Flex :: Can Do Binary File Input And Out
Mar 14, 2011I want to write a logging system to log errors but I want the format of the file to be binary. Can you write and/or read binary files in Flex 4? (actionscript to be more precise)

Java :: Binary Socket And Policy File In Flex
May 17, 2010I'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.
ActionScript 2.0 :: Load Binary File (a BMP File)
Feb 23, 2010it seems AS2/Flash 7 can't read BMP files. so I figure I'll write my own code to display a BMP file, like was doen here: (though it's AS3) [URL] just fine and dandy. but now I have to be able to load a BMP into memory first. AS3 can do this via FileStream or URLLoader, but what about AS2? * LoadVars attempts to parse the data it reads (ARGH!) so that's no good. * GetUrl could work if it could throw the data into a variable instead of a browser window, but that doesn't seem possible either.

Flash :: Source Control System For Binary File?
Oct 20, 2010We use subversion, which works great for software projects. We also have a lot of flash projects, which we don't use any kind of source control. Each flash project contain quite a few images. The time frame of each project is a couple weeks, but few can go upto a couple months.
The number of files we create contribute to quite a bit of file size. To keep repository size at a minimum, we want to keep the latest version only and wipe out previous history once a project is finished. History is useless to us after a project is finished.
It looked into subversion, but it doesn't allow to remove anything from the repository. I need to perform this workaround here.
One easy way is creating a separate repository for each project. When the project is over, save the latest version to archive and wipe out the repository. The number of active projects is about 50 - 100. Is there any issue with creating one repository per project?
ActionScript 3.0 :: Binary Socket Policy File On Server
Jan 15, 2009I 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.
ActionScript 3.0 :: Parsing A Text File Full Of Binary Data?
Jun 22, 2009i have a large text file full of several chunks of binary data, each chunk separated by "---"
so it looks like this:
[Code]...
I have loaded the data in an untyped variable. var data:* = URLLoader(event.target).data; so data contains all the text file content. my problem is that i want to parse this text file and put each chunk of binary data into a ByteArray.
any ideas of how i can go about doing that? i have never dealt with untyped variables before so i am not sure what to do. and i don't want to lose the binary data representation by casting (if that happens).

View 1 RepliesActionscript 3 :: Object Initialization Occur When Deserializing Binary Objects In Flex?
Sep 3, 2009The jist of what I'd like to know and focus on understanding, is details on how binary deserialization occurs in Flex 3. When is the constructor called, when are properties set, are private members serialized or does all deserialization occur on and through setters, etc? I'm having a hard time finding information on this.In a Flex 3 AIR application, I have a pretty complex object graph(just a bunch of objects referencing one another, kinda like a big data model except a bit more complex) that I serialize to a file using a single call on the FileStream.writeObject and readObject on a root object, which serializes and deserializes the entire object graph.I found that I needed to always have a default constructor, else I would get exceptions on the objects when deserializing if they were part of an ArrayCollection. So I had to eleminate the constructor parameters or set default values. I now have many setters like this in my classes, such as the below where mConnection accumulates some information it needs through different setters, where as before I had this all packed into the constructor since all of the information is really necesary for the Connection to function:[code]So the connection's serverIP is still an empty string because the server was assigned to the client's property before the server was completely initialized.
I could probably resolve this by using binding so that updates to the serverip in the server are bound to the connection, but I find binding properties to be fairly complicated (it's really simple on UI in mxml cause you just use the curly bracket syntax but doing it by code is what I found complicated). I have also resolved some cases by removing the constructor parameters entirely, so that there is no default values. All that aside, I still really need a deeper understanding of the details of binary serialization as far as how it rebuilds the object graph. I even have circular references, and it seems to handle those fine and maintain multiple references without duplicating objects. It's just when my constructors/setters are more complex that I'm running into these problems because of the order of what occurs during deserialization. It is really inconsistent though, as adding breakpoints in various places seems to influence the order that things occur, making it more difficult to debug.On a side note for anyone that might sidetrack the topic because I am serializing a class called Connection. I added some code to address some things, like in the Connection class there is an instance of a Socket. Of course my socket would not be connected after I close and reopen the application and deserialize it, so before I serialize my object graph, I go through and close the socket and set the reference in the Connection class to null, so that there is no longer a reference to the socket and thus it will not get serialized. After deserialization on the next application run I create a new socket.
