i having trouble active directory authentication using formsauthentication in asp.net mvc 2 (vs 2010). as understand should able step into/through microsoft source code formsauthentication.authenticate if check 'enable source server support' , 'enable .net framework source stepping' in options->debug->general , specify 'microsoft symbol servers' in options->debug->symbols. i have done , can step whole bunch of ms source code, not formsauthentication.authenticate . debugger simple steps on it. can tell me why is? if step formsauthentication.authenticate make life whole lot easier. thanks. ok, stupid. i should have been using membership.validateuser not formsauthentication.authenticate. my problems solved :) however, never figured out why not step formsauthentication.authenticate. guess remain mystery...

i try explain better. have 1 user control in page, , inside have uc2 (modal pop up). , try achieve this: when close uc2(modal) try update fields on uc1. , works fine one(i have uc2(modal) , on button save onclientclick="saveinfoci()"), , in uc1 on top of page function saveinfoci() { document.getelementbyid("<%=frmdata.findcontrol("txtimplementingci").clientid%>").value = document.getelementbyid("<%=uc2.getclientid%>").value; } but because reuse control in place want update field. have 3 js function update 3 fields. , try when click save in uc2(modal) must execute 1 of 3 javascript f, update right field. don't want have 3 same uc difference in onclientclick="saveinfoci(). two problems: first, syntax off, when inside code behind can't use <%= this. second problem, time script executed (on top of page) elements still not exist. have change value in client side page load event. so should work,

i've been looking @ akka , it's pretty impressive. looks has of killer features of erlang - location transparency, supervision hierarchies, , more. there features erlang has akka doesn't? disclaimer: po akka erlang copy-on-send - akka uses shared memory (immutable objects) in-vm sends erlang per-process gc - akka uses jvm gcs erlang has otp - akka integrates entire java ecosystem (apache camel, jax-rs, etc etc) erlang process scheduling - akka allows use many different dispatchers endless configuration opportunities erlang hot code reload - akka can support it, it's less flexible because of jvm classloading those ones top of head. on other hand, using akka means can use scala, java, groovy or jruby write applications.

i person in company tries solve coldfusion errors , bugs. daily emails full details of coldfusion errors etc, store information in our database. and few different applications in coldfusion, seem sporadically generated "violation of primary key constraint" errors. in code check existence of row in database before try insert, , still generate's error. so thinking is, either need cftransaction around these each of check, insert or update blocks. not sure solve problem. these coded in standard coldfusion style/framework. here example in pseudo-code. cfquery name="check_sometable" datasource="#dsn#" select id sometable /cfquery if check_sometable.recordcount gt 0 -do insert else -do update /endif so why intermittently, cause primary key violations? is sql server problem, missing configuration option? are getting of because not on latest hotfixed version of coldfusion 8 standard? do need upgrade our jdbc/odbc drivers? thank you.

i'm trying check expired property of user's current formsauthenticationticket see if authentication period has expired. when period has expired, i'm never able enough information create ticket check. i've tried this: formsidentity id = (formsidentity)user.identity; formsauthenticationticket ticket = id.ticket; but user null when authentication period has expired. won't work. i've tried this: httpcookie authcookie = context.request.cookies[formsauthentication.formscookiename]; formsauthenticationticket authticket = formsauthentication.decrypt(authcookie.value); but forms cookie gone when authentication period has expired, meaning authcookie null. doesn't work. is there way get formsauthenticationticket object when authentication period has expired? there must be, because there's "expired" property in object. missing? thanks. an expired cookie left out of headers client browser. there no code-behind method of retrieving

i have simple question i.e. how can pass objective-c function reference c function pointer c can invoke function. edit: sorry not providing sample source here is: - (void)init { clibstructure clibobject; clibobject.on_work_done = &cworkdone; } the function point on_work_done have signature in c static void cworkdone(const char *workinfo); whereas in objective-c signature made - (void) workdonewithstatusmessage:(const char *message); now want point clib.on_work_done pointer objective-c function, if point standard c function works. in short, can't. not directly. a method call combination of target, object message, , selector identifies method call. you need bundle somehow. blocks easy enough. pure c apis, can typically done context pointer or it. given posted no code, no examples, none of api used, , none of details c api itself, providing details difficult.

i'm wondering if can destroy/modify sessions in native php way doesn't involve file i/o directives. i'm not talking $_session, i mean access session files themselves . for instance, php stores sessions on linux files: @lamp:/var/lib/php5$ ls sess_301dc8935f1775312e9007431782c68b sess_6892f0bec257e646d193adfd91233c40 sess_966909941003dd6fd333727d8862be6e sess_cb7c07117cef89674a686ffff8a730f2 sess_ffb4db1d9002741b7e0fcc02090b9aaa sess_305aeb0fdba7548e389394cb31d77c3b .... etc $_session gives value of what's inside current session, , session_start() , session_destroy() terminate current session identifier. i want know if can destroy or modify sessions globally in native way php doesn't resort me having fopen(/var/lib/php5/sess_whatever) , don't want work current session, want script able either delete or modify sessions outside of $_session , session_start , , session_stop do, force use present session. sounds me can't have both ways.

wasn't sure how phrase title, question is: i've heard of programmers allocating large section of contiguous memory @ start of program , dealing out necessary. in contrast going os every time memory needed. i've heard faster because avoid cost of asking os contiguous blocks of memory constantly. i believe jvm this, maintaining own section of memory , allocating objects that. my question is, how 1 implement this? thanks, dragonwrenn most c , c++ compilers provide heap memory-manager part of standard library, don't need @ in order avoid hitting os every request. if want improve performance, there number of improved allocators around can link , go. e.g. hoard , wheaties mentioned in now-deleted answer (which quite -- wheaties, why'd delete it?). if want write own heap manager learning exercise, here basic things needs do: request big block of memory os keep linked list of free blocks when allocation request comes in: search list block

using jpa2/hibernate, i've created entity has uni-directional mapping entity x (see below). inside a, have transient member "t" trying calculate using @postload method. calculation requires access assosiated xs: @entity public class { // ... @transient int t; @onetomany(orphanremoval = false, fetch = fetchtype.eager) private list listofx; @postload public void calculatet() { t = 0; (x x : listofx) t = t + x.somemethod(); } } however, when try load entity, "org.hibernate.lazyinitializationexception: illegal access loading collection" error. @ org.hibernate.collection.abstractpersistentcollection.initialize(abstractpersistentcollection.java:363) @ org.hibernate.collection.abstractpersistentcollection.read(abstractpersistentcollection.java:108) @ org.hibernate.collection.persistentbag.get(persistentbag.java:445) @ java.util.collections$unmodifiablelist.get(collections.java:1154) @

i going through zed shaw's learn python hard way , in chapter 15 struck me. in credit exercises asks delete latter part of code [everything after print txt.read() ] , execute it, interpreter behaves if nothing has happened. yes, saved file , when modified adding print statements changes still showed up, same voodoo code executed. why? what's going on over here? from sys import argv script, filename = argv txt = open(filename) print "here's file %r:" % filename print txt.read() print "i'll ask type again:" file_again = raw_input("> ") txt_again = open(file_again) print txt_again.read() you executing different file 1 editing.

hopefully simple question. have simple custom forum on site written in php. security reasons don't allow html in forum posts. allow bbcode tags. allow embedded youtube videos. so question this: what's best (most secure) way validate youtube embed code? youtube using iframes embed videos, can't allow iframe tag. need ensure src of iframe youtube url, , ensure there's no other malicious bits of code in iframe code. you should allow users use this: [youtube]http://www.youtube.com/watch?v=te-til9yvae[/youtube] and turn embed code using php when displaying message: function bb_youtube($post) { return preg_replace( "#\[youtube].*?v=([^&]+).*?\[/youtube\]#im", '<object width="480" height="385"><param name="movie" value="http://www.youtube.com/v/$1?fs=1"></param><param name="allowfullscreen" value="true&qu

i have encrypted odt (open document text) file , need unzip it. odt zip file. encrypted odt normal zip file, files inside zip encrypted. using zipfile works okay in test, cannot use zipfile because have stream in memory, don't want work file. therefore use zipinputstream . using zipinputstream.getnextentry() throws dreadful only deflated entries can have ext descriptor exception. from can understand, throws on first encrypted file inside zip package, example on content.xml. because openoffice has encrypted xml file, no point compressing , stored inside zip package uncompressed. but zipinputstream seems have problem , don't see way around. and yes, encrypted odt file created openoffice writer 3.2.1. , yes, stock zipinputstream cannot enumerate through entries in it. anything can suggest? you can have if it's possible odf toolkit library

i developing desktop application want show message in alert panel using nsrunalertpanel. doing following things: nsstring *title = @"% test"; nsstring *message = @"% test message"; nsrunalertpanel(title, message, @"ok" ,@"cancel" ,nil); the alert panel show title properly. i.e % test but, message est message; want display % test message. how solve problem? thanks in advance. try : nsstring *title = @"% test"; nsstring *message = @"%% test message"; nsrunalertpanel(title, message, @"ok" ,@"cancel" ,nil); why? nsrunalertpanel uses nsbeginalertsheet . looking @ documentation nsbeginalertsheet can see there more parameters after msg (specified ... ). this tells title string literally displayed message can have format parameters same way [nsstring stringwithformat:] does. the way string specifies there going parameter using % character i.e. %i means ' put integer here '

i new c++. while trying sample polymorphism code, found base class virtual function definition in derived class possible when defined within derived class or outside declaration in derived class. following code gives error: class b { public: virtual void f(); }; void b::f() { std::cout<<"b::f"; } class d : public b { public: void f2() {int b;} }; // error: no "void d::f()" member function declared in class "d" void d::f() { std::cout<<"d::f"; } it works if declare f() inside d. wondering why need explicitly declare function again when declared in base class. compiler can signature base class right? thanks in advance.. you can't add members class outside of class definition. if want d have override b::f have declare inside class definition. rules. declaring member in base class doesn't automatically give derived classes identical member. inheriting base gives derived class members of

i have asp mvc 2 project, written in vs 2008 upgraded vs 2010. want, however, remain .net 3.5 since production environment not have .net 4 installed yet. thought possible. when upgraded project answered no question upgrading .net framework version. have checked , .net 3.5 set target framework in advanced compile options project. my problem can write code builds , runs fine in vs doesn't work in .net 3.5 environment. example, added function optional paramater of type integer? (nullable integer). appears allowed in 4 not in 3.5? anyway, works fine in vs 2010. however, when try build , deploy run 1 of 2 problems. (we use custom build/deploy scripts - build uses msbuild on separate build server.) porblem 1 if try use 3.5 version of msbuild. build fails message "error bc31405: optional parameters cannot have structure types." . problem 2 if try use .net 4 version of msbuild on build server (remember target framework still 3.5, change msbuild executable buil

it nice speed testing able run tests on multiple machines (this acceptance/integration tests, not unit tests...). there existing easy way using nunit? @dotnetwise points out nunitgridrunner dead, , author proposes alternatives: note: i've given on project i've found jetbrain's team city provides viable option. cruise provides grid processing not good. the team city "build grid" feature might you're looking for. think don't want pnunit . while stands "parallel nunit," home page says: pnunit not intended "casual" parallelism merely make tests run faster. rather, it's intended way test applications composed of distributed, communicating components.

is possible create custom admin action django admin doesn't require selecting objects run on? if try run action without selecting objects, message: items must selected in order perform actions on them. no items have been changed. is there way override behaviour , let action run anyway? yuji on right track, i've used simpler solution may work you. if override response_action done below can replace empty queryset queryset containing objects before check happens. code checks action you're running make sure it's approved run on objects before changing queryset, can restrict happen in cases. def response_action(self, request, queryset): # override allow exporting of records csv if no chkbox selected selected = request.post.getlist(admin.action_checkbox_name) if request.meta['query_string']: qd = dictify_querystring(request.meta['query_string']) else: qd = none data = request.post.copy() if le

i have stored procedure in db returns different columns different conditions. (dynamic sql). when use sqlhelper class , execute stored proc in business layer, returns possible columns (from if/else conditions in dynamic sql) in dataset returned. other columns should not part of result set blank. columns come db constraints on them. every time use dataset have set "enforceconstraints" false. there better approach, 1) avoid bringing constraints db? or 2) required dynamic columns db? thank you are datatables being generates weakly or using typed datasets? probably not want hear, advice have different sps different result sets. of inference of result sets e.g. datasets works off sp if sp can return different things based on supplied data, you'll start see issues you've seen.

what mobile phones supporting java android? is there nokia phone supporting technology? what should mobile contain (a framework, plugin.. etc) if want deploy java android application? there comprehensive list on wikipedia comparing devices running android, including forthcoming devices. nokia seems have no interest using android platform devices. if device certified android platform, there nothing 1 needs add deployment.

i have this: <installexecutesequence> <removeexistingproducts after="installvalidate"/> </installexecutesequence> since 1 of uninstallation fails need execute custom action solve problem before removeexistingproducts. in lines of: <customaction id="fixstuff" .. /> <installexecutesequence> <custom action="fixstuff" before="removeexistingproducts" /> <removeexistingproducts after="installvalidate"/> </installexecutesequence> this of course doesn't work since custom action cannot before installinitialize. i'd remove existing products between installvalidate , installinitialize, i'd execute fixstuff before removing existing products. is possible that? unfortunately cannot run elevated custom action before removeexistingproducts current configuration. some possible approaches be: move removeexistingproducts right before installfinalize. solves cus

is declaring variable inside of loop poor practice? seem me doing so, seen in first code block below, use ten times memory second... due creating new string in each iteration of loop. correct? for (int = 0; < 10; i++) { string str = "some string"; } vs. string str; (int = 0; < 10; i++) { str = "some string"; } is declaring variable inside of loop poor practice? not @ all! localizes variable point-of-use. it seem me doing so, seen in first code block below, use ten times memory second the compiler may optimize things keep memory use efficient. fyi: can it, if use final keyword tell variable has fixed reference object. note: if have more complex object executing complex code in constructor, may need worry single vs. multiple executions, , declare object outside of loop.

i have following part of code : for(int i=0;i<n;i++) { printf("student %d\n",i+1); printf("enter name : "); scanf("%s",&(student+i)->name); fflush(stdin); lengthname = strlen((student+i)->name); while(lengthname !='\0') { }} when length shorter 10, add hyphens until reaching maximum size. ex : john =>> 6 hyphens added i know how in csharp can't figure out in c. of give me lights please? ps : oh yes variable name char name[10+1] , part of structure called student. this simple seems must missing something. lengthname = strlen(student[i].name); while (lengthname < 10) student[i].name[lengthname++] = '-'; student[i].name[lengthname] = '\0'; perhaps confused c#'s (presumed) possession of first-class string type? no such thing in c, bare arrays of characters; @ once tedious (you have memory management yourself) , liberating (as see above).

i need loop through components , assign event handler (for example dynamically assigning onclick event tbutton to showmessage('you clicked on ' + (sender tbutton).name); the problem in cases assigned tbutton onclick event. is there way solve problem? let's imagine have button1 harcoded onclick event handler is: showmessage('this button1'); after "parsing" full event handler button1 becomes: showmessage('this button1'); // design time event handler code showmessage('you clicked on ' + (sender tbutton).name); // runtime added note: looking soliution allows me use tbutton without inheriting it. you assignment of onclick before overwriting it, persist , use in new handler - chaining events. something this: var original : tnotifyevent; original := component.onclick; component.onclick := newmethod; and in newmethod: if assigned(original) original(sender); you'll not want single original variable

this question has answer here: mysql execution time 3 answers i execute mysql queries php , know how time consuming are. there way execution time of mysql query php? i wonder if execution time depends on how loaded web server. can imagine query take more time execute if server busy other queries. on other hand, can imagine that, if server busy, query wait turn , executed (without queries executed in parallel) , waiting time not included execution time. so, scenarios (out of two) correct? there way via mysql, however, easy (and reliable) way using php's microtime function, returns current time milliseconds. microtime() returns current unix timestamp microseconds. function > available on operating systems support gettimeofday() system call. getasfloat - when called without optional argument, function returns string "msec sec" s
