i'm writing if statement in python lot of or conditions. there elegant way list, within in condition rather looping through list? in other words, prettier following: if foo == 'a' or foo == 'b' or foo == 'c' or foo == 'd': i've taken python, , language has me wanting write better. if foo in ('a', 'b', 'c', 'd'): #... i note answer wrong several reasons: you should remove parentheses.. python need outer ones , takes room. you're using assignment operator, not equality operator (=, not ==) what meant write foo == 'a' or foo == 'b' or ..., wrote wasn't quite correct.

after user has provided me oauth credentials, allow them post message group of friends. say have created list of 10 friends , called "my soccer buddies", want able allow them post message list "my soccer buddies" within web application using graph api. how ? looking @ http://developers.facebook.com/docs/reference/api/post seems possible providing "to" parameter in http://developers.facebook.com/docs/api#publishing says must post /profile_id/feed - desc: - write given profile's feed/wall - args: - message, picture, link, name, caption, description, source note param not available in args above. so how done? also: reccomended way web app using graph api allow user send send message 10 of friends? it not possible. new groups feature provides access via graph api , looked alternative.

so, i'm trying troubleshoot error, , being able see files synced given server since date go long way toward helping me figure things out. feel there should way through "p4 have", can't figure out or find in documentation. important: not looking files submitted p4 during time. want see files synced server. thanks! "p4 have" indeed tell files sync'd workspace. won't tell when sync'd. sounds 1 of questions if told little bit why thought wanted know information, suggest different technique, address problem.

i have confusion concept of inheritance in c++, suppose have class named computer , publicly inherit class named laptop computer class. when create object of class laptop in main function happens in memory? please explain. i'm assuming laptop inherits computer, , explaining happens in general; implementation details of c++ (for optimization reasons) may differ general explanation. logically, laptop class definition has pointer computer class definition. instance of laptop class has pointer laptop class definition (in c++, reference array of function pointers class methods). when laptop object receives message, first looks in own method table corresponding function. if not there, follows inheritance pointer , looks in method table computer class. now, in c++, of happens in compilation phase, in particular believe method table flattened , calls can statically bound shortcut.

if want load image should use css background not in ? think difference show in low speed internet connection. i saw many articles related css preloading using images in css background. http://perishablepress.com/press/2008/04/15/pure-css-better-image-preloading-without-javascript/ http://perishablepress.com/press/2007/07/22/css-throwdown-preload-images-without-javascript/ http://divitodesign.com/css/create-an-image-pre-loader-with-css-only/ it's order in things happen. browsers @ liberty begin processing things possible, so, in average page css defined in head, able start requesting , recieving images css before able body of document. so in short, answer yes. but... bear in mind doesn't load images faster. doing changing load order, not absolute speed. images still take same amount of time load. if move out of body , css in head, still left priority decisions ones load first. come full circle. can't make faser else.

basically, used make application instance singleton. i wish know, how works internally , how os manage ? it creates system-wide object. how os manages consealed implementation detail, can use mutex trough os-supplied functions (like releasemutex() example).

i trying create class-inheritance design products. there base table contains common fields. each product type there separate table containing fields product type only so in order data product need join base table whatever table correlates product_type listed in base table. there way make query join on table dynamically? here query try illustrate trying do: select * product_base b inner join <value of b.product_type> t on b.product_base_id = t.product_base_id b.product_base_id = :base_id is there way this? no, there's no way this. table name must known @ time of parsing query, parser can tell if table exists, , contains columns reference. optimizer needs know table , indexes, can come plan of indexes use. what you're asking table determined during execution, based on data found row-by-row. there's no way rdbms know @ parse-time all data values correspond real tables. there's no reason implement class table inheritance . cti s...

i've got following mysql query / subquery: select id, user_id, another_id, myvalue, created, modified, ( select id users_values parentusersvalue parentusersvalue.user_id = usersvalue.user_id , parentusersvalue.another_id = usersvalue.another_id , parentusersvalue.id < usersvalue.id order id desc limit 1 ) old_id users_values usersvalue created >= '2009-12-20' , created <= '2010-01-21' , user_id = 9917 , another_id = 23 given criteria listed, result subquery (old_id) should null (no matches found in table). instead of mysql returning null, seems drop "where parentusersvalue.user_id = usersvalue.user_id" clause , pick first value matches other 2 fields. mysql bug, or reason expected behavior? update: create table users_values ( id int(11) not null auto_increment, user_id int(11) default null, another_id int(11) default null, myvalue double default null, created datetime default null,...

i want know how many lines have in file. how can in simple way (i mean, not go through on over file , count each line)? there command that? well: int lines = file.readalllines(path).length; is simple, not efficient huge text files. i'd use textreader in cases, avoid excessive buffering: int lines = 0; using (textreader reader = file.opentext(path)) { while (reader.readline() != null) { lines++; } }

i have database tables each entity in system. e.g. persontable has columns personid, name, homestateid. there table 'reference data' (i.e. states, countries, currencies, etc.) data used fill drop down list boxes. reference table used persontable's homestateid foreign key reference table. in c# application have interfaces , classes defined entity. e.g. personimplementationclass : ipersoninterface. reason having interfaces each entity because actual entity class store data differently depending on 3rd party product may change. the question is, should interface have properties name, homestateid, , homestatename (which retrieved reference table). or should interface not expose structure of database, i.e. not have homestateid, , have name, homestatename? i'd you're on right track when thinking property names! model classes in real world. forget database patterns , naming conventions of stateid , foreign keys in general. person has city, not cityi...

i have jqgrid , on button click want send 2 column values instead of sending whole values...how can achieve using getrowdata ....any suggestion appreciated.. thanks! probably method getcol can halt mostly. if 1 columns want send column id ( key:true ) can receive data need 1 call: var mydata = $('#list').jqgrid('getcol', 'column name 1', true); if no columns has key:true in column definition should make 2 calls: var mydata1 = $('#list').jqgrid('getcol', 'column name 1'); var mydata2 = $('#list').jqgrid('getcol', 'column name 2'); then can combine data or set there separate 2 parameters: $.ajax({ type: "post", url: "/cpsb/internalorderlist.do", data : { jggriddata1: json.stringify(mydata1), jggriddata2: json.stringify(mydata2) }, datatype:"json", contenttype: "application/json; charset=utf-8", success: funct...

i've started learning prolog , wondering theoretical difference sql language. for example: both declarative languages both support fact-driven knowledge database both support question-styled data-retrieving both support functional dependencies any more common points? notable differences? most of (earlier) answers here reflection of fact people not know sql (its implementation of relational calculus) or means (that it's form of predicate logic). following statements true of both prolog , sql: they both logic-driven they can both store, express , use relations (logical relationships in prolog) they can both store , express complex logical conditions they both have facts(data in sql) , can derive conclusions facts they both have queries, in fact mean same thing they both have data(facts in prolog) , use them similarly they both programming languages they both turing-complete (though difficult access in both of them) etc, etc.. generally, peop...

how can use eval in groovy evaluate following string: {key1=keyval, key2=[listitem1, listitem2], key3=keyval2} all list items , keyval string. doing eval.me("{key1=keyval, key2=[listitem1, listitem2], key3=keyval2}") giving me following error: ambiguous expression either parameterless closure expression or isolated open code block; solution: add explicit closure parameter list, e.g. {it -> ...}, or force treated open block giving label, e.g. l:{...} at i want hashmap you can parse string translating of characters, , writing own binding return variable names when groovy tries them up, so: class evaluator extends binding { def parse( s ) { groovyshell shell = new groovyshell( ); shell.evaluate( s ) } object getvariable( string name ) { name } } def instr = '{key1=keyval, key2=[listitem1, listitem2], key3=keyval2}' def inobj = new evaluator().parse( instr.tr( '{}=', '[]:' ) ) println inobj but very britt...

according msdn there overload observablecollection constructor can pass ienumerable. according short msdn page make "copy" of ienumerable. how determine how behave? "copy" totally independent of original or changes made ienumerable (such linq query) reflected automatically in observablecollection? msdn page this constructor walks through items in ienumerable , adds each 1 observablecollection . once finished new observablecollection has nothing more ienumerable (except if dealing collection of reference types observablecollection hold references same objects supplied ienumerable ).

this should simple one. using program has themes defined in web.config file. want turn these off subdirectory. i copied web.config subdirectory , tried removing theme attribute pages element on web.config didn't me anywhere. got bunch of errors elements apparently not allowed in non-root web.config files removed of elements, still getting same error. i tried adding enabletheming="false" in aspx page header, thing defines language=c# , etc., didn't work either. so if can tell me tested, confirmed way make work, appreciate that. using .net framework 2.0 on server 2003. got basic web.config: <?xml version="1.0"?> <configuration> <system.web> <pages theme="" /> </system.web> </configuration>

i hav datetimepicker control format have set custom dd/mm/yyyy (with no time). store date in database varchar , not datetime because giving sort of error regarding invalid datetime format. use datagrid display records database. thing need retrive date datagrid (when user selects particular date cell in datagrid) , want display on datetimepicker control (so user can edit it). using following code so: dtdate.value = convert.todatetime(dgdetails.selectedcells[1].formattedvalue); the error getting "string not recognized valid datetime". dtdate datetimepicker control, dgdetails datagrid , selectedcells[1] cell containing date. you shouldn't have reacted error changing type in database inappropriately - if you're trying store dates, should use closest available type in database. the problem querying/updating/inserting putting value directly in sql instead of using parameterized query - right solution use parameterized query. you've done same thing da...

i have been using touches began track many 8 touches, , each triggers event. these touches can occur @ same time, or staggered. - (void)touchesbegan:(nsset *)touches withevent:(uievent *)event { nslog(@"touch began"); nsset *alltouches = [event alltouches]; (int i=0; i<alltouches.count; i++) { uitouch *touch = [[alltouches allobjects] objectatindex:i]; if (/*touch inside button in question*/) { //trigger event. } } } that code works multitouch, , has no problems, except: (see if can guess) due way alltouches works, literally gets of touches. because of this, loops through of touches active when user starts touch, , triggers event of 1 of buttons twice. ex: johnny pressing button 1. event 1 occurs. johnny leaves finger on button 1, , presses button 2. event 2 occurs, button 1 still part of alltouches, , so, event 1 triggered again. so here's question: how new touch? the same touch object ret...

the following jquery works fine in firefox me, failed in ie6: $("<map></map>").attr("name",somevar).appendto("#someelement"); the problem map element never gets name attribute generated can prove calling alert($("#someelement").html()); , fact image associated doesn't have links if use instead, works fine: $("<map name='" + somevar + "'></map>").appendto("#someelement"); i'm happy use second line of code, wondering if else has had problem...or explanation of why didn't work (i'm wondering specific name attribute)...

thanks in advance taking time read this. apologies verbose. explains problem. stripped code demonstrating issue included. i'm having issue pyqt4 signal/slots. while can make work fine if writing in single file, can't make things work if of functions wish use moved sub-directories/classes. i've looked through python bindings document can see how works when using single file. trying this: main.py file in root dir contains mainwindow __init_ _ code. this file imports number of widgets. each widget stored in own sub-directory. sub-directories contain __init__.py file. these sub-directories inside of directory called 'bin', in root dir some of these widgets need have signal/slot links between them fall down. so file structure is: - main.py - bin/texteditor/__init__.py - bin/texteditor/plugin.py - bin/logwindow/__init__.py - bin/logwindow/plugin.py the following code shows problem. code creates basic main window contains central qtextedit() wid...
