i know have seen before. can't remember if c4mvc template demo or input builder thing! need know how can use convention of camelcasing view model properties , having "camelcasedproperty" rendered in label "camel cased property". should handled create new view wizard rather programatically handling this. i don't think want possible in vanilla asp.net mvc 2. in asp.net mvc 2 need decorate model displayname attribute text want , auto generated wizard use labelfor output label property. eg: class mymodel() { [displayname("your property name")] public string yourpropertyname { get; set; } } then in view: <%= html.labelfor(m => m.yourpropertyname) %> if saw demo of being done other way have been mvccontrib project inputbuilders . here direct link part of project think referring to: http://www.lostechies.com/blogs/hex/archive/2009/06/09/opinionated-input-builders-for-asp-net-mvc-part-2-html-layout-for-the-la...

i have whole bunch of large html documents tables of data inside , i'm looking write script can process html file, isolate tags , contents, concatenate rows within tables 1 large data table. loop through rows , columns of new large table. after research i've started trying out php's domdocument class parse html wanted know, best way this? this i've got far... $dom = new domdocument(); $dom->preservewhitespace = false; @$dom->loadhtmlfile('exrate.html'); $tables = $dom->getelementsbytagname('table'); how chop out other tables , contents? i'd remove first table since it's table of contents. loop through table rows , build them 1 large table. anyone got hints on how this? i've been digging through docs domdocument on php.net i'm finding syntax pretty baffling! cheers, b edit: here sample of html file data tables i'd join http://thenetzone.co.uk/exrates/exrate.html ok got sorted phpquery , lots of tria...

in application i'm using following coding pattern vibrate iphone device include: audiotoolbox framework header file: #import "audiotoolbox/audioservices.h" code: audioservicesplaysystemsound(ksystemsoundid_vibrate); my problem when run application gets vibrate second want vibrate continuously until stop it. how possible? there numerous examples show how private coretelephony call: _ctserverconnectionsetvibratorstate , it's not sensible course of action since app will rejected abusing vibrate feature that. don't it.

all. i've been banging head few hours because of problem. have universal project that's mix of iphone , ipad projects. put these codebases universal project and, after lot of " #if __iphone_os_version_min_required >= 30200 " checks, got project run in both iphone (os 3.0 3.1.3) , ipad simulators. after doing more finagling project settings of external libraries load, got app load on iphone (which runs os 3.1.3). however, when run app on ipad, immediate sigabrt error. i've tried running under debug , under release , active architecture of both armv6 , armv7. i've checked , double-checked app has right nib files set (but, again, app runs fine in simulator). i've gone through external libraries i'm using , set them have same base sdk (3.2), same architectures (optimized (armv6 armv7)), same targeted device family (iphone/ipad), , same iphone os deployment target (iphone os 3.0). so, summarize... have universal app works in simulator iphone...

i trying figure out if possible create custom print port in .net. functionality trying achieve intercept data generated printer driver , send remote server instead of device. not really. either creating virtual port driver or network redirector requires native code. however... you capture data installing network print port , implementing server side in .net. example, lpr require create tcp socket server, , that's feasible in c#. i don't know of existing c# implementation, learn lot source code of p910nd .

i'm getting ready deploy cakephp site first time. i'm using site mysql database, , i'm still little unclear proper use of users & permissions mysql -- i'm talking "login" , "password" fields appear in app/config/database.php. during development, i've been using 'root' , 'root' -- i'm pretty sure can't idea. question is: best practices assigning mysql user cakephp app, , mysql privileges should assigned it? the least amount of permissions possible, insert, select, update, , delete on database in question, not create/drop privileges. best practice: make password hard guess. you're hardcoding anyways, there's no reason not make terrible monster of password. also, ensure can accessed localhost or ip. grant insert, select, delete, update on mydb.* 'myuser'@'localhost' identified 'monsterpassword'

i have straight, gradient line extends 1 end of screen other. what best (or only) approach screen wrapping line graphic, appears moving? my current " solution " draw horizontal line @ double width of screen , duplicate gradient pattern each half of line. line center-registered , it's moved toward right. once half of line traverses stage, line reset it's starting point. is there better way? well, alternative can think of using drawing api draw gradient stroke, calculating offset in each frame. more costly applying positional transform on display object. tiny bit of arithmetic alone should enough make slower. your proposed solution may not seem elegant , or efficient running in vm highly optimized drawing , transforming occluded vectors , bitmaps (and undependable on every other optimization) think best bet trust vm @ point. :)

i have upload code. there no problem running individually, when try add other codes, did not $_files parameter. im guessing becoz of enctype="multipart/form-data" in form tag, based on post: why file upload didn't work without enctype? the enctype needed. problem is, how can upload files without concern this? can juz change code structure compatible other codes? if($_post['check']){ $faillampiran=$_post['faillampiran']; $file=$_files['faillampiran']["name"]; $filesize = $_files['faillampiran']['size']; $filetype = $_files['faillampiran']['type']; if ($_files["faillampiran"]["error"] > 0 ) { echo "return code: " . $_files["faillampiran"]["error"] .

why invoke method thread.currentthread.interrupt() in catch block? this done keep state . when catch interruptexception , swallow it, prevent higher level methods/thread groups noticing interrupt. may cause problems. by calling thread.currentthread().interrupt() , set interrupt flag of thread, higher level interrupt handlers notice , can handle appropriately. java concurrency in practice discusses in more detail in chapter 7.1.3: responding interruption . rule is: only code implements thread's interruption policy may swallow interruption request. general-purpose task , library code should never swallow interruption requests.

how can see in java if object array without using reflection? , how can iterate through items without using reflection? i use google gwt not allowed use reflection :( i love implement following methods without using refelection: private boolean isarray(final object obj) { //??.. } private string tostring(final object arrayobject) { //??.. } btw: neither want use javascript such can use in non-gwt environments. you can use class.isarray() public static boolean isarray(object obj) { return obj!=null && obj.getclass().isarray(); } this works both object , primitive type arrays. for tostring take @ arrays.tostring . you'll have check array type , call appropriate tostring method.

i know can copy structure member member, instead of can memcpy on structures? is advisable so? in structure, have string member have copy structure having same member. how do that? copying plain assignment best, since it's shorter, easier read, , has higher level of abstraction. instead of saying (to human reader of code) "copy these bits here there", , requiring reader think size argument copy, you're doing plain assignment ("copy value here here"). there can no hesitation whether or not size correct. also, if structure heavily padded, assignment might make compiler emit more efficient, since doesn't have copy padding (and knows is), mempcy() doesn't copy exact number of bytes tell copy. if string actual array, i.e.: struct { char string[32]; size_t len; } a, b; strcpy(a.string, "hello"); a.len = strlen(a.string); then can still use plain assignment: b = a; to complete copy. variable-length data modelled...

i know if encrypt 2 or more strings in aes encryption. let's say, want encrypt username, password , nonce_value. can use following code? try { string codeword = username, password, nonceinstring; string encrypteddata = aseencryptdecrypt.encrypt(codeword); string decrypteddata = aseencryptdecrypt.decrypt(encrypteddata); system.out.println("encrypted : " + encrypteddata); system.out.println("decrypted : " + decrypteddata); } catch (throwable e) { e.printstacktrace(); } well work? why not try code , see? in theory can put multiple pieces of data 1 string , encrypt string, though you'd want better way of putting data together. current code, commas between username, password, , nonceinstring won't compile, if can prevent, instance, colon existing in of strings, like: string codeword = username+":"+password+":"+nonceinstring; and when decode split on colon.

i'm writing firefox extension analyze / parse linked pages while user still on current page. know there ways retrieve source code page being viewed, linked pages? if i'm able obtain url of linking page, able retrieve source code of url? my extension written in xul , javascript, code or sample add-ons me lot! maybe following javascript snippet you: var req = new xmlhttprequest(); req.open("get", linkedpageurl, false); req.send(null); dosomethingwithgivensource(req.responsetext); this works synchronously. after req.send(null) executed, req.responsetext contains page source code. recommended avoid synchronous network actions better approach use asynchronous request , add callback load event: var req = new xmlhttprequest(); req.open("get", linkedpageurl, true); req.addeventlistener("load", function() { dosomethingwithgivensource(req.responsetext); }, false); req.send(null);

i wondering if tell me how game , game engine fit game development. mean is, game engine not have game. i'm unclear basically, game developpers build engine, create new class inherits engine becomes game? ex: class shootergame : public engine { }; so i'm unclear on game code fits engine. the distinction between game , actual game engine architectural. game logic specific 1 game whereas game engine can reused. operating system provides utilities applications game engine same game code. game engines typically have different apis for: loading multimedia data audio, textures, 3d models providing game loop , firing off various events caused users input networking graphics rendering , various techniques make game nice using lighting, particle effects or bump mapping audio artificial intelligence an api allow defining game rules, game play, , game logic most game developers not write own game engine. work. instead they'll reuse game engine company ...

is there major performance difference between following: <iframe style="visibility:hidden" /> <iframe style="width:0px; height:0px; border:0px" /> i'm using hidden iframe pull down , parse information external server. if iframe attempts render page, may suck lot of cpu cycles. of course, i'd ideally want raw markup - example, if prevent iframe loading img tags, perfect. i think either way iframe going load it's contents. can simple test hiding , showing iframe page takes while load. if iframe (when made visible) shows long loading page, you'll know loaded in before show. if you're using firebug can use @ http requests made. show whether there's http request made iframe. as far performance differences, doubt there's between 2 pieces of html posted. if i'd setting visibility hidden more "efficient" since browser doesn't have wory rendering visually, if 0*0px. still, don't think the...

i have text in javascript this: this text<br>this second line of text and want have function return this text so find last <br> in text , give me before it. if text simple, .split() on <br> var str = "this text<br>this second line of text" var result = str.split('<br>')[0]; if more complex, may worthwhile use browser's built in html parser, can operate on them dom nodes. in case, this: var div, result, str = "this text<br>this second line of text"; (div = document.createelement('div')).innerhtml = str; var result = div.firstchild.data; ...or perhaps little simpler jquery: var str = "this text<br>this second line of text" var result = $('<div>',{html:str}).contents().first().text();
