i have entity type property type list of b. type b has property of type list of c. i want apply filter on object of such there c objects in list of c selected property true. this can done like: a obja = a.listb.foreach(b => {b.listc.removeall(c => c.selected == false);}); but don't have remove c objects have selected = false. want filter them. any ideas? more explanation: there object of type a, list of b property. in each b object of a's list of b, there exists list of c property. c object has selected property. now, need is- object of list of b, in each of b's list of c has c objects have selected = true. desirable output type a. list b shouldn't filtered list c needs filtered. what this: a.listb.where( b => b.listc.exists( c => c.selected ) ) is want?

i understand differences between fork, vfork, exec, execv, execp. pls dont rant it. question design of unix process creation. why did designers think of creating 2 seperate calls ( fork , exec ) instead of keeping 1 tight call ( spawn ). api design reason developers had more control on process creation? because of performance reason, delay allocating process table , other kernel structures child till either copy-on-write or copy-on-access? the main reason separation of fork() , exec() steps allows arbitrary setup of child environment done using other system calls. example, can: set arbitrary set of open file descriptors; alter signal mask; set current working directory; set process group and/or session; set user, group , supplementary groups; set hard , soft resource limits; ...and many more besides. if combine these calls single spawn() call, have have complex interface, able encode of these possible changes child's environment - , if ever added new se

is possible use objective-c++ ios application (iphone, ipad, ipod touch) development? are there examples , source code on internet? using objc++ quite easy. have declare source files extension .mm. make compiler treat them objc++. same headers: use .hh extension. there option: go target settings , set compile sources objective-c++. that's all. no additional work necessary. some notes: if want develop native ios app, use objective c. save lot of time. in cases using c++ more appropriate. e.g. cross-platform development. use little bit of objective c iphone or java android glue code environment. else in c++. use cross-platform game development. another case performance: objective c principally slower c++. noticeable during method calls (in objc called messaging).

if use managed addin framework (system.addin) , set use separate appdomains, can use centralized ioc container in primary/default appdomain? can ioc container resolve across appdomains? i'm going approach answer ignoring maf part of equation, , concentrating on appdomain issue. ioc container theoretically describe, assuming ioc entry point inherits marshalbyrefobject or wrapped class in turn inherits marshalbyrefobject. 29k+ rep score, sure know but: 1) objects inherit marshalbyrefobject can accessed across appdomain boundaries via proxying (that is, of calls marshalled across appdomain boundary object). 2) objects serializable can passed across appdomain boundary via serialization, is, can copy of them in other appdomain. for number of reasons, wouldn't want serialize whole ioc container , ship across appdomain boundary. first off, overhead of doing enormous, , secondly there lot of plumbing behind ioc container isn't serializable. therefore possibl

context big project multi maven module or single maven module structure question did use multi-maven-module or single-maven-module structure? details if you've worked on big project had long development duration , contains lots of functionality(i.e. not trivial project), did choose split project multiple maven modules or went single-module approach? for example, having multi-module structure, crashes when running maven commands mvn gwt:eclipse(see http://bit.ly/gs4rmo ). guess have worked single module gwt project. , there other commands above has issues multi-module structure. however, multi-module structure bring benefits of faster development, i.e. if separate "server" "client" module, compile business logic(server) separately , package resulting web archive. compiling gwt code, takes 20 seconds, if modify server package, save lots of time in long run. which other cases 1 above did encounter when working multi-module/single module proj

i'm trying come scalable way link 2 edit text boxes unit conversion. user enter value in either of boxes , converted value show in other. i make when 1 edittext edited, input, pass through method convert value , set text of other field. the problem have lot of these pairs , each pair used convert different kind unit. if used textwatcher each box, can see start out of hand. i thought extending textwatcher pass edittext view , partner's view, i'm not sure how pass kind of conversion method needs used. assign int each kind of conversion , use switch, doesn't seem solution me. is there better way? this how it. create class, partneredittextinfo ,which contains reference number , edittext obj. attach tag every edittext in app. set edittext in partneredittextinfo partner edittext , have unique reference number. every edittext can hold of partner. extend edittext class , on ride ontextchanged() method call common conversion method(this can static class st

how can dependably verify existence of folder using msbuild extension pack task? how without throwing error , stopping build? could use exists condition on target? this execute onlyifexists target if there directory or file called testing in same directory msbuild file. <itemgroup> <testpath include="testing" /> </itemgroup> <target name="onlyifexists" condition="exists(@(testpath))"> <message text="this ran!" importance="high" /> </target>

i have .json file approx. 1.5mb in size containing around 1500 json objects want convert domain objects @ start-up of app. currently process on phone (not on development pc) takes around 23 seconds far slow me , forcing me write list of objects applicationsettings dont have each time app loads (just first off), takes 15-odd seconds write to, , 16 seconds read from, of not enough. i have not had lot of serialization experience , dont know fastest way done. currently, using system.runtime.serialization namespace datacontract , datamember approach. any ideas on performance type of data loading? i found json.net library more performant , have better options standard json serializer. one performance issue encountered in app domain objects implemented inotifypropertychanged code support dispatching event ui thread. since deserialization code populated properties doing lot of thread marshalling didn't need there. cutting out notifications during deserialization

my professor asked me these 2 labs, , finished first 1 not know how second one. write person class contains following fields , methods: first name, last name, unique id number should assigned starting 1001. methods return information , tostring method returns neatly formatted string describing key attributes of person. i finished 1 above. public class person { private string first; private string last; private static int idnumber = 1001; int id; private string full; person(){ first = "john"; last = "doe"; int idnumber; full = first +" "+ last; } person(string fn,string ln){ first = fn; last = ln; id = idnumber++; full = first +" "+ last; } static int getidnumber(){ return idnumber; } void setfirst(string fn) { first = fn; } string getfirst(){ return first; } void setlast(string ln){ last = ln; } string getlast(){ return last; } @override publi

we consuming web services. use wsdl.exe generate client proxy. how keep underlying xml files proxy sends , receives web services provider? the purpose protect ourselves showing did have send parameters in format when system malfunctions , disputes arise. we did using soapextension in application making web service requests. the entire system consisted of 2 classes, copystream class provided ability duplicate contents of stream second stream read / written to, , soaplogger class intercepts soap requests , responses in application , logs them file. you need register in app.config file: <configuration> <system.web> <webservices> <soapextensiontypes> <add type="mynamespace.soaplogger, myassembly" priority="3" group="high" /> </soapextensiontypes> </webservices> </system.web> </configuration> apologies big blob of code, here is: /// <summary>

i have form x number of fields. when submitted, want to; get input data, $var = $_post['input'] validate input, (!empty($var) && is_numeric($var)) stick in array, array_push($myarray, $var) generate urls, $url.=$var process url's without leaving page 1 - 4 done in php simply, im not familiar ajax. been decade since ive touched javascript. im not sure if should using javascript whole process. however, prefer php validate, ajax http requests. sample code/sites available passes php var's/array ajax handle http requests? you'll want use kind of format pass data server client. recommend json . php has a built-in function encode array it, , javascript parses natively. as ajax part itself, recommend using framework jquery. makes way simpler, , don't have deal different browsers yourself. $.ajax({ url: "yourpage.php", success: function(data){ alert(data); } });

say have c++ class like: class foo { public: virtual ~foo() {} virtual dosomething() = 0; }; the c++ compiler translates call vtable lookup: foo* foo; // translated c++ to: // foo->vtable->dosomething(foo); foo->dosomething(); suppose writing jit compiler , wanted obtain address of dosomething() function particular instance of class foo, can generate code jumps directly instead of doing table lookup , indirect branch. my questions are: is there standard c++ way (i'm sure answer no, wanted ask sake of completeness). is there remotely compiler-independent way of doing this, library has implemented provides api accessing vtable? i'm open hacks, if work. example, if created own derived class , determine address of dosomething method, assume vtable first (hidden) member of foo , search through vtable until find pointer value. however, don't know way of getting address: if write &derivedfoo::dosomething pointer-to-member, totally diffe
