Hi, I'd like an example about simulation a "press key" operation in AS3 (AIR or Flex)

are you asking about how to dispatch key events?  that's possible, but you can't completely recreate a key press (like you can in VB).  basically, you can force an element with a listener to react as if a key had been pressed, but you can't recreate default behavior (you couldn't use fake key events to write in an input text field, for example).

the example above shows what you can do - as you can see, nothing is actually written to the textfield, and the keyCode returned is always 0 when dispatched programmatically

// create the textfield
var tf:TextField = new TextField();
tf.text = "some text";
tf.type = "input";
addChild(tf);

// define the handler
function keydownHandler(event:KeyboardEvent):void{
	trace(event.keyCode);
}
// set up the listener
tf.addEventListener(KeyboardEvent.KEY_DOWN, keydownHandler);

// "fake" a key press
tf.dispatchEvent(new KeyboardEvent(KeyboardEvent.KEY_DOWN));

Actually, it is possible to have textFields update as if a real key was pressed if you press down on the keyboard, but it requires a little tinkering.

A while back I helped someone get an onscreen keyboard working, which updates textFields based on which keys were "clicked". The post almost at the end is the complete one.

Do you need help adapting that code to your situation?

it's not possible to emulate a true key press, was my point.  of course you can add listeners and catch keycodes, then dynamically add text, but you can't simulate an actual key event - no web based technology allows this for obvious reasons (it would be a massive security hole).
