Socket data progress on "write"

Hi,
I have a problem with the Socket determining how much data is already written/sent through a socket connection on Flex (not AIR).
What I am doing is: first loading an image using the FileReference.load() function and later sending the byteArray to a RESTful server backend using HTTP_PUT. Its working fine that way, but I am now missing a way to figure out how far the "upload" is going.
The Socket is done as followed:
request.writeUTFBytes(header); // header is String
request.writeBytes(data, 0, data.length); // data is the image-ByteArray
socket.writeBytes(request);
socket.flush();
On socket.flush() the data is written to the outputStream, but I don't have a clue to see how much bytes are already written.
I know I could use the FileReference.upload() function which provides a ProgressEvent, but I can't do the upload via HTTP_POST.
Does anyone have a clue how to get a progress on a socket write?
- Daniel

Yes, this will install entire DataSocket software. This includes: DataSocket Server, Manager, and Help.

How do you set the number of rows in a spreadsheet, so that even when you drag data in, in writes over those rows instead of adding a new row?

How do you set the number of rows you want in a spreadsheet, so that even when you drag data in, in writes over those rows instead of adding a new row?

After the discovery reported above, I filed this report :
Bug ID# 10073038
Summary:
When Numbers is used on a system with decimal comma a csv file may be good AND wrong
Steps to Reproduce:
With Numbers v2, you introduced an interesting enhancement.
In system using the comma as decimal separator, Numbers requires csv files using the semi-colon as values delimiter.
In fact it’s true if we OPEN the document dragging its icon on Numbers one or thru the open dialog.
This said.
(1) Drag and drop a csv built with the 'semi-colon' standard on a table or on a sheet
(2) Drag and drop a csv built with the 'comma' standard on a table or on a sheet
Expected Results:
Every normally constituted user assume that in
case (1) he will get a perfectly built table
case (2) he will get every cells of a row in a single cell
Actual Results:
In fact you forgot the drag and drop way of use and in
case (1) every values separated by semi-colon are inserted in a single cell
case (2) values separated by comma are correctly spread in a table
isn’t it ridiculous ?
Regression:
Except looking in QuickView to see which is exactly the structure of the file to decide the way we will insert it in a Numbers document, we may use an applescript fair enough to replace the semi-colons by TAB characters
or
to replace the commas by TABs and the decimal periods by commas
Notes:
While I am on this subject, I wish to make two proposals:
(1) It would be fine to format the date according to the ISO format year-mm-dd when you export a Numbers doc to csv.
Doing that, dates would be imported correctly in every countries.
At this time, on an English system, you export as mm/dd/year.
If the doc is open on a system using the format dd/mm/year, the results will be odd.
On a system using the format dd/mm/year, you export this way and so, if the doc is open on a system using the format mm/dd/year the results are odd too.
As every localized versions accept the ISO format (at least on entry), using it in the export scheme would give a correct behavior everywhere.
(2) It would be fine to add the format Tab Separated Values in the Export pane.
TSV + ISO date format would give documents opening flawlessly everywhere.

Lost all contact info. All my Aps are there but all the data/progress is missing. When I plug my iphone into the usb fto synch up with my itunes on the computer a message comes up and says "enter the password to unlock your iphone backup file". This is very frustrating

I suggest trying the update again after an hour or two. Sometimes, the notice that an update is available comes an hour or two before the developers actually sends the revised app out to be downloaded.

How can you delete an app without losing saved data/progress?

How can you delete an app without losing saved data/progress? Is there a way through iCloud? I have an 8gb 4th gen iPod touch. I have a lot of music, so with 8gb, space is limited. Some apps I have take up 20-30 MB. Some of these games I don't play that much, but I don't delete them because I have made a lot of progress (levels, scores, acheivements). It would be nice to delete some of these 30 MB apps that take up precious space, and them redownload them in the future when I have more space, but without having to start the whole game over.
Also, I read somewhere that there might be a way to do this with iCloud, but I don't really know how.
Thanks!

This is the only way I know of. It is messy though.

Problem with App Game data/progress and restriction passcode

Hi,
Here is my problem, for an unknow reason my 7 yrs old daughter was able to add a passcode for the restriction including SAFARI. Naturally, she doesnt know which passcode she put TWICE!!
Since I want to be able to navigate on SAFARI the only way I found was to do a restore via iTunes.
THE PROBLEM is that by doing so I will be losing ALL my apps game data/progress which I dont want.
I have an IPAD 2 with the latest version 7.0.4.
What is the solution to reset the restriction password without doing a full restore or how to do a restore without loosing my game progress/Data?
Tx

That's just not right... Why isn't there any kind of a warning? This is ridiculous, since you can never be 100% sure you can finish the downloading. Your dog can pull out the router power cord, or anyting can happen during these let's say 10 seconds...
How about if I wait until a next update comes up, and I try to install it, would that solve the issue?

I lost my orange data progress bar, now its a dumb box with words describing every piece of data, what did I do?thanks

Hi, I did a bunch of supposed upgrading, and getting rid of non compatable add ons, etc. now I have lost my data progress bar, and there is a biggish annoying box, in the bottom left corner, describing every piece of data my computer is zooming through as it gets on a site, also my mouse gives a little preview box as I put it in a word or icon on a page, are these annoyances connected , I got rid of a perfectly good google toolbar ubantu said was not compat.perhaps it was what was giving me the icon data bar? I have tried everything, anyone have an idea? thanks alot, Lisa

Use Data Socket vi's to write to a custom namespace OPC server.

Hi there,
I'm still having the following problem:
I'm trying to write an OPC tag to my OPC server that is currently not
existing in the servers name space.
Normaly (with other OPC clients) the server fires an event that validates
and adds such unknown tags
to the server if they are not existing.
These event is fired through the labview client, too, but unfortunately the
parameter that tells the server what
data type the server should use to register the new OPC item is always zero
(uninitialized variant typ) instead
of VT_UI VT_DBL or any other value for a valid typ.
Does anybody know how to register unknown but type save OPC items to an OPC
server with LabVIEW 6.1 / 7
data soket vi's ???

Hello Bryan,
The BrowseDeviceList VI was released within NI-FBUS 3.2. For NI-FBUS Configurator 3.1, please unzip the attached file and copy the "addon" and "Ff" folders into "\vi.lib" directory. LabVIEW 7.1 or above version is required for using these addons.
And for your information, there is a free upgrade (version 3.1.1) for NI-FBUS Configurator 3.1 users. Here is the link to the upgrade kit.

Socket data corruption

I've a problem with sockets that I can reproduce with this simple code:
public class Server {
public static void main(String[] args) throws Exception {
ServerSocket server = new ServerSocket(8888);
System.out.println("Listening...");
Socket socket = server.accept();
InputStream in = socket.getInputStream();
byte[] data = new byte[16 * 1024];
while (true)
int i = in.read();
if (i != 202)
throw new Exception("Error: " + i);
else
System.out.println("Ok");
in.read(data, 0, 16 * 1024);
public class Client {
public static void main(String[] args) throws Exception {
System.out.println("Connecting...");
Socket socket = new Socket("localhost", 8888);
OutputStream out = socket.getOutputStream();
byte[] data = new byte[16 * 1024];
while (true)
out.write(202);
out.write(data, 0, 16 * 1024);
The "Client" class connects to the socket listening in "Server" class and send a byte and a 16k block in a loop. The "Server" receives the data and verifies the byte (It should be 202). At some point the test fails receiving a "0".
I'm using JRE version 1.4.2_04-b05 under Windows XP.
Any suggestions?
Thanks,
Juan Wajnerman

You can't predict what length a read will produce, it
may return any number of bytes up to the number
requested. You're right! Thanks... I don't know how I could forget that :-(
The writes also won't necessarily send
anything into the network if you don't do a flush.
Note that out.write(data, 0, 16 * 1024); will write
16K of whatever is in the buffer.Thank you very much!
Juan

File transfer using non-blocking sockets - data mysteriously vanish

Hello,
I need to pass some big amount of data using sockets. I my appliaction I have noticed that sometimes I didn't get all bytes. To check it out I wrote simple client + server to figure out what is happening. So:
- I have a sender and receiver application
- I'm trying to transfer 5MB text file.
- On receiver side, output file is never larget than 3MB
- If I put some timeout on sender side (1ms timeout between write operations) everything works fine.
Could someone tell me what I do wrong? Why data disappears and when? The same file transfered using old sockets goes always fine...
Thanks in advance!

There are at least two problems here.
A. In the receiver you should test for -1 from the read() immediately, rather than continue with the loop and try to write -1 bytes to the file.
B. In the sender you are ignoring the return value of client.write(), which can be anything from 0 to the buffer length. If you get 0 you should wait for another OP_WRITE to trigger; if you get a 'short write' you need to retry it until you've got nothing left to write from the current buffer, before you read any more data. This is where the data is vanishing.

Recieving Socket Data Question

How can i recieve a large amout of Data from a socket.getInputStream()??
I use DataInputStream as my Main Constructor...

One of the big problems with using Sockets is you have
to know a lot about the data you are receiving just to
get the commication to work.
One thing you might do is check to make sure the
server application is flush()'ing its output stream
when it writes to it.
If you know that your data will 4096 bytes, you can do
something like this:
ByteArrayInputStream in = new ByteArrayInputStream(
socket.getInputStream());hhhmmm.... i think there an error here... on constructing ByteArrayInputStream
ByteArrayInputStream(byte[] buf); it doesnt seems to recognise inputstream!!! need advice..
byte[] data = new byte[4096];
int bytesRead = in.read( data, 0, 4096 );

Socket data to sound

Hi all,
I am getting data from shoutcast server using socket object.
How I can pass the data to sound object so that i can play
Is there any way to play the data from the shoutcast.
Thanks in advance
Please help me.

Have you looked at the shipping examples? There's one called Continuous Sound Output that uses the Basic Function Generator to create a waveform and SO Write to output it on the sound card.
