c# - Global Variables vs. ASP.NET Session State -

-

this going sound rather naive, i'm developing web application spans multiple pages. of these pages instantiate same class object w/ methods accesses cms using api. currently, when user starts creating content, i'm storing variables folder id content located in session variable.

my question this: can instantiate single instance of class can used across pages without having on every page? if so, each person accessing page given own version of class? assume using static variables , methods isn't way go since shared in memory. , also, where/how declared if going used globally in web application in .net c# application?

i recommend making base class inherits system.page. have page code behind inherit that.

then, inside base class, create property reference object. example, this:

   public class basepage : system.web.ui.page     {      public foo currentfoo             {                                 {                     return (foo)session["foosessionobject"];                 }                 set                     {                     if(session["foosessionobject"]==null)                     { //instantiate new 1                        session["foosessionobject"] = new foo();                     }                     session["foosessionobject"] = value;                 }             } }

then, anywhere in page, currentfoo. , have access of properties.

this makes nice , clean code behinds.

actionscript 3 - TweenLite does not work with object -

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
