This is an example how to create a typeing effect without having to use masks. (you can repeat the text or add a pipe character )


import mx.utils.Delegate;

class myfolder.typingText { // replace myfolder with the folder structure you use
private var delayTime:Number;
private var destinationMc:MovieClip;
private var messageText:String;
private var currentChar:Number;
private var includePipe:Boolean; // include pipe character after text
private var doRepeat:Boolean; // repeat typeing after 5 sec

public function typingText(mcBot, mcRoom){
this.delayTime = 50;
this.destinationMc = null;
}
public function typeText(){
var dest = this.destinationMc;
if (dest && dest.html != null) {
dest.html = true;
dest.text = this.messageText.substr(0, this.currentChar);
if(this.includePipe)
dest.text = dest.text + "|";

this.currentChar++;
if (this.currentChar > this.messageText.length) {
if(this.doRepeat){
this.currentChar = 1;
_global.setTimeout(Delegate.create(this,typeText),5000);
}
} else {
_global.setTimeout(Delegate.create(this,typeText),this.delayTime);
}
}
}
public function startTyping(textParam, delayParam, destinationParam, repeat , pipe){
this.messageText = textParam;
this.delayTime = delayParam;
this.currentChar = 1;
this.destinationMc = destinationParam;
this.typeText();
this.includePipe = pipe;
this.doRepeat = repeat;
}

}

Insert in flashdocument:

import myfolder.typingText

var myText = "Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Sed vel est. Cras convallis quam non diam. ";

// textarea
var typing1 = new typingText();
typing1.startTyping(myText,200, taTypingText,true, false );
// dont use pipe in text area because a CR is generated and pipe end up under the last line

//inputtext
var typing2 = new typingText();
typing2.startTyping(myText.substr(0, 40),80, tiTypingText, true, true );

// textfield
var typing3 = new typingText();
typing3.startTyping(myText,500, dtTypingText, false, false );

Example:

For javascripters it is well know that IE browsers have problems with memory leaking.. but this problem took me while to find..

On several sites I attach events based on the classname of an element. I have to remove these attached events on unload. So I did. but somehow I always have one element leaking in IE ( mostly an element that i didn’t attach anything on it, so that puzzled me) 

The problem was in the getEvent function I used to convert a fired event to W3C standard. this was my code:

function getEvent(e) {
 if (e == null) {
  e = window.event;
 }
 if (e == null) {
  return null;
 } 
if (!e.target) {
  e.target = e.srcElement;
 }
 // get parent if nodetype is textnode
     if (e.target.nodeType == 3) {
     e.target = e.target.parentNode;
 }
 if (!e.stopPropagation) {
  e.stopPropagation = function() {
   e.cancelBubble = true;
  }
 }
 if (!e.preventDefault) {
  e.preventDefault = function() {
   e.returnValue = false;
  }
 }
 return  e;
}
 

But calling this function caused the leak.
when I changed this function to this underlying code the leak was gone…….hooray!!!


/**
* Returns an event object that is normalized for cross-browser support.
*
* @param {Event} e Event object. Is allowed to be null.
* @returns {Event} A normalized event object.
*/
function getEvent(e) {
    if (e == null) {
  e = window.event;
 }
 if (e == null) {
  return null;
 }
 if (!e.target || !e.stopPropagation || !e.stopPropagation) e = W3CEvent(e);
 
 return  e;
}

/**
* Returns a synthetic event object with partial compatibility with W3C events
*
* @param {Event} e Event object.
* @returns {event} The partial W3C event object.
*/
function W3CEvent(e) { 
    if (!e) e = window.event;
    var event = {
        _event: e,              // In case we really want the IE event object
        type: e.type,           // Event type
        target: e.target?e.target:e.srcElement,   // Where the event happened
        relatedTarget: e.fromElement?e.fromElement:e.toElement,
        keyCode: e.keyCode,
       
        // Mouse coordinates
        clientX: e.clientX,
        clientY: e.clientY,
        screenX: e.screenX,
        screenY: e.screenY,
       
        // Key state
        altKey: e.altKey,
        ctrlKey: e.ctrlKey,
        shiftKey: e.shiftKey,
        charCode: e.keyCode,

        // Event management functions
        stopPropagation: function(){this._event.cancelBubble = true;},
        preventDefault: function(){this._event.returnValue = false;}
    }
    return event;
};

why???? if someone can tell me why please respond..

When you want a folder to be back-upped inside a folder with a datename for version control. It is very easy to do this with apple’s own automator.Go to automator (in your application folder or with right mouse click on a finder element -> more -> automator)  and select the following actions:

• Ask for Finder Items 
• Create Archive
• New Dated Folder

Enter a name for your zipfile in the create archive folderchoose a dateformat in the new date folder actionselect ‘move passed items to the new folder’ in the new date folder action.and your done.
