I experience strange behavior of sockets in Python (3.2). Client connects to my application using Flash. Most of the time there is nothing unusual but sometimes python crashes in a way that should not have taken place - enter into infinite loops. Below I attach to the loop code and error message in the log. Python hang on bytesRecived = sock.recv(64) and receive b'' witch is visible in log.
code:
try:
buff = ''

I have created a flex application in the Python Gae sdk and I got the error 2048, so I put a crossdomain.xml under the static folder.
The crossdomain.xml is following:
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy> [code].....
However, I still got the error 2048. Therefore, I would like to know is anything I need to configure or miss in my case and how to fix the error.
Does Adobe Flash expose any Automation or hosting interfaces through COM or a DLL in %systemroot%system32? I'm working with Python and wxWidgets to host a flash application to monitor lunar phases.

i develop one project on python and upload on google app can i use swf file to import in python web application?
View 1 RepliesI 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.
View 2 RepliesI wrote an image editor for my cms and wanted to send the image respectively the through the BitmapData's getPixels()-method received ByteArray to a PHP-script that displays and finally saves the image. Obviously I didn't succeed. How do I have to encode my binary data so that PHP is able to read it and how do I have to treat the bytes in PHP? I also tried encoding the image data with the corelib classes from [URL] but it didn't work as well.

(ii) I cannot cast my binary data as a movieClip var item:Bitmap has to stay as a bitmap so either I make a copy of it as a moveclip and reflect it or find a way to pass it directly into the new Reflect() constructor.

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?
I'm trying to load some binary data from server like this
var urlRequest:URLRequest = new URLRequest("http://localhost/test.php");
var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, completeHandler);

I'm trying to retrieve binary data using AS3 from a PHP server via HTTP, but very often (~50%) a few bytes arrive corrupted.
PHP snippets:
header('Content-Type:binary/octet-stream;');
echo $this->page;

So, as the title says I was wondering if it is possible to scale bytearray/binary data from lets say 640x480 which is being captured from the stage to 1024 x 768
View 1 RepliesI am working on the web base flash application I am trying to communicate with server through binary socket to the server IP Address and Port using Action script 3.0 at the server side we are using java. I will like to send binary data string to the server in a clubbed single packet.
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 ?
View 5 RepliesI have a problem with my application. Here's what i have up till now[code]...
Everything works fine, you can scale the image etc.
I would like to download the new image after you scaled it. I have been trying it for a long time now but i cant get it to work.[code]...
I'm missing a couple of bits somewhere. I'm trying to send and receive compressed binary data using AS and PHP, but I receive allways the error "Error #2058: There was an error decompressing the data". [code]...
View 1 RepliesI would need to save some binary data (bitmap data or similar) as a part of XML file.[code]...
I suppose I must serialize or encode "ba" (binary bytearray data) some way to string before writeing to XML and decode them back during the reading from XML, but I cannot find the correct way how to do it.
How can I change this so it saves the image as binary data. This code works fine but when the image is created the file size is too big.
Code:
import flash.display.BitmapData;
import flash.geom.Rectangle;
import flash.geom.ColorTransform;

I am trying to make a flex application where it gets data from a telnet connection and I am running into a weird problem.To give a brief introduction, i want to read data from a process that exposes it through a socket. So if in the shell i type telnet localhost 8651i receive the xml and then the connection is closed (I get the following Connection closed by foreign host.)
Anyway i found a simple tutorial online for flex that essentially is a telnet client and one would expect it to work but everything follows Murphy's laws and nothing ever works.Now i have messages being printed in every event handler and all places that i can think off. When i connect to the socket nothing happens, no event handler is triggered even the connect or close handler and if i do the following the socket.connected returns false! I get no errors, try catch raises no exception. I am at a loss as to whats going wrong?
socket.connect(serverURL, portNumber);
msg(socket.connected.toString());
Is there something about telnet that i do not know and its causing this to not work. Whats more interesting is why none of the events get fired.The following is the python code that works!
def getStats(host, port):
sock = socket.socket()
sock.connect((host, port))[code]....
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);
But how can i do this in as3 ? I didn´t find a possibilty to encode "unsigned long (always 32 bit, little endian byte order)". Is there a option like unpack in as3 ?
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. Later that file will be opened and decompressed by the AS3 client. The process works if I do it with plain XML or text, but if I ByteArray#compress the data, it dies during ByteArray#uncompress with "There was an error decompressing the data".
I've tried setting the content type and mime type at various points, as well as encoding with Base64, but every attempt seems to break in a different way and I never get the same XML back that I sent in. Do I need to use multipart? Should I compress on the server? [code]...
im doing a level editor for my game and i need to save the tilemap data (120x120 uint array) and character data (character type, position, rotation, stats, etc) to a .bin file. How can i do it? I know i can do it by using XMLs but it is not good for saving tilemaps...
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>
[code]....
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.
i have a string which contains all binary data. the binary data represents a custom object in my application.
i want to convert all the data inside the string into binary format and store it in a ByteArray. then I want to read the object from the ByteArray using readObject.
I'm trying to write a flash program that will import JPEG's and embed them into an XML string for storage. However, i'm having some trouble with casting them back into Bitmap objects, after encoding and decoding the strings in Base64.
I've used the external Base64 encoding class created by Steve Webster, which seems to work great in encoding and decoding the files, but i'm clearly doing something wrong in my code. I'm not sure how exactly I should be converting the decoded bytecode back into an image object, and get flash to display it. Should it be a bitmapData? do I have to code it via setting the pixels manually? Or can I simply just cast it as a Bitmap object?
here's a snippet of my code to show what I mean - At the moment this will return an error. Other things i've tried seem to return the object as a memory reference, rather than it's actual data.
(trace statement)
decoded.readObject() = ����
Error: Error #2030: End of file was encountered.
