I am trying to open a 16 bit tiff image in my AIR app. What I have found is a baseline decoder which supports only 8 bit images. Here are my options:Extend its functionality to open 16bit images but I dont know how to dothat and how trivial it is.Open my images as 8 bit but I need todo that automatically within Flex.Dont know how to do that either.i also need to support lzwcompression for tiff

I've been able to create a program that can convert single codons. But can not handle multiple, and only takes the last value. So if I typed "UUG UAA" it would give me STOP. My current code looks like this:

I am developing a Image uploader using Flash 10. I am using Filereference object to browse images and Loader to show the image:
Sample code:
var tempFileRef:FileReference = FileReference(ev.target);
var oLoader:Loader = new Loader();
oLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onImageLoad);
oLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, onIOError);
oLoader.loadBytes(tempFileRef.data);
It works fine with .jpg and .gif files but when I browse .bmp or .tiff file, I am getting the error:
Error #2124: Loaded file is an unknown type.
Is there a way to load and display browsed .bmp images from desktop?
where I can find info about compiling flex 4.0 sdk on flex 4.5/4.5.1 sdk.I am having troubles. compilation goes well on 4.0 but whe I compile on 4.5 or 4.5.1 I get blank swf.
Note: I have set flash player 10.2 for compilation and also as default.
If I create an object like so:
class Foo {
[Bindable] public var property: String;
}
The class Foo has an implicit event dispatcher to handle property change events. How can I access that without making Foo explicitly extend EventDispatcher?

View 1 RepliesI have implemented application client-server with spring blazeDs message services using JMS message destination. The idea is a producer declared in Java send message using activeMQ and consumer declared in Flex receives them. I have configured the AMFChannel with a polling interval 0, but I have seen when the consumer subscribes to the destination in Flex, the time request can be of up to 3 seconds.

View 1 RepliesI am trying to access html files protected by basic authentication. Below is the code to do that but I still get the authentication dialog. I checked the fiddler and found that for the first request authorization header is present but for the subsequent requests which is requested to load the .js, css & images the authorization header is not added. This is the reason I am getting the auth dialog.
Is there a way to add authorization header to the subsequent requests as well?

I have a TabNavigator, and each tab is a Module. One of the modules is labelled Units and the full code of the module is posted in this post. There are several problems:
1) Forms are not populated with data from the datagrid selection.
2) Selecting a row and clicking delete gives the very-common error: TypeError: Error #1009: Cannot access a property or method of a null object reference.
A trace on the valueObject unit within the selectionChangeHandler function gives NULL. Why? Note: In other modules (other tabs of the TabNavigator), I have DropDownLists populated with units. This means that the valueObject Unit is defined in the other modules. However, valueObjects should be private to modules, and not shared.

I am working on a grid example in flex using advanced grid control. I know we can easily group data by specifying the field name. At the group node level, other than the gorup name I want to be able to show data in the rest of the cells ( calculated data ) and I am looking for some dataRowBound event or similar to be able to hook some data in it.
Example: Grid displaying list of towns grouped by state. At the group level ( for each state) I want to show the total number of towns in each state. Here how can i show the total number in the town column.
I've embedded a MovieClip symbol with the [Embed] syntax into my AS3 project, which I'm compiling with the Flex 3 SDK.

I am writing a Flex application for use on a private intranet with no external Internet access. I want to use Google's 3D Maps Flex API, but it must be connected to the internet to download map tiles on demand.

I am currently developing a dynamic LineChart in FLEX 4.I am implementing a Tree control next to my LineChart, which will filter the LineChart dataprovider and lineseries. The tree control has several branches and ultimately 5 children (leaf nodes) at the bottom of the last branch.I need the leaf node/children to be displayed as checkboxes inside the tree control.As I understand,this will require overrides in the TreeItemRenderer class.This is where I am a little confused on how to implement that.Currently I can distinguish between leaf and branches using this code, in my main MXML component.I added this because it may be helpful to some beginning FLEXdevelopers, such as myself, who cannot easily find this functionality documented well:
private function treeClick(e:ListEvent):void {
_selectedItem = Tree(e.currentTarget).selectedItem;
if(mainTree.dataDescriptor.isBranch(_selectedItem)) {[code].....
I am looking at the TreeItemRenderer override class from the following example here: In the example, they override the "createChildden" super function to add checkboxes to the tree control.My question is, can I override the createChildren function directly in my MXML component, and not have to use an entire class file to override this functionality? Must I re-invent the wheel to do this?Also, how can I distinguish that my treeItem is a leaf node and not a parent, in the override function? I only want to add checkboxes to the leaf nodes, how can I differentiate? The following example adds checkboxes to all branches and leaf nodes, but I want to add checkboxes only to leaf node/children. How would you approach that?
override protected function createChildren( ): void
{
super.createChildren( );[code]............
Here is my tree tag:
<mx:Tree id="mainTree" dataProvider="{treeData}" itemRenderer="TreeCheckBoxItemRenderer" labelField="@label" showRoot="false" width="100%" height="100%" itemClick="treeClick(event)" />
My company want to develop an online multitouch scrumboard for our scrumteams. We are still in doubt between flex and silverlight as platform for the application. (don't want to fire a hole new flex vs. silverlight discussion again) Installation rate & platform independence are not critical to us, because it's just for teammembers and only windows 7 enables multitouch events in flash or silverlight.We would like some pros/cons specifically for this project (multitouch, rich user interface, integration with backends).[code]

How can I programmatically click the browser's Back button from within my Flex application. I'm using deep linking to allow the user to navigate back/forth inside my application. I want this to work when BACKSPACE is clicked inside the application as well, but Flex captures BACKSPACE and the browser doesn't get the event. I don't want to implement browsing history myself within the application, naturally. Can I send BACKSPACE to the containing browser?
