(done) then create store. the question answer - how parent certificate or certificates in chain using windows certificate store? i'm missing more or less occult function here. as certfindcertificateinstore outputs chain context, 1 can access it's members using beautiful construction: chaincontext->rgpchain[0]->rgpelement[icertindex]->pcertcontext->...

i m trying understand 1 in terms of how compares other. is grey box testing can see code , black box testing don't @ code? black box testing when know nothing system. know input , check output without knowing process in between input , output. grey box testing same know things internals of system. example have knowledge architecture or have implementation documents. mix of white (see further) , black box testing (it's in between). white box testing when know system. source code, architecture. test program completely, check if doing expected, check exceptions or errors. have understand how code works. so answer question, both black box , grey box testing don't check code. in grey box testing it's more internal structure , architecture have knowledge, in algorithms used. you can find info on wikipedia or this url explains white, grey , black box testing.

i working on image processing scripts in .net , came across following article outlining how crop, resize, compress, etc. in first comment , states methods used in article imaging notorious memory leaks: a quick warning thinking using system.drawing (or gdi+) in asp.net environment. it's not supported microsoft , msdn (as of recently) states may experience memory leaks. then, in second comment, article author says "i've handled problem": just make clear code above isn't thrown together. evolved time because suggested easy mistakenly create performance issues when using gdi+. just see how many times i've written 'using' above! i wondering how (or if) use of using handles (or improves) memory leak problems referenced in first comment. the using statements don't anything performance wise. calling dispose method on objects using declared on. calling dispose allow unmanaged resources, gdi+ creates imag...

i tried insert 4000 contacts using google create contact api client library using batch request. google returned 4000 google contact ids. when try fetch contacts using contact ids, observed around 1000 contacts inserted , remaining empty contacts. cross checked in google contacts ui , via api also. reasons problem. samplecode: batchutils.setbatchid(newentry, "create"); batchutils.setbatchoperationtype(newentry, batchoperationtype.insert); requestfeed.getentries().add(newentry); //requestfeed contactfeed , newentry contactentry posturl=new url("https://www.google.com/m8/feeds/contacts/default/full/batch?xoauth_requestor_id=" + loginuser); contactfeed responsefeed =conservice.batch(posturl,requestfeed);

i have following computed column within create table function: create table test ( code1 nchar(10), code2 nchar (10), type nchar(10), final case when len(code1)>0 code1 when len(code2)>0 code2 else type end ); alter table test add constraint pk_test1 primary key (final) but getting following error "cannot define primary key constraint on nullable column in table". this because code 1, code 2 , type can null, 3 never null. 1 of them have value. is there anyway can define computed column primary key above in mind? many - jt your computed column needs persisted , not null used primary key; create table test ( code1 nchar(10), code2 nchar (10), type nchar(10), final case when len(code1)>0 code1 when len(code2)>0 code2 else type end persisted not null ); an sqlfiddle test with .

i want generate bunch of lists using combinations of elements specified in form following: [[10, 20], [30, 40], [50, 60]] this means values available first element 10 , 20, values available second element 30 , 40 , on (i've used 2 element options each element brevity; there more that). want use specification generate lists using combinations of these elements (including possibility of not having any), generating following: [10] [20] [10, 30] [10, 40] [20, 30] [20, 40] [10, 30, 50] [10, 30, 60] [10, 40, 50] [10, 40, 60] [20, 30, 50] [20, 30, 60] [20, 40, 50] [20, 40, 60] i feel though itertools used this, i'm not sure how implement algorithm generate lists this. good, general way (i.e. not limited 3 elements 3 hardcoded nested loops, instance) generate lists specification i've shown above? as attempt, i've got following: import itertools element_specifications = [[10, 20], [30, 40], [50, 60]] lists = [list(list_configuration) list_configuration in list...

so i've read thing called solid (mixed with) writing testable code . , d part. how 1 follow these guidelines when using primitive types or methods/classes provided language library. does 1 need use dependency injection arrays (java ( new int[64] ) or class members of say, filewriter?. these need injected using di or can class still instantiate them? how far should go following above guidelines? i not looking language-specific answer (if possible). imho answer should apply to, ex, php, python java, heck, c you don't inject primitives or dto / pojo -like objects. reason are: simple value holders without business/domain logic associated easily stubbed without tools (creating array of fake data test not problematic) filewriter different it's in exact opposition points above. can't stub in test , make work without few strong assumptions - like, assume every future developer running code have file on machine. no-go unit tests , 1 of reasons why ...
