How to configure file upload restriction by file extension?

Hi All,
I want to know if its possible to restrict the file upload for any file extensions in CM Repositories. For example, I want that the users can not upload .avi files. Can I configure that restriction?
Regards and Thanks,
Arnau Rovira

Hi,

No. A repository service is a standard pluggable service within the KM framework. Search for "repository service" on SDN for further details.
> can I copy the upload command

The upload command is the upload command is the upload command. It is not bound to any repository service.
Yes, you can try to extract all implementation classes for the actual upload command and create a new one under a new namespace and modify the interesting parts after decompilation. But be warned: Your questions signal that you are a beginner in the KM framework, and the things described so far are more in the direction "hardcore development"...
Hope it helps nevertheless

Hi all,
The file adapter it consists many operations like

4:ListFiles
So you are asking about Read operation
First you take one File Adapter-->Select Read Operation--->Give Incomming file Location ( In local system you can give like C:/temp/NewDir Or Unix Envornment like you can give /temp/NewDir)
After that you can give file Name like wich format it's incomming file name like CSV.txt or CSV.xml after you give Polling Intervels second or Mintued or Hour.You can select Native format or Define service Later once configure all those things the file adapter configration is done .

How to display file extensions

Hi,
I'm trying to get our Sharepoint 2013 server to show file extensions again and I've had no luck so far. I've been able to add an extra name column that shows the file extension (like ), but that name is not clickable anymore so I've ended up with one name
that's a link and the same name next to it. This doesn't look good, especially when the users pick overly long file names.
This (http://social.technet.microsoft.com/wiki/contents/articles/11161.how-to-display-file-extensions-in-a-sharepoint-document-library.aspx) seems to apply to Sharepoint 2007 only. I'm not sure which onet.xml file they mean and the default file has several
occurences of "Name=”Created_x0020_Date”", or how adding
Name=”File_x0020_Type”/> without an extra opening bracket would work.
I've also found and tried this solution: http://social.technet.microsoft.com/Forums/sharepoint/en-US/59c15eee-9116-4aa1-8d16-32cd361c9a2f/show-file-extensions-in-document-library?forum=sharepointcustomizationprevious
>>3. Edit the WebPartPages:XsltListViewWebPart so that the link contains the extension.
>>a. Open SharePoint Designer and click on the desired document library.
>>b. Open the View you want to change, which in most cases is "All Documents".
>>c. Find the line that looks like this:
>><xsl:value-of select="$thisNode/@FileLeafRef.Name" />
>>d. Edit the line to look like this: (the xsl:if tests to see if the suffix is not blank and then displays a '.' and the suffix)
>><xsl:value-of select="$thisNode/@FileLeafRef.Name" /><xsl:if test="$thisNode/@FileLeafRef.Suffix!=''">.<xsl:value-of select="$thisNode/@FileLeafRef.Suffix" /></xsl:if>
This doesn't seem to work with Sharepoint 2013 because the line <xsl:value-of select="$thisNode/@FileLeafRef.Name" /> doesn't seem to exist. Are there any other suggestions on how to get the file extensions to show?
Thank you.

How to set file extension?

Hello there,
I have added the ablility of saving the data in my program. I was wondering how do I restrict the file extension when the user wants to save the file?
What I mean is right now, when a user saves the data to file, they can choose the file name and the file extension. I do not want to allow them to choose file extension. I want to have a predefined extension, for example .usr or .dat.
I have seen this in many applications but I do not know how to implement this. I would appreciate it if someone could help me.
Thanks for your help!

How you are getting the fname from the user has an impact on how you do this, but not what needs to be done. What is required to have something that takes the fname from the user and parses it, extracting a fname. Once you have that, just append the extension that you want and save the file.

How to assign file extension and custom icon to executable?

Hi all,
I was reading an old thread about this issue:
http://forums.ni.com/ni/board/message?board.id=170&thread.id=116925
I need to try to do this. My application uses a custom file extension (i.e. .abc). Upon installation I would like to:
1. Assign My App and custom icon to the file class (extension .abc).
This could be done by manipluting the registry (http://msdn.microsoft.com/en-us/library/bb776856(VS.85).aspx)? This could be a problem with Vista s unless registry operations occur during installation any changes are placed in a VirtualStore, correct?
2. Enable the double-clicking of .abc file type to pass the data in the file to my VI (exe).
According to the File Handling Guidelines of Jean-Pierre Drolet (http://www.openg.org/tiki/tiki-index.php?page=File+Handling+Guidelines) the best way to do this may be using LabVIEW as an ActiveX server.
I know that when I build an executable (or installer?) there is the option to enable LabVIEW to act as an ActiveX server. This much I know I need to do.
I thought I would open this discussion again as others may be interested and there doesn't appear to be a completely clear solution available. Please do contribute where you can.
Cheers,
Battler.

How to register for ommand line event so that when a user double-clicks on a .abc file I can handle the opening of it?
This needs to work (the files need to open) not only when the application is closed but also when it's already open.
Anyone have ideas?
The solution to that is to implement a DDE server in your application (and add DDE entries to the registry on installation). There are still DDE functions in LabVIEW vi.lib\Platform\dde.llb but they are considered depreciated and have been removed from the palette, also because Microsoft is trying to tell everyone that DDE is depreciated and sort of unsupported too. But it is still the mechanisme to pass actions from the shell to running applications.
I hesitate to send you over to lavag.org where there have been some discussions about this years ago. If you go there you would do good to employ a friendly attitude. That board is run all by enthusiasts and idealists and they are all great folks but react not very friendly to people with an attitude.

How to include file extensions in contacts?

When printing contact sheets from the Print module I don't manage to have the file name inclusive of file extension under each thumbnail (e.g. Maria.jpg); so far I only managed to have the file name without the extension (e.g. Maria). Any idea how to do it?

F-
 
 I doubt it's impossible, but why would you choose to do this? I we know, perhaps another method may suffice.

How to Hide File Extensions in URL

Hello Again!
I've tried to edit my .htaccess file to hide file extensions in my URL, but nothing I try works. I get "Page Not Found" when I try to remove the .html from my pages. Here is the code I have used:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.html !-f
RewriteRule ^{.*}$ $1.html
I've also used
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^{.*}$ $1.html [L,QSA]
Neither worked.
Any thoughts would be helpful! Thanks!
K

When you save the document there is a check box in the save window that gives you the option to hide the extension. I've checked this for both Pages & Word. I can't be certain that all applications give this option.
You can of course delete the extension name from individual files already on your computer by selecting the file name as if editing the name and just deleting the extension part of the name.

How to hide file extension on finders symbolic view?

When I switch the finder's view to symbolic the files view turns to an icon or minimized first page of the file's content. In some cases the file extension is displayed at the bottom of this symbol. E.g. files of type PDF always show the 3 letters PDF at the bottom of the small preview image. Files of type PKG don't show it.
Is there a way to change this behaviour? Changing it in the finder's prefrences only affects hiding or showing the file extension in list view.
Thanks for any advice!

I tried it and it didn't look like it took effect. I switched folders and cam back to the first one I looked at and the extensions were showing.
It may just need time to redraw the view.

How to strip file extension off a filename NSString ?

To retrieve file extension from NSString, we use "pathExtension".
To retrieve the filename from NSString without the extension we use ?

9 views any nobodies helping ?
Oh well...
I've created this function to achieve this:
-(NSString *) returnfile_name_without_theextension:(NSString *)filename
NSString *filename_extension = [filename pathExtension];
NSInteger filenameextensionlength = [filename_extension length];
NSInteger filename_length = [filename length];
filename_length = filename_length - (1 + filenameextensionlength);
return [ filename substringWithRange:NSMakeRange(0, filename_length) ];
Hope someone might find this useful.

How to configure file upload restriction by file extension or size?

Hi,
I have recently configured a 7.0 portal with the BI-JAVA component. A feature for the BW reports and IP iviews is that a user can add comment and even upload a file to a default BI repisotory. It is easy to restrict access to users by means of ACL, but i also want to avoid users from uploading anything apart from *.PDF. It would also be nice to restrict in file size (otherwise it is easy to just rename a file you are uploading). Is there someting available to implement this in the portal?
I have read some threads that state this is not possible by default and only by creating a custom repository service or just hacking the upload command. These threads seem rather old and i dont know if the presented solution is still valid. Does anybody know if SAP is to delever a solution for this? (perhaps in an enhancement pack?)

Hi,
    Is there someting available to implement this in the portal?
    No. You have to develop this functionality.
    Have you read this blog: Restricting The Size Of The File To Be Upload in CM Repository ?

There are two ways to use the Os command in the file adapter.
Lets talk about the sender File Adapter.
First: Run operative system Before Message Processing
Whenever any operation needs to be performed uppon the source file Just before XI picks it up.
e.g. Calculate any hash code, backup the file to a given location, create a log at os level, etc...
... After Message Processing
After Xi has processed the message, you can trigger a new os level command:
e.g. Trigger a mail, check if the archiving was successful, etc.
> What is the default path where it is actually runs this OS command?

Theres no default path, you assign the desired path in the Comm Channel configuration.
