i'm attempting build custom control formtastic takes latitude , longitude, however, i'm not sure how go passing method names through. ideally i'd have following in semantic_form_for block: f.input :latitude, :longitude, :as => :location i've tried passing array: f.input [:latitude, :longitude], :as => :location but in both cases, fails - first on number of parameters, second on first parameter not being symbol. is there way of passing 2 methods #input i'm missing? ok, i've sorted out writing a plugin formtastic . i've added multi_input function can take number of parameters , (optional) options hash. i've added map_input type outputs map control , js (framework agnostic). more details @ above link.

i'm working old database used other applications, can't modify structure. have nullable columns want map non nullable type. instance have nullable endvalidity column on database want map on non nullable datetime, and, if null, should datetime.maxvalue, or more simple example, nullable bit column must false if null. i'm thinking writing custom user type (with parameters if possible), or there included in nhibernate it? if solution write custom usertype, boolean case, can override fluentnhibernate conventions apply usertype booleans? it depends on how want poco class act. firstly if load null value want null value re-saved or want session commit/flush update record new default null field. if want keep null value in db how detect poco object boolean value save ie booleans have true , false options / values bit class has options / values of null, 0 , 1? if say: want have nullable bits boolean , not nullable boolean dataype in poco class , have class update db...

i dabbling in world of web services , i've been making simple web service mimics mathematical operations. firstly simple, passing in 2 integers , binary operator applied these (plus, minus etc) depending on method called. then decided make things little more complex , started passing objects around, discovered web service exposes data side of class , not functional side. i told way deal make class on service side partial class (this side of class encapsulating form) , on client side have partial class (where side of class encapsulates functionality). seems elegant way of doing things.. so, have set 2 classes described above, doesn't seem working told. is attempting possible? if so, going wrong? partial classes tool separate auto-generated code developer code. a example windows forms designer in vs, or new dbml linq datacontext generated code. there's argument using them vss style source control providers 1 user can edit file @ 1 time. it's not...

i need render line break using outputtext can utilize rendered attributed. tried <h:outputtext value="<br/>" escape="false" /> but generated exception the value of attribute "value" associated element type "null" must not contain '<' character. that's indeed not valid since facelets because it's syntactically invalid in xml. you'd need manually escape xml special characters < , > , on. <h:outputtext value="&lt;br/&gt;" escape="false" /> you can emit <br/> in template text without need <h:outputtext> . <br/> to render conditionally, wrap in example <ui:fragment> . <ui:fragment rendered="#{bean.rendered}"><br /></ui:fragment> a <h:panelgroup> valid doesn't emit html anyway. <h:panelgroup rendered="#{bean.rendered}"><br /></h:panelgroup>

i've been trying create units tests legacy code. i've been taking approach of using linker show me functions cause link errors, greping source find definition , creating stub that. is there easier way? there kind of c++ parser can give me class definitions, in easy use form, can generate stubs? you may want investigate http://os.inf.tu-dresden.de/vfiasco/related.html#parsing . c++ parsing hard. on other hand, maybe ctags or similar can extract class definitions... you may try write own simple (?) parser generate class stubs header files... i tried give pointers. see, problem not easy. can automate @ least part of it.

what elegant way iterate words of string? string can assumed composed of words separated whitespace. note i'm not interested in c string functions or kind of character manipulation/access. also, please give precedence elegance on efficiency in answer. the best solution have right is: #include <iostream> #include <sstream> #include <string> using namespace std; int main() { string s = "somewhere down road"; istringstream iss(s); { string subs; iss >> subs; cout << "substring: " << subs << endl; } while (iss); } for it's worth, here's way extract tokens input string, relying on standard library facilities. it's example of power , elegance behind design of stl. #include <iostream> #include <string> #include <sstream> #include <algorithm> #include <iterator> int main() { using namespace std; string sentence ...

i'm not sure how online... think might called different in c++ i want have simple event system, somthing like event mycustomevent; mycustomevent.subscribe( void myhandler(string) ); mycustomevent.fire("a custom argument"); // myhandler prints out string passed in first argument event mynewcustomevent; mynewcustomevent.subscribe( void mynewhandler(int) ); mynewcustomevent.fire(10); // myhandler prints 10 i can pretty simple class -- when want have event passes different type or amount of arguments subscriber have write, , define entirely new event class.. figure there has library, or maybe native in visual c++ 2008 work similar this. it's basicly implementation of observer pattern, can't impossible in c++ this makes me appreciate how nice in javascript not have worry arguments passing. tell me if stupid question. i use sigslot purpose.

i'm writing little scripting language bit of fun , learning of codes :p i opinions/suggestions. have idea don't want include people going want spit on. plan on making language open source once, soon. does think cool have like: [foreach] uppercase letter s in case-insensitive word sallysawtheseafishandateit: count++. s.highlight: true. runonce.protectedmethod.activateprotectedmethod: istrue. [protected method.lockto: [foreach]].istrue statusbar.message: match s found. total: count.. runonce.protectedmethod.disable. explanation: above searches through string of text "sallysawtheseafishandateit" , highlights every single match. when finds first match "s", runs method called "istrue", , sets statusbar text "match found...". , deactivates runonce method may no longer accessed, since there's no need run again. this might not best example, think idea. there have be...

does use xml in message? there alternatives xml? if use xml, define xml schema clients know how send messages service? we use xml, think important thing tailor solution problem. reason use xml sending object across in message. there's no reason can't plain text, if applicable message sending, using headers send along properties if appropriate. haven't defined xsd or dtd our xml messages, have formal document describing composition other teams can use our feeds without bugging us.

i'm writing simple c++ class in cache picture thumbnails versions of images downloaded web. such, use hash function takes in url strings , outputs unique string suitable filename. is there simple way without re-writing function myself? searched around simple library, couldn't find anything. surely common problem. a simpler approach replace not character or number underscore. edit: here's naive implementation in c: #include <cctype> char *safe_url(const char *str) { char *safe = strdup(str); (int = 0; < strlen(str); i++) { if (isalpha(str[i])) safe[i] = str[i]; else safe[i] = '_'; } }

i'd receive error logs via email. example, if warning-level error message should occur, i'd email it. how can working in codeigniter? you extend exception core class it. might have adjust reference ci's email class, not sure if can instantiate library this. don't use ci's email class myself, i've been using swift mailer library. should on right path. make file my_exceptions.php , place in /application/libraries/ (or in /application/core/ ci 2) class my_exceptions extends ci_exceptions { function __construct() { parent::__construct(); } function log_exception($severity, $message, $filepath, $line) { if (environment === 'production') { $ci =& get_instance(); $ci->load->library('email'); $ci->email->from('your@example.com', 'your name'); $ci->email->to('someone@example.com'); $ci-...

this freakin weird me. if don't function bindalbumandphotodata() { // array of user's albums var aalbums = getallalbums(userid, token); alert("aalbums: " + aalbums); if (aalbums == null || aalbums == "undefined") return; // set default albumid var defaultalbumid = aalbums[0].id; }; so undefined error on line var defaultalbumid = aalbums[0].id; if don't uncomment alert("aalbums: " + aalbums); what heck? if comment out alert("aalbums: " + aalbums); undefined var defaultalbumid = aalbums[0].id; this weird. i've been working night figure out why kept getting undefined aalbum[0] , add alert used have above it, fine...makes no sense me. here's full code of getallalbums: function getallalbums(userid, accesstoken) { var aalbums = []; // array var uri = "/" + userid + "/albums?access_token=" + accesstoken; aler...

the idiom use when programming in java test if object != null before use it. avoid nullpointerexception . find code ugly, , becomes unreadable. is there alternative this? i want address necessity test every object if want access field or method of object. for example: if (someobject != null) { someobject.docalc(); } in case avoid nullpointerexception , , don't know if object null or not. these tests appear throughout code consequence. this me sounds reasonably common problem junior intermediate developers tend face @ point: either don't know or don't trust contracts participating in , defensively overcheck nulls. additionally, when writing own code, tend rely on returning nulls indicate requiring caller check nulls. to put way, there 2 instances null checking comes up: where null valid response in terms of contract; and where isn't valid response. (2) easy. either use assert statements (assertions) or allow failure (for example, ...

note: examples below c# problem should not specific language in particular. so building object domain using variant of s# architecture . unfamiliar it, , save reading time idea have data access object interface each of domain objects responsible loading to/from persistence layer. might ever need load/save given object accepts object's data access interface dependency. example can have following product lazy load customer purchased needed: public class product { private icustomerdao _customerdao; private customer _customer; public product(icustomerdao customerdao) {_customerdao = customerdao;} public int productid {get; set;} public int customerid {get; set;} public customer customer { get{ if(_customer == null) _customer = _customerdao.getbyid(customerid); return _customer; } } public interface icustomerdao { public customer getbyid(int id); } this , until reach situation 2 objects need able load each other. examp...
