let's i've got custom post type order , custom field order number , , let's these custom posts created on form submission. what need increment order number field automatically in safe way, numbers aren't duplicated. the trivial solution: on form submission, find last order , use number + 1. in case when 2 users submit form @ same time, same order number. i doing such things custom frameworks in past: lock db row update, increment number, release. safely increment number. require creating separate table counter , i'd prefer avoid that. i didn't find ready in wp api. i'm using wp 3.8 on mysql. auto-increment functionality implemented long time ago in mysql, have specify id of table auto_increment . however, if insert data on form submission , create custom post type, inserting data in wp_posts table, done there, because table, posts stored in wordpress , already have id set auto_increment .

i using unreal engine 4 , seems can't avoid casts. acontroller* c = this->getcontroller(); aplayercontroller* p = (aplayercontroller*)c; is there way can check if c playercontroller before cast? like lot of game engines, unreal engine compiled without rtti performance reasons, dynamic_cast not work. unreal engine provides own alternative, called cast . can't find documentation right now, this question describes use nicely. acontroller* c = this->getcontroller(); aplayercontroller* p = cast<aplayercontroller>(c); if (p) { ... } acontroller has convenience method casttoplayercontroller same thing: acontroller* c = this->getcontroller(); aplayercontroller* p = c->casttoplayercontroller(); if (p) { ... } if sure c going aplayercontroller castchecked more efficient: acontroller* c = this->getcontroller(); aplayercontroller* p = castchecked<aplayercontroller>(c); ... in debug builds, use cast , throw assert i...

i using tesseract ocr extract text image. preserving structure of document important me. tesseract not preserve structure, infact changes order of text. input image below. and output getting follows: someto left someto left in middle in middle some tab some tab some space between them some space between them sometext here sometext here this how desired output of same structure in image? i.e. follows: text here text here left left in middle in middle some tab some tab some space between them some space between them newer versions of tesseract (3.04) have option called preserve_interword_spaces should want. note number of spaces tesseract detects between words may not same between similar lines. words left-aligned run of spaces preceding them (as in examp...

this question has answer here: checking objective-c block type? 5 answers i have array of dictionaries, stores blocks , queues. after method need execute it. for (nsdictionary * dict in self.arrayofblocksandqueues) { if (!dict[@"block"] || !dict[@"queue"]) { continue; } dispatch_block_t block = dict[@"block"]; dispatch_async(dict[@"queue"], ^{ block(); }); } so question is, how can check in runtime, dict[@"block"] , dict[@"queue"] type i’m expected? have typedef void(^handler)(); , need sure dict[@"block”] type of handler . know, blocks , queues in fact objective-c objects, don’t conforms <nsobject> protocol. so, there anyway it? thanks in advance! you can create class block/queue property easy manipulation. try setting block , queue properie...

i have independent project writing test cases; problem can't mock httpservletrequest , because in servlet there calls getservletcontext() test cases running outside servlet container. return error saying "no context found". 1 dependency servlet container; there can hundreds. example, initialcontext.lookup() depends on container. how can use mockito write test case in scenario? please don't ask error message; it's more of logical problem technical. looking on internet tutorials makes me wonder if doing wrong. no 1 seems have encountered problem before... how can mock httpservletrequest without ever having getservletcontext() called in servlet? mean seriously, how rare can be? you have servlet implementation uses servletcontext , e.g. public class someservlet extends httpservlet{ protected void doget(httpservletrequest req, httpservletresponse resp) throws servletexception, ioexception { servletcontext servletcontext = getservletc...

i'm new c++ , need use set stl i'm struggling concept. i have array int my_data[3] i want create (don't know if possible) set space 3 ints , key set int stored on first column. i want make custom sort. this i've tried no success. struct sort_set { bool operator() (const int& a, const int& b) const { int* arr1 = (int*) a; int* arr2 = (int*) b; int diff = arr2[1] - arr1[1]; if (diff) { return true; } else if (diff == 0) { int diff2 = arr2[2] - arr1[2]; if (diff2) { return false; } } return arr1[0] < arr2[0]; } }; set<int[3],sort_set> data; can point me in right direction? you cannot have arrays elements of containers. they're not assignable nor copyable. use std::array<int, 3> if have c++11 avaliable, or define custom class otherwise.

i assume when doing look-up in dictionary needs hash key giving , use hash find object looking for. if so, using larger objects keys slow down look-up or have other consequences not encountered using string or simple data type key? yes, it's bad idea use mutable object dictionary key. taking @ https://stackoverflow.com/a/7941876/400760 , leads me believe there unintended consequences, correctly implemented gethashcode() based on how hash based collections typically implemented. it should safe use immutable object dictionary key.
