Download file stored in Database?

We are implementing a mini DMS in our application and need to
write and read files to the database. We are trying to figure out
if we can convert the byte array we get from the DB into a file
that the end user can save on the client machine.
Is this possible with Flex? I have heard no, but that Apollo
might allow it. What is Apollo?
Any ideas on how we could accomplish this with Flex3?

Apollo is what Adobe AIR was call in it's last version.
It's certainly possible to donwload this file from DB to
user's machine using Flex. And the bulk of the job would be done on
the server side, using Java/.NEt/PHP/whatever.
Flex would simply send a request using FileReference class to
a server side page and that page would read the file from DB as
byte array and write to the response. That would allow user to save
the file on his/her machine.

Access forms File stored in database

Can any body help in this
Call_Form('i:\test\fmb\entgrp');
here entgrp is the FMX file stored in Server which is mapped to i:
1 Now if i want to use this call_form
to call the file stored in database what is the syntax
2 and How to invoke this file from desktop using f45run
3 The File Stored in Databse like this is fmb or fmx
Thanks in Advance

When you save a Form to the database it is the FMB that you save and not the FMX. So you'll need to have the FMX on a file system and call it from there.
f45run recieves parameters such as userid=scott/tiger module=a.fmx
Check out the help to see the full list.
(P.S. Isn't it time you upgraded to a newer version of Forms?)

Downloading file from a database..

Iam writing an application which downloads a file from the database.The file lists will be displayed for the user. When he clicks a particular file, he gets a window with open, save cancel options
(i am using response.setHeader("Content-disposition","attachment; filename="+selectedfile);
     response.setContentType("application/octet-stream");)
I am reading the file from the database and storing it in the client system and then reading it from the saved location to view the downloaded file. But when it is viewed, the file is being copied to the temporary internet files folder and from there it is shown. So the file is in the two locations at the client side...
When user downloads it i am storing it in "c:/downloade/" directory and again reading from the c:/downloaded/" to display the file. But when I see the path of the file opened through its properties its showing the temporary internet file folder location..
"C:\Documents and Settings\.....\Temporary Internet Files\Content.IE5\2RED0V4P\v[1].jpg".
Please tell me is my procedure is correct, can we view it without downloading it to the client system. I am giving the code in my program..
FileOutputStream fs=null;

View file stored in Database in client machine

Hi,
I am using oralce forms Release 10.2.0.1.0 .
In my application , files (.xls,.pdf,doc,gif etc) will be stored in Database table as BLOB. I have to add the provison to view the file in client browser.
I tried using the webutil function to transfer file from DB to client and then from client to AS and showed the file using web.show_document. The issue with that solution is file keeps on created in AS server. is there a way i can programatically delete the file from AS, after showing using web.show-document.
Or can anyone suggest any other solution for the same.
Thanks in advance.

Hello,
There is no need to transfer the file on the AS if they are stored in the database.

Manupulating Excel File Stored In Database

Is there any way I can manipulate the excel file that is stored in the database as LONG RAW ?
I need to allow user to manupulate the excel file that is stored in database and accordingly fetch the specific data from that manipulated Excel File of Database.

Your best bet is to keep the data in tables and generate a new excel file each time. Search this forum on how to generate excel files.. Here are three techniques... I like the XML method..
1) OLE2
2) XML
3) CSV
I have also done this using webutil..
1) retrieve excel blob from db to client using webutil function db_to_client_with_progress()
2) manipulate excel file on client using CLIENT_OLE2
3) put excel file back in db using webutil function client_to_db_with_progress()
Sorry.. Just re-read your post and didnt notice the Long-raw part.. :)

Sound file storing in Database & accessing these files

Hi Friends
i have working on the project of Sound Recognization system
the requirement is that sound should be passed through mike input device & that sound should be stored in to database along with the user & password
for recognization & identification of user
But problem in storing the sound files in the database so how can i store the files into the database so please guide me.

brad103 wrote:
In my particular application, I process the byte array from the TargetDataLine. Then I save this to a db using new ByteArrayInputStream(soundData), soundData.length); where soundData is my byte[].
Am I correct that this will save the data in the relevant format (eg PCM_SIGNED, 8k, 16bit, etc), but the header information is not included? That's correct. Essentially, in JavaSound, that data has an associated "Format" object that was part of the line the data came from, would need to be given to any line the data was going to...and that format object is essentially a container for all of the header data...
And if so, then if I control the saving and retrieval then I can omit that step anyway as I know the format?You can omit the AudioSystem.write step and store the byte[] directly into the database...as long as you're capable of, as above, recreating the Format object that was originally associated with the data.
And my next question (digressing slightly, sorry umeshS), is that when using the tritonus gsm library and converting from above format to gsm, should I be using AudioSystem.write to write to an outputstream prior to calling AudioSystem.getAudioInputStream(targetEncoding, originalAIS) to convert encodings?AudioSystem.write adds the file header to the stream, and that's all. If you're using a "stream", you have to have the Format object in order to create an AudioInputStream, so there's no need to add the file header (and the file header will screw things up if you're not using the File or URL versions of getAudioInputStream)...
So, as a giant summary...
AudioSystem.write adds a file header, which will include format information. This should only be used if you're planning on using AudioSystem.getAudioInputStream(File f) to read the file the next time.
Otherwise, just save the data and the Format object associated with the data, so you can read it all back in later by building an AudioInputStream around your favorite IO stream.
And in retrospect, after explaining all of that...umeshS, the problem with the way you're doing it is that when you copy the file into the database, you're copying the file header. And then, because you're not using the "File" version of AudioSystem.getAudioInputStream, the system isn't handling the file header being there correctly.
You need to copy things into the database by creating an audioinputstream of your file, and then saving out the raw byte[] data. You can just call "read" on the ais a bunch of times and throw the results into your stream. Then, you can play it by pulling the data out of the database via a stream, and playing that stream by throwing it back into an AudioInputStream.

Where are download file stored before I select a save location? It looks like it starts the download before I choose a location.

I noticed that downloads start before I select a save location. Where are these files stored?

Firefox starts a download immediately in the background to the OS %temp% folder.

Size limit of access database with image files stored outside database

I have read 2GB limit on size of Access database. We are using Access 2013 database with fields that are data type attachment and storing attached images outside the database. Does the size of the folder that is holding these images count
in any way toward 2GB size limit?

Hi,
As far as I know, Access database limit size 2GB based on itself, not related to the folder size. Attachment data
type is similar to attaching files to e-mail messages. We need to control the Access database size is smaller then 2GB.
When a field is defined with the attachment data type, you can store one or more files for each record in it.
Attachments can dramatically increase the size of the database, but since the attached file is stored as a part of the dabatbase, you are not dependent on network drives being available as you would be if you inculded a hyperlink to the file. As a matter of
fact, feel free to backup the origainal file to other disk after you attach it to the database.
