• data written in excel string is text rather than double when opened in excel

  I have the code that combines a time, many double arays string and some double rooms. Everything seems to work fine, except when I open the data file created in excel, the first cell after the time string is always a string and not digital. It is the first value in a double guard and all other elements in the array are correctly converted to numbers. Only the first element is misinterpreted. Is spoil other wise nice worksheet.

  Any thoughts?

  You already have the strings in a spreadsheet format.  Use Cancatinate strings instead of build table and then use the function Write Text File.  That could be the cause of all kinds of confusion for Excel.

• Shared data varying variable published network write error

  In my project in real time, on the VI host running on my Windows PC, I try to write in a number of published network shared variables.  All these write operations are successful (which means that I can read them on the RT target, then a cRIO-9012), except for these shared variables network-published with data type defined as Variant.  I'm not sure what is causing the problem.

  I take the table of clusters shown here...

  

  .. .and going through one "in Variant' VI and then subsequently in writing to the shared variable (data type: Variant).  Diagnosis of the failure of the VI in real-time to read the data, I found that variable writing shared on the host VI produced the following error:

  Error - 2147467259 appeared to Variable shared in the PC host TTS CTRL.vi

  Possible reasons:

  LabVIEW: Unspecified error (Hex 0x80004005).
  =========================
  System OR Configuration: Various operating default (Hex 0x80004005).

  This error or warning occurred when writing the following shared Variable:
  Shared \\My Computer\Network Variables\TC trust Array Group - network
  Shared \\128.144.90.143\Network Variables\TC trust Array Group - network

  .. where 128.144.90.143 is the IP address of the PC.

  Any thoughts?

  I saw this post, and when I found myself with no other option, I have redefined the variables in question to the string data type and replaced all the "to variant" and "given Variant of ' functions with functions 'Flatten channel' and"The string Unflatten"respectively.  Initially, it did not work - functions "Chain Unflatten" would produce error 74, until I realized that the "data includes array or string of size? (T)"input on each 'string Unflatten" function must be set to FALSE. Wiring a constant false for each instance of "Unflatten to the string" seems to have corrected the problem.

  I have still no idea why wouldn t Variant.  Shared variables Editor allows to define a variant data type, so I guess it's supposed to?

• LabVIEW oop variant in the private class data

  Hello

  I'm new to LabVIEW OOP.

  Is there a way to get a control of type variant in the 'grouping of private class data"for a class? If not, is there an alternative for handeling given variant? I use LV 2013.

  Thank you.

  Just, you use a control of type variant, and put in the big giant cluster.  It's the same for any other data type.  Is there a specific problem that you run into?

• calendar, given to conspire

  Hi all
  I'm working on my degree work and I need help with a few problems. I want to try to acquire data from my system using Labview instead of matlab /simulink. I need only a simple function to acquire and plot the data.

  I have my system connected to the NI USB 6009. After starting the program I want to gain the release of the system (it works) trace it (work), but sometimes unique graphic problem, I want to draw out system and NI USB-6009 (now I do it in 2 separate graph) no answer. I find, which can be done with the help of table, but it does not work for me... Data collected, written in excellent worsheet (date/time and output system). Here I want to write on the worksheet only 3 columns, 3 values: "time in seconds |" OR USB6009_output | sys_output ".
  Can anyone help? I know that these issues are simple, but I am a beginner and time is counted up really quick.

  out of the system is affected by the noise, I want to build a low-pass filter on everything in a loop (I create this filter in another project of VI). With connected filter the final structure of spreadsheet hold by: "time in seconds |" OR USB6009_output | sys_output | sys_ouput_filtered ".
  Sorry for my English and thanks for the replies.

  Best regards

  Paul.

  You were close to the solution, but using the wrong function.  By adding the waveforms will display one then the other.

  Overlay, first create an array and use the align the Timing of waveform.

  Hello

  I tried to change the .xlsx to .xls and it gives a note at the opening of the file "the file you are trying to open, abc.xls, is in a different format that it is specified by the file extension. Check that the file is not corrupted and precedes from a trusted source before you open the file. Do you want to open it now? »

  When you rename the file does not solve your problem.
  Anton Scheffer package generates a file in format xlsx Office 2010. When rename you it with the .xls extension, then Office 2010 will give you the warning that the file format does not match the extension.

  but the requirement has to generate excel 2003 file.

  The xml_spreadsheet package writes a format that was introduced with Office 2003, but you must use .xml as extension in other Office 2010 will give you the same caveat.
  To write the real xls version (binary), you can use Apache POI. You will need to import Java classes in your db and write a PL/SQL wrapper. Or you can use one of the options above, writing the output to a windows server and then use Excel to open and save in the required format.

  You must decide whether it is easier to write the binary xls format or to convince the customer to accept other formats that can be opened with Excel.

• DAQmx property in event node can % 27T be update

  I want to update the node property of DAQmx event to update dynamically the value, but only 1 of the 2 property node can be updated "DAQmx is task Done.vi", the whole could be triged normally.

  As shown in the photo below: report cyclic case can be triged and run, but the value of property not upgrade vi DAQmx. well frequency one normally.

  

  

  

  The answer is probably more strange than you expect.  It turns out that the two impulses of the synchronization frequency and duty cycle parameters are also privileged.  (I believe that the same kind of asymmetry applies when you set a pulse with high and low time).

  Frequency Gets the privilege in this sense the pulses of timing is changed only when a frequency value is written.  In order to change the operating factor, you need to get a property node DAQmx Channel, expose the properties of duty cycle and frequency and write to both of them.  You don't need to change the * value * you write in the property of frequency, but you * need to write for her.   Given that written node property follow these up and down, it is important to have the property of cyclical report above the frequency property.

• CSV to XLS

  Many people.

  I would like to use Labview to convert a csv file in a spreadsheet xls file.

  I was thinking about labview could open the worksheet, to seek the commas ',' and convert them into a ' / t.

  is there a search function that does this?

  A spreadsheet XLS file has a lot of different things in it except using tab vs comma for the delimiter. A XLS file is a Microsoft proprietary format that needs to be written from Excel. (Which can be done through LabVIEW) If you just want to convert a text file of values separated by commas in a tab delimited text file, it's easy, see extract attached

• Visual Studio Message Cluster LVUserEvent

  Hi, it is possible to use a queue to exchange messages between a .dll and LabVIEW? Yes. Cheque image.

  It is posilbe that the data contained in a variant of the cluster and are? You can convert a given variant in .dll and convert a Variant labview data for data?

  And I tried to implement a function with the following code, but I made a mistake when I run LabVIEW.

  #pragma pack (push) 1.
  typedef struct
  {
  LStrHandle newStringHandle;
  LvVariant * data;
  } MessageCluster;
  #pragma pack (POP)

  ...

  Message MessageCluster;

  ...

  PostLVUserEvent(*rwer, (void*) & Message);

  Thank you very much.

  No, the Variant C API is not documented and so there is no way to create, query, modify or otherwise use from C code, if you are not a developer of NOR. Use the documented data types.

• date/time string tabs

  Hello!

  I have a problem with the date/time string format VI. I would like to define the date and time with a tab to see the date and time in different columns so when I opened the data written in excellent... but I can´t! I ve tried with \t in the bar code backslash... (% d/%b\t%H:%M:%S%2u), also with concatenate strings with a constant of the tab in the middle... (as illustrated in attached piece) but the extent of my file the tab written as \09 (14/May\0911:00:20.25) s. The strange thing is that when I use \s (space code) it works fine... Why does only not with the tabs?

  Thank you very much for your answers!

  Hi Mia,.

  as I have LV8 + at the moment I can't dig deep - can someone else check this Express VI (stay away from them )

  You can use simple 'write in the text file' calls instead, just use 'picture to a worksheet string' on your data. That's what I'd do... (Express screws are nice start using LabView or quickly write code running - but they hide all the interesting stuff and won't provide any flexibility for special needs!) And they always need conversion into "dynamic data", which also hides the user's information. Did I mention I don't like screws Express?)

• Query by example (QBE) for af:table - how to replace the filter "start with the behavior".

  ADF 11 g

  On a table with active QBE, a user can type an entry in the QBE and the search always seems to do a search 'start with '. For example:

  If I get a 'P' in the filter, then it will match '% P '.

  I would like to change this option to find "exact", if you want to.

  Is there a way to bypass this behavior?

• How to use loadFont()?

  When we want to use a font of the application, but it is not installed on the local system, then how should we do? The use of Font.loadFont () is read and install a font since the police resource file (file formats that support the JavaFX are what?). If we use the Font.loadFont () every time that the application starts? That is to say to install the font every time that the application starts? I think it will increase overhead costs. Why can't we install a font only once and use it forever?

  If you have installed the font locally on the system, then you don't need to call loadFont. JavaFX leverages the native operating system to tell which fonts are available, and when you create a new policy, it will ask the native OS to open the font file and give it the glyphs to use, measures, etc.. However if you have a custom font that does not have the native operating system, then you must speak to JavaFX. This is what the method loadFont. JavaFX will not install the fonts on the native operating system for you with this call, it it loads just for the duration of the application is running. It's also the way that web fonts work in HTML.

  The font (opentype, ttf) file can be in your jar, on the net, or on the file system local or anywhere you can generate an InputStream of. Heck, you might have the bytes in a class file :-).

  Jasper has written an excellent blog on loading the fonts via the web on FXExperience: http://fxexperience.com/2012/12/use-webgoogle-fonts-in-javafx/

• Can I write a macro that will extract pages

  I'm good enough to use Microsoft in VBA for macros written in Excel.  I wonder if Acrobat has something similar to manipulate pdf files.  My company has a large number of PDF files we want to split into smaller documents.  I would like to be able to write a script that would look for some passages, then according to the page where he found the text, he would extract a range of pages in a new document.  Think of it as holding a book and the breaking of macros it upward into chapters each chapter would be it's own PDF file.  Even better would be the macro for it to all files in a folder.  Is something like this in Acrobat?

  It is possible with JavaScript. JavaScript can be used in a sequence of batch (aka Action), to deal with a collection of documents.

  Here are the basic methods you would use:

• Given MS Office Toolkit report column heading of development shaped as a line in Excel

  ... Sorry for the double post... I'm having issues this morning.

  I know I'll feel stupid when I have the answer for this one.  But I do not get any where my own now.

  I use MS Office report tool to create an Excel report from a table in a LabVIEW application.

  I spent some time to find how create ranges named in the Excel template, I created.  This seems to work, because I can see the entries to the icon on the LabVIEW diagram.

  The problem I have is with the headers of the columns in the Table.

  I created a named range that is a whole line of my Excel template.  When I use the node property to send the header of column values to the model, the data appear as a column in the spreadsheet.  So far, I could not find a way to get this data as a line instead of a column.

  Is there a way?

  

  Looks like I found my own answer.

  Seems like all I have to do was to convert my header data in a 2D array.

  

  Don't know why we were so difficult to understand.  But it's working now.
