my column in table stores csv list of items. in c# have list of items , want linq query on column returning rows have of items in list. table defined as name|tags with example data of joe | football,soccer,basketball mike | hockey,soccer steve | basketball,baseball so if c# list contains soccer , basketball joe , steve since both have 1 of in tags list. note, i'm using entity framework table. you have bring entity data memory: var result = players.tolist() .where(item => item.tags.split(',').any(x => x.contains("basketball") || x.contains("baseball")); should give 2 results. update: providing list of sports list<string> sports = new list<string> { "baseball", "basketball", "football" }; var result = players.tolist() .where(item => item.tags.split(',').any(sports.contains))...

i'm trying make program tests if word palindrome using recursive function. pretty have working i'm having trouble getting move on next letter if first , last same. word = input("enterword") word = word.lower() def palindrom(word): if len(word) == 1 or len(word) == 0: return 0; if word[0] == word[-1]: print(word[0], word[-1]) palindrom(word); else: return 1; test = palindrom(word) if test == 0: print("yes") elif test == 1: print("no") so right tests if first , last letter same , if so, should run function again. need have check word[1] , word[-2] i'm having trouble. tried splitting word , popping letters kept looking @ list length of 1. if there way get length of whole split list, work well. you're missing return statement when call method recursively , correct slice: def palindrom(word): if len(word) == 1 or len(word) == 0: return 0 if word[0] == word[-...

rs.open "select [a$].security,[a$].name,sum([a$].[price]) [a$] inner join [b$] on [a$].security = [b$].id group [a$].security,[a$].description", cn, adopenkeyset, adlockreadonly the result query not align or match respective id in sheet b. example :- master worksheet aggregate records matching id of b , security of a. now, might have multiple instances of b's id having different price, reason why aggregate. question when paste record set data, see aggregated price value not pasted in front of id in b i.e want them ordered according id in b , order doesn't work, throwing error [b$].id not part of aggregate function. can hint on how can done ? try instead: rs.open "select [b$].id, [a$].name, sum([a$].[price]) [b$] left join [a$] on [b$].id = [a$].security group [b$].id, [a$].name", cn, adopenkeyset, adlockreadonly this should give total price each id in b , include ids b have no entries in a. every non-aggregated column in select clause has ...

i'm trying create note system. whatever type form gets put div. when user hits enter , submit note. want make when hit shift + enter creates line break point they're typing (like skype). here's code: $('#inputpnote').keypress(function(event){ var keycode = (event.keycode ? event.keycode : event.which); if(keycode=='13' && event.shiftkey){ $("inputpnote").append("<br>"); } else if(keycode == '13'){ var $pnote = document.getelementbyid("inputpnote").value; if ($pnote.length > 0) { $("#pnotes-list").append("<div class='pnote-list'><li>" + $pnote + "</li></div>"); $('#inputpnote').val(''); } } }); #inputpnote form user enters note , #pnotes-list place notes being appended to. thank in advance! i think you'd have set 2 global varia...

consider ping pong example http://www.golang-book.com/10/index.htm#section2 . package main import ( "fmt" "time" ) func pinger(c chan string) { := 0; ; i++ { c <- "ping" } } func ponger(c chan string) { := 0; ; i++ { c <- "pong" } } func printer(c chan string) { { msg := <- c fmt.println(msg) time.sleep(time.second * 1) } } func main() { var c chan string = make(chan string) go pinger(c) go ponger(c) go printer(c) var input string fmt.scanln(&input) } the authors write: "the program take turns printing ping , pong." however, true, go must decide on order in senders can send channel? otherwise, there no guarantee ping sent before pong (i.e. can't 2 pings, or 2 pongs in row). how work? there no synchronization between ping , pong goroutines, therefore there no guarantee responses print in order...
