perhaps simple or stupid question. have tested 3 separate apps, each simple uitableviewcontroller apps detail view controllers pushed onto stack. work no problems. i've decided build new app uses 3 tab uitabbar controller rootviewcontroller , have these 3 separate tableviewcontrollers running off tabbar controller. can fire first level tableviews can't push respective childviewcontrollers onto stack. i'm using same class code each uitableviewcontroller in tabbar app tested in tableview app. am missing obvious here? why wouldn't work because of tabbar controller? thanks insights in advance. if closer @ 3 separate apps, you'll see have uitableviewcontrollers inside of uinavigationcontrollers. left navigation controllers out of version uitabbarcontroller. the hierarchy should this: uitabbarcontroller ┣ uinavigationcontroller ┃ ┗ uitableviewcontroller ┣ uinavigationcontroller ┃ ┗ uitableviewcontroller ┗ uinavigationcontroller ┗ uitablev...

i'm still novice @ php appreciated. i'm using custom menu display 4 posts, , each post i'd post thumbnail. code below, gives me invalid argument supplied error. <div id="stampnav"> <?php $pages = wp_nav_menu( array( 'container_class' => 'menu-header','theme_location' => 'stamp-menu' ) ); foreach($pages $pagg) { echo get_the_post_thumbnail($pagg->id, 'thumbnail'); } ?> </div> you need call global $post , make query post thumbnail menu not return meta associated page, queries built in "menu" custom post type. your other option create custom walker class nav menu.

i trying turn query result classes. $result->setfetchmode(pdo::fetch_class, 'myclass', array()); this works quite class name myclass depends on column values. is possible fetch each row , turn different class depending on rows values? user example: id # name # age 1 # jon # 12 2 # sue # 23 3 # tom # 24 i want have users age less 21 instances of class child . rows age of 21 , above should instances of class adult . so "jon" should instance of child . "sue" , "tom" should instances of adult . as not know type (classname) of returned objects before query, can not specify it. however, encapsulate logic inside type use return type can return specific return type: /** * should not have private, public or protected members in it's definition. * * work public properties. */ class returnobject { public function getconcrete() { /* decide here class */ $classname = 'child'; // ...

refering c++11 specification (5.1.2.13): a lambda-expression appearing in default argument shall not implicitly or explicitly capture entity. [ example: void f2() { int = 1; void g1(int = ([i]{ return i; })()); // ill-formed void g2(int = ([i]{ return 0; })()); // ill-formed void g3(int = ([=]{ return i; })()); // ill-formed void g4(int = ([=]{ return 0; })()); // ok void g5(int = ([]{ return sizeof i; })()); // ok } —end example ] however, can use lambda-expression default value function argument? e.g. template<typename functor> void foo(functor const& f = [](int x){ return x; }) { } yes. in respect lambda expressions no different other expressions (like, say, 0 ). note deduction not used defaulted parameters. in other words, if declare template<typename t> void foo(t = 0); then foo(0); call foo<int> foo() ill-formed. you'd need call foo<int>() explicitly. since in case you're u...

i have csv file 2 records. when try upload file through magento upload module it's uploading more 196 records. crossed check in file 2 records there. what's problem? it's related cache or index something?? reference attached screenshot of page also. you have records stuck in dataflow_batch_import reimporting. it's common problem have stuff stuck in dataflow_batch_(import|export) , nexcess has nice cleanout tool here. dataflow batch table cleanout you can monitor various log tables bloat , @ dataflow table contents script see if have stuck items before doing import. log table monitor dataflow import keeps each import file you've uploaded (var/import littered these unless manually delete them). make sure choosing latest file you've uploaded when go run profile. numbers @ front of file names in dropdown list date/time stamps.

i want dig deeper django's internals , official online documentation goes far toward end. the reviews marty alchin's pro django fantastic (i've read pro python , enjoyed it). however, book 2008 , based on django v1.0. company builds off v1.3. is book still worthwhile? how can best learn django's meta-programming (beyond looking through source code, doing)? thanks yes, it's still relevant. although lot has changed in django since version 1, internal parts , concepts pro django deals same. i'd have no hesitation in recommending book - it's useful insight how django works , teaches useful methods well.

i read data webview.db database created when app uses webview. however, database managed classes package level or not provide in way of access through apis. since can't share database objects or locks, how can safely read content database without getting "database locked" errors or similar exceptions? i need read, not need write. if there no way safely aquire sql queries/cursors on it, there way safely copy actual webview.db file in thread safe manner? there danger of getting corrupt copy? thanks much i think locks @ sqlite level, not in java code, should able away opening db , reading without confusing webview. however, same reason should prepared lock errors , retry queries until lock gone. db locked when webview data altering statements. webview doesn't put exclusive lock on db whole time it's running, don't see reason that.

i have java project dependent on other java projects siblings , there chain of dependencies. each individual project has build script written in ant. clarity find below sample of same. earproject depends on webproject , ejbproject : war file generated webproject build , jar file generated ejbproject needed build earproject . webproject depends on componentoneproject : jar file generated componentoneproject build needed build webproject . ejbproject depends on componenttwoproject : jar file generated componenttwoproject build needed build ejbproject . so, when build earproject build, if dependent war , jar have not been built yet, should kick-off webproject build , ejbproject build , if componentoneproject yet built, build of componentoneproject needs kicked-off , on. can suggest clean method can accomplish this? facing same problem @ our company wrote custom groovy script explores full dependency tree ant generates ant build scripts based on .p...

i calling third party com object asp.net invoke executable follows b = new mybw.baan4class(); at given time there muliple instances invoked asp processes. how can pid of b can 'kill' without disturbing(killing) others.. without knowing more details com object using don't think there's great way associate exe launches , object creating. with said delegate responsibility of creating these objects centralized location (wcf service running in singleinstance mode maybe) can associate object created exe instantiating new object , waiting exe launched. when exe has been launched can associate object created exe launched. use wmi detect when new exe has been launched. it's going pretty impossible in asp.net since multiple users instantiating these objects @ same time. running race conditions if tried here. here similar question: how determine association between vb6 app , exe instanced createobject()
