[flexcoders] help with Images loaded from MSSQL Server
Hello everyone.
I'm back with another question, but this time its about images.
I saved a bunch of image files(all jpeg,jpg) in the bank, there they
become binary. when i get them from the bank i change them into images
again and take them to flex. at least that's what it was suposed to
happen, but it doesen't seem to work. altough it does seem to be sending
something to the Flex App it doese'nt shows nothing to the user :(
here's a sample of my MXML:
public function PegaImg():void{
Grid_Amostra.selectedIndex = -1;
Grid_Amostra.dataProvider =
dadosGrid.lastResult.SelectItem;
ArrayTree.removeAll();
for each(var campo:Object in Grid_Amostra.dataProvider){
var u:URLRequest = new
URLRequest('pegaitem.asp?cd_img='+campo.Cd_Img);
Carrega.load(u);
ArrayTree.addItem({display:, Desc:campo.Desc,
Dt_validade:campo.Dt_validade, Cd_Item:campo.Cd_Item,
Cd_Img:campo.Cd_Img})
//ArrayTree.getItemAt(Cont).display = ;
Cont++;
}
Grid_Amostra.dataProvider = ArrayTree;
}
public function CompleteEventHandler(evento:Event):void{
ArrayTree.getItemAt(Cont).display = Carrega;
}
i Saw some topics telling to use ByteArray but even after looking in the
other topics and the Livedocs. i still cant get how this thing works and
how is it gona help me
any help would be apreciated
[flexcoders] problem with Tree
Hi all,
I'm starting to work with trees using an Httpservice to connect to the
bank and return me this XML:
Root
node label='Bla1'
node label='Bla2'
node label='Bla3'
node label=Bla4/
/node
/node
/node
/Root
I set the property resultformat as XML and its returning Ok the XML.
the problem is when i use it as a dataprovider. the tree doesen't
shows the right thing, it shows de XMLcode inteasted of the
name(Bla1,BLa2,BLa3 and bla4)
My Mxml is like this:
mx:HTTPService id=dadosTree url=criatree.asp method=POST
showBusyCursor=true result=CriaTree(); resultFormat=xml/
mx:Tree left=0 top=0 bottom=0 right=0 id=TreeArtes
dataProvider={dadosTree.lastResult}/
Please help me a i dont know wath i'm doing wrong

with an answer as best I can:
1. It threw me a bit at first, but it makes sense once you look at
the types
returned by XML class. If an element of the XML has complex
content (i.e.
its not just straight text, but rather has additional XML elements or
structure), then referring to that XML element will always return an
XMLList. Thus, when you say for each (var s:XML in
data.lastResult.Tipos)
the XML class is returning an XMLList for all elements named
Tipos, which
in your sample data there is only one. If you want to iterate for
each of a
certain element, you specify that element in the for each like this:
for
each (var s:XML in data.lastResult.Tipos.Tipo). And to access them
directly
with an index, you'd use var s:XML = data.lastResult.Tipos.Tipo[0];.
2. To dynamically create UI components just new them (var
txt:TextInput =
new TextInput();) and then add them to the container
(addChild(txt);).
For dynamically creating forms the Form and FormItem components are a
lifesaver as they'll save you from having to do any formating
work. Your
code will end up looking something like this:
var form:Form = new Form();
var formItem:FormItem = new FormItem();
formItem.label = Some Field:;
var txtField:TextInput = new TextInput();
formItem.addChild(txtField);
form.addChild(formItem);
addChild(form);
3. You can load data from a ByteArray into things like the image
component.
Assuming you've already got the binary data pulled from the
database, and
assuming its in a format that Flash understands directly (SWF,
PNG, JPG,
GIF, etc.), you can use the loadBytes() method of the
flash.display.Loaderclass. This will give you a DisplayObject that you
can then use elsewhere as
you would traditionally use a dynamically loaded image.

the first problem is that it only loops once even tough there are 3.
the second is that i need to add components(TextArea, Image, Label,
etc.)on a Panel, but i must do it Using AS3 since its going to be
created based on the XML(i searched livedocs AND flex help but
didn't
find it).
the third one is the most tricky of the three, I an getting the
image
from the DB and its binary i need to send it into flex and use
it as a
kind of source to the Image component
PS: its not an URL its the data itself.
i know it can be rather confusing but please answer me even if
its to
say its impossible to do this.
