i have simple code shows error. dont know going wrong. shows error in last line.."deleteonsubmit" linq_testdatacontext db = new linq_testdatacontext(); var remove = aremove in db.logins aremove.username == usernamestring && aremove.password == pwdstring select aremove; db.logins.deleteonsubmit(remove); you missing foreach loop delete entity. use below var remove = aremove in db.logins aremove.username == usernamestring && aremove.password == pwdstring select aremove; and after that foreach (var detail in remove) { db.logins.deleteonsubmit(detail); } and @ last try { db.submitchanges(); } catch (exception e) { // provide exceptions. } hope you.

i'm using velocity , spring. within spring, i'm using velocityviewresolver paired contentnegotiatingviewresolver . part, works great. problem contentnegotiatingviewresolver queries velocityviewresolver many different content sets (as should). when velocity engine doesn't find particular template, error produced similar following: 2011-02-04 13:37:15,074 error [http-8080-2] velocityengine: resourcemanager : unable find resource 'foo.json.vm' in resource loader. this not ideal. ideally, if template isn't found, warning or similar produced. if template doesn't exist particular content type, don't care... means content type isn't supported through view resolver. any idea on how suppress error though velocityviewresolver , velocityview , or contentnegotiatingviewresolver ? so, found best way add logger statement log config file velocity engine (velocity , project both use commons logging). logger statement looks this: ...

i can't figure out how take x (from code below) , add sum , divide number of ratings. example given in class 4 ratings, numbers being 3,4,1,and 2. average rating should 2.5, can't seem right! number_of_ratings = eval(input("enter number of difficulty ratings positive integer: ")) # number of difficulty ratings in range(number_of_ratings): # each diffuculty rating x = eval(input("enter difficulty rating positive integer: ")) # next difficulty rating average = x/number_of_ratings print("the average diffuculty rating is: ", average) your code doesn't add anything, overwrites x in each iteration. adding variable can done += operator. also, don't use eval : number_of_ratings = int(input("enter number of difficulty ratings positive integer: ")) x = 0 in range(number_of_ratings): x += int(input("enter difficulty rating positive integer: ")) average = x/number_of_ratings print("t...

i have set of checkboxes multiple choice allowed. parse set way: if ($("input[name='route_day']:checked").length > 0) { $("input[name='route_day']:checked").each(function(){ if(this.value != null) route_days_hook.push(this.value); }); datatrap.route_days = $.json.encode(route_days_hook); } ...and pull whole datatrap appengine python script via jquery ajax. however, python script bugs. if change datatrap.route_days value string instead of json encoded object, works fine. question is: how can pass checkbox set script using ajax , still able iterate on over script? have tried: datatrap.route_days = $.parsejson(route_days_hook); edit if didn't work, maybe it's because trying convert array object json... try solution instead.

here code: <?php $ja = ''; if(isset($ja)) echo "cool!"; ?> i "cool!" when running simple piece of code in browser. learned php.net isset — determine if variable set , not null well, in code, did declare variable $ja, didn't add value it, shouldn't "null"? even though '' seems nothing, still has value (a null character @ end of string). isset() checks if variable set or not, in case (to ''), is. may want set $ja null first beforehand, instead of setting empty string... or use empty() ;)

given array a[1..n] , want compute array b[1..n] such b[i] stores nearest element left of a[i] smaller a[i] . time complexity should o(n) . (for i>1 ,if there no such smaller elements left, b[i] contains a[i] , , b[1]=a[1] .) example : input : 6,9,12,17,11 output:6,6, 9, 12, 9 i thinking implementing stack, put a[1] in b[1] , push stack. filling b[i] ,compare a[i] elements of stack , pop till smaller element. push a[i] stack. is above approach correct, , there cheaper solution? your stack approach correct. works because if pop element bigger a[i] , element never needed elements following a[i] , because can use a[i] instead. each element accessed twice, o(n) .
