symfony - MongoDB With Symfony2 -


i have make auto suggest on city level have list cities of mapped respective countries usa => ( "new york", "dallas", "los angeles" .....)

what need save in mongodb symfony2 mapping method. searched lot not able find proper or documentation regarding array handling in mongodb.

please explain if has experience in area.

namespace sptl\userbundle\document;  use doctrine\odm\mongodb\mapping\annotations mongodb;  /** * @mongodb\document */ class city { /**  * @mongodb\id  */ protected $id;  /**  * @mongodb\string  */ protected $country;  /**  * @mongodb\hash  */ protected $city = array();   /**  * id  *  * @return id $id  */ public function getid() {     return $this->id; }  /**  * set country  *  * @param string $country  * @return \city  */ public function setcountry($country) {     $this->country = $country;     return $this; }  /**  * country  *  * @return string $country  */ public function getcountry() {     return $this->country; }  /**  * set city  *  * @param hash $city  * @return \city  */ public function setcity($city) {     $this->city = $city;     return $this; }  /**  * city  *  * @return hash $city  */ public function getcity() {     return $this->city; }

}

usage insert:

    $dm = $this->get('doctrine_mongodb')->getmanager();     $cities = new city();     $cities->setcountry("usa");     $cities->setcity(array("new york", "dallas", "los angeles"));     $dm->persist($cities);     $dm->flush();

inserted record:

{  "_id": objectid("5252b03f6b0f57394e2fb1b5"),  "country": "usa",  "city": {   "0": "new york",   "1": "dallas",   "2": "los angeles"     }  }

code used retrieve:

$repository = $this->get('doctrine_mongodb')->getmanager()     ->getrepository('userbundle:city'); $cities = $repository->findby(array("_id"=>'5252b03f6b0f57394e2fb1b5')); print_r($cities);

but not able record above retrieval code.....

if need retrieve city id of type objectid must create object mongoid , give id string

example:

    $repository = $this->get('doctrine_mongodb')->getmanager()         ->getrepository('userbundle:city');      $cityid = new \mongoid("5252b03f6b0f57394e2fb1b5");     $city = $repository->find($cityid);      var_dump($city);

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
