How to make "open file" function

Question

Is there a method that you can call that can prompt the user to open a file? Here is what I have:
var file:FileReference = new FileReference;
var newFile:BitmapData = new BitmapData (600,290,false);
newFile.draw(file.upload(file.browse()));
var s:Shape = new Shape();
s.graphics.beginBitmapFill(newFile);
s.graphics.drawRect(0, 0, board.width, board.height);
s.graphics.endFill();
board.addChild(s);
What would I put in the line in bold to achieve this?

How do I convert the File Reference to the bitmap data or a shape? This is what I have right now:
var file:FileReference = new FileReference();
var newFile:BitmapData = new BitmapData(600,290,false);
file.browse();
var selectedFile:FileReference;
file.addEventListener(Event.SELECT, file);
function f(e:Event)
var selectedFile = FileReference(e.target);
newFile.draw(e.target);
var s:Shape = new Shape();
s.graphics.beginBitmapFill(newFile);
s.graphics.drawRect(0, 0, board.width, board.height);
s.graphics.endFill();
board.addChild(s);
