Validate by file type?

Is there a way to validate file type for images uploaded via a web form?
We need to restrict files to .jpg, .png, or .gif.
Thanks,
Tim

Hi Mike!
I did not find your BADI in the system I currently have access (maybe a release or installed package problem) - but still I like to give you a hint.
There is a class CL_GUI_FRONTEND_SERVICES with the method FILE_GET_SIZE. At least for a path/filename to a local file you can get the attributes of the file with this function.

What are the differences in file types?

what are the differences in file types? HOW DO i CONVERT TXT TO A FILE TYPE THAT PLAYS MUSIC/VIDEO?

Every file on a computer is ultimately just a big collection of zeros and ones. Files with the .txt extension typically contain just text. If opened with a suitable program such as Notepad the text will be readable. Try to push the same file into a different application and you may get nonsense or crash the software. Well written software will attempt to validate the internal structure of the file it is given and reject anything it doesn't know how to handle. There are multiple audio file formats. Transcoding an audio file from one audio format to another is possible. Changing a text file into audio isn't possible unless it wasn't really a text file in the first place.

Webstart - Registering a custom file type

I'm trying to use a jnlp file to register a custom file type (*.flf) with Windows XP / Vista. I have added the following line to the jnlp file near the bottom (right by the main class tag):
<association extensions="flf" mime-type="application-x/flf" />On some sites I have found this listed as mime type first and extensions second and also with just a > no the end without a />. Neither seems to be working. I also found it listed inside the information section but this didn't work either.
Am I missing something blindingly obvious? For reference heres the entire jnlp file
<?xml version="1.0" encoding="utf-8"?>

<jnlp codebase="http://ukpcw032:8080/jclock" href="jFreelancer.jnlp">

That JNLP file is invalid. Try this variant..

Edit 1:
I used YAXV to validate the launch file against an XSD that is based on the DTD distributed by Sun. YAXV is freeware, and I highly recommend* using it to check the JNLP file(s) for any JWS launch that does not work as expected.

Validating a file type

Hi,
I have a form where files are uploaded to a server. I need to
prevent certain file types from getting uploaded (e.g, .exe etc.)
How can I validate the extention of the "upload_file" in the action
page when the temporary location of the file is gibberish. In the
action page, this is what is passed for the "upload_file" value:
/opt/jrun4/servers/cfusion/SERVER-INF/temp/cfusion-war-tmp/neotmp6417.tmp
Here's the form:
<cfform action="action.cfm" method="post"
enctype="multipart/form-data">
<cfinput name="upload_file" required="Yes" message="Please
upload a file.">
....

Thanks very much. I wrapped the entire thing in
<cftry>/<cfatch>.

How to filter the file type and size when uploadind files into APEX

Hi,
I was wondering how I can do to validate the size of a file, before moving it to my table ? I'd like to filter the file type, but for this one, I think I can use regular expressions in a validation process.
I don't know if there is a way to read the file size even before sending it into the temporary file table.
Thank you
Leinad

Hello Leinad,
AFAIK, you have to create an APEX validation (PL/SQL returns Boolean or Returns error text), which will query the file details from apex_flow_files table. Here you can get filetype and size etc.
So just validate and if any validation fails, then delete the file from apex_flow_files and riase error message.
Regards,
Hari
P.S. Please note that, if there are other apex validations on your page and if they fail, still apex will load the file into apex_flow_files table. So it's good idea to create a validation (PL/SQL) which will fire (condition) when inline validation errors occured. Make sure that this is the LAST validation on your page in sequence. And here you can write code to delete the file from apex_flow_files table.

FM to validate the file path on the presentation server.

Hi all,
              We are downloading a file on to the presentation server.
Is there any FM to validate the file path of the presentation server?
Suggestions are also welcome.
Regards,
Sreekar

You can call a class like a function module. See example below:
TYPE-POOLS: ABAP.
DATA: L_DIR TYPE STRING.
DATA: L_BOL TYPE ABAP_BOOL.
L_DIR = 'c:\windows'.
CALL METHOD CL_GUI_FRONTEND_SERVICES=>DIRECTORY_EXIST
EXPORTING
    DIRECTORY            = L_DIR
RECEIVING
    RESULT               = L_BOL
EXCEPTIONS
    CNTL_ERROR           = 1
    ERROR_NO_GUI         = 2
    WRONG_PARAMETER      = 3
    NOT_SUPPORTED_BY_GUI = 4
    others               = 5.
IF NOT L_BOL IS INITIAL.
WRITE: / 'Directory exists.'.
ELSE.
WRITE: / 'Directory does not exist.'.
ENDIF.

Hi praveen,
this may probably help you i think

Font file types in EPUB

Hi,
From iBooks Asset Guide I read that only TTF and OTF font files are welcome in EPUBs for iBooks and iBookStore. I wonder: is that mandatory?
I just made an EPUB3 that gather the fonts needed and one of them is a .suit file, not .otf nor .ttf file. It reads perfectly on iBooks, and it doesn't provide any kind of errors in EPUBCHECK. Would it be a problem when trying to deliver it with iTunes Producer ?
As a side question: do you use to just use iTunes Producer to "validate" your EPUBs seeking possible error message, w/o the intention of sending the file to Apple right after that?
Thanks!

Sorry for that, so here is my goal.
There is a folder contains may types of files: vi, lvlilb, txt and so on... I would like to make a VI that convert a given folder to LBB.
What file types can be placed insinde and LLB - is required for me to remove unwanted files
How to programmatically convert a directory into an LLB - I hope there is a VI what I can use as LLB Manager does for converting direcotries to LLB.
Yes you are right, the last question is not important...

Restricting File Types in the "Choose File" window

hi,
I am using struts *<html:file>* to upload a file.
When i click on browse button, one dialog box ie choose file window opens.
But initially, it shows All Files (*.*) in File types text box. But i want to restrict the user there only to select some specific types.
I use accept attribute of <html:file> tag and provide value like "*application/pdf,image/jpeg*".
But it is showing All Files in that choose file window.
can anybody help me on this?

there were a way of doing that but using the accept attribute in the input tag like <input type="file" accept"your MIME types">
but many browsers ignore this attribute and still show all file types.
another way to solve the problem is to validate the file selected after user clicks ok by java script code.

Set file type associations in Adobe Bridge for Photoshop CS6

Is there a way I can edit the registry so that in Adobe Bridge, under edit, preferences, file type associations, the jpg extension is forced to use the 32-bit version of Photoshop? I can do it manually, but is there a registry key i can export to apply it to multiple computers?

Yes, in theory, but it is generally not recommended. But that location would depend on what OS you are on. This video give the locations for the Photoshop files, Bridge would just be in a neighboring folder: http://tv.adobe.com/watch/the-complete-picture-with-julieanne-kost/how-to-reset-photoshop- cs6s-preferences-file/

Data Recover From Formatted Drive? What is the best program to use to get back Logic Projects and any other file type?

I was in the process of reorganising my hard drives so I could RAID them however I managed to corrupt one drive and had to format it which meant I lost all my Logic Files and some other files. I managed to save a lot of files (mainly video files) before I had to format the drive but I need a Data Recovery service that will not alter anything on the hard drive and will put all the formatted files (regardless of the type) back for me so I can get the rest of the ones I need.
Thanks in advance.

What about folders and such?
No. FS doesn't reconstruct folders. However, Data Rescue does, depending on how you use it. About the only thing in Data Rescue a Quick Scan ever seems to show you are files that are already live.
So that leaves you with a Deep Scan, or a Deleted Files scan. The first pass of a Deep Scan will attempt to retrieve folders and files, along with their original names. The second pass only looks for file patterns. Like recognizing a Photoshop .psd file. It will recover it, but give it a nonsense name. A Deleted Files scan only results in nonsense names of recognized file types; no folders.
What were you using File Salvage on? A hard drive?
Yes, though you can use it on a flash drive, or any other mounted drive.
At the moment it is estimating 289 hours remaining on a 1TB drive. Can it not go faster?
No, both of the software mentioned are slower than molasses in January. When you delete anything in Windows, its file table entry simply tagged as deleted. So to unerase them, the tag is removed. That's why it works to quickly and easily (assuming you haven't already overwritten the data to be recovered).
In OS X though, the whole idea of the underlying UNIX structure is all about security. It's not supposed to be easy to retrieve deleted items. When you delete items, their file table entries are erased. So the only way to find deleted items is to scour the entire drive for BOF (Beginning Of File) markers that don't have a matching starting block to anything that is in the file table.
Another question, half the drive was empty. Will it fly over that empty space or will it sieve through it incase there was some files stored on it?
If you use the Expert mode is FS, you can choose to do that:
