• 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!

• 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.

• 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.

• Try to write data to the file, but error 200279

  I have problems when writing data to a file. 10 seconds in the recording process, I get the error 200279. I did some research on the subject, but I am unable to corect my code. I think I want to increase the size of the buffer, but he prefers, I suppose, to read the data more frequently. The way that I save my file is, before starting the VI, I attribute a location and name of the file (e.g. data.csv). The date and time is added at the end of the actual when file the I start to record the data (e.g. data_07-26 - 13_122615.csv). If the file does not exist, it creates a new file, and then adds the data of this file after each iteration of the loop. The reason why I did this way was so I don't have to worry about running out of memory, but apparently my code is wrong.

  

  

  I will include a copy of the faulty section of my code. Any help would be greatly appreciated.

  Thank you.

  Your problem is that the writing on the disk is slow.  It is pretty slow so it causes your DAQ buffer overflow and cause error and loss of data.  What you need to do is to implement a producer/consumer.  This will put the data acquisition and recording on the disc in separate loops.  This will allow data acquisition work at speed, that he needs to deal with incoming samples and writing on disk can run at all what pace, he can.  You send data from data acquisition to the loop of logging using a queue.

  You can also think about changing how you write to the file.  VI is constantly open and close the file, which is a very slow process if you do it inside a loop.

• How to move data from flat file to the repository of execution

  Hi all
  
  We have 2 instances
  
  1. development - we are able to move the data from flat file to target the DB using scenario1.
  
  The files are in 04 who's ODI installation box
  
  
  2. enforcement Repo
  
  to scenario1 execution repo installed in ODI 07 which is ODI installation box
  but not able to move the data from flat file to target DB.
  
  We get an error - file not found.
  
  File is located in the box 04.
  
  My question is that what is the best process to make scenario1 course migrated to work.
  
  Appreciate your help.

  I wanted to say that in view of the dev and prod in the Prod repository agent is not a good idea.

  Ideally, in repo Prod, you must have prod 07 agent.

  In Dev Repo, you shouldn't have dev 04 agent

• How can I save a single file every hour?

  I have a folder on my desktop I want to back up every hour approximately. so that if something happens to him, I could just copy and paste the version, so I just want to make a copy of the file. For example, at the moment I'm just copy and paste the folder into another folder every time I check it, about once a day and it is very annoying and I would like to automate this process. The record is a world for a game and I want to copy the file every hour, so that I can have a selection that I can restore from. Sorry if im doing not a lot of sense. But if someone understands what says im and could help id be very grateful!

  Thanks in advance

  Hi Josh,.

  It is not possible on this specific issue.

  As an alternative, you can download and install the SkyDrive to Windows desktop application.

  You can add this file on SkyDrive and whenever you make changes, it will automatically change into the SkyDrive folder.

  You must be connected to the network, in order to get the changes take effect in the SkyDrive folder.

  For more information, see the articles:

• How to write to an existing file, but replace the data just to the last row

  In my data acquisition system, the columns represent the channels and each represent line analysis of the data for all channels. It is easy to get the file write by add or replace a file exist. But sometimes I want to just overwriting new data in the last line in a file exist. for example: I have DAQ with 10 channels and scan all channels for three times in each race. So my data file will be 10 columns and 3 rows of each run if I put the file "append". next time I want to record the data by "crash" (so a single row of 3 scans) in the same file but just crash to 11th place (so I'm going to keep all the data I had previously). How to do this?

  Hi GPIB Analyzer.

  Why do you need to read the entire file?

  You can:

  -get the size of file with 'Get file size' or 'file info '.

  -set the position of reading with "Set file position.

  You should subtract the file size 1024, define what the position of the file read 1024 bytes. Now analyze this 1 KB of data, find the last line, set the file again, write to the file. No need to read the entire file.

  And as previously stated:

  How Labview should know the last line in the file without looking for him? You can do this research better than a simple brute force attack
