[flexcoders] Re: Cache-Control header not working in HTTPService

[dario.drome]

The http headers to control (and avoid the cache) come from the 
server side, that is, it is not useful at all that you set the 
headers from the client side.
In order to avoid cache you need to set the header "Pragma" with the 
value "no-cache" and also set "Expires" with "-1" to give your 
content an inmediate expiration, but remember: set these values from 
the server, not from the client.

Regards.

[flexcoders] Re: How to get the target node in dragEnter()

[dario.drome]

Tracy,
Possibly, if you implement dragEnter in a tree item renderer, then you 
can get the data's reference that you are looking for.

Let me know if you have success.

Hi Derrick,

FDS handles that issue very well (I'm not sure if you are willing to 
use Flex Data Services.)
Also you will find a very illustrative set of articles from Matt

See if this helps

[flexcoders] ByteArray.readMultiByte bug on Macintosh?

[dario.drome]

Hi,
I have isolated a problem that appears only when a SWF (built using 
Flex 2.0.1) runs under Macintosh:

The flex application reads a binary data package (serialized on a 
windows server) using an URLLoader
In that binary stream the server serialize things like numbers, 
single bytes and strings.
All is OK with the de-serialization of the data except with strings. 
They are serialized in a very simple way: first a byte containing the 
string's length and, then, the characters stream encoded 
using "Windows-1252".
When the application tries to de-serialize such a string, it first 
read the string's length (ByteArray.readByte) and then, it tries to 
read the "string body" using ByteArray.readMultiByte() method.
The result: when the client is a windows box (using firefox or MSIE) 
there is not any problem. However, when the client is a Mac box (OSX 
10.4 with FireFox) readMultiByte gives a different result each time 
it de-serialize the (same) binary stream.

The function where the problem is isolated is the following:

public function readString(binData:ByteArray):String
{
   var str:String="";
   var length:int = binData.readUnsignedByte();
   str = binData.readMultiByte(length, "Windows-1252");
   return str;
}

I think that I could get rid of the problem by reading each single 
string's character and applying my self the conversion from Windows-
1252 to UTF-8, but I would like to rely on ByteArray.readMultiByte.

Have anybody out there found also this problem?
Perhaps it is not a problem and I am doing something in the wrong 
way, Could anybody help?

Thanks in advance.

[flexcoders] Re: Convert ByteArray to Bitmap

[dario.drome]

I agree with Franto friend: You need to know something about the 
bytearray you are receiving, i.e. format, disposition, etc.
Most of image formats have a kind of header where you could find its 
width, height and so on.
Once you know the dimensions and the format, you would need to use 
the apropriate decoder to transform the bytearray in pixels of a Flex 
Bitmapdata object.

[flexcoders] Application's creationPolicy

[dario.drome]

Hi guys,
As far as I understand, the Application is a container and containers
have a "creationPolicy" that affect to the moment where container's
chidren are instantiated. Moreover, there are many examples showing
how to "createChildrenFromDescriptor".

The problem comes when one (me) need to defer the creation of
application's children until a more apropriate moment: if I set the
application's "creationPolicy" to none, then, "initialize" nor
"creationComplete" events are never fired (?)

The fact is that I would need to be sure that all my external styles
(CSS compiled) are properly loaded before any application´s children
start to instantiate or initilize.

I have succeded by inserting an instrumental container between the
application and its chidren but I'am wondering if it is really needed.

Any ideas.

[dario.drome]

It is not possible. You will need to perform that kind of selection 
by yourself (i.e. transversing the xml tree)

[flexcoders] Drawing a custom component in "offscreen"

[dario.drome]

Hello,
I would like to know if it is possible to draw a component in a Bitmap.
I have a custom component that graphically render some data tha user 
has input. I do no want to display it on screen but I would need to 
convert it to bimap data and send it to the server for storing.

I am able to do that if I first display the component on screen and 
then draw it in a BitmapData.

Any ideas?

Thank you in advance.

[flexcoders] Customizing the index.template.html wrapper

[dario.drome]

Hello Flexcoders,
I'm trying to figure out if there is a way to change the usual 
behaviour of the flex builder's generated html wrapper:

I want that the final html hosting my swf is an html generated by an 
aspx page on the server. Thus, I would like to configure FlexBuilder in 
such a way that it uses my own, let's say, "index.template.aspx" to 
have "myFlexApp.aspx" and "myFlexApp-Debug.aspx" generated at output.

If I replace the standard "index.template.html" with 
an "index.template.aspx", I get only one "index.aspx" at output which 
is the debug version (I think that FlexBuilder generates the release 
version first and then, it overwrites it with the debug version)

Is there any way possibility to do this?

Thank you in advance.
