• write data 2D table spreadsheet with good alignment

  With 'write in the spreadsheet file' function to write the 2D table, I still have the problem that headers may not align well wiith data. See attached snapshot please (there are 7 column headers).

  The default field delimiter is a tab. The data in the second and third columns values seem to have more characters than the default spacing of a tab. This translates into the tabs between these columns that occur more to the right than in the header. I think that if you read the file as text and display with ' \' Codes display mode on an indicator of the chain, you will find the same number of tabs (delimiters) in the header line like the rows of data.  The data have 12 or 13 characters such as formatting (or less where the zeros on the right are deleted).

  Format the data as of the fixed field widths. This is impossible with writing to the File.vi worksheet. You do not have to use the string to perform conversions and put in shape and then use the writing of text File.vi.

  Or change the spacing of tab in the program that you use to display the results.  If the tabs were approximately 15-18 spaces, reveal you do not see the problem.

• Save and write data from table to table - easy

  Hello

  I got this system delivered to me. I'm new to LabView and just save the data from the table "average voltage" (inside the while loop) to do some additional testing of our product.

  I will like to do similar to this.

  (1) save in excel file.

  (2) save only when a button button and save it then 5 ilteration.

  (3) save and manipulate the data, so it is displayed in 6 columns (each LED 1) instead of 1 long colum.

  I tried different things with structure business T/F, which resolved the buttom-request. But I am in doubt I should use, writing to the file of the measurement or write to us to the worksheet (by using labview 15.0)-delimited according to my offer the best possible?

  He also seems to be too much to handle when I try to write in txt file, because it pops up with and error that I do not know how to fix, but it says this:

  Error-200279

  Possible reasons:

  The application is not able to cope with the acquisition of equipment.

  Increase in the size of buffer, most frequently the reading of data or by specifying a fixed number of samples to read instead of reading all available samples would correct the problem.

  I agree with Taki, but want to make some additional remarks:

  • LabVIEW is a data flow language.  Think of the "flow" of your data.  You talk about "save only when a key is pressed" and a finite set of data.  You are collecting before the press the button and everything just do not save?
  • Data are collected at some rate, and likely, you don't want to "Miss" data points.  This means that you shouldn't do anything in the loop of the Collection that takes a long time.  If your recovery rate is low and your treatment is fast, you can have everything in a single loop.  Otherwise, to use the technical stream (producer/consumer is a good) to process the data in a single loop in parallel with the collection in a loop independent (and asynchronously).
  • How do you write your data?  You want to write "on the fly", as it is, or can you wait, collect everything, any format and then write it "all at once"?
  • What do you mean by 'save the file in Excel?  Do you mean a 'native' Excel file, one with the extension .xls or .xlsx?  Do you mean a Comma-Separated Variable (.csv) file this reading peut of Excel (and, indeed, usually registers itself to read, change the icon of the .csv files to "look like" it is really an Excel file)?  If the first case, I recommend using the report generation tool.  But for the latter, you can also use write delimited spreadsheet, which can be easier to use.

• Write data to a 2D array in different directions

  Hello community,

  How can I write data to a table in different directions?

  Here's my vi, but I don't know how to do it in LabVIEW.

  Thank you for your answer

  Jeff· Þ· Bohrer says:

  I'm off today and I have no available LabVIEW.  I'll look in @ Thursday.  I bet others will fight for a solution.

  Well, well, well!  Once the ball 8 missed by a mile!  Nobody went to the city and got jiggy on the problem!  It really was a fun little vi to write.  I'll start with a tease: Code captures (Backsaved to 9.0 because this not depend on features that have not been around for a very long time) to follow in a spoiler.  For those playing the game for fun and games, duplicating the code without looking at the backdoor.

• How to transfer data from the data in table 2D only once file?

  Attached file will write same data in table 4 times 2D file. Output must be in a table 2D.

  Someone will provide a solution or a reason to explain why the data are been ouputted 3 more times? Thank you

  I already told you a better and more effective method. The function of reading worksheet is on the exact same range as your text file and does everything for you. If you insist for some reason strange kernel to reinvent the wheel and write your own code, take the correct path. The use of 4 separate spreadsheet String to Array is the cause of your problem and I already said too much. Don't you think that get you 4 times the data is in correlation with the fact you are using 4 times the functions necessary at all? It is simply not true. Look at the diagram-writing block on a spreadsheet file.

• error when pass array 1 d by data in table pointer via Labview-built c++ dll

  I'm trying to generate a Labview VI to a DLL and let it be invoked by vc ++, by which a 1 d array is passed. However, I can't generate the DLL when you use the data pointer to the table, which gives the error like below:

  [ERROR]
  Code :-2147221480
  Strengthening of the DLL.
  Error when compiling the DLL as a function name or a parameter is illegal. Check function and parameter names are legal C identifiers and are not inconsistent with the LabVIEW headers.
  Additional information: 9 project link errors
  Type Library generate error. MIDL.exe failed during the compilation of the odl file used to create the type library.
  Note: The error indicates that the odl file has unknown types. This error is possible when
  works with non-standard types is exported using the method qualifier exporting files in
  release the configuration that have not been recompiled during the build process.

  The Prototype of VI define is as below

  

  But, if I use the pointer to manage through the table, the generation is successful, error-free. I write something to call the DLL built labview, which basically reads 1000 double the data of an instrument.

  #include "TestDQMaxDLL.h"
  #include 
  
  using namespace std;
  
  int main(int argc, char** argv) {
      cout << "Start testing DQMax DLL" << endl;
  
      int leng{ 1000 };
      DoubleArray rawDPData = AllocateDoubleArray(leng);
      test_dqmax_dll(&rawDPData);
      cout << "Successfully invoked the DLL!" << endl;
      cout << "DoubleArray.len: " << (*rawDPData)->dimSize << endl;
      for (int i = 0; i < leng; i++)
      {
          cout << (*(rawDPData + i))->elt[0] << "\t";
          if (0 == i % 10)
          cout << endl;
      }
  
      system("pause");
  
      DeAllocateDoubleArray(&rawDPData);
  }
  

  But the printed results are not correct.

  My questions are:

  1. why cannot generate DLLS with the data of table pointer. In this case, the argument of the function is as simple as a double array.

  2. for table handle pointer, when the resutls are incorrect and how to get the good ones.

  Any comments would be appreciated.

  BTW: I use Labview 2012 with Visual c ++ 2013 on Windows7 64 bit.

  I never needed to pass a table of LabVIEW handle external code. Search this forum for posts of RolfK, it is most likely to have posted such an example. I recommend that you keep things simple and remodelling your table a table 1 d 2D before moving on to external code and manage as a 1 d table (it's just a little extra math).

  Sorry I don't have a solution on why you can't build with a 1 d as a pointer of table table. If you post your project I'm happy to try to build (I'm on LabVIEW 2012, however), but as you said, it will rely on another machine, it seems more likely to be a problem with something on the specific computer where there is a problem.

• How to write data in an Excel spreadsheet protected (with unlocked cells)?

  Hello!

  I have LabVIEW 8.2 and I often use the report Generation Toolkit for Microsoft Office' to save data in Excel spreadsheets. So far, I only used the leaves unprotected.

  But right now, I have an Excel worksheet protected by some cells unlocked. If I open the file using Excel I can fill these unlocked cells without any problem. However, I am not being able to fill these cells unlocked using LabVIEW and the Toolbox. I have a few questions:

  (1) is it possible to use LabVIEW to write data in a protected Excel worksheet, even though she has unlocked the cells?

  (2) if it is possible, how can I do that?

  OBS: I noticed that if I unprotect the sheet, I can write data to the file. But I don't want to be protected and the protection of the sheet, since users will not have the password.

  I hope that I was clear. I really appreciate any help you can provide.

  Thanks for the replies.

  Use ActiveX I could write the cells individually. By doing this, I could write in the unprotected cells without any problem. hour

  Probably, the Toolbox has been activated somehow the overall protection of the spreadsheet and Excel was not allowing writing.

  I had never used before ActiveX, so I had to learn it from scratch. I was looking for some tutorials on the internet but I have not found much information easy. What struck me the most help is an example that comes with LabVIEW named "Excel - write Table.vi. After some tests, I was able to open my data protected from the worksheet and fill in the unlocked cells.

  Thank you guys!

• How constantly write data in a txt file

  Hello
  first of all, sorry for the bad English, but I have a problem to write data continuously to the txt file... I have a chart 2D with values based 2 sliders (sliders values) and some functions I want to interpolate the value by using the bilinear method... and after that the value of the sliders, interpolated value and the value of the closest points, I want to write to a file txt... for every 2-3 seconds perhaps, it would be ideal to be formatted as ::
  x y f f1 f2 f3 f4
  ..   ..  .. . .. .   ..   ...  . ..
  ... ...  ..    ...   ...   ...   ...

  but... first of all I have a problem with writing data, because every time he deletes old data and simply write a new and it is not horizontal... I am very very new to this (it's obvious) and any help will be very grateful 
  Thank you

  

  Diane beat me to it, I made a few changes to your code, so I'll post it anyway.

  

  As proposed, please go through the tutorials.

  I added an entry to the worksheet at the end node just to show it can be done at the end so. Table of building on a while loop is not very efficient memory, but it's just to show you what can be done. If you plan to go this route, initialize an array and use the subset to the table replace.

  All the best.

• How can I write in a table cell (row, column appear) in a databae?

  How can I write in a table cell (row, column appear) in a database using LabVIEW Database Toolkit? I use Ms Access. Suppose I have three columns in a table, I write 1 row of the 1st column, then 1st rank of the 3rd column. The problem I have is after writing the 1st column of 1st row, the reference goes to the second row, and if I write in the 3rd column, he goes to the 2nd row 3rd column. Any suggestion?

  When you perform a SQL INSERT command, you create a new line. If you want to change an existing line, you must use the UPDATE command (i.e. UPDATE tablename SET column = value WHERE some_column = some_value). The some_column could be the unique ID of each line, date and time, etc.

  I don't know what is the function to use in the Toolbox to execute a SQL command, since I do not use the Toolbox. Also, I don't understand why you don't do a single INSERT. It would be much faster.

• Charger data warehouse does not write data

  Hello
  
  I need to know which products are the most popular, I know the tables to store this information
  and ARF_QUERY ARF_QUESTION. I already have the charger running data warehouse module, if anyone knows
  Why data warehouse loader does not write data in the database, I thank you.
  
  I thank.

  The planner should treat the logs on a daily basis (by default the calendar begins charge to 22:00 and ends at 6:00). If you want to call the treatment yourself simply call the method loadAllAvailable of the SearchQueryLoader component. You can do this via the dyn/admin.

• Edit/view (data or Table column) value - cannot change the data, but it can be updated

  Hello
  
  According to the help of Oracle SQL Developer Center, the dialog ' Change/see value (data or Table column)' should "change the value of data" if we "are allowed to change the data." We strive to use this dialog box to modify/update data without having to write an Update statement, but is not to leave us. Us are not allowed to update the data, we can update via update statements.

• Qosmio X 500 does not write data to any CD

  I have a Qosmio X 500 with windows 7 (64-bit) home about this, my CD-Rom used to work fine, now it reads and serious DVD and blue-ray, but it will not read or burn CDs.

  I have no more or less than the registry filter.
  How can I solve this problem?

  Hello

  Have you tried different CDs from different manufacturers?
  Try the CD R TDK.
  I use this kind of CD and never had any problems, but had problems to write data to the other CD.

  In addition, you can try to clean the laser lens you can use a piece of hydrophilic cotton and a very small little alcohol which should be good enough.

  By the way: fire what app do you use? In my opinion Nero is great software, one of the best software in this segment.

• Satellite P500/01R reads the data, but cannot write data on CD files

  I recently bought a laptop Satellite P500/01R. I am able to read a data CD, but can't write data on CD files. The CD is read/write.

  Any ideas?

  Hello

  Have you tried different burning software?
  I m using Nero and in my opinion one of the apps better combustion.
  Here, I can choose between CD, DVD, DL or Blueray (only possible if the CD/DVD drive also supports this).

  Have you also checked diffΘrents CDs from different manufacturers?
  You should do this since not all disks are 100% compatible.
  I had several problems with different CD or DVD in most of the cases it was a compatibility issue, I tried TDK and this kind of drive is compatible with my CD/DVD drive
  I m using the standard of R.

• Write data to text file generates the error

  Hi all

  I need to write data to a file using TestStand and I configired the entrance and outside like below, but I get the error message like ' an error occurred 'Write' calling in 'ITextStream' of 'Microsoft Scripting Runtime' [error Code:-2146828234].

  I followed the same procedure for reading text that works very well for me.

  Hope others might have faced the problem / or I do something wrong.

  Do what is necessary.

  

  Found problem while opening a file I used IO Mode ForReading instead of ForWriting.

  Unnecessarily the thread created, but then hope this can help someone later when they deal with a particular issue.
