• How to write a double waveform in an Excel file without blank lines of cells

  Hello

  I am writing two waveforms in an Excel file, I'm almost there, but the stumper is that after each data line, a blank line appears in the XL file.

  Probably something simple I forgot because I am fairly new to this.

  Thanks in advance,

• Control of data rows Excel (write on a file of measure)

  Hi all

  Objective:

  Get a bit of a live waveform of two pressure sensors, as well as calculate the differential pressure. The LabVIEW VI is intended for students for an exercise in module, in which data are exported to an excel file for the students to perform other calculations. Excel file must contain data from the beginning to the end of a race.

  Problem:

  Pressure sensors work well, waveform table works well, but when you stop the collection of data, the amount of lines in the file Excel output will reflect the number of samples per channel of the DAQmx Read Block (10 = 10 rows of data, 100 = 100 lines, etc.).

  I would appreciate some advice on how to conduct the data collection in the part worksheet from start to finish, without this affecting the aesthetic experience of the student (by that I mean the number of channels of the > 10 sample will cause some lag in the waveform, jerky). I tried to resolve this issue with something in the sense of Tank1Solution.png without success. I've included a photo of the original block (Tank2Block.png) and so I worked the file VI.  Once more, any help would be much appreciated, I'm not well versed in LabVIEW and I do not know how to address this problem effectively.

  Some guys are always doing things the hard way

  

  Of course, you need a son to ai0 - ai2 and ai1 - ai9.  This linear scale DAQmx is of course very convenient! and hey, the TDMS files import beautifully into Excel! the addon is there then why not just open a session data?  TDMS is much more portable than xlsx.

  A few additional remarks. (a) you can't stop this vi before you press Go-who needs a fix. (b) Create scale is likely to return an error as it is the name being illegal. I named it that to show the source of the scale and offset values.

• Remote access? 'other' user appears in the Excel file

  My husband uses Excel 2008 for Mac on his mini. Today, it has created a new Excel file, and when he went to save him, he did not allow him to do so. After I told him to try to "Get Info", he saw that there was another user listed as having access to 'wheel' (FIRST HMMMM?). None of us use this name. The permissions are set to read and write.

  I could, even if I don't have to open the lock, allowing to delete this user and change the permissions of the "Everybody". Always without having to open the lock.

  I open the lock using his password, made another change, saved and closed the file.

  I went in its security and confidentiality and found that the Firewall was turned off. I turned who, without having to open the lock. (DON'T know WHY I didn't have to open the lock.-SECOND HMMMM?)

  So, I changed his password, all closed and restarted the computer.

  No more 'wheel' on what it is, yet. The permissions are correct so far.

  HOW to know if someone would have managed to remotely access her computer? This doesn't seem to be that someone got access to distance?

  Person not? No ideas?

• How to import Excel file to GUI of LabWindow

  Does anyone know how to import the Excel file to LabWindow CVI GUI. Thank you

  It is not clear to me that you want to embed an Excel described in a panel of CVI or import data from the worksheet. CVI is delivered with an instrument ActiveX that you can use for reading Excel interface / write data from files. Otherwise, CVI can host Excel documents and interact with them. All these activities are conducted via a special instrument of ActiveX (Excel2000.fp).

  Interaction with Excel was often treated in the forums you can perform a query to extract useful information. There are also several examples that you can download and study to understand how to use these instruments: some of them are listed on this page.

• Adding a table Excel file using ActiveX

  Hello

  I want to add a figure that has been produced using data from data acquisition to a specific cell in my existing excel file (reversing a graphical indicator in jpg/bmp,... and put it in the excel file). But I can't find the specific method to do so. I have changed one of the examples so I can add a few numbers to a specific cell in excellent file (VI attached). Someone knows how to do this?

  Also, in my test, I'll do this for 15-20 numbers (put 20 numbers in different places in the existing Excel file). I do this one by one? (opening of the application 20 times) or there is a way to just do all at the same time.

  Thank you.

  Now, it looks a lot better.

  I also added the part in which the image is from a waveform graph. For this you must use the Invoke node Export Image waveform graph. I've exported as bmp, save it in a file and then added in Excel. It is a solution. You can try different image format in order to find the one that works best for you. BMP is big enough.

  Another solution would be to use the graphical waveform / invoke node / export the Clipbord Image and spreadsheet use invoke node function / paste. In this way, that you don't have to write the image to the file. Although I find it more difficult to control the position where the image is pasted. In any case, you can give it a try and play with her a little.

  You can build your complete code Export To Excel using this example. Just add a loop (or code) between the opening of the workbook and close it.

  PS: I hope that the waveform graph node is the same also in LV2010. I can verify that Monday.

• Problems with writing in an Excel file

  Hello

  I'm working on a program in Labview that should read the data, do it on a table and transfer in real time to an Excel file. I have already done that there is however a few problems I have week solve so I'm here to share with you and help fix them if possible:

  (1) the excel file that I use to write has some defined functions on it, used to make calculations with transferred values and whenever I run

  my program every thing on the file is overwritten even functions.

  (2) I have specify the rows/columns where I need to write (ex: begin with row 4 column C in line 20 C column and jump colum B and line 14 and 15)

  (3) the VI should be saved automatically, I did everytnig I found on the forum OR but still does not.

  I guess that's not easy to do, but I really need help so I can continue my work.

  Thank you

• Is 'Spreadsheet.vi wire Delimited' identical 'write to worksheet File.vi?

  I can't find the "write to the File.vi spreadsheet" in 2015 Labview. I used to have 2012, but now I can not find it! I see others with a similar icon so I thought 'Spreadsheet.vi delimited wire' is the same, but when I read the help, it seems not the same!

  They are essentially the same thing. NEITHER changed the name because so many people thought you could read/write from/to excel. Adding the delimited Word makes it a little more specific.

  What you see is the difference?

  Write delimited spreadsheet

  Write to the spreadsheet file

  They must create the file even if the same inputs are used. Have you tried?

  The new Vi includes the clusters of the error, because the old version of spreadsheet used error automatic handkling (yuck).

• In palette I can find 'Write to worksheet File.vi' in 2015 of Labview?

  I get the signal from a sensor in DAQ hardware. After this treatment, I have three columns. Signal time - average - standard deviation

  I have trouble writing in an excel file. I used "Write to measure file.vi" but I don't know how to add columns inside and there is no place for labelling (give a title for the column). Also when I open my excel file, the time is as #.

  When I opened my old files with labview 2015 I see a big red X inside the icon of "write as file.vi. I remember, in 2012, it wasn't like this. Thank you for your help.

  No need to create a new topic for essentially the same issue. Use the write delimited spreadsheet VI for the same functionality.

• Write to the file in Question

  I do modeling experimental with a VI that many members of this Council greatly helped me go.  Part of this modelling is the creation of a periodic function.  I accomplished this by using 30 value entries 'Y' and a frequency to create sort of a 'function of unit', or basically, a period with a value of function, with a maximum amplitude of 1, while it is conveniently set on the scale.

  What I find is that it'd save these 'functions of the device' as well as their corresponding amplitude and frequency of file, that I cannot laod later in the program.  So, I need to write data to a file, (30 pairs of doubles, with 2 independent double rooms) and then have the opportunity to browse through all my saved both functions load the desired one.

  I used the express vi 'Write in a file as' before, but that seems to be a clumsy way to do it.  I then played with the various «write to...» "vi is available.

  For a relatively small set like that, is it interesting to a file rather than another type?  Of course, much data could go directly into an excel file, even if it should be reformatted to strings to store in the text.  I have little or no experience with bianary files.

  All file types are easier to load then go?

  And is it possible to have the (previously saved) functions available and selectable ring of menu, or will it prompt the user?

  That said, I'm looking for some general advice on the region.  I've read all the help files associated with and read some threads on the specific issue.  But being new, I'd like to hear how you professionals would approach this function.

  My current code is attached.

  
  

• Several tables to excel file

  Hello

  I get this error when writing two different tables for the same excel file. I think the problem is that the excel file must be closed to be written the new. But I am unable to use the narrow leader because he is not a refnum. Should I use the notifier? If Yes please tell me how to thank you.

  In your VI, you have two instances of "Easy Excel Table.vi" that will run in parallel. This is likely to cause a conflict, because as we open and written on the worksheet, the second will also try to open the same spreadsheet and write at the same time. You must apply a sequential operation in order to ensure that the second simple Excel table can operate only when the first has been completed. The easiest way to do this in your VI is over the error of the first VI on the second VI error, so the second can run only after the first ended.

  Secondly, the second VI also has a function of "New Report.vi", pointing to the same file, so there is a good possibility that this will overwrite your changes. You say there is no reference to the excel file, but in fact there. The right upper bound of the first easy table Excel vi is the report's reference. The wire that directly in the Terminal to the second function Excel easy table report and get rid of the new Report.vi.

• Excel file is not recognized by Matlab

  Hello

  I'm saving my data (with headers) using the function 'Write to a spreadsheet file' in file .xls. Windows will recognize such as Excel and it opened ok. But when I'm reading in Matlab by function "xlsread", I get an error "not in the Microsoft Excel Format".

  Where I'm wrong?
  (I have attached my code: it's the creative header Subvi; digital data is added in additional Subvi by using the function 'Write to a spreadsheet file' even)

  Hello Dvorkind,

  I thank very you much for your message on our forum. There is a difference between a file delimited by tabs and an excel file, and I think that it is the source of the problem, that we are facing here. Please consult the following KB .

  Here, they speak the tool report generation (you can try assessment to see if this solution will solve the problem). Alternatively, you can try to Excel by using the possibilities of activeX in Labview.

  I hope this will help you in addition,

  Best regards
