my background of site responsive , works great.but i'm having issues images. want them "fixed" in same position background no matter resolution,. example re-sizing browser 990px 537px 990px 270px image never moved because width/height expand or contract depending on resolution of browser. good news figured css make width of image fluid background! bad news if make height 100% or 14%, height looks same. true need specificity height? why not width? how? #block-imageblock-4{ width:26%; height:14%; margin-top:7%; margin-bottom:1%; margin-left:37%; margin-right:36.5%; max-width:100%; max-height:100%; } so question how show image in same position on screen if resolution large or small? please provide example , not link. said figured out make width of image fluid, not height if have better way please share. i'm using drupal build site fyi. <---------------------------------------------edit------------------------------

i use macros concatenate strings, such as: #define str1 "first" #define str2 "second" #define strcat(a, b) b which having strcat(str1 , str2 ) produces "firstsecond" . somewhere else have strings associated enums in way: enum class myenum { value1, value2 } const char* myenumstring[] = { "value1string", "value2string" } now following not work: strcat(str1, myenumstring[(int)myenum::value1]) i wondering whether possible build macro concatenate #define d string literal const char* ? otherwise, guess i'll without macro, e.g. in way (but maybe have better way): std::string s = std::string(str1) + myenumstring[(int)myenum::value1]; the macro works on string literals, i.e. sequence of characters enclosed in double quotes. reason macro works c++ standard treats adjacent string literals single string literal. in other words, there no difference compiler if write "quick" "brown&

i need sort 2 dimension array in ascending order ,i write code in c# sort array sort each line in array not 2 dimension array , how can sort 2 dimension array double[,] test_descriptor = new double[3, 3]; double tempr; test_descriptor[0,0]=7; test_descriptor[1, 0] = 7; test_descriptor[2, 0] = 5; test_descriptor[0, 1] = 3; test_descriptor[1, 1] = 0; test_descriptor[2, 1] = 2; test_descriptor[0, 2] = 1; test_descriptor[1, 2] = 9; test_descriptor[2, 2] = 1; (int = 0; < test_descriptor.getlength(0); i++) // array sorting { (int j = test_descriptor.getlength(1) - 1; j > 0; j--) { (int k = 0; k < j; k++) { if (test_descriptor[i, k] > test_descriptor[i, k + 1]) { tempr = test_descriptor[i, k]; test_descriptor[i, k] = test_des

i trying figure out how memorycache should used in order avoid getting out of memory exceptions. come asp.net background cache manages it's own memory usage expect memorycache same. not appear case illustrated in bellow test program made: class program { static void main(string[] args) { var cache = new memorycache("cache"); (int = 0; < 100000; i++) { addtocache(cache, i); } console.readline(); } private static void addtocache(memorycache cache, int i) { var key = "file:" + i; var contents = system.io.file.readallbytes("file.txt"); var policy = new cacheitempolicy { slidingexpiration = timespan.fromhours(12) }; policy.changemonitors.add( new hostfilechangemonitor( new[] { path.getfullpath("file.txt") } .tolist())); cache.add(key, conte

what maximum size of static array, , dynamic array? think there no limit dynamic array why static arrays have limited size? unhandled exception @ 0x011164a7 in stackoverflow.exe: 0xc00000fd: stack overflow (parameters: 0x00000000, 0x00482000) this looks more runtime error. more precisely - stack overflow. in places size of array limited available memory. however, limit on stack allocated objects more severe. default, it's 1mb on windows , 8mb on linux. looks array , other data on stack taking more space limit. there few ways avoid error: make array static or declare @ top level of module. way allocated in .bss segment instead of stack. use malloc / new explicitly allocate array on heap. use c++ collections such std::vector instead of arrays. increase stack size limit. on linux can done ulimit -s unlimited

the mmread function used work until yesterday! since i've been getting error: error using mmread (line 435) dimensions not match data size. little data. has ever got same problem? should do? working on windows 7 professional n, 64bit, , matlab r2012b. code correct, cause works fine on virtual machine! i tried uninstalled installed programs (java, video tools , others) still not working! link function http://www.mathworks.com/matlabcentral/fileexchange/8028-mmread

i started learn javascript , have prior experience in server side languages such php. issue i'm having cannot use variables defined outside of function inside function. have copy variable function in order code work. post example below. var first = document.getelementbyid("first"); var second = document.getelementbyid("second"); function add () { alert(number(first.value) + number(second.value)); } most problem script being executed when page still being loaded, , before "first" , "second" elements have been created. accessing variables works fine. happen initialized "undefined" @ time created. moving variables inside function means aren't initialized until function called, after page has been loaded.

using bytebuffer, can convert string byte array: val x = bytebuffer.allocate(10).put("hello".getbytes()).array() > array[byte] = array(104, 101, 108, 108, 111, 0, 0, 0, 0, 0) when converting byte array string, can use new string(x) . however, string becomes hello????? , , need trim down byte array before converting string. how can that? i use code trim down zeros, wonder if there simpler way. def bytearraytostring(x: array[byte]) = { val loc = x.indexof(0) if (-1 == loc) new string(x) else if (0 == loc) "" else new string(x.slice(0,loc)) } assuming 0: byte trailing value, then implicit class richtostring(val x: java.nio.bytebuffer) extends anyval { def bytearraytostring() = new string( x.array.takewhile(_ != 0), "utf-8" ) } hence for val x = bytebuffer.allocate(10).put("hello".getbytes()) x.bytearraytostring res: string = hello

i'm beginner in ruby on rails. dropped table. have files in db/migrate folder. how can table migrate files? the ideal way this, using rake db:setup this recreate database , load schema development database. every migration rails keeps current state of database in schema.rb (or structure.sql ), , uses efficiently recreate last state. if have pending migrations, have rake db:migrate , take more time, since redo every step before. also note in cases not possible run migrations start again, , imho not intention of migrations.

i'm trying understand how should read python documentation, example given: string.lstrip(s[, chars]) how should read that? know brackets means optional, 's', mean? there page explains how documentation written? it's not explictly defined in documentation, in string.lstrip(s[, chars]) string python module, not string (e.g. can't "abc" ). the parameter s string (e.g. can "abc" ) want strip. it's mandatory, not optional. the bracket-enclosed parameter optional , string , characters stripped string. some examples of how call function are: import string print string.lstrip("abc", "a") # "bc" print string.lstrip(" abc") # "abc" note: don't confuse "abc".lstrip() . different functions identical results. also, read @user2357112's comment. edit: on ide i've tested , shows s on docs (pressing f2 ): def lstrip found at: string def lstrip(s, c

i´m getting desperate when trying create second preference activity of app. have implemented sharedpreferences, works pretty good, trying create second preference activity work on specific activity, cannot make work properly. happening that, no matter color select, giving me "default value" = 1, if preference file checking not exist. here code of preferenceactivity: public class preferenciasgrafica extends preferenceactivity { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); addpreferencesfromresource(r.xml.preferencias_grafica); } public void onbackpressed(){ //preferencias //preferencemanager.getdefaultsharedpreferences(this);//carga archivo preferencias sharedpreferences appprefs2 =this.getpreferences(mode_private); int colore=integer.parseint(appprefs2.getstring("color","1"));//pasa samples las prefer. elegidas //startactivi

is there way fire custom keyup / keydown event on corewindow ? for example, take following event: http://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.core.corewindow.keyup.aspx . my application uses corewindow::keyup , corewindow::keydown handle events. trying test correct delegates being attached , called when event happens. note can't call delegate function directly since not test fact delegate attached event. i looking answer similar https://stackoverflow.com/a/3977396/756356 . i doubt that's possible because sounds possibly interfering sandbox concept of modern apps. maybe insert layer between corewindow , handlers , bubble events through layer make possible raise proxy events. recommend against though since adds code don't need.

i have rather simple (i think) question @ hand. example tables , result need provided below (in reality tables containt more columns , data, jest left relevant). there query returns need. however, dont rather crude way in works (i dont subqueries in general). question is, how can rewrite query automatically react more columns appearing in table2 in future? right if "z" column added table2, need modify each query in code , add 1 more relevant subquery. want select read entire content of table2 , translate id numbers corresponding strings table1. table1 ----------------- id |x | ----------------- 567 |aaa | 345 |bbb | 341 |ccc | 827 |ddd | 632 |eee | 503 |fff | 945 |ggg | 234 |hhh | 764 |iii | 123 |jjj | ----------------- table2 ------------------------- id |x |y | ------------------------- 1 |123 |341 | 2 |567 |632 | 3 |345 |945 | 4

how set background color of piece of text in pdf document using itextsharp without taking form field? the answer in this post uses formfield , according me overkill , long-winded way simple. is there simple way of coloring background of piece of text? you can use method setbackground available in chunk class. there 2 variations of method: 1 takes default padding , 1 allows change padding. if use ongenerictag() method on chunk , can draw custom background (and more). instance: you'd use ongenerictag() if want draw rectangle rounded corners. see answer duplicate question draw rectangle @ *current position* , position coordinates

i understand, in mac os x, system-wide os keeps tracks of list of recent opened items (files) (click apple icon, , click "recent items". obtain list can used other purposes. possible have api query such items or has been stored in file locally (if so, location)? thanks it's stored in: /users/username/library/preferences/com.apple.recentitems.plist it's binary property list file, can view contents in xcode, or use /usr/libexec/plistbuddy in terminal, or use property list api's. here's bash script dump recent documents in alpha order. doccount=$(/usr/libexec/plistbuddy -c "print recentdocuments:maxamount" \ ~/library/preferences/com.apple.recentitems.plist) (( i=0; i<doccount; i++ )); /usr/libexec/plistbuddy -c "print recentdocuments:customlistitems:$i:name" \ ~/library/preferences/com.apple.recentitems.plist done | sort

is there way make poco::domparser work std::wstring ? i build pocoxml lib defined xml_unicode , xml_unicode_wchar_t . i'm trying compile code this: poco::xml::domparser parser; std::wstring xml = getxml(); //init string xml document // cannot compile, cause parsestring wants std::string // not wstring poco::autoptr<poco::xml::document> document = parser.parsestring(xml); poco::xml::saxparser can parse std::wstring , poco::xml::domparser use saxparser build document. have no idea why cannot pass std::wstring parsestring. maybe cannot use parsestring, there way parse std::wstring domparser? you should able use std::wstring on windows xml_unicode_wchar_t defined. on posix platforms, you'll have make sure wchar_t 2 bytes wide (check __sizeof_wchar_t__ define). practice use xmlstring, appropriately defined std::basic_string , based on xml_unicode_wchar_t define. there problem prevents poco::xml compilation xml_unicode_wchar_t , though. github i

in code (hypothetical) i'd use getorcreate function. pass parameters , either new entity or existing entity database, if such entity exists. from 1 point of view wrong approach, because function should not more 1 thing. point of view single operation, not have proper word in english , can reduce duplicities in code. so using approach or bad practice? , why? it's function. instance of class. it doesn't matter outside world how function works internally. public object getobject(int key) { object object = getobjectfromdatabase(key); if (object == null) { object = createobject(key); writeobjecttodatabase(key, object); } return object; } every method has 1 function. edited add: people @ methods inside out. that's need when you're writing code method. recognized getobject method had several things object. however, when you're naming method, @ method outside. why getobject m

in module "menu accordeon ck" there field "item id opened default", id, can specify want make menu open default. need specify more 1 such id. example: 108, 129, 30, 165 realistically, can run 1 id. how more? this code specifies id of menu items . "defaultopenedid : '" . $params->get('defaultopenedid') . "'," you can specify 1 itemid because these ids represent menu items , settings , security them. in other words, there's isn't practical way open more 1 menut item (itemid). think may need revisit you're trying accomplish because seems highly unlikely want open more 1 menu item. it appear menu accordion ck giving ability open page, use particular menu itemid you'll modules , template settings you've specified menu item used.

i can't seem find assertion in phpunit tests if string contained somewhere in string. trying this: public function testrecipe() { $plaintext = get_bread_recipe(); $this->assertstringcontains('flour', $plaintext); } what real assertion put instead of assertstringcontains ? prefer not having worry regex in case because there absolutely no need it. it's simple there must have overlooked, can't figure out! funny enough there assertstringstartswith() , assertstringendswith() ! update: know strpos() !== false used i'm looking cleaner. if use vanilla php functions anyway what's whole point assertions then... as tell assertcontains checking array contains value. looking see if string contains substring, simplest query use assertregexp() $this->assertregexp('/flour/', $plaintext); you need add delimiters. if want have assertstringcontains assertion, can extend phpunit_framework_testcase , create own. upd
