• WebService in LabVIEW 2009

  Hi, I'm trying to start a Web as shown in the webcast service

  http://zone.NI.com/WV/app/doc/p/ID/WV-810

  I tried with the same kind of vi (the sum operation). The Web service is deployed successfully, but I can't access it even from the same machine. Is the address that I type in the address bar of internet explore

  http://localhost/math/sum/2/5

  I'm WebService Math I use windows 7, LabVIEW 2009. My project is attached.

  Thank you.

  Maybe you should try

  http://localhost: 8080/Math/sum/2/5

  The port of web services for LabVIEW is normally not the default port (80). It depends on your server settings.

• Narrow ARM of SPI VI reference works do not for me LabVIEW 2009.

  I use LabVIEW 2009 Embedded for ARM in collaboration with the Council of development of LM3S8962 and the MCP3008 10 - bit ADC chip. I'm trying to use the base screws of SPI to communicate with the MCP3008 - see the attached excerpt from VI to my current attempt. I can initialize the SPI reference, read two bytes of data from the ADC, but when I try to close the reference, the application crashes. If I am the narrow ARM of SPI reference VI in a diagram to disable, the program terminates normally, and I get to see my two bytes of data printed on the OLED. Any ideas?

  Thanks in advance,

  Stuart

  Thank you!

  Who takes care of the immediate problem. I really appreciated the quick response!

• Cannot bind to the shared object created with LabVIEW 2009

  I have problems referring to a shared library built from a LabVIEW VI under RHEL 5 with LabVIEW 2009.

  To illustrate the problem, I created a VI with a digital input and output that corresponds to a certain number. Then, I created a draft specification of build to create a shared library with a feature that makes use of this VI square. The shared object is created successfully (square.so).

  When I try to compile a test application written in C, that connects to this library, I get errors in the following link:

  cc  -I/usr/local/natinst/nidaqmxbase/include -I/usr/local/natinst/LabVIEW-2009/cintools build/square.so  test.c   -o test/usr/local/lib/liblvrtdark.so.9.0: undefined reference to `std::basic_istream >& std::basic_istream >::_M_extract(float&)@GLIBCXX_3.4.9'/usr/local/lib/liblvrtdark.so.9.0: undefined reference to `std::basic_istream >& std::basic_istream >::_M_extract(double&)@GLIBCXX_3.4.9'/usr/local/lib/liblvrtdark.so.9.0: undefined reference to `std::basic_istream >& std::basic_istream >::_M_extract(double&)@GLIBCXX_3.4.9'/usr/local/lib/liblvrtdark.so.9.0: undefined reference to `std::basic_ostream >& std::basic_ostream >::_M_insert(double)@GLIBCXX_3.4.9'/usr/local/lib/liblvrtdark.so.9.0: undefined reference to `std::basic_istream >& std::basic_istream >::_M_extract(float&)@GLIBCXX_3.4.9'/usr/local/lib/liblvrtdark.so.9.0: undefined reference to `std::basic_ostream >& std::basic_ostream >::_M_insert(double)@GLIBCXX_3.4.9'collect2: ld returned 1 exit statusmake: *** [test] Error 1
  

  Running ldd reveals that liblvrtdark.so.9.0 is used for the execution of labview.

  In order to investigate on what could be the cause of the problem, I have compiled the nidaqmx basic examples, and I don't have an error. Current running ldd as reveals that he uses liblvrtdark.so.8.2 for the view of laboratory, time of execution.

  My suspicion is that some components of labview are being compiled with gcc 3.4 while others are being compiled with gcc 4.1 (which is the default compiler in RHEL 5).

  Any ideas how I could fix the build errors?

  Thanks in advance for your suggestions.

  PS.

  I enclose a tar file with the source files and here are the details of the ldd:

  Hi mimi,

  I'm happy to report that I managed to get the code to work. I have included some of the steps I experienced the problem in case it might help improve the documentation or future generations.

  In response to your question about the "error 1" reported by do, it's just an indication that detected a compiler error (it probably resembles the return code of the compiler).

  The errors ' undefined reference... @GLIBCXX_3.4.9 "have been narrowed down. The generated labview shared library, the square.so, links to /usr/local/lib/LabVIEW-2009/patchlib/libstdc++.so.6 which is a symlink to usr/local/lib/LabVIEW-2009/patchlib/libstdc++.so.6.0.9. I decided to compare this version of libstdc ++ that included with RHEL:

  strings /usr/local/lib/LabVIEW-2009/patchlib/libstdc++.so.6 | grep GLIBCXXGLIBCXX_3.4GLIBCXX_3.4.1GLIBCXX_3.4.2GLIBCXX_3.4.3GLIBCXX_3.4.4GLIBCXX_3.4.5GLIBCXX_3.4.6GLIBCXX_3.4.7GLIBCXX_3.4.8GLIBCXX_3.4.9GLIBCXX_FORCE_NEW
  

  strings /usr/lib/libstdc++.so.6 | grep GLIBCXXGLIBCXX_3.4GLIBCXX_3.4.1GLIBCXX_3.4.2GLIBCXX_3.4.3GLIBCXX_3.4.4GLIBCXX_3.4.5GLIBCXX_3.4.6GLIBCXX_3.4.7GLIBCXX_3.4.8GLIBCXX_FORCE_NEW
  

  So libstdc ++ RedHat does not include a string for GLIBCXX_3.4.9.

  With this in mind, I was able to get my test application to compile using the version of LabVIEW libstdc ++ using the following makefile:

  .PHONY: all cleanCPPFLAGS=-I/usr/local/natinst/nidaqmxbase/include -I/usr/local/natinst/LabVIEW-2009/cintoolsLDFLAGS=build/square.so \        /usr/local/lib/LabVIEW-2009/patchlib/libstdc++.so.6 \        -Wl,--rpath -Wl,/usr/local/lib/LabVIEW-2009/patchlib/
  
  all: test
  
  clean:        rm -f test *.o
  

  When you try to run the application, I got the following error:

  ./test: error while loading shared libraries: /usr/local/lib/liblvrtdark.so.9.0: cannot restore segment prot after reloc: Permission denied
  

  But apparently, it's because of SELinux prohibiting the use of libraries shared with moving text.
  This can be disabled by running /usr/sbin/setenforce 0 as root.

  The test application now works!

  See you soon,.

• Switch Executive stops working after LabVIEW 2009 installed.

  I just installed LabVIEW 2009 and now Switch Executive 3.0 does not work.

  NISE open session vi returns 0 instead of the valid session ID. It does now with LabVIEW 8.6.1 too.

  Everything looks OK in MAX.

  Any suggestions?

  Hi Pirkola,

  I'll try to replicate that.  I understand it is a returned 0 for a session ID.  Is there an error returned as well?

  Thank you!

• Failed to retrieve the DIAdem DataFinder research data, using data-finder toolkit LabVIEW 2009

  I am facing problem to retrieve the DIAdem Datafinder data.

  At first, I developed this project in LabVIEW 2010. But because of a problem that I met in LabVIEW 2010, I thougth to work on the project in LabVIEW 2009.

  Then, I reused the project that I created using LV 2010 using option economy for the previous version.

  When I tried to retrieve the data from the tiara using data finder toolkit. I got a 305505 warning. Please see the attached message of Warninig.

  But I have not seen this warning while I was working in LabVIEW 2010 and also, I was able to get the data from the tiara.

  Please suggest me a way to solve this problem.

  Hi Nanda,
  There is a bug when using the SDK use in combination with DataFinder Toolkit 2009.
  This bug is already fixed in LabVIEW 2010 and use SDK 2010. But as you said there is another question in LabVIEW 2010, forcing you to LV 2009.
  I suggest you use LabVIEW 2009 with use SDK 2009 and DataFinder Toolkit 2009 and instead to use the "Waveform.vi results" to read the search results, I would recommend to use the screw storage. I spread your example VI and it attached to this message. You will still see the dialog box to search for "lvStorage.dll" but it will automatically disappear and the VI works anyway because in this case LabVIEW will find the dll itself.
  My extended VI uses the '_openWithRoot.vi' to open a file with a different use than CT or PDM. This VI is also described in the following knowledge base article: http://zone.ni.com/devzone/cda/epd/p/id/4181
  With LabVIEW 2010 use support has been enhanced and fully integrated in the standard palette of storage screws. So in LabVIEW 2010, you can replace the "_openWithRoot.vi" with the 'Open Data Storage.vi' standard but with LabVIEW 2010, you can also use "Waveforms.vi results" to read the search results.

  I hope this helps.

  Kind regards

• LabVIEW 2009 Crash when record for previous

  I'm having a problem when you try to save a VI in LabVIEW 2009 to a previous version of LabVIEW, in this case 8.2, but itseems crashing no matter which version I chose.  I've narrowed the problem down to this:

  If the vi contains a structure of event I get the following error: unrecoverable internal error: 'MemoryManager.cpp', line 547

  If I remove the structure of the event, she records very well.  I even go the error if I create a vacuum vi and drop an empty event on the diagram structure.  No control, no other code.

  Is this a known issue?  Is this a problem with my copy of LV?  Is there a solution?  Removal of the structure of the event in the present application is not an option.

  Thank you

  Rob

  So the solution is to save to LV 8.6, then open in 8.6 and save here to earlier versions.  It works, I have not tried to save 8.6 initially.

• MCB2400 LabVIEW 2009 Embedded build error

• LabVIEW 2009 linux crashes when editing a control, or a constant of resources VISA

  Linux crashes when I click on a constant resources VISA (block diagram) or control (front).  This happens on LabVIEW 2009 SP1 32-bit for Linux on CentOS (similar to RedHat 6.3) 6.3.  I have updated drivers VISA 5.1.2 and that did not help.  Thanks in advance for any ideas of five Linux guys out there.

  Hello Jason,

  My problem has been resolved with LabVIEW 2012.  To answer your question, LabVIEW would crash only trying to select another device in the list.  Thanks for your help.

• does not by default the tab control in LabVIEW 2009

  I have a tab control in my LabVIEW program. I put the default value of the three page tab control. In older versions of LabVIEW, when the program opens, it opens with the display of page three. Prefect! But now in LabVIEW 2009, it opens to 1 page view. I tried to adjust the default time and again, but it is enough to open with the display of page three. Looks like it's broken in LabVIEW 2009. (I know that I can get around that, but apparently botched when the program opens on page 1 and jerks on on page three.) And change the order of pages would break the code. I don't do that.)

  To make the solution more smooth, you can uncheck see the façade when called property of vi and show it programatically after that you put on page 3.

• In the connection wire diagram get blur while saving the VI in LabVIEW 2009

  Hello

  I'm using Labview 2009, and while I'm saving a simple connection of VI son become blurred. What could be the problem? Is it affect my program during the race?

  Go to tools > Options, select the diagram page and look for the section called Constant decline. If the CF for the sons of the box are checked, then this is probably the reason. You can uncheck the box, and this will not affect the way in which your code runs.

  If this isn't the case, you download a picture of what it looks like.

• Any LabVIEW 2009 Front Panel Gage displayed as circle deg continues 360?

  Any LabVIEW 2009 Front Panel Gage displayed as circle deg continues 360? I want to display a position of motor on the Panel before LabVIEW as a circle of 360 degrees. Is there a way to make the pledge appears as a circle of deg continues 360?

  dbaechtel wrote:

  Gauges and dials, buttons, none of them seem to be designed for continuous operation of 360 degrees. Of course I can set the scale of 0 to 360, but I can't get rid of the gap between 0 and 360.

  How to set up a pledge to show a continuous 360 degrees without a gap between 0 and 360?

  To change the gap, take the line high marker and move it to the desired location (in another origin, enter the low marker).

  Also, don't forget to wrap the raw in 0.360 rank if it falls outside. Here's a quick example (LabVIEW 8.0).
