how can convert varchar data '20130120161643730' datetime ? convert(datetime, '20130120161643730') not work. however, convert (datetime, '20130120 16:16:43:730') works. guess needs data in correct format. is there valid way can used convert datetime directly unformatted data ? my solution : declare @var varchar(100) = '20130120161643730' select concat(left(@var,8),' ',substring(@var,9,2),':',substring(@var,11,2),':',substring(@var,13,2),':',right(@var,3)) it works fine. however, i'm looking compact solution. you can make little more compact not forcing dashes, , using stuff instead of substring : declare @var varchar(100) = '20130120161643730'; set @var = left(@var, 8) + ' ' + stuff(stuff(stuff(right(@var, 9),3,0,':'),6,0,':'),9,0,'.'); select [string] = @var, [datetime] = convert(datetime, @var); results: string dateti

in project, have been using bluetooth module (panasonic pan1321) transfer real-time data sensors android tablet @ approx 200hz (this rate @ data packets transferred). considering use wifi instead. understanding has longer range , more robust. plus many wireless systems out there use easier integrate system existing setups. intend use bluegiga wf121 wifi node. module offers tcp or udp communication. have no knowledge of tcp or udp. appreciate if has answers following questions: is worthwhile shift bluetooth wifi? will able point-to-point data transfer between wifi module , android tablet (just bluetooth module)? on wifi can achieve data transfer rate of upto 500hz data packet size of approx 80 120 bytes? 500hz more enough real-time feedback in project 200hz suffice. having lower data transfer rate possible increase memory requirement embedded system , can bottle-neck. there time-stamp included in data packet timing of packets not important order of packets more important. pac

i wondering whether explain how small code snippet works. void reverse(char *s) { if(*s) reverse(s+1); else return; cout << *s; } when call function in main, supposedly prints out reverse of string put in (ie. hello cout olleh) don't understand how. understand it, if statement increases value of s until reaches end of string, printing out each value in string goes. why doesn't re-print string. missing something. (sorry btw, new c++ , recursive functions) consider how "hello" string stored in memory: let's address of 'h' character happens 0xc000 . rest of string stored follows: 0xc000 'h' 0xc001 'e' 0xc002 'l' 0xc003 'l' 0xc004 'o' 0xc005 '\0' now consider series of invocations of reverse : initial invocation passes 0xc000 ; call of reverse inside reverse passes s+1 , next level gets 0xc001 ; next 1 gets 0xc002 , , on. note each level calls next level, un

it seems have correctly imported package , class, yet reason, variable user not found. user object of type string created in class addto. <%@ page import= "package1.addto" %> <html> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8"> <title>jsp page</title> </head> <body> <p> shopping cart</p> <%= system.out.println(user.name); %> </body> </html> you import class package, , not it's fields. that being said, should add addto object request attribute in servlet, , access attribute in jsp using el . should not use scriplets in new code. in servlet do: request.setattribute("addto", addto); then in jsp, can access user property of attribute addto as: <p> shopping cart</p> ${addto.user} <!-- access user property of addto attribute, object of type `addto` --> see also: how

i'm learning javascript fun, , having weird problem. i'm trying create own fade-in function. however, code doesn't work, shows "content" div in full opacity. the setcontentopacity function does work, i've tested , works charm. ideally think should happening 1000 "settimeout" calls should placed on "stack", first 1 setting opacity low no timeout, second 1 setting opacity little higher small timeout, way last call sets opacity 1000 3000 timout. so basically, should setting opacity 0 right away, ~333 in 1 second, ~666 in 2 seconds, , 1000 in 3 seconds. think logic sound here; calls setting opacity should resolve in manner on time creates fade in effect. so here's relevent code: <script language='javascript' type='text/javascript'> //takes value 0-1000 function setcontentopacity(value) { document.getelementbyid('content').style.opacity = value/1000; document.getelementbyid('content'

my code looks like: nspredicate* pred = [nspredicate predicatewithformat:@"(title in %@)", prev_set]; nsset* remainingset = [goal_set filteredsetusingpredicate:pred ]; where prev_set , goal_set 2 different sets. "title" in property in objects contained in both sets. my objective goals rejected if have been met (each goal having unique title). if have predicate "title in %@" of objects in goal_set rejected. if use "not("title in %@)", none of objects in goal_set rejected. if print out both sets, see have (but not all) objects in common (that is, title same). am confused use of "in" nspredicates? how accomplish objective? try [nspredicate predicatewithformat:@"not (title in %@.title)", prev_set] . your predicates assume prev_set contains nsstring objects, according description, contains objects have string property , never contain titles themselves. hope makes sense.

i enumerate through bitarray setting every second bit false. now i'd speed splitting 2 threads.. weird reason though, time per thread half amount of work takes 64% more time, , wonder why's that? could due kind of cpu caching effect? how do properly? i have tried 8 threads lambda expressions around ~1400 ms, in single threading constandly got 850 ms. when let single thread work, took me 830 ms. don't understand, knowing cause here? code: class program { static int count = 0x10000000; static int half = count / 2; static bitarray bitarray = new bitarray(count); static unsafe void main(string[] args) { stopwatch sw = stopwatch.startnew(); #if single (int = 0; < bitarray.count; += 2) bitarray.set(i, true); #else thread thread1 = new thread(thread1); thread thread2 = new thread(thread2); thread1.start(); thread2.start();
