update: part of reason question traced bad database design. had allowed myself talked design in turn led poor choices ui design. decided go , refactor db design, removed problem on ui. therefore, question moot , won't accepting answer. can't delete question because there answers , comments. is there anyway cause mvc3 / ef treat empty form field zero? is, if user leaves field blank, or blanks out field, want ef treat zero, , not null value. i know how make work string fields using data annotations, can't make work integer fields. i hope question makes sense. i've been fiddling data annotations, custom validators, blah blah blah, morning , can't seem make work. this kind of work around.you can make input field 0 if empty before posting form data when user clicks submit button in form . can use javascript

i have combinations this: 1,2,3,4 //index 0 1,2,3,5 //index 1 1,2,3,6 //index 2 and on until 7,8,9,10 so n=10 k=4 combinatorics how calculate combination index for example when index==1 mycmb = func(index) returns 1,2,3,5 this example need bigest numbers, , more params , without (if possible) many loops i find obtain position: http://answers.yahoo.com/question/index?qid=20110320070039aa045ib i want reverse this... i programming in c++ sugesstions or help it seems want find k-combination given number . following example , here's should work: #include <cstddef> #include <iostream> #include <string> #include <boost/lexical_cast.hpp> #include <boost/math/special_functions/binomial.hpp> std::size_t choose(double n, double k) { using boost::math::binomial_coefficient; if (n < k) return 0; return static_cast<std::size_t>(binomial_coefficient<double>(n, k)); } // returns largest n such choos

unfortunately, c app pic32 needs oo , can't continue doing in c. do know mips32 c++ compiler pic32? thanks you might contact comeau computing ; thier c++ compiler generates c code intermediate language can utilise platform's existing native c compiler c compiler available, , therefore porting new platforms relatively quick , simple. for various reasons intermediate generation , compiler adaptation not accessible end users still need comeau generate pic32/c32 port, won't take long , amortise cost on sales other users. however if use commeau or other c++ c translator, suffer inability use source-level debugging, , likley killer attempt use c++ sucessfully without native debugger support. although not pretty, best bet learn how implement oo designs in c. here's whole book on subject: http://www.planetpdf.com/codecuts/pdfs/ooc.pdf

first off, before ask, point out question education. want know expand understanding of java , network security (what little there is). how use java network security , counter attacks? have been using server/sockets while (for non system security stuffs), don't quite understand i'm doing. naturally, should learn on networking, start? there protocol everything, heck there protocols have protocols. further expand, how use java say, port sniff, catch packets or kill/open port remotely? i guess phrase question more adequately; know of sources @ more in depth look/study of how java handles network security , counter hacking , malware containment? how use java say, port sniff, catch packets or kill/open port remotely? you can't use java sniff ports. you can't use java catch packets. you can't use java kill/open port remotely. how java handles network security , counter hacking , malware containment? java doesn't handle network

i repeatedly hear bdd enthusiasts advocate using both specflow , mspec in same project. apparently specflow more suitable outside-in/ui tests. (for example, web tests simulate mouse-clicks, etc, using watin or similar.) apparently mspec more suitable unit-tests. now question - why use 2 frameworks incredibly similar , virtually same thing? why not instead: choose 1 bdd framework , stick it. use outside-in/ui tests, intended, write unit-tests normally, established unit-testing framework (such nunit, mstest, etc)? i thought reason adopt bdd can test behaviours, driven externally , means of integration tests. i don't see how/why applies unit tests. i agree darren. think partly cultural/learning thing. if want have business actively collaborating on executable specification do, need business readability. need bdd tool, specflow. for unit testing, "business" or other developers in team, constraint have write unit tests in way other develop

i have problem application: application has many forms , need 1 hour finish form because form dynamic (can add other forms). problem is: session of web server 24 minutes. when user fill form, spent time , session timed out because server recognize user inactive. it's annoying when form submitted, data lost , user returned login page. have tried make session expired in 10 hours code: ini_set('session.gc_maxlifetime', '36000'); but it's not working in server, possible server preventing ini_set() function? so, should solving problem? can prevent session timeout session can expanded 10 hours? or can disable session expiration? thanks instead of setting time in ini fixed length, remind session timeout reset on reload. create ajax code request every 5 minutes or file (image or smth). way timer reset every 5 minutes , users can spend day filling out forms.

when in eclipse use method throws exception, complains if not surrounded try/catch or if exception not thrown again. exceptions (e.g. integer.parseint(string)) eclipse won't complain. how set eclipse complain not handled exceptions?? thanks! the simple answer can't. the longer answer is: checked versus unchecked exceptions fundamental part of java language. it not role of eclipse compiler give compilation errors or warnings valid , acceptable java. you wouldn't want either, considering majority of statements (in theory) throw or propagate exceptions such nullpointerexception , arrayindexoutofboundsexception , outofmemoryerror , , on. yes, there 1 or 2 "mistakes" ... such numberformatexception being unchecked exception ... better way deal (for example) run pmd custom rules pick exceptions "ought be" treated checked.

in windows server 2008 datacenter, not find powershell webadministration module. tried get-pssnapin , get-module -listavailable , neither of showed webadministration and don't see webadministration module under directory %systemroot%\system32\windowspowershell\v1.0\modules !! do need install or enable have webadministration on datacenter ? you need have web server role (iis) installed. webadministration module. so, use get-module -listavailable also, looks these cmdlets available on windows server 2008 r2 or iis 7.5. so, if have iis7.5 on windows server 2008, these cmdlets available.

i can't seem make boost::ptr_unordered_map<uint32_t, const foo> work - underlying implementation looks it's casting things void* . do have bite bullet , make methods wrap access const_cast<foo*> when inserting items, or there i'm missing here? there way store pointers const objects ( const foo* )? it looks isn't possible. a workaround wrap access ptr_unordered_map . insert method should take const auto_ptr , const_cast<foo*> insert it. if hand auto_type client code when removing elements, you'll need unpack pointer , transfer const auto_ptr or similar make ownership transfer explicit without leaking non-const references. this sufficient use case, don't need expose iterator behaviour - it's pure single-element insert/release/look-ups.

i appreciate following issue: i have gadget camera, producing h264 compressed video frames, these frames being sent application. these frames not in container, raw data. i want use ffmpeg , libav functions create video file, can used later. if decode frames, encode them, works fine, valid video file. (the decode/encode steps usual libav commands, nothing fancy here, took them almighty internet, rock solid)... however, waste lot of time decoding , encoding, skip step , directly put frames in output stream. now, problems come. here code came producing encoding: avframe* picture; avpicture_fill((avpicture*) picture, (uint8_t*)framedata, codeccontext->pix_fmt, codeccontext->width, codeccontext->height); int outsize = avcodec_encode_video(codeccontext, videooutbuf, sizeof(videooutbuf), picture); if (outsize > 0) { avpacket packet; av_init_packet(&packet); packet.pts = av_rescale_q(codeccontext-&

i using mercurial command line , can't find out how tag folder. source repository consists different libraries i'd tag them separately. mistakenly tagged whole source tree, i'd know how erase tag before create new tag. as lasse states, can tag revision of entire repository in mercurial. in order tag different components in repository consider using mercurial subrepositories . subrepositories allow treat individual components (what calling libraries) independent repositories, , pull them single, functional unit. in terms of bitbucket's limitation on private repos - consider making of them public, or placing main repository on local machine or server if you're concerned exposing source publicly. if you're interested in hosting yourself, redmine free tool allow serve many repos want.
