flash - How to use a new movieClip as a Class or to copy it without reference to its class? -

-

i doing looping background 2 identical bg movieclip (b1 , b2). 2 "new" same class.

var b1:movieclip = new bg(); var b2:movieclip = new bg();

but because bg class picture loader internet , picture rather big. when addressed loading using progressevent. picture loaded 2 times. there anyway create b2 based on b1 without using new bg() again? since makes new bg loader code inside. thank ^^

for bg class code:

var urlvar:urlrequest; var bgloader : loader = new loader( ); urlvar = new urlrequest( "somewherelink.jpg" ); bgloader.load(urlvar); this.addchild(bgloader);

is there way set if b1 loaded, copy b2? or other way achieve same goal?

import flash.display.*; import flash.utils.*; var obj:class = getdefinitionbyname(“bluebox”) class; addchild(movieclip(new obj()));

i found 1 in dynamically create class, dunno how use t_t, can explain me , can use in situation? thank time ^^

for answer i'm going assume going want have same image twice, rather 2 different ones. problem have bg class load , attach internally. preferred approach load once, , create instances of loaded content.

//first lets create single loader var bgloader:loader = new loader(); bgloader.contentloaderinfo.addeventlistener(event.complete,completehandler); //and load content var urlvar:urlrequest = new urlrequest("somewherelink.jpg"); bgloader.load(urlvar); //notice don't add loader stage  function completehandler(evt:event):void {     //remove loader listener memory conservation purposes     evt.target.removeeventlistener(event.complete,completehandler);     //reference content     var content:displayobject = evt.target.content;     //so create bitmapdata object     var bmd:bitmapdata = new bitmapdata(content.width,content.height,false); // use (content.width,content.height,true,0) if loading image transparancy     //and draw loaded image bitmap data     bmd.draw(content);     //now can create many bitmap objects data     var bg1:bitmap = new bitmap(bmd);     var bg2:bitmap = new bitmap(bmd);     //offset bg2 both visible     bg2.x = 100;     addchild(bg1);     addchild(bg2); }

for second question... getdefinitionbyname returns object represents named class, rather instance of it. in example, getting definition class 'bluebox', in root of application source (not in folder).

once have class object can create instances of new keyword. big disadvantage of far i'm concerned don't import class, hence in example obj cast movieclip. makes features of code editors code completion , error highlighting not work correctly because properties , methods of 'bluebox' not exposed.

i use creating objects have classes defined elsewhere, in xml file loaded @ runtime example.

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...

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values? (the array 7 rows 9 columns, btw). mov cx, 7; cx = number of rows outer: ; outer loop walk through rows push cx mov cx, 9 mov row, cx ;rows middle: ; middle-loop walk through columns push cx sub cx, 1 ;cx = cx-1 mov column, cx ;columns inner: ;inner loop - compare , exchange column values cmp marray[row*9 + column], marray[row*9 + column+1] xchg marray[row*9 + column+1], marray[row*9 + column] ; compare , exchange values marray table inc column loop inner pop cx loop mid...
