hi methods like '- (nsfetchedresultscontroller *)fetchedresultscontroller ' are placed in code of view controllers. find bit messy write data fetching code along lifecycle methods or table delegate methods. point should refactor coredata methods other helper class dataloader , call them in view controllers? wrong thing or going loose coding benefits of core data methods. i moving fetchedresultscontroller helper class idea. problem encounter spelling of attributes right. for example predicate , want filter on attribute called @"isselected" . there no check compiler nor linker check string isselected . have double check each line string has been used. a search&replace won't work on misspellings because don't know bugs have been introduced. when predicate wrong no results fetched. problem don't know if there no matching rows or if have filtered wrong. need check @ runtime , consumes time. for predicates saved templates exist, p...

how can configure zend_controller_router use default route default? whatever reason unknown, uses current route. this causing annoying routing issues, , don't feel editing hundreds of links explicitly use default route reasonable solution add 1 custom route. your question isn't obvious , confusing, try though. i going assume not mean zend_controller_route in fact talking links generated in views. you can use baseurl() this <a href="<?=$this->baseurl("about-us")?>">about us</a> you can set baseurl in bootstrap this zend_controller_front::getinstance()->setbaseurl("/"); if working locally may want set this zend_controller_front::getinstance()->setbaseurl("/my-app/public"); using baseurl() in views use path base urls on. remember must wrap links in baseurl() work. the url() helper not useful this, used doing things pagination want current parameters of request object maintaine...

i heard way create branch in mercurial repository make changes in working copy, commit them new branch. in subversion, can create branch without having make changes (by copying trunk path under tags ) - possible in mercurial well? i've seen tortoisehg, it's possible can done via command-line tool , don't know it. my workflow is: create feature branch. do work in feature branch. create release candidate branch. merge feature(s) release candidate branch. deploy, test, fix deploy, test, fix release candidate branch. merge release candidate branch trunk. many in advance. it depends on mean branch. a named branch can created giving name , committing, it'll end new changeset in history, don't need explicitly change of files in working folder allowed commit. hg branch newname hg commit -m "created branch newname" you can using tortoisehg dialog. however, if want create unnamed branch, ie. head, yes, need change something. , ...

i have problem hibernate mapping , queries. have object have relation b , c. the fetch mode lazy ( @manytoone(fetch = fetchtype.lazy) ) , can't change it. problem next: when object method ( hibernatedao.get ), object whitout relation b , c. if create criteria, force relation criteria.setfetchmode(...) query. have read on web it's not thing make criteria object primary key. how method ? thanks. you can use fetch profiles have fetch mode set lazy default, , eager specific query: http://docs.jboss.org/hibernate/stable/annotations/reference/en/html_single/#d0e3524 and if using hibernate version doesn't supports fetch profiles, can hql query retrieves tree need, using joins. but have read on web it's not thing make criteria object primary key. i careful before ruling out solution because read somewhere it's "bad". may bad thing in end, if don't understand why bad, may ruling out solution made specific case ;-)

there patterns checking whether parameter method has been given null value. first, classic one. common in self-made code , obvious understand. public void method1(string arg) { if (arg == null) { throw new nullpointerexception("arg"); } } second, can use existing framework. code looks little nicer because occupies single line. downside potentially calls method, might make code run little slower, depending on compiler. public void method2(string arg) { assert.notnull(arg, "arg"); } third, can try call method without side effects on object. may odd @ first, has fewer tokens above versions. public void method3(string arg) { arg.getclass(); } i haven't seen third pattern in wide use, , feels if had invented myself. shortness, , because compiler has chance of optimizing away or converting single machine instruction. compile code line number information, if nullpointerexception thrown, can trace exact variable, since have 1 such check ...

bear me here. a couple months ago remember algorithms teacher discussing implementation of bucket sort (named distribution sort in algorithms book) , how works. basically, instead of taking number @ face value, start comparing binary representation so: // 32 bit integers. input: 9 4 4: 00000000 00000000 00000000 00000110 9: 00000000 00000000 00000000 00001001 // etc. and start comparing right left. // first step. 4: 0 9: 1 output: 9 4 // second step 4: 1 9: 0 output: 4 9 // technically stable algorithm, cannot observe here. // third step 4: 1 9: 0 output: 4 9 // fourth step 4: 0 9: 1 output: 9 4 and that's it; other 28 iterations zeroes, output won't change anymore. now, comparing whole bunch of strings go // strings input: "christian" "denis" christian: c h r s t n denis: d e n s // first step. christian: n denis: s output: christian, denis // second step christian: denis: output: denis, christian // ... and f...

first of all, here's concept art how custom list control must look: http://img816.imageshack.us/img816/1088/customlistctrl.png each list item complex , turns "edit interface" when mouse hovers on it. have png image files every skinning detail of thing, including scroll bar. what best approach started implementing this? create custom control , render of in gdi ? could make list control transparent clip region scroll bar? individual list items, use textured panel backdrop each item , place existing .net forms (like combo boxes, buttons, edit fields, etc) children of that? i've never had create detailed before. if want control exactly given picture (which nice), end drawing of it, if not of it, yourself. 1 possibility subclass each control being used , override onpaint method custom drawing. assumes design in picture individual control. i myself might make each row separate usercontrol -derived class, perhaps internal constructor users of contr...
