i want following error: implicit conversion type char[] string not possible. string pattern2 = (convert.todatetime(currmail.creationtime).tostring(" dd-mmm-yyyy hh-mm")).toarray(); does have idea on how deal this? remove .toarray() : string pattern2 = convert.todatetime(currmail.creationtime).tostring("dd-mmm-yyyy hh-mm");

suppose have set of entities: $entities = $em->getrepository('mybundle:entity')->findby(array('cat' => 1)); what best way pick single entity out of set id? of course can search loop or array_filter , e.g.: $entity = null; foreach ($entities $_entity) { if ($_entity->getid() == $id) { $entity = $_entity; break; } } but maybe there build in symfony/doctrine method that? hi can use filter method arraycollection class, it's not different looping entities you're doing $idtosearch = $n; $newcollection = $entities->filter( function($entity) use ($idtosearch) { return $entity->getid() == $idtosearch; } );

i trying method of interface explained here in this tutorial: here go: databasemetadata dm = con.getmetadata(); system.err.println(dm.supportsresultsettype(resultset.type_scroll_sensitive)); i know supports type_scroll_sensitive type. using , works. method above reported returns false. have ever tried using method? if yes work properly? in advance. ps: same happens other 2 types of resultsets ( type_scroll_insensitive , type_forward_only ). considering type_forward_only default type it's little bit strange false in 3 cases. update: using jdbc-mysql drivers; the implementation in mysql connector/j 5.1.21 is: public boolean supportsresultsettype(int type) throws sqlexception { return (type == resultset.type_scroll_insensitive); } however quick @ rest of implementation suggests mysql supports other types.

currently doing exams , i'm struggling through concepts. these have been 'mentioned' in notes didn't understand how linked together. far understanding is: soa - solution make service consumers/providers communicate. (as far understand umbrella term else) wsdl - language describes provider service. soap - xml protocol 'wrapper' used services send messages. works in conjunction wsdl provide parameters? rest - design pattern similar soap in function avoids xml? (really not sure one) json - alternative xml uses javascript? (not sure 1 either) looking around in internet there doesn't seem clear definition of of these , how interlink. imagine developing web-application , decide decouple functionality presentation of application, because affords greater freedom. you create api , let others implement own front-ends on well. did here implement soa methodology, i.e. using web-services. web services make functional building-blocks acces

i built number of wcf services part of application. until recently, of classes used parameters of many operations in service did not had datacontract or datamember attributes applied them. now, i've made few changes in row , of sudden wcf complaining can't serialize classes. does knows if changes in configuration or in servicecontract, operationcontract etc. can cause wcf become picky classes can serialize? i'd rather not need attributes in classes (they should pure c# classes possible). also of note, if return previous version in source control, wcf goes "normal", believe it's not machine/environment thing. the ability create wcf data contracts without use of [datacontract] , [datamember] attributes feature added wcf in .net 3.5 sp1. since works when reverting code previous version, i'm assuming using @ least version. nevertheless, in order classes serializable wcf, class must meet several requirements listed here . main requirem

i have php script reads contents of xml file , creates object using $xml = new simplexmlelement($file_name, 0, true); it converts object workable array , loops through array , saves data database. i've noticed when using script on , on again, thought xml files same size script takes longer , longer. do need free memory, or there practices can when i've reached end of memory intensive script? first thing i'd check database structure. might need drop/add indexes in database tables. stuff slowing down because database slowing down, exposing weak spots in database. you need metric script. echo out time before , after database queries. check how time spent individually , in total , how on lines containing queries. so @ beginning , end of script , before , after query lines , do: echo microtime(), "<br />\n"; if not problem (and surprise me), can check if perhaps storing data (for example) session or so.

when using grep command find search string in set of files, there way dump results text file? there switch grep command provides cleaner results better readability, such line feed between each entry? perhaps there grep script outputs cleaner results thanks grep -n "your search string" * > output-file the -n print line number , > redirect grep-results output-file. if want "clean" results can filter them using pipe | example: grep -n "test" * | grep -v "mytest" > output-file match lines have string "test" except lines match string "mytest" (that's switch -v ) - , redirect result output file. a few grep-tips can found on post

i trying summarise data tables report. each record in table consists of date range, this: startdate enddate -------------------- 13/04/13 15/04/13 17/04/13 24/04/13 28/04/13 03/05/13 05/05/13 10/05/13 assuming date ranges signify days of leave, want able calculate total amount of days of leave per month. came across datepart function seems work apart 1 edge case: when date range crosses month boundary. since datepart function returns month 1 given date, no longer able use determine amount of days of leave edge case record (in example above record 3), since applies 2 separate months. ideally want final table like: month #ofdays -------------------- 4 11 (1st record - 2, 2nd record - 7, 3rd record - 2) 5 8 (3rd record - 3, 4th record - 5) i've considered messy options, such populating temporary table having each record signifying different day , doing query on that, not sure how ties in rep
