I have a custom socket class designed to connect to a server and talk with it. At one point, the server uses hex data for speed, however Flash seems to not get ANY of this data. In fact, it doesn't get ANY of the data from that point to the next packet.

I'm using a binary socket to talk to a server and it works fine the first time I send data. Then I receive data from the server and send a response but it's never received... like the connection closed or something. I have an event handler on the socket close event, but it doesn't fire. I can trace to the socket sending data, but if I trap the data received event on the server, nothing is received.. like it's closed the socket. Is there something I need to reset or have I missed a key concept in binary sockets?

View 1 RepliesI'm trying to make a little ftp upload app - not a full FTP client, just something to enable image upload with decent performance. I basically took the approach Lee used in his POP3 socket tutorial. The problem I'm having is that I can connect to the FTP server and I can authenticate and log in but as soon as I try to enter passive mode for data transfer I get nothing- not even an error. From looking at the FTP RFCs, FTP requires two TCP connections - a command connection and a data connection - does this mean that I need to open a second socket for the data transfer? Another possible issue is the Flash Player security policy not allowing conection to ports under 1024 - I have not placed a policy file or policy server on the host running the FTP server but as I can successfully login, I appear to be able to connect to port 21 (standard FTP port) anyway. The code I'm using is:
Code: Select allvar s:Socket = new Socket("ftp.actechnology.co.uk",21);
var ftp_response:String;
s.addEventListener(ProgressEvent.SOCKET_DATA, receiveReply);
s.addEventListener(IOErrorEvent.IO_ERROR, showError);
[Code].....
why passive mode kills it or has successfully connected to a FTP server with the socket class
I'm trying to evaluate whether Flex can access binary sockets. Seems that there's a class calles Socket (flex.net package). The requirement is that Flex will connect to a server serving binary data. It will then subscribe to data and receive the feed which it will interpret and display as a chart. I've never worked with Flex, my experience lies with Java, so everything is new to me. So I'm trying to quickly set something simple up. The Java server expects the following:
DataInputStream in = .....
byte cmd = in.readByte();
int size = in.readByte();
byte[] buf = new byte[size];
in.readFully(buf);
[Code] .....
After that - EOFException happens on the server and that's it. So the question is, am I approaching whole streaming data issue wrong when it comes to Flex? Am I sending the policy file wrong? Unfortunately, I can't seem to find a good solid example of how to do it. It seems to me that Flex can do binary Client-Server application, but I personally lack some basic knowledge when doing it. I'm using Flex 3.5 in IntelliJ IDEA IDE.
I am attempting to setup a binary socket connection between flash running on my desktop and a Rabbit RCM3800 Microcontroller providing the server on my home network, which has no file system and has a very basic http server on it. Due to limitations of the microC I cannot run Java/Perl/Python or any other server on it other than setting up a server using its own native Dynamic C language (essentially manually opening and controlling sockets in C). I am able to successfully connect to a socket on port 3333 of the server and transfer information between the server and the .swf file when it is the sandbox type "local-trusted" (while I'm debugging in Flash).
Because of this I'm fairly certain the code to setup the socket between the server and flash works fine. My problem occurs when I try to run the .swf file as "local-with-network" (such as running it after publishing on my desktop) or "remote" (accessing the .swf file when it is located on the server) and it then requires a socket policy server to host a socket policy file on the server. On my server I have code setup such that whenever a socket opens on port 843 or port 3333 (my data port) and sends a stream of raw data containing the request <policy-file-request/>, the server writes back in ASCII the below code and closes the socket.
Code:
Select all<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "[URL]">
<cross-domain-policy>
<site-control permitted-cross-domain-policies="all"/>
<allow-access-from domain="*" to-ports="*" />
</cross-domain-policy>
[Code] .....
So for some reason flash times out while waiting for the socket policy file. I have tested sending the <policy-request-file/> over telnet, and have received the above policy file. I have also sniffed using wireshark and saw that my desktop sent the policy request and received the policy file. I am guessing that Flash times out because it is waiting for some kind of terminating character that states the end of the policy file, and to that end I have tried sending. Interestingly, instead of sending the policy file I have tried sending random data from the server to flash, and flash displayed the Warning: Ignoring policy file at (URL) due to incorrect syntax. Because I don't receive this warning when I send my policy file I don't think it is formatted incorrectly.
I have also tried using the below flash code to hold the socket request open indefinitely, but it also errors after 20seconds.
Code: Select allSecurity.loadPolicyFile("xmlsocket://192.168.1.59:843");
The .swf file will eventually reside on the server itself at 192.168.1.59/myProg.html. I have only tested the flash file remotely on the server a couple times, and in addition to the previous warnings/errors, I received the warning: SWF from (URL) may not connect to a socket in its own domain without a policy file.
I am starting with a short introduction: I am currently working on a project, which involves a server application written in .NET (C#) and a flash gui app as client (standalone flash player 10 [code is written in Actionscript 3.0]). The server constantly sends bitmaps to the client (up to 30fps). The connection is established using binary sockets and data ist streamed to avoid socket open/close/reconnection problems.The bitmaps sent to the client are marked with begin- and end-tags. A length field was added as well, to optimise the following parsing process. The client buffers the received data up to the point where an end-tag is found. The client reassambles the bitmaps on the screen by parsing the current buffer. Parsing means looking for begin-tags and length fields and/or end-tags of pictures packages. The resulting bitmap data is copied into a byte array and will loaded into a movieclip using the flash.display.Loader class ( bytePictureLoader. loadBytes( byteArray ); ).[code]While testing, I found out that in some cases the data stream becomes currupted, i.e. data is lost and/or the transmittion is incomplete.
A good thing is that this error is reproducable.It seems that as soon as the Flash Application Window is dragged (moved on Windows Desktop) the stream lacks data. The same error occurs, if too much data is sent to the client. The results are performance problems, data loss and other strange effects. The more data is sent on the stream, the more data has to be parsed and the more data gets lost somehow. Sometimes this leads to a memory problem, because Begin- and End-Tags aren't transmitted correctly. In order to fix (counteract) that, I discard data as long as there is no Begin-tag found and the buffer is cleared when the size exceeds 1Mb.It works so far, but the application lacks performance and stability.I.e. If 20 bitmaps per second with 620x390px are sent to the client, the client only receives 16 to 17 bitmaps, if the application does nothing else.If 30 bitmaps per second with 620x390px are sent to the client, the client only receives about 20 to 21 bitmaps.I am guessing that using actuall video streams would be better, then sending one bitmap at a time in a byte stream.Is there a proper example on how to build a client app in flash to receive/parse a binary data stream?Does anyone else has recognized the lost-data problem or the interruption of streams?

We have a system that allows a user to upload any image, which we store on the server. Of course, it is simple to load an image (that you know the path to) using loadMovie, but I also want to load certain pieces of meta data about the image that is precalculated and stored on the server; we may one day want to retrieve things completely unrelated to the image as well, so consider the non-image data to be arbitrary.So, that said, is there a way to simply return the image as a variable (urlencoded and returned in a loadVars request, perhaps) and then load that data into a movie clip?
Bonus Lightning Round Question: Is there a way to check the output of a PHP script which processes uploads when the request is sent via FileReference.upload(url:String)? Should I load/escape the binary data and then send it using a loadVars() request if I want to see the output?

View 1 RepliesSometimes flash-socket ignors data which is being sent by server. I dunna know exactly if it's server-side problem(data actually aint being sent) or flash.How does flash handle numerous of data packages comming from server ? I know that flash perform all actions in single thread, but what happen when flash recive a lot of packages at same time ? Does flash serialize incomming packages and then call ProgressEvent.SOCKET_DATA for each package or just ignore those packages which cant be handled runtime ?

unpacking data from a binary string. I realized it with a php code:
list($empty,$size) = unpack( 'V', fread($socket,4) ); $theresult = fread($socket,$size);

I've got XML data in AS3 that needs to be compressed, validated on my Java Google App Engine servlet then saved to a file in Google Cloud Storage.

View 2 RepliesI need up upload urlencoded binary data to tumblr.this is what I'm currently trying:
baseString.params = 'data[0]=' + URLEncoding.encode(byte.toString()).replace('~','%257E');
1 - SWF must have ability to loading binary data from any domain.
2 - SWF cant load policy XML file from url, cause upload form allows me only to upload swf files, so I cant include any other data.
I tried:
Security.allowDomain("*");
But it works only for SWF files.I tried to embed policy XML file:
var dataXML:XML =
<?xml version="1.0"?>
<!-- http://www.foo.com/crossdomain.xml -->
<cross-domain-policy>

This will make an security error, if file is from different domain than SWF file.Its possible to get binary data from JavaScript using ExternatInterface in AS3 code.Here is cross-browser library for reading files binary: binary reader and later version jDataView.
