i have page quite bit of work , don't want user able navigate away page (close browser, hit button, etc.) without getting warning. found onbeforeunload event (which think ie-specific, works fine me project uses lots of activex) works great. problem is, want user able click on little "help" icon in upper-right corner , pop window @ time. causes onbeforeunload fire, though main window never goes anywhere , page never unloads. the javascript function runs when onbeforeunload event runs puts text event.returnvalue. if ascertain, somehow, icon 1 clicked not put text event.returnvalue in situation. how have page figure out? let me guess: "icon" link javascript: url? change real button, real link, or @ least put functionality in onclick event handler (that prevents default behavior). problem solved. <!-- clicking link nothing. no onbeforeunload handler triggered. nothing. , put in before return false bit... ...and onunload handler still not cal...

i'm trying write small class library c++ course. i wondering if possible define set of classes in shared object , using them directly in main program demos library. there tricks involved? remember reading long ago (before started programming) c++ classes worked mfc .dlls , not plain ones, that's windows side. c++ classes work fine in .so shared libraries (they work in non-mfc dlls on windows, that's not question). it's easier windows, because don't have explicitly export symbols libraries. this document answer of questions: http://people.redhat.com/drepper/dsohowto.pdf the main things remember use -fpic option when compiling, , -shared option when linking. can find plenty of examples on net.

which os prefer program on? client or server there school of though if doing (mostly) web programming (or other server based code), should use server os dev machine, since that's closer environment app running. update: should add, directed windows crowd ok, know you're talking windows but... i used develop on windows deployment on *nix servers. sure there lots of gotchas way of working, kind of used it. in october 2005 switched linux, experiment, never went back. there steep learning curve. thought knew *nix pretty after 10 years of dealing it, knew nothing compared amount learned using on desktop machine. workflow has been smoother developing , deploying similar platforms. more recently, have started pick servers running ubuntu server, closely match our ubuntu desktop development machines. if talking difference between desktop , server edition, i'd guess needn't worry it. if you're developing on 1 os deployment on another, i'd consid...

i'm little bit stuck in problem right now: i've got jboss portal runs on jboss 4.2.3 . there running webapps on machine provide portlets users. need centralized solution: every time user logs in want create session bean user information hold. i'm using spring in webapps - information. how can achieve this? session bean must created asap when login occurs - can catch safely spring apps. several thoughts: is there possibility recognize login via listener? should use filter , check if request.getremoteuser() isn't null? maybe smth <bean id="userinfo" class="com.s.userinfo" scope="session"/> in application-context? 'session' can changed 'conversation', maybe.

i'm using c#. so have object has fields, doesn't matter what. have generic list of these objects. list<myobject> myobjects = new list<myobject>(); myobjects.add(myobject1); myobjects.add(myobject2); myobjects.add(myobject3); so want remove objects list based on criteria. instance, myobject.x >= 10. use removeall(predicate<t> match) method this. i know can define delegate can passed removeall, know how define inline anonymous delegate, instead of creating bunch of delegate functions used in once place. there's 2 options, explicit delegate or delegate disguised lamba construct: explicit delegate myobjects.removeall(delegate (myobject m) { return m.x >= 10; }); lambda myobjects.removeall(m => m.x >= 10); addition: performance wise both equal. matter of fact, both language constructs generate same il when compiled. because c# 3.0 extension on c# 2.0, compiles c# 2.0 constructs :)

i have wildcard subdomain enabled , dynamically parse url passing as-is index.php (ex. somecity.domain.com ). now, wish create few subdomains static can install different application , not co-mingle current 1 (ex. blog.domain.com ). my .htaccess reads: rewriteengine on rewritebase / rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewriterule . /index.php [l] can manipulate .htaccess achieve need? can done through apache? your .htaccess nothing useful, apache configured directoryindex index.php. well, move domain.com/a domain.com/index.php, doubt want. your wildcard virtualhost works because have serveralias *.domain.com in configuration, or single virtualhost , dns pointing address of server. (when have single virtualhost, shows request, , first listed virtualhost default one) you have create new virtualhosts static domains, leaving default 1 as, well, default 1 :) check these tutorials explain all.

i have problem. have web page adult content , several past months had ppc advertisement on it. , i've noticed big difference between ad company statistics of page, google analytics data , awstats data on server. for example, ad company tells me, have 10k pageviews per day, google analytics tells me, have 15k pageviews , on awstats it's around 13k pageviews. system should trust? should write own (and reinvent wheel again)? if so, how? :) the joke is, have web page, "normal" content (mmorpg fan site) , numbers +- equal in 3 systems (ad company, ga, awstats). think it's because it's not adult oriented page? and final question, totally offtopic, know ad company pays per impression , don't mind adult sites? thanks answers! first, should make sure not mix »hits«, »files«, »visits« , »unique visits«. have different meaning , called differently. recommend definitions if confused terms. awstats has correct statistics, because has access acces...

i'd use hashset in powershell script. think i've figured out how instantiate generic collection objects doing: [type] $strtype = "string" $listclass = [system.collections.generic.list``1] $listobject = $base.makegenerictype(@($t)) $mylist = new-object $setobject this works fine lists , dictionaries, when try create hashset get: unable find type [system.collections.generic.hashset`1]: make sure assembly containing type loaded. so looks need load system.core.dll can't seem powershell load assembly. example calling [system.reflection.assembly]::loadwithpartialname("system.core") causes exception: "loadwithpartialname" "1" argument(s): "could not load file or assembly 'system.core, version=3.5.0.0, culture=neutral, publickeytoken=b77a5c561934e089' or 1 of dependencies. system cannot find file specified." any pointers? powershell 2.0 makes easier 1) adding add-type cmdlet loading assembly , 2) up...

in past declared properties this: public class myclass { private int _age; public int age { get{ return _age; } set{ _age = value; } } } now can do: public class myclass { public int age {get; set;} } my question is, how can access private variable created automatically using notation? i rather access private variable , not public accessor 'age'. there default notation access private variable, or not possible? the aim of new automatic properties reduce amount of boilerplate code need write when have simple property doesn't need special logic in or set. if want access private member these properties use, that's few reasons: you need more simple get/set - in case, should avoid using automatic properties member. you want avoid performance hit of going through or set , use member directly - in case, i'd surprised if there performance hit. simple get/set members very easy inline, , in (admittedly li...

i have ui layout that's comprised of single outer layout contains 3 internal layouts. internal layouts header, body , footer. i cause top, header view become hidden if it's forced shrink past threshold. contains logo image, , if shrinks past point, i'd rather hide completely. what's best way this? there way accomplish statically in layout xml? if not, need subclass view , listen resizes? there way? subclass view override onlayout or onmeasure methods. when view decides width , height. after onmeasure completed, can call this.getmeasuredheight() , check if below threshold. if is, hide it.

in lua, can create table keys tables: t = {} t[{1,2}] = 2 i know how analogous thing using c api. is, writing c function callable lua, return table table keys. tried push table key , use lua_settable, seems nothing. edit: relevant code: lua_createtable(l, 0, n); for(i = 0; < n; ++i){ // push key table lua_createtable(l, 2, 0); for(j = 0; j < 2; ++j){ lua_pushinteger(l, j+1); lua_pushinteger(l, j); lua_settable(l, -3); } // push value table lua_createtable(l, 4, 0); for(j = 0; j < 4; ++j){ lua_pushinteger(l, j+1); lua_pushnumber(l, j); lua_settable(l, -3); } lua_settable(l, -3); } edit : being dumb; used lua_objlen(l, -1) @ end check on size of table, returns 0 since there no integer keyed entries. also, in lua code processed table, used ipairs instead of pairs . silly mistake. pushing table key , using lua_settable right thing do. likely, forgot push on value , did t =...

sorry wordy title - battling work out if problems caused by bad class design (likely) ignorance (very likely) both (most likely) i have spent ages googling due not understanding problem it's harder find solution. basically, have "day" class has observablecollection of period called periods. each period has length of time. have method/property of day class (totaltimeupuntilthisperiod) takes in period , returns amount of time of periods until point. i need put period level though datagrid can bind (it's itemssource set day.periods , it's datacontext set day). however, have calculation in day period instances don't know siblings , feels wrong if child walked tree parent level , summed children. my thinking - period should have no "state" ie. no idea of in day in relation it's siblings - job of day class. so, if class design correct - how can access datacontext in bound datacolumn? tried write converter take in period , parent da...

this along similar lines these recent questions: best java obfuscation application size reduction creating non-reverse-engineerable java programs however, 1 ends recommending yguard , other proguard neither mention both. wonder if comparison of each 1 , hear peoples experiences both sides of fence. looking @ comparison chart on proguard website angled towards proguard. real-world experience of each - 1 produces smaller output? 1 harder decompile from? java versions supported each? personally i'm particularly interested j2me point of view please don't limit discussion that. proguard better product; if take time go through settings j2me. specifically j2me there far better (commercial) product called mbooster i've been getting around 25% improvement in size on application after been through proguard. better zip compression on jar file , comprehensive support class merging , preverification.
