how can display in datagridview selected properties of object, , selected properties of member object of first object? think not require binding rely on hard coding updates, because updates initiate on non-ui threads, , think not easy bind. @ least i've had problems in other project. basically i'm looking understand different ways can this. maybe linq, or whatever suitable. note: want display data in same table. child/parent 1:1 relation. so example code: public class user public property score integer public property details userdetails end class public class userdetails public property name string public property username string end class hence, want table show columns: score, name, username edit: oh, more easy thought, seems work: dim q = (from n in userlist select new {n.score, n.details.name, n.details.username}).toarray you can use databinding here, if use itypedlist interface expose properties wanted. itypedlist powerful, hard understand

i have written following basic tuple template: template <typename... t> class tuple; template <uintptr_t n, typename... t> struct tupleindexer; template <typename head, typename... tail> class tuple<head, tail...> : public tuple<tail...> { private: head element; public: template <uintptr_t n> typename tupleindexer<n, head, tail...>::type& get() { return tupleindexer<n, head, tail...>::get(*this); } uintptr_t getcount() const { return sizeof...(tail) + 1; } private: friend struct tupleindexer<0, head, tail...>; }; template <> class tuple<> { public: uintptr_t getcount() const { return 0; } }; template <typename head, typename... tail> struct tupleindexer<0, head, tail...> { typedef head& type; static type get(tuple<head, tail...>& tuple) { return tuple.element; } }; template &l

i've implemented wurfl based detection routine based on similar strategy 2 phase 1 outlined @ http://wurfl.sourceforge.net/newapi/ . this working improve worst case scenario if can. in worst case scenario, @ moment, every device's user agent string compared against current user agent string. what i'm curious how valid search tree of devices , cull entire branches device matches don't minimum match threshold? (obviously ignoring 'root' devices don't have user agent strings intended matching) do user agent strings tend follow general pattern of ever closer matches 1 decends down tree... , make aforemention strategy valid? ... or user agent strings random beast in terms of parent verse child device matches , forced search entire tree every single time? wurfl-pro, company beside wurfl project, has dual licensing strategy. can ask them obtain gpl-free library. for know wurfl java api implementation can browse source available on svn...or

the typical pattern i've seen using pthread_cond_wait is: pthread_mutex_lock(&lock); while (!test) pthread_cond_wait(&condition, &lock); pthread_mutex_unlock(&lock); why can't if statement used instead of while loop. pthread_mutex_lock(&lock); if (!test) pthread_cond_wait(&condition, &lock); pthread_mutex_unlock(&lock); http://pubs.opengroup.org/onlinepubs/9699919799/functions/pthread_cond_timedwait.html when using condition variables there boolean predicate involving shared variables associated each condition wait true if thread should proceed. spurious wakeups pthread_cond_timedwait() or pthread_cond_wait() functions may occur. since return pthread_cond_timedwait() or pthread_cond_wait() not imply value of predicate, predicate should re-evaluated upon such return. the while loop standard way of re-evaluating predicate, required posix.

i'm using twitter4j , android facebook sdk fetch status messages. twitter4j real-time notifications whenever new status has been added stream via statuslistener (twitter4j). in facebook sdk cannot find similar way, can fetch entire streams on , on again in fixed time interval using requestlistener (facebook sdk) far see it. is there way notified of new statuses in realtime facebook sdk in similar way twitter4j? (found similar unanswered question here: facebook real-time updated application wall ) there realtime api http://developers.facebook.com/docs/api/realtime but it's server-to-server communication, it's not useful if have mobile app without server infrastructure app can subscribed - looking in particular case. see q&a @ http://forum.developers.facebook.net/viewtopic.php?id=56610

i have following javascript code run notepade.exe: <script type="text/javascript" language="javascript"> function executecommands() { var oshell = new activexobject("shell.application"); var commandtorun ="c:\windows\notepad.exe"; oshell.shellexecute(commandtorun,"","", "open", "1"); } </script> the problem that, when run script give error..."permission denied." can me on matter? it's necessary have 2 settings turned on. enable unsigned activex controls current zone tools > internet options > security > custom level... enable "activex controls , plug-ins" > "initialize , script activex controls not marked safe scripting" allow active content run files tools > internet options > advanced > security enable "allow active content run in files on computer&quo

i want regular expression accepts numeric between 15 17 digits. ^\d{15,17}$ - digit (use [0-9] instead of \d avoid unicode characters, if applicable). ^[1-9]\d{14,16}$ - if don't want number start zeros. of course, might easier parse number , check it, fits nicely in long value.

does know sidebar (or 'panel' it's called in opera) can use number conversions (decimal hex , on)? i'm using this one it's bit large fit narrow sidebar. since it's bit of javascript, 1 can roll oneself: <html> <body> <form> <input name="dec" id="dec" placeholder="decimal" onblur="document.getelementbyid('hex').value= parseint(this.value,10).tostring(16)" ></input> <br /> <input name="hex" id="hex" placeholder="hex" onblur="document.getelementbyid('dec').value= parseint(this.value,16).tostring(10)" ></input> </form> </body> </html>

as know. list add method works below. list<string> cities = new list<string>(); cities.add("new york"); cities.add("mumbai"); cities.add("berlin"); cities.add("istanbul"); if designed data structure this list<object> lstobj = new list<object>(); if (true) // string members { cities.add("new york"); cities.add("istanbul"); } else // list obj members here { list<object> alistobject= new list<object>(); cities.add(alistobject); // how handle this? } does list add method works or not if add different types members in same function. you can't add list<object> list<string> . thing can add list of strings strings (or null references). use instead: list<object> cities = new list<object>(); but seems bad design. when use object generic type of collection lose benefits of type-safety. for parsing xml i'd sugge

i have requirement need have custom ribbon added word 2007 file populated items. created add-in using this , pressing f5 opens word file contains newly added custom ribbon. save word file , open again , not have newly added custom ribbon. sure missing here.could throw light? i save word file , open again are opening again outside of word instance running visual studio? add-in might available when you're debugging project. check if entry add-in exists in registry, under: hklm\software\microsoft\office\word\addins\ . if no entry exists, i've found easiest way deploy vsto add-in machine create setup project in visual studio.

i've been trying out nhibernate 3 , linq nhibernate. can't spit out correct t-sql query. here's domain model: employee { id, name } department { id, name } employeedepartment { id, employee_id, department_id, startdate, enddate } attendanceregistration { id, datetime, employee_id } now suppose i'd select attendanceregistrations between '2010-10-1' , '2010-11-1' connected department @ time. datetime start = new datetime(2010,10,1); datetime end = new datetime(2010,11,1); var list = ar in session.query < attendanceregistration > () start <= ar.datetime && ar.datetime > end && ( ed in session.query < employeedepartment > () ed.startdate <= ar.datetime && ed.enddate > ar.datetime && ed.department_id = 1 select ed.employee_id ).contains(ar.employee_id) select ar; the resulting sql code this: sel
