• is it possible to tell me how I can make program in labview that take black and with image pixels and give the coordinates of black or white pixels again to me.

  Hello everyone

  is it possible to tell me how I can make program in labview that take black and with image pixels and give the coordinates of black or white pixels again to me.

  It depends on the image and the module LabVIEW available to you. LabVIEW can open bitmap and png files and convert them into tables: if it's really a monochromatic (depth of 1 bit) you get a table 2D boolean, T for white, F for black. Just look at the index of the item to its details (don't forget that LabVIEW does not use the order of rows and columns, so you must transpose and reflect the table). If you have a 24 bit bitmap, the table will contain the color in hexadecimal synthesis (000000 for black, FFFFFF is white and so on); Yet once, you simply check if the element of the array correspond to your requirements and get its index.

  With the vision that you module con open other pictures and perform advanced on them without convert them into tables. Anyway, you can just type the extension of your image using LabVIEW and see what you get.

  Here is a code snippet to open a monochromatic image

  

• How to collect data on the programs of LabView and VC ++ at the same time?

  Hello

  There are two programs in LabVIEW and another is in VC ++. The two programs to collect hardware data.

  Therefore, for the experience, it is necessary to begin to collect data at the same time and lag must be

  less than millisecond (it is essential for the experience). How can this be achieved? BTW, I'm new to LabView.

  I think on the use of network socket to get the message for both applications.

  I was wondering if there is a better way.

  Thank you.

  You do not say if two programs access the same material, but I guess not. Because if they did, you probably get conflicts when the two programs try to access the same material at the same time.

• I am facing a problem with the beep.vi. I have a DAQ program, which acquired the signal and compare it to a threshold value. When a signal is out of range, a Visual and sound alarm has occurred. I use the VI beep.vi to generate the sound.

  I am facing a problem with the beep.vi.  I have a DAQ program, which acquired the signal and compare it to a threshold value. When a signal is out of range, a Visual and sound alarm has occurred. I use the VI beep.vi to generate the sound. Everything works fine except the sound alarm. It gives the table 1 d of type mismatch. I tried to fix this by placing it in a box structure. But it still does not work. If someone could help? Please find attached my VI. Best wishes to all visitors to the Forums of Discussion OR.

• TCP data labview n/b and c ++

  Hello

  I am trying to establish connection TCP LABVIEW n/b and program C++. Server is established in C++, while the client is implemented in labview. Even if the connection is established with customer success and the b/w Server, both are unable to correctly understand send/receive data between them. For example if I want to send a send_array of type int to the server, I use the 'send' like that standard WINSOCK function:

  Send (AcceptSocket,(Char*) send_array, 129 * 4, 0);

  but when this table was made by the client in labview, it shows unexpected values. As a customer, I used 'data simple client.vi' with a change as Envoy (129 * 4 bytes) data size has been set, only TCP read has been used.

  Same problem exists if I send data from client to server.

  Kindly help me

  Best regards

  It's probably a problem of edian big/small. If you use the flatten/Unflatten of string functions, you can specify which one to use.

• broadcast another program through labview

  Hello

  I have a question

  is it possible to broadcast another program through LabVIEW?

  for example, I run a program in my computer, is it possible to have the remote people to look at how the program runs through the Internet and LabVIEW?

  Thank you

  Cynitha

  Yes and no.

  Yes - if you are showing them how to use a VI that you configured as a server, they can watch using remote façade. There are also (limited) ActiveX controls that allow you to use external applications in LabVIEW, IE: Word, Excel, WMP, etc.

  No - if there is no involved VI, you want to just show them a random program, you can simply use Remote Desktop connection. Click Start > programs > Accessories > Remote Desktop Connection, its fairly explicit use.

• LabVIEW Analysis multicore and empty matrices in applications Applications Toolkit

  As well as several other toolkits, "in 2015 the analysis multi-core and Sparse Matrix Toolkit moved to the LabVIEW tools network."

  In previous versions of MASM tool, a runtime engine was necessary to the execution of applications applications used the Toolbox. With the move to network tools it seems not be any support for applications applications.  Builds work very well, but can not run on systems that do not have a LabVIEW development environment and the Toolkit of MASM installed.

  Everyone has tried to build a LabVIEW application in 2015 using analysis of Sparse Matrix Toolkit and LabVIEW Multicore?

  I contacted my local support staff and applied for online support, but until now I'm stuck on the first level of the AE group, and I really need to talk to a developer of the tool of MASM. Is there a developer reading this forum tool? Could someone at OR who reads this please pass it on to a suitable developer?

  Thank you!

  Matt

  Matt,

  We have published the installer of the MASMT runtime on the next page of the LVTN

  http://www.NI.com/gate/GB/GB_EVALTLKTLVMULTICORE/us

  You can click on "Download of FTP" on the section 'Download NOR LabVIEW Multicore analysis and Sparse Matrix Toolkit Run-Time Engine' to get the Runtime setup. We will know if you encounter any problems. Thank you!

• Space required on target RT for LabVIEW Control design and Simulation

  Hello

  I want to run a DLL file on an RT target using LabVIEW Control design and Simulation, but I'm not sure of the required amount of RAM on the RT-target. My RT-target options are respectively cRIO 9002 and cRIO-9004 with 32 and 64 MB of RAM. Is this a sufficient amount of RAM to run the simulation? ¨¨

  Thanks in advance

  This will depend on the size of your dll, the size of the rest of the code, you can create other necessary drivers/modules, memory use when your application runs, etc.

  9002 and 9004 have not a lot of RAM on them and the minimum software installation to run a control application Design & Simulation (CD & Sim) will take around 22Mo of it (the majority of RAM available to the 9002). It would be possible to run your application on these two controllers if you keep it small but it will depend on what you want to do.

• In Labview 8.6 and MAX, I can change a scale for a voltage read the string in a task once the application has been built and installed.

  In Labview 8.6 and MAX, I can change a scale for a voltage read the string in a task once the application has been built and installed on a second PC. Where's the info of the scale which is held?

  Hello

  Once you have built your VI and compiled into an executable file and deployed on another machine, it essentially becomes a file read-only, which means that you will not be able to change the balance in this deployed application.

  Kind regards

• Build the program in LabVIEW 8.6

  Hello

  How can I build a program in LabVIEW 8.6?

  Then, you use the application builder.  It comes with the edition of professional development of LabVIEW, or an add-on to the Full Development Edition or the basic edition.

  You must create a project file with your VI.  Search the help of LabVIEW for 'building a stand-alone Application '.  Also search the forums on the subject.  It is repeated several times before.

• Use autoit in labview to optimize and define the upper window does not?

  

  You start using autoit and most window control commands the excellent work, but I can get WINSETONTOP AND WINSETSTATE functions work.  Everything seems good but keeps showing missing terminal wiring.  I checked to see if I could change my writing, but is not available.  Also tried using SW_SHOWMAXIMIZED and SW_MAXIMIZE properties.  I join the Labview 10 code and, hopefully, a snop shot here.  Can you send me an example of work or provide details as to what may be the problem.

  Thank you!

  Shannon

  

  I have it.

  You were right, necessary to the empty wire CHARAC StrTxt value to get rid of the error of wiring.  Use the node property as shown.  Not sure if that's how it is supposed to be coded, but that's the only thing that has worked so far.

  StrTxt is optional for others that I use.

  It seems to work very well.

• LabView 8.5 and 2010 on the same computer running XP?

  Is it possible to install two version 8.5 and 2010 on the XP machine? And then work on some projects in Labview 8.5 and on other projects in Labview 2010 without a conflict?

  What about device drivers? What version of DAQ driver will work in both versions of Labview?

  Thanks a lot for any insite.

  Always install older versions first. Some SDK don't play well with several versions of LabVIEW. With regard to the acquisition of data: http://digital.ni.com/public.nsf/allkb/F4E76EC05118F72D8625773000672298
