this question has answer here: javascript closure inside loops – simple practical example 31 answers i trying use value of loop counter inside queued function, example: for(var i=0; i<5; i++) $(document.body).queue(function(){alert('i=' + i); $(this).dequeue();}).delay(1000); then get: i=0, i=5, i=5, i=5, i=5 i think because i has changed while delay(1000) .. can right values of i , i.e: i=0, i=1, i=2, i=3, i=4 using closure e.g: for (var = 0; < 5; i++) $(document.body).queue(returnfromqueue(i)).delay(1000); function returnfromqueue(i) { return function () { alert('i=' + i); $(this).dequeue(); } }

how perform periodic actions under mod_perl, apache2? for instance, need reload data remote location, process it, , store in memory. ideally, don't want while request being served. i highly doubt alarm never used across our codebase, setting periodic alarm won't work. external storage (like redis/memcached) can fast still not fast process's own memory. i believe can done using custom signal, pkill , cron. signal handler execution may postponed until cleanup phase if needed. but maybe there's more straightforward way? obvious don't see? if built perl embedded apache threading support, create thread in startup script. if not, it's going complicated make sure every apache process updates itself.

hi every java developper, have juste simple question jvm, want know how long jvm wait thread ? example, take @ code : public static void main(string[] args) { p = runtime.getruntime().exec("myshellcommand -p1 v1 -p2 v2"); p.waitfor(); system.out.println("end ....:)"); } suppose "myshellcommand" running ever, whats happen ? jvm still waiting ever ? the waitfor method causes current thread wait, if necessary, until process represented process object has terminated. method returns if subprocess has terminated. if subprocess has not yet terminated, calling thread will blocked until subprocess exits .(from javadoc ). based on documentation, think run forever.

we have php application needs connect soap web service—here's wsdl: https://arixss.arifleet.com/qa/driveawayws/driveawaysrvc.svc?wsdl the vendor claims uses "ws-security (wshttpbinding)". doesn't mean me, don't have experience beyond "normal" unauthenticated soap. furthermore, understand there several ways implement ws-security, , vendor hasn't provided full specification. so far, wssoap class given in this answer , have been able connect, authenticate, , run getallrequests method successfully. however, i'm stuck when trying run getrequestdetail method, because don't know kind of parameter argument use. vendor offers snippet of .net code example: driveawayclient client = new driveawayclient(); client.clientcredentials.username.username = "…"; client.clientcredentials.username.password = "…"; arirqst rqst = new arirqst(); rqst.rqsttype = "order"; rqst.orderid = "12345"; string requestdetail; ...

okay have 3 tables; enduserdevicemap,enduser, , device. i'm inserting enduserdevicemap need information both enduser table , device table. insert enduserdevicemap (fkenduser,fkdevice,defaultprofile,tkuserassociation) select enduser.pkid,device.pkid enduser,device enduser.userid = 1001, device.name '%6%' values (enduser.pkid,device.pkid,'f','1') i need device.pkid , enduser.pkid keep getting syntax error. know wrong in many ways... first number of attributes insert should matching number of attributes of select. second, don't need last values line third, sure not missing relation between tables: enduser , device, because insert possibilities. example, (it might not make sense choice of attributes example of how use insert table): insert enduserdevicemap (fkenduser,fkdevice,defaultprofile,tkuserassociation) select e.fkenduser,e.fkdevice,d.defaultprofile,d.tkuserassociation enduser e,device d enduser.userid = 1001 , device.n...

for reason when run file answer seems 0. i'm still new java explain me i've done wrong.. seems fine me. public class bus { public static void main(string[] args) { bus fivepm = new bus(23, 120); bus elevenam = new bus(27, 140); system.out.println(fivepm.gallonsused()); system.out.println(elevenam.gallonsused()); } private int mpg; private int milestravelled; private double used; public bus(int mpg, int milestravelled){ this.mpg = mpg; this.milestravelled = milestravelled; } public double gallonsused(){ this.used = this.mpg/this.milestravelled; return this.used; } } in both of instantiated bus objects, milestravelled less mpg. when divide int int, int. this.mpg/this.milestravelled; this return 0 because digits after decimal point don't matter if it's int. to make them not ints, things like: this.mpg * 1.0 / this.milestravelled or this.mpg/((double) this.milestravelled)

i have list: [(hello(21,15),'now')] tuple inside list, , want extract tuple way output (hello(21,15,'now') just do: lst[0] to first element since list indices start @ 0 examples >>> = [1,2,3] >>> a[0] 1 >>> a[2] 3 your case >>> = [(hello(21,15),'now')] >>> a[0] (hello(21,15), 'now') if further want 'now' text do: >>> a[0][1] 'now' extension if want range of values list, can use [:] follows: >>> = [1,2,3,4,5,6,7,8] >>> a[2:6] #this gets elements index 2 5 [3,4,5,6] >>> a[-1] #this gets last element of list 8
