How to validate File extension.

Hi all,

thanx
Rakesh

Hi,
If you are using upload FM, fill up the following parameters..If you want to filter the data by certain extension.
Hope this works...
FILETYPE                        DAT
ITEM
FILEMASK_MASK                   *.xls
FILEMASK_TEXT                   *.xls
FILETYPE_NO_CHANGE              X
THanks,

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.

Hi
use these functions
RIGHT (Text, Number)
Return X characters from the right
RIGHT(“The Quick Brown Fox”, 5)
n
SEARCH(Text1, Text2, Num)
Returns the index of Text1 within Text2,starting the search at index Number
Formula should be
right([Name-column],search[".",[Name-column],1))

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.

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 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 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 validate File Path given for upload

Hi All,
I am trying to upload a file using the File Upload Control. I have already bound the data and resource property with the context attributes. Can someone please suggest that what can be done to validate the file path? For eg. if i enter "abcd" in the file path and click a button for uploading the file. My application simply "HANGS UP" without even reaching the code what i have written on action of the button.
Is there any way to permit the user to enter the path only through Browse button and not manually? Please reply ASAP.
Thanks and Regards,
Smriti

Hi Smriti,
Have a look on the Following Links... which clearly briefs what is the use of FileUpload UI and how it works behind the screen...
<a href="/people/dagfinn.parnas/blog/2004/08/15/inputfile-how-to-hide-the-plain-browse-button you about the how the FileUplaod UI is being built.</a>
<a href="/people/dagfinn.parnas/blog/2004/08/15/inputfile-how-to-hide-the-plain-browse-button more stuff on FileUpload UI</a>
<a href="http://support.microsoft.com/default.aspx?scid=kb;en-us;892442">How the FileUpload UI interacts with the local system</a>
After going thru above post, you can identify that the inputField is being declared as FILE type (like <input type="file" >), and you would also noticed the cause for your error in the last link which I have specified above, and what microsoft also recommends for it as a solution to show an alternative message in place of the blank screen...
Hope now you would be clear...why your method is not being invoked..
Please revert back for futher queries... try to come soon with an alernative solution...

How to preserve file extension on rename?

So, my little First World Problem:
On Snow Leopard I was very used to pressing enter and renaming a file by simply typing a new name while preserving the extension. Now I've noticed that in Lion when you press enter and start typing the new name, you'll have to type in the extension too. Is this changeable?

No, the behavior in Lion should be the same.
I just tested it and "return" highlights the name and leaves the extension.

How to create encrypted File Extension??

hi Folks
i'd ilke to ask how to create file extension and how encrypt this extension??
to make my question clear suppose we develop a word proceesing Application i would like this Application produce let say ".kad" when saving it and how to make this extension ".kad" encrypted meaning that we couldn't open the file unless my Application is existing.
can anyone help me or give a tip to start of the way!!!!!!!!
thnx

Hi eng_kadry,
if a little confusion is enough for you can use just a binary format, i.e. do not store readable text, but compacted binary information.
If you really need to encrypt your data have a look at JCE (Java Crypto Extension) which provides various encryption algorithms.
Note: You can't encrypt a file extension you encrypt the file. You can't prevent anybody opening the file with a hex-editor, but if you use binary or a really encrypted format he/she won't be able to make any sense out of it.
Another note: Be aware that your program will always contain everything it needs to decrypt the files, so if anybody goes through the pain of decompiling your program he/she will be able to use the files and you can't prevent decompilation

Windows 8.1 File Extensions and Show Hidden Files Always showing

Dear sir,
It's been an on and off problem for me since my windows 8.1 sometimes like to show it all whether it's the extensions of the file or even the file itself and it doesn't accept my command on not showing it. I have a bitdefender 2015 always up to date so my
guess is that could not be a virus please help.

Hi,
How about uncheck file extension option? In addition, follow the screenshot below and make your settings same with main.

Dreamweaver as custom editor for other file extensions

So, I'm working on a project that requires me to work on some
files with non-standard extensions. Namely, I have some text files
that have a .cm extension, and I have some code files which have no
extension at all. I am connecting to my file store via an FTP
"site" set up in Dreamweaver.
Under preferences->filetypes/editors, I set up ". .cm" for
those two cases, and had selected "Dreamweaver" as the primary
editor.
The files open just fine, and I'm able to edit and save them,
and when I do, the files get "PUT" back up to the FTP server as I
want. However, what I've noticed is that the first time I edit one
of those types of files, and save it, now, from then on in that
session of Dreamweaver, any time I de-focus the window and then
come back to it, the IDE initiates another PUT action of the files
in question, even if the files are unchanged.
However, if I go back into preferences, and remove the
"Dreamweaver" as the primary editor for those two extensions, and
leave that list blank, Dreamweaver still is able to open up the
files as I want, but this weirdness with FTP putting and the
window-focus goes away.
Anyone have any idea why?

Change File Extensions (Newbie)

I want to exchange .html extensions to .php in a folder. Actually, someone showed me how to it with AppleScript. However, someone else told me about Autmator, which looks like a really cool tool. Unfortunately, I can't figure out how to change file extensions with it.
When I open Automator, I get a little window that lists seven scripts or functions, beginning with Change Extension. If I right-click on Change Extension and choose open with Automator 2.0, I get a bigger window ("untitled") with a long list of actions on the left. Again, I click Change Extensions.
On the right is a little box titled "Ask for Finder Items." It includes three options:
Prompt, Start at and Type. But I don't know how to precede. How do I indicate what file extension I want to change from or to?
I first asked about Automator on a thread at
http://discussions.apple.com/thread.jspa?messageID=9490359#9490359
Someone posted an image that shows a second window where you type in the file extensions you want to work with. But I can't figure out how to make that window appear on my program.
Thanks for any tips.

Here's a simple solution. Select all the files in the folder by navigating to the folder in the Finder. With the files displayed press COMMAND-A to select them all. Press OPTION-COMMAND-I to open the Inspector window. In the Name and Extension field change the extension from .html to .php. Close the window.
