i thinking of writing ui tests in backbone.js , jquery. may not best way it's thinking - automate tests without record , playback - through plain code. the thing made me scratch head using approach this: in 'use-case flow' (of execution) confirm/alert dialogs show up. i'd click 'ok' , continue flow - doable through plain javascript code? how? note: know gui testing libraries exist, want know how using jquery/javascript code, if @ possible. as far know if use standard alert() call cannot trigger "ok" click because alert call blocks normal js event loop. however should able replace window.alert , window.confirm own function nothing: window.alert = function() { console.log.apply(console, arguments); }; place these @ top of js before else loaded , subsequent calls alert() or confirm() call these instead.

i under impression "a d interface file contains import of module needs, rather whole implementation of module." me, translates signatures - return types, names , arguments, compiler knows it's valid , linker can dirty work later. running file through dmd , though, strips nothing: import std.stdio; void sayhello(const string name) { writeln("hello, ", name, "!"); } dmd interface.d -o- -h // d import file generated 'interface.d' import std.stdio; void sayhello(const string name) { writeln("hello, ",name,"!"); } hardly paragon of optimization. what, exactly, stripped in interface files? ( header-files added because it's closest thing find.) any function going inlined must have full source in .di file. function going used in ctfe must not have full source in .di file, full source of every function uses - directly or indirectly - must available compiler. also, because of how templates wo...

let's have function inserts records database table string fields of limited length. in general, @ point should truncating strings long storage location, in insert function itself, or @ every point in code it's called? (i'm assuming here truncation of strings long more desirable having exception thrown.) i think depends on function , how accessible is. if it's private function makes own sql library can away truncating in function. if it's in library that, say, team @ work use perhaps need @ least parse string before attempting insert it. if it's public api, shouldn't silently truncating - throw meaningful exception instead.

i'm trying send public key on socket connection in java. while i'm conscious java provides ssl functionality sort of activity, uni assignment; cannot use java implementation. the server encodes public key , transmits client via socket connection. when client receives key , decodes it, appears different. not this, data received client appears different transmitted server. believe giving me problems when attempt encrypt user name , password using key. the problem can reproduced following code: client: public class testclient { /** * @param args */ public static void main(string[] args) { final int sport = 4321; socket sock = null; key serverpubkey = null; bufferedreader clientin = null; // initialise server connection try{ sock = new socket(inetaddress.getlocalhost(), sport); clientin = new bufferedreader(new inputstreamreader(sock.getinputstream())); } catch (unknown...

the following simple example of multi-player game many games played on several seasons. game id, player name , score of each player , season being played recorded in table. queries below show how 1 can derive summary of player's rank games played in particular season. select game, score table name='name' , season='season' order game; while(fetching result) { select count(*) 'total', sum(case when score>='score' 1 else 0 end) 'rank' table game='game' , season='season'; } the output contains game , score , rank , total games played player in particular season, order game . wondering whether there more efficient ways instead of using while loop. sorry, got confused column name when first posted. cannot make of optimization here in query itself, because second time want data games, not player trying rank. can add them subqueries/joins first, second query works more 1 row, can done, result in addit...

the following code claimed use loop flag repeat input until valid int obtained. { try { // attempt convert string int n = integer.parseint( s ); goodinput = true; } catch ( numberformatexception nfe ) { s = joptionpane.showinputdialog( null, s + " not integer. enter integer" ); } } while ( !goodinput ); i little confusing logic here. if integer.parseint works fine, or there no exception occuring, "goodinput" assigned "true" @ line of goodinput = true; then !goodinput evaluated false, while loop continue again. seems me contradicts designed logic, i.e., while loop should stop after performing correct parse operation. wrong analysis above. do { } while(x); loops while x == true , i.e. until x == false . therefore, do { } while(!x); loops while x == false , i.e. until x true .

i use registration form asks users enter full name 1 input field. php class parses first , last name , inserts our db. found out our billing system doesn't receiving first name have validate form field , make sure there 2 strings entered. fiddle of basic input validation i'm not , writing rule check 2 strings. appreciated thanks http://jsfiddle.net/peter/4x3mx/1/ you try with: $(document).ready(function() { $("#btn").click(function(e) { if (/\w+\s+\w+/.test($("#cname").val())) { alert("good"); } else { alert("bad"); } e.preventdefault(); }); }); fiddle: http://jsfiddle.net/yrffg/
