How can I creat or open an excel file in labview?

I am using Labview 7.1 and report generation toolkit. I got the example code from this address :"Creating a report in Microsft excel using the labview report generation toolkit"
But seems this example only can creat report when the excel file exist, otherwise it will get error code 7.
How can I creat a new file if it doesn't exist and open the file if it exist? Can I creat a report without openning excel because I need to creat more than one report and check it after the test.
Thanks

Simply use the "Open/Create/Replace File.vi, and wire a constant "Create / Replace".
Wire a path/filename and make sure the name ends with the extention .xls
If you have multiple lines (likely), place aech line in an array and use the "Array to Spreadsheet String.vi" before sending it to "Write to file.vi". Don't forget to close the file.
Hope this helps..

How can I read fast 50 MB Excel file in LabVIEW

Hi,
I have created a datalog file containing string i/p and having extension ".exl". File size is around 50 MB. When I read this file using LabVIEW, it takes 1/2 hour to display data in Array. How can I minimize this read time in LabVIEW. Or is there any options available to create large datalog files with string i/p and read it fast?
Examples are well appriciated.
Thanks.

What kind of file is it? If you are writing datalog files, there is no reason for giving them excel (.xls) extensions. Excel cannot read datalog files. The other way around, native excel files cannot directly be read by Labview.
In general terms this is what you may look into:
-use a compact file format like (real)datalog, fully binary or at worst plain ascii text file.
-you do not have to read the whole file into memory at once, depending on your application.
-look at your (RAM) memory space: it sounds like you are running very low on memory and the OS needs to pagefile most of it. Try closing all unnecesary programs and/or buy more memory. Also look for memory hogging inside your code: releasing data that is no longer needed will free memory used by labview. "Uninitialized" arrays for example may seriously slow down a computer.

HI Dave,
I'm surprised you get no message when you attempt opening the Excel document in Numbers.
I'm assuming Numbers 3.1, since you are running Mavericks.
Does the Numbers file that opens show any content?
Does it contain a table?
How large?
Does it contain more than one tab (indicating more than one sheet)?
Do those other tabs contain a table?
Have you checked those tables for data content?
There have been cases in the past of imported documents opening with white text on a white background, giving the appearance of containing nothing. Check for this by selecting a block of cells, then applying a Fill colour or a Text colour using the Format button (paintbrush).
I'd also suggest attempting to open the Excel files using LibreOffice, which can be downloaded from the linked website.

Barry

How can I convert my Open Source document files into Word document files? I cannot download Pages since my Macbook Air does not have the most recent software.

How can I convert my Open Source document files into Word document files? I cannot download Pages since my Macbook Air does not have the most recent software. I downloaded open office to my mac to try and save money. It worked well for a while. Now I get this pop-up message that asks me to "Reopen" and when I select the option, nothing happens. I cannot save my documents anymore and I cannot convert them to word. Help!

You have 17 options to save as in Open Office, one of which is .doc files, yes it needs to be saved manually.
You may be able to default to DOC, but have not tried same.
Since Open Office is 99% same as Word, I use it, or Word, either one. Open Office is a bit less buggy than Word 11'

How to open an excel file from labview?

I tried to use "open file" vi from File I/O -- Advanced file functions to open an excel file in LabVIEW. Why the excel file wouldn't open after I run the program?

In addition to ActiveX, you can also manipulate Excel data files using the Windows ADO interface - a technique that is more robust, faster and IMHO easier. Do a search on the forum as there have been several threads within the last week or so discussing this very thing.

Why does TDM Importer start up when I open an Excel file in LabVIEW, and how can I stop it?

I have a new application using LabVIEW 2012 SP1. I open an Excel file using the Report Generation toolkit and when I do so, a small TDM Importer window pops up on top of the Excel file.
How can I prevent this?

Hi Steve,
The TDM Importer pops up because the report generated in LabVIEW is in the TDMS file format. TDMS is a binary file that requires an importer to make sense of the binary data and translate it into an Excel spreadsheet. As per this white paper, the appearance of the floating toolbar is expected behavior: http://www.ni.com/white-paper/5874/en/
To the best of my knowledge, you cannot get rid of the floating toolbar unless you uninstall the add-in, in which case you probably would not be able to open your LabVIEW-generated reports. However, as of Excel 2007, the toolbar is embedded in the "Add-Ins" tab instead of floating on your spreadsheet. You can see how the toolbar looks as of Excel 2007 in step 6 of this white paper: http://www.ni.com/white-paper/5885/en/
If there is a way to embed the toolbar in Excel 2003, it would be the exact same way you would embed any other floating customer toolbar in Excel. In other words, I don't think this has anything to do with the fact that it's NI's add-in. This is just the way Excel 2003 and earlier treats add-in toolbars. Someone on these forums may well know a way to embed it (perhaps a macro?), but you may have better luck contacting Microsoft. I'm not sure whether it's even possible for a user to embed the toolbar.

How can I create a array with all files from a directory

How can I create a array of files or varchar with all files from a directory?

I thought the example could be improved upon. I've posted a solution on my blog that doesn't require writing the directory list to a table. It simply returns it as a nested table of files as a SQL datatype. You can find it here:

How to stop prompt while opening an excel file in new window

hi all
i made one table in jsf and i am having two icons corresponding to each row one for open and one for save. on the click of open i am calling web services getting the excel file and opening it but it is happening only . when i choose to open option from the prompt which comes when i click on the link. how to remove that prompt so that on click of the open it should directly open the excel file. plzzzzzzzzz hepl

in the url of the new page that you are opening add --> &RetainAM=Y at the end.
Following points should be useful :
Suppose ,you have to open a new window from your page by clicking on a link or a button and after opening, when you click on any button in the parent page, if you are getting a session out error… try the following solutions:
1.     Add retainAM=Y in the destination URI of the button or link
2.     If you have the back button handling in your code, ensure that…
if (!pageContext.isBackNavigationFired(true)) is written instead of
if (!pageContext.isBackNavigationFired(false))
3.     Also ensure that the trasaction name is exactly same in both startTransactionUnit and end TransactionUnit
TransactionUnitHelper.startTransactionUnit(pageContext, "sameName");
TransactionUnitHelper.endTransactionUnit(pageContext, " sameName ");

Using Lab view ver 6,How can I read a cell of excel file right after I write to it

How can I read a specif cell of an Excel file using Labview VI.

Hi,
Attached is a LV6.1 VI which will read a cell.
It will be looking for a sub VI found in the example C:\Program Files\National Instruments\LabVIEW\examples\comm\ExcelExamples.llb.
The returned value is a string value but there is no reason why it couldn't be a number. Just connect a numeric to the type connector of the Variant to Data function.
Hope this helps.

Can I open a excel file from labview

I have a program who write temperature in a excel file and i want to open this file from labview .

This depends slightly on the amount of data you have stored within Excel.
You can use the "Labview Functions>>FileIO>>Read from Spreadsheet file.vi" which effectively reads all lines from a text file and converts it into a numeric array.
Alternatively, if your data structure in Excel is more complex than this, you can use ActiveX calls to Excel to retrieve it.
Use an "ActiveX>>Automation Refnum" control and select the Excel server class. This will then enable you to access properties and methods of Excel to retrieve data from specific cells and pages.
The attached example should help.

How do I create working hyperlinks in Excel files?

Hi there, I'm new to this so please don't over estimate my knowledge! I am trying to create an online file repository for a client. It is basically a website holding excel files that link to each other. The hyperlinks work on the website version but don't work on the blackberry bold test handset I'm working with. I was creating them in excel as web page hyperlinks. Can anyone please shed some light on why these don't work? Thanks Ali

Pages '09 ≠ Pages 5.01.
You have the bugs and reduced features of Pages 5, the version you recently installed.
Pages '09 should be in your Applications/iWork folder.
Use that instead.

Are you saying that you bought a used or second hand Mac? In North America an open box Mac usually refers to a display model used in a store.
There is mixed info on this issue. Some folks in the US have called Apple Care and requested that the iLife apps prebundled with this specific Mac be released from original owner's Apple ID so the new owner can Accept the apps into their Apple ID, with success. Folks in Europe report that when making the same request of Apple Care they are met with resistance and are unsuccessful.
YMMV
The sad thing is that if Apple Care will not release the apps, then the owner of a second hand Mac cannot even purchaase the apps on their Mac! To buy the apps with their own account, they would need to find an older Mac running at least OS X Snow Leopard 10.6.8 with a Mac App Store (MAS), that also has never had the MAS versions of the iLife apps installed on it.

How can I create more than one program shortcuts in LabView Installer?

I have builded 3 executable files in LabView Application Builder. I want to create an installer (using the same application builder) that can copy the 3 files to the same destiny directory, install the Runtime Engine and create (in the same program group) 3 shortcuts for the executables. Is it possible with LabView Installer?

The Application Builder does not offer this option. It is really intended as a basic installer builder. However, you can use other software packages to enhance your isntaller. There are many third party installer builders that you can use to modify the msi file which the application builder create for you. You might want to check one of those out and use it for your application.
