• Programmatic access to the DLL import wizard

  Our company carries out a number of products and I would like to cut down time when working with the SDK. I am almost satisfied with the wizard import in 2012, but I would like a few things have changed. I have all the code ready to modify the wizard output DLL import with the script module, but if I could have automatically build and run the whole thing (possibly through a statement following command line generation in Visual Studio), which would save some hassle.

  It's not a big deal. I just wanted to speed up the process a little, since our format SDK does not change. We had a custom to our SDK before, VI generator but it gets 95% of the way, and the wizard did everything we missed and gets about 95% of the way there also. That, or I could try to convince my colleagues to accept the results of the wizard.

  For everyone trying to do the same thing, there is already a thread on this sort of thing on the LAVA, which basically says that you'd better do it by hand because it would take a lot of work from the cut. I guess I'll write a Sikuli script to automate the unofficial versions of SDKs.

• Message DLL import table

  Is it possible to import a message table resource in a DLL (or, more precisely, an OCX file) in LabView such as error dialog boxes will make account correctly the error codes returned by the DLL calls?

  Thank you!

  The only thing you can do with the dll is calling features, and with the ActiveX interface, you can access only properties and methods. Maybe you can create a function to return the error based on the error code string?

• RT - error import dll

  Hello

  I am trying to use a dll I wrote on a PXI + RT

  I have compiled the dll using visual studio express 2010 on windows vista. Import and the dll under labview on my workstation works fine.

  but when I try to load the program on a PXI + RT I get a bad import error.

  The use of the auditor of dll RT (version 2009 and 2011), I see 25 bad msvcr100.dll imports and kernel32.dll. Some of the functions I can not import correctly are:

  DecodePointer, DecodePointer, CreateEventW, CreateSemaphore, etc...

  I am new to using the dll in LabView and I wonder if I missed something or if I'm doing something wrong...

  Can you help me?

  Thank you

  You cannot directly call Windows functions but certainly C runtime library functions. And C in Visual C runtime library is essentially built on the Windows API. So if your DLL connects with the Visual Studio C runtime somehow you pull various imports in your DLL. Indeed imports you listen to are mostly located in msvcr100.dll which is the C runtime library. Even if you don't make use of any C-runtime function that is, Visual C still shoot in the C runtime references for his start-up code for the DLL.

  In a normal Windows system you can simply install the installer distributable runtime for versions of the libraries C runtime that corresponds with your version of Visual Studio, but in the real-time system that is not a real option as each newer runtime depends on new similar Windows API. Of course, this is NOT intentional (ha!), but simply in the interest of all users like the new Windows APIs automatically means more security, right?

  OR supposedly installed a specially designed DLL MSVCR who very probably, they build themselves to work for kernel real time installed on a system, but that is based on an earlier version of the runtime C MS (and I do not know what Treaty of Redmond licenses should be allowed to do, but I don't know there are many legalize involved there). Basically what wants to say, you must use the version of Visual Studio that is compatible to the runtime library C MS available on the target in order to create shared libraries, real-time search just a msvcrxx.dll in your system in real time and you can see on the xx, what version that should be (except that the version numbers are not as simple to match more but 7.0 was VS 7 7.1 was VS 2003, VS 2005 was 8.0, 9.0 has VS 2008 and VS 2010 10.0 a). Alternatively, you can try to find an installation of Visual Studio 6.0 with SP 5 and compile your DLL. This DLL will use the Microsoft internal standard C runtime MSVCRT. DLL which avoids the whole versionities to the potential cost of disorders of DLL hell.

  Another option could be to use some based MinGW compiler toolchain. They usually use MSVCRT. DLL too much for their C runtime binding. Another option is to install the Windows Device Driver Kit or how it's called these days. The command line compiler toolchain that comes with it, is also linked to MSVCRT. DLL instead of a specific VS runtime library.

  Trying to trick the new version of Visual Studio by using MSVRT. DLL is rather an exercise in vain that I had to discover in the many hours spent on this. My current approach is to use VS 6 to create DLLs in real time, since I have available, but you can not buy more or download it from Microsoft.

• Problems to make an executable VI from a DLL

  Hi people,

  I have 2 of the DLL, the first (rfid.dll) is imported into labview and contains some 55 functions. 1 of them has an internal memory management and too complex to work properly. So I have a second (wrapper.dll) dll that contains a simplified access to memory. However, on the second dll import, I get

  No executable VI
  The VI is not executable for one of the following reasons:
  1. the shared or a file-dependent library is not installed. To make the executable VI, you must install the shared library and all files supported on the computer on which you run the VI.
  2. a required custom control may be empty or cannot be found. To make the executable VI, manually update the custom control.
  3. the VI contains a parameter with an unsupported data type. To make the executable VI, you must replace the cluster indicator or empty the wizard generates a control that uses the data types supported.
  Retrieve attached RFID Radio list Wapper.vi
  test.VI

  Note that test.vi is not either executable, if I test function in the second dll, then test.vi is executable. It would seem that the second dll is unable to locate the rfid.dll.

  Any help please.

  Robert

  It seems that labview can solve the DLL using the DLL using the DLL

  My first rfid.dll used 2 other DLL that were in the path given, that has been resolved and I was able to import.

  The second wrapper.dll used the rfid.dll and it appears that the produced DLL in the same way, that he was unable to go to the next level.

  I fixed it by copying all the DLL in that I needed

• What is the right method to access the functions in a DLL compiled with a target of THIS (Arm)?

  I tried without success to access functions in a DLL that is meant for Windows CE.  My Labview application objective is a touchscreen the arm-based device.

  All, thank you very much for all your help.  I was still unable to find a method that did not produce an error when compiling... calls for a vi or a C file to be included.  (ex: [feature] is a missing file vi or C).  I also tried including the import library for the DLL, as shown above in the email from Paul, but I still received the same error.  This has been a problem for me, while testing with Win32 non-targets... in this case a device of THIS 5.0 touch screen based on the arm.

  However, I found a solution feasible and quite simple:

  Instead of trying to register the import library DLL as a file depending on the vi, I changed to build a DLL (and associated import lib) to build a static library (.lib) and included while .lib file as a dependent in the build specification.  This had the effect of linking statically, object code rather than wait for the vi compiler to compile the C source code or link a DLL import for a non-Win32 target library.  It is also not necessary to include an additional step in the installation of the DLL on the target device.  The library, I created is just a simple interface to another DLL already on the target device, which had struggled to interface directly to Labview.  Given that it is only a role of simple interface, this solution of library static woked well because it was not essential to have its available as a separately scalable DLL functions.

• Problem of driver DLL StepperBee +.

  
  

  Try replacing the header with the following text file (for unknown reasons, the forum won't let me download it).  Function calls use simple types, there is a good chance that the DLL import wizard will be able to manage by using this header file.  For some reason, the Import Wizard of DLL, at least in 2009 of LV, imported bool as a char * instead of int, so I replaced the bool with ints as well.  See if it works.

  // Header file for use with stp.dll
  
  int InitStp();
  int RunMotor1(int steps, int interval, int direction, int outputs);
  int StopMotor1(int outputs);
  int RunMotor2(int steps, int interval, int direction, int outputs);
  int StopMotor2(int outputs);

• use a C++ DLL in LabVIEW

  I have a DLL that has been written in C++, and the typedef in C++ code is defined as:
  CY_BUFFER
  Definition
  typedef struct
  {
  int size;
  char * data;
  } CY_BUFFER;

  There is a function that should return the number of version as shown below:

  C function
  Version CY_INT (CY_BUFFER * buffer);

  A sample of code C to write to call the DLL is listed here:
  Example in C
  #include "cy_runtime.h".
  const int CUDA_DEVICE = 0;
  If (Initialize (CUDA_DEVICE)! = CY_SUCCESS)
  Returns - 1;
  Buffer CY_BUFFER;
  If (init_buffer(&buffer)! = CY_SUCCESS)

  If (version (& buffer)! = CY_SUCCESS)
  Returns - 1;
  If (free_buffer(&buffer)! = CY_SUCCESS)
  Returns - 1;

  I have built wrapper LabVIEW using the DLL import wizard, but may not know what I have to do. I read the pointers to C/C++ dll dereferenciant in LabVIEW, but I do not understand how to use. Y at - it someone who can point me in the right direction here.  I can't edit the C++ DLL, but I don't know in theory, only the types of data, I just may not know what the wizard trying to do when he created the GetValueByPointer VI code it generates automatically.  If its C++, do I need to not use the wizard at all and create from scratch?  Any help would be appreciated gratefully.

  In addition to what Nathan said, you probably have an alignment problem. C compilers tend to align the elements in a struct to their inherent normal size. This means that the char pointer will be aligned to 4 bytes when you use LabVIEW 32 bits and bytes 8 when you use LabVIEW 64 bit. Now since the DLL also provides the init both the free function, this makes things a little easier. You can simply create an array of 4 integers from 32-bit bytes, pass it as a pointer to array to the function init() and version() free() and the only thing you need to do before release called an additional function of MoveBlock() where you adjust the offset in this table for the number of bits of LabVIEW.

  

  This involves a number of things:

  (1) your struct is indeed using 8-byte alignment, which causes the pointer to the byte offset 4 in for 32-bit LabVIEW and structure at byte offset 8 for 64-bit LabVIEW. Are you of any changes by using 64-bit LabVIEW, now that you have these 4 additional elements of the cluster between the size and the pointer?

  (2) in fact, the size in the struct element specifies how much data is in the buffer tank.

  And for the functions of the DLL error handling was completely omitted. To match the C code, you have shown that you should always check the function returns the value too before continuing.

• DLL, interfacing with which coexist value and reference types

  Currently, I'm working with a supplied DLL.

  I have header files and everything and the DLL import wizard does a decent job of importing DLL functions but there are certain types of data that cannot simply be dealt with.

  The DLL requires the use of a data type that is a structure with data reference and value types.  I could theoretically replace the references by simple U32s, but much of the information required in the data is in the data referenced by the pointers structures.

  How can I do to implement this light how do I have to be able to transmit data to the DLL in its original form (value and reference types).

  I have something like the following:

  struct point {}

  Int device,

  * The point then

  * Previous item

  * Data Datastruct

  }

  I downloaded the Microsoft WDK, CVI and Visual Studio 2008 available.  I'm not very experienced in this end of things...   I will dispose of Structs with pure value types, but how do I get the data in reference types?

  I strongly suspect that I need a wrapper DLL, but how is the best way to go about this?

  Shane.

  Shane,

  It's always a problem when you use a DLL.

  If you do not have the sources of the DLL, you must trust the description of it.

  (Or you will have to disassemble to be sure, which is forbidden in most cases )

  If (in your case), the linked list is handled elsewhere than your Labview code, you will get in trouble. (Added, deleted, or modified items)

  I don't know your DLL. But usually the data is stored inside the DLL. For example, I have a DLL function that reads a counter from a DAQ hardware. If I reset it (on its reset settings), it sends back the nuber of counted events. This DLL must not be initalized.

  Other hardware DAQ I use must be initalized using its DLLS before you read all the values.

  It all depends on the implementation of your DLL.

  You have a detailed description of your DLL?

• 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

  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.

• Just bought Satellite C660 and need some information please

  I just bought a Toshiba Satellite C660 1 t 1 and have some important questions, I would like to meet you please. I have looked for answers, but could find nothing specific.

  The first question I have is that when I turned on my new laptop and installed Windows 7, I noticed he had partitioned my hard drive to 500 GB in two for a 232 GB C: Windows and a 232 GB data D:
  I was wondering if there was a setting that I had missed during my first installation of Windows 7 where I could change the size of the partition? As on a previous Samsung Netbook, I could choose how much space I wanted to a backup disk, but does not remember seeing a similar option on the Toshiba startup options? If someone could confirm it please that you can't change the size of the partition to installation of commissioning, it would be a relief, because I am worried, it was my fault the score is so great.

  The second I have is that when the driver updates are released to update my driver graphics and any other material, which is the best piece of software Toshiba I should use to find and update the material? As there seems to be a lot of them pre-installed and they seem to all updated software?

  The third question is: are there specific pieces of software toshiba which should start up when I start my PC? As I will try to stop programs unimportant all begin when starting my new laptop until reduced startup time.

  Finally (sorry for so many questions) someone could explain to me why its so important to create a "recovery disc" and why it seems that I must do this as soon as possible? I'm really not at all, or the importance to create one as soon as you get your new laptop.

  Thank you very much for all the help that I tried to find answers to these questions and noticed that everyone on these forums seems to be very competent and friendly :)

  Aaron Hello and welcome to Toshiba support forum

  At first, I must say that you are doing very good. It is best to ask first before you start to experiment and screw something up. A lot of people changing all implement and later wonder why some software stuff don t work anymore.

  I have a little experience with Toshiba and will try to help you. So let's go.
  > I was wondering if there was a setting that I had missed during my first installation of Windows 7 where I could change the size of the partition?
  When you start a laptop for the first time be preinstalled recovery image will install and you will have a laptop with factory settings. This HARD drive partitions are standard. After the first start the most important is to create recovery DVDs. After having done that, you can do with your computer laptop all you want. You can delete the partitions. Change the ability scores, install OS clean, but you will be able to install the original Toshiba recovery image using this disc. It is very important.

  Of course, you can install os using HDD Recovery mode - http://aps2.toshiba-tro.de/kb0/HTD1303440001R01.htm
  In general, you can change the structure of the partitions but it may happen that there will be problems to start HARD drive recovery after doing this, but if you create recovery DVDs there is no problem for you.

  > The second I have, is that when the driver updates...
  In General, you should not install updates, especially not for Toshiba tools and utilities. My advice to you is: don change well equipped with operating system. What can you possibly update is display driver, but please use driver Toshiba only.

  > are there specific pieces of software Toshiba which should start up when I start my PC?
  Much preinstalled stuff slow startup and notebooks in general performance. So that you can disable some startup applications (MSCONFIG > startup) or even to remove them from the system. For example, you can remove Tempro, information tool product Toshiba, remove an application preinstalled antivirus and install something better like Avira Antivir. At startup, you can turn off the zooming utility, application, Adobe Reader, Google update, check laptop Toshiba webcam and so on. I turn off even more things and leave just more important tools.

  > could someone explain to me why its so important to create a "recovery disc" and why it seems that I must do this as soon as possible?
  I hope that I have answered this already, but here is the content of the Toshiba Recovery callback:

  * Important INFORMATION *.

  * your system is equipped with a hard drive recovery system. If you need to repair your computer in the restaurant to the original factory condition, you can do it directly on the hard disk (press F8 when you start your computer, choose "Repair your computer" and follow the instructions in the menu) or create a bootable recovery for this fin.* drive carrier

• How to use fft2d labwindows

  I would like to use the FFT2D function in the LabWindows CVI 8.5 analysis library.  Unfortunately, the help section is not very informative: the input signal to transform and fft 2D returned are the two type of void pointer.  I would like to pass an array of type double, and I expect an array returned by a complex data type, possibly a structure with a real and imaginary component.  There is an example of 2dfft in the directory/samples/analysis, but in this code they essentially rewrite the fft algorithm and use global variables to get the data.  What is the right way to call this function?

  As an alternative, I tried to use FFTW .dll file.  This package comes with a .dll file and .def files, but no library file (.lib).  On this page http://zone.ni.com/devzone/cda/tut/p/id/3341 the following statement is made: "If you don't have the DLL import library, you can create one using the LabWindows/CVI tools provides" but it fails to tell you how to do this.  So how is - a generates the .lib files .dll and .def file in LabWindows?

  Thank you

  CVI can generate a .lib for a dll file, if it has an associated .h file. On 7 CVI, open the .h file in the Editor window, and then click the Options menu item. You see a line "DLL import library to generate" - click here and follow the prompts from there.
