i have little knowledge iphone skd (don't know code objective c?). have far got table view working, , showing content on nib file once row clicked. i have elseif statements each row, telling them load nib file inside viewcontroller. however, 1 row causing problem, crases app. else if ([[array objectatindex:indexpath.row] isequal:@"ascii characters"]) { asciicharacters *asciicharacters = [[asciicharacters alloc] initwithnibname:@"ascii characters" bundle:nil]; [self.navigationcontroller pushviewcontroller:asciicharacters animated:yes]; [asciicharacters release]; } here image of debugger console: i don't do, there no errors displaying @ all. crashes app, if row clicked (both on simulator , iphone). think is't spaces in name. row has space. need space otherwise silly. :) i think need change line asciicharacters *asciicharacters = [[asciicharacters alloc] initwithnibname:@"ascii characters"

i wanted simple solution inter processes barrier. here solution: solution but totally lost mmap... first try, fails 1 out of ten times (segfault or deadlock). i understand problem comes synchronization issue, can't find it. found example set mmaped memory ( example ), not sure mmaped pthread_barrier. here extract of code: #define mmap_file "/tmp/mmapped_bigdft.bin" void init_barrier() { pthread_barrier_t *shared_mem_barrier; pthread_barrierattr_t barattr; pthread_barrierattr_setpshared(&barattr, pthread_process_shared); hbcast_fd = open(mmap_file, o_rdwr | o_creat | o_trunc, (mode_t)0600); result = lseek(hbcast_fd, sizeof(pthread_barrier_t)-1, seek_set); result = write(hbcast_fd, "", 1); shared_mem_barrier = (pthread_barrier_t*) mmap(0, sizeof(pthread_barrier_t), prot_read | prot_write, map_shared, hbcast_fd, 0); if (mpi_rank == 0) { int err = pthread_barrier_init(shared_mem_barrier, &barattr, host_size); } mpi_barri

my c# program uses com component via interop assembly. com component changes (methods added @ end of interface). i need build program in automated build , have interop assembly incrementing version number - can achieved using tlbimp pre-build step. the problem reference in project file set specific version (say 4.0.0.34) - 1 interop assembly had when reference added. once number incremented automated build , pre-build step done version number store in project file no longer matches number in assembly properties , get warning msb3245: not resolve reference. not locate assembly "interop.mycomcomponent, culture=neutral, version=4.0.0.34, processorarchitecture=msil". check make sure assembly exists on disk. if reference required code, may compilation errors. and then the type or namespace name 'mycomcomponent' not found (are missing using directive or assembly reference?) can somehow tell visual studio don't want store exact assembly version ins

can domain service can call domain entity, through service interface. for eg- : employee.fire() calling iemployee firing service. calling through interface not through concrete one. is possible ? though can without complilation error, don't think it's idea call domain service in domain entity. normally if action affects more 1 entities, put logic in service method. if fire action affects current employee, should encapsulate inside employee.fire(). else if affects multi employees, should put in service , application should invoke service.fire() instead of employee.file()

possible duplicate: how invoke static constructor reflection? i've got initialization code in static constructor of various classes. can't create instances, nor know types in advance. ensure classes loaded. i tried this: footype.typeinitializer.invoke (new object[0]); but got memberaccessexception: type initializer not callable. i'm assuming because cctor private? there way fix without changing architecture? edit: found workaround using runtimehelpers.runclassconstructor , way seems barely documented in msdn , i'm not sure if hack or reasonable, prod system way. i'm not sure why works, far reason (with skeet ) if have static class public static class statics1 { public static string value1 { get; set; } static statics1() { console.writeline("statics1 cctor"); value1 = "initialized 1"; } } the code: type statictype = typeof (statics1); statictype.typeinitializer.invoke(null)

it again sort of "how properly" question. sorry if annoyed. i've got understand ca 150 tlocs of c/c++ mixture. i've imported code in uml-tool "enterprise architect" , got messy chart. many structs , enums had anonymous names because of c-ish constructs: typedef struct/enum {...} mytype; in second run i've converted c++ form: struct/enum mytype{...}; got bunch of unrelated structs. unfortunately, enterprise architect doesn't resolve typedefs. e.g. no relations between a, b , c recognized: struct a; struct b; typedef *ptra; typedef list<b> blist; struct c{ ptra pa; blist lb; }; thanks throughout naming convention, able replace typedefs original type this: struct c{ pa; b lb; }; now importing source-code in "enterprise architect" gave nice diagram relations. of cause, code doesn't compile, , not same. changes in code require annoying conversion making "pseudo" code understandable ea again. therefore ques

i've got number of word: hello, poison, world, search, echo ... , i've got letters e, h, o need find words includes letters. search, echo e, h, o i can search way: words = %w[hello poison world search echo] matched = words.select |w| %w[e,h,o].all?{ |l| w =~ /#{l}/ } end the problem if letters o, o, o , or l, b, l search return true words open or boil , need search words includes 3 of o or 2 of l , 1 b upd: leters = "abc" words.select{ |w| w.count(letters) >= 3 } upd 2 bad solution, example: "lllllll".count("lua") #=> 5 are sure want regexp? strings support counting values in them, use feature. this: words = ["pool", "tool", "troll", "lot"] letters = "olo" #find how many of each letter need counts = {} letters.each { |v| counts[v] = letters.count(v) } #see if given work matches counts # accumulated above res = words.select |w| counts.keys.inject(true

i having trouble correctly implementing bentley-ottmann algorithm in c#. trying implement according pseudocode here . have posted main code below. assuming bst , priorityqueue classes implemented correctly, see problems code? there no errors, not intersection points found, some. guess there's error in else part of code (when current event intersection point). i'm not sure pseudocode means swapping position of 2 segments in bst. way fine? because in end, 2 aren't swapped in bst. can't change positions either, because break bst properties. also, right in assuming segments ordered in bst y -coordinate of left endpoint? another error i've noticed can't seem able track down point (0, 0) gets eventlist .

i have php-script i'd keep unchanged: $display = array( 'qdatetime', 'id', 'name', 'category', 'appsversion', 'osversion', ); $sql = sprintf(" select %s quincytrack qdatetime > (now() - interval '2 day') , qdatetime <= now()", join(', ', $display)); $sth = $pg->prepare($sql); $sth->execute($args); my problem qdatetime printed 2010-12-18 15:51:37 while need 2010-12-18 . know call to_char(qdatetime, 'yyyy-mm-dd') qdatetime , prefer find other way affect date output format... using postgresql 8.4.5 under centos 5.5 linux / 64 bit. thank you! alex a better approach relying on database date formatting rely on php this. echo date("y-m-d", strtotime($row['column'])); this both solves initial problem (of confusing join statement when building query), , gives lot more flexibility (eg, maybe later user can set pref

what best way express that, say, int field or parameter should never negative? the first thing comes mind annotation on type, case class foo(x: int @notnegative) . i'd have invent own annotation, , there wouldn't sort of compile-time checking or anything. is there better way? why not using separate data type? class natural private (val value: int) { require(value >= 0) def +(that:natural) = new natural(this.value + that.value) def *(that:natural) = new natural(this.value * that.value) def %(that:natural) = new natural(this.value % that.value) def |-|(that:natural) = natural.abs(this.value - that.value) //absolute difference override def tostring = value.tostring } object natural { implicit def nat2int(n:natural) = n.value def abs(n:int) = new natural(math.abs(n)) } usage: val = natural.abs(4711) val b = natural.abs(-42) val c = + b val d = b - // works due implicit conversion, d typed int println(a < b) //works due implici

i have js 'associative' array, array['serial_number'] = 'value' serial_number , value strings. e.g. array['20910930923'] = '20101102' i sorted value, works fine. let's object 'sorted'; now want access first key of 'sorted' array. how do it? can't think need iteration with for (var in sorted) and stop after ther first one... thanks edit: clarify, know js not support associative arrays (that's why put in high commas in title). javascript object properties specified have no order, much though many people wish different . if need ordering, abandon attempt use object , use array instead, either store name-value objects: var namevalues = [ {name: '20910930923', value: '20101102'}, {name: 'foo', value: 'bar'} ]; ... or ordered list of property names use existing object: var obj = { '20910930923': '20101102', 'foo': 'b

as understand it, order start-up files read bash shell on mac are... ~/.bash_profile ~/.bash_login ~/.profile ..and once 1 file in list found, contents of other ignored. that being said, there best practice of these files should 1 true bash start-up file? on 1 hand, if .bash_profile take precedence on other potential start-up file, should used, because can sure 100% of time info in start-up file being run. on other hand, if .profile file exists on mac systems default, , .bash_profile needs manually created, perhaps should used, , there never reason create .bash_profile file. thoughts? it depends on whether use shells other bash, , whether use bash-only features in profile. if use other sh-style shells (sh, ksh, zsh, etc not csh or tcsh), don't use bash-only features , want same setup no matter shell you're in, should use .profile. if want use bash-only features, use .bash_profile. if want use multiple shells use bash-only features, put common stu

i'm building large string list of items. each item generate string approximately 200 characters long (plus or minus 100%). will (noticeable) performance benefit using dim sb = new stringbuilder(averagecharactercount * items.count) instead of dim sb = new stringbuilder() even if specified capacity guess? starting in right ball-park save few reallocations/copies, note since doubling algorithm approach size pretty quickly. if within 100% 1 more reallocation/copy worst case, yes - starting approach some . but in many ways micro-optimisation; you're doing right way, unless our profiling shows still bottleneck (ad therefore need squeeze last few cycles out), forget , move on next thing.

i have simples question. have been trying learn grails own, , managed simple application using grails/gorm. 1 ) later, decided use mysql instead of gorm - needed configure 'datasource' , download driver. 2 )so if want use hibernate between both (grails , mysql) this: http://www.grails.org/doc/latest/guide/15.%20grails%20and%20hibernate.html , need make 'hibernate.cfg.xml' file, , specify mysql database url, user, pw etc .. , have map each class in grails mysql columns. so diference between 1) , 2) ? , hibernate does. give examples if possible ps. please correct me if said wrong, im kinda new this i think bit confused here. gorm not database, orm maps groovy classes database tables. uses hibernate under covers achieve (hibernate orm). the default database grails uses in-memory hsql db. if want use mysql instead of that, need change settings in conf/datasource.groovy. you don't need create hibernate xml files. part of documentation you'

is there guarantee, memory object aligned if create object of type in stack? union my_union { int value; char bytes[4]; }; if create char bytes[4] in stack , try cast integer there might alignment problem. can avoid problem creating in heap, however, there such guarantee union objects? logically there should be, confirm. thanks. well, depends on mean. if mean: will both int , char[4] members of union aligned may use them independently of each other? then yes. if mean: will int , char[4] members guaranteed aligned take same amount of space, may access individual bytes of int through char[4] ? then no. because sizeof(int) not guaranteed 4. if int s 2 bytes, knows 2 char elements correspond int in union (the standard doesn't specify)? if want use union access individual bytes of int , use this: union { int i; char c[sizeof(int)]; }; since each member same size, they're guaranteed occupy same space. believe want know about

i have windows app written in c (using gcc/mingw) works pretty except few ui problems. one, cannot progress bar update thread. in fact, can't ui stuff update. basically, have spawned thread processing, , thread attempt update progress bar in main thread. tried using postmessage() main hwnd, no luck though can other things open message boxes. however, it's unclear whether message box getting called within thread or on main thread. here's code: // in header/globally accessible hwnd wnd; // main application window hwnd progress_bar; //progress bar typedef struct { //to pass thread dword mainthreadid; hwnd mainhwnd; char *filename; } threadstuff; //callback function lresult callback wndproc(hwnd hwnd, uint msg, wparam wparam, lparam lparam){ switch (msg){ case wm_create:{ // create progress bar progress_bar = createwindowex( 0, progress_class, (lpctstr) null,

whats easy way can store password user inputs while still keeping password hidden? char password[9]; int i; printf("enter password: "); (i=0;i<9;i++) { password[i] = getch(); printf("*"); } (i=0;i<9;i++) printf("%c",password[i]); getch(); } i wanna store password can simple if (password[i] == root_password) proper password continues on. your problem appears you're not checking newline '\n' nor end-of-file. printf("enter password: "); char password[9]; int i; (i = 0; < sizeof password - 1; i++) { int c = getch(); if (c == '\n' || c == eof) break; } password[i] = c; printf("*"); } password[i] = '\0'; this way, password end being asciiz string, suitable printing puts , printf("%s", password) , or - crucially... if (strcmp(password, root_password)) == 0) your_wish_is_my_command(); note read @ 8 characte

i have jsp suppose load .swf file large in size takes of 7 sec load completely, hide loading , put javascript percentage loading bar swf file. as far know, can't build proper progress bar single file in javascript. progress bars web sites monitor load completion multiple images fake having access actual percentage of page being loaded (if 1 out of 10 images loaded, that's 10 percent, right?). alternatively, show animated gif, spinning wheel or else moves , not directly related size of file being loaded. add listener page's onload event, , hide gif when it's fired. ...or can still have nice progress bar, if don't in javascript: try reorganizing flash file instead! here tutorial on preloading single swf file .

let's enter registration form ending url: registration.php?accounttype=a form parsed on same page (registration.php). if user doesn't pass form validation taken registration.php error messages. see lost variable accounttype=a. question: can submit form validation , retain accounttype variable? i'm aware done using cookie. want further understanding. solution: although of answers below valid, went session variable , <form action="registration.php?<?php print 'accounttype=' . $_session['accounttype']; ?>" etc. help. you should use in form: <form action="registration.php?accounttype=a"> you should use in php: if ($validation_success) { header('sucess.php') } else { // don't anything. page(registration.php?accounttype=a) loads } i'm giving idea.
