actionscript 3 - Is it possible to load a non-Document Class before preloader starts? -

- 

public class framework extends movieclip {     var _loadingsystem:loadingsystem;      public function framework()      {         _loadingsystem = new loadingsystem(this);         loaderinfo.addeventlistener(progressevent.progress,progresshandler);         loaderinfo.addeventlistener(event.complete, completelistener);     }

...

public class loadingsystem extends movieclip {      public function loadingsystem(parent:displayobjectcontainer)      {         parent.addchild(this);          mylogo.buttonmode = true;         mylogo.addeventlistener(mouseevent.click, gotomysite);      }

as can see, framework doc class creating _loadingsystem movieclip contains preloader graphics. when debug following error "typeerror: error #1009: cannot access property or method of null object reference." pointing mylogo.buttonmode = true;

from understand due loadingsystem not being loaded before being created in framework. there way me make work? have tried adding listeners event.added didn't work.

additional info: 3-frame fla, first empty stop, second holding assetholder movieclip, third application. have export on 2nd frame set in publishing settings, checkboxes export on 2nd frame unchecked in assets, , worked before changed export on 2nd frame setting except wasn't preloading 50% of file.

i think what's happening this:

a document class loaded in first frame, because represents swf root class , has there in first frame. now, since export other classes frame 2, imagine, loadingsystem existing beginning frame two, try instantiate in constructor of document class framework.

what try out is, create method "initialize" in framework , call timeline in frame 2. , in method stuff, in constructor of framework.

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
