I made a discovery some time back. Just follow these steps:
Create a .doc/.xls/.ppt file in office 2003. Keep some test data in there and close the file. Now rename the file to change it's file extension to a random string, taking care that it is unassociated, like test.asdfghjkl etc.
Double click the file and it opens seamlessly in the parent application.
Now AFAIK, windows checks the file extension of the file and uses it to do an action, viz open an application and pass the file to it to open. Then how does the office suite manage to do this?
EDIT: How about the case when the extension is changed to one that is associated with another application. Is there a priority algorithm in place for handling that ?
Do you have the "View extensions for known types" option on?
EDIT: #Comments....
Yes, its a stupid/insulting question, but when troubleshooting a problem I have learned to assume nothing, and trust the users 0%.
BUT, I tried it, and you're right. Its stupid that MS has this kind of behavior, and it can only lead to security vulnerabilities, which led me on a search for your answer.
From the posts at http://seclists.org/fulldisclosure/2007/Jan/0444.html
"You have stumbled on an age-old
quirky behavior of Windows. Office
document formats are based on a
standard Windows container format, OLE
structured storage files, also known
as "docfiles". A docfile's name and
extension are irrelevant - the file
is, conceptually, a serialization of
an OLE object, and like all
serialization formats it contains the
identifier of the application that
produced it, in the form of an OLE
class id (in GUID format) in this
case. You can easily verify that it
doesn't work with the newer Office XML
formats"
Indeed it doesnt work for the 2007 *X file types, but 2K3 is still a problem. To solve this problem... Upgrade! =)
And here at security focus under TOC point 2.
So, there you go.
I can't seem to make this happen now, but I know I saw Windows reading XML processing instructions a few years back. Maybe that is what's going on?

I'm using a java method to download via agent my multipage dashboard to server file system. When I open the downloaded file I get an error "Excel found unreadable contente in "test.xlsx". Do you want to recover the contents of this workbook? If you trust the source of this workboos, click Yes."
When I click on Yes button, I have a warning "Excel completed file level validation and repair. Some parts of this workbook may have been repaired or discarded."
Data are perfect, nothing is lost, but file is delivered to end users and I can't let it so.
I've tried the same on another environment, where OBIEE 12 is placed, and unfortunately I encounter the same trouble.
I really don't know what to do. We have installed the patch "11.1.1.7.181016" that promises to fix java security trouble in creating the excel file, but with fully unsuccess.
Any suggestion would be great and precious.
Thank you very much.
There's a reason that 11g is outdated and has been replaced with 12c which itself is already on the way out and being replaces by OAS.
The ancient versions have issues that aren't fixed anymore and something that came out in 2013 is expected to not work anymore with other modern software at some point.
It's way beyond time for you to upgrade. And fast. The longer you wait the more problems you incur.
Update: If the bundle patch and the one-off patch 22934699 don't solve the issue then you will be stuck with it.
Alternatively you can switch to CSV for the export since looking at this question here and your other one all you're doing is data dumping.
With newly released Webi there's no way to manipulate reports with VBA like it was in DESKI era.
I'd like to know if there's a way for me to click a button with parameters in Excel sheet and get a report from the server?
I've been thinking of using the RESTful Web-services but it seems that there is a performance problem.
I also considered using a JAVA app in the middle using the SDK but it's not really satisfying as I add one layer.
Do you know if there's an other way to download a Webi report from and to Excel?
For this type of requirement, you'd normally use the OpenDocument feature. There is one thing that it won't do however, at least not for Webi documents, and that is deliver the output in Excel format (HTML and PDF are the two possible formats for Webi). In all fairness, the export to Excel option is only about two or three clicks away, but I can understand that this wouldn't be an ideal solution.
Another option is the Java SDK, which I would not recommend, as the ReBEAN SDK (the part of the Java SDK you need to interface with Webi documents) is deprecated and replaced by the REST SDK.
The REST SDK would be the way to go if the OpenDocument feature is not sufficient. Keep in mind that this would involve quite a few steps, each time sending a command to the WACS server and then decoding the answer. The steps would be:
Authenticate and get a logon token
Refresh the document (if necessary pass prompt values)
Export the document to Excel
Close the document
The REST interface is only supported on the WACS server, which should run on your BI4 server (unless you have a customised landscape). If it's slow, I would suggest looking into the root cause of this performance issue, instead of discarding the SDK altogether.
If you're going to use the REST interface, I would recommend opting for JSON to communicate through REST instead of XML. It's easier to read and parse.
A last option, which I wouldn't recommend, is LiveOffice. This is a separate product which allows you to embed contents from Webi documents into Office documents (most notably Excel). LiveOffice has always had its share of problems and has not received much love from SAP regarding much needed updates.
One final thought: the report will never appear in the same sheet, at least not without an additional amount of coding. Whatever SDK you end up choosing, you will always end up with an Excel file. If you want to show the results in the Excel file you started from, you'll need to code the steps to open the generated file, grab the contents and then copy those to your worksheet.
I work with an Excel add-in called SAP BEx Analyzer (BExAnalyzer.xla).
Unfortunately, the documentation of this add-in seems very incomplete and it's a pain to work with it.
I would like to know if there is a way to inspect such an add-in to see what objects/methods/function and so on it contains?
Many thanks!
In the current release of SAP Business Explorer (based on 7.30), the BExAnalyzer.xla file is unprotected so you are able to inspect it.
If you wish to delve deeper in to the BEx object model, it is worth adding a reference in your VBA Project to the two type libraries (BExAddin.tlb and BExApi.tlb) in the Business Explorer installation folder (usually located in \Program Files (x86)\SAP\Business Explorer\BI\).
I'm actually in the exact same boat with BEx. I haven't found any official documentation but a hefty amount of google fu gets me by. I've also had some luck pressing F2 in the code window when you have the SAPBEX.xla module selected and then picking the SAPBEX library in the first drop down. It will give you all the methods/functions/constants in the library which isn't documented well at all either but you can make some educated guesses and trial and error...if you have the spare time.
I have a system with an Excel spreadsheet template file which is used for invoicing. I would like the user to be able to click a button on an Xpage, which will then open the spreadsheet and enter the latest invoicing data in Excel. I don't mind if Excel is either the application on their machine or on the server, but my preference would be the application locally on their machine.
I've looked into Xagents, as I feel this is probably the answer. I know they can be used to create Excel but I have not been able to locate any mention of opening an Excel file, and entering data into specific cells.
Is this possible?
EDIT: you can use Apache POI for editing and creating Microsoft Office documents. This is a java project which gives you a handle to office documents and this can be used using java.
A good starting point can be the blog of Christian Guedemann from webgate:

(end of edit)
The only way I KNOW and tried to write data from Notes to Excel is exporting the data to an HTML page and setting the Content Type accordingly (e. g. as described here (there are a lot more resources available for taht):
http://www.dominoguru.com/pages/developer2010_xpagexlsexport.html
I am not sure if this is of help but it seems that this project can help you:
http://www.openntf.org/internal/home.nsf/project.xsp?action=openDocument&name=ZK%20Spreadsheet%20for%20XPages
As far as I can see this project can load Excel files from XPages - and then it should also be possible to edit the files.
Besides that the only solution I can think of is a Notes Agent that is called from the XPage. This agent can then run in background and do all the excel stuff. After running, the XPage can show a link to the Excel file. Actually this is the solution I would consider to implement - but maybe others step in with better answers here.
You don't want to introduce a dependency on Excel in your application -- wouldn't work with an iPad front-end. Rather have a look at the ZK Spreadsheet, it will fulfill your needs.
However if you have to have Excel, then you need a roundtrip solution: load the Excel from an URL (probably generated by an XAgent (?) and save it back. The saving back part is the tricky one. Normal HTTP doesn't allow that. What you need there is a webDAV capable server. Watch out for a project on OpenNTF soon (just clearing IBM legal) that provides webDAV.
However the ZK Spreadsheet looks much better for your needs.
I have a sample database at the following URL --> http://www.nnsu.com/nnsusite.nsf/%24%24OpenDominoDocument.xsp?documentId=B65507CB2DE15B3286257986005F061D&action=openDocument
Download the APCC.nsf. This will allow you to create/read a new EXCEL spreadsheet and then stream the resulting file to the requesting browser. There is not need to have EXCEL or office installed on the Server.
THe examples create a new workbook, but you can also store a "template" on the server or in a notes document and use it as a starting point and then save it to a document or stream it to the requesting browser.
With Apache POI you can read/write to a spreadsheet using data from the notes document the process is initiated from.
I have a method which downloads sharepoint documents to the local disk. I use SPFile.OpenBinary() method to get physical file, but it contains all fields of a parent DocumentLibrary. Does anybody know how to clear file (doc file) from these fields? I found only way to do it using Word interop library (method described here http://maxim-dikhtyaruk.blogspot.com/2009/05/trim-sharepoints-documents.html), but it doesn't fit my requirements cause it works only when Microsoft Office is installed on the machine...
You may want to read this to understand whats going on.
I do not know if this can be turned off or not, but it happens only with Word 2007 documents (docx).
You could do any of the following to turn this off:
Create a new content type and associate it with a document library. Use this document library from now on.
Look into some Open XML library or the Open XML SDK published by Microsoft.
This isn't a bug, it's supposed to be a feature! :-) Seriously though, you need to edit the Word document programmatically to remove these additional fields completely (I think even a content type will leave some behind).
For documents prior to Word 2007, you could use a toolkit like Aspose. I almost needed to do a similar thing once and would have used this product to do it. I'm sure there are other options out there.
For Word 2007 and higher, as SharePoint Newbie says, you should be able to use the Office Open XML formats to edit the document. Here's an MSDN intro article.
