c# - Expression.DebugInfo How Do I Tag Expressions? -

-

so know expression.debuginfo used for, , have debug expression created, how tag other expressions debug info? here's i'm trying basic test:

    using system; using system.collections.generic; using system.linq; using system.text; using system.linq.expressions; using system.reflection;  namespace expressiondebugtest {     class program     {         static void main(string[] args)         {              var asm = appdomain.currentdomain.definedynamicassembly(new assemblyname("foo"), system.reflection.emit.assemblybuilderaccess.runandsave);              var mod = asm.definedynamicmodule("mymod", true);             var type = mod.definetype("baz", typeattributes.public);             var meth = type.definemethod("go", methodattributes.public | methodattributes.static);              var sdi = expression.symboldocument("testdebug.txt");              var di = expression.debuginfo(sdi, 2, 2, 2, 12);               var exp = expression.divide(expression.constant(2), expression.subtract(expression.constant(4), expression.constant(4)));             var block = expression.block(di, exp);              expression.lambda(block, new parameterexpression[0]).compiletomethod(meth);              var newtype = type.createtype();             asm.save("tmp.dll");             newtype.getmethod("go").invoke(null, new object[0]);             //meth.invoke(null, new object[0]);             //lambda.dynamicinvoke(new object[0]);             console.writeline(" ");         }     } }

i know debug info works compiled methods that's why i'm generating assembly on fly. when code causes "divide zero" error, it's not showing my "testdebug.txt" file

so seems missing debug info generator. code needed added: 

    var gen = debuginfogenerator.createpdbgenerator();      expression.lambda(block, new parameterexpression[0]).compiletomethod(meth,gen);

it works charm now!

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. ...
