Sapera LT with CVI

• Sapera LT used with CVI

  Is that what someone has successfully used vision of DALSA, Sapera LT, with CVI library?

  Sapera LT supposedly has a C language interface.

  I have this poster in the forum of machine vision, but he seems to be more a SW problem (if, indeed, there are problems) a matter of HW.

  In principle, any standard interface of C (C89) should work with CVI I think... If it's for a framegrabber DALSA, or anything else.

  I was just curious if anyone had tried this specific thing, and if so, how it worked.

  Thank you

  Menchar-

  It turns out that you can use Sapera LT with CVI 2009.  You use the api 'base' which is an interface in ANSI C with the export header file and import for the DLL library is involved.  During compilation, I found 6 #defines which were redefined to somehow - the limits they were constant max on the different types of integers.    It seemed the stuff of limits.h, but it wasn't - I never figure out how or where he defined twice, so I just #undef had these just before the place where was held the redefinition and the problem disappeared.

  I was unable to use the framegrabber as a "camera" (peripheral), I used as a 'framegrabber"and loaded separately from the configuration files CCA and .cvi instead of a camera (.ccf) configuration file.  I have hooked up to a simulator CameraLink and grabbed a focus, then he wrote on the disk.  A close inspection of the data showed that it was seizing everything is OK.

  I used the 1.5 LT Sapera 7.0.0 and X 64 driver version.

  So I feel pretty good about this so far.

• Performance of CVI 2013 SP2 with CVI 2015 - Windows XP problem

  I see that XP isn't an operating system in 2015 of the CVI.

  Most of our PC are Win7 now, but we have some legacy units which require XP due to a limitation of external controller processor.

  Is is possible to generate executables in 2015 CVI which will work correctly with the runtime of 2013?

  Alternatively, CVI SP2 from 2013 and 2015 CVI co-exist on the same PC development?

  I would not get stuck with CVI 2013 SP2 for the future just to maintain a few predictable XP-based PC.

  Hi Shr,

  I recommend reading through this community's message: https://decibel.ni.com/content/docs/DOC-23955

  Essentially, you can develop a code in CVI 2015 but set the executable to run on previous versions of the Run-Time Engine. Note that the older version of the RTE of Side-by-Side CVI is 2012. You can indeed install previous versions of the CVI on the same computer. The shared runtime will be set to the latest version. Other versions will be side-by-side. The code is not guaranteed to work with previous versions of the RTE so be sure to test the code locally before moving on to another computer.

• Warning of 'Empty Declaration' ShObjIdl.h with CVI 9.0

  Just installed CVI 9.0 and now my project generates a warning of 'Empty Declaration' in ShObjIdl.h on line 1330

  I am including shlobj.h to support the use of SHGetFolderPath() and shlobj.h consists in turn ShObjIdl.h

  I think I have the same options as before compiler with 8.5.1.  I note that there is a new version of the SDK with CVI 9 probable factors in the explanation.

  Is this a cause for concern?

  Oops. It seems that I did a copy/paste error in this post, and Ian never called me on this subject. As I said, he must add a #define, not a typedef:

  #define tagSHCONTF shcontf_dummy {shcontf_dummy} shcontf_dummy_typedef; tagSHCONTF Enumeration
  #include

  Sorry about that.

• Web server with CVI

  Hello

  I want to know if it is possible to create a webserver with CVI so that I can connect my application and see the data with internet Explorer?

  Backround: we run a CVI-application on a computer within a network. On this computer, collect US data from different systems and publish these data in a sign of the CVI. Users who want to see the data, connect to the computer with a remote control software.

  Now, we wondered if it is possible to create a web server with CVI. And if the user cannot see the data on his computer using internet Explorer.

  In the forum, we found a few messages very old. Are there new items on this subject?

  Thank you

  Oliver

  As far as I know that it is not supported at the moment.

  And there is the suggestion of product requiring a few laurels ;-)

• Alignment of memory with CVI 2013 problem

  Hello

  I just installed 2013 CVI from CVI 2010 and opening my old projects, I'm in trouble with the alignment of the memory.

  Not in all the projects that I opened, I get the problem, and I'm quite confused about this.

  I used to keep in line with the limits of 1 byte of memory and I have thousands and thousands of saved file with this method.

  I have prepared a very simple project (attached to this post) to illustrate the problem, consider that the result would have been with CVI 2010 'occupation of 5 bytes.

  Hello

  I found the problem, there's a semicolon that follows the directive of preprocessor #pragma pack (1), and it causes the pragma is ignored.

  Remove the semicolon, everything works fine.

• Executable built with CVI 8.1 error-5093, the analysis library is not found

  Upgraded to 8.1 Labwindows/CVI of Labwindows/CVI 7.0 development machines. An earlier application was built using the ICB 7.0 and installed on a test computer. The same code built with CVI 8.1 is any error during execution of the function stdev, 5093 error code has been generated. (From analysis.h: LibraryNotFoundAnlysErr =-5093, / / the analysis library was not found.) Tried to build a facility with 8.1 and installation on the test computer and application errors still executing the stdev function. Back to the same application, but built with CVI 7.0, it works fine. Am I missing something with the build in 8.1 options? Or is it something in the workspace or project? Please notify. Thanks in advance

  Hi Tommy,.

  In CVI 8.0, the implementation of the analysis library has changed a static library that is linked to your .exe in a DLL that must be loaded when running. If you rebuild your source code and you want to deploy to another machine where the CVI environment is not installed, then you must re-create an installer in CVI 8.1 distribution, so that he can pack the analysis as well as your program library.

  You can confirm whether the analysis library is installed by searching for C:\Program NIUninstaller Instruments\Shared\Analysis\nianlys.dll in your target machine (although it is not enough to simply copy this file manually).

  When you create an installer in the CVI, be sure that, in the tab drivers & components in the dialog box change Installer , support of analysis element under the Group of LabWindows/CVI Run-Time Engine is checked.

• With CVI to transfer files to cRIO 9066

  Hello

  I'm trying to copy files to a directory on a cRIO 9066.

  The method I use is to map a drive in Windows 7 and I want to copy the files with the CopyFile function in CVI.

  The reader is defined as \\ni-crio-9066-030c6bf1.local\files (I also tried http://ni-crio-9066-030c6bf1.local \files).

  With this method I can transfer files on this disc with the CopyFile function, but the transfer rate is extremely slow.

  For a 300 KB file, it will take about 25-30 years.

  During this time, my request is breaking, there is no more values in the controls or the UIRs until the copy is complete.

  I tried to disable 'Automatically detect settings' in Internet Explorer in tools > Internet options > LAN settings > connections as I've seen in a knowledge base (http://digital.ni.com/public.nsf/allkb/4EBE45E8A816B19386257B6C0071D025).

  The copy is much more rapid 1-1, 5 sec but I have a few failures of transfer. Windows told me that the transfer failed in a popup, the file in the cRIO is a file of 0ko (and CopyFile returns an error).

  In the knowledge base, they warn about the failures of transfer but I was hoping to get an error code in the CopyFile function.

  I also tried to run cmd.exe copy 'name of the source file' 'target file name' with LaunchExecutableEx but I got the same results.

  I'm in a dead end for now.

  Do you have any idea how I can transfer files between CVI and the cRIO?

  PS: I tried the WebDAV protocol in Labview and it seems fine with that (good transfer rate and no failure of transfer). But I did find this library in CVI.

  Thank you for your help.

  I'm sorry for my late reply.

  I managed to send files in the cRIO 9066 via FTP.

  I installed 'Legacy FTP Server' on the cRIO and I used the FTP API in CVI (proposed on the french forum and by the regulation).

  This solution works very well.

  I didn't want to use an external if possible API so I chose the FTP solution.

• How to call dll com APIs that range from the performance counters of less than 1 ms with CVI and always get less timer resolution of 1 ms

  Hello

  I've created a dll com in VC ++ using performance counters/timers to less than a millisecond.

  This is useful when you send a message to very high speed. (say 10 or more)

  This is done by the dll.

  When I use CVI to create a user interface, this dll runs at a fixed rate of 1ms.

  This slows down the application.

  I tried to use the same dll with VC ++ host and it works well.

  I need to check the registry setting to see if the useDefaultTimer is set to false or TRUE.

  (I'm not near the development PC) However, by default, it should be FALSE and I have no fidle with it.

  Veuileez post any suggestions you might have.

  Thank you!

  This problem is now solved for me.

  Just the highest thread priority in the dll.

  Thank you if you had the answer.

• Using measure computing library UL (device USB-1208FS) with CVI

  Hello

  I'm trying to implement the system of company Measurement Computing USB-1208FS (www.mccdaq.com) in our test software tool which has been programmed in Ansi C using the CVI compiler.
  To make the first steps, I am building an executable based on the Ansi C «DaqInScan01.c» example code
  While I have no problem with the compilation of the code, the linker complains with errors shown below. Although the cbw32.lib is registered with my project, ICB seems not to be able to reference the functions of the library.
  What I am doing wrong?
  Is there the CVI samples available to guide me in the first steps regarding this device?
  I use WinXP SP3, CVI is version 9.01

  Thank you for your support

  Hello IEE_newsoft,

  Looking at the screenshot you posted, a recommendation is to make sure that the header file and library with the same name, also have you been able to call the dll or lib successfully in another environment, IE such as visual studio to check there is nothing wrong with the files. Also look at this Developers Zone,http://zone.ni.com/devzone/cda/tut/p/id/3453 it shows you how use a third party dll of CVI and http://zone.ni.com/devzone/cda/tut/p/id/8503 shows you how you can use either dynamic or static linking to call your dll.

  Hope this helps

• Distribution with CVI 8.0.1 construction kit fails after installation of CVI 2010

  Update out of the newspaper:

  Adding files to install
  
  **************
  
  Internal error: A tool or the library returned an error. (Error code - 21)
  
  **************
  
  Error details:
  
  Error to the MDF API function: _MDFBuildDevPartMerger_Load
  
  returned nmdkLoadMergeModule code error 26152
  
  Final report of the error
  
  **************

  This happened earlier. CVI 7.1.1 and earlier versions than 8.0.1 (i.e. + 8.1.1) work.

  Any help would be appreciated.

  It turns out there are two different problems that arise in the CVI 8.0 distribution builds when you CVI 2009 or newer installed:

  1. Support for ActiveX container will not be included if you install the runtime in the application directory, or if you're not going under the grouping of LabWindows/CVI Run-Time Engine. In these cases, the ActiveX container merge module should be used and ICB 8.0 won't be able to find it.
  
  
  2. The merge module Instrument Driver Run-Time (instrsup.msm) and the Mesa merge module (NIMesaDLL.msm) cannot be moved to the application directory (which is the option on the Advanced tab that I mentioned in the previous post). This will result in the construction of distribution fails with the error you reported.

  To solve the first problem, I recommend the copy of C:\Program Files\Common Files\Merge Modules\ActiveX_Container.msm and rename the copy with a space instead of a line of underscore ("ActiveX Container.msm").

  The second question has no easy workaround. If acceptable for your use case, I would say either making the performance overall installation (by unchecking the option in the Advanced tab) or removing the CVI build runtime of your distribution. In the latter case, your application would be based on an already mounted overall CVI runtime engine.

  If any of those who will work for you, I can get you copies of pre-2009 instrsup.msm and NIMesaDLL.msm that you would have to manually exchange and out with versions in your common Files\Merge Modules directory whenever you have need to build this distribution in CVI 8.0.

  I am sorry for these questions. Let me know if you need these older modules.
