I'm not sure which version of LabVIEW you are using, nor what some of the VIs are in your code. However, if you have a recent version of LabVIEW (say 2012 or later) and have access to the Report Generation Toolkit, you will have a much easier time working with Excel.
In January of this year, I posted an Example to replace the Excel example that ships with LabVIEW. However, I'm not very good at finding my own posts on this forum, so I can't easily point you to it. However, if you do use the Report Generation Toolkit and do not use ActiveX calls, you will find that the functions to open and close Excel Reports tend to work without significant problems (there is a glitch, that I've reported, whereby if you "manually" close the Excel Workbook and then try to close it with the Report Generation's "Save Workbook", it will actually delete the manually-saved Workbook for you)(there is a "work-around" until NI fixes this ...).

Automatically open, save and close excel?

I need import data from Excel to SQL.
Now, I use tSQL to directly read the excel files and transform to the SQL table.
As the user Excel is not a good format for SQL to read, I need use formula to transform the excel to be a SQL readable format.
Now, I add a sheet to copy the data from the sheet which user input the data and then ask the user to copy the excel to a specific location for import.
However, this will make the data in the excel double and result a large excel file.
I am thinking if it is possible to create a excel to use formula to copy the data from another excel.
Then, I need find some method to open that excel, let the content refresh from the source excel, save and close it.
Then I can directly use this excel for data import.
Is there any simple way to do so? I don't know marco much...
Ivan

No formula could do this (Automatically open, save and close excel).
You need to recode a marco or write a macro. Why donot you ask in msdn?
http://social.msdn.microsoft.com/Forums/en-US/home?forum=exceldev&filter=alltypes&sort=lastpostdesc
example:
Sub auto_open()
Application.OnTime Now + TimeValue("00:01:00"), "wswx"
End Sub
Sub
wswx() If Not ThisWorkbook.Saved
Then ThisWorkbook.Save
ThisWorkbook.Close
End Sub

Open file in main vi, write in subvi and close in mainvi

Hi,
Im opening a file in the main vi , passing the reference number to the
write to text file which is located in the subvi and passing the refnum
out from this vi to the main vi again to close the file.
But, I always have only the last value of the measurement stored.
Im getting data from the serial port.
what am I doing wrong?
Can someone help me.
Thanks and regards.

You probably have forgotten to set the "Write" function to APPEND the data to the file.
This has nothing to do with where you are writing the file. Check the inputs for the write function and make sure you set it up to append.

DMS - Unable to open and Close Excel docs

Since updating to SP3 :
1. Excel documents, when opened, show as blank in Excel.
Activity Log show as Opened
2. Closing the Doc does not return doc to library
Activity Log shows nothing .... ie - the doc is still open
3. I need to Reset the doc to do any further actions on the Doc
4. After Checking out the Excel Doc, I opened it
Made no changes to the doc
Closed it
GroupWise kicked up an E511 Error during the Close - Unable to REturn
doc to Library
I wasn't in DMS mode while editing the doc !!

It's even worse than I thought
On a very rare occasion, opening the same problematic Excel doc works
But most of the time it does not
Per my previous post, this occurs on both T/S 2003 (with office 2003)
and T/S 2008 R2 (with Office 2010)

Open, Write and Close the file using Powershell

Hi All,
I need to create/open a file and write some data into it and close that file.
Could anyone please help me with this.
Thanks.

You don't need to explicitly create, open, or close a file in Powershell. Here are some ways to write to a file, in addition to New-Item:
$text = 'Hello World'
# Create file:
$text | Set-Content 'file.txt'
#or
$text | Out-File 'file.txt'
#or
$text > 'file.txt'
# Append to file:
$text | Add-Content 'file.txt'
#or
$text | Out-File 'file.txt' -Append
#or
$text >> 'file.txt'
Grant Ward, a.k.a. Bigteddy
The problem with Out-File is that it works like the console. When text is output, it will be truncated if it is wider than the default. So if you are looking for something where you need to store lots of long strings, then you may want to choose a different
route, or ensure than you specify a width for your output.
http://technet.microsoft.com/en-us/library/ee176924.aspx
For example to get 200 characters of width:
$text | Out-File
'myfile.txt' -width 200
I do not know for certain if there is a limit to how wide it can be. I also assume the default is the standard console width (80 characters I believe.)

How to convert excel data into OTF and FAX

Hi All,
We have a requirement where in we have a smartform output (OTF data) converted into PDF, and an excel sheet, both being sent as email attachments.
Now, we need to send the content of both the attachments as FAX.
Since smartform output was OTF convertible, FAX was being sent using 'CONVERT_OTF_AND_FAX' FM.
Can you let me know, if there is a possible way for manipulating the data that is converted to EXCEL, as OTF, and then FAX it?
Or else, please suggest me an alternative way to FAX normal data (other than using 'CONVERT_OTF_AND_FAX').
Thanks in advance,
RAVI

Hi
I'm having this very problem.I'm trying to open write then save and close and I'm having trouble with the latter. Right now when I run by VI twice, I get a message saying the file is already open and whether I want to open it again, meaning that it wasn't closed in the first place. Is there a Save option rather than a SaveAs option
I tried the VI uploaded by aeastet but I couldn't get it to work.

How can I write a file and fill it in periods?

Hi Every body!
I need help with this.
I have my aplication(power quality analiser),This VI obtain several varibles and make a lot of calculus and operation, to obtein others parameters in real time so my problem is Save the acquire data and calculus data into a file (similar as a report) every period(custumizable for the user in time units)
I mean make a only one file wich is write every period continuously , e.g. Start my principal VI and this event start the write of file, past one period,make other row or colum into the same file and continue that way until we stop the principal VI.
How can I make that?
Thaks very much
Best Regards

Hi,
assuming you have your trigger (notifier or just periodically) you can append the data to a single record.
Open the file, set the file position to the end, write the data and close the file.
Hope this helps

Converting OTF to EXCEL or PDF to ECXEL and sending Excel through mail

Hi ,
I need a solution for Converting OTF into EXCEL or PDF into ECXEL and sending Excel as a attachment to the mail.
In my current Program I am getting OTF data from script and converting into PDF using Function module ' CONVERT_OTF'
And sending PDF as a mail attachment using Function module 'SO_NEW_DOCUMENT_SEND_API1' it is working fine but
My current requirement is I need to send Excel as a mail attachment instead of PDF.
Hope it is clear for you, please give me solutions with sample code..

Hi!
Because OTF is not a grid, like Excel, and PDF can also contain anything, I think it is not possible to convert an OTF, or PDF into an excel spreadsheet.
You can convert an ALV into excel and send it via email.

Force file to write into Hard disc

Hi
I am using Filewriter to write a XML file which is generated in my program flow to write into HD. and I will pass the file path to a EJB for further processing. The problem is EJB throws XML format error . The file is not written immediately to HD even I flush it.. Please help..

As long as the writer and the EJB are on the same computer. The data only has to be written to memory. The data is written to memory as soon as you call flush.
Is it possible the EJB starts to read the data before the file has finished writing?

Read data from Excel and write into oracle database

Hi
I want to know how can i read data from excel and write into oracle database using java.Kindly help me out to find a solution.
Thanks and Regards
Neeta

Hai,
I am suggesting the solution.
I will try out and let u know soon.
Make a coma separated file from your excel file.
Assuming that your requirement allows to make a csv file.
This file may be passed as an file object to be read by java.Using JDBC you must be able to populate the data base.You can also use String Tokenizer if needed.
You do not want to go via sql Loader?
For reading the excel file itself do you want java?

Automation Open and Automation Close (Excel)

Hi
I am using ActiveX to write and read from Excel.
I am writing a program which a case statement is involved. When the boolean is true, the program in the case statment (View Result.VI) will open Excel and display the last save filename file. I run this program individually and not part of the main.vi program.
It displays the filename but once I close the file, the Excel also closed which I don't want it to do that.
I run my Main.vi (together with the View Saved Result.vi) and when I want to view the result, the program open Excel, but then, the screen hang and does not load the Excel properly. But when I run the View Saved Result.Vi, it does load properly.
I was wondering should I use Automation Close f
or every Excel workbook, worksheet or Invoke nodes which I have used in my program.
Please look at my JPEG file for understanding.
Thanks,
jun

I would not call Automation Close for each one. Once you call Automation Close, Excel will exit. That's just how ActiveX is built to work. As long as you want to leave the application open, you shouldn't close the ActiveX Automation controller.
I would actually suggest gettings the LabVIEW Report Generation Toolset for Microsoft Office. I have found it to be extremely helpful and it's actually quite easy to do what you're wanting to do with this Toolset.
