i developing application uses edmx dataaccess. realized each edmx file have own connection string in configuration file. there way share 1 connection string edmx files? no - there isn't. and reason. connection string in entity framework contains more regular connection strings (e.g data source / database name). it contains crucial information different components of model, including csdl, unique model . perhaps explain if planning share connection string between different edmx's, why need seperate edmx's in first place? if looking @ way dynamically create connection string @ entityconnectionstringbuilder.

could start using codecontracts instead of: if (xxx == y) throw new argumentexception("bla bla"); how work if develop library , library users not use codecontracts? assuming code using code contracts run through binary rewriter, throw exceptions code posted. re-writer goes through code , replaces contract code argument checking etc. it's kinda aspect oriented programming. injects code handle situations after you've compiled it. if don't use code contracts not benefit of having static analysis performed designed @ contract , warn them might error based on contract , code. code contracts

hey guys using posix api system calls read , write , open , etc. can open, read, write file , copy contents output file. how go copying more 1 file output file using related system calls only? i have: filein = open(argv[1],o_rdonly,0); to open 1 file.(which argv1 i'd know how argv2 , argv3 etc.) i tried : j=0; filein = open(argv[j],o_rdonly,0); but prints out contents of argv0 outputfile. i stuck on next stage more 1 file. (i have eof loop after 1 file exits-how make continue next file). please me how approach next stage? thanks. background argv[0] name of program. argv[1] 1 st command line parameter. argv[2] 2 nd command line parameter. etc. so: start loop @ 1 , instead of 0 (i.e., j=0 incorrect). be sure close file after reading , before opening next file. algorithm think algorithm before writing code. set counter index of first argument. open file. assign handle open file. read file contents. write (if required) fil

since sqlite engine not truncate data store in text column, there advantage in being specific column sizes when define schema? prefer this: create table contact( id integer primary key, name varchar(45), title varchar(10) ); over this: create table contact( id integer primary key, name text, title text ); why? are there advantages not being specific? the advantage of using varchar(x) is compatible other database systems - if remember correctly, text isn't standard sql datatype. other being more standards-compliant, there indeed no difference whether use text or varchar. more info @ http://sqlite.org/datatype3.html

i'm using enable_shared_from_this<base> , inherit base . when trying use shared_from_this() in derived 's constructor (not initializer list), exception. turns out internal weak pointer null , doesn't point this @ all. how can happen? other use case of works fine. don't know start. looked down @ source code of enable_shared_from_this , , looks me pointer nullptr. you cannot call shared_from_this() in object's constructor. shared_from_this() requires object owned @ least 1 shared_ptr . object cannot owned shared_ptr before constructed. i guess internal weak pointer set when shared_ptr takes ownership of object first time. before point, there no reference count struct weak pointer can reference.

oracle jdbc driver 11.2.x: should rely on implicit statement cache or should invoke setpoolable(true) on each created statement? differences, advantages , disadvantages of both methods? statement caching improves performance caching executable statements used repeatedly, such in loop or in method called repeatedly. when enable implicit statement caching, jdbc automatically caches prepared or callable statement when call close method of statement object. invoking setpoolable(true) on each created statement caches statement. i'd you're better off relying on implicit statement cache. here's oracle's documentation on statement , result set caching oracle 11.2.

i have model organisations (nested set). have model people. person can have person deputy. organisation owned person. organisation visible owning person or deputy. i retrieve organisations visible given person, ie. organisations owned person or owned people, given person deputy: o = arel::table.new(:organisations) p = arel::table.new(:people) pd = p.where(p[:id].eq(3).or(p[:deputy_id].eq(3))).project(:id) op = o.join(p).where(o[:person_id].in(pd)).project("distinct organisations.*) there better way formulate last join, split query people , deputies query of organisations visible people , deputies. the last join returns arel::selectmanager (for there seems no useful documentation anywhere). is there way convert selectmanager activerecord::relation benefit whole concept of "closure under composition"? how self join above query on organisations again obtain descendants of organisations visible person or deputy? know sql fail selectmanager self join on organi

i have 2 threads need send tcp messages using same stablished connection. have object lets tcpsender use booth threads. how can design software in order not have concurrency problems , lost messages? thanks! you model producer/consumer each thread injects messages tcpsender whenever ready , tcpsender maintains fifo queue of messages. insertions queue locked (within tcpsender ) , processed in-order. there thread consuming messages when queue not empty locking each time message removed queue. two immediate benefits can support arbitrary number of producers , blocking limited inserting queue , not sending messages (from point of view of producer, is).

when running sweave emacs-ess, errors provided code chunk number. there easy way navigate among code chunks number? otherwise, difficult identify. i don't use emacs-ess (i use eclipse/ statet) shows code chunks being processed label (each code chunk starts <<label="some text"... code chunks include labels ?

i've looked around, , can't quite figure 1 out, , multitude of trial , error attempts have been useless. i have list of user names (we'll call 'original list') 1 object returning have list of user names (we'll call 'filtration list') object returning i testing method returns of items original list not in filtration list. ideally want like assert.that(returnedlist, has.no.members.in(filtrationlist)) so far thing can iterate on filtrationlist , do assert.that(returnedlist, has.none.equalto(filtereduser)) with nunit can create custom constraint. if want verify 2 collections intersection, can create this: public class intersects : collectionconstraint { private ienumerable _collection2; public intersects(ienumerable collection2) : base(collection2) { _collection2 = collection2; } public static intersects with(ienumerable arg) { return new intersects(arg); } protected overr

so have script in place needs go through each p tag within parent div class name of entry-content , translate each 1 using google translate api. so when user clicks link translate page english spanish function run: function spanish() { $(".entry-content p").each(function(){ var text = $(this).html(); google.language.detect(text, function(result) { google.language.translate(text, "en", "es", function(result) { if (result.translation) { alert($(this).html()); //outputs null $(this).html(result.translation); //doesn't work } }); }); }); } the problem when iiget inner function $(this).html() comesback null , not able change current elements html in order change new translated text. so guess question is: how pass current selected element nested functions? thanks you may store in local variable the value of this relate contex

i'm coding standard defined in xml. standard has provided me 2 xsd's must support. breaking changes in backwards compatibility. question general 1 in best practice implement these. went down path of using "xsd.exe" generate class files model xml in typed manner. brought me conclusion there not way version class files in c# other overriding methods not clean me since changes pretty significant in terms of properties ect. so initial idea use standard xml parsing in each versioned processor , not worry typed models, write lot more code( , less clean code ) in process. second idea version model , processor names xsd version ( tag in xml ) id have class named "equipment_1_0" , "equipment_1_1" , use factory return me proper type de-serialize seems hacky. and final idea turn here because these seems issue many people have addressed before. insight or resources can point me in terms of best practices in situation? thanks i suggest usi

i need 1 of 2 things in drupal have ability set info message specific user view next time login. message show in standard $messages variable. looked see if drupal_set_message() had capabilities didn't find it run function everytime page loaded info cause drupal_set_message sent i prefer second option, if has suggestions. i place code in hook_init(). of drupal has been loaded , available on every page load. within that, query list of messages form database , funnel them drupal_set_message(). $messages variable stored in session, need call drupal_set_message() @ time want show message. storing need present message different challenge, , depends on how determine message needs set. if based on elapsed time, can skip custom coding , go straight rules--defining triggers , actions based on user login date. if more dynamic messaging scheme, need notify users of events have happened in absence, might use write code based around message module or it, allow record m
