i develop android application using html,css , javascript in android sdk. dont want use tool titanium , phone gap . is possible make application using html,css , javascript ? are android web apps native apps? can same functionality achieved through web apps? if in comparison of native application , can 1 tell me proper way or provide me tutorial ? the short answer: yes, can develop apps using html / css / javascript. take 2 webview tutorials , call me in morning. the long answer: if want write apps android use html / css / javascript, you'll have @ least create native webview wrapper. relatively easy -- unless want hook native functions, such accelerometer, camera, or toast messages (the little messages pop when happens). accessing native hardware , software through webview requires write javascriptadapter (available in android 2+), , define custom javascript methods in javascriptadapter. methods map java function, have access native os facilities. fram...

i have table has header checkbox in row. data gets dynamically added in table javascript. checking on checkbox in header row checks or unchecks checkboxes of rows.. have done till here in method "checkuncheck()" , i.e.: <input type="checkbox" id="chkappid" onclick="checkuncheck()"/> but now, suppose there 10 records dynamically added in table. have checked main checkbox in header. after that, uncheck 1 of checkboxes, e.g.: on 10th row, checkbox of header must unchecked....and if check of 10 rows of checkboxes manually, checkbox of main header must checked. observed in yahoo, gmail, etc... one way count number of checked ones , compare total number of rows, , if found equal, check main one; otherwise, uncheck main one. can't figure out that... not working! update <html> <head><title>checkbox puzzle</title></head> <body> <input type="checkbox" id="chkappid" oncl...

i've implemented number of genetic algorithms solve variety of problems. i'm still skeptical of usefulness of crossover/recombination. i first implement mutation before implementing crossover. , after implement crossover, don't typically see significant speed-up in rate @ candidate solution generated compared using mutation , introducing few random individuals in each generation ensure genetic . of course, may attributed poor choices of crossover function and/or probabilities, i'd concrete explanation/evidence why/whether or not crossover improves gas. have there been studies regarding this? i understand reasoning behind it: crossover allows strengths of 2 individuals combined 1 individual. me that's saying can mate scientist , jaguar smart , fast hybrid. edit: in mcdowella's answer, mentioned how finding case cross-over can improve upon hill-climbing multiple start points non-trivial. elaborate upon point? you correct in being skeptical cr...

i have 8 jlabels want invisible . jlabels start 25 , go 32. _(i.e jlabel25 ---> jlabel32)_ instead of making them invisible 1 one thinking of using loop make them invisible following these lines of code : for( int = 25 ; <= 32 ; i++ ) { jlabel(i).setvisible(false); } but obvious error says "cannot find symbol , method--> jlabel(int) " what should avoid writing 8 statements asking make each label invisible ? put labels common collection, , iterate through that. collection<jlabel> mylabels = new arraylist<jlabel>(); mylabels.add(jlabel25); // .. , on (jlabel label : mylabels) { label.setvisible(false); }

i'm seeing sorts of different ways handle many many relationships in yii. however, examples i'm seeing aren't fleshed out , feel i'm missing something. for instance, larry ullman's tutorial doesn't use self::many_many relation - http://www.larryullman.com/2010/08/10/handling-related-models-in-yii-forms/ so far adding , retrieving records, whats standard way handling many many in model, controller , view? clarification: suppose im looking example involving 2 tables, related many-to-many, can see not both models, controllers , views can understand whats going on. you need 3 tables (so model pivot table), once have can use regular yii relation functionality. for example project of mine has many-to-many relation between purchase , transaction (please don't ask why :) ). there purchase model, transaction model , purchasetotransaction model establishes links between them. can $opurchase->transactions , yii handle many-to-many part using r...

(and maybe i'm wrong , can still use givefeedback in scenario, not figure out how trigger event.) to eliminate possibility custom cursor not valid or corrupt, set custom cursor in mouseover event of drop target form. functionally working, wanting "pretty things up" little bit. thanks in advance insight. you seem know custom cursors set in givefeedback , how that. problem not getting givefeedback events. don't know on control have drop spot, try attaching listener underlying form's givefeedback event, , see if feedback there. you can try subclassing control using (panel, picturebox or whatever) , li...

how can improve following query think missing , can done better :( have table , one-to-many b want info , row b linked highest sequence number. came this: select a.*, ( select b.value b a.idb = b.id order b.seqnr desc limit 1 ) performance important me, best bet ? that's best bet, if visiting small number of rows , b. if going covering rows anyway, can try address problem window aggregations assigning row numbers rows b: select * ( select a.*, b.*, row_number() over(partition b.id order b.seqnr desc) seqidx join b on a.idb = b.id ) seqidx = 1 this use lot of temp space though... consider getting , b primary keys out of aggregate , joining onto them later (it's not clear query pkey columns are, since b.id apparently isn't)

i save ip numeric value in database. when fetch use virtualfield , inet_ntoa sql expression. i want ip unique, therefore use isunique validation rule in model. problem rule validates ip address against numeric value in db. is there way can modify value of field rule before validation? other rule "ip" needs ip address not numeric value. i'd suggest create custom validation rule checks if converted ip unique. … 'rule' => 'ipisunique', … // customize needed public function ipisunique($data) { return $this->isunique(array_map('ip2long', $data)); }

when in oracle 10g: select to_date(trunc(someinputdate)) table1 to_date(trunc(date_column_timestamp),'mm/dd/yyyy') >= to_date('03/11/2011' ,'mm/dd/yyyy') i get: ora-01843: not valid month if change : 'yyyy/mm/dd' , works. 'mm/dd/yyyy' valid format right? you're getting things mixed bit. to_date converts string date. if date_column_timestamp date, don't need convert date. select trunc(someinputdate) table1 trunc(date_column_timestamp) >= to_date('03/11/2011' ,'mm/dd/yyyy') the ora-01843 caused implicit conversion of date string. in other words, following: to_date(trunc(date_column_timestamp),'mm/dd/yyyy') is equivalent (assuming default date format dd-mon-yyyy ): to_date(to_char(trunc(date_column_timestamp),'dd-mon-yyyy'),'mm/dd/yyyy') so, to_char returns '11-mar-2011' , causes to_date fail because date formats not match. the same problem exists ...

i making android app, needs download text url , show on alertdialog. i created new thread. thread reads file on web, progressdialog appears before thread starts, thread packages file content web on bundle , , passes handler, handler stops progress, , shows text bundle on alertdialog. works pretty good, when screen orientation changes when progressdialog shown , thread running, app crashes. ideas on how fix thing? any appreciated. :) when orientation changes, os shut down activity , restart it. mess download thread. 1 solution might work save thread object non-configuration data. you'll need override onretainnonconfigurationinstance() in activity. however: not if thread object has references view- or activity-related object. cause huge memory leak , make users unhappy quickly. see guide topic handling runtime changes details on using onretainnonconfigurationinstance() , alternative approach. see article avoiding memory leaks on ... well, that.
