timer - When does JavaScript interval stops? -

-

it may naive question need know answer.

this code,

setinterval(function() { /do stth./}, 1000);

i never cancel timer, need run long user on page, need know case memory leak, or when stop (ie, browser refresh, browser close)?

the problem can occur when "do something". if have other long running functions or additional intervals inside interval (a la javascript inception) run performace issues.

however, in cases, won't have problems.

when user refreshes browser, interval begin anew. when browser closed activity stops.

as long user doesn't refresh browser or leave page interval never end.

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.

c# - Cloning WPF controls and object hierarchies -

i have problems cloning object hierarchie. it's toolkit modelling applications, toolbox contains class instances prototypes. i'm having hard time cloning these :) the following code shows problem: public abstract class shape { protected list<uielement> elements; private canvas canvas; ... public canvas getcanvas() { ... }; } public class movableshape : shape { protected ... propertya; private ... propertyxy; ... } public abstract class abstractlayout : movableshape, ... { ... } public class somelayoutclass : abstractlayout, ... { ... } public class acontainingclass { somelayoutclass layout { get; set; } ... } when insert object of acontainingclass project worksheet, should cloned. far tried manual cloning (which fails because of private fields in base classes) , binary serialization ( binaryformatter , memorystreams ). the first approach lacks way call base.clone() method (or wrong?), latter not work because uielement s aren't...
