how can display in console list of <input> tags inside html? i've tried use $('input') , $(':input') , or $('tbody input') of commands returns jquery.fn.jquery.init[<number>] . anyways, using google chrome. yet think wouldn't affect other browsers, of course ie exemption. $('input') correct approach. $(...) returns jquery object , jquery.fn.jquery.init[<number>] console's representation of such object. it means have array object , constructed function jquery.fn.jquery.init , <number> elements. that's normal , code works fine (at least in regard), $('input') correct approach. of course should make select elements after document loaded, explained jquery tutorial .

say have list of valid scheduling days. like: 23, 27, 29 i want modify given date it's next valid day-month based on above list. if given date "23/11/2013" next valid date "27/11/2013" if given date "30/11/2013" has return "23/12/2013" , if given date "30/12/2013" has return "23/01/2014" i've done in sql, i'm translating c# , it's bit tricky. i'm trying using linq on list sql similarity, gets confusing. the sql statement (yes, know doesn't swift year): select top 1 @date = isnull(dateadd(yy, year(@date)-1900, dateadd(m, (month(@date)+case when datepart(day,@date)>[day] 1 else 0 end) - 1, [day] - 1)),@date) @days dateadd(yy, year(@date)-1900, dateadd(m, (month(@date)+case when datepart(day,@date)>[day] 1 else 0 end) - 1, [day] - 1))>=@date order [day] @days working table. i think you're looking (using linq): public static datetime nextdate(datetime seed, int[

hi change name of running hadoop job meaningful name. there command change name of running job, - hadoop job -set-priority <job_id> 'high'; changes priority of job the job id assigned job tracker on submit, calling jobtracker.getnewjobid() . cannot pre-set. change the job priority, must retrieve id submission. read comments on pig-948 why not possible know mr job id pig: reason jobcontrolcompiler compiles set of inter-dependent mr jobs , generates job-control object submitted asynchronously hadoop execution. since dont block on thread, possible job-ids not yet assigned when ask them

when should use default parameters ? proper syntax , should not used? using them regularly or bad habit? affect efficiency? only case can think of affects efficiency when include big default parameter it's not used of callers. example: #include <iostream> void foo(std::ostream& out=std::cout) { out << "foo"; } if none of callers use default parameter, , rest of program doesn't need <iostream> have been included in vain, increasing executable size (and compilation time may or may not matter much).

i having weird problem in code, when execute code first if condition, works fine , excpected. however, when comment if statement , use other if condition (the 1 commented ), gives npe. both getuserip() , getphonenumber() normal getters private strings. , both values being set before normal setters. idea why happening ? thanks. public void sendbroadcast(final string broadcast) { system.out.println("entered sendbroadcast"); string fullpeep=broadcast; system.out.println("fullpeep: "+fullpeep); string array[] = fullpeep.split("<!!>"); for(user tempuser: friends) { if(tempuser.getuserip().equals(this.getuserip())) { system.out.println("tempuser:" +tempuser.getphonenumber() + " user: "+array[1] ); //if(tempuser.getphonenumber().equals(array[1])) //{ system.out.println("tempuser:" +tempuser.getphon

i have created div dynamically. tried add class expanded through jquery not working. tried code in console, working fine there. code follows: appending element name var menuid= '#itemmenu' + indexofelement; and tried this $(menuid).addclass('expanded'); when tried folllowing in console e.g. $('#itemmenu5').addclass('expanded') its working fine.. var menuid= 'itemmenu' + indexofelement; var element = document.getelementbyid(menuid); element.classname += ' expanded'; //note space

i have excel sheet user can enter data several cells. want data treated strings, regardless if user enters "hello" or "123" or "12.12.2012". i partially resolve issue formatting input cells "text". if user enters number such "123" or string looks date ("12.12.2012"), appears small green rectangle , excel says number stored text, that's want. same thing text "1.2.90" in cell a5 seen excel "date stored text". text "aa" in cell a4 ok. when click on exclamation mark icon, can choose ignore "error", removes green triangle, change content of cell putting number, green triangle appears again. green field formatted "text" is there way force excel leave data entered string ? non vba version you can switch off error tracking file tab. read it, check ms link . vba version to using vba, need switch off backgroundchecking using application.errorcheckingopti

i have 3 groups of items(names). group 1 has around 2,1k items, group 2 - around 7,6k , group 3 around 21k. need search in these groups. need hint better. thought either put in bin tree: gtree* t = g_tree_new((gcomparefunc)g_ascii_strcasecmp); , search this: goup = g_tree_lookup(t, (gpointer *)itemname); or more efficient make 3 arrays of strings: char g1[2300][14]; char g2[8000][14]; char g3[78000][14]; and search (not checked, pseudocode): int isvalueinarray(char val, char *g[][14];, int size){ int i; (i=0; < size; i++) { if (memcmp(val, g[i], strlenth) == 0) return true; } return false; } int group=0; if (isvalueinarray(itemname, g2, 7800) ) group = 2; if (isvalueinarray(itemname, g1, 2300) ) group = 1; or there better solution that? if want asymptotically efficient way of finding whether string in set of strings can pre-processed, can consider using a trie . construction

i have route want able navigate in series. unfortunately backbone doesn't make possible navigate same route twice. is possible not save route history? i have route: app_router.on('route:deletefile', function(filename){ var r=confirm("do want delete "+filename); if (r==true) { //delete instruction } }); if don't accept confirm mistake, can't choose same file delete again. because route reached. one solution consist of navigating previous route when don't accept confirm, without triggering : app_router.on('route:deletefile', function(filename){ var r=confirm("do want delete "+filename); if (r==true) { //delete instruction } else { backbone.history.navigate(/* previous rout */, {trigger: false}); } });

first question : confused between buffers in tcp. trying explain proble, read documentation tcp buffer , author said lot tcp buffer, thats fine , explanation beginner. need know tcp buffer same buffer 1 use in our basic client server program ( char *buffer[some_size] ) or different buffer hold tcp internally ? my second question sending string data prefix length ( this data me ) client on socket server, when print data @ console along string prints garbage value "this data me zzzzzz 1/2 1/2....." ?. fixed right shifting char *recvbuf = new char[nlength>>3]; nlength 3 bits why need in way ? my third question in relevance first question if there nothing tcp buffer , char *buffer[some_size] whats difference program notice using such static memory allocation buffer , using dynamic memory allocation buffer using char *recvbuf = new char[nlength]; . in short best , why ? client code int bytessent; int bytesrecv = socket_error; char sendbuf[200] = "this
