How to create a New Excel File programmatically

Hi !
I am documenting acquired data continuously in an excel file, what I need to do is to create a new excel file automatically when the size of the previous file exceeds a certain limit lets say 1MB.
I have tried using the simple 'Create/Open File' function and the 'Write to Spreadsheet File' function to create the new excel file. I does create a file but when I open the file it says the format of the file is not what you have opened it with.
Also when the new file is created, three new worksheet are to be added programmatically with pre-defined worksheet name and also Column headers for each of the worksheet are to be added.
I am also using 'Labview Report Generation Toolkit for Office'.
Regards,
Reeves

@ Aldo A
Thanks for the reference to tutorial, I didn't know about them. They are useful in general but unfortunately they don't answer the problem of creating an altogether new excel file programmatically.
@ ben64
The template thing simplifies the issue of formatting the new file. But I am still working on the new excel file creation challenge.
Let me put my problem in a different way.
Certain data is being acquired continually and is being written to a certain excel file, when the size of the file exceeds lets say 1MB the program should start saving the data in a NEW FILE instead of the previous file.
I have attached the VI to explain what I am trying to achieve here.

How to create a new txt file on the hard disk?

Which method in which class should I use?

there are documantatiosn and tutorials :
createNewFile :
"Atomically creates a new, empty file named by this abstract pathname if and only if a file with this name does not yet exist. The check for the existence of the file and the creation of the file if it does not exist are a single operation that is atomic with respect to all other filesystem activities that might affect the file. This method, in combination with the deleteOnExit() method, can therefore serve as the basis for a simple but reliable cooperative file-locking protocol.
Returns:
true if the named file does not exist and was successfully created; false if the named file already exists"

Hi,
Create similar kind of joins which you make after importing physical tables from db.
There is no difference in making joins in the excel. (both physical and BMM layers).
But always remember there are many limitations for having excel as database.

How to Append an existing Excel file?

I am using the jexcel api to write to a new excel file. Each time i run my program, it creates a new Excel File by the name i give it. my code to create the excelFile is as below:-
File excelFile=new File(workDir+"\\"+fileName+".xls");
WritableWorkbook workbook = Workbook.createWorkbook(excelFile);
After this code i write some data to a worksheet in the above mentioned excel file. But my requirement is that I want to create the excel if it does not exist, and if it exists, then the data should be appended to the worksheet in the existing excel file. At present it creates a new excel file and does not append it.
How can it be done? does anyone have any suggestions as to how can i tackle this problem? please suggest something.

There is no ready-to-run example, as you are searching for, available.
This has several reasons:
- It depends on the version of Excel. Examples for Excel 2007 might not work with Excel 2010 for instance.
- No one just wants to open Excel without doing anything with it.
The second point is something, i want to ask you:
Why do you want to open an existing Excel file at all? What is it, what you want to do after opening it?
If you have LV/C/C#/VB examples doing what you are looking for, why do you want to have it in TestStand directly, so NOT using existing code (saving time and effort) and basically re-inventing the wheel?
ActiveX is an interface for remote controlling and embedding applications with/in other applications on Windows systems. It is a PROGRAMMING interface.
So naturally, examples and tutorials exist for programming languages. Those examples are easily converted to TestStand sequences with a basic knowledge of the programming language and TestStand. Providing links for such tutorials/examples is a valid way to give support to fellow developers because we expect the fellow to have that basic knowledge.
If that knowledge is not present, i highly recommend to fill that gap.
just my 2 cents,

Opening new excel file by righ click produce worksheet name in french

Hi,
I am using Office 2010. I have strange problem. All my language setup is English. Though when I create a new excel file using right click options. It does create a new excel file with work sheet named in French by default. I see following three worksheets:
Feuil1, Feuil2, Feuil3.
How can I change this to English name so everytime it creates work sheet names as Sheet1,Sheet2,Sheet3?

Do you have a language pack installed? I assume your computer language is set to French?

How to create a data load file from Excel !!!

Hi All,
I'm new to HFM and would like to load data into an HFM application. As I have an Excel file with all the data. When I'm directly loading the data it throws an error saying "No section has been specified to determine if this is data, description or line item detail". How can I convert this excel file into proper format (.dat) file understandable by HFM ?

There are several ways to get this data into HFM.
1) FDM - best option if you have it
2) Webforms/Data Grids
3) HsSetValue formulas in Excel
4) DAT file loads
5) JVs, etc
If you wish to use DAT files created via Excel, you will likely want to use Excel VBA macros to create your DAT file to load. We do this on occasion for special projects and it works quite well. What you can do is set up an Excel file with your data inputs to look however you want, then link your POV members and amounts to another tab (we commonly call this the Export tab and it is set up in an HFM-friendly format).
Create a macro to write a DAT file to a specified location using data from the Export tab. The DAT file will need to be formatted as below. For a specific sample, you can extract data from your HFM app and see the format.
!Data
Scenario;Year;Period;View;Entity;Value;Account;ICP;Custom1;Custom2;Custom3;Custom4;Amount
Scenario;Year;Period;View;Entity;Value;Account;ICP;Custom1;Custom2;Custom3;Custom4;Amount
Scenario;Year;Period;View;Entity;Value;Account;ICP;Custom1;Custom2;Custom3;Custom4;Amount
Scenario;Year;Period;View;Entity;Value;Account;ICP;Custom1;Custom2;Custom3;Custom4;Amount
Scenario;Year;Period;View;Entity;Value;Account;ICP;Custom1;Custom2;Custom3;Custom4;Amount
Brush up on Replace, Merge, or Accumulate load options in the HFM Admin and User Guides, then upload your new DAT file.

How can I create a new excel workbook only with labview

Hi everyone...

Someone knows?

You are not using the correct mechanism. Pull up the Example Finder in LabVIEW, click on the "Search" tab, and enter "Excel". Look for an example called "Write Table to XL". Use this as a starting point for creating new workbooks and adding data to it.
Note: on disk the example is at <LabVIEW install directory>\examples\comm\ExcelExamples.llb.

How to create a new session in JSP file

Usually a child IE window uses same session with parent window. Dose someone know how to create a new session when creating a new IE window by clicking a URL in parent window? The web page is writen by jsp file.

I am not sure of your question. Are you wanting to have 2 Session objects (one for the parent window and another for the child)?
A session is usually created once per client and is stored on the server the session id is carried around in a cookie or a URL rewrite so that everytime the user submits a page you will be able to store/access information.
// this will create a new session object if one doesn't already exist.
HttpServletRequest.getSession( true );
Hope this helps

Automatically create new Excel file from template using data from a selected row in a separate Excel file

I am fairly new to Macro and VBA in Excel. I am trying to reduce the amount of work involved in a task that is performed often in our office. Currently, the task involves using 2 separate Excel files. One file is a tracking sheet and the second is the document
that gets sent out to the client. The second document has all the same information that is inserted into the tracking sheet. What I would like to do is have the information that is in one row on the tracking sheet populate into a new excel file that is created
automatically from an existing template.
I have been able to make this partially work. What I have been able to achieve is have the cell that is selected in the tracking sheet (the description field) copy into the new file that is created from the template that is on our server.
Sub NewRFI()
' NewRFI Macro
MsgBox Selection.Address(ReferenceStyle:=xlA1, _
RowAbsolute:=False, ColumnAbsolute:=False)
Selection.Copy
Workbooks.Add Template:= _
"template file path goes here"
Range("C14").Select
Selection.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks:= _
False, Transpose:=False
Range("C14").Select
Application.CutCopyMode = False
End Sub
What I need to do is get the rest of the information from that same row in the tracking sheet to copy to the new file as well. The other information includes the document number (one cell to the left of the selected cell), who it is from (one cell to the
right of the selected cell), and the date (two cells to the right of the selected cell). As stated, this information is all in the same row on the tracking sheet. Each piece of information needs to be copied to a certain cell in the new file and I do not want
the source formatting to be copied to the new file.
Ideally, I would like it to operate like so: select the first cell in the row (in this case would be the document number field). Then click a button to run the macro that will then copy the information from that row in the tracking sheet to specific cells
in the new file that is created from the template.
This process will save us from having to either manually copy and paste the information into the new file or re-type the same information that is already in the tracking sheet.
This is probably a simple thing to do but it would be great if anybody had some insight on this issue. Thanks in advance!

Try code like the following. You will have to change the target cells (D25, F1 and H4) to the ones you want, I just used some arbitrary cells as example.
Sub NewRFI()
Dim rngCell As Range
Set rngCell = ActiveCell
MsgBox Selection.Address(ReferenceStyle:=xlA1, _
RowAbsolute:=False, ColumnAbsolute:=False)
Workbooks.Add Template:="template file path goes here"
Range("C14").Value = rngCell.Value
' Change the target cells as needed
Range("D25").Value = rngCell.Offset(0, -1).Value
Range("F1").Value = rngCell.Offset(0, 1).Value
Range("H4").Value = rngCell.Offset(0, 2).Value
End Sub

How to create a new user id in OID for Oracle Collab suite File System

Dear Friends,
I want to know how to create a new user id in the oracle internet directory where i can use that user for the new subscription of the oracle collabration suite file system..
Please do the needfull and thanks in advance...
With warm regards
R.Prasad

Hi!
The way you suggest should not be used.
A CS user will be created as a normal OID user and will receive the CS attributes in a different subtree later during the provisioning.
For creating CS users use oesuser and uniuser. Files provisioning will work in a different manner anyway.

Whoa! Do you know what you're doing? Do you have permission to write on that URL? Or does the pathname parameter you passed on File is correct? How about let the server-side handle the creation of file for you by just requesting it? Do you know how to create a server-side Java program (e.i. Servlet)? Umm.. There's a Java tutorial for this for you to get started: [Reading from and Writing to a URLConnection|http://java.sun.com/docs/books/tutorial/networking/urls/readingWriting.html].

Finder doesn't find new excel files

I run an online business and we store customer information in Excel files (Office for Mac 2011). When I search for names in finder, it only shows the files from 2011 or older. New Excel sheets (one is created each day for the days orders) are not found. I have one open right now with the name Trevor Alin. When I search Trevor Alin in Finder, it returns only an old sheet from 2011, it won't show todays file. The same is true for files from months ago.
Is there anything I can do to ensure finder searches new excel files?

Console is just a log reader…
/Applications/Utilities/Console
You are probably thinking of Terminal
/Applications/Utilities/Terminal
I think you may need to post to Launchbar's support unless someone else can help, I don't use it & don't know if it only uses Spotlight's index for finding items.

Does Spotlight find the items now? If it does better than Launchbar you will need to look at how to refresh LB's index.
