i'm wondering difference between 'span' , new html5 tags 'figure' , 'area'. what intended purpose of each, , appropriate uses? example, use 'span' background image rather 'img' tag prevent image being selectable; best element accomplish this? <span> inline element, used inline div. "generic wrapper phrasing content not represent anything." ( w3c spec ) <figure> used alongside <figcaption> element mark "can moved away main flow of document without affecting document’s meaning." ( w3c spec ) <area> making image maps, , used inside <map> element. in case, i'd recommend using div instead, or img tag transparent png content background image. use img tag user-select:none; usual prefixes instead stop image being selectable.

i want change text of 2 labels based on selected row of gridview. i keep getting error says public member row not exist on linkbutton protected sub linkbutton1_click(byval sender object, byval e system.eventargs) dim linkbutton1 linkbutton = directcast(sender, linkbutton) dim tour label = ctype(sender.row.findcontrol("label2"), label) dim depart label = ctype(sender.row.findcontrol("label3"), label) test.text = tour.text test1.text = depart.text updatepanel9.update() end sub according code, sender linkbutton . property row won't exist on link button when reference sender.row . that's why error. you want hook selectedindexchanged event, give access row more easily. sub mygridview_selectedindexchanged(byval sender object, byval e eventargs) dim mygrid gridview = trycast(sender, gridview) dim selectedrow gridviewrow = mygrid.selectedrow 'do selected row needed here..... end sub

i have 2 domain-classes. class usersaddthese { string somedata } and class theseareconstantlygenerated { usersaddthese theproblem } is there way delete usersaddthese , automatically delete theseareconstantlygenerated or should add in logic findallbytheproblem , iterate , delete. (i prefer if done automatically can add new generated classes refer usersaddthese , not change delete controller.) alternatively, there way tell gorm, "if else depends on deleting cause error util.jdbcexceptionreporter - cannot delete or update parent row: foreign key constraint fails , delete - recursively." well, seems whole point of referential integrity not you're trying in 2nd part of question. however, can add closure usersaddthese domain class: def beforedelete () { theseareconstantlygenerated.withnewsession { theseareconstantlygenerated.findallbytheproblem(this).each {theseareconstantlygenerated thing -> thing.delete() } } }...

i did wrong in code, other process send sigusr2 signal it: sigset_t sigset; sigemptyset(&sigset); sigaddset(&sigset, sigill); sigaddset(&sigset, sigusr2); sigwait(&sigset, &received); xcode notices siguser2(31) signal received, received = sigill(4) (or minimal signal in set). why so? wrong? now, looks this: sigset_t sigset; sigemptyset(&sigset); sigaddset(&sigset, sigill); sigaddset(&sigset, sigusr2); sigprocmask(sig_block, &sigset, 0); sigwait(&sigset, &received); if(received == sigusr2) { //... } else if(received == sigill) { //... } still not working. sometimes debugger can in way. have seen debuggers interfere signal handling before. try running code without debugger involved. the following code works on os x: #include <signal.h> #include <stdio.h> int main() { sigset_t set; int sig; sigemptyset(&set); sigaddset(&set, sig...

i have sql-server timestamp need convert representation of time in milliseconds since 1970. can plain sql? if not, i've extracted datetime variable in c#. possible millisec representation of ? thanks, teja. you're trying convert unix-like timestamp, in utc: yourdatetime.touniversaltime().subtract( new datetime(1970, 1, 1, 0, 0, 0, datetimekind.utc) ).totalmilliseconds this avoids summertime issues, since utc doesn't have those.

description / explanation: on "add event" page, can add multiple schedules. when saveall(), saves event data , schedule(s) data - working correctly. but then, want process schedule(s) data , build individual rows in "dates" table. event hasmany schedule schedule belongsto event schedule hasmany date date belongsto schedule so - i'm loading date model, , repeating through each schedule passed, , processing/inserting dates (based on repeat, start date...etc etc). my problem / question: i need id of each schedule it's dates ("schedule_id" field). how id's of individual schedules during repeat? currently, i'm doing this: foreach($this->data['schedule'] $i => $value) { $this->data['date']['schedule_id'] = $this->event->schedule->id; //other stuff here $this->date->saveall($this->data['date']); } but gives me same id in every loop. the problem i...
