How to take "print screen" from your FLEX application and save it to hard drive?

So I have such code for my application

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark" 
               xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">

    <fx:Script>
        <![CDATA[
            protected function prtscrn_clickHandler(event:MouseEvent):void
            {
                // save current RIA view as a PNG or JPG to users FileSistem
            }
        ]]>
    </fx:Script>

    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>
    <s:Button x="21" y="10" label="Print Screen" id="prtscrn" click="prtscrn_clickHandler(event)"/>
    <s:TitleWindow x="45" y="98" width="282" height="303">
        <s:CheckBox x="25" y="10" label="CheckBox"/>
        <s:Button x="24" y="44" label="Button"/>
        <mx:DateChooser x="24" y="76"/>
    </s:TitleWindow>
</s:Application>

I want to save Its something like "Print Screen" to users hard drive on button click.

How to du such thing?

Unfortunately you can't Print Screen the whole user's desktop, you can only "Print Screen" the flash file. Pseudo-code below:

var b:BitmapData = new BitmapData(stage.stageWidth, stage.stageHeight);
b.draw(stage);

// create reference that will be the saved file
var ref:FileReference = new FileReference();

// add listeners for filereference ...

// save the bitmapdata
ref.save(b.getPixels(b.rect));
