as activity students, have set of draggables need matched set of droppables. code below works fine (for example allows student change selection) allows student put 2 draggables on 1 droppable. $('.drags').draggable({containment:'#container', revert:function (event, ui) { $(this).data("draggable").originalposition = {top: 0,left: 0 }; return !event;}}); $('.drops').droppable({accept:'.drags', drop:function(event, ui){ ui.draggable.position( { of: $(this), my: 'left top', at: 'left top'} );},}); if disable droppable, including following code in 'drop' function $(this).droppable({ disabled: true }); then draggable disabled not w...

possible duplicate: when need use 1-to-1 relationship in database design? relational databases/sql: typical use cases one-to-one parent-child (non-inheritance, tree-like self/super table) relationships? of course, implement/become parent-child list instead of tree (assuming regular one-to-many). think sports leagues, see http://en.wikipedia.org/wiki/english_football_league_system : english premier league (soccer) of same type league (single) child, football league championship . @ lower point can see children "split" conference north , conference south . can modeled many-to-one relationship league league , resulting in regular tree. if changed described many-to-one parent-child relationship one-to-one, list instead of tree, top part of english soccer leagues. i'm asking for. consequence children of node become child or next element (because of fact list now). i wonder when regularly need list structure in relational databases, given are t...

i had problems using c#, nhibernate , link. in example bellow, select in brandtable, need "name" , "id" columns. select columns of table. using entityframework, same code bellow generates select 2 columns. how in nhibernate? using (isession session = myconnection.getcurrentsession()) { var brands = b in session.queryover<brandtable>().list() orderby b.name select new brand {id = b.id, name = b.name}; return brands.tolist(); } you can't use query comprehensions queryover, because not linq provider. in example you're selecting records, , using linq objects. add nhibernate.linq namespace file , rewrite query from b in session.query<brandtable>() orderby b.name select new brand {id = b.id, name = b.name};

i'm implementing binary translation , have deal sequences of nops (0x90) length 16 opcodes. better performance place jmp (to end) @ start of such sequences? the intel architecture software developer's guide, volume 2b (instructions n-z) contains following table (pg 4-12) nop : table 4-9. recommended multi-byte sequence of nop instruction length assembly byte sequence ================================================================================= 2 bytes 66 nop 66 90h 3 bytes nop dword ptr [eax] 0f 1f 00h 4 bytes nop dword ptr [eax + 00h] 0f 1f 40 00h 5 bytes nop dword ptr [eax + eax*1 + 00h] 0f 1f 44 00 00h 6 bytes 66 nop dword ptr [eax + eax*1 + 00h] 66 0f 1f 44 00 00h 7 bytes nop dword ptr [eax + 00000000h] 0f 1f 80 00 00 00 00h 8 bytes nop dword ptr [eax + eax*1 + 00000000h] 0f 1f 84 00 00 00 00 00h 9...

if class private , constructor public happen. can create instance of class or other class can extend? need know why , when people create private class public ctor? the code like private class lazyresource { somebigresource _heavyobject = null; public somebigresource lazyload { { if (_heavyobject == null) _heavyobject = new somebigresource(); return _heavyobject; } } } plzz guide me thanks you can't create non-nested private class in c#. this nested class, in case containing type can instantiate instance of it. , if lazyresource had private constructor nothing able instantiate (except static member of lazyresource itself).

i have divs floating left, if see attached jsfiddle see im trying do, in fiddle there yellow box, need flush bottom of green box im not sure if possible? is it? , if how may this? in advance! http://jsfiddle.net/k5zjc/ try this jsfiddle . techincally, float .box items right instead of left , getting self-filling columns in accordance content. so, in css add: .box:nth-child(odd) {clear: left} .box:nth-child(even) {float: right; clear: right} update apparently solution doesn't work nice if have more these specific blocks. so, probably, jquery masonry way result.

how code in javascript executed? mean in order? there difference in order of execution if declared function this: function render() { // code here } instead of this: var render = new function(){ // same code here } does javascript execute functions defined in scripting file regardless of whether they're called event handler? (e.g. onload=function() ). and if function defined in function, when parent function called, lower function called too? e.g. function a(){ function b(){ // code } function c(){ //code } } i'm trying concrete understanding of order of execution in javascript. var render = new function(){ // same code here } the new keyword doesn't create new function. creates new object running function. run body of method , return object instead. if asking when functions parsed , added scope that's implementation specific, functions hoisted top of scope , parsed before code executed. ...

i wondering if synthesize has sort of support dot syntax. goal here learn more - realize can achieve goal defining getter myself. have been looking info on topic without success far. example of want do: @synthesize name = self.someobject.name; which, getter, along lines of: -(nsstring*)name { return self.someobject.name; } no, can't this. value after = in @synthesize must reference ivar of current class. you're free implement above getter you've noted, @synthesize won't it.

i’m relatively new working scala having come java background. i’m seeking advice on creating efficient s means of reading xml file , extracting element names , properties contained within data enclosed between parentheses. for example < name >{property}< name/ > so key there data contained within {} i want populate hash map actual element names , property values contained between {} . i’m sure not overly complex given limited scala expertise @ time i’d bounce question off expertise within forum. many taking time answer. [updated] realized you've asked braces in text, not xml-related syntax braces. possible answer is: scala> val xml = <a> <prop>{{key1}}</prop> <prop>{{key2}}</prop> <prop>notkey</prop> </a> xml: scala.xml.elem = <a><prop>{key1}</prop><prop>{key2}</prop><prop>notkey<...
