ActionScript 3.0 :: ByteArray To Cffile Binary File?
Mar 17, 2010
I m trying to write AS3 to take a screenshot of a MC thats on the stage and pass the data to a .cfc method which saves it as a jpg on the server.The current code I have kind of works except the jpg is unreadable.I think it has something to do with not using Flex, AMF, and writing binary files.When I look at the jpg via a hex viewer I think it doesnt have the right jpg header.The jpg begins with:c3 bf c3 98 c3 bf c3 a0 00 10 4a 46. When I think it should begin with:ff d8 ff e0 00 10 4a 46
I have an array of objects. Each object has 3 integer fields and 2 binary fields.I've utf encoded the binary data and json encoded the array & sent it to Flex client side.On the client side, decoding data, I've got a String representing the binary data (utf decoded).Now, how can I convert this String to ByteArray? Or how can I read each byte of the String?
I've been asked to implement and MD5 hasher ActionScript-3 and as I was in the middle of debugging how I formatted my input I came across a problem. When I try and output the ByteArray as a binary string using .toString(2), the toString(2) method will perform some short cuts that alter how the binary should look. For Example
var bytes:ByteArray = new ByteArray(); bytes.endian = Endian.LITTLE_ENDIAN; bytes.writeUTFBytes("a"); bytes.writeByte(0x0); var t1:String = bytes[0].toString(2); // is 1100001 when it should be 01100001 var t2:String = bytes[1].toString(2); // is 0 when it should be 00000000
so I guess my question is, might there a way to output a binary String from a ByteArray that will always shows each byte as a 8 bit block?
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
I 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.
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 have some binary data and I can't store it in a string, as such I'm using a ByteArray. The problem is that I need some functionality that comes with strings, to be specific I need the charAt, substr, indexOf and substring methods.
How to encode LONG_INT binary representation from AS3 Number data type (using ByteArray)?Need it for implementing data transmission protocol between client and server.
it 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.
I 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)
But this did not give me the binary content of the file.. how to retrieve the full binary content of the given file using Flex (I am using FP 10.0).....
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.
We 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?
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.
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 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).
I need to create some sort of video-editor for dummies, which has to generate a video file as output.The editor has to load a movie-file scale and rotate it to a certain degree, and generate a composite video of a background bitmap and the rotated and placed video.The frontend will be done in Flash/AS3 and has to use some background tools for processing the video.Can I use FFmpeg to generate such a composite? Or is there any other good background task available?
I am working on a game, made with Flash (using AS3) The game has a fast ball and when this ball hits an object it has to make a sound... but the sound starts with delay (so the ball is far away when the sound is played).This sound is edited by me and it hasn't got any silences at the beginning.The method i'm currently using is the simplest one:
public var sonidoPuntos1:sonidopunto1 = new sonidopunto1()
and then...
sonidoPuntos1.play()
I am trying to introduce the file into a ByteArray and then playing it from there...
Well, i am recording the voice from heaphone and the sound data is stored in ByteArray at runtime, now can i stored as mp3 ?i want to save as mp3 file on the client system.. For that, i think i have to use air application..
There is a WSDL which have one method which take byteArray & fileName(which i want to write) as a parameter to write a file in local system, the following is the code...
public void writeLocation(byte[] byteToWrite, String fileName) throws FileNotFoundException { StringBuffer fileLocation = new StringBuffer("D:\Products\Device");
[Code]....
but the flex 2 showing the error when i searched i found out in flex 2 there is no "data" property. so i am unable to create the selected object into byteArray..
how to convert a file I have on my server (pdf/excel/ppt) to a ByteArray. The reason I want to do this is to display the dialogue open/save as to the user and I must set the Content-Type to octet-stream. The dialogue shows fine with just navigateToURL() but for pdf's it is the user's local browser setting. For a URLRequest I must set the data as a ByteArray. I'm trying to use the code located here:
I think I have a basic understanding of using bytearray and saving data to a local fileI've been able to save the data (strings) and bring them back.To start off, I have been teaching myself AS3. I have no knowledge of PHP or where to start with that. It has been said many times that you cannot make a txt file from within flash. Unfortunately this is what I need to do.I put together a map labelling app to use at work here. (it loads in a floor plan, then you can add 'nodes' that track info on each office - employee, ext, office #, data line jack, etc.) I would like to use this data in an access database that I have already running.in short, I would like to output my data from the mapper to CSV. On putting the data into a bytearray I am comfortable with marking the commas as well as line ends, but the data is not txt... is there a way to convert it
How do i open file and get its content as a ByteArray in AS3. I saw examples, using FileStream & File classes from flex.filesystem, but the doc says it's for AIR only.
I need to write a ByteArray to a file on local disk with Flash AS3. The flashapplication is run locally (it's a projector exe).
I found the FileReference class with the save() function which works perfect. The only problem is, that this function opens a filebrowser and let's the user select where to store the file. However - i have the path already as string and need to save to this location without useraction (since i'm exporting a lot of files into this directory in one go and don't want the user to choose each one manually).
Is there a way to store a bytearray from a projector to local disk without opening a filebrowser?
I'm also using mdm Zinc, which actually provides a function to save a ByteArray to disk, but this function is for some unknown reasons not working. I already filed a bugreport, but I need to get this to work very urgently, so i'm looking for alternatives!
I have an Air application with remote service in codeigniter.I'm trying to save a bytearray that I received from the Air app but when I save the data I get empty files with the correct filename.So there must be something wrong with my bytearray or the way I save the data.Does anyone have an idea what I'm doing wrong?I've debugged the Arraycollection I sent and the bytearray is definitely in there.
public function uploadImage($image) { foreach($image as $img)
I am using the FileReference object. I want to be able to save the local file data into a ByteArray. I know that I can use the data property in Flash 10, but I would like a solution that works for earlier versions of Flash.
I am trying to take data that I have extracted from a ZIP file in Actionscript, then convert it to a File object so I can write it to the documents folder for my air app to use.
I want to open a pdf/excel/doc using flex, as all know we can use navigateToUrl(URL) method to open a file from the server. But my problem is those files are encrypted in the server, so I load the files as follows
ByteLoader = new URLLoader(); ByteLoader.dataFormat = URLLoaderDataFormat.BINARY; ByteLoader.load(new URLRequest (constructedURL));
so that I can manipulate them and can get the decrypted file. Now my question is, my data already got downloaded from the server, so how will I launch the files(pdf/doc/excel) with the binary content which I had got?
Is there anyway i can launch those files like we do it in navigateToURL()?
