java - How to expand entries in a TableViewer -

java - How to expand entries in a TableViewer -

i created eclipse plugin simple hashtable:

private hashtable<string, packageobject> _packagetabelle;

i filled table

_packagetabelle.put(packageid,new packageobject(packageid, stageid));

the result table entries. display colum in tableviewer.

for example:

package id: stageid: 1 10 2 20 3 30 4 40 5 50

now want expand column clicking in front end of it. result should this:

package id: stageid: 1 10 --> bundle id def stageiddef 3 7 bla bla 2 20 3 30 4 40 5 50

does have idea?

the "_viewer" tableview.

_viewer = new tableviewer(parent, swt.multi | swt.h_scroll | swt.v_scroll | swt.full_selection); _viewer.setcontentprovider(new viewcontentprovider()); _viewer.setlabelprovider(new viewlabelprovider()); _viewer.setsorter(new namesorter()); _viewer.setinput(packagetabelle.getinstance().getpackageobjects()); table table = _viewer.gettable(); table.setheadervisible(true); table.setlinesvisible(true); table.getverticalbar().setvisible(true); // tabellenstruktur aufbauen tablecolumn column = new tablecolumn(table, swt.left); column.settext("package"); column.setwidth(100); column.addselectionlistener(new columnsortlistener(1, _viewer)); column = new tablecolumn(table, swt.center); column.settext("stage"); column.setwidth(100); column.addselectionlistener(new columnsortlistener(2, _viewer)); column = new tablecolumn(table, swt.left); column.settext("beschreibung"); column.setwidth(400); column.addselectionlistener(new columnsortlistener(3, _viewer));

i adding angularjs project , need count length of textarea, incrementing total number of "pages" (messaging app) every 160 characters - , decrementing if text deleted.

i'm guessing best place handle logic determine number of pages in javascript code cannot figure out how link ng-model code. help appreciated.

there's no need ng-change, can in dom directly:

Save custom objects when activty stops on Android -

Save custom objects when activty stops on Android -

i've written little andorid app. app uses vector of custom objects , displays them in listview. want save objects when activity send background. best way this. in vector 25 objects. every object has boolean, 2 long, , 2 strings.

thanks help

do need them saved when app shuts downwards or when activity goes background?

if objects parcelables utilize save , restore instance state methods:

@override protected void onsaveinstancestate(bundle outstate) { super.onsaveinstancestate(outstate); outstate.putparcelablearraylist("objectsarray", myobjects); // if array of parceleble objects } @override protected void onrestoreinstancestate(bundle savedinstancestate) { super.onrestoreinstancestate(savedinstancestate); myobjects= savedinstancestate.getparcelablearraylist("objectsarray"); }

java - How to write the result of a rule, into a model (in Jena)? -

i working on project need create rules using jena freamwork.

i have created rules , work should. can see output on screen storing result model of ontology have.

i have code :

@prefix ex: <http://www.semanticweb.org/prova_rules_m#> . @prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . @prefix xsd: <http://www.w3.org/2001/xmlschema#> . @include <owl> [pippo: (?p http://www.semanticweb.org/prova_rules_m#anni_persona ?x) <- (?p rdf:type ex:persona) (?p http://www.semanticweb.org/prova_rules_m/persona#data_nascita ?c) mydiffdateyear(?c,"2014-06-18t00:00:00.0"^^xsd:datetime,?x) ]

in illustration using custom built-in have created previously. returns number of years of difference between 2 dates. can see output in screen next code :

string percorsofile ="./prova_rules_m_rdf.owl"; string rulefile= "./prova_rules_m_rdf_7_diffdate.txt"; model rawmodel = modelfactory.createdefaultmodel(); //create resource (empty model) resource configuration = rawmodel.createresource(); // set engine mode configuration.addproperty(reasonervocabulary.proprulemode, "hybrid"); // set rules file configuration.addproperty(reasonervocabulary.propruleset, rulefile); list<rule> rules = rule.rulesfromurl(rulefile); genericrulereasoner reasonerrule = (genericrulereasoner) genericrulereasonerfactory.theinstance().create(configuration); reasonerrule.setrules(rules); model modelrule= filemanager.get().loadmodel(percorsofile); //create inference model infmodel infmodelrule = modelfactory.createinfmodel(reasonerrule, modelrule); //force starting rule execution infmodelrule.prepare(); //write downwards result in rdfxml form infmodelrule.write(system.out);

how can write result of info property "anni_persona" within model (and not output) ?

thank you.

the way backwards chaining inference rule works when associated model (in case, infmodelrule), inferred tripled available when attempts read model.

for example, if asked if infmodelrule.contains(...) triple know inferred , see in output, you'll true result. model doesn't need separate step 'write' result.

if write model disk instead of standard out (psudocode):

try( final fileoutputstream out = new fileoutputstream(new file("blah.rdf")) ){ infmodelrule.write(out); }

... you'll see triples inferred there well. if later read file model without reasoner attached, triples remain.

c# - How to ignore nested enums from mapping -

c# - How to ignore nested enums from mapping -

i have several reference entities nested enums convenience. example:

public class statusa { public enum values { active = 1, inactive = 2, inprogress = 3 } } public class statusb { public enum values { sent = 1, accepted = 2, expired = 3 } } public class entitya { public statusa.values status {get; set;} } public class entityb { public statusb.values status {get; set;} }

i'm getting next exception @ time of model configuration: the type 'statusa+values' , type 'statusb+values' both have same simple name of 'values' , cannot used in same model. types in given model must have unique simple names. utilize 'notmappedattribute' or phone call ignore in code first fluent api explicitly exclude property or type model.

trying prepare found out notmappedattribute not applicable enums. tried fluent api .ignore<t> (which requires ref type, not enum) , .ignore(ienumerable<type>), no luck. google search not helpful.

is there other way exclude enums model?

you should enumeration type in model if include property of type. if that, there cannot way of ignoring type, without ignoring property. , testing shows ignoring property sufficient ignore type.

here's minimal finish test programme exception you're getting:

using system.data.entity; using system.data.entity.infrastructure; public class { public int id { get; set; } public e p { get; set; } // #1 public enum e { } } public class b { public int id { get; set; } public e p { get; set; } // #2 public enum e { } } static class programme { static void main() { var modelbuilder = new dbmodelbuilder(dbmodelbuilderversion.latest); modelbuilder.entity<a>(); modelbuilder.entity<b>(); var model = modelbuilder.build(new dbproviderinfo("system.data.sqlclient", "2012")); } }

it should obvious long #1 , #2 both part of model, cannot avoid mapping enumeration types. , if remove either #1 or #2 (or both), or mark them notmapped attribute, see no longer exception you're getting now.

you may able avoid renaming enumeration type if can avoid mapping property of type, so:

public class { public int id { get; set; } public int pasint { get; set; } [notmapped] public e p { { homecoming (e) pasint; } set { pasint = (int) value; } } public enum e { } }

this old approach required when ef didn't back upwards enumeration types @ all. unfortunately, approach mean query context.as.where(a => a.p == e.c) won't work, because model doesn't know p property. need written context.as.where(a => a.pasint == (int)e.c). depending on needs, may enough, though.

$(".delete-size-row").click(function() { $('#removerow-unique').hide(); });

you can utilize .closest() find parent div class divtablerow can hide it.

asp.net mvc - ActionFilterAttribute mvc need to call One time -

i have scenario need check security each menu item if user 'a' allowed access menu or not , reason created class inherited actionfilterattribute

public class securityfilter : actionfilterattribute { public override void onactionexecuting(actionexecutingcontext filtercontext) { log("onactionexecuting", filtercontext.routedata); } }

and using class on controller

[securityfilter] public class xyzcontroller : controller { public actionresult index() { homecoming view(); } }

now problem in view have @html.action() calls e.g

@html.action("com")

which results in calling onactionexecuting method again, want phone call 1 time when menu link clicked , method menu redirecting not other action method render within view

when called using @html.action ischildaction property of filtercontext true. can rely on determine whether want or not:

public override void onactionexecuting(actionexecutingcontext filtercontext) { if (filtercontext.ischildaction) return; log("onactionexecuting", filtercontext.routedata); }

is there way r plots pop-up in separate window outside of rgui?

x11() in rstudio not in rgui.

thanks

if run cairo device cairodevice bundle graph shows in separate window (at to the lowest degree test on windows did).

if run rgui (on windows) in sdi mode instead of mdi mode standard graphics device different window command line (but scripts, help, etc. well).

the tkrplot bundle has tools creating graphs in separate tk window.

you send graph file, utilize shell.exec open viewer graphics file in separate window.

there may other ways well.

java - JTextPane autoscroll works only one time -

java - JTextPane autoscroll works only one time -

i have 2 jtextpane , set them autoscroll vertically, reason don't undertstand 1 working.

what reason?

jtextpane texta = new jtextpane(); texta.setname(text); texta.setcontenttype("text/html"); defaultcaret caret = (defaultcaret)texta.getcaret(); caret.setupdatepolicy(defaultcaret.always_update); jscrollpane filler = new jscrollpane (texta, jscrollpane.vertical_scrollbar_always, jscrollpane.horizontal_scrollbar_never); jtextpane textb = new jtextpane(); textb.setname(text + "_t"); textb.setfont(texta.getfont()); defaultcaret caret_t = (defaultcaret)textb.getcaret(); caret_t.setupdatepolicy(defaultcaret.always_update); jscrollpane filler_t = new jscrollpane (textb, jscrollpane.vertical_scrollbar_always, jscrollpane.horizontal_scrollbar_never); panel.add(filler); panel.add(filler_t);

filler_t (textb) 1 working

you have not used layout panel. jscrollpane filler_t placed on jscrollpane filler , jtextpane texta not visible.

use layout, illustration add together lines in code:

panel.setlayout(new borderlayout(0, 0)); panel.add(filler,borderlayout.north); panel.add(filler_t,borderlayout.center);

your window like:

full running code:

javascript - Can a variable change value during single function call (from the outside?) -

javascript - Can a variable change value during single function call (from the outside?) -

i have been meaning read entire ecma5-6 spec, cough, maybe y'all can help me instead!

can variable changed "the outside" on course of study of execution of single phone call in javascript?

pseudo-javascript example:

window.foo = true; startsomeloopmutatingfoo(); function f() { var = window.foo; // insert long, blocking work here, none of mutates window.foo var b = window.foo; // 1 time again if (a != b) { totalmindexplosion() } }

will mind blown? totalmindexplosion() called under conceivable circumstance?

here's js fiddle facilitate mind fracking: http://jsfiddle.net/mf3rc/

i'm looking resources larn when asynchronous methods executed, direct answers, or questions of clarity.

thanks so!

no, totalmindexplosion() not called.

when executed, code in closure (function) blocks process, there no chance execute other code.

example:

function(){ var = 1; window.settimeout(function(){console.log(a);}, 0); = 2; }()

this log 2 instead of 1, timeout 0 second. console.log function called after total function executed, time, variable 'a' has been set 2.

sql server - Concatenate rows from a complex select in SQL -

sql server - Concatenate rows from a complex select in SQL -

rdbms sql server 2008.

i have 3 tables. simplify this:

nominationorder table:

nominationorderid | nominationid 1 | 5 2 | 9

nominationorderitem table:

nominationorderitemid | nominationorderid | giftid 1 | 1 | 6 2 | 1 | 3 3 | 1 | 9

gift table:

giftid | giftname | 3 | tvset 6 | tabletpc 9 | littleponny

so, there's nomination. each nomination may have 1 nomination order. each nomination order may have many nomination order items, each of them references gift order.

i'm making study reporting services , need display info each nomination gift in single row, showing gift names concatenated.

currently looks this:

nominationid | nominationorderid | giftname 5 | 1 | tvset 5 | 1 | tabletpc 5 | 1 | littleponny

i need this:

nominationid | nominationorderid | giftname 5 | 1 | tvset, tabletpc, littleponny

a simplified illustration of current sql query:

select nn.nominationid ,n_o.nominationorderid ,g.name giftname dbo.nomination nn left bring together dbo.nominationorder n_o on n_o.nominationid = nn.nominationid left bring together dbo.nominationorderitem noi on noi.nominationorderid = n_o.nominationorderid left bring together dbo.gift g on g.giftid = noi.giftid

how can rewrite create output in single string , concatenate gift names?

you can utilize cte :

with ctetbl (nominationid, nominationorderid, giftname) ( query here)

and concatenate rows same nominationid , nominationorderid for xml path('') , after replace first comma , stuff:

select t.nominationid , t.nominationorderid , stuff( ( select ', ' + giftname ctetbl nominationid = t.nominationid , nominationorderid = t.nominationorderid order giftname desc xml path('') ), 1, 1, '') ctetbl t grouping t.nominationid , t.nominationorderid sqlfiddle

Checking if the Checkbox is checked or not dynamically in c# -

Checking if the Checkbox is checked or not dynamically in c# -

i have created checkbox dynamically button code

private void btn_add_record_click(object sender, eventargs e)q2 { checkbox deletecheckbox = new checkbox(); point p_request = new point(nxcheckbox, nycheckbox); deletecheckbox.location = p_request; deletecheckbox.name = "ch"+record_id+""; }

then checked manually need check specific checkbox name "ch"+record_id+" checked or not dynamically using code

string chechboxname = "ch1"; checkbox deletechechbox = new checkbox(); deletechechbox.name = chechboxname; if (deletechechbox.checked) { // code }

when debug code, doesn't come in if statement .. why ?

you're checking if box checked before gets checked. add together

deletechechbox.checkedchanged += deletechechboxcheckedchanged;

and add together method deletechechboxcheckedchanged can test whether or not it's been checked. can use

deletechechbox.checked = true;

to check box through code.

edit: checkbox it's name have either store global variable or through controls array in form.

foreach (control command in this.controls) { if (control.name == "ch1") { checkbox deletechechbox = (checkbox)control; if (deletechechbox.check) { //to code } } }

i have nstableview cells view-based.

datasource & delegate connected, i'm not able display cell's textfield string value.

this code in objective-c, working:

- (nsinteger)numberofrowsintableview:(nstableview *)tableview { homecoming 10; } - (nsview *)tableview:(nstableview *)tableview viewfortablecolumn:(nstablecolumn *)tablecolumn row:(nsinteger)row { nstablecellview *cell = [tableview makeviewwithidentifier:@"list" owner:self]; [cella.textfield setstringvalue:"hey, cell"]; homecoming cell; }

and here code in swift, not working :

func numberofrowsintableview(atableview: nstableview!) -> int { homecoming 10 //casual number } func tableview(tableview: nstableview!, cellforrowatindexpath indexpath: nsindexpath!) -> nstablecellview! { var cell = tableview.makeviewwithidentifier("list", owner: self) nstablecellview! // setup cell without forcefulness unwrapping cell.textfield.stringvalue = "hey, cell" println("method called") //never printed homecoming cell }

this result: (table on right side of image)

note comment //setup cell without forcefulness unwrapping it makes no sense, forgot delete it.

what missing ?

java short circuit operators -

java short circuit operators -

my uncertainty precedence of short circuit operators.

classic illustration of short circuit operator below.

if(denom != 0 && num/denom > 10 )

here usage of shorthand operator allows prevent partition 0 error because num/denom never executed.

now question java says '/' operator has higher precedence '&&' , how come left side of '&&' evaluated before '/'.?

/ has higher precedence >, has higher precedence &&. so, expression

a && b / c > 0

is same as

a && (b / c) > 0

which same

a && ((b / c) > 0)

the look evaluated left right.

if a false, entire look false, without evaluating sec term.

if a true, b / c first evaluated, , result compared 0.

nrclient nrclient = (nrclient)mockito.mock(nrclient.class); mockito.when(nrclient.uploadfiles("df49acbc8", anylist(), "dl")).thenreturn("");

this shows runtime exception: "the method anystring() undefined type maintest." have imports:

import org.mockito.mockito; import org.mockito.matchers;

so why method undefined? there issue in implementation?

i have tried anystring() , anyint() same result.

you should getting compile-time error, not exception (unless actual exception you've got unresolved compile-time error).

just importing org.mockito.matchers means can utilize name matchers mean org.mockito.matchers anywhere in class. if want import methods, need static wildcard import:

import static org.mockito.matchers.*;

or specific methods:

import static org.mockito.matchers.anystring; import static org.mockito.matchers.anylist;

or qualify method name in calling code instead:

mockito.when(nrclient.uploadfiles("df49acbc8", matchers.anylist(), "dl")) .thenreturn("");

java - Trying to exit in android. Stack is not correctly cleared -

java - Trying to exit in android. Stack is not correctly cleared -

i have been spending lots of hours figuring reason why top of stack not cleared yet.

well tried following:

intent intent = new intent(actionbaractivity.this, mainactivity.class); intent.addcategory(intent.category_home); intent.setflags(intent.flag_activity_new_task); intent.addflags(intent.flag_activity_clear_top); startactivity(intent);

and turned me mainactivity. when seek press button, programme not exit, instead turns me first page of actionbaractivity.

let me more specific:

in mainactivity phone call actionbaractivity. in actionbaractivity have search bar , come in query there , print value of query.

if think how work below:

mainactivity -> actionbaractivity1 -> actionbaractivity2 -> actionbaractivity3 -> ..

in actionbaractivity have alternative brings me mainactivity.

so said when run application way above, bring me mainactivity.

nice far, when press button expect exit, instead goes actionbaractivity1. uncertainty stack not erased.

what should in case. thanks

i'm assuming you've seen post: android: clear stack , not want

the flag_activity_new_task creating new task stack. when nail "back" activity in stack, android goes previous task - has calling activity @ top.

if remove flag, mainactivity in task stack , brought top. , "back" removes , brings calling activity. far, expected android behavior.

edit: since commented have 2 activities, 1 alternative "finish()" actionbaractivity after starts mainactivity this:

startactivity(intentmainactivity); finish();

to behavior want many activities or in situations, need utilize set_result , finish activities in stack when nail button go mainactivity. in other words, android assumes want maintain activities when new ones start. in case don't, have tell activity destroy itself.

i.e. phone call setresult(done) , utilize startactivityforresult , check "done" flag in onactivityresult method.

then this:

mainactivity -> actionbaractivity1 -> actionbaractivity2 -> actionbaractivity3 -> mainactivity

becomes:

mainactivity -> actionbaractivity1 -> actionbaractivity2 -> actionbaractivity3 -> phone call "done" destroy actionbaractivity3 destroy actionbaractivity2 destroy actionbaractivity1 mainactivity remains

for example, in actionbaractivity2:

startactivityforresult(intentactionbaractivity3, actionbaractivity2_id);

then in actionbaractivity3:

public void exitbutton(view view) { setresult(my_done_flag); finish(); }

and in actionbaractivity2:

protected void onactivityresult(int requestcode, int resultcode, intent data) { if (requestcode == actionbaractivity2_id && resultcode == my_done_flag) { setresult(my_done_flag, data); finish(); } }

and on activities want "close" when button pressed.

apache pig - Performance profiling in Pig Scripts -

some of pig scripts take long time execute info on run map cut down jobs huge. so, thinking of ways speed script . can suggest ideas , set thoughts . there lot of grouping fields involved while grouping info based on combination of 2 or 3 fields.

one thought can think of having 1 field while doing grouping by

data = grouping (int) (random()*100) reducers, field1, field2 etc

will help involve more number of reducers introducing 1 field in grouping by. know output part file sizes become lesser , overall speedify running time of pig scripts.

sorting - PHP Table Creation (Multidimensional Arrays) -

i have 4 arrays first beingness table headings there six:

array(6) { [0]=> string(3) "who", [1]=> string(4) "what", [2]=> string(4) "when", [3]=> string(5) "where", [4]=> string(3) "why", [5]=> string(3) "how" }

and 3 other arrays contain coinciding values. want take values of first array create them keys of array value or array so:

array(6) { ["who"]=> array(0) {}, ["what"]=> array(0) {}, ["when"]=> array(0) {}, ["where"]=> array(0) {}, ["why"]=> array(0) {}, ["how"]=> array(0) {} }

and populate arrays coinciding values much table. illustration of 1 of other arrays be:

array(6) { [0]=> string(3) "red", [1]=> string(4) "blue", [2]=> string(4) "green", [3]=> string(6) "yellow", [4]=> string(3) "black", [5]=> string(3) "white" }

for sake of simplicity going 3 arrays have exact same value 1 above.

in end want resulting array be:

array(6) { ["who"]=> array(3) { [0]=> string(3) "red", [1]=> string(3) "red", [2]=> string(3) "red" }, ["what"]=> array(3) { [0]=> string(4) "blue", [1]=> string(4) "blue", [2]=> string(4) "blue" }, ["when"]=> array(3) { [0]=> string(5) "green", [1]=> string(5) "green", [2]=> string(5) "green" }, ["where"]=> array(3) { [0]=> string(6) "yellow", [1]=> string(6) "yellow", [2]=> string(6) "yellow" }, ["why"]=> array(3) { [0]=> string(5) "black", [1]=> string(5) "black", [2]=> string(5) "black" }, ["how"]=> array(3) { [0]=> string(5) "white", [1]=> string(5) "white", [2]=> string(5) "white" } }

the code working follows:

... //tokens generated above (this in loop) foreach ($tokens $token) { if ($i == 0) { $table[$token] = array(); } else { foreach ($table $col) { $table[$col][$i] = $token; } } } $i = $i + 1;

all generates array(0) {}

it'd appreciated if point out flaw in logic.

edit:

here table like:

_________________________________________ | | | when | | why | how | ----------------------------------------- | reddish | bluish | green| yellow|black|white| ----------------------------------------- | reddish | bluish | green| yellow|black|white| ----------------------------------------- | reddish | bluish | green| yellow|black|white| -----------------------------------------

$tokens= array('who', 'what', 'when', 'where', 'why', 'how'); $table = array('red', 'blue', 'green', 'yellow','black', 'white'); $a = array_fill_keys($tokens, $table); print_r($a);

i'm getting null pointer exception , i'm confused. can help me please? if need more information,please allow me know.thanks in advance help.here's activity file:

mysql - Optimizing left join select query of large data in SQL -

mysql - Optimizing left join select query of large data in SQL -

i know if there faster or improve way of handling next situation:

i find myself struggling optimize execution time of lengthy select query, need create left joins each unique field per record (basically pivoting table). there way minimize single join/pivot cut down time taken retrieve data?

i need create provision 50 custom fields, times out on 30000 odd records (this indexes on relevant columns)

i appreciate help (that includes correcting title i'm not sure how state otherwise) in advance.

below code setup little example:

create table customfield ( id int identity (1,1) not null, fieldname varchar(50) not null, fieldordernumber int not null); alter table [dbo].[customfield] add together constraint [pk_customfield] primary key clustered ( [id] asc )with (pad_index = off, statistics_norecompute = off, sort_in_tempdb = off, ignore_dup_key = off, online = off, allow_row_locks = on, allow_page_locks = on, fillfactor = 90) on [primary]

go

create table fieldvalue ( id int identity (1,1) not null, customfieldid int not null, personid int not null, fieldvalue varchar(50)); alter table [dbo].[fieldvalue ] add together constraint [pk_fieldvalue] primary key clustered ( [id] asc )with (pad_index = off, statistics_norecompute = off, sort_in_tempdb = off, ignore_dup_key = off, online = off, allow_row_locks = on, allow_page_locks = on, fillfactor = 90) on [primary]

go

create table person ( id int identity (1,1) not null, personname varchar (50) not null); alter table [dbo].[person] add together constraint [pk_person] primary key clustered ( [id] asc )with (pad_index = off, statistics_norecompute = off, sort_in_tempdb = off, ignore_dup_key = off, online = off, allow_row_locks = on, allow_page_locks = on, fillfactor = 90) on [primary]

go

insert person (personname) values ('marc'); insert person (personname) values ('john'); insert customfield (fieldname, fieldordernumber) values ('bloodtype',1); insert customfield (fieldname, fieldordernumber) values ('eyecolour',2); insert fieldvalue (customfieldid , personid, fieldvalue) values (1,1, 'a+'); insert fieldvalue (customfieldid , personid, fieldvalue) values (1,2, 'o-'); insert fieldvalue (customfieldid , personid, fieldvalue) values (2,1, 'blue'); insert fieldvalue (customfieldid , personid, fieldvalue) values (2,2, 'hazel'); listfieldvalues (fieldordernumber, fieldname, personid, fieldvalue) ( select cf.fieldordernumber, cf.fieldname, fv.personid, fv.fieldvalue customfield cf left bring together fieldvalue fv on cf.id = fv.customfieldid ) select p.id, p.personname, lvf.fieldvalue column1, --bloodtype lvf2.fieldvalue column2 --eyecolour person p left bring together listfieldvalues lvf on p.id = lvf.personid , lvf.fieldordernumber =1 left bring together listfieldvalues lvf2 on p.id = lvf2.personid , lvf2.fieldordernumber = 2

first need create indexes on identity columns. create indexes on columns you're joining. these tips improve execution time.

c++ - Is std::random_shuffle reproducable across different compilers? -

c++ - Is std::random_shuffle reproducable across different compilers? -

i using std::random_shuffle function custom random number generator that, same seed, returns same sequence of random numbers across compilers.

however, i'm concerned std::random_shuffle may not utilize same algorithm between different compilers, , therefore, same seed, result won't same.

can rely on std::random_shuffle producing same output across different compilers same sequence of random numbers provided? if not, alternatives?

not using c++11 or boost.

from reading "25.3.12 random shuffle" in c++11 standard (the 1 have here) conclude strictly spoken guarantee can not made. requirement algorithm "that each possible permutation of elements has equal probability of appearance". not have swap elements front end back, example, , iterators random access iterators other order possible. (that said, i'd surprised if implementation wouldn't go first -> last, it's not guaranteed.)

i'm working on captcha class , i'm done, there 1 thing doesn't work

in file set form, start line:

include 'captcha.php'; $captcha = captcha::trycaptcha(2,4,'#000', '#ffffff');

and captch construct:

static $do_generate = true; function __construct($aantal_letters = 2, $aantal_cijfers = 4, $voorgrond = '#000000', $achtergond = '#ffffff') { session_start(); if (self::$do_generate == true) { $letters = substr(str_shuffle('abcdeghjklmnpqrstuvwxyz'),0 ,$aantal_letters); $cijfers = substr(str_shuffle('23456789'),0 ,$aantal_cijfers); $imgbreed = 18 * ($aantal_letters + $aantal_cijfers); $_session['imgbreed'] = $imgbreed; $_session['captcha'] = $letters . $cijfers; $_session['voorgrond'] = $this->hex2rgb($voorgrond); $_session['achtergond'] = $this->hex2rgb($achtergond); } }

so in other words set stuff in session if static var $do_generate == true

so when post form, captcha getting checked procesor.php

like this:

if (captcha::captcha_uitkomst() == true) { echo "great"; } else { echo "wrong";

}

and captcha function checks etered captcha code:

static function captcha_uitkomst() { if (strcmp($_session['captcha'], strtoupper(str_replace(' ', '', $_post['captcha-invoer']))) == 0) { homecoming true; } else { echo "test"; self::$do_generate = false; homecoming false; } }

if come in right captcha code, it's good, works echo great. if wrong echo wrong,

perfect, but.... when go form (hit backspace 1 history back) come in right captcha, regenerates new captcha.

in class: captcha_uitkomst see made self::do_generate false , echo 'test' works when it's false, (just checking)

what doing wrong

when nail "back", page reloaded. new captcha.

the premise of question fundamentally flawed, have randomly assumed shouldn't happen, whereas in reality entirely design.

it wouldn't effective captcha if repeatedly wrong go , seek again; bot start brute forcing and learning experience.

internet explorer 8 - JQuery file upload iframe method -

internet explorer 8 - JQuery file upload iframe method -

i'd set cross-domain file upload solution ie8 compatible. i've been using blueimp's jquery file upload plugin iframe transport option.

the upload works well, i'm not able results of upload server side. redirect alternative result.html file parsing seems solution, problem not have access server hosting form deploy html file. in case, there other way retrieve results of upload without deploying html file origin server?

inside javascript file can add together event listener (for non-jquery way see answer)

$(window).on('message', function(e){ var info = e.originalevent.data || e.originalevent.message; info = json.parse(data); //only if did json.stringify info sent //do need message send. });

next when upload done can either write page or redirect iframe page has content on it.

window.parent.postmessage('file upload done', '*');

if need send more info parent need json.stringify content first (old ie , ff don't allow objects, strings.)

window.parent.postmessage(json.stringify({'success': true, 'id': 1942}), '*');

here's code:

var server_port = process.env.openshift_nodejs_port || 8080 var server_ip_address = process.env.openshift_nodejs_ip || '127.0.0.1' var app = require('express')(); var server = require('http').server(app); var io = require('socket.io')(server); server.listen(server_port); app.get('/', function (req, res) { res.sendfile(__dirname + '/index.html'); }); io.on('connection', function (socket) { socket.emit('news', { hello: 'world' }); socket.on('my other event', function (data) { console.log(data); }); });

nothing special here, openshift's node variables used in right way.

server_ip_address should used. otherwise, uses default ip on openshift, 127.0.0.1. alter from:

server.listen(server_port);

to:

server.listen(server_port, server_ip_address);

logic of restore a binary tree based on travseral results, java -

can help explain logic of how draw original binary tree based on traversal results? know pre-order , in-order traversal, can't figure out start question. many in advance!

a binary tree has pre-order traversal result: a,b,d,h,i,e,f,c,g,k,j (treenodes) , same tree gives next in-order traversal: b,h,i,d,a,c,f,e,k,g,j. can draw tree structure?

you have combine both informations. start:

pre-order starts root => a. in-order can see nodes belong left , right subtree a:

left - b,h,i,d

right - c,f,e,k,g,j

from pre-order can see: left kid of b. in-order can see nodes belong left , right subtree of b:

left - none

right - h,i,d

continue...

the above trigger fired when there row insert operation on table datarequest. after row insert operation, take identity element generated after insert operation , utilize foreign key, , insert other values in different table. finally, utilize values both tables , create email sent.

i wasn't getting values other tables (e.g. @uf_linkedfiles), realized trigger beingness fired after insert in first table before insert in second table, no values available when sending email.

so how create sure trigger fired after sproc insert activities in multiple tables has completed transaction.

here table diagram -

instead of using trigger, have included email sending code in sproc rows beingness inserted.

this instead logs "undefined". have noticed however, removing loop's brackets this:

function range(num) { var holder = []; for(var = 0; <= num; i++) holder.push(i); homecoming holder; } console.log(range(40));

causes function work correctly, great except not understand why function works. can explain?

the return needs outside loop or leave function after first push

function range(num) { var holder = []; for(var = 0; <= num; i++) { holder.push(i); } homecoming holder; // must outside } console.log(range(40));

a single statement in loop not need brackets recommended have them anyway. here above single statement.

function range(num) { var holder = []; for(var = 0; <= num; i++) holder.push(i); homecoming holder; // must outside } console.log(range(40));

javascript arrays for-loop
