• 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!

• DASYLab how to write data to a file every 15 minutes

  Hi all

  I use dasylab and datashuttle/3000 to record data. What I want to do is to write data to a file every 15 minutes. I use the milti-file, which can write data to the file diffenret, but how do I control the timing, as the journal data every 15 minutes automatically.

  The other problem is that I use FFT analysis of the frequency spectrum. How can I determine the value of frequency where the peaks that happens.

  Thank you

  Write less data in the file that you have collected requires the reduction of certain data.

  There are three techniques to consider.

  With an average or an average of block - both reduce the data by using a function of averaging, defined in the module. To accomplish the reduction of data, choose block or RHM mode in the dialog box properties, and then enter the number of samples/data values that you want to reach on average.

  Average - when you reduce the data, you also should reblock data using the block length of the change in the output parameter. For example if you enjoy at 100 samples/second with a block size of 64, the average module configured on average, more than 10 samples will take 10 times longer to fill a block. The initial block represent 0.64 seconds, the output block represent 6.4 seconds at a sampling rate of 10 samples/second. If you change the size of output in one block, the program remains sensitive.

  Average block - average values in a block against each subsequent block, where the average is based position. The first samples are averaged, all second samples are average... etc. The output is a block of data, where each position has been averaged over the previous blocks. This is how you will be an average data FFT or histogram, for example, because the x-axis has been transformed in Hz or bins.

  Second technique - separate module. This allows to reduce the data and the effective sampling rate jumping blocks or samples. For example, to reduce the data in 1000 samples / second to 100 samples per second, configure the module to keep a sample, jumping 9, keep one, jumping 9, etc. If you configure to skip blocks, you will not reduce the sampling frequency, but will reduce the overall amount of data in a single block 9, for example. It is appropriate for the FFT data or histogram, for example, to have the context of the correct data.

  Finally, you can use a relay and a synchronization module module to control. For example, to reduce a sample data every 15 seconds, configure a generator module of TTL pulses for a cycle of 15 seconds of time. Connect it to a Combi trigger module and configure it to trigger on rising and stop the outbreak directly, with a trigger value after 1. The trigger output connects to the X of the relay command input.

  In addition to these techniques, you can change the third technique to allow a variable duration using a combination of other modules.

  Many of these techniques are covered in the help-tutorial-Quickstart, as the data reduction is one of the most frequently asked questions.

  In regards to the FFT... use the module of statistical values in order to obtain the Maximum and the Max Position. The Position of Max will be the value of the frequency associated with the Maximum value. The output of the statistics module is a single sample per block. Look at the different FFT sample installed in the worksheet calculation/examples folder.

• 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.

• 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).

  

  WT

  LV2013sp1

  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.

• How to write data from the acquisition of data in NetCDF format?

  I connect to a set of data from the sensor through the DAQ assistant and want to write all data in NetCDF format. I have the required plugins installed, but still can not find how to do this.

  Or the labview can only read the netcdf files, but cannot write it! Please let me know if there is any other way out. I have looked everywhere but could not find something useful!

  Thank you

  Hey,.

  Sorry, the sheet in effect only allows to read NetCDF files, not writing to the NetCDF format.

  Kind regards

• How to write data OR DAQ of buffer to stdout in ANSI C?

  I'm totally new to NIDAQ. I searched this forum and not found a solution to my problem - everyone works with LabView, not in ANSI C. I use NIDAQmx with ANSI C on Windows XP. It is easy to capture data using the ANSI C API provided with the NIDAQ. Data is automatically stored in a buffer provided by the API. Question: How can we get the information from the buffer? For example, if we wanted to taste 1000 samples (let's say, an analog input channel as well as a digital input channel). At the end of the data collection, I want to print the data that have been recorded, for example to the stdout device. Just a small pointer in the right direction would be extremely helpful! None of the files example C (supplied with the NIDAQ) don't file output data that have been recorded. You should know the format in which the data is stored in the buffer, and the buffer structure to access the items in the buffer.

  
  

• How to save data in mode 4 bits instead of U8

  Hello

  I use LabVIEW to acquire and record data through the meter timer PCI6602.

  My signals is really low while data can be expressed in 4-bit (0-15).

  I used the conversion in U8 and write using "write binary files.

  If it uses 1 byte for each data point, but I would like to reduce it to 4 bits (half bytes) for each data point.

  Can someone help me with this?

  I enclose my program for reference

  Hi TonP,

  at least on my computer with LV7 multiplying by 16 is faster than rotation of 4 bits

• How to change date if time existed with date?

  Dear friends,

  I have a table and the date is at the same time with time in the entry_date field.

  data are like below in the field entry_date

  01/02/2014 08:00:03

  08:00:09 01/02/2014

  my SQL is

  update problems

  set ENTRY_Date = 1 January 2014"

  WHERE ENTRY_DATE = January 2, 2014;

  but the date is not changed. Please help how do I do this? I will be grateful

  Kind regards

  you could do:

  UPDATE problems

  SET entry_date = date ' 2014-01-01'

  WHERE TRUNC (entry_date) = date '' 2014-01-02;

  but he doesn't know a relay on entry_date index

  the opposite would be

  UPDATE problems

  SET entry_date = date ' 2014-01-01'

  "WHERE the entry_date > = date '" 2014-01-02

  AND entry_date< date="">

  both ways will define your entry_date at 00:00:00 January 1, 2014 - so any component "hour" that was in the entry_date is set at midnight.
