How can i Store rtmp streaming into local File System?

I use socket and netstream.appendBytes to receive and play flv frames.
now I got the BytesArray,but how can i store them into local File?
FlashPlayer can't use Air File APIs.

This is by design. Content on the Internet does not have access to your local filesystem. We offer Local Shared Objects (LSOs) for storing small amounts of information, but this would not be suitable for scraping a video feed to disk.

How can I store and retrieve a Word file after it's been converted to a pdf?

How do I store and retrieve a Word file after it's been converted to an PDF? My file has been trapped in PDF"hell" assigned to a folder that cannot be opened or read, but when deleted, also deletes the original Word file...

I think we need some more info here like, how are you converting to PDF. This is the Reader forum and it doesn't convert files to PDF.

How Can i Store photo (image) in column of table

Dear Experts,
I need to store a employee photo in column so how can i do tha same.

This assumes that the images in question currently reside on the database server. If you want to upload images into the database from a client machine, you will need an extra step where you move the files to the appropriate directory or directories on the server. This example will store the images in a BLOB column, rather than a much more flexible interMedia ORDImage column. A BLOB column is fine if you only want to store and retrieve the image, but interMedia gives you significantly more flexibility to manipulate the image, extract metadata, etc.
Create the directory
First, you will want to tell Oracle where it can find the images you want to insert into the database. The easiest way to do this is to create a directory object. In this case, I will be loading images from 'c:\temp\img\'.
CREATE DIRECTORY images AS 'c:\temp\img\'
If you don't have the CREATE DIRECTORY privilege, you will need to have someone else, like your DBA, create the directory and grant you READ access to it.
GRANT READ ON DIRECTORY images TO scott;
Create the Table to Hold the Images
CREATE TABLE images (
image_name VARCHAR2( 100 ),
mime_type VARCHAR2( 100 ),
content BLOB
Create a Stored Procedure to Load the Image
CREATE OR REPLACE PROCEDURE load_image( file_name VARCHAR2 )
AS
file_lob BFILE;
binary_lob BLOB;
mime_type images.mime_type%type;
extension_pos NUMBER;
BEGIN
-- Use the extension of the file name to determing the MIME-type
-- The MIME-type for a .JPG file will be image/jpg
extension_pos := INSTR( file_name, '.' );
mime_type := 'image/' || SUBSTR( file_name,
extension_pos + 1,
LENGTH( file_name ) );
-- Insert a new row into the images table. Get the LOB locator
-- for the newly inserted row-- we will be using that to insert
-- the content from the file.
INSERT INTO IMAGES( image_name, mime_type, content )
VALUES( file_name, mime_type, empty_blob() )
RETURNING content INTO binary_lob;
-- Open up the file in the IMAGES directory named file_name,
-- load that file into the newly created LOB locator, and
-- close the file
file_lob := BFILENAME( 'IMAGES', file_name );
dbms_lob.fileOpen ( file_lob, dbms_lob.file_readOnly );
dbms_lob.loadFromFile( binary_lob,
file_lob,
dbms_lob.getLength( file_lob ) );
dbms_lob.fileClose ( file_lob );
END;
Load the Image

How can i store a variable to a file?

for some reason i can't find much on writing to files, is
this not possible?
and if it isnt possible, how can i keep a variable? i don't
want the variable to reset to 0 every time someone loads a new
instance of the page.
also, for some reason.. it seems to me that if statements
dont work as they should. the vote() function always executes the
countVote() function even if choice doesn't = ans.
anyone know what im doing wrong
example..
private function vote(choice):void {
text1.text=choice
if (choice=ans){
countVote();
private function countVote():void {
total=total+1
totalS=total.toString();
text2.text=totalS
text2 displays the total count and every time i submit the
vote, the count goes up no matter what i choose
i also get a warning for all of the variables saying
"1084: var 'total' will be scoped to the default namespace:
sv1: internal. It will not be visible outside of this package."
(sv1 is the name of the project)
how to i make it visible outside of the package?

In this case, the if statement will not work as you intended.
You need to use the double-equals, ie, if (choice == ans)
Also, the flash player is inside a sandbox for security
reasons. Consequently, you can not write directly to files. To get
around this, make a call to a php, python, java or .net script
residing on the webserver that will write to a file for you. You
can do this using the HTTPService object.

How can I store and view a pdf file ?

I have an iphone 3GS 32Gb and want to store a pdf file on my phone so that I can view it later.
Email is the only way I have been able to view my pdf file, but I dont really want to do it this way.
On previous phones I could save a file on the phones memory card and then open the file in the necessary app.
This is something I know the iphone doesnt do, but I was wondering if there is a way around it or an app.

[File Magnet|http://itunes.apple.com/gb/app/filemagnet-read-and-e-mail-your/id2847971 61?mt=8] is pretty good.
I did find one app (I cant remember the name, thought it was Air Share) and it said Apple had told them to change the app so that you cant transfer files over USB, only Wi-Fi.
I think that was [FileApp|http://itunes.apple.com/gb/app/fileapp-previously-fileaid-document/id2 97804694?mt=8], (previously File Aid).
Apple dont like people being able to use their phone like this.... bloody control freaks.
You can vote with your feet remember.

How can I make different catalogs from the same image

How can I make different catalogs from the same image where that image has been changed in some way between the catalogs. For instance if I wanted to have a catalogs for cropped images and have 3 catalogs one for 4x6 , 5x7 and 8x10 cropping. When I tried this , if I changed a file in one catalog that same image in the other would change also.

Do not confuse the creation of the crops and the display in collections per crop ratio.
Of course one virtual copy (VC) per crop ratio is needed. If the same image should be cropped in all 3 mentioned ratios there would be 3 VCs.
The OP asked how to have/see a set of same-crop-ratios.
After having created the virtual copies for whatever crop ratio he wants, the way to display this result in the fashion asked for is via smart collections, provided they can be found. Without a plugin the naming of the VC with the crop ratio applied is a straight way to achieve that.
IF the wish is to get new crops automatically added. (See my answers 2+3)
IF the wish is to creat static collections per crop ratio for a certain set of images, I'd go as follows:
1. Select all images you want to have cropped in that way,.
2. With this selection click on the + to add another collection and fill the dialog box like this:
Then navigate into this newly created selection and perform the 4x6 crop - according to taste individually or by synchronizing the first crop.

I signed up for my apple account while living in Canada, and now I lives in the US. I am looking for a specific app that apparently is only available through the US app store. How can I change my account to the US Apple Store?

As long as you have a form of payment (credit or debit card) with a USA source, and with a billing address in the USA, then you just need to change your payment information on your account to that, change your country in the store settings, and you will then be able to shop in the USA store.
Your AppleID will work in any country's store, as long as your payment source and billing addres are also specific to that country (and you are in that country as well, as there may be IP filters in place to stop use outside of the country).

How can I use applet to get the desktop image of client

hi,I have a question to ask u.
How can I use applet to get the desktop image of client? Now I develop a web application and want user in the client to get his current image of the screen.And then save as a picture of jpeg format ,then upload it to the server?
I have done an application to get the screen image and do upload file to server in a servlet with the http protocal.

Since the desktop image is on the client's local hard drive, you'll need to look at trusted applets first.

When I try to same an image under the command 'save as' it will only let me save as file types 'firefox document' or 'all files' and when I try to look at them later they dont work. How can I save an image as the same file type it is on the web site?!

== This happened ==
Every time Firefox opened
== I updated to one of the firefox versions (Not sure which one it was)

Thanks Alex, but sadly I already tried that. Neither .docx or .xlsx files show up in the content list. They both show as a Chrome HTML document so changing how Firefox addresses those doesn't help since it thinks its the same type of file. I don't think I can manually add files into the "Content Type" left side nav.

How can I attach an image without the image is in the email body? (using the new mail the Lion)

How can I attach an image without the image is in the email body? (using the new mail the Lion)
I want in attachment, not in the body mail.

I think your only solution is to zip the image files first and then attach them.
Read this from a site I found:
Sending Graphical Attachments -- When you attach a graphical image to your message, the recipient of your message sees the image inline (that is, in the body of the message) if her email client supports inline display. ("Take Control of Email with Apple Mail" contains a table listing the capabilities of popular Mac and PC email clients.) If a client does not support inline display (or the recipient has turned off the inline display option), the file appears as an attachment that must be opened in a separate program.
On the one hand, an inline image is easier for the recipient to see - all she has to do is look at it. On the other hand, inline images can be frustrating to scroll through. If you do not wish to send a graphical image inline, you must compress the file before attaching it - Mail, sadly, lacks a built-in compression option, though fortunately for Panther users, the Finder offers Zip compression without requiring a separate application.
Note that when you compose a new message, Mail always shows attachments in the body of your message. You can manually drag them somewhere else, but many email clients display all attachments in a separate list, regardless of where you place them in the message body.
If you paste an image into a message or drag & drop an image from another window (say, a Web browser), Mail converts the raw image data to an attachment in TIFF format. On the other hand, if you drag & drop the icon of an image file (or use the Attach button to locate the file using the file browser), Mail leaves the attached image in its original format. This difference is significant, because although most email clients can display JPEG images just fine, support for TIFF - especially in non-Mac email clients - is less common. If possible, I suggest attaching image files as opposed to pasting or dragging in raw image data.

HT201272 Having a bad day my iTunes library got corrupted and my back up disk has failed how can I restore my purchases from the iTunes store

Having a bad day my iTunes library got corrupted and my back up disk has failed how can I restore my purchases from the iTunes store? When I try it tells me the pruchases have already been downloaded to this computer.

Does your purchased rmusic appears under the Purchased link under Quicklinks on the right-hand side of the iTunes store home page (music can't be re-downloaded in all countries) ? If they do and you don't have the cloud symbol against them so as to re-download them, then do you still have the entries for them in your library i.e. where you would normally click on them to play them ? If you do then try deleting them from there (iTunes will be seeing them and assuming that you still have them somewhere) and they should then get the cloud symbol for re-downloading in the Purchased link.
If you aren't in a country where music can be re-downloaded then you could try contacting iTunes support and see if they will grant you a re-download : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page,

I am using an Macbook pro in conjunction with a Time Capsule. I back up all my aperture librarys on it, but how can i view these images that are stored on the capsule please ??

If you want to see what is in a file that is backed up by time machine then you have to restore the entire file. Having said that I have had good experience with Time Machine and individual files... if the file is there then all of it's components are almost for sure there. A way to get around this in Aperture would be to use referenced images. The images then still exist as individual files and can be backed up and restored individually. You would have to do so on a file by file basis though and your album information would still only be saved within the Aperture library.
