Problems linking to DLLs

I am using DLL's that were written in C# to do database calls in my program. For some reason, I am having a real problem where the link to the DLL constructor keeps disappearing. I have to manually go back and re-link all of my constructor nodes and method calls. The DLL's are all kept in the same directory as the labview code. This occurs when using both the developement code and the compiled executable. We have double-checked all the DLL versions and verified that they are correct. After re-linking each of the DLL's the code works for a while, then it loses it's link again and has to be manually re-linked to work. It is not causing the program to crash, the writes to the database error-out and the program ceases to operate as expected. The problem is quite annoying, but worst of all, we can't figure out how to resolve the issue since we are not sure what is causing it. Numerous times we have gone to "tools/advanced/.NET Assembly reference" and removed everything and then re-added all the required DLLs back in. This does not fix the problem of the disappearing link to the Constructor. If anyone has ideas or has experienced this strange problem, please respond as we are at our wits end on this one...
Thanks

Have you registered your DLL? Sometimes these problems are caused by having a DLL unregistered or moving one that is registered.
Another possible problem is multiple DLLs with the same name, but I don't think that is your problem.
Hope that this helps

  • Problems linking Intel MKL in LabWindows

    I would like to use the Intel Math Kernel Libraries (MKL) in LabWindows.  However, I keep getting a linker error (undefined symbol when I try to call an MKL function).  The functions I want are the FFT libraries (DFTI).  I included the "mkl.h" and "mkl_dfti.h" files, and added them to my project as well.  I also tried adding the /Qmkl compiler flag when compiling using the Intel compiler.  This has become really frustrating, I don't know what's not added / included / not being linked.
    Has anyone use the MKL successfully in LabWindows??  What libraries did you add?  Thanks!
    Solved!
    Go to Solution.

    Wow - sorry about the lack of formatting in the previous post.  Here it is again:
    I am working on a 64-bit installation of Win7, but I am making a 32-bit project. I am using LabWindows as an integrated development environment and project builder. I have tried using both its native compiler and the Intel C compiler. In both configuration the linker is LabWindows.
    I am so far still only trying to use one function from the MKL, to test whether I have everything included and linked properly:
    DftiCreateDescriptor()
    I am including the following two header files:
    #include mkl.h
    #include mkl_dfti.h
    I added the following to my include paths:
    c:\Program Files (x86)\Intel\Compiler\11.1\054\
    mkl\ia32\lib
    c:\Program Files (x86)\Intel\Compiler\11.1\054\mkl\ia32\bin
    c:\Program Files (x86)\Intel\Compiler\11.1\054\mkl\include
    I added six .lib's to my project:
    mkl_cdft_core.lib
    mkl_cdft_core_dll.lib
    mkl_core.lib
    mkl_core_dll.lib
    mkl_intel_c.lib
    mkl_intel_c_dll.lib
    I have tried compiling with both LabWindows, and with the Intel C Compiler through the LabWindows external compiler support.  I have tried it with the following flags to the Intel C compiler:
    /Qmkl
    /Qopenmp -I%MKLROOT%/include
    I get the following errors now:
    FFT Test.prj(Release) - 4 link errors
     Undefined symbol '_mkl_dft_commit_descriptor_d_c2c_1d_omp' referenced in "mkl_intel_c.lib".
     Undefined symbol '_mkl_dft_commit_descriptor_d_r2c_1d_omp' referenced in "mkl_intel_c.lib".
     Undefined symbol '___kmpc_begin' referenced in "FFT Test.c".
     Undefined symbol '___kmpc_end' referenced in "FFT Test.c".
    An Intel MKL support person appears to have responded to my NI forums question, but they haven't been particularly useful yet.  The thread is open at:
    http://forums.ni.com/t5/LabWindows-CVI/Problems-linking-Intel-MKL-in-LabWindows/td-p/2210642
    I have a few questions.  First, are these .lib files static libraries, or lists of exported functions for the .dll's?  I think half of them, the ones that don't have "_dll" in their name, may be static libraries and therefore can have unresolved external dependencies (giving the first two linker errors).  Second, how do I add .dll's to a LabWindows project?  I have their directory in my include path (that's the \bin directory or the second include path I listed above).  Is this enough?  Finally, the Intel MKL responder in the forums.ni thread suggests adding a few .lib files to the linker, but I can't figure out how to do this in LabWindows.

  • SQORA32 driver could not be loaded. System error 1114: A dynamic link library (DLL) initialization routine failed

    I have an MS Access 2013 application that opens a connection to an Oracle database via an Oracle client.
    On occasion the application returns the following error when the ODBC connection is opened:
    Specified driver could not be loaded due to system error 
    1114: A dynamic link library (DLL) initialization routine failed. (Oracle in OraClient11g_home1, C:\oracle\product\11.2.0\client_1\SQORA32.DLL).
    This is an intermittent problem that is reproducible on several workstations (all running Windows 7 x64 with 32-bit version of Office 2013 and 32-bit Oracle client 11.2.0).
    Many times the ODBC connection is established without a problem
    Other times the connection can be established by closing then re-opening the application once
    Other times closing the re-opening the application several times does not help
    The same application is being run on several workstations and not every user experience the problem at the same time. The problem may be chronic for one user whereas another user experiences no problem whatsoever.
    All of the posts I have seen concerning this issue are for a persistent problem opening a connection and not an intermittent one. I am at a loss of how to diagnose this problem and would appreciate some direction.

    Hi Ross,
    This error message is Microsoft Data Link Error, this error occurs on windows when attempting to start a service or load a system driver but the DLL you loaded or one of its dependencies returned FALSE. It typically point to a system DLL file which is located
    in system32 and can be fixed by using the System File Checker tool. In your case, I suspect that it occurs due to a calling failure connecting to ODBC driver and it pointed to an error link C:\oracle\product\11.2.0\client_1\SQORA32.DLL which is hosted by oracle.
    If they are analogous, a “repair” seems to be helpful, However since we are not expert about oracle program I‘d suggest you check if C:\app\Oracle\BIN\SQORA32.DLL file exists on your machine and contact with Oracle first, I think there you can get more effective
    suggestion by other experts who familiar with design of Oracle database. Your understanding is highly appreciated.
    By the way, I searched for you and seems like you are not alone about this issue.

    You don't mention which specific version of the operating system that you are using - Windows XP, Vista, or 7 and whether you're using a 32-bit or 64-bit version.
    FWIW, kernell32.dll is a Windows system-level module, so it's possible that you have some corruption in your Windows installation which is preventing FM from launching.
    Also, 2Gb of RAM is a bit lean for FM.

  • Problem in creating DLL for a LabVIEW VI

    Hi
    I am facing problems in creating DLL for a LabVIEW VI. Previously i had no problems in creating DLL for the VI that transmits a message from serial port to NI - PXI 7831-R Reconfigurable I/O card (configured by FPGA MOdule). When i try the same VI with a customized port developed using IVI drivers i am not able to create the DLL. It gives me error as follows:
    Fatal Internal error: "datamgr.cpp", Line No: 1882
    Please somebody help me out to fix this error.
    Regards,
    Subramania Bharathi

    Hi,
    Thanks for your curiosity in replying my questions. I am really sorry for replying so late. Actually the problem was with the NI SWITCH 2503 functions. Actually i was multiplexing the channels of my customized serial port using NI Switch module. This switching is done before i start my communication. My VI follows a sequence as follows.
    1. Connect two channelss using Switch functions
    2. configuration of both FPGA and the customized port
    3. Transmit data from the port
    4. Receive it in FPGA.
    5. Reset the channels using Switch functions
    I never expected that the error was because of NI Switch. When i removed them from my VI i was able to create the DLL and able to create sequence successfully to run in the Testsand. And
    further i am using Switch Executive for swithcing the channels in TestStand.
    But now i am very curious why it posted me that error when i used my NI Switch function?? I tried to create DLL for a VI that switches two channels and i was successful. But the error occurs only when i combine i with my FPGA functions!! If you could trace out the reason, please let me know
    Once again thanks a lot for your support

  • Problems registering craxdrt.dll

    Hi Everybody,
    I am trying to get an application that makes use of Crystal Reports to build but have run into problems due to dlls not being registered on my build machine. The error message I get is:
    "The type or namespace name 'CRAXDRT' could not be found (are you missing a using directive or an assembly reference?)".
    This is due to a reference we have to craxdrt.dll (which is not registered on the build machine) in our application. The problem is that when I try to register the craxdrt.dll file with regsvr32 I get the following error:
    "The module "craxdrt.dll" failed to load. Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files. The specified module could not be found."
    I've had a look at craxdrt.dll with dependency walker, which lists the following dlls as missing:
    API-MS-WIN-APPMODEL-RUNTIME-L1-1-0.DLL
    API-MS-WIN-CORE-WINRT-ERROR-L1-1-0.DLL
    API-MS-WIN-CORE-WINRT-L1-1-0.DLL
    API-MS-WIN-CORE-WINRT-ROBUFFER-L1-1-0.DLL
    API-MS-WIN-CORE-WINRT-STRING-L1-1-0.DLL
    API-MS-WIN-SHCORE-SCALING-L1-1-1.DLL
    CSLIBU-2-1.DLL
    DCOMP.DLL
    GPSVC.DLL
    IESHIMS.DLL
    MFC71U.DLL
    I'm not sure if these are a red herring though as they appear to be Windows system DLLs for the most part, which I would not expect to have to redistribute with my application.
    Any help would be greatly appreciated as its starting to feel like banging my head against a brick wall trying to get this to work and getting nowhere.
    Thanks a lot for any help you are able to give!

    Hi Max,
    Moved your post to the Legacy SDK forum.
    Need more info, what version of CR are you using?
    And since the RDC is only supported in Visual Studio 6 I assume this is what you are using?
    Current version of the RDC packages up to CR XI R2 ( version 11.5 ) have redist packages available so don't try to deploy the runtime manually yourself, use the MSM or MSI.
    MSI should have all of the dependencies include, MSM will be missing ALL of the dependencies so you need to include them yourself.

  • Link a DLL with Step.Module

    I am trying to create a sequence file from a C# 2005 code using TestStand 4.0
    The flow of control is (without going into the coding details) :
    - create a step
    - create a sequence
    - add step to the sequence
    - add sequence to a sequenceFile
    - save the sequenceFile
    now, the porblem is that through this flow, a sequence file is created but i am unable to Link the DLL with the Step.Module . The adapter name is "AdapterKeyNames.FlexCAdapterKeyName" and step name is "StepTypes.StepType_NumericMeasurement".
    The manual reffers to the "CommonCModule.ModulePath" but i am unable to
    access CommonCModule ! The sequence file generated has no DLL and the
    expression is the default one:
    "Numeric Limit Test,  9 <= x <= 11"
    I need to:
    - link a DLL with the module.
    - Select a function from the DLL
    - Pass paramaeter to the mathod and get result ( some default values )
    - Set the expression
    - Set the low and high limit

    After reading Microsoft's description of the /MD linker option I'm assuming this is a bitness issue but with my limited experience on Windows I'm afraid I'm stuck. Note, I must build with /MD, it's a requirement. Any suggestions on what to do next?

    By the way, building with /MD is requirement imposed by 3rd party libraries I depend upon so removing it is not an option.An alternative still exists. Do not use JNI. Instead
    1. Wrap the target native code in an executable.
    2. Add a communication api.
    3. Test and debug as the executable.
    4. Run the executable via Runtime.exec/ProcessBuilder
    5. Execute the functionality via the communication api.
    No JNI in the above. Also no possibility that the native code can crash your VM. Even if the exe crashes you can add restart code to deal with it.

  • Problems linking libraries to device

    Hi, I am having a problem linking to a library, but only when I am building for the device. When I build for the device it has problems saying a number of functions that I use, their symbols could not be found. Building for the simulator it works just fine. For fun I removed the library from Xcode and tried to build with the simulator. The simulator then gave me the same error messages. Why can it find the symbols from the library for the Simulator, but not for the Device? I have tried explicitly adding the -dylibMYLIB.dylib to the other linking flags, but this did not work.
    Thanks,
    David

    I have found out that the reason is in my library. The simulator runs on i386 while the actual device will run on armv6. Also the iPhone library needs to be static. See this link for a very good explanation of it all. http://latenitesoft.blogspot.com/2008/10/iphone-programming-tips-building-unix.h tml
    Unfortunately my library fails to compile using these tips, does anybody know of a way to take an existing i386 library and recompile it for armv6? That way I could take the existing library I got from MacPorts and make it work for the iPhone.
    Hope the link helps a little.
