i have pair of tables parent-child relationship. domain: id int not null auto_increment primary_key domain varchar(100) not null domain_url: id int not null auto_increment primary key domain_id int not null path varchar(512) here want keep path unique in 1 domain. across domain path can duplicating. best constraint apply on path. should focus on composite key between domain_id , path. composite key reliable solution? i think want apply unique constraint in domain_url table on domain_id, path composite key. enforce requirement "to keep path unique in 1 domain"

i thought enough requirement class should satisfy able use where() implement ienumerable . but today friend of mine asked me question, why cannot apply where() object of spusercollection class (it sharepoint). since class derived spbasecollection implements ienumerable - expected should fine. not. any ideas, why? the linq extension methods defined on ienumerable<t> , not ienumerable . example, see where<t> signature: public static ienumerable<tsource> where<tsource>( ienumerable<tsource> source, func<tsource, bool> predicate ) to mitigate issue, linq cast<t> extension method turns ienumerable ienumerable<t> can used normal linq functions. in example below, can't e.where(...) , can cast , use where . int[] xs = new[] { 1, 2, 3, 4 }; ienumerable e = xs; var odds = e.cast<int>().where(x => x % 2 == 1); unfortunately, needs used lot when dealing pre-generics apis in .net bcl.

say have deal ushort , uint way, string differently. guess need 1 specialized template string , other both ushort , uint . it? // void func(t)(t var) { ... } // uint , ushort void func(t: uint, ushort)(t var) { ... } that idea, although code can't compile. it's valid or bad? try this: void func(t)(t var) if ( is(t : uint) || is(t : ushort) ) { ... } void func(t : string)(t var) { ... } you in 1 function: void func(t)(t var) { static if ( is(t : uint) || is(t : ushort) ) { ... } else if ( is(t : string) ) { ... } else { // handle else } }

hai, can me change "wed sep 29 14:47:37 +0000 2010" "sep 29,2010 @ 2:47pm" using regular expression in php? you can use strtotime . no need regular expression. date('m j, y \a\t g:i a', strtotime('wed sep 29 14:47:37 +0000 2010'));

i have 20,000 records (coming sqlite db) need present user possible choices, conventional picker control out of question. another possibility indexed uitableview user check desired value, keeping 20k records in memory doesn’t seem idea. how should go implementing ui it? edit: possible auto-complete combo-box? i'd @ sort of nested ui i.e. uitableview has a, b, c etc start , when user presses on row show table view results starting a. there need query got number of results started a, b, c etc showed letters in first table has results each query in second table simple - results starting 'a' etc. you'd never have load 20,000 results memory @ same time :) however, should make sure have index on field you're querying, otherwise queries going rather slow :( the other solution use search box @ top of table view - user types in letters , each time list reduced results starting letter. that's pretty simple query implement :) however, still h...

in class we're learning how build spring application, though spring isn't directly involved, learned how make interfaces dao , service layer objects. please correct me if i'm wrong: dao layer pretty abstract: contains crud operations , further used read data.(ie: objects, specific objects, etc) service layer: contains services create things, , delete things, business logic should be. now of makes sense in service layer; except "updating" objects. put "update" function saves object in database? or need define logic there well? confusion as, understanding objects in spring pojo's. validates data? let's have object "child" has: name , surname , gender , photo , birthdate fields. how name services? or let controller take care of validation, doesn't seem right me. on other hand wouldn't seem right either delegate every setter needs called service layer. so basically: me how define saving objects via service layer. ...

(interesting in linux , darwin, windows.) i don't know off-hand, study source. on ubuntu box, route provided net-tools : ~$ route /sbin/route ~$ dpkg -s /sbin/route net-tools: /sbin/route so make directory somewhere, run apt-get source net-tools . poked source, , route.c looked place start. if there's no arguments passed route , calls route_info() given address family , options, grep that: ~/z$ g...

i'm writing testing application i'm using test rest of code base. i'd able when test using manage.py command, automatically change logging different database. there way this? django automatically creates , drops test database you. unless otherwise specified (we'll see how in second) test_ + <the name of database in settings file> . if settings uses database foo , tests executed against test_foo . no configuration changes needed this. if wish execute tests against custom database (rather test_foo ) can tweaking test_name setting . can add test_name each dictionary in databases .

how change property of control in flowlayoutpanel assuming add controls programatically , assuming name of each controls same? for example image shows there 2 text boxes , 2 buttons, how change color of button 2? assuming controls has been added @ runtime. foreach(controls ctrl in flowlayoutpanel1.controls) { //what should put here? } well, easiest way retain explicit reference buttons you're adding. otherwise add tag distinguish them (to robust against i18n issues). e.g. can set tag of "button2" "button2" , can use: foreach (control ctl in flp.controls) { if ("button2".equals(ctl.tag)) { ctl.backcolor = color.red; } } i assuming problem find actual button again , not setting background color. likewise check control being button , text being "button2" if text can change depending on ui language that's not idea. eta: totally forgot can use control's name property well. if want change backg...
