3) if the executable load contains a manifest (either incorporated in the executable file or in a separate manifest file in the same directory as the executable file) number specyfying a version for this DLL, it will load this DLL with this version of the location of SxS (side by side) and fail if it is not present

  (4) it will search for the DLL in the same directory as the directory where the current image of the process is loaded. It is NOT the directory of the DLL loading the DLL, BUT the directory where the EXE file from which the process was created.

  (5) in the system directory

  (6) in the Windows directory

  (7) any directory in the PATH environment variable

  (8) the path of current directory which is a location managed by windows by process and changed the two explicitedly when the application calls the API SetCurrentDirectory() but also implicitedly by things like the file selection dialog whenever it is rejected by other means than the undo operation.

  Essentially putting your dependend DLL in the same directory as the wrapper DLL does NOT work when you use the name of the DLL only UNLESS you place the two DLLs in the same directory as your executable file. If you don't want this restriction and want to be able to move these modules together in different directories, you don't have to create the correct path in your wrapper to LoadLibrary(). Basically, you must have the code to determine the location of your DLL wrapper path and then strip her own name and add the DLL name wrapped in it and then move to the LoadLibrary().

  There are several ways to determine the path of the current module. The simplest if you don't mind having the name hard-coded in your code DLL would be to ask GetModuleFileName (GetModuleHandle ("yourDLLname"), buffer, size).

• Error code coming 1097 in DLL call

  Hello

  I get the error code 1097 in the DLL function call. Please find the DLL by calling the function for more information.

  Function: GetControllerListTest (Controller * ptrControllertest, char * max_controller);

   

  Parameter Controllertest details:

  set NO_OF_CONTROLLER 100
  #ifndef CONTROLLER_STRUCT
  typedef struct
  {
  CString name;
  status of tank;
  CString blocked_by;
  Char group;
  } controller;

   

  Data type for the parameter Controllertest is structure. In LabVIEW, I configured the parameter as a cluster.

  name: line control

  status: complete control U8

  blocked_by: control string

  Group: entire control U8

  Could you please confirm it, did I set up the type of data in a correct way?

  I'm getting output empty table and the error Code of the DLL 1097. Can you please tell me where I am missing?

  Thank you

  What type "CString" defined?

  If it's a C++ type, as defined here, then you can not call this function directly from LabVIEW because LabVIEW can not pass of C++ types.  In this case, you will need to write a wrapper (in Visual Studio or another C++ programming environment) which takes a string (character array) standard C as an input, creates a CString from her and calls GetControllerListTest.

  If CString is defined as a fixed-length character array, then you need to replace the strings of LabVIEW with clusters of U8 containing a number of elements equal to the string length (LabVIEW does not support arrays of fixed length).

  If CString is defined as a pointer to a character array, you can pass the data to LabVIEW, but you must call the memory manager of LabVIEW functions to allocate memory for the string data and copy it.

• error 1097 after the call dll function that allocates memory inside

  Hello!

  When a one call my duties in my dll of LabView, I get an error 1097. My function takes a few arguments, and then allocates memory for the measure.

  He doesn't have pointers to this memory area, it's just allocates this memory for himself. I don't know what could be the problem, no doubt, I'm missing something.

  Could you please help?

• 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.

• error when calling NtSetTimerResolution in NTDLL 1097. DLL

  I get 1097 error when calling NtSetTimerResolution in NTDLL. DLL. why?   I scoured most of the posts on this forum describing the 1097 error and tried the solutions without success.

  This is a link to the function prototype (copied below) that I adapted in the node call the attached vi library (you will be asked to locate NTDLL. DLL on your system when opening it)

  NtSetTimerResolution and NtQueryTimerResolution are defined as follows. All hours are stated in hundreds of nanoseconds.

  NTSTATUS NtSetTimerResolution (
  IN ULONG RequestedResolution,
  IN BOOLEAN defined.
  ON PULONG ActualResolution
  );

  Parameters

  RequestedResolution

  The desired timer resolution. Must be the legal scope of the system timer values supported by NT. The standard x 86 systems it's 1 to 10 milliseconds. The values that are within the acceptable limits are rounded to the next higher standard x 86 HAL millisecond limit. This parameter is ignored if the Set parameter is set to FALSE.

  Set

  This is TRUE if we ask a new resolution of the clock, and FALSE if the application is indicating that he hasn't needed a resolution already implemented.

  ActualResolution

  The resolution of timer in effect once the call is returned in this parameter.

  Woohoo! I solved the problem.

  I was using a copy of NTDLL. DLL C:\Drivers\I386\SYSTEM32\NTDLL here. DLL (version 5.1.2600.1106)

  instead of C:\WINDOWS\system32\ntdll.dll here (version 5.1.2600.5755).

  An observation aside Interestingly enough, I did, when I tried to put the old version in C:\WINDOWS\system32 to see if it was just a problem of dependence, rather than a version number, I couldn't do it!  I tried renaming C:\WINDOWS\system32\ntdll.dll C:\WINDOWS\system32\ntdll.dll.old and immediately a replacement c:\windows\system32\ntdll.dll pop up would be in his place! I even tried to drag / drop of C:\Drivers\I386\SYSTEM32\NTDLL. DLL C:\WINDOWS\system32\ntdll.dll, it seemed to replace, but a system of security immediately replaced it with the latest version.   WinXP is smarter than I thought, or maybe something like Microsoft Windows Defender Antispyware installed by our company does this.

  In any case, I've confirmed lateer version is necessary because when I copied C:\WINDOWS\system32\ntdll.dll to C:\Drivers\I386\SYSTEM32\NTDLL. DLL, it also solves the problem.

  You might well ask why I did not use the correct version in the first place - well not knowing where he was, I only noticed the old version when I searched for it with my Google Desktop.

• During the selction DLL I always get error 1097

  Hello!

  I would like to include a DLL in my labview program. I fear, I still get the error 1097.

  -------------------------------

  Possible reasons:

  LabVIEW: An exception occurred in the external code that is called by a node call library feature. The exception may have corrupted the memory of LabVIEW. Save all work to a new location and restart LabVIEW.

  How I hired a labview to dll 2D table?

  The size of the arrays are 246 * 310. See c ++ code below!

  ------------------------------------------------

  #include "stdafx.h".
  #include
  const int DIM1 = 246;
  const int DIM2 = 310;

  BOOL APIENTRY DllMain (HANDLE hModule,
  DWORD ul_reason_for_call,
  LPVOID lpReserved
  )
  {
  Return TRUE;
  }

  __declspec(dllexport) double correlation WINAPI (double temp [DIM1] [DIM2], double [DIM1] [DIM2] candidate, long rows, long column) / / both 2D is 246 * 310 is this correct?
  {
  Double sum_quad_temp = 0.0;
  Double sum_quad_candidate = 0.0;
  Double sum_numerator = 0.0;

  Double denominator = 0.0;
  double result = 0.0;

  Double numerator [DIM1] [DIM2];
  Double quad_temp [DIM1] [DIM2];
  Double quad_candidate [DIM1] [DIM2];
   
  for (int a = 0;<=rows;>
  {
  for (int b = 0; b)<=column;>
  {
  to do

  }
  }
   
  for (int i = 0; i)<=rows;>
  {
  for (int j = 0; j)<=column;>
  {
  to do

  }
  }
   
  to do

  return (result); the return type is numeric (double 8 bytes)
  }

  No, no! Simply use the return name double [] [] . C

  double name [dim1] [dim2] is equivalent to double name [dim1 * dim2] and for a function parameter that is also the same as double * name (obviously the last does not apply for variable declarations itself as the first two will allocate a buffer in memory when the last allocates only a pointer, but the extent of passing parameters all three are simply a pointer to a memory area and I think the first two are only valid for the parameters in C++ or maybe C99) so, as you can see it's all simply a one-dimensional array of items. In LabVIEW, you work with your two-dimensional array and configure the library node call accordingly and pass the array as a table of C. LabVIEW pointer then will take care to pass the pointer to the data in the actual table service DLL.

• mcscm.dll + Lib

  Use mcscm.dll. It has 22 functions. The functions are defined in a library file named mcscm.lib. I just called mcscm.dll using node library call to call a particular function. But what the thing is since all this dll functions are defined in the mcscm.lib file, I can't able to get the exact result.

  My question is how to access the .lib functions in LabVIEW. I searched the forum, but all the way, it was the conclusion that we must use LabWindows. Alternatives to use LabVIEW?

  Thank you

  Hi all

  Its mainly because of the bad memory referencing, this 1097 error appears in CLN. I watched a lot of discussions in this forum, and many are answered by smercurio on how to eliminate this error by properly initializing the settings and correct handling of memory.

  Thank you

• Error 1097 - only on executable appeal

  Hello

  I have a vi that uses dll calls to interact with our instrument that works perfectly until I have build it as an application, where it give error 1097.

  I went through the debugging and it fails on the first call to the dll, so I'm sure it's a problem with the way that I call the dll. But I tried including the dll required in every single place I can imagine the search, which includes; Article project dependencies, high level vi, path of Subvi exe path, file data, SysWOW64 & System32, inside the lvlib files that are used... basically anywhere where I could paste the DLLs.

  I have another DLL made by the same company which I call in a different section of the code, and they run perfectly while being just included as usual to load in the application Builder (and stored in the data folder, as it seems normal)

  I use the same machine for development and deployment.

  I built all of the Subvi who calls the functions of the library with tools-> import-> Library (.dll) shared

  It's the Subvi (void) [Init] which gives the error. I missed a toplevel VI image because it is a very standard call of this sub - VI

  

  I don't know what I can do.

  Any help would be greatly appreciated

  I'm under Labview 2014 SP1 (32-bit) on a 64 OS Windows 7 bits (as a workaround for a problem of unrelated pilot)

  Thank you!

  There are other DLLs in the library driver instruments. Most likely, they are indirectly used by the DLL, you go from call library node. They must be present in the same directory as your executable file. When you run the VI in the development environment LabVIEW adds project directory and perhaps the directory lvlib to the search path that Windows should search for the secondary DLLs into an executable file, but that does not apply.

• Error 1097 while controlling a Velmex

  I use a configuration of Velmex two axes to quickly move a probe quickly into and out of a flame. The Velmex is supposed to move the probe in the flame, let it recueillir collect data, move it out of the flame, and then repeat the process at a slightly more advanced position inside the flame. After that is finished, the second engine step by step is supposed to back the probe and the process begins again. In the middle of the routine, however, it no longer works and I end up getting error 1097. Why is that happen?

  This is the VI for reference.

  Nothing to do in this VI and DLL. On the one hand a DLL is just a compiled code, so there is not much to see from the only DLL. Also a DLL contains no other information about how it is supposed to be called. The implementation of the pilot is terrible with all calls in a single VI and Boolean values a half-dozen select which of them to call. He deserves perhaps a 6 out of 10 for a feature, a style 1 and 2 for cleanliness.

  Without this driver DLL API documentation, there is absolutely nothing possible to tell about the accuracy of the CLN configurations. As simple as looking at the functions, there is always a chance that this configuration was wrong somewhere. Another less as being likely to cause is that the DLL itself is poorly written too. If the LabVIEW application is less for the quality of the driver DLL implementation, then I guess it would be easier to throw everything away and re-implement the pilot purely in LabVIEW.

• Create a DLL to read an Image using OpenCV

  Hi all

  I am trying to create a DLL to perform image processing using OpenCV. In the first place, so I try to create a DLL that can read an image and display it. But I encountered a problem when I call this DLL in LabVIEW.

  The error in LabVIEW that says: "error 1097 appeared to call library function node in the .vi DLL Image playback (Play).

  Possible reasons:

  LabVIEW: An exception occurred in the external code that is called by a node call library feature. The exception may have damaged the memory of LabVIEW. Save all work to a new location and restart LabVIEW. »

  Here are the steps I followed:

  1. download OpenCV2.4.9 and extract the files. Make changes appropriate to the Environment Variables to include OpenCV.

  2 start a new 2010 Visual Studio from Microsoft Project to create a DLL.

  3. Add a property sheet in the property manager to include the OpenCV library.

  4 change the DLL of playback picture .cpp code (Play) as it is in the attachment.

  5 compile to create the DLL of playback picture .dll (Play) file.

  6 create a LabVIEW VI to call the DLL.

  Attached are the related files: 1 .cpp reading Image DLL (game) 2. Read Image .dll DLL (reading) 3. Read Image .vi DLL (game)

• From a Void pointer in a DLL in Labview

  I have a DLL provided by a hardware manufacturing, I try to run in 2012 of Labview.  The first function gets a handle to a device connected to the USB port.
  CEDP i1d3Status_t i1d3GetDeviceHandle (unsigned int whichDevice, i1d3Handle * devHndl);
  i1d3Status_t is an Enumeration of error codes and i1d3Handle is defined as void * i1d3Handle.
  I wrote a wrapper for this DLL

  int GetDeviceHandle (int peripheral, i1d3Handle & handle) {}
  i1d3Status_t m_err;
  int error;
  m_err = i1d3GetDeviceHandle (device, & handle);
  error = m_err;
  error return;
  }

  I can get this working by the way the handle that adapt to the kind and maintain value.  The following function opens the device

  int OpenProbe (i1d3Handle handle) {}
  i1d3Status_t m_err;
  int error;
  unsigned char ucOEM [] is {0xD4, 0x9F, 0xD4, 0xA4, 0 x 59, 0x7E, 0x35, 0xCF, 0};.
  m_err = i1d3OverrideDeviceDefaults (0,0, ucOEM);
  if(m_err == i1d3Success) {}
  m_err = i1d3DeviceOpen (handle);
  If (m_err! = i1d3Success) {}
  unsigned char ucNull [] = {0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0xff, 0};
  i1d3OverrideDeviceDefaults (0,0,ucNull);
  m_err = i1d3DeviceOpen (handle);
  }
  }
  error = m_err;
  error return;
  }

  It works by passing the value of the handle returned from the previous VI as an I64.  There are several other functions to read the settings of the device that I know it is open and the handle is valid, but here's my problem.  The following function, I need to pass a pointer here is the code.

  int GetDiffuserPosition (i1d3Handle handle, unsigned char * pos) {}
  i1d3Status_t m_err;
  int error;
  m_err = i1d3ReadDiffuserPosition (handle (i1d3Handle), &pos);)
  error return;
  }

  This code works in VC ++ but not in Labview, I get an error of 1097 of the VI.  So passing the handle as an I64 will work as long as I do not pass a pointer with it because this code will not work.

  unsigned char GetDiffuserPosition (i1d3Handle handle) {}
  i1d3Status_t m_err;
  unsigned char pos;
  m_err = i1d3ReadDiffuserPosition (handle (i1d3Handle), &pos);)
  return pos;
  }

  I even tried to dumb down to the function

  int GetDiffuserPosition (int * i1d3Handle handle x) {}

  * x = 5;

  return 0;

  }

  and still no error of 1097.  Any suggestions would be welcome

  This excerpt must be the call library function correct node for the initialization and diffuser of playback functions. Give it a try? (If you are not familiar with the code snippets: this picture's code.) Drag it to your desktop to save a copy, and then drag it into a block diagram. You need resolve the path to the DLL of course).
