External SWF dissapears afte sometime

hi there!

 

i have preloader preload swf file, works fine, except, when run html file on browser, external swf file dissapears after 1-2 minutes,

basically, put preloader (swf file), on html code, , preload external swf.

this code:

 

import flash.geom.*

import flash.display.*

 

var loadurl:string = "external.swf";

var ndepth:number = 0;

var nwidth:number = 200;

var nheight:number = 20;

var cloader:moviecliploader = new moviecliploader();

var olistener:object = {onloadinit:oncontentloaded};

var mcloader:movieclip = this.createemptymovieclip("loader_mc", 0);

var mccontent:movieclip = this.createemptymovieclip("content_mc", 1);

var cmatrix:matrix = new matrix();

 

cloader.addlistener(olistener);

 

txtpercload = mcloader.createtextfield("percload_txt", ndepth++, 0, 0, nwidth, nheight);

mccontent._alpha = 0;

mccontent._lockroot = true;

mcloader._x = stage.width/2 - mcloader._width/2;

mcloader._y = stage.height/2 - mcloader._height/2;

txtpercload._x = mcloader._width/2 - txtpercload._width/2;

txtpercload._y = mcloader._height/2 - txtpercload._height/2;

cloader.loadclip(loadurl, mccontent);

 

_root.onenterframe = function()

{

   var nbytesloaded:number = mccontent.getbytesloaded();

   var nbytestotal:number = mccontent.getbytestotal();

   var npercloaded:number = math.round(nbytesloaded / nbytestotal * 100);

   if(npercloaded > 0)

   {

      settextformat(txtpercload, npercloaded.tostring() + "%");

   }

}

 

function oncontentloaded(void):void

{

   settextformat(txtpercload, "100%");

   cloader.removelistener(olistener);

   delete _root.onenterframe;

   delete olistener;

   delete cloader;

   _root.onenterframe = function()

   {

      //trace(_root + "::oncontentloaded::_root.onenterframe");

      var ninc:number = 5;

      mcloader._alpha -= ninc;

      mccontent._alpha += ninc;

      if(mcloader._alpha <= 100) {mcloader.removemovieclip();};

   }

}

 

 

 

function settextformat(txtfield:textfield, stext:string)

{

   var txtfmt:textformat = new textformat();

   stext = "loading content " + stext;

   txtfmt.font = "arial";

   txtfmt.align = "center";

   txtfmt.size = 12;

   txtfmt.color = 0xff0000;

   //txtfmt.bold = true;

   txtfield.selectable = false;

   txtfield.text = stext;

   txtfield.settextformat(txtfmt);

   txtfmt = null;

}

 

 

please let me know doing wrong? in advance

if keep eye on value of mccontent._alpha, you'll see because never shut off second onenterframe function, _alpha property continues go until reaches maximum , flips negative, means goes invisible.  confirmed running code.

 

i don't know limit is.  in actionscript, when number limit reached common advance opposite limit - looped numeric system.
