i'm playing around parsing xmpp xml stream. tricky thing xml stream start tag not closed until end of session, i.e. complete dom never received. <stream:stream> <features> <starttls /> </features> .... network session persists arbitrary time .... </stream:stream> i need read xml elements stream without caring root element has not been closed. ideally work doesn't , i'm assuming it's because reader waiting root element closed. xelement someelement = xnode.readfrom(xmlreader) xelement; the code below (which borrowed jacob reimers ) work i'm hoping there more efficient way doesn't involve creating new xmlreader , doing string parsing. xmlreader stanzareader = xmlreader.readsubtree(); stanzareader.movetocontent(); string outerstanza = stanzareader.readouterxml(); stanzareader.close(); xelement someelement = xelement.parse(outerstanza); you shouldn't need work strings; should

i want convert audio input being given through microphone text. prefer sapi , c# suggestions? or code samples? thanks !! you might want view previous threads, including getting started speech recognition , speech synthesis from thread: there article published few years ago @ http://msdn.microsoft.com/en-us/magazine/cc163663.aspx . best introductory article i’ve found far...

i have script developing creates sliding button type effect. 5 div's situated next eachother each link. when 1 of divs clicked on associated content expanded , rest of div's closed. the problem is, if user clicks div twice while loads or clicks div in rapid succession, cracks start show. i wondering if possible allow query executed once , wait until completion rather queuing it. here current code, if crap feel free comment on how better it... not best @ javascript/jquery :p function mnuclick(x){ //reset elements if($('#'+x).width()!=369){ $('.menu .menu_graphic').fadeout(300); $('.menu_left .menu_graphic').fadeout(300); $('.menu_right .menu_graphic').fadeout(300); $('.menu').animate({width: "76px"},500); $('.menu_left').animate({width: "76px"},500); $('.menu_right').animate({width: "76px"},500); } var elementid

is there model dependent variables censored on both sides? , if there implementation in r? aware of tobit models (e.g. in zelig package), they´re censored on left side... wonder if makes sense truncate on both sides... there's difference between truncation , censoring. need aware of case before start modeling. (in nutshell: censoring means events can detected, measurements not known (i.e. in case neither know exact beginning nor exact end of time interval subjects under risk event you're considering). truncation means events can observed if condition fullfilled: popular example survival in retirement home accepts people on 65 take residence - entry study population truncated @ age 65.) if have both left- , right censored data or data simultaneously right- , left-censored, techncal term looking interval censored. ?surv in package survival show how define interval censored observations modelling time-to-event in case.

note: not using both node.js , html5 sockets. i'm not interested in discussing merits of setup i'm describing. node.js runs on server, and, since supports connecting via sockets as client , can act middle layer between html5/js client , server uses tcp/ip (such database server.) so, both node.js , websockets include ways of opening socket connections server. my question is, has ported node.js script websockets, i.e., cut node.js out of equation, web browser connects database directly? imagine like: cut out http port usage of node.js-specific functions use websockets api if has been done, lot of trouble or node.js , websockets apis relatively similar? your question bit hard parse i'll take stab. if interested in connecting websockets client (browser) arbitrary tcp socket server, might interesting in wsproxy generic websockets tcp sockets proxy. wsproxy included novnc (html5 vnc client) , has 3 reference implementations in c, python , node (nod

how set last unused drive letter combobox in mfc (vc++) ? code : tchar g_szdrvmsg[] = _t("a:\n"); int main(int argc, char* argv[]) { ulong udrivemask = _getdrives(); if (udrivemask == 0) { printf( "_getdrives() failed failure code: %d\n", getlasterror()); //so getlasterror retuns sring or char*? } else { printf("the following logical drives being used:\n"); while (udrivemask) { if (!(udrivemask & 1)) m_objcmbdrive.addstring(g_szdrvmsg); ++g_szdrvmsg[0]; udrivemask >>= 1; } } } m_objcmbdrive.setcursel(); what value should pass setcursel set drive letter in descending order. this code gives me drive drive letters being used in system. how unused 1 out ? to select last item in combobox, can do: m_objcmbdrive.setcursel(m_objcmbdrive.getcount() - 1); to fill combobox unused drive letters in descending order, use insertstring() method: for

i have 1.0, 1.1, 1.2 branches , want every commit goesw 1.0 go automatically 1.1 , 1.2 , every commit 1.1 go automatically committed 1.2 is possible make in single transaction , automatically? can tell me how please? (can example please?) yes , no. can make atomic if checkout whole repository (or @ least branches folder). won't automatic though. have apply changes self other branches. different branches presumably have different code (you said version branches), applying same fix different branches may require different edits. can't (in general), avoid human intervention. i challenge idea of making 1 transaction. adversely impact quality of history. made independant changed in many places. if make merging other branches separate transaction history better reflect did (making 1 change , porting it). there reason need edit branches in 1 transaction?

we have asp.net 4 web application project. project contains number of pages. after having made changes error @ runtime (asp.net compile time) or namespace cannot found. at design time (in visual studio 2010) there no problem intellisense see these namespaces , classes, in project assembly themselves. , there no problems @ compile time in visual studio either. check out answer received similar question , see if trick (it did me!): .net extension method (this string foo) partially visible

it's not possible use wildcard in hosts file on windows or linux. there way browser plugin or else? i have dev server on vbox instance it's practically lan. i'm creating .dev domain virtual hosts example.com becomes example.dev. application i'm creating random subdomains (abd34dn.example.dev) should point dev server's ip. what options? instead of editing hosts file (which not work requirement), setup dns server , setup wildcard dns record -- *.example.dev in 1.2.3.4 you mentioned subdomains, assuming want host entries (a address entries) under example.dev. abcd.example.dev indicates "abcd" host entry, , not subdomain. if xyz.abcd.example.dev, "abcd" becomes subdomain. key point - since want abcd.example.dev - need dns records , suggested above.

i trying customize behavior of selenium's click command, (via user-extentions.js), intercepting calls doclick(locator). need delay click actions whenever our application's "busy indicator" being displayed. (now standard answer kind of thing insert waitfor script situations. indeed, have zillions of them throughout our scripts. i'm trying eliminate those.) detecting page element trivial part. tricky part getting script wait. promising looking, failed attempt looks this: var nativeclick = selenium.prototype.doclick; selenium.prototype.doclick = function(locator) { this.dowaitforcondition("!selenium.browserbot.findelementornull('busy-indicator')", 5000); return nativeclick.call(this, locator); } the dowaitforcondition gets called before every click, not wait when condition evaluates false. nativeclick gets called immediately, , no delay introduced. suspect dowaitforcondition function doesn't waiting per se, rather establishes co

i can't figure out way of selecting nth element, last element, or first element in cases don't know parent element. nth-child exists, children, example: <div> <p>one</p> <p>two</p> </div> p:last-child selects "two" paragraph, , p:first-child selects "one" paragraph. when have dynamic code , have no idea parent name is, or parent (may div, span, anchor, ul, etc.)? for example: <youdontknowwhat!> <p class="select-me">one</p> <p class="select-me">two</p> </youdontknowwhat!> how select second paragraph here? (i'm unable select youdontknowwhat! since don't know element (it's hypothetical name). why there first-child , last-child , , nth-child selectors , no :first , :last , :nth (like .select-me:first )? how :first different :first-child ? every html element child of other element in dom except <html> root e

we've got python-based web server unpickles number of large data files on startup using cpickle . data files (pickled using highest_protocol ) around 0.4 gb on disk , load memory 1.2 gb of python objects -- takes 20 seconds . we're using python 2.6 on 64-bit windows machines. the bottleneck not disk (it takes less 0.5s read data), memory allocation , object creation (there millions of objects being created). want reduce 20s decrease startup time. is there way deserialize more 1gb of objects python faster cpickle (like 5-10x)? because execution time bound memory allocation , object creation, presume using unpickling technique such json wouldn't here. i know interpreted languages have way save entire memory image disk file, can load memory in 1 go, without allocation/creation each object. there way this, or achieve similar, in python? try marshal module - it's internal (used byte-compiler) , intentionally not advertised much, faster. note doesn't

i'm building login part of codeigniter app using simple login class starting point. it's working fine, i'm unsure of differences between encryption types, , use. i've gone using crypt() function user's password salt (via md5), so: $pass == crypt($_post['login_password'], md5($_post['login_password'])) is method ok, or there glaring error in approach? seems secure neither password or salt stored in database. or bit obvious? thanks in advance. http://php.net/manual/en/faq.passwords.php this correct way implement passwords. everything below irrelevant. with have right there, simple $pass = md5($_post['login_password'] . "somerandomchars"); will suffice in cases unless high degree of security required. if you're using codeigniter highly suggest looking tankauth authentication plugin.

we use subversion source control , have implemented pre-commit hook checks comments , not allow commits without comments. i use toad mysql 5 manage db. provides way integrate svn , put db in source control not provide way add comments part of commit. is there way either a) provide default comment svn pre-commit hook checks comments gets or b) way override pre-commit hook checks comments toad client. you can tell doing commit (the author) using svnlook, try setting specific user toad client - that's not acceptable. the alternative allow blank commits specific file types (or repo paths) in pre-commit hook script itself. you cannot interfere suppled transaction in pre-commit hook, inspect , accept or reject it. there no client "host-agent" supplied in transaction.

before starting sorry awfull coding skills , hope can me advices , such. i have hashset of unique int values: private hashset<int> found = null; that use read data entity, each entry inserted on found unique , gives me whole new set of data. so let's consider each unique int follow data: id,m,x,y,z the hashset updated every second , when happens may gather repeated entities new data still have compare if not updating duplicated entity. so made dictionary follow dictionary<int, mylist> myitemlist = new dictionary<int, mylist>(); and above class mylist public class mylist { public int id { get; set; } public string m { get; set; } public string x { get; set; } public string y { get; set; } public string z { get; set; } } so here sample of found feeding dictionary: foreach (var myfoundid in found.except(myitemlist.keys)) { mylist listdata = new mylist(); listdata.id = get(myfoundid, "id"); listdata.
