i saw assembly code like, mov [eax], ebx the above line, mentioned [eax] memory , ebx register. so, here difference between [eax] , ebx . happen in above instruction. in syntax, brackets around register means memory location used (as source or destination, according instruction) starting address specified @ register (eax in case). example, if eax contained 1344 before instruction, value ebx copied logical memory addresses 1344-1347 (because 4 byte copying). i hope enough untangle them in mind:) , please notice more complex cases possible (e.g. mov [eax+ecx],ebx forms destination address sum of 2 register values).

i've heard shouldn't use foreach loop can avoid because can cause thread concurrency, mean thread concurrency, , true ? so when should use for-each loop? any time can . beautifies code. unfortunately, cannot use everywhere. consider, example, the expurgate method . program needs access iterator in order remove current element. the for-each loop hides iterator, cannot call remove . therefore, for-each loop not usable filtering. it not usable loops need replace elements in list or array traverse it . finally, it not usable loops must iterate on multiple collections in parallel . these shortcomings known designers, made conscious decision go clean, simple construct cover great majority of cases. emphasis mine. unless clear mean exactly, indicate you're wrong.

i have several user controls have similar functionality, thinking moving these methods baseusercontrol class , , make user controls inherit it. however, when so, compliler warning: base class baseusercontrol specified class usercontrol1 cannot different base class system.windows.forms.usercontrol of 1 of other partial types i know i'm getting warning because when create baseusercontrol , autogenerated code in designer adds inheritance system.windows.forms.usercontrol . so, 1. how can inherit `usercontrol` in `vb.net`? 2.is possible? if not, how avoid code repetition in case? thanks!

i use phpstorm on mac using deployment function sftp. today noticed, file permissions lost when that. of local files have execution bit set, not set on remote server. in deployment options have disabled "override default permissions" , did not have enabled ever before. what do? googled world not find hooks deployment process of phpstorm. automatically triggering deployment on save instance. found solution rsync , phing ( http://www.ibresources.com/technical/programming/rsync-with-phpstorm ), solution, have press key, not want ( lazy bitch, know ;-) ). if there no solution upload manually rsync, keeps permissions , rely on rest of deployment features of phpstorm. "upload"-function useless then. does face same problem? it? cheers, thomas i realize old thread. however; to preserve rwx permissions of files on upload can defined in phpstorm settings | build, execution, deployment | deployment | options . you need activate check box "overri...

i have partial view want display different type of html element based on property of model. solution i've come is: @if (model.element == "span") { <span> stuff </span> } else if (model.element == "p") { <p> stuff </p> } else { <div> somestuff </div> } this not extensible. i'd write like: <@model.element> stuff </@model.element> but doesn't seem allowed. there way this. (i appreciate goes against grain of mvc model , therefore controller specifying html. actually, element type comes parent view, think okay.) many in advance. @html.raw("<" + model.element + ">") stuff @html.raw("</" + model.element + ">") is simple possible. though use tagbuilder : @{ tagbuilder tb = new tagbuilder(model.element); tb.innerhtml = "some stuff"; @html.raw(tb.tostring()) }

i want compare number of items in 2 select elements(html). tried using length property(with jquery) says both select element have number of option =1. populating both select elements dynamically. do? var $options=$("#test_select"); $options.empty(); $.each(t_test_list,function(index,value){ $options.append($("<option>").text(value).attr("value",value)); }); var numdate=$("#date_select").length; var numtest=$("#test_select").length; alert(numdate); alert(numtest); if(numdate!=numtest) { alert("the number of dates not match test cases!!!"); } try this: change: var numdate=$("#date_select").length; var numtest=$("#test_select").length; to: var numdate=$("#date_select").children('option').length; var numtest=$("#test_select").children('option').length; you need options length children of select not sele...

i have wrong , not working. i'm trying call 1 shared function alert data passed called 2 different click events |i underfined in alert. why underfined? var myf = function(){ alert('a click ' + this.model + ' ' + this.year); // meant alert properties of object passed alert(this.id); // meant alert id of click called }; var mycar = new object(); mycar.make = "ford"; mycar.model = "mustang"; mycar.year = 1969; var mycar2 = mycar; mycar2.make = "vw"; mycar2.model = "golf"; mycar2.year = 2000; $('.feature1').click(mycar,myf); $('.feature2').click(mycar2,myf); to access data in event handler, must use event.data : var myf = function(e){ alert('a click ' + e.data.model + ' ' + e.data.year); alert(this.id); }; moreover, property contains id called id , not id . , have typo mycar2 = mycar instead of mycar2 = mycar . demo

field validation works easy enough in vaadin, can't use check relations between fields (e.g. joining date must before leaving date), annoying. added standard class level validation using jsr 303 can this. works fine. but can perform cross field validation after have commited fields. means bean contains field changes, , in case of validation issue need possibility "go back" valid state before field commits (or force somehow "reload" of bean), else i'm stuck changes, e.g. if user decides cancel edit action. of course save field contents before, , reset state manually, given vaadin same in case of simple field validation i'd reuse mechanism. looking @ vaadin code, i'm not confident can figure out do, , right. please give me hints how deal problem without reinventing wheel. you can add commit handler fieldgroup . allows check before/after commitment: binder.addcommithandler(new commithandler() { @override public void preco...
