here du to that NI attackment error whith the following "The contents of the attachment doesn't match its file type"
i try to use .rar but same thing
any change in my Vi will be appreciated
please i need help in this
hi ?Q>

As mentioned above, Excel is out, because of the row limit.
What is the purpose of the file. Does it need to be read by other programs?
Writing 200 000 000 rows should NOT be done in ASCII or excel, but should be saved as a binary file. Much less overhead!

Programatically pick PowerView properties from Microsoft Excel 2013 file

Hi,
I have a requirement to programmatically read/handle PowerView properties like title, theme, background, font-size etc. from a Microsoft Excel 2013 file. Also I need to access the properties of the objects which are added on to the PowerView,
for e.g. properties of a table or a image added to the PowerView.
I have been looking for it since long, but no luck. Is there a way by which I can achieve it? Any pointers regarding this would be really helpful.
Thanks in advance.

Thanks Simon_Hou for the response.
As per your answer, PowerView is an add-on and hence it is packaged and properties can't be picked.
But, PowerPivot is also a com add-in still there exists a programming handle for it. We are able to pick several properties for PowerPivot using Interop.
For PowerView, I am able to see certain bin files getting created but am unable to pick any information from those.
(Bin files namely CustomProperties1.bin, CustomProperties2.bin, CustomProperties3.bin, CustomProperties4.bin, CustomProperties5.bin)
Is there any way by which we can pick certain properties for Power View as well using these files or maybe some other way?

Cannot able to save Excel 2013 file in Sharepoint 2007 document library

Dear All,
We have SharePoint 2007 intranet portal where in we have teamplace created for internal users to collaborate on documents.
Now we are having issues when using uploads Excel 2013 or Excel 2010 file on document library and try to edit the document.
Sometimes it doesn't allow to check out the file it say someone already checked out ..but when I try in my laptop its OK.
And some times when user opens the file it opens as non editable file and it does not take any changes.
Pls advise whether there is issue with SharePoint 2007 document library and Office Excel 2010,2013 files.
-- Regards Sandeep

The lock can apply in two places. Are you seeing the message in your browser or does it arise within Excel itself?

Regards, Hitesh
Saving the file as read-only does not mean you cannot make changes, it merely means it is recommended that you open this file as read-only. Also using 'xlWorkbookNormal' is incorrect since this is basically the macro-free xml format. Use the 'xlOpenXMLWorkbookMacroEnabled'
instead. Now as far as not allowing the user to make changes you will need to protect each worksheet, as well as protect the workbook. So something like
Sub ProtectWorkbook()
ThisWorkbook.Protect Structure:=True, Password:="test123"
Dim sh As Worksheet
For Each sh In ThisWorkbook.Worksheets
sh.Protect Password:="Test1234"
Next sh
End Sub

Using an existing connection in the Excel 2013 file in Power Query

Hi,
I've created an Excel workbook and a SQL Server data connection in this workbook.
When I open Power Query I cannot to use this created data connection.
In general, inside Power Query can I use a data connection created in the original Excel workbook?
Many thanks

Small file get extremely big after saving with Excel 2013

A file who is only 666Kb big with Excel 2007 is opened with Excel 2013. When I direct safe that file, the size increases to more than 6GB. Opening that file takes more than one minute. And Excel seems to crasch.(Not responding) The problem seems to be one
(1) sheet. when I delete rows the size of that file is increasing up to 16 GB. This means a less filed excel sheet, makes a bigger file.

Hi,
The issue seems happened in the special file and it may be caused by the conditional formatting, cell format, formula calculation automatic or macros,ect. Please see the thread which some communicators discussed:
http://answers.microsoft.com/en-us/office/forum/office_2007-excel/why-do-my-excel-files-become-huge/8235dc08-aa70-4a65-9892-b776790d79c5?page=1
Then, we may try the Mr. Ashish's suggestion:
=====
1. Identify the last filled up row of data and click on any cell in one row below that
2. Select from that row till the end and delete all rows
3. Do the same for columns
4. Save and close the file
5. Shut down MS Excel
6. Reopen the file
=====
If the issue still exists, please copy all the content to new/blank Excel 2013 file to test.

Automatic Linking from Excel 2013 to Word 2013 not working.

I use Word and Excel to create reports about certain real estate properties. When I have a new job, I just rename the old files and continue working. I also have active links from Excel into Word that are set to automatically update. I
used to use Office 2003 and all worked fine. Now in 2013, after I rename and convert the files to the 2013 file formats, the links do not update automatically. Here are my steps:
1. Copy the 2003 Excel and Word files to a new folder (these files link properly, where if I make a change in Excel 2003 it automatically flows to Word 2003)
2. Rename the Excel and Word files to the new job name and convert them to 2013 file formats.
3. Open the now 2013 Word file and do not update Excel links (as it is still linked to old 2003 file).
4. Break all links in Word 2013 to the Excel 2003 files.
5. Insert new active Hyperlinks in Word 2013 to the Excel 2013 files making sure that it is set to "automatic updates".
HOWEVER, now the links will NOT automatically update. If I have both Word and Excel 2013 files open and make changes in Excel, you do not see them in Word. You have to right click on the area and choose "Update
Links". Is there anywhere else that controls the automatic update features?

Hi,
I actually can reproduce this problem on one Office 2013 machine, but on the other machine with Office 2013, it automatically updates the link as it should.
You can create a new Word document and a new Excel file, copy the content from the old files to the new files, re-create the link, check if the link can automatically update.

Hi George,
I tried below solution but whenever I uncheck the tickbox, "Don't allow any apps to start",
click ok then reset my Excel, the app still doesn't work. The app I am using is still an image. And when I go back to the trust center setting, that tickbox is checked again. I tried unchecking it again and going to the settings immediately, the tickbox is
still checked.... Can you help?
Note: The Apps for Office under the insert tab is enabled or is not shaded in gray.
If it is, please go to Excel 2013 > File > Options > Trust
Center > Trust
Center Settings > Trusted
App Catalogs > Uncheck the "Don't allow any apps to start"

Unable to see field list in Excel 2013

Unable to see a list of fields to choose from when creating a pivot table. I only see the field table.
I have tried this ActiveWorkbook.ShowPivotTableFieldList =True and received the following message
We found a problem with this formula, We couldn't find a range reference or a defined name.

Hi,
Did the issue occur in the special file or all the Excel 2013 file?
If the issue occur in the special file, it might be caused by the file self, I recommend you copy/paste it to a new/blank file to test.
If the issue occur in all the Excel 2013 file, it might be caused by the Excel15.xlb corrupted. It is located in your Windows user profile which varies with OS (Documents and Settings or Users).
C:\Documents and Settings\Username\Application Data\Microsoft\Excel
C:\Users\UserName\AppData\Roaming\Microsoft\Excel.
Rename the file (Please note: If you don't backup it, you will lose any custom settings you may have made for Excel.) and then Excel will recreate it the next time Excel is opened.
If the issue still exists, please try to share us a sample file through One Drive, I want to test it.

Excel 2013 hangs while trying to open a file from network share

Hi,
I am having issue opening excel file from a network share. it happens randomly, the file opens and hangs abruptly. Nothing happens after that ( we can only move the cursor), if we click on the excel sheet we get a beep sound. after i kill the excel process
and open it again ,it works fine.
Where did the member use the Excel file? Local disk, SharePoint, File server, or network shared disk?
       Network shared file and sometime locally
Does the issue occur in the special file or every file?
      it happens randomly and the whole excel freezes. i have to kill the excel session.
Which Office version is the file created? Excel 2013 or early? If it is XLS format, please try to convert to XLSX to test.
   Network file server has office 2010 and the user is trying to open it in excel 2013
Does the file have some macros?
Yes, they have macros in some files
Does the issue occur recently? If it is, have you installed some programs or update before you encountered it?
       it happened before too.

Yeah. Attaching the error message from event viewer. We get file corrupt errors and below too.

Encryption Type in Microsoft Excel 2013 (XLS file)

Hello,
I am creating a password protected file of format Excel 97-2003 Workbook (.xls) using Microsoft Office 2013.
I have written a java program to read password protected excel file using POI API. I am able to read .xlsx file using this API, but I am not able to read .xls file. It throw error : org.apache.poi.hssf.record.RecordFormatException: Unknown encryption
info 4
Using same java code I am able to read .xls file if I use Microsoft Office 2010 to create this file.
As per POI API documentation:
Apache POI contains support for reading few variants of encrypted office files:
XLS - RC4 Encryption
XML-based formats (XLSX, DOCX and etc) - AES and Agile Encryption
I think in Microsoft Office 2013, encryption type has been change for XLS file. So I want to know that how can I solve this issue. Also please let me know how to configure Encryption Type in Microsoft Excel 2013 Excel file.
OS is Windows 8(64-bit).
Thanks

How do I write an excel file and check what the next empty column would be to put the data in?

I have somehow managed to write the portion of labview that prompts the user for a name. It checks a file to see if they are a new user or not and then assigns a number if they are. The program then acquires data that is to be put into a spreadsheet. Each subject will have ten trials which will have three columns. How do I get the information into the columns and then check each time to see which column it should go into (i.e. the next empty column for that subject). I have attached what I have thus far. I wrote this a long time ago and haven't touched it for some time so everything is a blur.

To perform those operations in excel you will use ActiveX. I will attach some examples of using Excel in LabVIEW and you can use these to do exactly what you want.
These three examples show how to manipulate properties, write to excel and read from excel. Let me know if there is more I can do.
