i'm interested in nuts , boltw of c++ , wondered changes when object instantiated. i'm particularly interested if functions added memory, if there runtime or if never stored in memory @ all. if direct me site on of core bolts of c , c++, i'd love too. thanks, jo a common case is: memory allocated calling operator new . function in memory, it's needed lot. the constructor of class called. code in memory. if not, call function page-faults. os notes, , loads appropriate page executable ram. tells os retry. ( 2a. ctor arranges virtual functions callable - writing vtable pointer ) chances page constructor contains other members of class. can called too. if on page, calling them may cause page fault , load. if compiler put vtable on different page, use of vtable may cause page fault. the advantage of such load-on-demand mechanism os can avoid loading code class cprinter if user never intends print document.

i have tabhost 4 tabs. need selected tab activity available on stack. when user changes tab, how finish activity under previous tab. tried following code. here showing code first tab. similar remaining tabs: spec = tabhost.newtabspec("tab1").setindicator("tab1", res.getdrawable(r.drawable.ic_tab_tab1)) .setcontent(new intent(this, tab1.class) .addflags(intent.flag_activity_no_history | intent.flag_activity_clear_top)); but above code deleting tab1 activity on stack/heap when user comes again tab not when user changes new tab. i've had @ this, reason this? how know what's on stack? depending on ondestroy() or something? i haven't got full answer can see tab active: let class implement ontabchangelistener public class yourclass extends tabactivity implements ontabchangelistener { @override protected void oncreate(bundle savedinstancestate) { // load normal objects tabhost // ma...

i running 2 processes,process opened process b using following example: createprocesshandle = createprocess( text("c:\\users\jamie\\documents\\application\\debug\\processa.exe"), text(""), null, null, false, 0, null, null, &startupinfo, &process_information ); as can see process reliant on path given it, problem have if change location of processa.exe (such backup/duplicate) it's tiresome process keep recoding path. want able make run no matter without having recode path manually. can suggest solution this? edit: not have access path environment variable there 2 options. use relative path. put directory in path environment variable. in case, use lpcommandline, not lpapplicationname.

okay, when draggable, given class .ui-draggable , when disabled being draggable .ui-draggable-disabled i want select items draggable. i'm using following selector, doesn't seem work. disabled draggable items still doing on hover. ideas why? $('.ui-draggable').not('.ui-draggable-disabled').hover(function() { // rest of code thanks try: // selector means "doesn't have", ':not(:has(selector))' $(".ui-draggable:not(:has(.ui-draggable-disabled))").hover(function() { ... or: $('.ui-draggable').not(':has(.ui-draggable-disabled)').hover(function() { or test presence of disabled class within hover mouseover/mouseout functions: $(".ui-draggable").hover(function() { if(!$(this).hasclass("ui-draggable-disabled")) { // stuff } }, function() { if(!$(this).hasclass("ui-draggable-disabled")) { // stuff } });

im having problem setting section headers in uitableview, simple cant work out. instead of displaying different headers different sections displays same header each section help me please :) - (nsinteger)numberofsectionsintableview:(uitableview *)tableview { worldcupappdelegate *appdelegate = [uiapplication sharedapplication].delegate; return [appdelegate.matchfixtures count]; } - (nsstring *)tableview:(uitableview *)tableview titleforheaderinsection:(nsinteger)section { worldcupappdelegate *appdelegate = [uiapplication sharedapplication].delegate; fixtures *fixtures = [appdelegate.matchfixtures objectatindex:section]; return fixtures.matchdate; } your original code looks okay. i'm betting appdelegate.matchfixtures doesn't contain data think does. modify code this: - (nsinteger)numberofsectionsintableview:(uitableview *)tableview { worldcupappdelegate *appdelegate = [uiapplication sharedapplication].delegate; nslog(@...

i'm trying add additional cell custom content last cell in tableview, without altering dictionary creates other content of table. think place add in cellforrowatindexpath rather adding 1 numberofrowsinsection , crashes if do. i cellcount dictionary creates data table, in cellforrowatindexpath , have: if (indexpath.row == cellcount) { ... stuff goes here return cell; } of course, never gets called. if if (indexpath.row == cellcount -1) overwrites last cell content. i can work if add blank entry xml populating dictionary, that's ugly. example code neat! the problem here tableviews designed , accurately display contents of data-model , you've decided don't want that. you're fighting api. the straight forward way put check in numberofrowsinsection such adds 1 row count when want display input row. in cellforrowatindexpath: need check if table view asking input row , return appropriate type of...

i trying encapsulate code using module pattern. problem can't reference it. following error message: 'plannertab.getconfig' null or not object line: 14 char: 5 code: 0 code /* document ready */ $(function () { /* config */ var config = plannertab.getconfig; }); /* module */ var plannertab = (function () { var config = { tableid: '#plannertable' }; return { getconfig: config }; })(); you're victim of automatic semicolon insertion. this: return { getconfig: config }; should written like: return { getconfig: config };

i've been bothered "characteristics": when use button leave app, can tell ondestroy() called, next time run app, static members of activity class still retain values. see code below: public class helloandroid extends activity { private static int mvalue; // static member here public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); textview tv = new textview(this); tv.settext((mvalue != 0) ? ("left-over value = " + mvalue) : "this new instance"); setcontentview(tv); } public void ondestroy() { super.ondestroy(); mvalue++; } } the above code displays left-over value in mvalue, , increments when session ends know sure ondestroy() called. i found useful answer on forum, , understand in above code mvalue class member, instead of instance member. isn't true that, in particular case, have 1 single helloandroid activity, , when dies, cleaned up, , next time come back, starts o...

i'm building event registration site. given event, we'll have handful of items choose from. have table these items. each event might have special options users. example, 1 of events new users buy item not available other users. may not apply events. other events might have other restriction on items. checking programmatically on application side. though, set column containing flag in items table. don't find feasible because condition may apply 1 particular event. don't want future items have column. approach take in such situation? should create special "restrictions" table , join? how handle on application side? yes, going need additional table list of items have special rules. sounds 'special options' idea still evolving, it's know whether think of containing 'restrictions' or 'bonuses' and of course you'll need table maps items particular groups of users. general advice in sort of situation: sho...

i've heard should possible lossless rotation on jpeg image. means rotation in frequency domain without idct. i've tried google haven't found anything. bring light this? what mean lossless don't lose additional information in rotation. , of course that's possible when rotating multiples of 90 degrees. you not need idct image rotate losslessly (note lossless rotation raster images possible angles multiples of 90 degrees). the following steps achieve transposition of image, in dct domain: transpose elements of each dct block transpose positions of each dct block i'm going assume can following: grab raw dct coefficients jpeg image (if not, see here ) write coefficients file (if want save rotated image) i can't show full code, because it's quite involved, here's bit idct image (note idct display purposes only ): size s = coeff.size(); mat result = cv::mat::zeros(s.height, s.width, cv_8uc1); (int = 0; < s.height - dcts...

the size of shared memory ("local memory" in opencl terms) 16 kib on nvidia gpus of today. have application in need create array has 10,000 integers. amount of memory need fit 10,000 integers = 10,000 * 4b = 40kb. how can work around this? is there gpu has more 16 kib of shared memory ? think of shared memory explicitly managed cache. need store array in global memory , cache parts of in shared memory needed, either making multiple passes or other scheme minimises number of loads , stores to/from global memory. how implement depend on algorithm - if can give details of trying implement may more concrete suggestions. one last point - aware shared memory shared between threads in block - have way less 16 kb per thread, unless have single data structure common threads in block.

i applying sha-512 on data. theoretically/practically possible derive sha-256 hash original data sha-512 hash? since have different number of rounds, different size of internal state , different block-size i'm pretty sure result of sha-256 , sha-512 different can't derive either of them other. but if paranoid append/prepend different data different hash-functions. i.e. calculate sha-256("a"+data+"b") , sha-512("d"+data+"e") (of course longer strings instead of abcd). the possibility see if set of possible input values small brute-force possible values until hit known hash , calculate other hash. if conditions attacker can reverse known hash, can calculate other hash.

i'm having trouble cross-domain policy. i'm using as3 loader fetch image; i'm making load policy file, : var ploader : loader = new loader(); var pcontext : loadercontext = new loadercontext(); pcontext.checkpolicyfile = true; ploader.load(new urlrequest(surl), pcontext); this works fine long image directly accessible; however , when server sends redirect, loader follows loses checkpolicyfile flag, resulting in securityexception - is, doesn't check cross-domain policy of redirected url. i've found solution here ( http://www.stevensacks.net/2008/12/23/solution-as3-security-error-2122-with-300-redirects ) looks fragile (that is, looks fail if there's more 1 redirect). correct way of doing this? edit : best solution use new loader if accessing content throws securityexception , loaded url different 1 requested originally... works, feels hack. you can try this: http://www.arpitonline.com/blog/2008/06/17/debugging-crossdomain-issue...

my problem have 2 js file (1.js, 2.js), in both has same functionality , methods(or copy of file). want call function (like _finish() ) 1 js(1.js) file js file(2.js) file. can give solution. i agree jandy. in case must use namespaces. example, if have script 1 defining variable a , second script defining it's own variable a , when 2 scripts put together, last script executed browser overwrites a variable : //script 1 var = 'script 1 value'; // ... //script2 var = 'script 2 value'; // ... alert(a); when execute above example, you'll see second script has redefined a variable. so, best way without having name conflicts using namespaces: //script 1 script1namespace.a = 'script 1 value'; // ... //script2 script2namespace.a = 'script 2 value'; // ... alert(script1namespace.a); alert(script2namespace.a);

as titles says. dependent property in silverlight/wpf. there no such thing in c#. guess talking dependency properties , wpf concept. see dependent properties , msdn .
