i using asp.net 4.0 , mvc 2.0 web application. project requiremrnt have use server side control in application not possibl in noraml case. ideally want use adrotator control , datalist control. i saw few samples , references in codepleax mvc controllib howwver found less useful. can tell how utilize theese controls in asp.net application along mvc. note: please provide functionalities related adrotator , datalist controls not equivalent functionalities thanks in advace. mvc pages not use normal .net solution makes use of normal .net components impossible. a normal .net page use event driven solution call different methods service side mvc use actions , view completly different way handle things. also, mvc not use viewstate normal .net controlls require. found article discussing mixing of normal .net , mvc.

Ruby/RoR - Count occurrence of an element in an array -

-

i'v hash

{1=>true, 7=>false, 6=>true, 4=>false}

or array

[1, true], [7, false], [6, true], [4, false]]

or

[true, false, true, false].

how can find number of trues in array?

in order count elements, have iterate on collection. since iterating on hash yields two-element arrays, first 2 same:

{ 1 => true, 7 => false, 6 => true, 4 => false }.count(&:last) [[1, true], [7, false], [6, true], [4, false]].count(&:last)

for simple array case, this:

[true, false, true, false].count(true)

this array of course same hash#values hash above, use same method on that:

{ 1 => true, 7 => false, 6 => true, 4 => false }.values.count(true)

if don't know 1 of 3 get, use this:

{ 1 => true, 7 => false, 6 => true, 4 => false }.flatten.count(true) [[1, true], [7, false], [6, true], [4, false]].flatten.count(true) [true, false, true, false].flatten.count(true)

cocoa - Nesting arrays into NSDictionary object (Objective-C) -

-
i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
