My Mysql database stores images (in PNG, JPG)of our personnel and it's field type is set to longblob.
Is there any possibility to load blob data type using HttpService and render it in Image component in Flex
I'm eager to know about as it comes in handy in the nearest future!!!
I've got 3 columns in an SQLite db I built with Firefox's handy SQLite Manager. So, I created 3 columns, an index/reference that's just an incrementing INTEGER for easy reference, a descriptive title of the image (so it can be searchable later) in a TEXT, and a BLOB type that holds the pngs.
I'm trying to add this in an assets folder into my project (as a pre-populated database) and display the blob images, one at a time, in a window one after the other, scrollable by user. This is where I'm running into problems. Eventually I want to be able to encrypt it and add a search tool, but first things first, and that's displaying an image.
I have spent several hours scouring the web about this topic, but there isn't much help out there: Adobe has tips about using SQLite with AS3 (their reference documents and the support section of their website have some overview articles) but nothing refers to reading blob data in depth.
On this site, I've found some references to Adobe Air looking for extra byte information when reading blobs since they have a different syntax to write to the databases created within the program. See: What is the first bytes in a Blob column SQlite Adobe AIR? Blob Sizeinfo?
var imageData:ByteArray = new ByteArray();
var headshotStatement:SQLStatement = new SQLStatement();
headshotStatement.sqlConnection = dbConnection;
[code].....
I'm using:
[Code]...
But I keep getting an "Error #2030: End of file was encountered." This is (probably) because the class I'm serializing is too big for the "String" object type in AS3. Is there a limitless object for storing an array of characters (or better yet binary), or am I going to have to make my own class? (like one with an array of strings)
I have a flex application which is hosted on Azure.
I have some data stored in a blob in a private container.
How can I use URLLoader to display the data? If I use a public container , then I am able to read from the blob in my application. However, if the type of the container is private URLLoader fails.
These are my errors: in Adobe Flash CS5.5
I don't understand why this script doesn't work. I am new to Action Script 3.0 and I watched this incomplete video on youtube. -- [URL] and I got the fails below.

I am building little games never anything too big. I'm having fun. I'm getting the following error message 1067: Implicit coercion of a value of type String to an unrelated type flash.display:DisplayObject.
It's got to do with the varObject variable I pass into the hitTestObject (at the end of the code) a. I exported the moveclip for actionscript and gave it an instance name so what's the problem???

So for instance, I've got three .as files called 'Helicopter.as, Game.as, Blue.as'
and I also have a .fla file called Helicopter.fla (These files are all suppose to link together, to make the helicopter game) . In the Game.as file, I have the following;
[Code]....
Flash doesn't recognise the original Helicopter symbol (in the Helicopter.fla file, because I deleted it). But I want the system to detect the 'circle' drawn using API (In the Helicopter.as file). And I have no idea how to how to name the API drawn circle 'Helicopter', thus I'm getting an error. So how do I name the API circle to 'Helicopter', so the Game.as file recognises it.
I need to be able to save and load images into an SQLite database using Flex 4.5 for a mobile application. The use case is this:
Inside the view there is a spark Image object with a URL as a source
When user clicks button, the Image is saved to an SQLite db inside a BLOB field.
In a separate Image, the source is set to the ByteArray stored in the db.
The biggest question so far is this: where do I get the ByteArray for a loaded Image? I've tried debugging and inspecting Image, BitmapImage, and BitMapData but there's no sign of the byte array.... perhaps it's inside the ContentLoader? But that's null unless I enable caching.
I've done some research and there are no complete examples for how to handle this. I've written a simple View that anyone can copy and paste into a new project. It will compile without errors and can be used for testing. I will update this code as I get the answers I need so that anyone can have a fully working example of this workflow.The only caveat: I used a synchronous connection to the DB to avoid complicating the code with event handlers, I wanted to keep it as simple as possible.I will only mark this question as answered once it is fully functioning both ways.
UPDATE SEPT. 09 2011: The code below is now fully functioning in both directions (save and load). Here are some of the things I've learned: It turns out that the ByteArray of a spark Image can be found inside the LoaderInfo of the image itself. Like this:
image.loaderInfo.bytes
However, trying to set this ByteArray as the source of another image ( image2.source = image1.loaderInfo.bytes) results in this security error: Error #3226: Cannot import a SWF file when LoaderContext.allowCodeImport is false.Which is too bad because it would save so much time and processing power.the workaround is to encode the ByteArray using either a JPEGEncoder or a PNGEncoder. I used the JPEGEncoder which produces much smaller files. Here's how:
var encoder:JPEGEncoder = new JPEGEncoder(75);
var imageByteArray:ByteArray = encoder.encode(imageToSave.bitmapData);
Now the problem is saving these bytes to the DB. Saving them as they are now will not work once we read them out, I'm not sure why. So the solution is to encode them into a base64 string like this:
var baseEncoder:Base64Encoder = new Base64Encoder();
baseEncoder.encodeBytes(imageByteArray);
var encodedBytes:String = baseEncoder.toString();
So now just save that string into the BLOB field and later read it out. However, you have to decode it from a base64 string to a ByteArray like this:
var encodedBytes:String = result.data[0].imagedata;
var baseDecoder:Base64Decoder = new Base64Decoder();
baseDecoder.decode(encodedBytes);
var byteArray:ByteArray = baseDecoder.toByteArray();
Now assign the bytearray as the source of your image and you're done. Simple right?if you find any optimizations or alternative ways to do this.I will respond and keep this code updated if need be.

Hi guys I get this coercion error: TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Shape@41754601 to flash.display.
When I create an instance of a MovieClip from my library:
var childmc:ChipEasy = new ChipEasy(); Canvas.Map.Tiles.addChild(childmc);
When I try to access all the children like: for (var i:int=0; i<Canvas.Map.Tiles.numChildren-1; i++){
var mc:MovieClip = Canvas.Map.Tiles.getChildAt(i);
}

Just started playing with the new AIR functions NetworkInfo and NetworkInterface, but can't build ...
This is the example I started from: tourdeflex But these lines cause errors:

var networkInterfaces:Vector.<NetworkInterface> = networkInfo.findInterfaces();
today i wrote my first "if" "else" conditional statement and it worked,I have a movieclip nested four levels deep inside other movieclips.It consists of some basic buttons and some artwork indicating what page your on. But i dont want this (i'll call it "navMovieClip")to be visible at all times because its an eye sore. I only want this movieclip to be visible when the mouse moves. Once the mouse moves, the movieclip will fade in, once the mouse stops moving, the movieclip will fade out, UNLESS they stop with the mouse OVER the "navMovieClip".

The save method looks to be working:

$ba = new Zend_Amf_Value_ByteArray ( $im->bArray );
$data = mysql_real_escape_string ( $ba->getData () );

I am trying to access a .Net service which requires an authentication header. If WebService is used it works fine. But when it is accessed using HTTPService it throws error. The project is already done by somebody else using HTTPService. Now changing to webService requires some time since there needs to be modification in a lot of files.
Below is the SOAP envelop required by the service.

It goes like this, we need to detect if the display is a Projector (or if the system is connected to a Projetor).the catch is this should be done from within the browser.so is it possible to do so by using anFlashActiveX (this does constrains to a single browser, so not an option)searching so far only reaveals display resolution. expecting if there is something still out there.
View 2 RepliesI have a logo that I made in Fireworks, and it looks decent, but I was wondering if anyone could mimic it with movement. For example, if someone could use actionscript to make it "wiggle" or wave like a flag in the wind, that would be awesome.
Notice how the blue line itself stays at about the same thickness (it barely starts getting thicker), but the shading around it thickens as it goes more and more to the right.
Here's the image (ignore the text):
I was browsing the net and came upon this site, which has a really cool blob-like borders effect. I really wanted to learn how to accomplish this effect, here's what I know as of now:
1. I must have an array of points, connect them using curveTo and fill it. For this I have to use this methods:
createMovieClip, lineStyle, beginFill, moveTo, curveTo, endFill
2. Then I must have a proximity detector for each point, more or less like:
dx = point._x - _xmouse;
dy = point._y - _ymouse;
distance = Math.sqrt(dx*dx + dy*dy);
And if the mouse is too close to the point make it move away with a certain velocity (but only if the mouse is moving, if it is still, just make the blob wobble for a while, using an elasticity effect).
point._vx += point._ax;
point._x += point._vx;
Where the acceleration must be a fraction of the distance we calculated before:
k = .2; // example
point._ax = distance * k;
But we must also have damping so we can have the elastic movement, so:
damp = .9; // example
point._vx += point._ax;
point._vx *= damp;
point._x += point._vx;
3. Finally when the mouse is clicked on a blob we must communicate with the others and make them all wobble, by using LocalConnection. How do I make the array with all the points and access them?; how do I impose the proximity detector into each point and make the curveTo's change?
