i have string contains numbers this: 2243. need total of these numbers. using example numbers in string converted integers , i'd able this: 2+2+4+3 = 11. not having coded in quite while find myself bit stumped on (probably) quite easy task. all appreciated! you can : var number:string = "2243"; // represents original string number var result:int = 0; (var i:int = 0; < number.length; i++) { result += parseint(number.charat(i), 10); } // result var contain sum

i need mysql query return " value " , " label " field name. i have " value " id of user , " label " " name lastname " or "*name_first_letter lastname*" directly query. lets have table this: id name lastname 1 john johhanson 2 peter petterson 3 jeff jefferson i id "value" simple query: select id value . "j. johhanson" or "p. petterson" " label ". update sorry bothering. tried concat , concat_ws . unsuccessfully, managed results easily. in case query worked needed: select concat_ws(' ', name, lastname ) users name "%peter%" thank you. select id value, concat(left(name, 1), '.

i have main cmake project has project_include_path cached variable. pass variable cmake_args parameter external project add using externalproject_add(). the problem is, when change value of project_include_path using 'make edit_cache' external project not reconfigured. is there way make external project reconfigured , built automatically when cached variable changed in main project? i re-run cmake after modifying cmakecache.txt (not often). update externalproject_add call in case. probably safer option here avoid make edit_cache , , re-run cmake command line parameter of -dproject_include_path:path=<updated value> .

jit method optimization (-xx:+printcompilation) after 10k invocations , can configure -xx:compilethreshold. read reason not lower threshold jit optimization might wrong or optimize infrequently used code. have few questions regarding area: i think wrong optimization (ie: on-stack-replacement) due lazy classloading of polymorphic methods. after 3 implementations (i think) found, jvm index table lookup. of course, speed suffers if have more polymorphic impl. polymorphic method cause or major cause wrong jit optimization? if not, others? what if force loading classes @ astartup jvm can build such index tables upfront, isn't better overall optimization upfront? what's wrong optimize-all approach? what's cost if goal speed? comparing c++, if source closed means no 3rd party lib, low-latency system, there way force optimization upfront increase performance closer of c++? peter lawrey mentioned in oracle magazine article can kick-in jit artificially run enough test data ...

i want use lambada expression search status equals 1 or 2. code following: return database.find<patient>(p=>(p.id==id && p.status ==1)||(p.id==id && p.status==2)); i know it's not right, understand want above code. i use c# update: sorry guys, realize not reason of syntax, it's reason of third party api use data db. please close question. return database.find<patient>(p=>p.id==id && (p.status ==1 || p.status==2));

i want start address of thread using it's id. possible? well, not trivial following reason: in win32 subsystem all threads have same start address. in windows (but not including) vista inside kernel32.dll (named basethreadstartthunk according official symbols). in windows versions starting vista, common start address rtluserthreadstart in ntdll.dll (and basethreadstartthunk got renamed basethreadinitthunk , seemingly win32-specific tasks now). however, attempt suspend thread, retrieve context (using getthreadcontext ) , traverse stack top investigate parameters there. require reverse-engineering of each implementation of kernel32.dll thread start routine, should doable. an alternative use undocumented native api ntqueryinformationthread threadquerysetwin32startaddress . there an msdn page function, far complete.

i have following field type (notice no filters, no tokenizers) <fieldtype name="text_names" class="solr.strfield" /> i create field in schema using type: <field name="exact_type" type="text_names" indexed="true" stored="true" /> now, search q=*:*&fq=exact_type:aa&fl=exact_type still results have other 'aa' in exact_type field. missing here? also behaves same: q=exact_type:aa&fl=exact_type i don't think "q=*:*" works dismaxhandler , believe using ,the correct syntax both queries should be: q=&fq=exact_type:aa&fl=exact_type fq=exact_type:aa&fl=exact_type

i'm looking best way prevent accidental deletion - perhaps copying disk or separate azure storage account or amazon. tools can this? redgate cloud services seems closest fit want seems require config per container. know of other tools cloud storage studio , azure sync tool exist don't think support scheduled backups of blob storage. windows azure storage backed geo-replication means there total 6 copies of data @ given time. there no built-in service available in windows azure backup data on azure storage outside azure storage or user defined location. windows azure azure manged restful interface 3rd party vendors have created application such purposes. besides above had chance use gladinet cloud backup solution useful in case. based on experience, there few backup tools available , not single 1 perfect match expectation.

is there way setup mybatis springmvc have 1 transaction whole http request? there hibernate opensessioninviewfilter in mybatis or should write own filter fulfill such behavior? you confused notions "session" , "transaction". osiv opens session, in 1 session several transactions may coexist. should put @transactional attributes services used controllers, depending on business requirements. moreover, 1 big transaction anti-pattern. ideally have read-write transaction user's actions, , read-only transaction build response user. saves resources, because database locks taken inserts/updates released earlier.

while debugging in visual studio 2010, there way view keys of httpsessionstate in quickwatch window? there must better method exiting debugging session, coding loop on session.contents.keys object, breakpointing , stepping through loop - see keys defined. i suspect i'm going in entirely incorrect manner. , hints or advice appreciated. httpsessionstate ienumerable , long system.core dll loaded in process you're debugging, can evaluate system.linq.enumerable.toarray(system.linq.enumerable.cast<object>(myhttpsessionstate)) in quickwatch window. if current code file has using system.linq statement, can write shorter expression: myhttpsessionstate.cast<object>().toarray() if you're having @ httpsessionstate objects often, may want try bugaid , , define above expression custom expression on httpsessionstate class, won't forced type in long expression each , every time. full disclosure: i'm co-creator of bugaid.

what mysql both insert ignore , … on duplicate key update ? this not question differences . ask because talend etl behind ui , i'm worried have side effects if don't want update , this: string insertignore_tmysqloutput_10 = "insert ignore `" + "employees" + "` (`name`,`jobtitle`) values (?,?) on duplicate key update `name` = ?"; ignore acts kind of error-suppressor, making fatal errors act warnings instead. on duplicate key update doesn't trigger error, ingore has no effect on it. therefore, ignore has no effect on duplicate keys when on duplicate key update used well. however , if different error occur ignore indeed have effect.
